C. referring to fig. 22, under a locking instruction of the control system, the motor 85 drives the scroll rod 851 to rotate, so as to drive the pinion set 84 and then the bull gear 83 to rotate clockwise, after the bull gear 83 rotates by an angle B, the dial 831 of the bull gear drags the sector gear 82 to rotate clockwise, so that the sector gear 82 drags the main bolt 20 to slide out of the main lock hole 131, and meanwhile, the main bolt 20 drives the two sets of auxiliary bolts 30 to integrally extend out of the corresponding auxiliary bolt holes 133 through the two world poles, so as to be locked synchronously. The motor 85 is stopped until the second inductive switch 15 is triggered, i.e., locked.

D. Referring to fig. 23, when the control system receives an unlocking instruction, the motor 85 drives the scroll bar 851 to rotate reversely, so as to drive the pinion gear to rotate reversely, and then drive the bull gear 83 to rotate counterclockwise, after the bull gear 83 rotates by an angle a, the dial 831 drags the sector gear 82 to rotate counterclockwise together, the sector gear 82 drives the main bolt 20 to retract into the main lock hole 131, and meanwhile, the main bolt 20 drives the two sets of auxiliary bolts 30 to retract into the corresponding auxiliary bolt holes 133 integrally through the two world poles, so as to unlock synchronously. The motor 85 is stopped until the third inductive switch 16 is triggered, i.e. the unlocking is completed. When the main bolt 20 is unlocked, the latch bolt hooking assembly 86 is driven to hook the buckling platform 41 of the latch bolt 40, the latch bolt 40 is pulled downwards, the latch bolt 40 retracts into the latch bolt hole 132, and the greater the retraction amplitude of the latch bolt 40 is, the greater the elastic potential energy stored by the latch bolt ejecting assembly 87 is. When the lower end of the latch tongue 40 touches the first inductive switch 43 again, the motor 85 rotates forward to drive the large gear 83 to return clockwise, the shifting block 831 touches the latch tongue hooking component 86 in the returning process to enable the latch tongue hooking component 86 to be unhooked from the latch tongue 40, the elastic potential energy of the latch tongue popping component 87 is converted into power, the latch tongue 40 is popped out instantly, and the normal state of the lock is recovered, which is shown in fig. 24.

When the electric lock body is powered off, the functions of the traditional mechanical lock are kept. Manual keys are required to unlock the lock from the outside of the door or to rotate the handle to lock and unlock the lock from the inside of the door.

E. The manual locking process is as follows: the lock core 70 is rotated to drive the lock core gear 81 to rotate, and the sector gear 82 rotates clockwise by an angle a', so that the main bolt toggle part 823 on the sector gear 82 slides from the unlocking position S1 of the oblique lock slot 21 to the upper locking position S2, the main bolt 20 extends out of the main lock hole 131, and simultaneously the two sets of auxiliary bolts 30 are driven by the two ground rods to integrally extend out of the corresponding auxiliary bolt holes 133 to be locked synchronously.

F. the manual unlocking process is as follows: when the key cylinder 70 is rotated to drive the key cylinder gear 81 to rotate, and the sector gear 82 rotates counterclockwise by an angle a', the main bolt striking part 823 on the sector gear 82 can slide from the upper locking position S2 to the unlocking position S1 of the oblique lock slot 21, and the main bolt 20 retracts into the hole of the main bolt 20, so as to unlock the lock. When the main bolt 20 is unlocked, the two sets of auxiliary bolts 30 are driven by the two ground rods to integrally retract into the corresponding auxiliary bolt holes 133, so that the lock is synchronously unlocked. Main bolt 20 also drives latch bolt hooking assembly 86 to hook catch 41 of latch bolt 40, and pulls latch bolt 40 downward, so that latch bolt 40 retracts into latch bolt hole 132, and latch bolt 40 is also in the unlocked state.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the technical scope of the present invention, so that any slight modifications, equivalent changes and modifications made by the technical spirit of the present invention to the above embodiments are all within the scope of the technical solution of the present invention.
