The lock can prevent the violent unlocking and reduces the mutual unlocking rate of the lock.

Description

technical field [0001] The invention belongs to mechanical locks, and relates to a safety lock head with a lock core that can rotate idly. Background technique [0002] In terms of locks, the tumbler lock has always been the most widely used product. Among the existing tumbler locks, there is a kind of lock that adopts a locking side column structure on the lock cylinder to cooperate with a pin with a V-shaped groove to control the opening and closing of the lock cylinder, which better solves the problem of traditional mechanical pin locks. Can not prevent technical unlocking and the weakness of picking and twisting the lock cylinder, its structure can refer to the ZL99115581.5 patent document. But this lock still has the problem that it is difficult to resist destructive forceful unlocking. If you use a strong enough lockpicking tool to forcibly pry the lock cylinder, you can twist the bolts that fix the lock head on the door. Moreover, this lock has only one row of marb...
