The present application relates to the technical field of mechanical apparatus, in particular to a bottle cap opening and closing device and an experimental apparatus.
Container bottle include bodies and caps and are used to hold liquids. To ensure the sealing of the container bottle, the bottle cap is usually connected to the bottle body through threaded connection. At present, it is usually necessary to use a bottle cap opening and closing device to open the container bottle. The bottle cap opening and closing device usually includes a bottle body clamping mechanism and a bottle cap clamping mechanism. When opening a container bottle, the bottle body is fixed by the bottle body clamping mechanism, and the bottle cap is clamped and rotated by the bottle cap clamping mechanism. However, when the bottle cap and the bottle body are excessively tightened, there may be situations where the bottle cap opening and closing device cannot open the container bottle.
In a first aspect, the present disclosure provides a bottle cap opening and closing device which includes a base, a bottle body clamping mechanism which is rotatably arranged on the base and is used for clamping a bottle body, a first buffer mechanism which is arranged between the bottle body clamping mechanism and the base, a bottle cap clamping mechanism which is arranged opposite the bottle body clamping mechanism and is used for clamping a bottle cap, and a rotation driving mechanism which is in driving connection with the bottle body clamping mechanism and drives the bottle body clamping mechanism to rotate relative to the bottle cap clamping mechanism so as to enable the bottle body and the bottle cap to be relatively tightened or separated from each other.
In a second aspect, the present disclosure provides an experimental apparatus which includes an experimental platform and a bottle cap opening and closing device described above, wherein the bottle cap opening and closing device is arranged on the experimental platform.
According to the bottle cap opening and closing device provided in an embodiment of the present disclosure, the bottle body is clamped by the bottle body clamping mechanism, the bottle cap is clamped by the bottle cap clamping mechanism, and the bottle body clamping mechanism is driven to rotate by the rotation driving mechanism. The bottle body clamping mechanism rotates to drive the bottle body to rotate relative to the bottle cap. Moreover, under the action of the first buffer mechanism, the excessive tightening of the bottle body and the bottle cap and the damage caused by it can be avoided. According to the present disclosure, during the process of opening or tightening the bottle cap, the bottle body clamping mechanism applies a rotational force to the bottle body. Compared with the traditional technical solution where a bottle cap clamping mechanism applies a rotational force to the bottle cap, the torque is greater, making it easier to open or tighten the bottle cap.

