Description

Technical Field

[0001] This utility model relates to the field of seedling grafting technology, and in particular to a fixation and wound healing clip for seedling grafting. Background Technology

[0002] Grafting is an important technique in agricultural production and horticulture. Its success hinges on the close contact between the cambium layers of the scion and rootstock, and the smooth formation and connection of callus tissue at the grafting wound. Currently, sealing tape is commonly used to fix the grafting site. While sealing tape provides some moisture retention, its fixation strength is often insufficient, and it cannot provide the plant growth regulators needed for callus growth. Utility Model Content

[0003] The main purpose of this invention is to provide a fixation and wound healing clip for seedling grafting, so as to solve the problems raised in related technologies.

[0004] To achieve the above objectives, according to one aspect of the present invention, a fixing and wound healing clip for seedling grafting is provided, comprising two symmetrically arranged clamping parts and a wound healing part, wherein the two clamping parts are rotatably arranged for clamping the seedling, and the wound healing part is inserted into the clamping parts for wrapping the wound of the seedling; the wound healing part includes a moisture-absorbing block, the moisture-absorbing block being soaked in plant nutrients.

[0005] Furthermore, the clamping part includes an arc-shaped clamp body, and a handle is fixedly provided at the outer tail of the arc-shaped clamp body. Pressing the two handles can open the two arc-shaped clamp bodies.

[0006] Furthermore, a base is fixedly provided at the bottom of the inner side of the arc-shaped clamp, and a number of limiting posts are fixedly provided on the upper surface of the base. The base and the limiting posts are used to install the growth-promoting part.

[0007] Furthermore, several lugs are fixedly provided on the side of the tail of the arc-shaped clamp, and the lugs on the two arc-shaped clamps are arranged alternately.

[0008] Furthermore, a rotating shaft is provided through several of the lugs, and the rotating shaft is rotatably connected to the lugs. A return torsion spring is provided on the outer ring of the rotating shaft.

[0009] Furthermore, the moisture-absorbing block has several through guide holes along the vertical direction.

[0010] Furthermore, the outer side of the moisture-absorbing block is the outer edge of the moisture-absorbing block, the inner side is the inner edge of the moisture-absorbing block, and the tail is a protrusion, the protrusion being made of the same material as the moisture-absorbing block.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. The growth-promoting component can be easily installed inside the clamping part via the base and limiting posts. This plug-in structure ensures that the growth-promoting component will not easily shift or fall off during repeated opening and closing of the clamp or during seedling growth, guaranteeing the continuity and stability of its healing-promoting effect. At the same time, as an independent component, the growth-promoting component can be pre-soaked with different growth regulators according to the seedling type and grafting requirements, improving the flexibility of use.

[0012] 2. The growth-promoting section is made of flexible, moisture-absorbing material, which can tightly conform to the grafting wound under the pressure of the clamping section. Its inner edge protrudes from the abutment, preventing direct contact and damage to the seedling from the hard abutment. In particular, the protrusion at the tail of the growth-promoting section can align with each other when the two clamping sections are closed, effectively sealing the end of the grafting wound and forming a complete ring-shaped wrap around the wound. This structure prevents the wound from being exposed, promotes callus formation, and increases the grafting survival rate. Attached Figure Description

[0015] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0016] This embodiment provides a fixation and callus-promoting clip for seedling grafting, such as... Figure 2 As shown, it mainly consists of two symmetrically arranged clamping parts 1 and two separable growth-promoting parts 2. The two clamping parts 1 are opened and closed by a rotating connection, and are used to jointly clamp the grafting site of the seedling. The growth-promoting parts 2 are inserted and installed inside the clamping parts 1. When the clamping parts 1 are closed, the growth-promoting parts 2 can tightly wrap around the grafting wound of the seedling, such as... Figure 1 As shown.

[0017] Specifically, such as Figure 3 As shown, the clamping part 1 includes an arc-shaped clamping body 11. This arc-shaped clamping body 11 is preferably semi-circular, so that when the two clamping parts 1 are closed, they form a complete ring, evenly gripping the seedling. At the outer end of the arc-shaped clamping body 11, an outwardly extending handle 12 is fixedly provided. By pressing the two handles 12 towards the center, the user can use leverage to open the front ends of the two arc-shaped clamping bodies 11, as shown. Figure 2 As shown, this allows the seedlings to be placed in the container; after releasing the handle 12, the arc-shaped clamp 11 closes and clamps under the action of the reset torsion spring.

