With the above technical means, when the user forgets the correct password of the password lock 30 and cannot unlock, the following procedure can be performed to retrieve the correct password:

1. The anti-riot knob 80 can achieve an anti-riot effect to avoid external damage. When the anti-riot collar 88 is subjected to excessive rotational force, the positioning bead 885 is disengaged from the brake groove 863 and retracted into the receiving hole 883, so that the anti-riot collar 88 is opposite to the inner cylinder. The body 86 is free to rotate, whereby when the violent person turns the tamper knob 80 in a violent manner to break the code lock, only the tampering collar 88 can be idling, and the inner cylinder 86 cannot be further forced to cause any damage.

2. Inserting and pressing the key lock 70 through an administrator key (not shown), thereby pressing the lock bead 72 inside the outer casing 76, and causing the lock lock 70 to enter the unlocked state due to the locked state, such as The sixth picture is shown. At this time, the radial sliding groove 731 of the radial projection 73 is aligned with the thin rod portion 721 of the corresponding locking ball 72 to be slidable relative to the inside and outside of the guide hole 763 of the outer casing 76.

3. Referring further to the seventh diagram, the controller lock is then rotated to rotate the key lock 70 and the drive transmission member 44 is slid downward, and the flange at the outer end of the alignment lever 42 is further aligned with the corresponding recess on the transmission member 44. The groove 442 is at the same time, and the inner ends of the alignment rods 42 respectively abut against the outer walls of the corresponding locking cylinders.

4. Referring further to the eighth figure, the password registration groove 323 of the lock sleeve 32 can be aligned with the registration lever 42 by rotating the code dial 33 so that the alignment lever 42 is inserted into the password registration slot 323. After the alignment, the alignment lever 42 can further penetrate the password registration slot 323. At this time, the combination of the numbers seen by the user in the window 22 is the correct combination of passwords, and the alignment lever 42 cannot enter the password registration slot 323. After moving, the user can know that the password has been found.

5. When the previous step is performed, the password dial 33 will be locked. When the function of the rotation of the password dial 33 is to be repeated, the controller key is reversed in the opposite direction, so that the transmission member 44 is slid back to the upper position and the alignment is made. The flanges of the rods 42 are respectively slid out of the recessed grooves 442 along the inclined surfaces 445 of the corresponding recessed grooves 442. At this time, the alignment rod 42 is separated from the password alignment groove 323 of the corresponding locking sleeve 32, the code dial 33 and the lock buckle. The sleeve 32 is again rotated. In this way, the user only needs to insert the administrator key and turn the password dial 33 to obtain the correct password, without any means of relying on eyesight. This allows the user to retrieve the password quickly and accurately.
