The tongue plate 9 rotates clockwise under the action of the tension spring 8, the box cover buckle plate B is drawn out from the tongue part 9-4, and as shown in (d) of fig. 8, the unlocking of the opening cover is completed.

After unlocking, the driving component 5 drives the lock catch shifting block 6 to continue to rotate anticlockwise until the zero position sensor is contacted, and the lock catch shifting block 6 stops rotating and is reset. Here, the setting position of the zero position sensor can be selected according to the internal space, as long as the lock catch shift block 6 and the fitting portion thereof can be in contact therewith within the design stroke. Under the action of the torsion spring 14, the stop part 12-2 of the lock limiting baffle 12 is inserted into the gap between the lock plate 7 and the shell A, namely, the stop part 12-2 is abutted against the lock plane 7-4-2; when the box cover is locked again, the box cover buckling plate B presses the bolt part 9-4 of the bolt plate 9 downwards, the bolt plate 9 rotates anticlockwise under the action of the downward pressing of the box cover buckling plate B, meanwhile, the tension spring 8 drives the locking plate 7 to move anticlockwise, the locking part 7-4 on the locking plate 7 is pressed against the abutting plane 9-3-1 on the bolt plate again, and the bolt plate 9 is locked.
