The surface of the limiting mirror panel 8 is fixed to the top of the support rod, and the driving main handle 6 is located on one side of the lifting plate 4 which is convenient for easy operation. After the weldment is placed above the lifting plate 4, the position of the limiting mirror panel 8 can be adjusted by rotating the driving main handle 6.
