[0002] In recent years, accidents involving falling objects from heights have become frequent at construction sites. Construction operations involve a significant amount of height work. Inadequate safety training and awareness among workers, coupled with inadequate safety protection at edges and openings, can lead to irreparable losses and casualties. Therefore, it is imperative to maintain safety at all times, implement various safety management systems, and ensure the deployment of adequate safety protection facilities.

[0003] For example, a Chinese patent with publication number CN202222474784 discloses an overhanging protective device, which includes a building, a scaffolding and a protective frame. The scaffolding is arranged on one side of the building, and the protective frame is inclined on one side of the scaffolding. The downward-inclined side of the protective frame is rotated at the bottom of the scaffolding through a rotating shaft, and a suspension rope is fixedly provided on the upward-inclined side of the protective frame. The end of the suspension rope away from the protective frame is fixedly connected to the top of the building, and a double-layer protective net is fixedly provided on the side of the protective frame.

[0004] The overhanging protective device described in the above patent can continuously set a fully enclosed overhanging protective safety net around the outside of the scaffolding to prevent objects from falling from the scaffolding and injuring people during scaffolding operations. However, it cannot effectively solve the problems of inconvenient installation and unstable structure in existing protective measures. Utility Model Content
