Description

Technical Field

[0001] The utility model relates to the technical field of pruning shears, in particular to multifunctional pruning shears for sour jujube grafting. Background Art

[0002] The wild jujube tree is a woody plant belonging to the shrub family. It is a plant with many treasures. In order to make the wild jujube tree grow better, the staff will prune the wild jujube tree to facilitate the grafting of the wild jujube tree. Pruning shears are needed for pruning and grafting. Pruning shears are a kind of pruning tool used in gardening, flowers and other work areas. They are used to prune the parts of flowers, plants, branches and leaves that are too lush or affect other facilities in the site to ensure the overall aesthetics of the site. When using the pruning shears, force is applied to the pruning shears through the force arm to prune the branches and leaves. Because the branches of the wild jujube tree are relatively hard, the staff need to use a lot of strength when performing grafting and pruning, which can easily cause the staff to lose too much physical strength and greatly slow down the pruning speed. For this reason, we propose multi-functional pruning shears for wild jujube grafting. Utility Model Content
