Description

Technical Field

[0001] This utility model relates to the technical field of tree pruning tools, and in particular to a multifunctional forestry tree pruning tool. Background Technology

[0002] Forestry tree pruning tools are specialized tools used for pruning and shaping trees in forestry. These tools can precisely cut branches with their sharp blades, successfully severing both thinner branches and thicker trunk branches.

[0003] In the garden, workers wield pruning shears, precisely trimming weak, crossing, and dense branches inside the tree canopy, creating smooth cuts. For thicker branches, they switch to high-pole shears, using the long handle and spring to easily cut through. Even thicker branches are cut with high-pole saws, their sharp teeth quickly severing the branches. Workers carefully control the angle and force to ensure a clean, smooth cut.

[0004] In existing technologies, some forestry tree pruning tools are used to prune trees using pruning shears or pruning saws. However, when switching from one tool to another, time is required to change the tool and adjust the operation method, which increases the time cost of pruning work and reduces work efficiency and flexibility. Therefore, in order to address the above shortcomings, a multifunctional forestry tree pruning tool is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a multifunctional forestry tree pruning tool, which aims to improve the problem that some existing forestry tree pruning tools only have a single function during use, resulting in reduced functionality and flexibility.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A multifunctional forestry tree pruning tool includes a main shear head and a rotating handle. A support handle is fixedly connected to the right side of the main shear head. An auxiliary shear head is rotatably connected to the inside of the main shear head via a pin. A reset component is fixedly connected to the side of the support handle and the rotating handle. A positioning shaft is fixedly connected to the left end of the main shear head. A ruler saw is rotatably connected inside the positioning shaft. A sliding column is slidably connected inside the ruler saw. A limit ring is fixedly connected to the outside of the sliding column. A spring is sleeved on the outside of the sliding column. Two limit openings are opened on the top side of the left end of the main shear head. A transmission plate is fixedly connected to the top side of the sliding column. Side plates are fixedly connected to both the left and right sides of the transmission plate.

[0008] As a further description of the above technical solution:

[0009] The main scissor head and the auxiliary scissor head are fixedly connected to the outside of a protective plate. A cleaning plate is slidably connected inside the protective plate. A strip plate is fixedly connected to the opposite side of each of the two cleaning plates. A positioning rod is fixedly connected to the left and right ends of the protective plate. A spring is sleeved on the outside of the positioning rod.

[0010] As a further description of the above technical solution:

[0011] The reset assembly includes two positioning posts, with the far side of the two positioning posts respectively fixedly connected to the near side of the support handle and the rotating handle, and a reset spring sleeved on the outside of the two positioning posts.

[0012] As a further description of the above technical solution:

[0013] The upper and lower ends of the reset spring are respectively fixedly connected to the side of the support handle and the rotating handle, and a right-angle rod is rotatably connected to the side of the rotating handle and the auxiliary scissor head.

[0014] As a further description of the above technical solution:

[0015] The bottom side of the first spring is fixedly connected to the top side of the limiting ring, and the top side of the first spring is fixedly connected to the inner wall of the left end of the ruler saw.

[0016] As a further description of the above technical solution:

[0017] The outer side of the ruler saw is slidably connected to the inner wall of the main shear head, and the outer side of the sliding column is slidably connected to the inside of the limiting opening.

[0018] As a further description of the above technical solution:

[0019] The outer side of the limiting ring is slidably connected to the inner wall of the ruler saw, and the bottom side of the transmission plate is in contact with the top side of the ruler saw.

[0021] The two springs are fixedly connected to the left and right ends of the strip plate, respectively, and the two positioning rods are slidably connected to the inside of the left and right ends of the strip plate, respectively.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, by releasing the tension on the side plate, the spring returns to its original position through the limiting ring and is then fixed in the limiting opening at the left end of the main shear head, allowing for quick conversion without having to switch from one tool to another, thereby improving the flexibility of the forestry tree pruning tool.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 2 to 4 This utility model provides an embodiment of a multifunctional forestry tree pruning tool, comprising a main shear head 1 and a rotating handle 4. A support handle 2 is fixedly connected to the right side of the main shear head 1 by welding, thus providing support for the main shear head 1. An auxiliary shear head 3 is rotatably connected to the inside of the main shear head 1 by a pin, which supports the main shear head 1 and the auxiliary shear head 3, allowing them to prune trees in an alternating manner. A reset assembly is fixedly connected to the side of the support handle 2 and the rotating handle 4, providing a reset force for the rotating handle 4. The reset assembly includes two positioning posts 5, with their opposite sides fixedly connected to the side of the support handle 2 and the side of the rotating handle 4 by welding, thus providing support for the two positioning posts 5. A reset spring 6 is sleeved on the outside of the two positioning posts 5, restricting the reset spring 6 so that it can be evenly stressed.

[0034] The upper and lower ends of the return spring 6 are fixedly connected to the support handle 2 and the rotating handle 4 respectively on the adjacent sides. As the rotating handle 4 rotates, it compresses the return spring 6, allowing the return spring 6 to store elastic potential energy, which then applies a force in the opposite direction to the rotating handle 4 for reset. A positioning shaft 7 is fixedly connected to the left end of the main shear head 1, secured by welding, thus providing support for the positioning shaft 7. A ruler saw 8 is rotatably connected inside the positioning shaft 7, allowing the ruler saw 8 to rotate. The ruler saw 8 is slidably connected to the inner wall of the main shear head 1, allowing it to rotate stably. A sliding column 9 is slidably connected inside the ruler saw 8, allowing it to slide stably. A limit ring 10 is fixedly connected to the outside of the sliding column 9, causing the limit ring 10 to slide synchronously during the sliding process. A spring 11 is sleeved on the outside of the sliding column 9, ensuring that it receives uniform force.

