Abstract

The invention relates to a lock which comprises a lock body and a lock lug connected with the lock body. A lock body mounting hole is formed in the lock body. A first elastic piece is arranged at the bottom of the lock body mounting hole. The bottom of one end of the lock lug is located in the lock body mounting hole and connected with the first elastic piece. A lock lug mounting hole is formed in the position, on the outer side face of the lock lug, of the inside of the lock body mounting hole. A second elastic piece is mounted in the lock lug mounting hole and connected with a pin tumbler. A pin tumbler hole matched with the pin tumbler is formed in the inner wall of the lock body mounting hole. A through hole extending to the pin tumbler hole is formed in the periphery of the lock body. The lock is reasonable in structural design, low in cost, and convenient to use; the unlocking difficulty is increased when locking is achieved through the lock; and since blind holes are formed in the lock body, the lock has a multiple anti-theft function, the anti-theft coefficient is very high, and the lock deserves to be widely applied and popularized.
