Description

Technical Field

[0001] This utility model relates to the field of forest tree cultivation equipment technology, and in particular to a multifunctional fixing clip for forest tree grafting. Background Technology

[0002] Tree grafting is a method of artificial vegetative propagation of plants. It involves attaching a branch or bud of one plant (scion) to the stem or root of another plant (rootstock), combining them into a single, complete plant. For example, grafting a branch of a high-quality fruit tree variety onto a adaptable wild plant rootstock combines the advantages of both. Utilizing the wound-healing ability of plants, the cambium layers of the scion and rootstock at the wound sites approach and tighten, promoting cell proliferation and healing to form a vascular tissue connection. The main factor affecting grafting success is the compatibility between the scion and rootstock, followed by grafting technique and subsequent management. Generally, the closer the kinship between the plants, the stronger the compatibility, and the higher the grafting success rate. Common methods include branch grafting and bud grafting, specifically cleft grafting, whip grafting, tongue grafting, bark grafting, and shield bud grafting, among others. Different methods are suitable for different types of economic forest trees and specific production needs.

[0003] In the utility model patent with patent publication number CN218353376U, soft adhesive 13 is glued to the inclined surfaces of two clamping blocks 11, and then the scion is inserted into the rootstock. Then, the handle 2 of the device is held, and by squeezing the two handles 2, the first elastic connector 12 and the second elastic connector 22 are deformed, and the two clamping blocks 11 open. Then, the clamping slots of the two clamping blocks 11 approach the binding position. After releasing the squeezed handle 2, the first elastic connector 12 and the second elastic connector 22 cooperate with the clamping blocks 11 to rebound and retract, so that the two clamping blocks 11 clamp the rootstock and scion. Although this method can complete a simple limiting treatment, in actual use, the above-mentioned clamping blocks are in a suspended state, and only the clamping force on both sides is used to clamp the grafting point. It is easy to deviate after being touched, which will cause the grafting point to shift, affecting the grafting survival rate. At the same time, because it is in a suspended state, it cannot perform a stable clamping operation on the grafting point, which is not conducive to practical use.

[0004] Therefore, it is necessary to provide a multifunctional fixing clip for grafting trees to solve the above-mentioned technical problems. Utility Model Content

[0005] In response to the above situation and to overcome the defects of the existing technology, this utility model provides a multi-functional fixing clip for grafting trees. In the previous technical solution, the clamping block was in a suspended state and relied solely on the clamping force on both sides to clamp the grafting point. This was prone to displacement after being touched, which would cause the grafting point to shift and affect the grafting survival rate. At the same time, because it was in a suspended state, it could not perform a stable clamping operation on the grafting point, which was not conducive to practical use.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A multi-functional fixing clamp for grafting trees includes: a limiting plate, a clamping plate, and an auxiliary rod;

[0008] The limiting plate is a horizontally placed U-shaped structure with a positioning hole in its middle section. The positioning hole is an internally threaded hole, and a fixing bolt is installed in the positioning hole. Pull holes are provided on both sides of the open end of the limiting plate. A clamping plate is placed inside the limiting plate. A limiting strip is installed on the side of the clamping plate facing the limiting plate. A limiting frame is installed on both sides of the clamping plate. The side of the extended end of the limiting plate is inside the limiting frame. A fixing hole is provided in the middle of both sides of the clamping plate. The fixing hole is an internally threaded hole.

[0009] In one embodiment, the inner ring of the pull hole is smoothed by grinding, and an annular rubber gasket is installed inside the pull hole.

[0010] In one embodiment, multiple positioning holes are spaced apart, and the spacing between adjacent positioning holes is set according to the diameter range of the tree, so that the whole device can be adapted to grafting operations of trees of different sizes.

[0011] In one embodiment, the top surface of the arc-shaped end of the limiting plate is provided with an arc-shaped eave, the top surface of the arc-shaped eave is an arc-shaped structure that expands outward, and the upper dimension of the arc-shaped eave is larger than the lower dimension.

[0012] In one embodiment, a connecting rod is installed on the right side of the clamping plate, and an installation tube is installed at the extended end of the connecting rod. The installation tube has an internally threaded tube structure, and an auxiliary rod is installed inside the installation tube. The upper part of the auxiliary rod is a threaded section, and the bottom of the auxiliary rod is a tapered rod.

[0013] The beneficial effects of this utility model are as follows:

[0014] (1) By setting the arc-shaped eaves, the soft rubber can be bonded to the lower part of the inner arc surface of the limiting plate during use, so that the limiting plate still has adhesiveness. After the limiting plate and the clamp are installed, sterile cotton is stuffed into the arc-shaped eaves. The sterile cotton is made of medical cotton and disinfectant, which can improve the protection of the grafting position, isolate external rainwater and impurities as much as possible, improve the survival rate of grafting, and the arc-shaped eaves can facilitate manual replacement of sterile cotton, further improving the protection effect of the grafting position.

[0015] (2) After the limiting plate and clamping plate are installed, the auxiliary rod is inserted into the installation tube from top to bottom. When the threaded section of the auxiliary rod contacts the installation tube, the auxiliary rod is turned so that the auxiliary rod and the installation tube are threadedly engaged. At the same time, the cone rod is driven into the ground. The auxiliary rod can provide auxiliary support for the limiting plate and clamping plate, thereby improving the functionality of the overall equipment. When grafting small-diameter trees, there is no need to use the auxiliary rod. When grafting medium and large-diameter trees, the use of the auxiliary rod makes the overall equipment more stable.

