Problems solved by technology
[0002] At present, there are mainly two types of locks, combination locks and mechanical locks. Both combination locks and mechanical locks have their own scope of application and advantages and disadvantages. The most commonly used mechanical locks are tumbler locks, which have the advantages of simple structure and low cost. However, it is also easy to be opened by people using unlocking techniques such as bumper key unlocking and tin foil unlocking, and the problem of poor anti-theft performance, while the Super B lock with good anti-theft performance has the disadvantages of complex structure and high manufacturing cost.
