Because the structure of the door lock body is generally too small, the lock tongue is usually a short column made of metal. When the door is locked, if it is hit by an external force, the lock tongue will often slip out of the strike plate. or get crashed. In addition, the structure of the door lock is small, and the installation is too simple. After being hit, the phenomenon that the entire door lock will be knocked down will occur. Contents of the invention [0003] In view of the defects in the above...
