The password roller 620 drives the sleeve 640 to rotate by locking the locking tooth 642 into the toothed groove 621.

[0032] The principle of the locking assembly 500 in this embodiment is as follows: When the password is correct, the limiting block 612 on the spindle 610 aligns with the limiting groove 641 of the sleeve 640. At this time, pressing the button 530 causes the push block 551 to push the spindle 610 through the first inclined part 552 and the second inclined part 532. The limiting block 612 inserts into the limiting groove 641, allowing the button 530 to move inward. The push rod 531 of the button 530 pushes the locking member 520 to rotate, causing the locking block 521 to disengage from the locking groove 403, thereby allowing... Open the flip cover 400; when the password is incorrect, the limiting block 612 on the spindle 610 and the limiting groove 641 of the sleeve 640 are not aligned. At this time, press the button 530. The button 530 pushes the spindle 610 through the push block 551. The limiting block 612 of the spindle 610 and the end face of the sleeve 640 abut against each other, and the spindle 610 cannot move. The support block 204 at the rear end of the push block 551 restricts the push block 551 from moving backward, so that neither the push block 551 nor the button 530 can move, thus preventing the flip cover 400 from opening. To change the password, first enter the correct password, then insert a thin rod through the fifth through hole 207 on the outer cover 200 to push the outermost sleeve 640, causing the sleeve 640 to move towards the push block 551. The locking teeth 642 of the sleeve 640 disengage from the grooves 621 of the password roller 620. At this time, rotate the password roller 620 to the new password, pull out the thin rod, and the sleeve 640 returns to its original position, thus setting the new password.

[0033] The outer cover 200 has a protrusion 205 on its inner side, and the bottom of the inner cover 100 has an annular groove 101 that matches the protrusion 205. The inner cover 100 and the outer cover 200 are rotated together by the protrusion 205 being engaged in the annular groove 101. The inner cover 100 has guide grooves 102 to facilitate the engagement of the protrusion 205 into the annular groove 101. The number and position of the guide grooves 102 correspond to the protrusion 205. During installation, the protrusion 205 and the guide groove 102 are aligned before the outer cover 200 is pressed onto the inner cover 100, which facilitates the engagement of the protrusion 205 into the annular groove 101.
