Abstract
Description
Technical Field
[0001] This utility model relates to the field of grafting tool technology, and in particular to a vegetable grafting tool that integrates a knife and a needle. Background Technology
[0002] Grafting is an artificial method of plant propagation, in which a branch or bud of one plant is grafted onto the stem or root of another plant, allowing the two joined parts to grow into a single, complete plant. Grafting utilizes the plant's ability to heal after injury. There are two main grafting methods: branch grafting and bud grafting. Grafting not only allows seedless plants to reproduce rapidly but also allows the use of the superior traits of both the scion and rootstock varieties, resulting in earlier fruiting and enhanced resistance to cold, drought, and pests. Grafting is commonly used for the propagation of fruit trees, forest trees, and flowers, as well as for the seedling cultivation of melons and solanaceous vegetables. Common grafting methods include cleft grafting, approach grafting, and whip grafting.
[0003] Grafting is a method to improve the resistance of melons to adverse conditions, overcome continuous cropping obstacles, prevent wilt disease, and increase yield. Large seedling companies use grafting machines with high grafting efficiency and survival rate to complete the grafting work, while some small seedling institutions or private planting bases cannot afford the high cost of grafting machines.
[0004] In the prior art, such as the Chinese patent application CN214852943U, a grafting tool for vegetables is disclosed, including a grafting knife. The grafting knife includes at least a fixing body, which includes a collar, a fixed half-ring, and a movable half-ring connected to the fixed half-ring. The collar is connected to an intermediate body, which is provided with a cutting body. The cutting body includes a first cutting blade, which includes a cutting blade. The cutting blade is connected to a holding body, and the holding body is connected to a second cutting blade. The advantage of this utility model is that it fixes the vegetable root, thereby allowing a flat cut surface to be created.
[0005] The above-mentioned technology has achieved the effect of allowing multiple people to use it simultaneously, but there are still some shortcomings, specifically:
[0006] Traditional vegetable grafting often uses separate tools, requiring the alternating use of blades, bamboo skewers, and other individual implements. This results in a cumbersome process and time-consuming tool switching. Due to the lack of a unified positioning benchmark, it is difficult to accurately align the cut surface with the insertion hole, easily leading to misalignment or excessive gaps at the graft union, affecting the quality of the healing process. Furthermore, the sharp tools used individually lack anti-slip and restraint designs, requiring the operator to apply continuous force to maintain stability, which not only increases the strain on the hands. Utility Model Content
[0007] This utility model proposes a vegetable grafting tool that integrates a knife and needle, improving operational efficiency and precision. The force-applying unit, consisting of a pinch block and a connecting rod, combined with the anti-slip texture on the surface, allows for stable control of the tool's posture. The sliding steel needle module built into the rotating cover enables quick replacement and precise positioning, adapting to different stem thicknesses. The blade adopts a sliding connection method with a damping pad, ensuring cutting stability while reducing impact loss. The overall structure integrates cutting and drilling functions, shortening the operation process and reducing the exposure time of plant wounds. At the same time, the ergonomic layout reduces hand fatigue and helps improve the grafting survival rate, thus solving the problems mentioned in the background art.
[0008] To achieve the above objectives, the present invention adopts the following technical solution: a vegetable grafting tool integrating a knife and a needle, comprising a handle, a pinch block fixedly installed at the bottom end of the handle, a connecting rod fixedly installed at the bottom end of the pinch block, a rotating cover provided on the surface of the connecting rod, a steel needle provided inside the rotating cover, a blade provided at the top end of the handle, and an installation cover provided at the top end of the handle.
[0009] Preferably, the rotating cover is rotatably connected to the connecting rod via threads A and B, and is rotatably connected to the pinch block. The surface of the rotating cover is provided with anti-slip texture.
[0010] Preferably, an mounting block is fixedly installed at the top of the steel needle, and the mounting block is installed inside the rotating cover through a storage groove, with the steel needle and the rotating cover being slidably connected.
[0011] Preferably, the blade is slidably connected to the handle via a groove, and a damping pad is fixedly installed on the inner wall of the groove.
[0012] Preferably, the mounting cover is slidably connected to the knife handle, and a soft pad is fixedly installed on the inner wall of the mounting cover, and the soft pad is slidably connected to the knife handle.
[0013] Preferably, the surface of the knife handle is provided with a mounting groove, the surface of the knife handle is provided with a fixing block, a protective plate is fixedly installed on the right side of the fixing block, and a retaining pad is provided inside the fixing block.
[0014] Preferably, the fixing block is slidably connected to the tool holder, the retaining pad is rotatably connected to the tool holder, and the retaining pad is fixed to the surface of the tool holder through a mounting groove.
[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0016] 1. In this utility model, the blade groove, damping pad, blade, mounting cover, and soft pad improve operating efficiency and precision. The force application unit composed of the pinch block and connecting rod, combined with the anti-slip texture on the surface, can stably control the tool's posture. The sliding steel needle module built into the rotating cover enables quick replacement and precise positioning, adapting to different stem thicknesses. The blade adopts a sliding connection method with a damping pad, which ensures cutting stability and reduces impact loss. The overall structure integrates cutting and drilling functions, shortens the operation process, reduces the exposure time of plant wounds, and the ergonomic layout reduces hand fatigue, which helps to improve the grafting survival rate.
[0017] 2. In this utility model, the mounting groove, fixing block, guard plate and pad enhance the human-machine interaction performance and safety attributes of the tool. The mounting groove provides a standardized assembly benchmark for functional components. The sliding connection mechanism between the fixing block and the handle supports personalized position adjustment to adapt to different operators' hand sizes and force application habits.

