[0002] Under the attack of extreme bad weather such as rainstorm and thunderstorm, the power grid power equipment suffers serious damage, in addition to part of the line being affected by lightning, the more prominent damage phenomenon is that the super-high trees on both sides of the protection area of the power transmission line are blown down or knocked down by lightning, the trees are discharged by contacting the conductor, and even the power supply line is tripped due to the direct smashing of the power line, causing a large-scale power failure accident, which has a serious impact on people's life and economic society. Moreover, once the high-voltage line is discharged, the fallen trees and their surroundings will have high-voltage electricity, and if someone accidentally enters, it may also cause casualties.

[0003] In order to solve the problem of circuit accident of power transmission line caused by trees, it is usually necessary to prune or cut down these trees, which is called tree barrier cleaning. For 220kV power transmission line, the distance between the tree and the line should be greater than 4.5 meters. Since cutting down the whole tree is easy to cause economic disputes, the tree branches are usually pruned, and the traditional tree barrier cleaning work is mainly completed by manual tools, hand saws or oil saws through tree climbing, high-altitude operation of arm truck or through extension rod, but manual cleaning of tree barrier has the problems of low working efficiency, high labor intensity and high risk of personnel falling from high place and electric shock.

[0004] The pruning machinery of power transmission line works mostly in the wild, and should have the ability to work for a long time, while the air platform type, along the line walking type and along the trunk climbing type pruning machinery mostly use electricity as the power source, and the endurance time is difficult to meet the working requirements. Many power transmission line erection positions are located in hilly and mountainous areas, and it is difficult to move large machinery to the specified position.

[0005] The material and size of the obstacle branches are various, and different end operation tools should be used for different materials and sizes, which can improve the pruning efficiency and prolong the service life of the operation tool, but the end operation tools of various pruning machinery are relatively single. Laser pruning belongs to high-temperature cutting, which has uncontrollable factors and is easy to cause fire. Considering the inconvenience of carrying the laser pruning equipment in the wild and the risk of fire. UTILITY MODEL CONTENTS
