The collar portion 431 has a groove 434 formed in an outer surface. The sliding rail portion 432 has a limiting groove 435 for the unlocking member 221 to pass through and engage with the unlocking member 221. In the first embodiment, the cross section of the limiting groove 435 is cross-shaped, so that the force generated during rotation can be dispersed to avoid the unlocking member 221 from being damaged, but in other variations, the limiting groove 435 may be polygonal or irregular in shape in cooperation with the unlocking member 221, so long as it is non-circular. In the first embodiment, the second engaging portion 433 of the clutch base 43 is a bump and extends in the direction of the first engaging portion 413, so that the second engaging portion 433 can be engaged with the first engaging portion 413 by means of concave-convex engagement. However, in other variations, the first engaging portion 413 and the second engaging portion 433 may be a bump and a groove, respectively.

Referring to fig. 8, 9 and 10, the clutch seat 43 is movable relative to the rotating seat 41 between an unlocked position (fig. 9) and a non-unlocked position (fig. 10). As shown in fig. 9, when the clutch base 43 is at the unlocking position, the second engaging portion 433 is engaged with the first engaging portion 413, so that the knob 42 can drive the rotating base 41 to rotate and drive the clutch base 43 to drive the lock cylinder 22 to rotate, thereby unlocking. As shown in fig. 10, when the clutch base 43 is in the non-unlocking position, the second engagement portion 433 is disengaged from the first engagement portion 413, and at this time, the knob 42 cannot drive the clutch base 43 to rotate, so that the lock cylinder 22 cannot be rotated.

Referring to fig. 5, 6 and 7, the driving unit 5 is configured to drive the clutch base 43 to move between the unlocking position and the non-unlocking position. The drive unit 5 comprises an elastic member 51, a driver 52, and a battery 53 for supplying power. In the first embodiment, the elastic member 51 is a torsion spring, and has a body 511, and a first arm 512 and a second arm 513 extending from the body 511 and disposed in opposite directions. The first arm 512 is hooked to the groove 434 of the clutch base 43, and the second arm 513 is connected to the driver 52. The driver 52 is used for driving the elastic member 51 to drive the clutch base 43 to move. In the first embodiment, the driver 52 has a telescopic member 521 and a driving member 522 for driving the telescopic member 521 to move in the top-bottom direction Z. The driving member 522 is configured to drive the expansion member 521 up and down by a motor (not shown) and a screw (not shown).

As shown in fig. 9, when the telescopic member 521 is retracted, the elastic member 51 is driven to pivot and the first arm 512 drives the clutch base 43 to move toward the knob 42, and the second engaging portion 433 of the clutch base 43 is engaged with the first engaging portion 413 of the rotating base 41.

As shown in fig. 10, when the expansion member 521 is extended, the elastic member 51 is driven to pivot reversely, the first arm 512 drives the clutch base 43 to move away from the knob 42, and the second engaging portion 433 of the clutch base 43 is disengaged from the first engaging portion 413 of the rotating base 41.

Referring to fig. 5 and 11, the control module 6 is configured to transmit an unlocking command and a locking command to the driving member 522 of the driver 52 to drive the clutch seat 43 to move to the unlocking position so as to unlock and lock. The control module 6 is used for sensing and receiving the identification data of the card 300, and controlling the driving member 522. In the first embodiment, the control module 6 communicates with the card 300 using radio frequency identification (Radio Frequency Identification, abbreviated as RFID).

Preferably, when the control module 6 receives the identification data of the card 300, the unlocking command is transmitted to the driving member 522 to drive the clutch seat 43 to move to the unlocking position and stay for a preset time, which is 5 seconds in the first embodiment. When the clutch seat 43 is at the unlocking position for more than the preset time, the control module 6 transmits the locking command to the driving member 522 to drive the clutch seat 43 to move to the non-unlocking position. Therefore, when the card 300 is unlocked by sensing, if the knob 42 is not turned for opening the door for more than the preset time, the clutch seat 43 will move to the unlocking position for locking automatically, so that the security is high.

In addition, the first embodiment can also communicate wirelessly with a mobile device (not shown), such as a smart phone, using Bluetooth (Bluetooth) technology. The mobile device is configured to send an unlocking signal to the control module 6, so that the control module 6 transmits the unlocking command to the driver 52 to drive the clutch seat 43 to move, thereby having the unlocking function.
