Description

Technical Field

[0001] This utility model specifically relates to a pruning device for grape cultivation, belonging to the technical field of grape cultivation pruning tools. Background Technology

[0002] Grape cultivation requires frequent pruning of the vines and branches. Existing pruning devices are mostly similar to scissors, which can only prune up to the height that workers can reach. To prune higher vines or branches, ladders are needed, which increases the labor intensity of the workers.

[0003] For example, the announcement number is CN208609455U, which discloses a pruning shear for grape cultivation. This utility model relates to the field of pruning tools, and more particularly to a pruning shear for grape cultivation. It includes a pruning shear body, a first blade at the upper left end of the pruning shear body, a second blade and a third blade at the lower left end of the pruning shear body, a T-shaped slider at the right end of the first blade, and T-shaped slides at the right ends of the second and third blades. The pruning shear body has two handles at the right end, and T-shaped slides are also provided at the left ends of the two handles. A first spring is provided between the two handles, and a groove is opened on the surface of each of the two handles. A pull rod is inserted into each of the two handles, and a second spring is provided at the left end of each of the two pull rods. A first fixing rod is provided on one side of each of the two pull rods. This device is simple and easy to operate, and the blades can be adjusted according to the size of the grape branches. It is convenient and easy to carry when pruning small branches. When pruning large branches, the blades are adjusted and the pull rods are extended, which saves effort during pruning.

[0004] However, in actual use, it is inconvenient to prune taller branches or vines. If it is necessary to prune high branches, ladders and other tools are required, which increases labor costs. Furthermore, it is not convenient to prune surrounding branches flexibly when pruning high branches. Also, branches pruned at high places may fall directly, posing a risk of injuring workers, making it inconvenient to use. Utility Model Content
