Description

Technical Field

[0001] This utility model relates to the field of garden seedling pruning technology, specifically to a ratchet shear for pruning round forest seedlings. Background Technology

[0002] With the continuous progress and development of the landscaping and horticulture industry, the demand for efficient and safe pruning tools is increasing. In modern landscape management, pruning is a frequent and important task, affecting not only the healthy growth of plants but also the overall aesthetics of the garden. Therefore, choosing an efficient and labor-saving pruning tool is crucial. Using ratchet shears is an ideal choice for pruning because its ratchet mechanism allows for the accumulation of force during the cutting process, making pruning easier, especially suitable for pruning thicker branches.

[0003] However, despite their excellent performance in pruning, existing ratchet shears for garden pruning still have some shortcomings in practical use. One major problem is the lack of a locking mechanism. When the ratchet shears are subjected to external impact or improper operation, the blades may accidentally open or close. This can not only damage the tool itself but also cause serious injury to the user's hands. This risk is particularly pronounced when working at heights or pruning thicker branches.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0024] 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.

[0025] According to an embodiment of the present invention, a ratchet shear for pruning round forest seedlings is provided.

[0026] Example 1

[0027] like Figures 1-4As shown, the ratchet shears for pruning roundwood seedlings according to an embodiment of the present invention include a ratchet shear body 1. The ratchet shear body 1 consists of a first handle 2, a second handle 3, a first blade 4, and a second blade 5. The first blade 4 and the second blade 5 are rotatably connected. The first handle 2 is connected to the first blade 4, and the second blade 5 is connected to the second handle 3. Limiting rods 26 are provided on the first handle 2 and the second handle 3. A limiting plate 6 is provided on the inner side of the first handle 2, and a limiting groove 7 is provided inside the second handle 3. The opening size of the limiting groove 7 is slightly larger than the size of the limiting plate 6, so that the limiting plate 6 can smoothly enter the limiting groove. Inside the groove 7, the limiting plate 6 has a first through hole 8, and the limiting groove 7 has a second through hole 9. The first through hole 8 and the second through hole 9 are matched. The top of the limiting groove 7 has a cylinder 10, and the inner and outer sides of the cylinder 10 have a moving rod 11. One end of the moving rod 11 is connected to the pull plate 12, and the outer side of the cylinder 10 has a telescopic spring 13. One end of the telescopic spring 13 is connected to the pull plate 12, and the other end is connected to the limiting groove 7. The moving rod 11 is connected through the first through hole 8 and the second through hole 9. The bottom of the limiting groove 7 is fixedly connected to a fixing groove 14, and one end of the moving rod 11 is connected to the fixing groove 14 through a magnet 15. With the above scheme, when it is necessary to lock the ratchet shear, by pulling the pull plate 12, the moving rod 11 is moved upward, and it contacts the limiting rod 26 on the first handle 2 and the second handle 3, ensuring that the handle is in the closed state. At this time, the limiting plate 6 is placed inside the limiting groove 7, and the first through hole 8 and the second through hole 9 are aligned. When the pull plate 12 is released, the moving rod 11 is driven to move down under the action of the telescopic spring 13, so that the moving rod 11 passes through the limiting groove 7 and is placed inside the fixed groove 14. The moving rod 11 is further fixed by the attraction force generated by the magnet 15, which can effectively prevent accidental opening and closing and improve the safety and reliability of the tool.

[0028] like Figures 1-4As shown, the bottom end of the second handle 3 is fixedly connected to a mounting groove 16. The mounting groove 16 is provided with a rotating shaft 17. A suspension rope 18 is connected to the rotating shaft 17. A hook 19 is connected to the bottom end of the suspension rope 18. One end of the rotating shaft 17 passes through the mounting groove 16 and is connected to the rotating plate 20. A fixing bracket 21 is provided on the outside of the rotating plate 20. The fixing bracket 21 is fixedly connected to the mounting groove 16. The fixing bracket 21 is provided with a threaded hole 22. A screw 23 is threadedly connected inside the threaded hole 22. One end of the screw 23 is connected to the abutment plate 24. The abutment plate 24 abuts against the rotating plate 20. The bottom end of the mounting groove 16 is provided with a round hole 25. With the above solution, when the hook 19 is needed for suspension, rotating the screw 23 moves the abutment plate 24 away from the rotating plate 20. The rotating plate 20 is no longer restricted by the abutment plate 24 and can rotate normally. At this time, the user can pull the hook 19 to extend the suspension rope 18 wound on the rotating shaft 17. The extension length of the suspension rope 18 can be adjusted according to actual needs, allowing the ratchet shears to be suspended at fixed points at different heights and positions. This design not only improves the portability of the tool but also increases its flexibility of use. When the suspension rope 18 extends to a suitable length, the user can reverse the rotation of the screw 23 to move the abutment plate 24 into contact with the rotating plate 20, thereby stopping the rotation of the rotating shaft 17. Specifically, when the screw 23 is reversed, the screw 23 drives the abutment plate 24 towards the rotating plate 20 through threaded transmission until the abutment plate 24 is in close contact with the rotating plate 20. In this way, the rotating shaft 17 is fixed and cannot continue to rotate, thus ensuring that the length of the suspension rope 18 remains unchanged.

[0029] In summary, by employing the technical solution described above, a locking assembly can be constructed using components such as the limiting plate 6, limiting groove 7, moving rod 11, pull plate 12, and telescopic spring 13. These components cooperate to form a complete locking mechanism, effectively preventing accidental opening and closing of the ratchet shears during use and ensuring the stability and safety of the handle in the closed state. In actual use, even under external impact or improper operation, the ratchet shears will not open or close accidentally, thus protecting the operator's safety. Furthermore, by setting a magnet 15 between the moving rod 11 and the fixed groove 14, the magnet 15 generates additional attraction in the locked state, making the moving rod 11 more firmly fixed in the limiting groove 7, thereby further improving the stability of the lock. In addition, a rotating shaft 17 and a suspension rope 18 are set in the mounting groove 16, allowing the user to hang the ratchet shears on a belt or other fixed point for easy carrying and to prevent the tool from falling. In actual use, especially when working at height or moving, the suspension rope 18 can effectively prevent the ratchet shears from falling accidentally, thereby protecting the safety of the personnel below and also avoiding damage and loss of the tool.
