In addition, the first elastic member 52 may be provided as a tension spring or a compression spring.

Referring to fig. 7 to 11, the clutch device 20 includes a motor 21, a first gear 22, a second gear 23, and a first transmission mechanism 24. The first gear 22 is sleeved on the output shaft of the motor 21, and the first gear 22 can rotate relative to the output shaft of the motor 21. A pivot 231 is disposed on the lock case 10, the second gear 23 is sleeved on the pivot 231 to enable the second gear 23 to rotate relative to the lock case 10, and the second gear 23 is engaged with the first gear 22. A second dial 232 is provided on the second gear 23, and the second dial 232 is capable of being inserted into and engaged with the first dial slot 411. The first transmission mechanism 24 is movably arranged on the lock shell 10. The output shaft of the motor 21 is in transmission connection with the first gear 22 through a first transmission mechanism 24, so that the first gear 22 can rotate along with the output shaft of the motor 21, and further the second gear 23 can be driven to rotate. When the first shifting block 31 rotates, the first transmission mechanism 24 can be pushed to act, and when the first transmission mechanism 24 acts, the output shaft of the motor 21 can be separated from the transmission connection with the first gear 22, and at the moment, the first gear 22 does not rotate along with the output shaft of the motor 21.

Specifically, the first transmission mechanism 24 includes a second sliding plate 241, a clutch dial 242, a second elastic member 243, a clutch sleeve 244, and a third elastic member 245. The second sliding plate 241 is slidably disposed on the lock case 10, and the second sliding plate 241 is provided with a hook groove 2411 and a thrust portion 2412 engaged with the first toggle head 31. The lock case 10 is provided with a second mounting post 132, the clutch shift block 242 is sleeved on the second mounting post 132, so that the clutch shift block 242 can rotate relative to the lock case 10, and one end of the clutch shift block 242 is hung in the hook groove 2411.