According to the technical solution provided by an embodiment of the present disclosure, the bottle body is clamped by the bottle body clamping mechanism 20, the bottle cap is clamped by the bottle cap clamping mechanism 40, and the bottle body clamping mechanism 20 is driven to rotate by the rotation driving mechanism 50. The bottle body clamping mechanism 20 rotates to drive the bottle body to rotate relative to the bottle cap. Moreover, under the action of the first buffer mechanism 30, the excessive tightening of the bottle body and the bottle cap and the damage caused by it can be avoided. According to an embodiment of the present disclosure, during the process of opening or tightening the bottle cap, the bottle body clamping mechanism 20 applies a rotational force to the bottle body. Compared with the traditional technical solution where a bottle cap clamping mechanism applies a rotational force to the bottle cap, the torque is greater, making it easier to open or tighten the bottle cap.
As shown in
Specifically, the bottle body is placed between the first clamping assembly 22 and the second clamping assembly 23, and the clamping of the bottle body is achieved through the cooperation of the first clamping assembly 22 and the second clamping assembly 23. Because at least one of the first clamping assembly 22 and the second clamping assembly 23 is provided with a second buffer mechanism, when clamping the bottle body, the clamping assembly provided with the second buffer mechanism can pre-press the bottle body, and overpressure on the bottle body can be avoided, which can reduce the clamping force of the clamping assembly on the bottle body, and thereby reducing the damage to the bottle body due to excessive clamping force. Besides, the drive mechanism is in driving connection with at least one of the first clamping assembly 22 and the second clamping assembly 23, which can achieve automatically clamping the bottle body and improve the convenience of clamping the bottle body.
In this embodiment, the second buffer mechanism includes a first buffer component 24. The first clamping assembly 22 includes a first connecting part 221 and a first bottle body clamping part 222. Specifically, the first connecting part 221 is arranged on the support seat 21. The first bottle body clamping part 222 is arranged at one side of the first connecting part 221 near the second clamping assembly 23. The first buffer component 24 is arranged between the first connecting part 221 and the first bottle body clamping part 222, and the first bottle body clamping part 222 is movable relative to the first connecting part 221 through the first buffer component 24. When clamping the bottle body, after the first bottle body clamping part 222 presses against the bottle body, the bottle body exerts a certain force on the first bottle body clamping part 222. Under the action of the buffer component, the first bottle body clamping part 222 has a tendency to move away from the bottle body and moves away from the bottle body so as to avoid excessive pressure on the bottle body, avoiding or reducing the possibility of crushing the bottle body.
In an implementation, the first buffer component 24 includes a first elastic member 241. One end of the first elastic member 241 is connected to the first connecting part 221, and the other end of the first elastic member is connected to the first bottle body clamping part 222. When clamping the bottle body, after the first bottle body clamping part 222 presses against the bottle body, the bottle body exerts a certain force on the first bottle body clamping part 222. Under the action of the first bottle body clamping part 222, the first elastic member 241 is compressed to achieve a buffering effect, reducing the clamping force of the first bottle body clamping part 222 on the bottle body.
In an implementation, the first bottle body clamping part 222 is a block structure, and the first connecting part 221 is a block structure. The length direction of the first bottle body clamping part 222 is perpendicular to the direction from the first clamping assembly 22 to the second clamping assembly 23. The length direction of the first connecting part 221 is the same as the length direction of the first bottle body clamping part 222, and the first connecting part 221 is arranged right opposite to the first bottle body clamping part 222. One end of the first elastic member 241 is connected to a side wall of the first connecting part 221 at the side near the first bottle body clamping part 222, and the other end of the first elastic member 241 is connected to a side wall of the first bottle body clamping part 222 at the side near the first connecting part 221.
In this embodiment, two first elastic members 241 are provided. The two first elastic members 241 are spaced along the length direction of the first bottle body clamping part 222. By this configuration, the buffering effect of the first elastic members 241 on the first bottle body clamping part 222 can be further ensured, the uniformity of the force exerted by the first bottle body clamping part 222 on the bottle body can be ensured, and the possibility of crushing the bottle body can be reduced.
In an implementation, one first elastic member 241 is provided. One end of the first elastic member is connected to the middle of a side wall of the first bottle body clamping part 222 at the side near the first connecting part 221, and the other end of the first elastic member 221 is connected to the middle of a side wall of the first connecting part 221 at the side near the first bottle body clamping part 222. By this configuration, the uniformity of the force exerted by the first elastic member 241 on the first bottle body clamping part 222 and the uniformity of the force exerted by the first elastic member 241 on the first connecting part 221 can be ensured, further improving the stability of the first bottle body clamping part 222 in clamping the bottle body.
In an implementation, at least three first elastic members 241 are provided. Multiple first elastic members 241 are spaced along the length direction of the first bottle body clamping part 222. By this configuration, the buffering effect of the first elastic members 241 can be further enhanced, ensuring the steady movement of the first bottle body clamping part 222 relative to the first connecting part 221.
In this embodiment, the first elastic member 241 is the first spring, and the expansion and contraction direction of the first spring is the same as the direction from the first connecting part 221 to the first bottle body clamping part 222. One end of the first spring is connected to the first connecting part 221, and the other end of the first spring is connected to the first bottle body clamping part 222. The first spring has a simple structure, good buffering effect, large telescopic amount and convenient installation.
In an implementation, the first elastic member 241 is the first elastic sheet. One end of the first elastic sheet is connected to the first connecting part 221, and the other end of the first elastic sheet is connected to the first bottle body clamping part 222. The first elastic sheet has a simple structure and convenient installation.
In an implementation method, the first elastic member 241 is a first rubber block. One end of the first rubber block is connected to the first connecting part 221, and the other end of the first rubber block is connected to the first bottle body clamping part 222. The first rubber block has a simple structure.
In this embodiment, the first buffer component 24 further includes first guide rods 242. The first guide rod 242 is arranged between the first connecting part 221 and the first bottle body clamping part 222. The first guide rod 242 is used to guide the movement of the first bottle body clamping part 222 relative to the first connecting part 221. In this embodiment, the number of first guide rods 242 is the same as the number of the first springs. The first guide rods 242 are correspondingly arranged with the first springs, and the extension direction of the first guide rod 242 is the same as the direction from the first connecting part 221 to the first bottle body clamping part 222. The first spring is wound on the first guide rod 242. This configuration allows the first guide rods 242 to guide the expansion and contraction of the first springs, ensuring smoothness and stability of the first springs during the expansion and contraction process, thereby improving the smoothness of the movement of the first bottle body clamping part 222 relative to the first connecting part 221, and maximizing the uniformity of the force exerted by the first bottle body clamping part 222 on the bottle body, and ensuring stability during the clamping process.
