The locking and unlocking principle of the device is as follows: when the character wheel 5 moves to the correct code, the locking groove 44 of the character wheel core 4 and the locking block 32 on the core rod 3 are in the aligned state, that is, the core rod 3 can be moved, and at this time, the unlocking state is realized. When any password is in a disordered state (incorrect password), the locking groove 44 of the character wheel core 4 and the locking block 32 on the core rod 3 are in a staggered state, namely the core rod 3 cannot be moved, and the lock is in a locked state at the moment.

Before the device is installed, the position of the code searching block 45 is required to be just aligned with the position of the code searching groove 6 for installation, and the password displayed on the front side is the original password. When the password is changed, the lock is in the correct password, and then the code changing piece needs to be rotated to push the cushion block 40, so that the cushion block synchronously pushes the character wheel core to move, and the limiting block 42 is separated from the limiting groove 52, so that the character wheel 5 cannot drive the character wheel core 4 to rotate together. At this time, the character wheel 5 is rotated, and the function of changing the code is realized. After the code is changed, the code changing piece is dialed back again, so that the cushion block 40 moves back, at the moment, under the action of the end spring 36, the character wheel core 5 moves back, and the limiting block 42 is inserted into the limiting groove 52, so that the character wheel 5 can drive the character wheel core 4 to rotate together.

The code searching principle of the device is as follows: when the lock password is forgotten, the password can be retrieved by using the key. The key is inserted into the key hole 11 and then rotated, thereby rotating the lock cylinder 101. The tail of the lock core 101 is provided with an eccentric guide post 1011, and the guide post 1011 is inserted into the sliding groove 1021, so as to drive the lock tongue 102 to perform translational motion. The bolt 102 drives the moving plate 2 to move simultaneously. When the moving plate 2 moves, the inclined top block 21 acts on the inclined plate 62, so that the chip searching piece 6 (made of elastic material) moves upwards. The code searching sheet 6 is provided with code searching grooves 63 matching with the number of the character wheel cores, and the character wheel core 4 is provided with a code searching block 45 matching with the code searching grooves 63. At this moment, the character wheel is shifted, as long as the character wheel core is rotated to the position of the code searching block 45 and is just aligned with the position of the code searching groove 6, the code searching block 45 is clamped into the code searching groove 6 at this moment, so that the character wheel cannot be shifted any more, and a password is found. The same method is used to continue finding several other passwords.
