Description
Technical Field
[0001] The utility model belongs to the field of seedling pruning industry, and specifically relates to a portable seedling pruning device. Background Art
[0002] Seedlings refer to young trees or shrubs planted in nurseries. After a certain period of growth, they are transplanted to other places for planting. Seedlings can be ornamental plants, such as flowers and landscape trees, or economic crops, such as fruits, vegetables and trees. Seedlings need to be pruned during their growth. Pruning seedlings can promote growth, improve appearance, increase health and enhance the yield of fruits and flowers. Seedlings are usually pruned using pruning devices. During pruning, when it is necessary to prune the branches of seedlings at high places, it is inconvenient to clamp and fix the thicker branches, resulting in instability of the pruning device during the pruning process, thereby damaging the growth of the seedlings. In addition, branches will directly hit the hands during the pruning process, and it is inconvenient to automatically adjust the height of the pruning device. Utility Model Content