In this embodiment, first guide holes are formed in the first connecting part 221. The number of the first guide holes is the same as the number of the first guide rods 242. The first guide holes are correspondingly arranged with the first guide rods 242, The axis direction of the first guide hole is the same as the extension direction of the first guide rod 242. One end of the first guide rod 242 is fixedly connected to the first bottle body clamping part 222, The other end of the first guide rod 242 is inserted into the first guide hole and is movable in the first guide hole. The first guide rod 242 is in match with the first guide hole to guide the movement of the first bottle body clamping part 222 relative to the first connecting part 221. Specifically, the end of the first bottle body clamping part 222 near the first connecting part 221 is provided with the first threaded holes. The number of the first threaded holes is the same as the number of the first guide holes. The first threaded hole is opposite to the first guide hole. The first guide rod 242 includes a first threaded section, a first rod body section and a first stop section sequentially connected along the direction from the first bottle body clamping part 222 to the first connecting part 221. Specifically, the diameter of the first rod body section is smaller than the diameter of the first guide hole, the diameter of the first stop section is greater than the diameter of the first guide hole, and the first threaded section passes through the first guide hole and is threaded to the first threaded hole. After the first bottle body clamping part 222 presses against the bottle body, the first spring is compressed, and the first bottle body clamping part 222 moves in the direction close to the first connecting part 221. The first bottle body clamping part 222 moves to drive the first guide rod 242 to move. The elasticity of the first spring will be damaged after repeated compression for a long time. The above configuration facilitates timely replacement of the first spring, ensuring the elasticity of the first spring, and thus ensuring the clamping effect of the first bottle body clamping part 222 on the bottle body.
In an implementation, second guide holes are formed in the first bottle body clamping part 222. The number of the second guide holes is the same as that of the first guide rods 242. The second guide holes are correspondingly arranged with the first guide rods 242. The axis direction of the second guide hole is the same as the extension direction of the first guide rod 242. One end of the first guide rod 242 is fixedly connected to the first connecting part 221. The other end of the first guide rod 242 is inserted into the second guide hole and is movable in the second guide hole. The first guide rod 242 is in match with the second guide hole to guide the movement of the first bottle body clamping part 222 relative to the first connecting part 221. The end of the first connecting part 221 near the first bottle body clamping part 222 is provided with the second threaded holes. The number of the second threaded holes is the same as the number of the second guide holes. The second threaded hole is opposite to the second guide hole. The second guide hole is a blind hole in a step-like manner. The second guide hole includes the first through hole and the second through hole in communication with each other. The first through hole is arranged near the first connecting part 221. The diameter of the first through hole is smaller than the diameter of the second through hole. The first guide rod 242 is cylindrical, and the first guide rod 242 includes a first clamping part and a first main body section that are sequentially connected. The diameter of the first clamping part is greater than the diameter of the first main body section. The first clamping part is movably arranged in the second threaded hole. One end of the first main body section that is far away from the first clamping part passes through the second through hole and the first through hole in sequence and is threaded to the second threaded hole. After the first bottle body clamping part 222 presses against the bottle body, the first bottle body clamping part 222 moves in the direction close to the first connecting part 221 under the action of the first spring. The second through hole provides an avoidance space for the movement of the first bottle body clamping part 222. By this configuration, the situation where the end of the first guide rod 242 protrudes from the first bottle body clamping part 222 during the movement of the first bottle body clamping part 222 can be avoided, thereby avoiding interference when the first guide rod 242 clamps the bottle body and ensuring the smoothness of clamping the bottle body.
In this embodiment, the second clamping assembly 23 includes a second bottle body clamping part 231 and a second connecting part 232. The second bottle body clamping part 231 is arranged opposite to the first bottle body clamping part 222, and the second bottle body clamping part 231 is in cooperation with the first bottle body clamping part 222 to clamp the bottle body. The second connecting part 232 is connected to the second bottle body clamping part 231, and the second connecting part 232 is arranged at the side of the second bottle body clamping part 231 away from the first bottle body clamping part 222. The second bottle body clamping part 231 and the second connecting part 232 are both block shaped structures. The length direction of the second bottle body clamping part 231 is the same as that of the first bottle body clamping part 222. The length direction of the second connecting part 232 is the same as that of the second bottle body clamping part 231. The second bottle body clamping part 231 is arranged right opposite to the first bottle body clamping part 222. By this configuration, the uniformity of force on the bottle body can be ensured, and the possibility of the bottle body being crushed due to uneven force on the bottle body can be reduced.
In an implementation, two first connecting threaded holes are formed in the end face of the second bottle body clamping part 231 at one end near the second connecting part 232. The two first connecting threaded holes are distributed along the length direction of the second bottle body clamping part 231. The extension direction of the first connecting threaded hole is perpendicular to the length direction of the second bottle body clamping part 231. Two second connecting threaded holes are formed in the end face of the second connecting part 232 at one end near the second bottle body clamping part 231. The first connecting threaded hole is opposite to the second connecting threaded hole, and the second connecting threaded hole penetrates through the second connecting part 232. The second clamping assembly 23 further includes two connecting screws 233. The two connecting screws 233 and the second threaded holes are arranged in a one-to-one correspondence manner. One end of the connecting screw 233 passes through the second threaded hole and is threaded to the first threaded hole. This configuration facilitates the assembly and disassembly of the second connecting part 232 and the second bottle body clamping part 231.
In this embodiment, one end of the first bottle body clamping part 222 near the second bottle body clamping part 231 has a first bottle body clamping surface, and there are a plurality of contact regions between the first bottle body clamping surface and the bottle body and an angle is formed between the plurality of contact regions of the first bottle body clamping surface. One end of the second bottle body clamping part 231 near the first bottle body clamping part 222 has a second bottle body clamping surface. The second bottle body clamping surface and the first bottle body clamping surface have a same structure and form a mirror symmetrical structure. Specifically, the first bottle body clamping surface and the second bottle body clamping surface are both V-shaped. When clamping the bottle body, the first bottle body clamping surface and the second bottle body clamping surface are opposite to each other and both press against the bottle body. By this configuration, the uniformity of force on the bottle body can be ensured, and bottle bodies of different sizes and different shapes can be clamped, improving the adaptability of the device.
In an implementation, both the first bottle body clamping surface and the second bottle body clamping surface are trapezoidal.
In an implementation, the contact region between the first bottle body clamping surface and the bottle body is at a cambered surface of the first bottle body clamping surface, and the contact region between the second bottle body clamping surface and the bottle body is at a cambered surface of the second bottle body clamping surface. The axis direction of the cambered surface of the first bottle body clamping surface and the axis direction of the cambered surface of the second bottle body clamping surface are both vertical.