[0035] The bottom side of spring 11 is fixedly connected to the top side of limiting ring 10. During sliding, limiting ring 10 compresses spring 11, allowing it to store elastic potential energy and subsequently apply a force in the opposite direction to the limiting ring 10 for resetting. The outer side of limiting ring 10 is slidably connected to the inner wall of saw 8, ensuring stable sliding. The top side of spring 11 is fixedly connected to the inner wall of the left end of saw 8 via welding, ensuring even force distribution. Two circular limiting openings 12 are formed on the top left side of the main shear head 1. The outer side of sliding post 9 is slidably connected to the inside of the limiting openings 12, allowing it to engage inside the auxiliary shear head 3. A transmission plate 13 is fixedly connected to the top side of sliding post 9 via welding, ensuring stable sliding of sliding post 9 by the transmission plate 13. The bottom side of the transmission plate 13 contacts the top side of the saw 8, and the saw 8 provides support for the transmission plate 13. Side plates 14 are fixedly connected to both sides of the transmission plate 13, and the saw 8 slides synchronously through the two side plates 14. A right-angle rod 15 is rotatably connected to the end of the rotating handle 4 and the auxiliary scissor head 3. The right-angle rod 15 provides support, allowing the rotating handle 4 to slide and transmit force to the auxiliary scissor head 3, which then rotates.

[0036] Reference Figure 1 , Figure 2 and Figure 5 The main scissor head 1 and the auxiliary scissor head 3 are externally fixedly connected to a protective plate 16, which is fixed by welding to provide support for the protective plate 16. A cleaning plate 17 is slidably connected inside the protective plate 16. The protective plate 16 restricts the stable sliding of the cleaning plate 17, while simultaneously cleaning the surfaces of the auxiliary scissor head 3 and the main scissor head 1. A strip plate 18 is fixedly connected to the opposite side of each of the two cleaning plates 17, providing support and preventing slippage. Positioning rods 19 are fixedly connected to the left and right ends of the protective plate 16, which is fixed by welding to provide support for the positioning rods 19. The two positioning rods 19 are externally slidably connected to the inside of the left and right ends of the strip plate 18, allowing the strip plate 18 to slide stably. A second spring 20 is sleeved on the outside of the positioning rod 19, ensuring that the second spring 20 receives uniform force due to the restriction of the positioning rod 19. The two springs 20 are fixedly connected to the left and right ends of the strip plate 18 respectively. When the strip plate 18 slides, it will compress the two springs 20, so that the two springs 20 can store elastic potential energy, and then give the strip plate 18 a force in the opposite direction to reset it.

[0037] Working principle: First, by holding the support handle 2 and then squeezing the rotating handle 4, the rotating handle 4 can drive the right-angle rod 15 to slide, thereby driving the auxiliary scissor head 3 to rotate around the pin inside the main scissor head 1. This allows the auxiliary scissor head 3 and the main scissor head 1 to cut branches. At the same time, the rotating handle 4 will also squeeze the return spring 6 during the sliding process, allowing the return spring 6 to store elastic potential energy. Then, the rotating handle 4 and the right-angle rod 15 will give the auxiliary scissor head 3 a force in the opposite direction to return it to its original position, which will facilitate subsequent cutting.

[0038] Meanwhile, when facing branches that the knife cannot cut, by pulling the two side plates 14, the transmission plate 13 is driven to slide upward, thereby driving the sliding column 9 to slide. Then, the sliding column 9 will also drive the limiting ring 10 to slide and squeeze the spring 11, so that the spring 11 can store elastic potential energy. Then, the limiting ring 10 will give the sliding column 9 a counterforce to reset it. Then, the ruler saw 8 can be rotated, so that the ruler saw 8 rotates 180 degrees to the left, so that the saw teeth of the ruler saw 8 face outward. At the same time, the pulling force on the side plate 14 is released, so that the spring 11 transmits the reset force to the sliding column 9 through the limiting ring 10 and engages in the limiting opening 12 at the left end of the main shear head 1 to complete the fixation. This allows for quick conversion, so that there is no need to switch from one tool to another, thus improving the flexibility of the forestry tree pruning tool.

[0039] When the main shear head 1 and the auxiliary shear head 3 rotate alternately, they will also drive a protective plate 16 to slide and open between the main shear head 1 and the auxiliary shear head 3. During the opening process, the cleaning plates 17 on the main shear head 1 and the auxiliary shear head 3 will contact the surface of the opposite main shear head 1 or auxiliary shear head 3. At the same time, by pressing against the cleaning plate 17, the cleaning plate 17 can push the strip plate 18 to slide and squeeze the two springs 20. The two springs 20 can store elastic potential energy, so that the strip plate 18 gives the cleaning plate 17 a force in the opposite direction to clean the contact surface of the main shear head 1 and the auxiliary shear head 3, so as to avoid residual impurities affecting the trimming process and thus improve work efficiency.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
