Through the setting of the locking member 203, the fixing frame 201 is effectively limited on the power system, so that the protective cover 204 hinged on the outer side of the fixing frame 201 can protect the pressure plate on the power system, avoid the wrong command caused by accidental contact with the pressure plate, and avoid the loss caused by accidental contact. The protective cover 204 is made of transparent material, which is convenient for the staff to better view the internal pressure plate through the protective cover 204. The key 205 is threadedly connected to the protective cover 204, which is convenient for opening the protective cover 204 when the pressure plate is abnormal or needs to be adjusted, so that the staff can quickly adjust the pressure plate inside the protective cover 204.

[0050] Preferably, the locking member 203 includes a connecting column 203a which is nested and connected inside the fixed block 202, and a limiting hole 203c is symmetrically provided on the connecting column 203a. A limiting ball 203d is movably nested and installed inside the limiting hole 203c.