In an implementation, the first elastic structure on the first bottle body clamping surface and the first elastic structure on the second bottle body clamping surface both have a first anti-slip structure provided thereon. The first anti-slip structure is the first anti-slip pattern. By providing the first anti-slip pattern, the friction force between the first and second bottle body clamping parts 222, 231 and the bottle body can be increased, ensuring the stability of clamping the bottle body.
In an implementation, the first anti-slip structure is the first anti-slip particles. By providing the first anti-slip particle, the friction force between the first and second bottle body clamping parts 222, 231 and the bottle body can be increased, ensuring the stability of clamping the bottle body.

When clamping the bottle body, the bottle body is engaged with the second clamping assembly 23, and then the first driving assembly 25 is activated. The first driving assembly 25 drives the first clamping assembly 22 close to the bottle body until the first clamping assembly 22 presses against the bottle body, completing the clamping of the bottle body. By this configuration, the second clamping assembly 23 can be used as the reference side, and the position of the first clamping assembly 22 relative to the bottle body can be slightly adjusted through the first driving assembly 25 to ensure the effect of clamping the bottle body.
In an implementation, the first clamping assembly 22 is fixedly arranged on the support seat 21. The driving mechanism includes the second driving assembly 26. The second driving assembly 26 is drive-connected to the second clamping assembly 23. When clamping the bottle body, the bottle body is engaged with the first clamping assembly 22, and then the second driving assembly 26 is activated. The second driving assembly 26 drives the second clamping assembly 23 close to the bottle body until the second clamping assembly 23 presses against the bottle body, completing the clamping of the bottle body. With this configuration, after the second clamping assembly 23 presses against the bottle body, the first spring contracts under the action of the first bottle body clamping part 222. By this configuration, the possibility of the bottle body being crushed can be reduced.
In this embodiment, the drive mechanism includes a first driving assembly 25 and a second driving assembly 26. The first driving assembly 25 is connected to the first clamping assembly 22 to move the first clamping assembly 22 in the direction facing to or opposite the second clamping assembly 23. The second driving assembly 26 is drive-connected to the second clamping assembly 23 to move the second clamping assembly 23 in the direction facing to or opposite the first clamping assembly 22.

