Besides, said invention also provides the working principle of said safety lock and its concrete operation method.

Description

technical field [0001] The invention belongs to mechanical locks, and relates to a safety lock head capable of preventing opening and prying. 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 uses a locking side post mechanism 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 unlocking tool to forcibly twist the lock cylinder, you can twist the bolts that fix the lock head on the door. Moreover, this lock has only one row of marbl...
