The first jaw 10 includes a first collet 11 and a first grip 12, one end of the first grip 12 is fixedly connected to the first collet 11, and an end, away from the first grip 12, of the first jaw 10 is formed with a first pressing end 111. The second jaw 20 includes a second collet 21 and a second grip 22, wherein one end of the second grip 22 is rotatably connected to the second collet 21, an end, away from the second grip 22, of the second collet 21 is formed with a second pressing end 211, and the second collet 21 is rotatably connected to the first grip 12. The connection between the second grip 22 and the connecting rod 40 is set as a first connection point 212, the connection between the second collet 21 and the second grip 22 is set as a second connection point 213, and the first connection point 212 is located on a side, away from the second pressing end 211, of the second connection point 213.
The pressing tool 100 further includes a connecting rod 40 and a resilient member 50. The connecting rod 40 is rotatably connected at one end to the first grip 12 and at the other end to the second grip 22 to control a range of rotation of the second grip 22 and the second collet 21. The resilient member 50 is connected at one end to the second collet 21 and at the other end to the first grip 12.
The pressing tool 100 has an expanded state and a pressing state, and the first workpiece 200 and the second workpiece 300 can be placed between the positioning portion 30 and the first pressing end 111 when the pressing tool 100 is in the expanded state. The first workpiece 200 and the second workpiece 300 may be pressed when the tool is in a pressing state. It will be appreciated that when the pressing tool 100 is in a pressing state, the first pressing end 111 does not necessarily contact the positioning portion 30, but may be provided that the pressing portion is spaced from the positioning portion 30, and may be adjusted as required actually.
When the pressing tool 100 is in the pressing state, the resilient member 50 is in a stretched state and applies an elastic force to the second collet 21 so that the second collet 21 is subjected to a force rotating in a direction away from the first collet 11, and an extension direction of the straight line where the first connection point 212 and the second connection point 213 are located coincides with an extension direction of the connecting rod 40 so as to block the second collet 21 from rotating in a direction away from the first collet 11.
A force is applied to the second grip 22 in a direction away from the first grip 12. The extension direction of the straight line where the first connection point 212 and the second connection point 213 are located intersects with the extension direction of the connecting rod 40); and under the elastic force of the resilient member 50, the second collet 21 can rotate in a direction away from the first collet 11, and at the same time, the second grip 22 also rotates in a direction away from the first grip 12, when the pressing tool 100 is in an open state. The connecting rod 40 is connected to the first grip 12 and the second grip 22 to block the second grip 22 from continuing to rotate in a direction away from the first grip 12. Further, when the pressing tool 100 is in a pressing state, the connecting rod 40 contacts the second grip 22 to block the second grip 22 from rotating in a direction closer to the first grip 12, so that the connecting rod 40) can control the range of rotation of the first grip 12 and the second grip 22. Alternatively, the resilient member 50 is a spring.
Optionally, in some embodiments, the pressing tool 100 further includes an adjustment screw 60 extending in a direction coincident with the extension direction of the first grip 12, the adjustment screw 60 being threadably connected to the first grip 12, the adjustment screw 60 being located at an end, away from the first collet 11, of the first grip 12. The connecting rod 40 is rotatably connected to the adjustment screw 60 such that the connecting rod 40 is rotatably connected to first grip 12 via the adjustment screw 60. The relative position of the end, away from the second grip 22, of the connecting rod 40 with the first grip 12 can be adjusted by turning the adjustment screw 60 so that the distance between the first collet 11 and the second collet 21 can be adjusted.
Taking the pressing tool 100 in a pressing state as an example, the adjusting screw 60 is rotated to move the connecting rod 40 in a direction close to the first collet 11. Since the angle between the extension direction of the first screw and the extension direction of the first grip 12 remains fixed, and the extension direction of the connecting rod 40 coincides with the extension direction of the straight line in which the first connection point 212 and the second connection point 213 are located, the second grip 22 gradually pushes the second collet 21, so that the second collet 21 gradually rotates towards the first collet 11, so as to shorten the distance between the first collet 11 and the second collet 21, which is applicable to the first workpiece 200 and the second workpiece 300 with a smaller size. Accordingly, when the adjustment screw 60 is rotated to rotate the connecting rod 40 in a direction away from the first collet 11, the distance between the first collet 11 and the second collet 21 can be increased.
Optionally, in some embodiments, the pressing tool 100 further includes a release handle 70 rotatably connected to the second grip 22, an end, away from the second collet 21, of the release handle 70 being rotatable when the pressing tool 100 is in the pressing state such that the other end of the release handle 70 pushes the connecting rod 40. When the pressing tool 100 is in the pressing state, an end, away from the first collet 11, of the release handle 70 is pushed toward the second grip 22, and an end, close to the second collet 21, of the release handle 70 pushes the connecting rod 40 so that the connecting rod 40 rotates and the extension direction of the connecting rod 40 intersects with the extension direction of a straight line where the first connection point 212 and the second connection point 213 are located. The release handle 70 is equivalent to a force-saving handle, and can make the pressing tool 100 switch from the pressing state to an opening state in a more force-saving manner.
Alternatively, in some embodiments, the connecting rod 40 is provided with a push block 41 through which the release handle 70 pushes the connecting rod 40 at an end close to the first collet 11. The push block 41 is in contact with one end of the release handle 70 to better push the connecting rod 40 to rotate when the release handle 70 is rotated.
