Description

Technical Field

[0001] The utility model relates to the technical field of tree branch pruning devices, in particular to a pruning device which is convenient for pruning high places. Background Technique

[0002] Pruning devices that are convenient for pruning high places, such as high branch shears or high branch saws, have a variety of important uses. Pruning devices such as high branch shears can quickly and accurately prune branches and leaves at high places, especially in gardens, courtyards, public areas and other occasions, which can significantly improve the pruning efficiency.

[0003] In the existing technology, this device usually moves the cutting part to a specified height through a hydraulic device or an electric device, and also provides power by a diesel generator. The pruning part includes scissors or other cutting tools for actually pruning tree branches. These tools are usually installed on movable sliders or arms to facilitate precise positioning and adjustment during pruning. However, during actual use, when this device moves the pruning part to a specified position and after the pruning part finishes cutting, since the cut tree branch is separated from the tree, it is easy to fall to the ground due to gravity, which is likely to injure or scratch the staff working on the ground, making it impossible for the staff to dodge and protect in time, thus affecting the personal safety of the staff. Therefore, it is necessary to improve a pruning device that is convenient for pruning high places. Content of the Utility Model
