Description

Technical Field

[0001] This utility model relates to the field of desprouting tools, and in particular to a tool for desprouting grafted poplar seedlings. Background Technology

[0002] In the cultivation of grafted poplar seedlings, timely removal of suckers is a crucial and necessary task. Suckers compete with grafted seedlings for nutrients and water, affecting their normal growth and development, and consequently negatively impacting the final quality and yield of the poplar timber. Therefore, an efficient and practical tool for removing suckers from grafted poplar seedlings is essential for the poplar planting industry. It can not only improve the efficiency of sucker removal but also reduce the labor intensity of workers. In actual poplar planting environments, sucker removal work usually needs to be carried out under different terrain and spatial conditions, which requires the tool to have good operability and portability to adapt to various complex working scenarios.

[0003] Currently, most poplar grafting seedling desprouting tools on the market use traditional mechanical structures. Some tools employ a simple scissor-like structure, cutting the suckers by manually opening and closing the blades. These tools rely primarily on manual pressure, using leverage to increase cutting force. Others use a blade-type structure, fixing the blade to the handle and using its sharp edge for cutting. These tools are conventionally designed and typically do not consider the specific and complex nature of desprouting. During operation, workers need to expend considerable effort to complete the cutting action, and it is particularly difficult to handle suckers growing in concealed locations. Furthermore, these tools are inconvenient to store and carry, often requiring additional protective measures to prevent blade damage.

[0004] However, existing tools for removing suckers from grafted poplar seedlings have a serious problem in practical use: they are not easy to store. Since the blades are usually exposed, they can easily cause cuts when not in use. This is especially true when workers frequently move between work positions or are carrying the tools, as the exposed blades increase the risk of injury. Furthermore, existing storage methods are often complex and require considerable time and effort, which not only reduces work efficiency but also leads to workers neglecting to store the tools in a hurry, potentially causing accidents. This inconvenient storage problem seriously affects the safety of the tools and causes considerable inconvenience to the removal of suckers from grafted poplar seedlings. Therefore, a new tool for removing suckers from grafted poplar seedlings is proposed to solve these problems. Utility Model Content

[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 Figure 1 - Figure 3 This utility model provides an embodiment of a poplar grafted seedling sucker removal tool, comprising a handle 1 made of high-strength engineering plastic. This material is not only lightweight, making it easy to hold for extended periods, but also possesses good wear resistance and impact resistance, enabling it to adapt to complex outdoor working environments. The handle 1 has a hollow internal structure, in which a blade 2 is slidably connected. The blade 2 is slidably connected inside the handle 1, and a connecting block 3 is provided on the outer wall of the blade 2. A shrinkage component is provided inside the handle 1.

[0034] The retraction assembly includes a slider 10, whose outer wall is slidably connected to the inside of the tool holder 1. The tool holder 1 has a retraction groove 7, a sliding groove 4, and a retaining groove 8 inside. The sliding groove 4 provides a track for the sliding of the push post 6, and its dimensions are adapted to the push post 6 to ensure stable sliding within it. The retaining groove 8 is used to fix the retaining post 12, ensuring the stability of the tool 2 when extended for use. The movable groove 9 provides space for the movement of the locking post 12, allowing the locking post 12 to switch between different positions. The movable groove 9 is provided inside the tool holder 1. The sliding block 10 is provided with a disassembly and assembly assembly. The sliding block 10 is provided with a lifting groove 11. The push post 6 is slidably connected inside the sliding block 10. The outer wall of the push post 6 is slidably connected inside the sliding groove 4. The locking post 12 is fixedly connected to the outer wall of the push post 6. The outer wall of the locking post 12 is slidably connected inside the locking groove 8. The bottom of the locking post 12 is provided with a spring-rebound assembly, which includes a limiting disc 13 and a spring 14. The top of the limiting disc 13 is fixedly connected to the bottom of the locking post 12. The spring 14 is provided inside the sliding block 10. The top of the spring 14 is fixedly connected to the bottom of the limiting disc 13. The bottom of the spring 14 is fixedly connected to the inside of the sliding block 10.

[0035] Specifically, when the tool 2 needs to be used, the operator can press the push post 6, which is tightly connected to the locking post 12. At the moment the push post 6 is pressed, the locking post 12 will slide inside the lifting groove 11. As the locking post 12 moves, it will gradually slide from the original embedded groove 8 to the moving groove 9. At the same time, the locking post 12 is also connected to the limiting disc 13. Therefore, during the lifting and lowering of the locking post 12, the limiting disc 13 will also move synchronously, thereby compressing the spring 14 below. During this process, the push post 6 is continuously pushed, thereby driving the connected slider 10 to slide along the predetermined track. When the slider 10 slides to the appropriate length required by the operator, the operator can release the push post 6. At this time, the previously compressed spring 14 will quickly rebound, and with its own elastic force, it will drive the locking post 12 to quickly return to the groove 8, accurately fixing the slider 10 and ensuring the stability of the tool 2 in the extended state, thereby conveniently realizing the retraction operation of the tool 2.

