1. Pin classification

The pin is generally divided into two parts, one with a movable rod, and the other is a pin hole, also known as the "nose" of the pin.

2. Common applications of pins

Usually, the part with rod is fixed on the door, and the nose is fixed on the door frame, and the position should be corresponding. The structure is much simpler than that of a lock, but the effect is similar. The lock is just outside the door and the bolt is inside the door. When in use, the rod can be inserted into the nose.
