Abstract: A lock includes a lock housing, a cylinder assembly rotatably arranged in the lock housing and a locking keyless assembly connected to the cylinder assembly in a transmission way. The cylinder assembly includes a cylinder core and a tailpiece unit, a first clutch mechanism is provided between the cylinder core and the tailpiece unit, and a second clutch mechanism is provided between the locking keyless assembly and the tailpiece unit. When the second clutch mechanism is engaged, the locking keyless assembly is movable relative to the lock housing in a first direction under a driving of an external force for locking, and the cylinder core and the tailpiece unit rotate along with the locking keyless assembly. When the external force on the locking keyless assembly is withdrawn, the locking keyless assembly moves in an opposite second direction opposite, so that the second clutch mechanism switches to a disengaged state.

Abstract: A locking device comprises a latch, a spindle and a rotary assembly. The latch is fixed to an object to be locked for engaging with a bore of a strike; the latch has a bolt which locks the object. One end of the spindle is detachably connected to the latch to drive the bolt to move towards or away from the bore. The rotary assembly is disposed at the other end of the spindle, which comprises a cylinder body and a rotary body, the cylinder body is rotated by the rotary body as it rotates, wherein one end of the rotary assembly is provided with a spindle driving means engaged with the other end of the spindle to drive the spindle to rotate. The rotary assembly drives the spindle to rotate via the spindle driving means, and the spindle drives the bolt to move approaching the bore to realize locking.

Abstract: A manual/automatic dual-purpose clutching structure includes a driving gear assembly, a reversing clutching assembly and a driven gear assembly. The driving gear assembly includes a first gear, a second gear and a driving module, the first gear being coaxially and fixedly connected to the second gear. The reversing clutching assembly includes a reversing gear and a reset spring, the reversing gear is located on one side of and meshes with the second gear. The driven gear assembly includes an output gear which is located on the other side of and does not make contact with the second gear. The reversing gear rotates around a central axis of the second gear under a driving of the driving module to mesh with the output gear. After power of the driving module disappears, the reversing gear is prompted to be disengaged from the output gear under an action of the reset spring.
