To facilitate an understanding of the present invention, the unlocking and locking processes of the present invention are described below:
when the character wheel 6 is not positioned at the position with correct codes, the lug 41 of the character wheel shaft 4 is not aligned with the through groove 51 of at least one bushing 5, so that the character wheel shaft 4 cannot move left and right relative to the bushing 5, at the moment, the inner end of the character wheel shaft 4 is clamped by one side edge of the acute angle pointed end 3111 and one side edge of the locking groove 24, and the inner end of the character wheel shaft 4 cannot be separated from the state clamped by one side edge of the acute angle pointed end 3111 and one side wall of the locking groove 24 by rotating the lock shell 2 through the clamping mechanism, so that the lock shell 2 is clamped by the character wheel shaft 4, and the lock shell 2 cannot rotate;
when the lock is required to be unlocked, each character wheel 6 is shifted to enable each character wheel 6 to be positioned at the position of a correct password, at the moment, each lug 41 on the character wheel shaft 4 is aligned with a through groove 51 of each bushing 5 to enable the character wheel shaft 4 to move left and right relative to each bushing 5, so that the lock shell 2 cannot be blocked by the character wheel shaft 4, at the moment, the lock shell 2 can rotate positively to complete unlocking, and when the lock shell 2 rotates positively, the character wheel shaft 4 is pushed to move through an acute angle tip 3111 to realize unlocking; moreover, due to the action of the acute angle tip 3111 of the lock tongue 31, the rotation of the lock shell 2 can enable each lug 41 of the character wheel shaft 4 to enter the through groove 51 of each bushing 5 and then withdraw from the through groove 51 of each bushing 5, after each lug 41 of the character wheel shaft 4 withdraws from the through groove 51 of each bushing 5, the bushings 5 and the character wheel 6 can rotate, and at the moment, the character wheel 6 can automatically rotate under the magnetic action between the character wheel magnet 61 and the character wheel shaft magnet 42, so that automatic code disorder is realized;
when the lock is needed to be locked, the lock shell 2 is reversely rotated, the inner end of the character wheel shaft 4 firstly presses the acute angle tip 3111 of the lock tongue 31 to enable the acute angle tip 3111 of the lock tongue 31 to enter the through hole 26, and the lock tongue reset spring T5 is compressed, so that the character wheel shaft 4 can pass through the acute angle tip 3111 of the lock tongue 31, after the character wheel shaft 4 passes through the acute angle tip 3111 of the lock tongue 31, the lock tongue reset spring T5 resets to enable the acute angle tip 3111 of the lock tongue 31 to penetrate out of the through hole 26, so that the inner end of the character wheel shaft 4 is clamped by one side edge of the acute angle tip 3111 and one side edge of the locking groove 24 to complete locking, at the moment, the lug 41 of the character wheel shaft 4 is not positioned in the through groove 51 of each bush 5 to enable the bush 5 and the character wheel 6 to rotate, and at the moment, under the magnetic effect between the character wheel magnet 61 and the character wheel shaft magnet 42, the character wheel 6 can be automatically rotated, and automatic code disorder is realized.
Further, in order to avoid that the user performs unlocking operation, the character wheel 6 automatically rotates due to the magnetic action between the character wheel magnet 61 and the character wheel shaft magnet 42, so that the user needs to press the character wheel 6 to prevent the character wheel 6 from rotating to enable each character wheel 6 to be positioned at a correct password position; the side wall of the character wheel 6 is also provided with a plurality of limit concave parts 63 which are uniformly arranged along the circumferential direction of the character wheel 6, and each limit concave part 63 corresponds to one code word of the character wheel 6; a lifting rod 7 which can move up and down along with the rotation of the lock shell 2 is further arranged in the shell 1, a plurality of character wheel positioning pieces 8 which are matched with the character wheels 6 in a one-to-one correspondence manner are matched on the lifting rod 7, and each character wheel positioning piece 8 is provided with a limit protrusion 811 which is movably clamped with the limit concave part 63; according to the invention, the lifting rod 7 and the character wheel positioning sheet 8 on the lifting rod 7 can be driven to move up and down through the rotation of the lock shell 2, so that whether the limit protrusion 811 on the character wheel positioning sheet 8 is clamped with the limit concave part 63 or not is controlled, when the limit protrusion 811 is clamped with the limit concave part 63, the damping of the rotation of the character wheel 6 can be improved, the magnetic action between the character wheel magnet 61 and the character wheel shaft magnet 42 can not enable the character wheel 6 to rotate, and at the moment, a user can quickly stir each character wheel 6 to a position with correct password; when the limit protrusion 811 is not engaged with the limit recess 63, the damping of the rotation of the character wheel 6 is small, and the magnetic action between the character wheel magnet 61 and the character wheel shaft magnet 42 can rotate the character wheel 6, thereby realizing messy codes.

Further, in order to avoid setting the password, the position of the character wheel 6 is set to a position where the character wheel shaft magnet 42 and the character wheel magnet 61 are homopolar and opposite, and the position is a blind spot position which can prevent the character wheel 6 from automatically scrambling the password; the character wheel 6 is further provided with an anti-blind-spot protrusion 64, the second end 82 of the character wheel positioning piece 8 is movably abutted against the anti-blind-spot protrusion 64, so that when the correct password position of the character wheel 6 is set to be the blind-spot position, in the process that the limiting rod 71 on one side of the lifting rod 7 moves downwards, the second end 82 of the character wheel positioning piece 8 is lifted upwards and the first end 81 of the character wheel positioning piece 8 moves downwards by the other side of the lifting rod 7, the limiting protrusion 811 is not clamped with the limiting concave portion 63, and then the second end 82 of the character wheel positioning piece 8 is lifted continuously, so that the second end 82 of the character wheel positioning piece 8 pushes the anti-blind-spot protrusion 64 to rotate for a certain angle, and the character wheel 6 continues to rotate, so that the character wheel 6 is separated from the blind-spot position, and messy codes are realized.
