Abstract

An isolated anti-theft lock head differs from a common lock head in that a key inserted into an insertion hole does not directly contact with a tumbler in a lock and can contact with the tumbler only after rotating by a certain angle. The tumbler and the insertion hole for the key are isolated by a cylinder body in a lock body and a lock core, so that the tumbler can not be unlocked by an external object; the lock core is sleeved in the lock body, so that the external object is difficult to rotate the lock core; however, when the key to the lock is used, a connection narrow handle in an unlocking area can conveniently reach the tumbler area through a slit in the lock, so that the lock head can be unlocked easily and smoothly; and the lock body can be made very firm without affecting the performance. The isolated anti-theft lock head is a lock head extremely firm and very difficult to unlock for theft.
