Specifically, the clutch 51 includes a power element 511, a screw 512 and a sleeve 513, the power element 511 being adapted to receive a signal from the control module and to power the extension or retraction of the telescopic pin 518; the power element 511 in this embodiment is specifically a servo motor controlled by a control module. The screw 512 is connected with the power output end of the power element 511 and is suitable for forward or reverse rotation under the drive of the power element 511; the threaded sleeve 513 is screwed on the periphery of the screw 512, and one end of the threaded sleeve is connected with the telescopic pin 518, so that the telescopic pin 518 is driven to extend or retract when the screw 512 rotates.
As an improved embodiment of the clutch 51, the threaded sleeve 513 is connected to the telescopic pin 518 by a force accumulating structure adapted to store kinetic energy of the outward movement of the telescopic pin 518 when the threaded sleeve 513 pushes the telescopic pin 518 to extend outward without the telescopic pin 518 being aligned with the locking hole 52. Specifically, the force accumulating structure includes a push rod 514 and a first elastic element 515, one end of the push rod 514 is fixedly connected with a telescopic pin 518, and the other end extends into the screw sleeve 513 and is installed in a telescopic manner relative to the screw sleeve 513; the first resilient element 515 is mounted between the telescoping pin 518 and the threaded sleeve 513. An end cover 516 is mounted at the end, connected with the push rod 514, of the threaded sleeve 513, and a flange 514a suitable for being abutted against the inner wall of the end cover 516 is arranged on the push rod 514. After the telescopic pin 518 and the locking hole 52 are aligned by rotating the second rotating assembly, the telescopic pin 518 is pushed out and inserted into the locking hole 52 by the first elastic member 515, and the engaging action of the clutch structure 5 is completed. Therefore, the structure can ensure that the telescopic pin 518 can be finally inserted into the locking hole 52 by rotating the second rotating part 22 no matter whether the telescopic pin 518 is aligned with the locking hole 52 or not, thereby avoiding the failure of the clutch 51; on the other hand, the above structure can also enable an operator to unlock the control module first, enable the telescopic pin 518 in the clutch 51 to extend, and then judge whether the telescopic pin 518 extends into the locking hole 52 through rotation sensing, so that the operation mode is beneficial to quick unlocking, the time spent for aligning the relative positions of the telescopic pin 518 and the locking hole 52 before unlocking is avoided, and the operation convenience of the lock cylinder is improved.
As a further improved embodiment of the clutch 51, the clutch 51 further comprises a second elastic element 517 mounted between the screw sleeve 513 and the inner wall of the clutch 51, adapted to provide a thrust force for the outward movement of the screw sleeve 513. When the screw 512 drives the sleeve 513 to move to the innermost position, the threads of the sleeve 513 and the screw 512 are used up and tripped, and the screw 512 idles when rotating again. Then, when the screw rod 512 is rotated in the reverse direction again to drive the screw sleeve 513 to move outwards, the screw sleeve 513 cannot form threaded fit with the screw rod 512 due to the fact that threads are used up, at this time, the second elastic element 517 acts to push the screw sleeve 513 to move outwards, and initial force required for entering threaded fit between the screw sleeve 513 and the screw rod 512 is given, so that the screw sleeve 513 cannot return. Thus, this can ensure that the disengaging and engaging actions of the clutch 51 can be repeatedly performed, ensuring that the clutch 51 is not disabled for a long period of use.
The first resilient element 515 and the second resilient element 517 are both circular coil springs in this embodiment.
As an improved embodiment of the lock cylinder, the outer handle assembly 1 can slide in a locking manner along the axial direction of the linkage; the first and second rotating parts 21, 22 are lockable slidable along the auxiliary. This ensures that the distance between the outer handle assembly 1 and the inner handle assembly 2 is adjustable, thereby accommodating door bodies of different thicknesses.
As shown in fig. 6 and 7, in order to achieve the above action, the outer handle assembly 1 is provided with a threaded hole which is not parallel to the linkage, the threaded hole is internally and spirally connected with a jackscrew 9, the relative position between the outer handle assembly 1 and the linkage can be locked by screwing the jackscrew 9, and the locking form can be released by unscrewing the jackscrew 9, so that the outer handle assembly 1 can slide along the linkage. The same reason is that the locking or release of the relative position between the second rotating part 22 and the auxiliary part is also achieved between the second rotating part 22 and the auxiliary part by means of the jackscrew 9. On the other hand, in order to ensure the anti-theft performance of the outer handle assembly 1, the jackscrew 9 on the outer handle assembly 1 also has a slope towards the door body direction, and a common screwdriver cannot operate the jackscrew 9 after the lock cylinder is mounted on the door body, so that the aim of removing the outer handle by removing the jackscrew 9 on the outer handle assembly 1 by a thief is avoided.
As a specific embodiment of the lock cylinder structure, the information collecting module includes one or more of a fingerprint identification device 11, a password input device 12 and a face identification device. The external structure of the fingerprint recognition device 11 is shown in fig. 3, and the external structure of the password input device 12 is shown in fig. 4.

Since this embodiment includes the lock cylinder structure described in embodiment 1, all the technical effects brought about by embodiment 1 are also achieved.
Example 3:
the embodiment is an anti-theft door, comprising a door body, wherein the door body is provided with an intelligent door lock in embodiment 2. Since this embodiment includes the intelligent door lock described in embodiment 2, all the technical effects brought by embodiment 2 are also achieved.