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments.

[0022] like Figures 1-2 As shown, the present invention provides a multi-functional fixing clip for grafting trees, comprising: a limiting plate 1, a clamping plate 2, and an auxiliary rod 3;

[0023] like Figures 1-4As shown, the limiting plate 1 is a horizontally placed U-shaped structure. A positioning hole 11 is provided in the middle section. The positioning hole 11 is an internally threaded hole, and a fixing bolt 12 is installed inside the positioning hole 11. Pull holes 13 are provided on both sides of the open end of the limiting plate 1. A clamping plate 2 is placed inside the limiting plate 1. A limiting strip 23 is installed on the side of the clamping plate 2 facing the limiting plate 1. Limiting frames 21 are installed on both sides of the clamping plate 2. The side of the extended end of the limiting plate 1 is inside the limiting frame 21. Fixing holes 22 are provided in the middle of both sides of the clamping plate 2. The fixing holes 22 are internally threaded holes. During operation, the bolts pass through the inner wall of the arc-shaped end of the limiting plate 1. The adhesive is applied by manually pressing the inner arc surface of the limiting plate 1 against the grafting point with one hand, while pulling the pull hole 13 outward with the other hand. This further presses the inner arc surface of the limiting plate 1 against the grafting point. After a certain period of time, the pull hole 13 is released, and the clamping plate 2 is moved towards the inner arc surface of the limiting plate 1, causing the limiting frame 21 to engage with both sides of the limiting plate 1 until the fixing hole 22 moves to the positioning hole 11. At this point, the limiting strip 23 abuts and limits the other side of the grafting point. By screwing the fixing bolt 13 into the fixing hole 22 and the positioning hole 11, the installation and connection of the limiting plate 1 and the clamping plate 2 are completed, allowing them to work together to fix the grafting position.

[0024] Preferably, in one embodiment, such as Figure 3 As shown, the inner ring of the pull hole 13 is smooth and polished, and an annular rubber pad 14 is installed inside the pull hole 13 to improve the comfort of manual operation.

[0025] Preferably, in one embodiment, such as Figure 3 As shown, multiple positioning holes 11 are spaced apart, and the spacing between adjacent positioning holes 11 is set according to the diameter range of the tree, so that the whole device can be adapted to grafting operations of trees of different sizes.

[0026] Preferably, in one embodiment, such as Figure 3 As shown, the top surface of the arc-shaped end of the limiting plate 1 is provided with an arc-shaped eave 15. The top surface of the arc-shaped eave 15 is an arc-shaped structure that expands outward. The upper dimension of the arc-shaped eave 15 is larger than the lower dimension. During operation, the arc-shaped eave 15 allows the soft adhesive to be bonded to the lower part of the inner arc surface of the limiting plate 1, ensuring that the limiting plate 1 still has adhesive properties. After the limiting plate 1 and the clamping plate 2 are installed, sterile cotton is inserted into the arc-shaped eave 15. The sterile cotton is made of medical cotton and disinfectant, which can improve the protection of the grafting position, isolate external rainwater and impurities as much as possible, improve the survival rate of grafting, and the arc-shaped eave 15 allows for easy manual replacement of the sterile cotton, further improving the protection of the grafting position.

[0027] Preferably, in one embodiment, such as Figure 4As shown, a connecting rod 24 is installed on the right side of the clamping plate 2. An installation tube 25 is installed at the extended end of the connecting rod 24. The installation tube 25 has an internally threaded structure. An auxiliary rod 3 is installed inside the installation tube 25. The upper part of the auxiliary rod 3 is a threaded section, and the bottom of the auxiliary rod 3 is a tapered rod 31. During operation, after the limiting plate 1 and the clamping plate 2 are installed, the auxiliary rod 3 is inserted into the installation tube 25 from top to bottom. When the threaded section of the auxiliary rod 3 contacts the installation tube 25, the auxiliary rod 3 is turned to make the auxiliary rod 3 and the installation tube 25 threadedly engage and connect. At the same time, the tapered rod 31 is driven into the ground. The auxiliary rod 3 can provide auxiliary support for the limiting plate 1 and the clamping plate 2, thereby improving the functionality of the overall equipment. When grafting small-diameter trees, the auxiliary rod 3 is not needed. When grafting medium and large-diameter trees, the auxiliary rod 3 is used to make the overall equipment more stable.

[0028] Working principle of this utility model:

[0029] During operation, soft adhesive is adhered to the inner wall of the arc-shaped end of the limiting plate 1. The inner arc surface of the limiting plate 1 is pressed against the grafting point by one hand, while the other hand pulls the pull hole 13 outward to further press the soft adhesive on the inner arc surface of the limiting plate 1 against the grafting point. After a certain period of time, the pull hole 13 is released, and the clamping plate 2 is moved towards the inner arc surface of the limiting plate 1, so that the limiting frame 21 is engaged with both sides of the limiting plate 1 until the fixing hole 22 is moved to the positioning hole 11. At this time, the limiting strip 23 abuts and limits the other side of the grafting point. By screwing the fixing bolt 13 into the fixing hole 22 and the positioning hole 11, the installation and connection of the limiting plate 1 and the clamping plate 2 are completed, so that the two work together to fix the grafting position.

[0030] The above embodiments are merely one of the preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any modifications or refinements made to the main design concept and spirit of this utility model that are not of substantial significance, but solve the same technical problem as this utility model, should be included within the scope of protection of this utility model.
