The lock comprises a lock shell, a lock cylinder, a moving post and a braking post, wherein a lock shell braking post hole is arranged in the lock shell; and a lock shell moving post hole is arranged in the side wall of the lock shell. The lock cylinder is sleeved in the lock shell, and is provided with a lock cylinder braking post hole corresponding to the lock shell braking post hole. A lock cylinder moving post hole is arranged in the lock cylinder and is a through hole for the lock cylinder to pass through; and the both ends of the lock cylinder moving post hole respectively correspond to the lock shell moving post hole which is arranged in the side wall of the lock shell. The lock cylinder braking post hole and the lock cylinder moving post hole are communicated with each other. The lock cylinder is axially provided with a key hole. The key hole is communicated with the lock cylinder moving post hole. The moving post is arranged in the lock cylinder moving post hole. The moving post is provided with a clamping groove and a protruding part extending into the key hole. The braking post is arranged in the lock cylinder braking post hole; and one end of the braking post is provided with an arc-shaped face, and the other end of the braking post is provided with a bump fit with the clamping groove in shape. The moving post and the braking post of the lock are in a braking type design; and the braking post is hidden in the lock cylinder and is difficult to contact from the outside and damage by an external force.

The tumbler lock is widely used because of its simple structure and practicality. The structure of the pin lock is roughly the same, that is, a group of cylindrical pins are installed in the pin hole of the lock cylinder, and the key has a corresponding depth of teeth. The method of unlocking is roughly the same, that is, move the corresponding pins up and down according to the different heights of the key teeth, so that the height of each lock pin pin is at the interface between the lock shell and the lock core, and then rotate the key to drive the lock. Core, to achieve the purpose of unlocking. This type of lock is located in the shifting tooth channel. Without touching the pin, foreign matter can easily enter the inner end of the keyhole, and various unlocking tools can be inserted through the shifting tooth channel for technical unlocking. ...
