Therefore, the first seat body 3 and the second seat body 9 are not limited to the above-mentioned detachable connection, and any detachable connection formed between the first seat body 3 and the second seat body 9 fall within the scope of the present invention.

The locking mechanism comprises a first lock portion 4, a flipping portion 5, a connection portion 6 and a second lock portion 7, the first lock portion 4 is connected to the first seat body 3, one end of the first lock portion 4 is fixedly connected to the first seat body 3 by a fastener, and the other end of the first lock portion 4 serves as a locking portion. In the present embodiment, the bottom of the table top 1 is provided with a third seat body 13 for mounting the flipping portion 5, so that the flipping portion 5 and the first lock portion 4 are at a same height and on a same straight line; and one end of the flipping portion 5 is rotatably connected to the third seat body 13, and the other end is provided with a connection portion 6. In the present embodiment, a base 20 is provided between the flipping portion 5 and the third seat body 13, the base 20 is fixedly connected to the third seat body 13 by a fastener, and one end of the base 20 is hinged with the flipping portion 5 by a shaft body, so that the flipping portion 5 can be flipped back and forth around the base 20. The connection portion 6 comprises a first portion 61 and a second portion 62; the first portion 61 comprises two first rod bodies 611 arranged along the length direction of the first seat body 3 or the second seat body 9, the two first rod bodies 611 are arranged opposite and spaced apart, and end portions of the two first rod bodies 611 are connected to the flipping portion 5; the second portion 62 comprises two second rod bodies 621 arranged along the length direction of the first seat body 3 or the second seat body 9, the two second rod bodies 621 are arranged opposite and spaced apart, and end portions of the first rod bodies 611 and the second rod bodies 621 are arranged parallel to each other and overlapped to form an overlapping portion; the overlapping portion is sheathed with a spring 8; opposite end portions of the first rod body 611 and the second rod body 621 are both formed with a limiting portion 63 limiting the spring 8, so that an elastic connection is formed between the first portion 61 and the second portion 62; and the second lock portion 7 is arranged between the two second rod bodies 621. In the present embodiment, the locking portion of the first lock portion 4 forms a hook-shaped end, and an abutting portion of the second lock portion 7 is a cross rod-shaped end, both ends of the cross rod-shaped structure are connected between the two second rod bodies 621, and the cross rod-shaped end and the hook-shaped end form a hooked connection to achieve locking.

When the flipping portion 5 is flipped towards the first seat body 3, the second portion 62 and the first portion 61 both are flipped with the flipping portion 5, in this case, the second lock portion 7 on the second portion 62 is flipped to the first lock portion 4, and in this case, the second lock portion 7 and the first lock portion 4 are on a same horizontal plane but have a certain distance. Then, the flipping portion 5 is flipped towards the third seat body 13, that is, the flipping portion is flipped towards an opposite direction of the first lock portion 4, the second portion 62 and the first portion 61 together are driven by the flipping portion 5 to move towards the third seat body 13, the second lock portion 7 also moves therewith, and the second lock portion 7 moves to form a hooked connection with the first lock portion 4. In this case, the flipping portion 5 continues to be flipped towards the third seat body 13. Due to the elastic connection between the second portion 62 and the first portion 61, the second portion 62 and the first portion 61 are elastically extended, and the second lock portion 7 is tensioned under an elastic action, so that a stable locking is formed between the second lock portion 7 and the first lock portion 4 under an elastic acting force. When unlocking is required, the flipping portion 5 only needs to be flipped towards a direction of the first seat body 3, and the flipping portion 5 drives the second portion 62 and the first portion 61 to move towards the first seat body 3 until the second portion 62 moves until the second lock portion 7 loses the elastic acting force. In this case, the second lock portion 7 may be easily detached from the first lock portion 4 to complete the unlocking. The elastic connection has the advantages of enabling the first lock portion 4 and the second lock portion 7 to be in a stable locking connection under the action of an elastic tensioning force, and enabling the first seat body 3 and the third seat body 13 or the bottom of the table top 1 to form an elastic connection, so that when the table legs 2 move together with the first seat bodies 3 relative to the second seat bodies 9, the elastic tensioning force always pulls the first seat body 3 and the third seat body 13 between each other. That is, when the table legs 2 move or dislocate relative to the table top 1 during long-term use, the elastic connection enables the table legs 2 to still maintain a stable fixation relationship with the table top 1, and the table legs 2 are always elastically tensioned, so that the table legs 2 do not move all the way to detachable from the table top 1.

