Description

Technical Field

[0001] The present application relates to the technical field of municipal engineering, and in particular to a shrub pruning device. Background Art

[0002] During the process of urban road construction, low ornamental shrubs are usually planted on both sides of the road. Ornamental shrubs can not only improve the beauty of the city appearance, but also purify the dust and reduce noise in the environment.

[0003] Ornamental shrubs need to be modified frequently to prevent their top branches from moving around and to keep their tops roughly flat, thereby improving their aesthetics. However, the existing pruning method generally requires workers to use handheld pruning machines for pruning. Workers are prone to fatigue from holding pruning machines for a long time, and there are deviations in the pruning heights for different shrubs. In the prior art, the pruning height can only be maintained by the workers' arms. If the arms are kept at a fixed height for a long time, the arms are prone to soreness, and it is difficult to maintain a constant height, resulting in the phenomenon of gaps being easily produced during pruning. Therefore, a shrub pruning device is needed. Utility Model Content
