[0002] With the acceleration of urbanization, elevators are increasingly widely used in various buildings. As a kind of vertical transport equipment, elevators inevitably need regular maintenance and repair during long-term use. Elevator maintenance is often carried out in high-altitude dangerous environments such as elevator shafts, and maintenance personnel face the risk of falling, so it is crucial to ensure the safety of maintenance personnel during elevator maintenance.

[0003] Currently, there are some elevator maintenance anti-falling devices on the market. For example, some traditional anti-falling rods have a simple structure, usually a fixed-length rod body, which is fixed on the elevator door or shaft structure by simple hooks or clips. This fixing method lacks flexibility and is less adaptable to different specifications of elevator doors or different installation environments.

[0004] Specifically, since the door widths of different elevators differ, a fixed-length anti-falling rod may not fit closely to the elevator door structure for effective fixation, and may easily sway or displace during maintenance, thereby affecting the anti-falling effect. UTILITY MODEL CONTENTS
