The sliding rod 952 passes through the elongated hole 913 and is slidably connected with the elongated hole 913, and the limiting plate 93 is limited between the limiting heads 951 and the limiting rings 953.

Because of the existence of the limit head 951, the section of the end of the limit head 951 near the sliding rod 952 is larger than the section of the elongated hole 913, so that the end of the limit head 951 far from the second bending head 932 is abutted against the side of the sliding slat 91 near the second bending head 932, and at this time, the limit slat 93 has a certain elasticity due to being abutted and bent; when the position of the limiting head 951 corresponds to that of the clamping hole 914, under the reset action of the limiting plate strip 93, one end of the limiting head 951, which is close to the sliding rod 952, is clamped into the clamping hole 914, and locking of the unfolded table leg 92 is completed.

When the end of the limiting head 951 close to the sliding rod 952 is clamped into the clamping hole 914, the limiting plate 93 is pressed in the direction away from the sliding plate strip 91, so that the limiting head 951 is separated from the clamping hole 914, and the limiting head 951 is abutted against one side of the sliding plate strip 91 close to the second bending head 932 by moving the table leg 92, so that unlocking of the unfolded table leg 92 is completed; the limit ring 953 effectively reduces the falling of the sliding rod 952 from the elongated hole 913.

Referring to fig. 8 and 11, a supporting strip 96 is fixedly connected to one side of the table leg 92, which is close to the table board 1, and the connection position of the supporting strip 96 and the table leg 92 is positioned above the connection position of the limiting strip 93 and the table leg 92; one side of the transverse reinforcing rib 23 far away from the table plate 1 and one end of the transverse reinforcing rib 23 far away from the connecting plate 3 are fixedly connected with a connecting seat 97, an extending part 971 perpendicular to the table plate 1 is bent on the connecting seat 97, one end of the supporting lath 96 far away from the table leg 92 is bent with a mounting part 961, and two mounting parts 961 on the same connecting frame 2 are rotationally connected with the extending part 971. The supporting strips 96 serve to strengthen the supporting legs 92, and the two supporting strips 96 can support each other due to the rotational connection between the two mounting portions 961 and the extending portions 971 on the same connecting frame 2, so that the overall stability of the legs 92 is improved.

Referring to fig. 13, the table leg 92 is a hollow outer tube leg, and an inner tube leg 98 for supporting the ground is slidably connected in the outer tube leg, thereby realizing the telescopic extension of the table leg 92. A limit sleeve 921 is fixedly sleeved at one end of the outer pin, which is far away from the sliding strip 91, a square groove matched with the outer pin is formed in one end of the limit sleeve 921, which is close to the outer pin, the limit sleeve 921 is fixedly sleeved on the outer pin through the square groove, and the inner side wall of the limit sleeve 921 is positioned in the hollow part of the outer pin; the peripheral side of the inner pin 98 abuts against the inner side wall of the stopper 921. Therefore, in the process of sliding the inner pin 98 in the outer pin, the limiting sleeve 921 can limit the shaking of the inner pin 98, so that the sliding connection between the inner pin 98 and the outer pin is more stable; the end of the inner pin 98 extending out of the outer pin is fixedly sleeved with a pin sleeve 981 for supporting the ground.

The inner pins 98 are solid tubes for locking the extended legs 92; a V-shaped elastic sheet 982 is arranged in the cavity of the inner pin 98, a locking hole is formed in one side of the outer pin, which is close to the connecting strip, and is adjacent to the limiting sleeve 921, an extension hole communicated with the cavity is formed in one side of the inner pin 98, which is close to the connecting strip, a locking key 983 corresponding to the position of the extension hole is fixedly connected to one end of one side of the elastic sheet 982, and one end, which is far away from the elastic sheet 982, of the locking key 983 penetrates through the extension hole and extends out of the inner pin 98; when the extending hole is not communicated with the locking hole, one end of the locking key 983, which is far away from the elastic sheet 982, is abutted against the inner side wall of the outer pin, and the elastic sheet 982 is in a compressed state and has an outward tension. When the extending hole corresponds to and is communicated with the locking hole, under the elastic action of the elastic sheet 982, one end of the locking key 983, which is far away from the elastic sheet 982, passes through the locking hole and extends out of the outer tube leg; thereby effecting locking of the extended leg 92.

The foregoing are all preferred embodiments of the present application, and are not intended to limit the scope of the present application in any way, therefore: all equivalent changes in structure, shape and principle of this application should be covered in the protection scope of this application.
