Description

Forestry branch trimming means Technical Field The utility model relates to the technical field of forestry branch trimming, in particular to a forestry branch trimming device. Background Under the natural growth condition, the branches of the tree in the forestry are uneven in growth, so that too dense branches, overlapping branches, crossed branches, thin and weak branches, pest branches and the like are easy to form, the branches are not attractive, the growth and development conditions of the forestry are affected, and therefore forestry nursing staff are required to trim the branches of the forestry, the tree in the forestry is good in growth and development, the forestry production value is improved, and meanwhile the forestry is tidier and attractive. Through retrieval, the forestry branch trimming device with the publication number of CN218184158U comprises a device body, a telescopic mechanism and a disassembling mechanism, wherein the device body comprises a trimming rod, the surface of the trimming rod is movably connected with an electric saw, the telescopic mechanism comprises a connecting rod, the connecting rod is movably connected with the inner surface of the trimming rod, the disassembling mechanism comprises a second fixing block, the second fixing block is fixedly connected with the outer surface of the trimming rod, and the surface of the second fixing block is movably connected with a screw rod. According to the utility model, the connecting rod and the auxiliary rod are placed in the inner part of the pruning rod to be flexibly connected and fixed, so that the electric saw can prune branches at a longer distance with the help of the pruning rod, and the limitation that the pruning device cannot prune branches at an excessive distance is avoided. Through mutual limitation and fixation among the screw rod, the movable ring, the first movable column and the second movable column, the electric saw is convenient to detach and install on the pruning rod, and the electric saw can be replaced and reused in time after being damaged When the device in this published patent is pruning the branch in high altitude, need the staff to hold the pruning pole always, prune the branch with the electric saw, because the branch that needs to prune is more numerous, the staff holds the pruning pole for a long time, makes the arm take place very easily and ache, can cause handheld unstability, prunes the pole and follow the problem of slipping in the hand.
