[0002] At present, in the field of construction, safety nets are a kind of protective equipment to prevent falling injuries. They are widely used to prevent people and objects from falling, or to avoid or reduce injuries caused by falling and being hit by objects. They are mostly used in various high-altitude operations. The hidden dangers of falling in high-altitude operations often occur in shelves, roofs, windows, suspensions, deep pits, deep grooves, etc. The role of the safety net is to block the falling people and objects, avoid or reduce injuries caused by falling and being hit by objects. The strength of the net must withstand the weight and impact distance of the human body and the tools and other items when they fall, and the longitudinal tension and impact strength. A safety net must be hung below the high-altitude operation site.

The rubber layer is arranged in the device, and the elasticity and softness of the rubber layer can prevent people from being easily injured when falling on it, so it is highly practical and has wide practicality.
[0004] However, the above scheme still has some shortcomings. For example, the above scheme reduces the vibration and force caused by a person falling by setting a rubber layer and utilizing its elasticity and softness, but the impact weight that can be borne is relatively limited and the safety is relatively low.
