The above structural design enables the bracket 1 to stably support the connected structure, and the positioning bolts 2 can stably install the counterweight block 5.

[0022] The top view shape of the mounting slot 4 is "U"-shaped, and the mounting slot 4 is symmetrically distributed about the center of the counterweight 5. The above structural design enables the counterweight 5 to be conveniently installed and separated through the mounting slot 4 and the positioning bolt 2.

[0023] The vertical threaded rod 7 is threadedly connected to the movable plate 8. The vertical threaded rod 7 is symmetrically distributed about the center of the movable plate 8. The above structural design enables the vertical threaded rod 7 to stably drive the movable plate 8 to move vertically by utilizing the threaded connection relationship when rotating.
