Line clearing work is an important daily work of power supply enterprises, including two parts: inspection and clearing. However, in actual operation, there is social resistance to sawing off the trunk and secondary branches of offline trees. In the process of negotiating with the government, villages, teams, and farmers, there will be unaffordable compensation or disputes, which will lead to the failure to remove the hidden dangers of the tree barriers in time, causing safety hazards, and there are passive factors. Therefore, strengthening inspections, especially shortening the inspection cycle during peak tree and bamboo production in spring and summer, pruning immediately once new trees and bamboo new branches are found, is a more active line maintenance method for the power supply department. Common pruning knives are usually used for pruning, but common pruning knives have the following problems in use:

1. Ordinary pruning knives need to be trimmed from a height, which is prone to the risk of falling from a high place, resulting in personal injury.

2. During the pruning process, because the trees and bamboo branches are too close to the live wires, the trees and bamboo branches shake during the operation process, and ordinary pruning knives are prone to electric shock and personal injury.

3. Ordinary pruning knives cannot measure the distance between the branch and the wire, and the maintenance work is complicated in the early stage.
