The frame rises, the sliding block rises along the sliding track, and when it rises to a suitable height, the drive motor is controlled to stop rotating. Similarly, when the height of the control table is lowered, the drive motor is controlled to reverse, which drives the driving wheel to reverse and the driven wheel to rotate forward. Then the lead screw rotates forward to drive the lifting frame to descend, and the sliding block rises along the sliding track. When it rises to a suitable height, the driving motor is controlled to stop rotating. The fixed reinforcing plate is a right-angle triangular plate. There are at least four sets of fixed reinforcing plates, and The distance between each two fixed reinforcing plates is equal, which can maintain the stability of the table and solve the problem that the height of the office desk itself is different for people of different heights. Although many desks can be adjusted in height, the existing When the desk is adjusted in height, the adjustment process is complicated, resulting in inconvenient adjustment.
