The working principle of the embodiment is as follows:

firstly, unlocking action:

firstly, a user carries out identity recognition through a control instruction input module, when the main control chip judges that identity information is wrong, the motor is in a non-working rotating state, and because the movable lock pin 41 and the locking clamping groove 31 are in a separated state, when the handle a is manually driven to rotate in the unlocking direction, the input rotating body 2 idles relative to the output rotating body 3, and the lock body cannot be driven to be unlocked. If the master control chip judges that the user identity information is correct, the master control chip controls the master control motor 4233 to rotate forwards, the master control motor 4233 drives the master control rotating shaft 42311 to rotate through the master control transmission mechanism 4234, the master control stirring rod 423111 on the master control rotating shaft 42311 can drive the master control spiral spring 42313 to extend along the axial direction and push the master control push plate 42312 to move towards the advancing direction, meanwhile, the push block guide rod 4211 and the arc-shaped push block 421 are driven to move towards the direction close to the movable lock pin 41 and push the movable lock pin 41 to be clamped into the locking clamping groove 31, when the common contact e moves to be triggered by the unlocking contact f, the master control chip receives the unlocking signal fed back by the unlocking contact f to control the motor to stop working forwards, the master control chip controls the output prompting module to output a prompting signal so as to prompt a user to unlock, when the handle a is manually driven to rotate towards the unlocking direction, the input rotator 2 and the output, when the unlocking is completed, the induction magnet on the input rotating body 2 can be attracted with the corresponding unlocking detection switch and feeds back an unlocking completion signal to the main control chip, the main control chip controls the motor to reversely work according to the unlocking completion signal, at the moment, the main control spiral spring 42313 is axially shortened in the movement process, the main control push plate 42312 is pushed by the unlocking return spring 4235 to retreat backwards, and when the movement of the common contact e is triggered by the unlocking return contact g, the main control chip controls the motor to stop reversely work, so that a complete unlocking action is completed. The working principle of the standby unlocking part is similar to that of the main control unlocking part, so that the mechanical lock cylinder does not need to be assembled to serve as standby emergency unlocking, and the safety level of the anti-theft lock can be greatly improved.

Secondly, locking action:

when the anti-theft execution device performs locking action, the handle a drives the input rotating body 2 to rotate in the direction opposite to the unlocking direction, one limiting end 511 of the arc-shaped notch 51 on the input rotating body 2 can synchronously push the arc-shaped flange 52 and the output rotating body 3 to rotate in the unlocking direction, and therefore the output rotating body 3 can drive the lock body to complete locking action.
