The invention discloses a clutch type clock and keys. The lock comprises a clutch type lock cylinder, a transmission mechanism and a lock sleeve, the keys are matched with the lock cylinder, the transmission mechanism comprises an inner sleeve, a lifting pin, a limiting pin and a clutch pin, the lock cylinder rotates to form a clutch through groove, the lower portion of the clutch pin enters the clutch through groove after the clutch pin is pressed by the lifting pin, the upper portion of the clutch pin is located in a strip-shaped hole of the clutch pin of the inner sleeve, and unlocking is achieved through linkage of the lock cylinder and the inner sleeve; when the lock cylinder rotates reversely to be locked, the limiting pin limits the inner sleeve to rotate continuously, the lock cylinder continuously rotates reversely to make the lower portion of the clutch pin pressed into the strip-shaped hole of the clutch pin, the upper portion of the clutch pin enters a groove of the lock sleeve, and linkage of the lock cylinder and the inner sleeve is removed. According to the clutch type clock and the keys, the lock cylinder is further improved, and the lock cylinder comprises the multiple coding plates. The clutch type clock and the keys have the advantages that the structure is simple, the transmission is stable when the lock is unlocked or locked, the coding information content of the lock cylinder is large, and the capacity of controlling technical opening is strong.
