The difference between a square tongue and a latch tongue is that it does not include a spring member and therefore cannot automatically pop up or retract due to external force. The square tongue is controlled by the action of opening the door to lock the door, and the fixing property is strong. Because of this feature, we must make the square tongue function through the operation. This is why most of the outside door locks are used with diagonal tongue and square tongue.
