Description

Combined hook knife

technical field

The utility model relates to an auxiliary tool for electric power operation, in particular to a combined hook knife.

Background technique

Pruning super tall trees and bamboos is a necessary work for maintaining high and low voltage lines. Electric power workers must conduct regular inspections and inspections of the cable lines under their jurisdiction every month, and assist in cleaning up tree and bamboo obstacles on each line every month. It is usually used to climb to a higher position by means of stairs or directly climbing, and then use tools such as chainsaws, chainsaws or sickles to cut down tree and bamboo obstacles. This method is time-consuming and laborious, and there is a safety risk of falling from a height when climbing or using a ladder to trim. In addition, it is also possible to tie agricultural knives on the bamboo poles, and the operators can trim the trees and bamboos by standing on the ground, but the knives are easy to break away from the bamboo poles and fall during use, which is dangerous, low in work efficiency, and inconvenient to carry. Tree bamboo of different heights is trimmed, can not satisfy the demand of a large amount of tree bamboo trimming work.

Therefore, there is a need for a combined hook knife, which enables operators to trim trees and bamboos without climbing or using height-climbing tools, effectively controls the safety risks of falling from high altitudes and electric shocks caused by trimming trees and bamboos, has high safety in use, and is portable It is convenient to trim trees and bamboos of different heights, and the structure of the cutter body can improve work efficiency and meet the needs of a large number of trees and bamboos.
