Technical Field

[0001] This utility model relates to the field of agricultural grafting technology, specifically to a stem tip grafting device for citrus. Background Technology

[0002] Stem tip grafting of citrus is an important plant propagation technique aimed at obtaining virus-free plants and expanding propagation through commercial nurseries to improve varieties or achieve factory-scale seedling production. Generally, it involves grafting stem tip meristem containing the growth point onto a sterile rootstock.

[0003] Referring to the patent application with authorization announcement number CN217826037U, a microbud grafting tool is disclosed. This utility model uses a bud-picking knife and a rootstock-drilling knife together, which can quickly drill holes in the rootstock and quickly extract the stem tip to complete the microbud grafting work. Moreover, both the bud-picking blade and the drilling blade are detachable and can be directly replaced after wear, avoiding uneven cuts caused by blade wear due to long-term use.

[0004] However, the above-mentioned technology uses a combination of a bud-taking knife and a hole-making knife to perform bud grafting. During grafting, the knife needs to be switched. In the existing device, the currently used knife is put away and another knife is taken out for the next operation. When the knife is not in use after switching, in order to ensure safety and prevent damage to the blade, the operator needs to cover the blade with a protective cover, which is inconvenient to use and reduces grafting efficiency to a certain extent. Its practicality is generally limited. Utility Model Content

Detailed Implementation

[0022] 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.

[0023] See Figure 1-Figure 4 This utility model provides two technical solutions:

[0024] First embodiment: A stem tip grafting device for citrus, including a handle 1, and further comprising:

[0025] The grafting component 2 is set on the outside of the handle 1 for grafting the stem tip of citrus. The grafting component 2 includes a bud-cutting knife 21 fixedly installed on the left end of the handle 1 for cutting the stem tip, and a hole-making knife 24 fixedly installed on the right end of the handle 1 for making holes in the rootstock.

[0026] Protective component 3, located inside the handle 1, protects the budding knife 21 and the perforating knife 24 from damage. Protective component 3 includes slots 31 at both ends of the handle 1. A protective frame 32 for protecting the budding knife 21 and the perforating knife 24 is movably installed inside the slots 31. A limiting component is provided inside the slots 31 to fix the position of the protective frame 32. Several brushes 34 for cleaning debris from the outside of the budding knife 21 and the perforating knife 24 are fixedly installed on the top and bottom surfaces of the inner cavity of the protective frame 32. The limiting component includes a connecting frame 37 fixedly installed on the opposite side of the protective frame 32. A movable groove 38 is provided on the top surface of the connecting frame 37. A movable plate 310 is movably installed inside the movable groove 38. Springs 39 are fixedly installed on both the front and rear sides of the bottom surface of the movable plate 310. Insert rods 311 are fixedly installed on both the front and rear sides of the top surface of the movable plate 310 to fix its position. A handle 36 is fixedly installed on the top surface of the movable plate 310 to facilitate pulling the connecting frame 37. The groove 31 is located on the opposite side of the top surface. The front and rear ends are provided with second slots 312. The front and rear sides of the top surface of the slot 31 are provided with first slots 33, and the first slots 33 and the second slots 312 are the same size. The left and right sides of the top surface of the handle 1 are provided with top slots 35. The top surface of the handle 36 moves through the interior of the movable slot 38 and the top slot 35 and extends to the top surface of the handle 1. Pressing the handle 36 can drive the movable plate 310 to press down and pull the plug rod 311 out of the interior of the second slot 312 to release the restriction on the connecting frame 37. Then the connecting frame 37 can be moved to drive the protective frame 32 to move and cover the outside of the bud cutter 21 and the hole opener 24 for protection. The bottom end of the spring 39 is fixedly installed on the bottom surface of the movable slot 38. The top end of the plug rod 311 moves through the interior of the movable slot 38 and extends into the interior of the second slot 312 to fix the position of the connecting frame 37. The elastic force of the spring 39 can drive the movable plate 310 to rise and insert the plug rod 311 into the interior of the second slot 312 to fix the position of the connecting frame 37.

[0027] The protective frame 32 provides convenient protection for the budding knife 21 and the perforating knife 24. When switching between the budding knife 21 and the perforating knife 24 is required, pressing the handle 36 causes the movable plate 310 to press down, pulling the insertion rod 311 out of the second slot 312 and releasing the restriction on the connecting frame 37. Then, the handle 36 can be pulled to move the connecting frame 37, which in turn moves the protective frame 32 to cover the outside of the budding knife 21 or the perforating knife 24. While pushing, the brush 34 can clean the debris on the outside of the budding knife 21 and the perforating knife 24. Then, releasing the handle 36 allows the movable plate 310 to rise due to the elasticity of the spring 39, inserting the insertion rod 311 into the first slot 33 and fixing the position of the protective frame 32. This facilitates use, ensures the safety of the staff, and prevents damage to the budding knife 21 and the perforating knife 24, thereby improving grafting efficiency to a certain extent.

[0028] The second embodiment differs from the first embodiment in that the grafting component 2 further includes an arc-shaped groove 22 formed on the top and bottom surfaces of the handle 1. The arc-shaped groove 22 is formed in the middle of the top and bottom surfaces of the handle 1 to facilitate the worker to hold the device for grafting operations. Several rubber strips 23 to improve friction are fixedly installed on the inner side of the arc-shaped groove 22. Side blades 25 to facilitate drilling are fixedly installed on both the front and rear sides of the top surface of the drilling knife 24. The several rubber strips 23 are linearly and evenly distributed inside the arc-shaped groove 22 to improve friction and thus improve the stability of the device when in use.

[0029] The bud-cutting knife 21 and the hole-making knife 24 are designed for easy switching between use by the staff. When in use, the bud-cutting knife 21 and the hole-making knife 24 can be switched by simply turning the handle 1. At the same time, the rubber strip 23 can increase the friction between the device and the staff's fingers, making it easier to cut stem tips and make holes for grafting. The structure is simple and practical.

[0030] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.

[0031] In use, the user picks up the handle 1 and makes a hole in the rootstock using the piercing knife 24 and the side blade 25. Then, pressing the handle 36 causes the movable plate 310 to press down, pulling the insertion rod 311 out of the second slot 312 and releasing the restriction on the connecting frame 37. Then, the user can pull the handle 36 to move the connecting frame 37, which in turn moves the protective frame 32 and covers the outside of the piercing knife 24. While pushing, the user can use the brush 34 to clean the debris on the outside of the piercing knife 24. Then, releasing the handle 36 allows the movable plate 310 to rise due to the elasticity of the spring 39, inserting the insertion rod 311 into the first slot 33 and fixing the position of the protective frame 32. Finally, the user uses the bud-cutting knife 21 to cut off the stem tip for grafting.
