With reference to Fig. 2, on the output shaft of motor 8, be connected with the transmission mechanism that cooperates with clutch device, as shown in the figure, transmission mechanism comprises the gear 14 that is installed on the output shaft of motor 8, the gear spring 15 that is installed in outer lock housing 2 and Rotating block 16, one end of gear spring 15 is stuck between the two protruding teeth of gear 14, one end of rotating block 16 is pivotally connected in outer lock housing 2, and the other end is connected with gear spring 15. When the motor 8 rotates, one end of the gear spring 15 moves between the teeth of the gear 14, and is twisted under the action of the gear, and the rotating block 16 can rotate around the pivot on the outer lock housing 2 under the elastic force of the gear spring 15 .

A knob 11 is installed on the inner lock case 1, and the knob 11 on the inner lock case 1 is provided for indoor opening or locking. A rotating piece 12 is connected between the knob 11 and the square shaft positioning block 10, and the rotating piece 12 is connected with the deadbolt mechanism through a connecting rod 13. When the knob 11 rotates, it can drive the rotating piece 12 to rotate, and the rotating piece 12 drives the connecting rod 13 to move. The connecting rod drives the bolt mechanism to move linearly, so as to achieve the purpose of unlocking or closing the lock.

Referring to Fig. 5, Fig. 6 and Fig. 7, a pin hole 17 is provided on the square shaft positioning block 10 and the toggle block 9, wherein the clutch device includes a square shaft positioning pin 18 installed in the pin hole 17 of the square shaft positioning block 10 , positioning pin spring 19 and the positioning block pin 20 installed in the pin hole 17 of the toggle block 9, the positioning block pin 20 is in contact with the rotating block 16, when the motor 8 rotates and drives the rotating block 16 to rotate, the positioning block pin 20 is affected by The rotating block 16 presses and moves in the pin hole 17 on the toggle block 9, and its other end is then inserted into the pin hole 17 in the square shaft positioning block 10, while the positioning pin spring 19 is compressed, and the square shaft positioning block 17 and the dial The moving block 9 is combined as a whole, and the two can rotate synchronously. After the lock is opened, the motor resets, the gear spring and the rotating block also reset accordingly, and the positioning pin of the square shaft resets under the action of the positioning pin spring, pushing the pin of the positioning block away from the pin hole in the positioning block of the square shaft, so that the positioning block of the square shaft Separated from the toggle block, turning the toggle block at this time cannot drive the square shaft positioning block to rotate synchronously, so the lock cannot be opened.
