Description

Technical Field

[0001] The utility model relates to the technical field of tree pruning, in particular to a tree pruner for power distribution lines. Background Art

[0002] When laying out distribution lines in areas where there are no dense trees in the community, in order to avoid the influence of tree branches on the normal installation of the distribution lines, it is necessary to use pruning tools to trim the tree branches.

[0003] At present, when pruning tree branches during the installation of distribution lines, it is mainly achieved by using electric saws and manual pruning shears. Although both electric saws and manual pruning shears can be used to prune tree branches, when using electric saws for pruning, the electric saw is heavy, so the worker needs to hold the electric saw with both hands. After pruning, the workers need to put the electric saw down before they can manually clean the branches that have not fallen off after pruning. This makes the pruning and cleaning process of tree branches during the installation of distribution lines more cumbersome. Although manual pruning shears can be used to prune and clean tree branches at the same time, manual pruning will increase the labor intensity. Utility Model Content

[0020] (3) Beneficial effects

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] The present invention relates to a tree pruning tool which is mainly used for pruning branches of trees during the construction of power distribution lines. Although both the electric saw and the manual pruning tool can be used to prune tree branches, the electric saw is heavy and requires the operator to hold the electric saw with both hands. After pruning, the operator needs to put the electric saw down before he can manually clean the branches that have not fallen off. This makes the pruning and cleaning process of tree branches during the construction of power distribution lines more cumbersome. Although the manual pruning tool can be used to prune and clean tree branches at the same time, the manual pruning will cause greater labor intensity. The present invention adopts the coordinated design of the mounting frame, the handle and the pruning mechanism, so that the tree pruning tool can not only be held in a single-handed manner when in use, but also can prune tree branches in an electric pruning manner, which is convenient for the operator to efficiently prune and clean tree branches during the construction of power distribution lines, and at the same time greatly reduces the labor intensity during the pruning and cleaning process of tree branches, thereby facilitating the efficient construction of power distribution lines.
