Handlock / workspace


Where is the lock? You should find the lock before you lock the door , but the person who opened the door couldn`t tell you every time where the lock he put it on. Is there one way to make locking to become a simple thing? Yes. A simple combination of a lock and door handle make people convenient to lock the door . At the same time, the person who open the door shouldn`t consider the problem where he should put the lock?
