Now, the lockbox lock on the market is composed of three wheels with three numbers designed by three digital wheels The three plastic gears are put on a plastic post at the same time and the plastic gear can be opened by turning the lock to the right place. With these three gear with the gear (a 2CM about the plastic strip, there are three gear holes) under pressure, the left side of the gear spring play a role, the gear bar to the right, pushed open the right of a column (the column Jammed the two wheels that opened the lock so that the lock could not be opened), leaving the key lock open. Each wheel consists of 0-9 these numbers, so you can combine into 1000 numbers, you want to open, there are only two ways, the first to know the password, the second one one. The latter is a stupid way, there may be more than a dozen can be opened, it may try to break the password lock, is not a good idea. Trolley lock set when the box must be in the open state Plastic hook the digital wheel and plastic gear separate rotation of the plastic wheel under the number wheel does not move, release the lock, the number keys and plastic gear engagement, turn the number of gear Also move.

Exclusion method, not good. 4, get three numbers, the number of bit by bit processing: less than 5 plus 5, greater than 5 minus 5, that is, get the password. For example: observation groove to get 911, the password is 466. 9-5 = 4,1 + 5 = 6,1 + 5 = 6.
