The middle of the straight table leg is drilled, a rotating pin is inserted into the hole and is in clearance fit with the hole, the rotating pin can rotate in the hole, and one end, inserted into the straight table leg, of the rotating pin is axially positioned by a spring retainer ring. The big end of the rotating pin is drilled with a unthreaded hole, the axis of the unthreaded hole is vertical to the axis of the rotating pin, and the unthreaded hole is in clearance fit with the screw rod. The screw rod is composed of a threaded rod part and a head part, the threaded rod part is provided with threads, and the screw rod is matched with the threaded hole of the threaded pin. The head of the screw is designed with a flange, and the flange is contacted with the end face of the unthreaded hole of the rotating pin to realize the axial positioning of the screw. The screw rod passes through a smooth hole on the rotating pin and a spring to be matched with the thread in the threaded pin.
Further, the large diameter end of the rotation pin and the large diameter end of the screw pin and the screw rod fitted into them are disposed at one side of the table leg and the lever.
When the head of the screw rod is rotated clockwise, the threaded pin moves axially relative to the screw rod to compress the spring, the distance between the upper end of the lever and the straight table leg is reduced, the lever rotates around the rivet, the lower end of the lever rotates downwards, and the vertical length of the table leg is increased. Otherwise, the legs are shortened. When the ground is uneven, the length of the desk legs can be further adjusted by rotating the head of the screw rod, so that the desk is prevented from shaking.
