In other embodiments, the supporting portion 303 may have other shapes, and may function as a supporting point, such as a convex arc, a sharp fulcrum, or the like.

In some embodiments, the width dimension of the drive end 400 of the wrench 4 is made larger than the width dimension of the mounting groove 302. This prevents the wrench 4 from falling off. In this embodiment, a connecting plate is connected to the inner wall of the upper end of the first pipe 301, the bottom of the connecting plate is connected to the upper end of the air spring 5, a central hole extending upwards from the control valve 500 of the air spring 5 is provided on the connecting plate, and the connecting plate is connected to the cross beam 100 through four bolts; two blocks extending outwards are arranged on two sides of the driving end 400 of the wrench 4, the driving end 400 of the wrench 4 penetrates through a gap between two bolts, and the blocks on two sides of the driving end 400 of the wrench 4 are limited by the two bolts to prevent the driving end 400 from being separated or deviated.

In some embodiments, to increase the load-bearing capacity of the lifting table, a locking device is connected to the lifting column 3, which locking device is used to lock the first tube 301 and the second tube 300 of the lifting column 3. That is, when the lifting column 3 is unfolded, the locking device locks the first pipe fitting 301 and the second pipe fitting 300 of the lifting column 3, so as to avoid the first pipe fitting 301 and the second pipe fitting 300 from being relatively contracted due to bearing. In this embodiment, as shown in fig. 2, 3 and 5, a nut seat 600 is welded on the second pipe 300 of the lifting column 3, and a locking screw 6 is screwed on the nut seat 600, and a free end of the locking screw 6 can pass through the second pipe 300 to abut against the outer side wall of the first pipe 301. By rotating the locking screw 6, the free end of the locking screw 6 can be made to abut against or loosen the outer side wall of the first tube 301.

In this embodiment, an elastic sliding seat 7 is connected in the second pipe fitting 300, and the inner wall of the central hole of the sliding seat 7 is in sliding fit with the outer side wall of the first pipe fitting 301; further, in order to make the locking of the first pipe 301 more firm and stable and to avoid the loss of the locking screw 6 to the first pipe 301, as shown in fig. 3 and 8, a plurality of through holes 701 communicating with the central hole of the sliding seat 7 and penetrating the free end of the sliding seat 7 are provided in the circumferential direction of the sliding seat 7; the free end of the locking screw 6 abuts against the outer side wall of the sliding seat 7 between two adjacent through holes 701. A positioning groove 702 which is concave and is used for the free end of the locking screw 6 to prop against and position is arranged on the outer side wall of the sliding seat 7 between two adjacent through holes 701. The free end of the locking screw 6 is received and positioned in the positioning groove 702. Rotating the locking screw 6 can make the free end of the locking screw 6 push one of the outer side walls of the sliding seat 7 to shrink inwards and prop against the first pipe 301, so as to increase the locking force of the first pipe 301 and avoid the free end of the locking screw 6 from damaging or scratching the outer side wall of the first pipe 301. In this embodiment, the sliding seat 7 is an elastic plastic member, and is mounted by clamping the clamping buckle 700 on the outer side wall with the clamping hole on the second pipe 300; the four through holes 701 are arranged on the sliding seat 7 and are distributed at four corners of the sliding seat 7, so that the sliding seat 7 part between two adjacent through holes 701 has better elasticity, and the rotation of the locking screw 6 is more labor-saving.
