Abstract
Description
Technical Field
[0001] This utility model relates to the field of grafting tool technology, specifically a grafting reinforcement device. Background Technology
[0002] Grafting is a form of vegetative reproduction in which a branch or bud of one plant (called the "scion") is attached to the stem or root of another plant (called the "rootstock"), allowing the cambium layers of both plants to come into close contact. Because the cambium cells have the ability to divide, they can divide outward to produce phloem containing sieve tubes, and divide inward to produce xylem containing vessels. In this way, the vascular tissues of the two plants are united into a whole, ensuring that water and inorganic salts are transported upward from the roots, and that organic nutrients produced by photosynthesis are transported downward to the roots. The grafted plant can then survive and perform normal physiological functions.
[0003] Patent CN221829532U discloses a protective clip for fruit tree grafting joints, comprising two sets of reinforced outer covers that can be joined and assembled on the outside of the grafted tree. An elastic pad is fixedly installed on the inner wall of the reinforced outer cover, and the inner wall of the elastic pad has a moldable fitting pad that can be stored inside. The elastic pad itself has deformation elasticity, and the molding paste inside the molding fitting pad can be fitted to the grafted tree to form a suitable clamping surface for fixation. This device mainly relies on the internal elastic pad and molding fitting pad to adapt to branches of different diameters. If the branch diameter is small, the deformation of the elastic pad and molding fitting pad is small, resulting in a weaker clamping force and poorer fixation. If the branch is thick, the fixed diameter of the reinforced outer cover may lead to a mismatch between the outer cover and the branch. Therefore, its versatility and clamping stability need improvement. Utility Model Content
[0004] This invention addresses the aforementioned shortcomings of existing technologies by providing a grafting reinforcement device. By tightening the pressure band with a pull ring, the binding force at the grafting point can be precisely controlled, avoiding excessive looseness or tightness, thereby enhancing the stability and fixation effect of the grafting site and ensuring a high grafting success rate.

[0010] 2. The high-elasticity protective pad inside the positioning groove of this utility model provides stable positioning while greatly buffering the pressure of the pressing block on the bark of the branch, minimizing hard squeezing, abrasion or friction damage caused by the pressing block, and protecting the activity of the cambium and phloem; the flexible design of the pressing band helps to distribute the binding force more evenly around the grafting site, reducing the damage caused by local stress concentration to fragile callus tissue or new scion. 3.

Detailed Implementation 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.
[0012] like Figure 1 , Figure 2 As shown, a grafting reinforcement device includes a pressure block 1, made of rigid plastic (such as nylon, ABS) or lightweight metal (such as aluminum alloy); a tightening member 2 is connected to one side of the pressure block 1, such as... Figure 3 As shown, the tightening component 2 includes a pressure band 204, with pull straps 201 connected to its upper and lower ends. The pull straps 201 are made of flexible, wear-resistant, and strong strip-shaped soft plastic material. One end of the pull straps 201 is connected to the pressure block 1. The pressure block 1 has a locking hole 101 that mates with the pull straps 201. The two locking holes 101 are connected by a clearance hole 102. The pull straps 201 mate with the clearance hole 102. The side wall of the pull straps 201 has a slot. The pressure block 1 has a locking piece 106 that mates with the slot. The side wall of the pressure block 1 has a slider 105 that slides the locking piece 106. By pushing the slider 105, the locking piece 106 can be disengaged from the slot 202, thus unlocking the device. The side wall of the pressing block 1 is provided with a concave "V"-shaped positioning groove 104, and a protective pad 103 is provided in the positioning groove 104. The positioning groove 104 can be used to position the pressing block 1 in conjunction with the branch, adapting to grafted branches of different diameters, achieving stable positioning, and preventing the pressing block 1 from sliding. The protective pad 103 is made of foamed rubber or sponge silicone instead of ordinary rubber, providing better cushioning performance, further reducing the risk of crushing the bark of the branch, and also has an anti-slip function.
[0013] A reinforcing rope 203 is attached to the outside of the pressure band 204. The two ends of the reinforcing rope 203 are connected to the pull band 201 through the connecting rod 205. The reinforcing rope 203 is used to tighten and fix the outside of the pressure band 204. The movable end of the pull belt 201 is connected to a pull ring 206. The thickness of the pull ring 206 is less than that of the pull belt 201. The pull ring 206 can pass through the relief hole 102. With the help of the pull ring 206, the pressure belt 204 can be tightened easily, making it convenient to use. The pull strap 201 is made of nylon mesh, cloth (the material of the cloth is not limited) or plastic sheeting, and is used to fix the grafting point or grafting wrapping tape.
[0014] like Figure 4 As shown, the pressure block 1 has a guide hole 109 inside, and one end of the locking piece 106 is connected to a push block 108 that cooperates with the guide hole 109. A spring 110 is connected between the push block 108 and the inner wall of the guide hole 109. The side wall of the pressure block 1 has a sliding hole 107 that communicates with the guide hole 109. The bottom of the slider 105 passes through the sliding hole 107 and is connected to the push block 108.
[0015] like Figure 5 As shown, the installation procedure is as follows: First, align the positioning groove 104 of the pressing block 1 with the branch near the grafting point and press it tightly so that the protective pad 103 contacts the branch to prevent slippage and damage.
[0016] Wrap the pressure band 204 around the grafting point (or the existing grafting wrapping band) so that the grafting point is located inside the pressure band 204.
[0017] The movable ends of the two pull straps 201 are respectively passed through the two locking holes 101 on the pressure block 1.
[0018] When further tightening is required, the user can pull the pull ring 206 and the pull strap 201 to tighten.
[0019] When the pull strap 201 is tightened, the slider 105 is released. Under the action of the spring 110, the locking piece 106 will automatically spring into the slot 202 on the pull strap 201, locking the position of the pull strap 201, thereby fixing the pressure applied by the pressure belt 204 at the grafting point.
[0020] When the grafting and growth process is complete and the device needs to be removed, the user simply pushes the corresponding slider 105 on the side wall of the pressure block 1. The slider 105 drives the push block 108 to overcome the force of the spring 110, pushing the locking piece 106 out of the slot and disengaging it. At this time, the pull strap 201 is in a free state and can be easily pulled out.
[0021] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
