Abstract
Description
Technical Field
[0001] This utility model relates to the field of agricultural technology, specifically to a clamping and fixing device for grafted seedlings. Background Technology
[0002] Grafting is an important technique in agriculture and horticulture for improving crop varieties, enhancing plant resistance, and promoting growth and development. It is widely used in the cultivation of fruit trees, vegetables, flowers, and other crops. The survival rate of grafted seedlings is closely related to the effectiveness of fixation after grafting. Good fixation ensures close contact between the scion and rootstock, promotes cambium healing, and reduces problems such as water loss and pathogen infection caused by loosening.
[0003] During the growth of grafted seedlings, both the scion and rootstock gradually thicken. However, most existing fixing devices lack dynamic adjustment capabilities, easily restricting plant growth and requiring regular manual replacement of the fixing components, further increasing maintenance costs and operational complexity. Therefore, developing a convenient, versatile, gentle, and adjustable grafting seedling clamping and fixing device is crucial for addressing the pain points of existing technologies and improving grafting efficiency and survival rate. To this end, we propose a clamping and fixing device for grafted seedlings to solve the aforementioned problems. Utility Model Content
[0004] This invention provides a clamping and fixing device for grafted seedlings, solving the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a clamping and fixing device for grafted seedlings, including a fixing buckle, wherein two sets of fixing buckles are provided, and an adjusting sleeve is provided on the right side of the two sets of fixing buckles. An adjusting post is inserted inside the adjusting sleeve, and an adjusting band and a limiting post are provided on the left side of each fixing buckle.
[0006] Preferably, the fixing buckle consists of two sets of semi-circular frame plates, and the two sets of frame plates are distributed opposite each other to facilitate fixing.
[0007] Preferably, the right sides of the frame plates of the two sets of fixing buckles are hinged together, and the hinge is connected to the left side of the adjusting sleeve, so that the fixing buckles can be adjusted.
[0008] Preferably, the front and rear ends of the fixing buckle are fixedly connected to sponge bodies, and the two sets of sponge bodies are arranged in an arc shape with their close proximity to each other.
[0009] Preferably, the adjusting band is made of an elastic material, and the adjusting band is evenly provided with insertion holes that cooperate with the limiting post, so that the adjusting band can be locked onto the limiting post.
[0010] Preferably, a limiting bolt is inserted into the front surface of the adjusting sleeve, and limiting holes that cooperate with the limiting bolt are evenly opened on the adjusting column, so that it can be fixed by the limiting bolt.
[0011] This utility model provides a clamping and fixing device for grafted seedlings, which has the following beneficial effects:
[0012] The fixing buckle consists of two sets of opposing semi-circular frame plates, which, together with the arc-shaped sponge body fixedly connected at both the front and rear ends, can not only achieve a wrap-around clamping of the grafted seedling to ensure a close fit between the scion and the rootstock, but also buffer the clamping pressure through the flexible contact of the sponge body, avoiding damage to the plant epidermis caused by the hard structure. The arc-shaped sponge body can also adapt to the round contour of the plant, increase the contact area, reduce local pressure, reduce the risk of bacterial infection, and at the same time play a certain role in moisturizing and promoting healing.
[0013] The elastic adjustment band on the left side of the fixing buckle works with the limiting post. By using the evenly spaced holes on the adjustment band to engage with the limiting post, the opening and closing degree of the fixing buckle can be quickly adjusted to accommodate different thicknesses of scions and rootstocks. There is no need to replace the fixing parts of different specifications, which significantly improves the versatility of the device. Compared with traditional manual binding, this structure is simple to operate, saves labor time, and lowers the technical threshold of grafting operations. Attached Figure Description

[0020] 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.
[0021] Please see Figure 1-4 This utility model provides a technical solution: a clamping and fixing device for grafted seedlings, including a fixing buckle 1, two sets of fixing buckles 1, an adjusting sleeve 2 on the right side of the two sets of fixing buckles 1, an adjusting post 8 inserted inside the adjusting sleeve 2, and an adjusting band 4 and a limiting post 5 on the left side of each fixing buckle 1.
