Abstract:
An on-off type lock and a key. The lock comprises an on-off type lock cylinder, a transmission mechanism and a lock sleeve (9); the key (1) is matched with the lock cylinder; the transmission mechanism comprises an inner sleeve (8), a lifting pin (71), a limiting pin (72) and an on-off pin (6); the lock cylinder rotates to form an on-off through groove (200), the lower part of the on-off pin (6) enters the on-off through groove (200) after the on-off pin (6) is extruded by the lifting pin (71), and the upper part of the on-off pin (6) is located in an on-off pin strip-shaped hole (81) of the inner sleeve (8), so that linkage unlocking between the lock cylinder and the inner sleeve (8) is realized; and after the lock cylinder rotates reversely and is locked, the limiting pin (72) limits the inner sleeve (8) from continuously rotating, the lock cylinder continues rotating reversely to extrude the lower part of the on-off pin (6) into the on-off pin strip-shaped hole (81), and the upper part of the on-off pin (6) enters a groove of the lock sleeve (9), so that linkage between the lock cylinder and the inner sleeve (8) is removed.
