The lock core of a safety padlock

The head of the lock core of the safety padlock has two pawls, the pawl and the locking tongue cooperate to complete the force conversion action, and the pawl replaces the locking tongue to move inwards, changing the rotation of the lock core into the movement of the locking tongue. In order to improve the anti - dialing effect of the lock, the key groove of the lock core is mostly processed into S or shaped.
