Abstract
Description
Technical Field
[0001] This utility model relates to the field of tobacco cultivation technology, and more specifically, to an adjustable tobacco seedling grafting clip. Background Technology
[0002] Grafting is an asexual reproduction method that involves grafting a branch or bud from one plant onto another, resulting in a new plant. This technique allows for root replacement of grafted varieties, enhancing plant growth and resistance to adverse conditions, and producing high-quality, high-yield plants in a short period. It is of great significance in controlling pests and diseases, preserving germplasm resources, improving superior varieties, cultivating virus-free seedlings, and overcoming incompatibility between plants. Currently, this technology has been applied in the tobacco industry.
[0003] The quality of graft union healing directly affects the survival rate, growth, and quality of grafted plants. Currently used grafting clips, due to their poor air permeability and excessively tight or loose fastening, severely impair the healing of grafting wounds, leading to phenomena such as scion and rootstock detachment, unhealed or even rotten wounds, and low survival rates of grafted plants.
[0004] Therefore, there is an urgent need for an adjustable tobacco seedling grafting clip. Utility Model Content
[0005] The purpose of this invention is to provide an adjustable tobacco seedling grafting clip to solve the problems in the prior art. It can adjust the clamping force of the left and right arc-shaped clips on the grafting interface, avoiding excessive clamping force that could damage the tobacco seedling, or insufficient clamping force that could cause the scion to fall off the rootstock.
[0006] This utility model provides an adjustable tobacco seedling grafting clip, comprising: a left arc-shaped clip and a right arc-shaped clip arranged opposite each other. The interior of the left arc-shaped clip and the right arc-shaped clip are both hollow structures, and multiple first springs are spaced apart inside the left arc-shaped clip and the right arc-shaped clip. The left arc-shaped clip and the right arc-shaped clip are arranged in a circle with a cavity in the middle. The two opposite ends of the left arc-shaped clip and the right arc-shaped clip are respectively an outer end and an inner end. A left holding plate and a right holding plate are respectively provided on the outer side of the inner end of the left arc-shaped clip and the right arc-shaped clip.
[0007] In the adjustable tobacco seedling grafting clip described above, preferably, a second spring is provided between the left holding plate and the right holding plate.
[0008] In the adjustable tobacco seedling grafting clip described above, preferably, the second spring is circular in shape.
[0009] In the adjustable tobacco seedling grafting clip described above, preferably, the outer ends of the left arc-shaped clip and the right arc-shaped clip are respectively provided with a small plate and a third spring mounted on the small plate, wherein the small plate is located inside the outer end and the third spring is located outside the outer end.
[0010] In the adjustable tobacco seedling grafting clip described above, preferably, the inner wall of the cavity is provided with multiple small holes.
[0011] In the adjustable tobacco seedling grafting clip described above, preferably, the small holes on the inner wall of the cavity corresponding to the left arc-shaped clip and the right arc-shaped clip are evenly distributed in a matrix.
[0012] In the adjustable tobacco seedling grafting clip described above, preferably, the small hole is circular in shape and the diameter of the small hole is 3mm-7mm.
[0013] In the adjustable tobacco seedling grafting clip described above, preferably, the angle between the left holding plate and the left arc-shaped clip is an acute angle, and the angle between the right holding plate and the right arc-shaped clip is an acute angle, and the angle between the right holding plate and the right arc-shaped clip is an acute angle with the left arc-shaped clip.
[0014] In the adjustable tobacco seedling grafting clip described above, preferably, the angle between the left arc-shaped clip and the right arc-shaped clip is 30°-60°.
[0015] In the adjustable tobacco seedling grafting clip described above, preferably, the number of the first springs inside the left arc-shaped clip and the right arc-shaped clip is 2-5, and they are distributed radially.
[0016] This invention provides an adjustable tobacco seedling grafting clip. The elasticity of the first spring allows for adjustment of the clamping force of the left and right arc-shaped clips on the graft union, preventing excessive clamping force from damaging the seedling or insufficient clamping force from causing the scion to detach from the rootstock. The small plate and third spring ensure both buffer space for the first spring and a closed outer end, guaranteeing both air permeability and moisture retention. Small holes ensure good air permeability at the graft union and maintain appropriate tightness. The design is simple and lightweight, possessing not only the basic functions of a tobacco seedling grafting clip but also effectively improving the tightness of the clip, increasing air permeability, enhancing grafting wound healing ability, and improving plant survival rate.

[0026] like Figure 1 and Figure 2 As shown, the adjustable tobacco seedling grafting clip provided in this embodiment includes: a left arc-shaped clip 3 and a right arc-shaped clip 4 arranged opposite to each other. The interior of the left arc-shaped clip 3 and the right arc-shaped clip 4 are both hollow structures, and a plurality of first springs 5 are arranged at intervals inside the left arc-shaped clip 3 and the right arc-shaped clip 4. The left arc-shaped clip 3 and the right arc-shaped clip 4 are arranged in a circle with a cavity 6 in the middle. The two opposite ends of the left arc-shaped clip 3 and the right arc-shaped clip 4 are an outer end 1 and an inner end 2, respectively. A left holding plate 7 and a right holding plate 9 are respectively arranged on the outer side of the inner end 2 corresponding to the left arc-shaped clip 3 and the right arc-shaped clip 4.
