[0056] According to the foolproof detection port of the door cover, the straight plate 23 of the foolproof component of the contact component 2 is fixedly installed on the outside of the side plate 21 facing the foolproof detection port of the door cover. The side plate 21 drives the locking component's insert block 210 to move into the straight hole 25. The insert block 210 contacts the inclined surface of the lock plate 24 and pushes the lock plate 24 to move outward. The insert block 210 continues to move downward. When the insertion hole 28 moves to face the lock plate 24, the restoring force of the spring 27 drives the lock plate 24 to move. The lock plate 24 is inserted into the insertion hole 28. The lock plate 24 and the insertion hole 28 cooperate to lock the insert block 210, ensuring the stability of the side plate 21. The square frame 55 drives the insert block 210 to move, the insert block 210 drives the side plate 21 to move, and the side plate 21 activates the foolproof mechanism. The straight plate 23 of the component moves, which drives the pressure sensor 26 to move. The pressure sensor 26 drives the anti-foolproof plug 22 to move. When the anti-foolproof plug 22 is inserted into the anti-foolproof detection port of the door cover, the pressure sensor 26 has no detection value, indicating that the control system has not received a signal. The alarm device does not react, and the alarm device can be selected as an audible and visual alarm, indicating that the door cover is assembled correctly. The side plate 21 continues to move, and the four sets of side plates 21 limit the door cover to realize the detection of the door cover. When the anti-foolproof plug 22 contacts the door cover, the pressure sensor 26 has a detection value, indicating that the door cover is assembled incorrectly, which facilitates accurate detection. This indicates that the control system has received a warning signal, and the control system controls the alarm device to issue an audible and visual warning.
