the traditional unmanned aerial vehicle is divided into two working environments when the unmanned aerial vehicle executes work, one of the working environments is that an electric wire is simply fixed with a traction rope through an adhesive tape or other tools, and then the upper end of the traction rope is suspended below the unmanned aerial vehicle for traction, so that the distance between the operation electric wire and the unmanned aerial vehicle is large, the swing amplitude of the electric wire is large due to the influence of the surrounding environment, the unmanned aerial vehicle cannot stably fly, and the accuracy error of the electric wire falling point is large; secondly, a traditional fixing clamp is installed below the unmanned aerial vehicle, the electric wire is fixed through the fixing clamp, the fixing clamp is operated to be completely fixed with the electric wire, when the unmanned aerial vehicle changes at a small angle, the fixing clamp generates a knob force on the electric wire, the unmanned aerial vehicle flies under a large influence through a reaction force of the electric wire, the traditional fixing mode cannot offset the knob force generated by the electric wire, when the knob force is greater than a friction force between the fixing clamp and the electric wire, relative movement can occur between the fixing clamp and the electric wire, so that the outer skin of the electric wire is abraded, and the quality of the electric wire is reduced; in addition, the transmission fixing clamp is basically exposed outside, and large resistance can be generated when the unmanned aerial vehicle flies at a high speed, so that the energy consumption of the unmanned aerial vehicle is increased.
