Problems solved by technology

[0003] Today's padlock structure is relatively simple. Although a lock can be equipped with a key by changing the length of the internal parts of the lock cylinder, etc., the mechanical principles are the same, which gives criminals an opportunity to stretch through small objects such as iron wires and blades. When entering the lock hole, the lock can be opened regardless of the inner structure of the lock cylinder. It cannot be recognized whether the user opened the lock by himself, and the safety performance is extremely low.
