as shown in fig. 13, in the locked state, due to a wrong combination, the limit block 344 on the lock block 340 cannot be pressed into the limit groove 332 of the engaging wheel 330, so that the lock block 340 is in a middle position, i.e., a locking stop, the end of the lock block 340 blocks the traveling path of the unlocking linkage 310, and the unlocking linkage 310 also prevents the push button 400 from unlocking.

As shown in fig. 14, when the combination is correct, the limiting grooves 332 of all the engaging wheels 330 face the limiting blocks 344 of the locking blocks 340, the locking blocks 340 are swung to a lower position, i.e., a first unlocking rail, by the action of the fifth springs 343, the ends of the locking blocks 340 vacate a space for the unlocking linkage 310 to travel, and at this time, when the push button 400 is pressed, the locking grooves 410 move downward along with the interference linkage of the push button 400 and the unlocking linkage 310 to disengage from the locking hooks 500 for unlocking.

As shown in fig. 16, when the password is correct, the password adjusting switch 360 is toggled to extrude the slider 380 towards the direction of the matching wheel 330, the matching wheel 330 temporarily leaves the password wheel 320, the password wheel 320 can adjust the password, after the password wheel 320 adjusts the password, the password adjusting switch 360 is toggled in the reverse direction, the slider 380 resets under the matching of the sixth spring 371, and the password adjustment is completed.

As shown in fig. 15, when the key is needed to unlock the lock, the rotating block 610 rotates along with the lock cylinder assembly 600, the rotating block 610 swings the locking block 340 to the upper position, that is, the position of the second unlocking position, the locking block 340 avoids the unlocking linkage 310 again, and a space for the unlocking linkage 310 to travel is provided, at this time, when the push button 400 is pressed, the locking slot 410 moves downward along with the interference linkage of the push button 400 and the unlocking linkage 310 to disengage from the lock hook 500, so as to unlock the lock.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to explain the principles of the invention, and that various modifications and alterations can be made by those skilled in the art without departing from the spirit and scope of the invention.
