Since the lead screw 1 is threaded onto the lifting block 13 and the limiting post 15 passes through the lifting block 13, the rotation of the lifting block 13 is restricted, so that it can only move up and down along the axis of the lead screw 22. The position of the lifting block 13 in the adjusting frame 1 can be adjusted by rotating the knob 12. At this time, the reinforcing diagonal bar 16 on one side of the vertical plate 1 is connected to the support plate 2 to enhance the stability of the vertical plate 1.
