When the motor output shaft rotates clockwise, the left-turn clutch gear 4 will first mesh with the first reduction gear 6, and then the motor output shaft continues to rotate clockwise to drive the first reduction gear 6 to rotate clockwise, and then through the coordinated transmission of all the reduction gears 6, it will drive the main shaft gear 8 to rotate clockwise, and then through the meshing of the main shaft gear 8 with the main gear ring 11, the auxiliary lock housing 1 0 will automatically rotate clockwise, when the motor output shaft rotates counterclockwise, the right-turn clutch gear 3 will first mesh with the first reduction gear 6, and then the motor output shaft continues to rotate counterclockwise to drive the first reduction gear 6 to rotate counterclockwise, and through the coordinated transmission of all reduction gears 6, the main shaft gear 8 will be driven to rotate counterclockwise, and then through the engagement of the main shaft gear 8 with the main gear ring 11, the secondary lock housing 10 will automatically rotate counterclockwise, and the smart lock can thus automatically unlock or lock. When the right-turn clutch gear 3 and the left-turn clutch gear 4 are disengaged from the first reduction gear 6 at the same time, the motor does not interfere with the rotation of the reduction gear 6, and the reduction gear 6 can rotate freely. At this time, manual unlocking of the smart lock can be achieved.
