Background

For example, the combination locks of the prior art having application numbers CN201620192162.4, CN200320121949.4, and CN200910260645.8 include a lock case and a combination lock core, the combination lock core is disposed inside the lock case and has a lock bolt, a plurality of lock catch sleeves, and a plurality of combination turntables, the lock catch sleeves are sleeved outside the lock bolt, and the combination turntables are respectively sleeved outside the lock catch sleeves and can drive the corresponding lock catch sleeves to rotate together.

When the coded lock is in a locked state, the lock bolt can abut against the lower part of the lock catch sleeve which is not rotated to a correct angle, so that the lock bolt cannot be pulled out upwards to achieve the aim of locking; after the user dials the code dial and drives the lock sleeve to rotate to the correct unlocking position, the code lock is in the unlocking state, and in the unlocking state, the notches of all the lock sleeves are aligned with the corresponding lugs on the lock bolt and the lock bolt can be drawn out upwards through the notches of the lock sleeves by the user, so that the unlocking purpose is achieved.

However, the above-mentioned combination lock does not provide a mechanism for the user to find the correct combination, in other words, when the user forgets the previously set combination, the user must test the combination one by one or directly destroy the combination lock.

In order to overcome the above-mentioned drawbacks of the conventional combination locks, the inventor has invented a combination lock with verification holes, wherein the lock case is provided with a plurality of test holes corresponding to the locking sleeves, and the test holes are used for the user to verify and test the status of the locking sleeves and further to retrieve the correct combination.
