In a complete door lock, the lock cylinder controls the operation of the mortise lock, and the mortise lock is responsible for opening and locking the door, which plays an important role in security. The square tongue and the oblique tongue play the most critical role.

The latch - the protruding part of the mortise lock, the rearward compensation of the reset spring, and the door is buckled when the door is closed, so that the door stays in the closed state.

The mortise lock is a special type of lock used in the commercial safety industry and requires heavy duty and high frequency lock applications. The selection of the mortise lock should be based on the choice of the type of the root door and the actual situation. One of the advantages of the European mortise lock is that even the mortise lock is produced, the lock cylinder and the drive member (door handle) are produced by different manufacturers, but the specifications are uniform and match each other to produce different functions, which is also the European mortise lock. The door can only play its biggest role if it is matched with a reasonable door hardware.
