The vertical rod can be fixed by the cooperation between the positioning rod and the positioning hole.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This utility model, by setting up a base, box body, support legs, placement platform, lifting device, fixing mechanism, and auxiliary mechanism, first adjusts the placement platform according to the user's height. Then, the lifting device is activated, the servo motor rotates, the servo motor drives the second gear to rotate, the second gear drives the lead screw to rotate, and the lead screw, through a threaded connection, drives the vertical rod to move. The vertical rod then moves the placement platform, moving the limiting plate out. With the help of a spring, the positioning rod moves, moving to the inner cavity of the vertical rod's positioning port, thus fixing the vertical rod. This solves the problem in existing technologies where most double-layer workbenches lack height adjustment functionality, cannot be adjusted according to the user's height, causing inconvenience when the user retrieves items.