[0025] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0027] Example 1: As Figures 1-4 As shown, this utility model provides a technical solution: a vegetable grafting tool with an integrated knife and needle, including a handle 1, a pinch block 2 fixedly installed at the bottom end of the handle 1, a connecting rod 3 fixedly installed at the bottom end of the pinch block 2, a rotating cover 5 provided on the surface of the connecting rod 3, a steel needle 10 provided inside the rotating cover 5, a blade 14 provided at the top end of the handle 1, and an installation cover 21 provided at the top end of the handle 1. The rotating cover 5 is rotatably connected to the connecting rod 3 through threads A4 and B7, and is rotatably connected to the pinch block 2. The surface of the rotating cover 5 is provided with anti-slip texture 6. An installation block 9 is fixedly installed at the top end of the steel needle 10. The installation block 9 is installed inside the rotating cover 5 through a storage groove 8. The steel needle 10 is slidably connected to the rotating cover 5. The blade 14 is slidably connected to the handle 1 through a knife groove 11. A damping pad 12 is fixedly installed on the inner wall of the knife groove 11. The installation cover 21 is slidably connected to the handle 1. A soft pad 23 is fixedly installed on the inner wall of the installation cover 21, and is slidably connected to the handle 1.
[0028] In this embodiment, the practical efficiency is significantly improved through integrated design and multiple humanized details. The integrated blade and needle structure integrates the cutting blade 14 and the piercing needle 10 into the same tool body. With the adjustable rotating cover 5 and the operation interface with anti-slip texture 6, the actions of opening the rootstock and inserting the scion are smooth and efficient. The blade 14 has a sliding groove 11 with damping pad 12 to ensure controllable cutting force. The mounting cover 21 has a built-in soft pad 23 to protect the blade and improve grip comfort. The steel needle 10 can be easily stored and retrieved through the storage slot 8. The threaded structure of the rotating cover 5 and the connecting rod 3 ensures that the piercing depth is adjustable. The overall solution effectively simplifies the grafting process, reduces the difficulty of operation, and improves the accuracy and efficiency of operation. It has the technical advantages of compact structure, high functional integration and excellent human-machine efficiency.
[0029] Example 2: As Figure 1 , Figure 4 , Figure 5As shown, the surface of the tool holder 1 is provided with a mounting groove 24, and a fixing block 25 is provided on the surface of the tool holder 1. A guard plate 26 is fixedly installed on the right side of the fixing block 25. A retaining pad 29 is provided inside the fixing block 25. The fixing block 25 is slidably connected to the tool holder 1, and the retaining pad 29 is rotatably connected to the tool holder 1. The retaining pad 29 is fixed to the surface of the tool holder 1 through the mounting groove 24.
[0030] In this embodiment, the addition of an adjustable fixing block 25 and a guard plate 26 significantly improves operational stability and safety. The mounting groove 24 on the surface of the handle 1, together with the sliding fixing block 25, forms a limiting mechanism, allowing the position of the guard plate 26 to be flexibly adjusted according to user needs. The built-in retaining pad 29 adopts a rotating connection design, which can adapt to different grip angles to provide anti-slip support, and can also achieve precise positioning through rotational fine adjustment. The guard plate 26, as a protective barrier, effectively isolates the blade area and avoids the risk of accidental contact. The overall structure adopts modular assembly, and both the retaining pad 29 and the fixing block 25 can be quickly disassembled and replaced, combining practicality and maintenance convenience. This allows the tool to maintain its basic functions while achieving a comprehensive improvement in grip stability, operational safety, and personalized adaptability, demonstrating the practical value of ergonomic design.
[0031] The working principle of this embodiment is as follows: Before use, pinch the fixing block 25 corresponding to the handle 1 and press it to the left to make the fixing block 25 slide from the right side of the handle 1 to the left. When the retaining pad 29 slides into the inside of the handle 1 through the mounting groove 24, the guard plate 26 can be moved to the right side of the handle 1 through the fixing block 25, thereby protecting the user's hand during use. Then, it can be used by pinching the block 2. When it is necessary to replace the steel needle 10 during use, pinch the rotating cover 5 and rotate it so that the rotating cover 5 rotates downward on the surface of the connecting rod 3 through the threads A4 and B7. When the rotating cover 5 is completely rotated out of the surface of the connecting rod 3 through the threads A4 and B7, the steel needle 10 is then pinched and pushed upward, so that the mounting block 9 slides out of the inside of the rotating cover 5 through the storage groove 8, and the steel needle 10 is also pulled out of the inside of the rotating cover 5, so as to complete the replacement of different steel needles 10 to meet different usage needs. During the rotation, the anti-slip texture 6 can prevent the rotation. If the movable cover 5 slips, when replacing the blade 14 later, pinch the mounting cover 21 and pull it to the left, causing the mounting cover 21 to slide the soft pad 23 to the left on the surface of the handle 1. Once the mounting cover 21 and the soft pad 23 have completely slid out of the surface of the handle 1, it is ready. Then pinch the blade 14 and pull it to the right, causing the blade 14 to slide to the right in the middle of the damping pad 12. Once the blade 14 has completely slid out of the damping pad 12 and the interior of the handle 1 through the blade groove 11, it is ready for replacement. Next, align the new blade 14 with the groove 11 and press it to the left, so that the blade 14 slides into the inside of the handle 1 and the damping pad 12 through the groove 11. Finally, align the mounting cover 21 with the left side of the handle 1 and press it to the right, so that the soft pad 23 slides completely into the surface of the handle 1. At this time, the soft pad 23 can fix the mounting cover 21 to the surface of the handle 1, and the mounting cover 21 clamps the blade 14 inside the handle 1, thereby preventing the blade 14 from falling off during use.
[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
