According to the design principle, ancient Chinese locks have two types including the splitting spring lock and the combination lock. The splitting spring lock is most popular one in ancient Chinese. It uses the simple elasticity and the clever dimensions to tie in with the design of key. The locking and opening functions are generated. Combination locks usually have three to seven wheels. They are of the horizontal round-pillar shape with several tunable wheels of the same size set in array on the central axis of the pillar body. Each wheel has the same amount of carved letters. Once the letters from all wheels are turned to the pre-set order and form a specific word, the lock is ready for opening. This object is a combination lock with five wheels.