[0018] To install the growth promoter 2, a base 13 is fixedly installed at the bottom of the inner side (i.e., the side closest to the seedling) of the arc-shaped clamp 11. Several upwardly protruding limiting posts 14 are fixedly installed on the upper surface of the base 13. The base 13 and the limiting posts 14 together form an installation platform for supporting and fixing the growth promoter 2.

[0019] The rotatable connection between the two clamping parts 1 is achieved through the following structure: Several lugs 15 are fixedly provided on the side of the tail of the arc-shaped clamping body 11. The lugs 15 on the two arc-shaped clamping bodies 11 are arranged alternately. A rotating shaft 16 passes through all these alternate lugs 15 in sequence and forms a rotatable connection with each lug 15. A return torsion spring (not shown in the figure) is also sleeved on the outer ring of the rotating shaft 16. The two ends of the return torsion spring act on the two handles 12 respectively, providing them with a continuous closing torque to ensure that the clamping part 1 remains closed when not manually operated.

[0020] like Figure 4 As shown, the growth-promoting part 2 includes a strip-shaped absorbent block 21. The absorbent block 21 is made of a material with good absorbency and flexibility, such as cellulose sponge, non-woven fabric, or superabsorbent resin gel. This material can fully impregnate the plant growth regulator solution and deform with the shape of the seedling when clamped by the arc-shaped clamp 11, ensuring close contact with the wound surface. Several through guide holes 22 are formed along the vertical direction of the absorbent block 21. The shape and size of these guide holes 22 are adapted to the limiting posts 14 on the clamping part 1.

[0021] The moisture-absorbing block 21 has a specific outline: its outer side is the outer edge 23 of the moisture-absorbing block, which faces the arc-shaped clamp 11 after installation; its inner side is the inner edge 24 of the moisture-absorbing block, which faces the seedlings after installation; and its tail is an integrally formed protrusion 25, which is made of the same material as the main body of the moisture-absorbing block 21.

[0022] When the arc-shaped clamp 11 is closed, the front ends of the moisture-absorbing blocks 21 come into contact with each other, preventing the grafting wound from being exposed at the front end of the moisture-absorbing blocks 21 and thus preventing it from contacting the growth regulator.

[0023] When assembling this growth-promoting clip, first install the growth-promoting part 2 onto the clamping part 1. During installation, align the protrusion 25 at the tail of the growth-promoting part 2 with the handle 12, then align the guide holes 22 on the moisture-absorbing block 21 and fit them onto the corresponding limiting posts 14, so that the bottom of the moisture-absorbing block 21 rests stably against the surface of the base 13. Here, the thickness of the moisture-absorbing block 21 is designed to be greater than the width of the base 13. Therefore, when the growth-promoting part 2 is installed in place, its outer edge 23 will be embedded in the gap between the arc-shaped clamping body 11 and the top of the limiting post 14. This structure can effectively prevent the growth-promoting part 2 from accidentally falling off the clamping part 1 during use. At the same time, the inner edge 24 of the moisture-absorbing block will protrude from the inner edge of the base 13. In this way, when clamping the seedling, the soft inner edge 24 of the moisture-absorbing block contacts and wraps around the seedling, avoiding possible pinching damage to the seedling bark caused by the hard edge of the base 13.

[0024] When in use, the growth-promoting clip is held on the grafted seedling, and the two clamping parts 1 are completely closed. At this time, the protrusions 25 at the tails of the two growth-promoting parts 2 will contact each other or fit tightly together. This design ensures that the end of the grafting wound is also completely wrapped by the growth-promoting parts 2, leaving no exposed gaps and providing all-round protection for the wound. Finally, the two arc-shaped clamps 11 form a sturdy fixing ring, while the two moisture-absorbing blocks 21 and their protrusions 25 together form a continuous, soft wrapping ring filled with growth regulator, creating excellent conditions for the healing of the grafting wound. Moreover, the growth-promoting clip is reusable; it can be reused simply by adding plant growth regulator solution directly to the moisture-absorbing block 21 after it is used up.

[0025] 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 way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
