The spring 23 will be pulled. When the protective film is subjected to less force, the spring 23 will drive the connecting block 24 to descend, and the connecting block 24 will drive the fixing rod 27 to descend while driving the rotating drum 28 to descend. The outer wall of the rotating drum 28 will still fit the top surface of the protective film to prevent the protective film from being damaged, thereby achieving a protective effect and improving production quality.

The equipment is controlled by the control panel 29, and the lifting mechanism 3 drives the workbench 1 to move up and down. The height of the equipment is adjusted according to the height of the staff to a comfortable height that is convenient for loading and unloading materials, thereby improving comfort and practicality.
