Description

Technical Field

[0001] The utility model relates to the technical field of tree pruning, in particular to a forest seedling pruning device. Background Art

[0002] In the daily maintenance and pruning of forestry seedlings, trimming tools are often used, but the existing trimming tools are usually ordinary hand-held flat scissors-shaped tools. When pruning seedlings, ordinary trimming tools require workers to hold the trimming tools and use manpower to prune branches, which requires huge manpower, is time-consuming and labor-intensive, and is not conducive to long-term and efficient branch pruning. In addition, when planting ornamental green plants such as Ligustrum lucidum, Elm vulgaris, Big Leaf Boxwood, Photinia fraseri, and Small Leaf Boxwood, gardeners prune and cultivate them to control the growth height so that their crowns become spherical and improve their ornamental value.

[0003] However, most of the existing pruning devices can only perform simple pruning of branches. When the crown of a special type of green plant needs to be pruned into a spherical shape, pruning can only be performed using pruning tools. Not only is the pruning efficiency low, but the crown is also difficult to prune into a round shape, and the crown is often pruned unevenly, affecting the aesthetics of the green plant after pruning.