[0022] The fixing buckle 1 consists of two sets of semi-circular frame plates, which are distributed opposite each other. The right sides of the frame plates of the two sets of fixing buckles 1 are hinged together, and the hinge is connected to the left side of the adjusting sleeve 2. Both the front and rear ends of the interior of the fixing buckle 1 are fixedly connected with sponge bodies 3, and the two sets of sponge bodies 3 are arranged in an arc shape with close proximity to each other. The sponge bodies 3 provide protection: the sponge bodies 3 inside the fixing buckle 1 can not only increase friction and prevent slippage, but also buffer the pressure during fixing and prevent the stem from being squeezed and deformed. The arc-shaped structure fits perfectly: the two sets of sponge bodies 3 are arc-shaped and close to each other, which can perfectly fit the round stem, ensuring the stability of fixing and preventing damage to the seedling epidermis and cambium due to excessive local force.
[0023] The adjusting band 4 is made of elastic material and has evenly spaced holes that mate with the limiting posts 5. Lateral adjustment: The adjusting band 4, made of elastic material and with holes, allows for flexible adjustment of the tightness of the fixing buckles 1 by engaging with the limiting posts 5, adapting to seedling stems of different diameters. Longitudinal adjustment: The adjusting post 8 can slide within the adjusting sleeve 2. By engaging the limiting bolt 6 with different limiting holes 7, the distance between the two sets of fixing buckles 1 can be adjusted, adapting to the spacing requirements of different grafting positions.
[0024] The front surface of the adjusting sleeve 2 is fitted with a limiting bolt 6, and the adjusting column 8 is evenly provided with limiting holes 7 that mate with the limiting bolt 6. The hinged fixing buckle 1 has its frame plate hinged on the right side, allowing for easy opening and closing, and enabling quick placement and fixation of seedlings without complex assembly. Mechanical limiting fixation: The adjusting sleeve 2 and adjusting column 8, as well as the adjusting belt 4 and limiting column 5, all employ a "bolt-hole" or "column-hole" mechanical limiting structure, ensuring that the fixing is not easily loosened and can resist displacement caused by wind or minor impacts.
[0025] Working principle: In use, first place the two stems into the semi-circular frames of the two sets of fixing buckles 1 respectively. After closing the frame, the adjusting band 4 on the left side elastically contracts to fit the stem. Then, insert the insertion hole on the adjusting band 4 into the limiting post 5. The mechanical limiting locks the opening and closing degree of the fixing buckle 1, so that the arc-shaped sponge 3 inside the frame tightly wraps the stem, which not only prevents slippage but also buffers pressure. The horizontal tension adjustment principle: The elastic material of the adjusting band 4 allows for a certain range of stretching. With the combination of insertion holes at different positions and limiting posts 5, the clamping force of the fixing buckle 1 on the stem can be precisely adjusted: When the stem is thicker, select the insertion hole at the end of the adjusting band 4 (small stretching); when the stem is thinner, select the insertion hole at the front end (large stretching), so as to ensure the fixing force while avoiding excessive tightness that could damage the seedling. The longitudinal spacing adjustment principle: The adjusting post 8 can slide freely in the adjusting sleeve 2. By changing the relative position of the two, the distance between the two sets of fixing buckles 1 can be adjusted to adapt to the stem spacing required for different grafting methods (such as cleft grafting and split grafting).
[0026] After determining the spacing, insert the limiting bolt 6 into the corresponding limiting hole 7 of the adjusting post 8. Mechanical locking secures the relative position of the adjusting sleeve 2 and the adjusting post 8, ensuring the alignment stability of the grafting site. The overall synergistic fixing principle utilizes the arc-shaped structure of the sponge body 3 to conform to the stem shape, increasing the contact area and dispersing pressure; the elastic adjusting band 4 provides continuous clamping force, working in conjunction with the limiting post 5 to prevent loosening; and the rigid connection between the adjusting sleeve 2 and the adjusting post 8 ensures the relative position stability of the two sets of fixing buckles 1. The synergistic effect of these three elements not only securely fixes the grafted seedling but also provides a certain buffer space for seedling growth, while adapting to the grafting needs of seedlings of different sizes.
