Description

Technical Field

[0001] The utility model belongs to the technical field of pruning tools, in particular to a forest pruning tool. Background Art

[0002] With the continuous development of urban greening and garden construction, tree pruning has become an important measure to maintain the beauty of the urban environment and ensure the healthy growth of trees. Although traditional tree pruning tools such as scissors and saws can complete basic pruning tasks, they are inefficient and pose safety risks when dealing with high branches or thicker branches. In addition, existing tree pruning tools often have single functions and cannot meet the needs of multiple operations such as trimming, chopping and sawing, which requires workers to carry multiple tools, increasing labor intensity and operation complexity. Therefore, it is necessary to develop a multifunctional tree pruning tool to improve the efficiency and safety of tree pruning while reducing the labor burden of workers. Utility Model Content

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment one:

[0028] See also Figure 1-6 As shown, the utility model is a forest pruning tool, comprising a rod body 1 and a tool head 2 installed at the end of the rod body 1. The tool head 2 includes an internal thread joint 21 threadedly connected to the end of the rod body 1. A coaxially arranged round rod 22 is fixed to the upper end of the internal thread joint 21. A hook 23 and a J-shaped plate 24 with an opening downward are fixed to the outer wall of the round rod 22, and the hook 23 and the J-shaped plate 24 are located on the symmetrical side of the axis of the round rod 22. Two rectangular grooves 25 are provided on the inner arc surface of the J-shaped plate 24. A blade 3 is installed in each of the two rectangular grooves 25, and the blade ends of the two blades 3 are arranged in a V shape. When in use, the J-shaped plate 24 is hooked on the upper side of the rod body of the branch to be removed, and the branch rod body slides into the V-shaped space formed by the blade ends of the two blades 3. The rod body 1 is held downward by applying force below to cut the branch rod body out of its original position, which is fast and convenient for removing high-altitude branches. In order to facilitate the cleaning of tree branches at different altitudes, the rod body 1 adopts the style of a multi-section telescopic rod.

[0029] In order to facilitate the fixing of the positions of the two blades 3 and the replacement of the blades 3, the side of the J-shaped plate 24 is provided with a threaded through hole 26 connected to the rectangular groove 25, and each rectangular groove 25 is connected to at least two threaded through holes 26. The threaded through hole 26 is internally threaded with a top screw 5, and the tip of the top screw 5 presses the blade 3 to position it.

[0030] The hook 23 is mainly used to adjust the position of branches at a high position of the tree. In order to prevent the hook 23 from causing damage to the branches, the cross section of the hook 23 is a circular structure.

[0031] In order to clean the branches below the main trunk, an internal threaded hole is provided at the top of the round rod 22. A top cutter 4 is connected to the internal threaded hole. The top cutter 4 includes a semi-threaded column 41 threadedly connected to the internal threaded hole. A V-shaped plate 42 is fixed to the top surface of the semi-threaded column 41. A V-shaped cutting blade 43 is provided on the inner side of the V-shaped plate 42 relative to the end surface. The surface where the V-shaped cutting blade 43 is located is perpendicular to the surfaces where the V-shaped blades of the two blades 3 are located. When in use, the V-shaped cutting blade 43 cuts the branches from the bottom of the branches upward. For thicker branches, the V-shaped cutting blade 43 can also be used to cut them multiple times.

[0032] In order to achieve the purpose of chopping branches, one half of the end surface of the V-shaped plate 42 is provided with an integrally connected extension 44. The outer end surface of the extension 44 and the outer end surface of the V-shaped plate 42 are provided with a blade 45. When the rod body 1 is swung on the ground, the blade 45 can chop the branches.

[0033] In order to achieve the purpose of sawing branches, the blade 45 has V-shaped notches arranged continuously along its length. The V-shaped notches of the blade 45 are attached to the branches, and the rod body 1 can be pulled back and forth on the ground to saw off the branches.