[0036] Reference Figure 1 , Figure 3 and Figure 4 The assembly / disassembly components include a fixed post 15, the top of which is fixedly connected to the inside of a slider 10. A connecting block 3 is slidably connected to the inside of the slider 10. A connecting post 17 is slidably connected inside the fixed post 15, and a pressing post 5 is fixedly connected to the top of the connecting post 17. The surface of the pressing post 5 is specially treated with anti-slip textures for easy pressing by the operator's fingers. When the operator needs to change the tool 2, they only need to gently press the pressing post 5 to start the entire assembly / disassembly process. A conical block 16 is fixedly connected to the outer wall of the connecting post 17. The conical block 16 is also made of stainless steel and its shape is carefully designed to be conical. The outer wall of the conical block 16 can slide smoothly and tightly inside the fixed post 15, and its function is to limit and unlock the ball 20. When the conical block 16 slides upward, it gradually releases the restriction on the ball 20; when it slides downward, it limits the ball 20. The outer wall of the conical block 16 is slidably connected to the inside of the fixed post 15. The outer wall of the connecting post 17 is fixedly connected to the limiting ring 19. The outer wall of the limiting ring 19 is slidably connected to the inside of the fixed post 15. The outer wall of the fixed post 15 is fitted with a second spring 18. The top of the second spring 18 is fixedly connected to the bottom of the limiting ring 19. The bottom of the second spring 18 is fixedly connected to the inner wall of the fixed post 15. The ball 20 is provided inside the fixed post 15. A limiting groove 21 is opened inside the fixed post 15. The outer wall of the ball 20 is slidably connected to the inside of the limiting groove 21. The outer wall of the ball 20 is slidably connected to the inside of the connecting block 3.

[0037] Specifically, in the process of removing suckers from grafted poplar seedlings, the blade 2 will inevitably become dull after prolonged use, requiring replacement. The operator can press the pressing post 5, which is connected to the connecting post 17. When the pressing post 5 is pressed, the connecting post 17 will slide, and the limiting ring 19 on the connecting post 17 will also move, compressing the spring 18. As the connecting post 17 slides, the connected conical block 16 will also slide synchronously. When the conical block 16 slides to a certain position, it will release... Except for limiting the ball 20, the ball 20 can slide freely inside the limiting groove 21. At this time, the operator can slide the connecting block 3 out from the slider 10 to remove the dulled tool 2. After removal, the connecting block 3 corresponding to the new tool 2 is placed inside the slider 10. Then, the pressing column 5 is released. At this time, the compressed spring 18 will rebound, driving the connecting column 17 back to its original position. The conical block 16 at the end of the connecting column 17 limits the ball 20 again, thereby fixing the connecting block 3 and realizing the convenient replacement of the tool 2.

[0038] Working principle: When the tool 2 needs to be used, the push column 6 can be pressed. The push column 6 drives the locking column 12 to slide inside the lifting groove 11, and then slides it from inside the locking groove 8 to inside the moving groove 9. At the same time, the locking column 12 drives the limiting disc 13 to rise and fall, thereby compressing the spring 14, which can push the push column 6. The push column 6 drives the slider 10 to slide. After reaching the appropriate length, the push column 6 can be released. The spring 14 rebounds and drives the locking column 12 back into the locking groove 8, fixing the slider 10 and ensuring the stability of the tool 2, thus facilitating the retraction of the tool 2.

[0039] Additionally, when the tool 2 becomes stuck due to prolonged use, the pressing post 5 can be pressed. This causes the connecting post 17 to slide, which in turn moves the limiting ring 19 to compress the spring 18. The connecting post 17 then causes the conical block 16 to slide, releasing the limiting position on the ball 20. This allows the ball 20 to slide within the limiting groove 21, enabling the connecting block 3 to slide out of the slider 10 for replacement. After replacing the ball 3, the new block 3 is placed inside the slider 10. Then, the pressing post 5 is released, and the spring 18 returns, causing the connecting post 17 to return to its original position, thus limiting the ball 20 and securing the connecting block 3. This facilitates the convenient replacement of the tool 2.

[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.
