Padlocks are the oldest and largest family in the world of locks. It can be said that other locks are derived from the category of padlocks. The lock body of the padlock is provided with a ring-shaped or “one” -shaped metal stem that can be fastened, that is, a “lock beam”, so that the padlock is directly connected to the lock body through the lock beam to form a closed lock.