When clamping the bottle body, the bottle body is placed on the support seat 21, and then the first driving assembly 25 and the second driving assembly 26 are activated. Under the drive of the first driving assembly 25 and the second driving assembly 26, the first clamping assembly 22 and the second clamping assembly 23 move independently and close to the bottle body. By this configuration, the second clamping assembly 23 can be used as the reference side, and the position of the first clamping assembly 22 relative to the bottle body can be slightly adjusted to ensure the effect of clamping the bottle body.

One end of the first screw nut pair passes through the first sliding slot and is threaded to the first screw rod, and the other end of the first screw nut pair is drive-connected to the first connecting part 221. When clamping the bottle body, the first driving motor rotates to drive the first screw rod to rotate, and the first screw rod rotates to drive the first screw nut pair to move the first clamping assembly 22. The first screw rod is in cooperation with the first screw nut pair and they have a self-locking function, ensuring stability in clamping the bottle body.

According to the technical solutions of applying an embodiment of the present disclosure, the bottle cap clamping mechanism 40 is provided with a first gripper assembly and a second gripper assembly. When it is needed to clamping the bottle cap, the first gripper assembly or the second gripper assembly can be selected to clamp the bottle cap based on the type of the bottle cap or the circumstance in which the bottle cap is located. Compared with traditional technical solutions, in this embodiment, the first gripper assembly and the second gripper assembly are both driven by the third driving member 42, thereby reducing the number of the driving members and the size of the bottle cap clamping mechanism 40, and reducing the weight and cost of the bottle cap clamping mechanism 40. Moreover, the first gripper assembly and the second gripper assembly can perform gripping actions independently, facilitating the clamping of different types of bottle caps and expanding the application scope of the bottle cap clamping mechanism 40.
The first gripper assembly and the second gripper assembly may have the same structure, or have different structures.

Each of the first bottle cap clamping parts 43 has a first bottle cap clamping surface, and the plurality of first bottle cap clamping parts 43 are in cooperation with each other through a plurality of first bottle cap clamping surfaces to clamp the bottle cap. When it is needed to clamp an object, the plurality of first bottle cap clamping parts 43 of the first gripper assembly approach the bottle cap to be clamped until the plurality of first bottle cap clamping surfaces all press against the bottle cap to be clamped. By arranging the plurality of clamping parts, bottle caps of different sizes and different shapes can be clamped, improving the adaptability of the first gripper assembly.

The baffle 751 can limit the displacement of the lifting plate 72 in combination with the limit sensor 481. The limit sensor 481 is electrically connected to the fourth driving member 471. When the first lifting plate 472 rises to approach the fourth driving member 471, the limit sensor 481 and the limit baffle 482 sense each other, the limit sensor 481 transmits the position signal of the first lifting plate 472 to the fourth driving member 471, the fourth driving member 471 is stopped, and the first lifting plate 472 stops rising. Through the cooperation of the limit baffle 482 and the limit sensor, the displacement of the first lifting plate 472 can be limited, and collision between the first lifting plate 472 and the fourth driving member 471 can be therefore avoided.

One end of the second buffer component is connected to the second bottle body clamping part 231, and the other end of the second buffer component is connected to the second connecting part 232. The second bottle body clamping part 231 is movable relative to the second connecting part 232 through the second buffer component. With this configuration, when the second bottle body clamping part 231 presses against the bottle body, the second bottle body clamping part 231 moves in a direction close to the second connecting part 232 under the action of the second buffer component to reduce the force on the bottle body and further reduce or avoid crushing the bottle body. Specifically, the second buffer component includes a second elastic member. One end of the second elastic member is connected to the second connecting part 232, and the other end of the second elastic member is connected to the second bottle body clamping part 231.
In this embodiment, two second elastic members are arranged, and the two second elastic members are spaced along the length direction of the second bottle body clamping part 231. By this configuration, the buffering effect of the second elastic members on the second bottle body clamping part 231 can be further ensured, ensuring the uniformity of the force exerted by the second bottle body clamping part 231 on the bottle body and reducing the possibility of the bottle body being crushed.
In an implementation, one second elastic member is arranged.

