as a specific embodiment of the clutch structure 5, as shown in fig. 5, the clutch structure 5 includes a lock hole 52 and a clutch 51, the lock hole 52 is provided on an outer wall of the second rotating member 22; a retractable pin 518 is mounted in the clutch 51 to be extendable and retractable under the control of the control module, said retractable pin 518 being adapted to be extended and inserted into the locking hole 52 when the clutch mechanism 5 is engaged, or retracted into the clutch 51 when the clutch mechanism 5 is disengaged. After the clutch structure 5 is designed into the above form, compared with the electromagnetic clutch 51 and the friction clutch 51, the pin-hole clutch 51 can resist larger external force, improve the breaking difficulty of the lock cylinder, and avoid the accidental failure of the clutch structure 5.

in particular, the clutch 51 comprises a power element 511, a screw 512 and a threaded 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 the control module. The screw 512 is connected with the power output end of the power element 511 and is suitable for being driven by the power element 511 to rotate in the forward direction or the reverse direction; the threaded sleeve 513 is threaded on the outer periphery of the screw 512, and has one end connected to the retractable pin 518, and is adapted to drive the retractable pin 518 to extend or retract when the screw 512 rotates.

When the screw 512 drives the threaded sleeve 513 to move to the innermost position, the threads of the threaded sleeve 513 and the screw 512 are used up and are disengaged, and the screw 512 rotates again and idles. Then, when the screw 512 rotates reversely again to drive the screw 513 to move outwards, the screw 513 cannot form a thread fit with the screw 512 due to the exhausted thread, and at this time, the second elastic element 517 acts to push the screw 513 to move outwards, so as to provide an initial force required for entering the thread fit between the screw 513 and the screw 512, and prevent the screw 513 from returning. Thus, this ensures that the disengagement and engagement of the clutch 51 can be repeatedly performed, ensuring that the clutch 51 does not fail over long periods of use.

The first and second elastic elements 515, 517 are both circular coil springs in this embodiment.

As a modified embodiment of the lock cylinder, the external handle assembly 1 can be lockably slid along the axial direction of the linkage; the first and second rotation members 21, 22 are lockably slidable along the auxiliary element. This can guarantee that the distance between outer handle component 1 and the interior handle component 2 is adjustable, and then adapts to the door body of different thickness.

as shown in fig. 6 and 7, in order to realize the above actions, the external handle assembly 1 is provided with a threaded hole which is not parallel to the linkage member, a jackscrew 9 is screwed in the threaded hole, the relative position between the external handle assembly 1 and the linkage member can be locked by screwing down the jackscrew 9, and the locking form can be released by unscrewing the jackscrew 9, so that the external handle assembly 1 can slide along the linkage member. For the same reason, locking or releasing the relative position between the second rotary part 22 and the auxiliary is also achieved between the second rotary part 22 and the auxiliary 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 an inclination towards the door body direction, and a common screwdriver cannot operate the jackscrew 9 after the lock cylinder is installed on the door body, so that the aim of removing the outer handle by a thief through removing the jackscrew 9 on the outer handle assembly 1 is also avoided.
