[0037] Please refer to Figures 1 to 3 The lock cylinder jacket 10 has a containing through hole 11; the containing through hole 11 penetrates through opposite ends of the lock cylinder jacket 10.

[0038] Please refer to Figures 1 to 3 The idle cylinder 20 is rotationally connected to one end of the lock cylinder jacket 10, and the rotation direction of the idle cylinder 20 is along the circumference of the lock cylinder jacket 10; the idle cylinder 20 has a hollow structure and is sleeved on one end of the lock cylinder jacket 10.

[0039] The mechanical clutch assembly 30 comprises a mechanical lock cylinder 32 and a clutch piece 31, both of which are located in the containing through hole 11; a key can be inserted into the mechanical lock cylinder 32, so that the mechanical lock cylinder 32 is driven to rotate by the key by a certain angle, such as 90 degrees.

[0040] The electronic clutch assembly 40 comprises a clutch cylinder 41 which is sleeved on the lock cylinder jacket 10 and is arranged to slide along the axial direction of the lock cylinder jacket 10, and a driver 42 which is used to drive the clutch cylinder 41 to move;

The mechanical lock cylinder 32 can drive the clutch piece 31 to abut against the idle cylinder 20 under the action of an external force, for example, the mechanical lock cylinder 32 is driven to rotate forward by 90 degrees by a key, the mechanical lock cylinder 32 converts the rotation of itself into linear movement of the clutch piece 31, so that the clutch piece 31 moves towards the idle cylinder 20 and abuts against the idle cylinder 20, and at the same time, the rotation of the idle cylinder 20 relative to the lock cylinder jacket 10 is limited, the idle cylinder 20 is in the synchronous state and can rotate synchronously with the lock cylinder jacket 10. At this time, the lock cylinder jacket 10 can be driven to rotate by rotating the door handle by hand, the lock cylinder jacket 10 drives the idle cylinder 20 to rotate synchronously and to be unlocked. When the mechanical lock cylinder 32 is reversely rotated, the clutch piece 31 is separated from the idle cylinder 20, and the limitation on the rotation of the idle cylinder 20 is removed, the idle cylinder 20 is in the idle state, at this time, the lock cylinder jacket 10 is driven to rotate by the door handle, but the lock cylinder jacket 10 cannot drive the idle cylinder 20 to be unlocked, and the door lock is in the locked state.