In an implementation, at least three second elastic members are arranged, and the plurality of second elastic members are spaced along the length direction of the second bottle body clamping part 231. By this configuration, the buffering effect of the second elastic members can be further enhanced and the stable movement of the second bottle body clamping part 231 relative to the second connecting part 232 can be ensured.
Specifically, the second elastic member is the second spring, and the expansion and contraction direction of the second spring is the same as the direction from the second connecting part 232 to the second bottle body clamping part 231. One end of the second spring is connected to the second connecting part 232, and the other end of the second spring is connected to the second bottle body clamping part 231. The second spring has a simple structure, good buffering effect, large telescopic amount and convenient installation.
In an implementation, the second elastic member is the second elastic sheet.

In an implementation, the second buffer component further includes second guide rods which are arranged between the second connecting part 232 and the second bottle body clamping part 231. The second guide rods are used to guide the movement of the second bottle body clamping part 231 relative to the second connecting part 232. The number of the second guide rods is the same as the number of the second springs, and the second guide rods are arranged corresponding to the second springs. And the extension direction of the second guide rod is the same as the direction from the second connecting part 232 to the second bottle body clamping part 231. The second spring is wound on the second guide rod. This configuration allows the second guide rod to guide the expansion and contraction of the second spring, ensuring smoothness and stability during the expansion and contraction process of the second spring, thereby improving the smoothness of the movement of the second bottle body clamping part 231 relative to the second connecting part 232, and maximizing the uniformity of the force exerted by the second bottle body clamping part 231 on the bottle body, ensuring smoothness of the clamping process.
In an implementation, third guide holes are formed in the second connecting part 232, and the number of the third guide holes is the same as the number of the second guide rods.

One end of the second guide rod is fixedly connected to the second bottle body clamping part 231, and the other end of the second guide rod is inserted into the third guide hole and is movable in the third guide hole. The second guide rod is in match with the third guide hole to guide the movement of the second bottle body clamping part 231 relative to the second connecting part 232. The end of the second bottle body clamping part 231 near the second connecting part 232 is provided with third threaded holes. The number of the third threaded holes is the same as the number of the third guide holes. The third threaded holes are opposite to the third guide holes. The second guide rod includes a second threaded section, a second rod body section and a second stop section sequentially connected along the direction from the second bottle body clamping part 231 to the second connecting part 232. Specifically, the diameter of the second rod body section is smaller than the diameter of the third guide hole, and the diameter of the second stop section is greater than the diameter of the third guide hole. The second threaded section passes through the third guide hole and is threaded to the third threaded hole. When the second bottle body clamping part 231 presses against the bottle body, the second spring is compressed, and the second bottle body clamping part 231 moves in the direction close to the second connecting part 232. The second bottle body clamping part 231 moves to drive the second guide rod to move. After repeated compression for a long time, the elasticity of the second spring is damaged. The above configuration facilitates the timely replacement of the second spring, ensuring the elasticity of the second spring, and thus ensuring the clamping effect of the second bottle body clamping part 231 on the bottle body.
In an implementation, fourth guide holes are formed in the second bottle body clamping part 231. The number of the fourth guide holes is the same as that of the second guide rods. The fourth guide holes are arranged corresponding to the second guide rods. The axis direction of the fourth guide hole is the same as the extension direction of the second guide rod. One end of the second guide rod is fixedly connected to the second connecting part 232, and the other end of the second guide rod is inserted into the fourth guide hole and is movable in the fourth guide hole. The second guide rod is in match with the fourth guide hole to guide the movement of the second bottle body clamping part 231 relative to the second connecting part 232.

The diameter of the second clamping part is greater than the diameter of the second main body section. The second clamping part is movably arranged in the fourth threaded hole. The end of the second main body section far away from the second clamping part passes through the fourth threaded hole and the third threaded hole in sequence and is threaded to the fourth threaded hole. After the second bottle body clamping part 231 presses against the bottle body, the second bottle body clamping part 231 moves in the direction close to the second connecting part 232 under the action of the first spring. The fourth through hole provides an avoidance space for the movement of the second bottle body clamping part 231. By this configuration, the situation where the end of the second guide rod protrudes from the second bottle body clamping part 231 during the movement of the second bottle body clamping part 231 can be avoided, thereby avoiding interference when the second guide rod clamps the bottle body and ensuring smoothness of clamping the bottle body.
