When the resident is in the house, in order to further improve the security, the lock is generally provided with a reverse locking mechanism. For example, a Chinese utility model patent with the publication number CN219471758U discloses a rotary lock position type handle structure, which comprises an indoor door handle and an outdoor door handle. A square shaft is arranged between the indoor door handle and the outdoor door handle. A lock cylinder is arranged on the outdoor door handle. A rotary knob is arranged on the indoor door handle. Rotary lock position structures are arranged in the indoor door handle and the outdoor door handle. The two ends of the square shaft are respectively connected and positioned with the two rotary lock position structures. The resident can effectively and quickly realize the locking or unlocking operation by rotating the rotary lock position structure in the house, so that the door leaf cannot be opened outside. However, with different application scenarios, some rooms need to be opened to different users at different time periods. For example, all users can open the lock during the working period, only the user with the correct unlocking instruction can open the lock during the non-working period, and only a few users with the correct unlocking instruction can open the lock during the specific period. It can be seen that the existing lock reverse locking structure cannot meet the use requirements of people because of the single function. SUMMARY
