[0002] With the development of science and technology, people's lives cannot be separated from electricity. Electricity poles can be seen everywhere on the roadside. Electricity is transmitted to every household through the poles supporting the wires. The most common poles are made of concrete and steel bars. The shape of the poles is generally equal-diameter poles with a diameter of 300~550mm and a height of about 8~15m. In order to ensure people's normal electricity use, it is necessary to inspect and maintain the crossarms, insulators and wires on the poles.

[0003] When inspecting components on utility poles, workers usually wear foot buckles and climb to the top of the utility pole to carry out inspection. When inspecting components on utility poles, because there is no fixed place on the utility pole, workers usually put safety belts around the utility pole and then lean back slightly to increase the friction between the utility pole and the safety belts. However, this will cause greater wear on the safety belts, which are prone to breakage after long-term wear, posing a greater safety hazard to the workers' inspection work. Utility Model Content
