When the breakpoint motor 41 cannot be started, manual locking or unlocking is required, and the mechanical locking process is that when the lock cylinder in the mechanical lock hole 11 of the key is rotated, the middle plate 61 is pressed down first, so that the middle plate 61 moves downward, the third rotating member 64 is driven to rotate clockwise to press the mounting plate 62, and the motor 41 is separated from the tooth part 42;

since the toggle element 44 may be located at any position during power failure, i.e. the straight line of the first swing leg 442 and the second swing leg 441 is not necessarily parallel to the direction of the main bolt 45, at this time, the outer plate 47 cooperates with the stepped structure 443 on the lower surface of the toggle element 44, and the movable window 472 is used to rotate the toggle element 44 to a position where the first swing leg 442 and the second swing leg 441 are located on the horizontal line;

of course, the above-mentioned processes also exist in the motor unlocking or locking process, so that the dial 44 keeps the first swing leg 442 and the second swing leg 441 on a horizontal line parallel to the main bolt 45 before the next operation process, which facilitates the mechanical unlocking or locking process, so that the manual mechanical unlocking is kept in the initial state, and the operation is smoother.

Due to the dislocation structure of the middle plate 61, the inner plate 46 and the outer plate 47, when the lock cylinder continues to rotate, the outer plate 47 is pressed down, so that the limiting columns 463 and the limiting teeth 473 are unlocked;

the lock cylinder continues to rotate, and the second projection 462 of the inner plate 46 is pulled, so that the main bolt 45 is driven to translate along with the inner plate 46 and extend out of the housing 1. The process of sensing the movement of the locking bolt 21 and the inclined locking bolt 31 in the mechanical locking process is the same as the locking process of the motor, and the detailed description is omitted.

The mechanical unlocking process includes rotating the lock cylinder in the opposite direction, shifting the second protrusion 462 to retract the main bolt 45 into the housing 1, continuing to rotate, driving the hook 465 to move downwards, so that the inclined portion 4642 moves downwards to abut against the first cylinder 71, driving the fourth rotating member 7 to rotate anticlockwise, driving the first rotating member 23 to rotate clockwise, and allowing the second rotating member 32 to rotate anticlockwise to release the abutting effect on the inclined bolt 31, so that the inclined bolt 31 can be pushed into the housing 1 against the second torsion spring 312.
