The lower end of the connecting plate 152 is perpendicularly and fixedly connected to the lower mounting plate 151, and the upper end is perpendicularly and fixedly connected to the upper mounting plate 153.

[0019] The lower end of the lower mounting plate 151 is provided with a threaded sleeve 12. The threaded sleeve 12 is provided with a threaded through-hole, and the threaded through-hole of the threaded sleeve 12 is in threaded cooperation with the first screw rod 13. The upper end of the first screw rod 13 is connected to the clamping plate 14, and the lower end is connected to the handle 11.

[0020] The upper mounting plate 153 is provided with a lifting mechanism 2. The lifting mechanism 2 includes a lifting sleeve 21, a rotating sleeve 22, a second screw rod and a hinge seat 24. The lower end of the lifting sleeve 21 is fixedly connected to the upper mounting plate 153. The upper end of the lifting sleeve 21 is provided with a guiding hole, and the inner wall of the guiding hole is provided with two symmetrically distributed sliding blocks. The outer wall of the second screw rod is provided with a sliding groove corresponding to the sliding blocks. The lower end of the second screw rod is inserted into the guiding hole of the lifting sleeve 21, and the sliding blocks are placed in the sliding grooves of the second screw rod, and the two are in sliding cooperation.

The upper end of the rotating sleeve 22 is provided with a threaded hole, and the second screw rod is in threaded cooperation with the threaded hole of the rotating sleeve 22. When the rotating sleeve 22 is rotated, the second screw rod can be driven to move up and down along the sliding blocks.

[0022] In an optimized solution, two rotating rods 23 are symmetrically installed on the outer wall of the rotating sleeve 22, which can facilitate the rotation of the rotating sleeve 22.
