Anti-theft buckle function:
The anti-theft buckle is installed on the back of the door, not far from the door. One end of the door buckle is fixed on the door frame, and the other end is movable and can be locked in the base groove on the back of the door. After the anti-theft button is buckled, the door can only be opened to about 5~8 cm at most, so people can't get through and their hands can't reach the button behind the door.
Unable to turn on the anti-theft button to ensure that the host will not be suddenly attacked by the other party when he opens the door to confirm the identity of the visitor. Because the anti-theft buckle will be forcibly cut by tools such as metal cutting pliers, the anti-theft buckle is rarely used as a door lock alone, but only as an anti-theft auxiliary tool. But because the door itself has anti-theft and safety functions, the anti-theft buckle is very practical.
Breaking and entering is usually violent knocking on the door or technical unlocking. Hit the door violently to test the endurance of the door. After technical unlocking, it is necessary to use tools such as hydraulic tongs to forcibly destroy the anti-theft buckle before entering. Indoor owners can call for help, call the police and save themselves during this time, so the anti-theft buckle has certain anti-theft ability.
