Description

Technical Field

[0001] The invention relates to the field of hedge trimming, in particular to a road hedge trimming device. Background Art

[0002] Any regular planting pattern in which shrubs or small trees are planted closely together in single or double rows is called a hedge. It is usually planted along the edge of a road or street to form a green belt, which not only beautifies the environment but also helps improve traffic safety and the environment.

[0003] As shrubs or small trees continue to grow, their branches will stretch out. On the one hand, the stretched branches will affect the appearance. On the other hand, since these shrubs or small trees grow on the edge of the road, the stretched branches will also block the road and cause harm to pedestrians on the road. Therefore, when the shrubs or small trees grow to a certain extent, they need to be pruned, and pruning is divided into rough pruning and fine pruning. Rough pruning is to use the existing hedge trimmer to directly cut off all the stretched branches, while many still need fine pruning for good looks, and hedge shears are used for targeted pruning.

[0004] However, conventional hedge shears have the following disadvantages: branches of shrubs and hedge plants always grow in different directions, and some branches may block branches that need to be pruned. The hedge shears must rotate the blade to aim at the desired branch to avoid cutting other branches. Therefore, the user often needs to change the position of the handle so that the blade can perform correct shearing. Therefore, the hedge shears are very inconvenient to use. It is particularly difficult to change the position of the blade when the user must stand on a ladder or is restricted in movement. When a lot of effort is required to change the position, the user is easily tired, which affects efficiency or productivity. Summary of the invention
