Because the unlocking passages such as keys and character code runners are all exposed, it is convenient for the thief to detect the password; secondly, the combination lock has too high requirements for the installation environment. Therefore, the applicability is far less than that of the tumbler lock; however, the tumbler lock has a relatively simple structure, but it is very easy to be opened violently or technically, the mutual opening rate is too high, and the anti-theft performance is poor. 3.
