With the vigorous development of hydropower, highways, bridges and culverts, real estate and other fields, there are more and more high-risk slope problems. It is difficult to support and manage tall slopes, among which, it is particularly difficult to clean up the lonely and dangerous rocks on the tall slopes. The reason is that: 1) the lonely and dangerous rocks of the tall and large slopes are difficult to clean up, and often the amount of work is large, and it is difficult to completely remove them in a short time and by using a general cleaning method. 2) The cleaning technology of lonely and dangerous rocks on tall slopes is not yet perfect, and it is difficult for machinery to go up, and most of them are climbed manually. 3) It is difficult to manually climb tall slopes, and it is even more difficult to remove heavy and dangerous rocks at the same time during climbing. Ordinary methods such as simply relying on manpower are often not thorough, leaving potential safety hazards. 4) Climbing cleanup personnel or manual cleanup personnel with the help of safety ropes may have accidents due to unstable footholds, and may also be threatened by the impact of lone and dangerous rocks that are not completely cleaned up. That is to say, the temporary security measures for construction personnel are very demanding, and it is difficult to provide effective security protection at present. 5) During the cleaning of tall and large slopes and the isolated and dangerous rocks falling due to incomplete cleaning, the impact energy is large, which is extremely harmful to other construction work surfaces with buildings, structures, traffic arteries or parallel operations at the foot of the slope. However, in the prior art, the protective net is fixed on the side slope by anchor rods, and the anchor rods are easy to fall off on slopes with loose soil, which affects the fixing of the protective net.

Therefore, in order to solve the above problems, there is a need for a fixing device for the slope protection net, which can effectively fix the slope protection net, and is stable, simple in structure, and easy to operate.
