After the drill bit is drilled into the lock hole, the lock will rotate synchronously with the drill bit when rotating, which can play the role of the lock without being damaged. The lock requires three-direction locking structure, three hinges for single door opening, six hinges for double door opening, and a door lock for door leaf and door frame. Even if the hinge is broken, the door cannot be opened.
