Detailed Implementation

[0023] 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.

[0024] Please see Figure 1-4A precise positioning tool for grafting jujube includes a grafting device, a protective shell 1, and a protective device. The grafting device includes a handle 2, a support base 3, a fixed blade 4, an electric telescopic rod 5, a grafting blade 6, a protective handle 7, a start button 8, and a storage battery 9. The protective handle 7 is installed on one side wall of the upper part of the handle 2. The support base 3 is installed on the top of the protective handle 7. The fixed blade 4 is installed on the top of the support base 3. The electric telescopic rod 5 is installed on the top of the handle 2. The grafting blade 6 is hinged to the output end of the electric telescopic rod 5. The grafting blade 6 is rotatably connected to the fixed blade 4. The start button 8 is installed on the side wall of the handle 2 near the protective handle 7. The storage battery 9 is installed inside the handle 2. The protective shell 1 is installed on the side wall of the handle 2 through the protective device. In this embodiment, before using the grafting device, the protective shell 1 is adjusted to be below the handle 2 using the protective device. The protective shell 1 is in its initial position (usually covering the fixed blade 4 and the grafting blade). To prevent accidental injury, manually hold handle 2, then move the fixed blade 4 to the desired grafting position, and adjust it to a suitable angle so that the grafting blade 6 is aligned with the cutting position. After determining the cutting position, press the start button 8, and the electric telescopic rod 5 will start working, pushing the grafting blade 6 upward along the preset trajectory to cut the branch. The grafting blade 6 and the fixed blade 4 are rotatably connected, and the grafting blade 6 will rotate around the rotation point of the fixed blade 4 as the center point. This means that they can work in coordination to ensure the consistency of the cutting angle and depth, achieve precise cutting, ensure grafting quality, and help improve the success rate of grafting. Compared with the traditional manual grafting method, this tool uses the electric telescopic rod 5 to automatically complete the cutting action, which greatly improves the work efficiency. Just align it with the position to be cut and press the start button 8 to start the cutting, which is convenient for the subsequent grafting work. Since the cutting work is completed by electric components, it reduces the physical consumption of the operator and is especially suitable for long-term work.

[0025] In practical use, to further facilitate the protection of the fixing knife 4 and the grafting knife 6, in this embodiment, the protective device includes a rectangular groove 10, a threaded rod 11, a slider 12, and a drive motor 13. The rectangular groove 10 is vertically formed on the front side wall of the handle 2. The threaded rod 11 is rotatably installed in the rectangular groove 10. The drive motor 13 is installed through the top of the threaded rod 11 and threaded onto the top wall of the handle 2. The slider 12 is threaded onto the threaded rod 11. The side wall of the slider 12 is fixedly connected to the inner side wall of one end of the protective shell 1. Before using the grafting device, ensure that the protective device is in a suitable position. When the protective shell 1 is in its initial position, it typically covers the fixed blade 4 and the grafting blade 6 to prevent accidental injury. When grafting is required, the drive motor 13 rotates the threaded rod 11, causing the slider 12 to move up and down along the rectangular groove 10. The protective shell 1 descends, exposing the fixed blade 4 and the grafting blade 6 for easy operation. After the cutting and grafting actions are completed, the drive motor 13 raises the protective shell 1 again to cover the blades, ensuring safety. The presence of the protective shell 1 effectively prevents users from coming into contact with the sharp blades when not in use, reducing the risk of cuts. It also provides protection during equipment transportation and storage.

[0026] In actual use, the adjustment of the protective shell 1 is further guided. In this embodiment, the rear side wall of the grip 2 is vertically provided with a guide groove 14. A guide rod 15 is fixedly installed in the guide groove 14. A guide block 16 is slidably installed on the guide rod 15. The guide block 16 is fixedly connected to the inner side wall of the protective shell 1 away from the slider 12. Through the design of the guide rod 15 and the guide block 16, it is ensured that the protective shell 1 maintains a straight line movement when moving up and down, avoiding any possible deviation or swing, thereby improving the accuracy of the position adjustment of the protective shell 1. The guide rod 15 provides additional support and stability for the movement of the protective shell 1. In particular, when the protective shell 1 is subjected to external forces (such as accidental collisions), it can effectively prevent it from tilting or derailing.

[0027] Preferably, in this embodiment, the protective shell 1 is elliptical and has an opening 17 on the side near the protective handle 7. The elliptical design can better adapt to the overall shape and structure of the tool, so that the protective shell 1 can protect the knife while minimizing its own size for easy hand operation. The opening 17 is designed mainly to avoid physical interference between the protective shell 1 and the protective handle 7 during the up-and-down adjustment process.

[0028] Preferably, in this embodiment, the bottom wall of the grip 2 is equipped with a base 18, which can provide a stable foundation when the position of the protective shell 1 is adjusted by the protective device.

[0029] Preferably, in this embodiment, the drive motor 13 is a servo motor. Servo motors have fast response speed and good acceleration performance, which makes them very suitable for application scenarios that require frequent start and stop. In agricultural or gardening tools, such characteristics help improve work efficiency and reduce waiting time.

[0030] In actual use, to further facilitate the supply of power to the energy storage battery 9, in this embodiment, a charging port 19 is provided on the lower side wall of the end of the grip 2 near the protective handle 7. The charging port 19 facilitates the replenishment of power to the energy storage battery 9. The convenient charging design allows users to replenish energy in a timely manner, ensuring that the device is always in the best condition and extending the continuous working time. This is very useful for scenarios that require long-term operation and helps to improve work efficiency.