It should be noted that when the flipping portion 5 is flipped to be in a locked state, a hinged point of the first portion 61 and the flipping portion 5 and a locking point of the two lock portions are on a same horizontal straight line, or the hinged point is in a lower position relative to the locking point, and a certain snap-fit structure is formed between the flipping portion 5 and the base 20, so that when in the locked state, the flipping portion 5 will not be accidentally flipped by being pulled by the elastic tensioning force in a reverse direction which loosens the locking between the second lock portion 7 and the first lock portion 4, and such accident can be avoided as long as the flipping portion 5 can be stably flipped into a snap fit with the base 20. When the unlocking is required, the flipping portion 5 can be easily flipped by manually applying a slight force to the flipping portion 5 to release snap fit between the flipping portion 5 and the base 20. The snap-fit structure may be, for example, obtained by providing a cross rod on an inner wall of the flipping portion 5, providing a recessed area at a middle position of the cross rod, and providing a protrusion at a corresponding position on the base 20, and rotating the flipping portion 5 to snap the protrusion into the recessed area to form the snap fit between the flipping portion 5 and the base 20. This is of course only one of snap-fit structure designs, and the present invention is not limited to the above-mentioned snap-fit structure. Any snap-fit structure which enables the flipping portion 5 to be released from the base 20 only by an external force is within the scope of the present invention.

A reinforcing support portion 12 is provided between the table leg 2 and the first seat body 3. In the present embodiment, the reinforcing support portion 12 is of a strip-shaped or tubular structure, and one end of the reinforcing support portion 12 is connected to the table leg 2 or is integrated with the table leg 2, a connection point between the table leg 2 and the reinforcing support portion 12 is at a certain distance from a connection point between the table leg 2 and the first seat body 3, and the other end is connected to the first seat body 3 away from the root portion of the table leg 2, so that a triangular structure is formed among the reinforcing support portion 12, the first seat body 3 and the table leg 2; and the third seat body 13 is arranged close to the reinforcing support portion 12, so that the locking mechanism is arranged close to the reinforcing support portion 12, and finally so that a fixing point of the locking mechanism, the reinforcing support portion 12 and the first seat body 3 is on a same horizontal straight line as a fixing point of the root portion of the table leg 2 and the first seat body 3, so that the table leg 2 together with the first seat 3 can be more stably connected to the bottom of the table top 1.

In the present embodiment, since a top end of the table leg 2 is inclined outwards and the reinforcing support portion 12 is also inclined, the locking mechanism is very close to a connection point between and the reinforcing support portion 12 and the first seat body 3; therefore, during use of the table top 1, a locking force of the locking mechanism is balanced with an outward acting force of the table leg 2, that is, the locking mechanism can be elastically tensioned to act on the table leg 2 at all times to prevent the table leg 2 from detaching from the bottom of the table top 1. It should be noted that due to the spring 8 of the locking mechanism, it does not matter even if there is a small relative displacement between the first seat body 3 and the second seat body 9. The elastic connection always forms the tensioning force to pull the first seat body 3, resulting in good stability between the table top 1 and the table legs 2 without shaking between the table top 1 and the table legs 2 in this case. In addition, a spring 8 with a larger elastic coefficient may be used, resulting in a greater elastic tensioning force, and better stability between the table legs 2 and the table top 1.

In the present embodiment, both the first seat body 3 and the second seat body 9 are an elongated plate-like structure, the dovetail groove 10 and the guide rail 11 are also relatively arranged along a length direction of the elongated plate-like structure, and an outer diameter of end portions of the table leg 2 and the reinforcing support portion 12 is equal to or smaller than a width of the first seat body 3, so that the first seat body 3 can still form a stable connection with the second seat body 9 under the action of the table leg 2.

Preferably, a lower end of the table leg 2 is provided with a foot pad 14, a center of a surface of the lower end of the table leg 2 is provided with a screw hole, a stud at one end of the foot pad 14 is screwed into the screw hole, and the other end is in contact with the ground as a support end. A distance between the support end and a top of the table leg 2 is adjusted by rotating the foot pad 14, so that a height of the table top 1 is adjustable; and the support end is provided with an anti-slip texture 15 on a periphery thereof to facilitate rotation.