[0027] The number of first springs 5 inside the left arc-shaped clamp 3 and the right arc-shaped clamp 4 is 2-5, for example, 3, and they are distributed radially. It should be noted that this utility model does not specifically limit the number and distribution of the first springs 5.
[0028] Furthermore, the angle between the left holding plate 7 and the left arc-shaped clamp 3 is an acute angle, and the angle between the right holding plate 9 and the right arc-shaped clamp 4 is an acute angle. The angle between the left arc-shaped clamp 3 and the right arc-shaped clamp 4 is 30°-60°, for example, 45°.
[0029] During the work, hold the left holding plate 7 and the right holding plate 9 inwards to open the outer ends 1 of the left arc-shaped clamp 3 and the right arc-shaped clamp 4, and clamp them on the grafting interface of the tobacco seedling. This is suitable for fixing tobacco seedlings of different diameters. The elasticity of the first spring 5 can reduce the clamping force of the left arc-shaped clamp 3 and the right arc-shaped clamp 4 on the grafting interface, so as to avoid damaging the tobacco seedling with too much clamping force or causing the scion and rootstock to fall off if the clamping force is too small.
[0030] Furthermore, a second spring 8 is provided between the left holding plate 7 and the right holding plate 9. The second spring 8 is circular in shape. It should be noted that the shape of the second spring 8, the included angle between the left arc-shaped clamp 3 and the right arc-shaped clamp 4, and the relative position of the second spring 8 between the left holding plate 7 and the right holding plate 9 are not specifically limited in this invention.
[0031] Furthermore, the outer ends 1 corresponding to the left arc-shaped clamp 3 and the right arc-shaped clamp 4 are respectively provided with a small plate 12 and a third spring 11 mounted on the small plate 12, wherein the small plate 12 is located inside the outer end 1, and the third spring 11 is located outside the outer end 1. Through the small plate 12 and the third spring 11, both the buffer space of the first spring 5 and the connection between the outer ends 1 corresponding to the left arc-shaped clamp 3 and the right arc-shaped clamp 4 are closed inwards, ensuring both breathability and moisture retention. In one embodiment of this utility model, the small plate 12 is an iron plate, and the small plate 12 and the third spring 11 corresponding to the left arc-shaped clamp 3 and the right arc-shaped clamp 4 are staggered on the outer ends 1. It should be noted that this utility model does not specifically limit the material of the small plate 12, the fixing method of the third spring 11 on the small plate 12, or the relative position of the small plate 12 and the third spring 11 on the outer ends 1.
[0032] Furthermore, the inner wall of the cavity 6 is provided with multiple small holes 13. These holes 13 allow for air circulation, ensuring good breathability at the grafting interface and maintaining appropriate tightness. When grafting tobacco seedlings, compared to scions of other vegetables and fruit trees, the rootstock and scion of tobacco seedlings are more delicate, requiring the grafting wound to have good breathability and suitable tightness. Specifically, the small holes 13 on the inner wall of the cavity 6 corresponding to the left arc-shaped clip 3 and the right arc-shaped clip 4 are evenly distributed in a matrix. The small holes 13 are circular in shape, and their diameter is 3mm-7mm, for example, 5mm. It should be noted that this invention does not specifically limit the number, distribution, or diameter of the small holes 13.
[0033] The adjustable tobacco seedling grafting clip provided in this embodiment of the invention allows for adjustment of the clamping force of the left and right arc-shaped clips on the grafting interface through the elasticity of the first spring. This prevents excessive clamping force from damaging the tobacco seedling or insufficient clamping force from causing the scion to detach from the rootstock. The small plate and the third spring ensure both the buffer space of the first spring and the inward sealing of the outer end, thus guaranteeing both air permeability and moisture retention. The small holes ensure good air permeability at the grafting interface and maintain the correct tightness. The structure is simple and easy to use. It not only possesses the basic functions of a tobacco seedling grafting clip but also effectively improves the tightness of the clip, increases air permeability, enhances the healing ability of the grafting wound, and improves the survival rate of the plant.
[0034] The embodiments of this disclosure have now been described in detail. To avoid obscuring the concept of this disclosure, some details known in the art have not been described. Those skilled in the art can fully understand how to implement the technical solutions disclosed herein based on the above description.
[0035] While specific embodiments of this disclosure have been described in detail by way of examples, those skilled in the art should understand that the examples are for illustrative purposes only and not intended to limit the scope of this disclosure. Those skilled in the art should understand that modifications can be made to the above embodiments or equivalent substitutions can be made to some technical features without departing from the scope and spirit of this disclosure.
