Description

Technical Field

[0001] The utility model relates to the technical field of pruning tools, in particular to a pruning tool capable of adjusting the pruning angle. Background Art

[0002] Forestry engineering refers to the application of various engineering technologies to the cultivation, development and utilization of forest resources and the processing of forest products based on the principle of efficient utilization and sustainable development of forest resources. In the early stage of forestry felling, trees are usually pruned to make felling work smoother. Most existing technologies use manual hand-held scissors to prune trees. When the position to be pruned is too high or too far from where people can stand, ordinary pruning tools cannot be used, and workers are prone to fatigue when holding pruning tools for a long time.

[0003] In the prior art, a Chinese patent document with a publication number of CN215122779U is proposed to solve the above technical problems. The technical solution disclosed in the patent document is as follows: a pruning device for forestry felling, including a mounting block, a lifting mechanism is provided at the bottom of the mounting block, a base is provided at the bottom of the lifting mechanism, a mounting rod is provided on one side of the mounting block, a mounting tube is provided on the mounting rod, and a first hydraulic rod is provided in the mounting tube; a first mounting frame and a second mounting frame are provided at one end of the mounting tube, a mounting seat is provided in the first mounting frame, a flat gear is provided on one side of the mounting seat, and a pruning mechanism is provided on the other side; a threaded rod is passed through the second mounting frame to mesh with the flat gear, and a transmission motor is provided at one end of the threaded rod; a control panel is provided on one side of the mounting block. The pruning mechanism prunes the plants, and the angle of the pruning mechanism can be adjusted by controlling the rotation of the transmission motor. The lifting mechanism is convenient for adjusting the height of the pruning mechanism, which is suitable for plants of different heights. The first hydraulic rod can adjust the distance between the pruning mechanism and the staff, which is convenient for pruning the places that cannot be reached by hands, and the base is convenient for placement to avoid fatigue of the staff.

[0004] In order to solve the problem that ordinary pruning tools cannot be used when the pruning position is too high or too far away from the position where people can stand, and the staff are very prone to fatigue when holding the pruning tools for a long time, the existing technology adopts the method of setting a lifting mechanism and a hydraulic rod to deal with it. However, the pruning angle adjustment is limited, which leads to the problem that some tricky angles cannot be pruned, affecting the growth of plants. Utility Model Content
