A knob is rotatably installed outside the side plate, and the rotating shaft of the knob is fixedly connected with the rotating shaft of the screw rod. Rotating the knob causes the threaded screw and the screw rod to mesh and rotate, thereby causing the threaded screw to drive the L-shaped plate to move downward. Through the side edge driving mode, the top of the electrical cabinet is fixed by extrusion. It is relatively simple and does not need to consider the height of the electrical cabinet. In addition, the existing protection device has the following disadvantages in use:
