Description

Technical Field

[0001] This utility model relates to the field of camellia bonding technology, and in particular to a Yunnan camellia bonding clamp. Background Technology

[0002] Camellia yunnanensis, a rare and precious flower unique to China, originated in the humid valleys of western and central Yunnan at an altitude of 1900-2600 meters. It is a national second-class protected plant. Its flowers are diverse, encompassing more than a hundred cultivated varieties such as pine nut scale, chrysanthemum petal, and purple robe. It is famous for its magnificent sea of ​​flowers with "ten thousand buds on one tree", and has both ornamental and ecological conservation value. In existing technologies, approach grafting of Camellia yunnanensis mainly relies on manual operation. After aligning the cambium layers of the rootstock and scion, they are fixed with plastic grafting clips. However, due to the prominent internode bulges, thin and brittle bark, and large sap flow of Camellia yunnanensis branches, existing plastic grafting clips often have the following defects when in use: First, uneven pressure distribution—the bulging areas of the internodes are crushed first, while the concave areas of the internodes do not fit together, causing misalignment; second, sap cannot be drained—the accumulated sap forms a water film at the cut, reducing the contact area of ​​the cambium layers; third, insufficient aeration—the callus tissue becomes hypoxic and blackens, with a survival rate of only about 70%. Currently, there is no special approach grafting clip for Camellia yunnanensis that addresses the above physiological characteristics. Therefore, there is an urgent need for a special approach grafting clip for Camellia yunnanensis that can solve the above defects. Utility Model Content

[0003] The purpose of this utility model is to provide a clamp for grafting Yunnan camellia, which can easily fix the raised position of the internode of Yunnan camellia, prevent uneven pressure distribution, facilitate the drainage of sap, increase the air permeability of the clamp, and thus improve the survival rate of Yunnan camellia after grafting.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A Yunnan camellia-shaped clamp includes a first semi-ring body, a fixed shell at one end of the first semi-ring body, a fixed opening at the end of the fixed shell away from the first semi-ring body, a second semi-ring body rotatably connected to the free end of the first semi-ring body and slidably connected to the fixed opening, a plurality of fixed slots equally spaced at the free end of the second semi-ring body, a limit rod rotatably connected to the interior of the fixed shell near the first semi-ring body, a plurality of fixed blocks equally spaced at the free end of the limit rod that cooperate with the fixed slots, each fixed slot having a first inclined surface, and each fixed block having a second inclined surface slidably connected to each second inclined surface; The fixed shell has a slidable limiting plate connected to the interior of the fixed shell away from the fixed rod. A spring is provided between the limiting plate and the limiting rod. A threaded rod is provided at the end of the fixed plate away from the spring and is slidably connected to the fixed shell. An adjusting knob is rotatably connected to the threaded rod on the outside of the fixed shell. Silicone buffer pads are detachably provided on the inner sides of the first half-ring and the second half-ring. Multiple grooves are provided on the inner side of each silicone buffer pad. A V-shaped tool setting groove is provided on the inner side of the second half-ring. An overflow hole is provided on the inner side of the tool setting groove. Elastic pressure plates are provided at both the front and rear ends of the inner side of the tool setting groove. Ventilation windows are provided on the outer sides of the first half-ring and the second half-ring. A biodegradable film is provided inside each ventilation window.

[0005] By adopting the above technical solution, during use, after grafting the Camellia yunnanensis scion onto the rootstock, the second half-ring is rotated relative to the first half-ring, and the second half-ring is inserted into the fixing shell through the fixing port. The first inclined surface slides relative to the second inclined surface, and then, under the elastic force of the spring plate, the limiting rod is pushed, causing the fixing block to lock into the fixing port, allowing the first and second half-rings to clamp and fix the scion. The grooves on the silicone buffer pad facilitate wrapping and fixing the internode protrusions on the Camellia yunnanensis branches, preventing misalignment. During the fixing process, the cutting groove is aligned with the incision, and the first and second half-rings are... After the semi-ring is clamped and fixed, the scion and rootstock cut surfaces are gently squeezed again by the elastic pressure plate, so that the cambium layers fit tightly together. The sap is discharged through the overflow port. By rotating the adjustment knob, the adjustment knob rotates relative to the threaded rod, which drives the limiting plate to slide relative to the fixed shell, changing the compression of the spring piece, thereby changing the elastic force generated by the spring piece, changing the force of the spring piece pushing the limiting rod, and thus changing the pre-tightening force during fixing. After clamping and fixing, the ventilation window increases the air permeability. The biodegradable film inside the ventilation window can prevent rainwater from entering and also maintain the humidity of the callus environment, thereby improving the survival rate of Camellia yunnanensis grafting.

[0006] A further feature of this invention is that the fixed opening at the end of the fixed shell away from the first semi-ring body is provided with a limiting strip for restricting the rotation of the limiting rod.

[0007] A further feature of this invention is that: the inner sides of the first semi-ring and the second semi-ring are provided with a plurality of fixing holes arranged at equal intervals, and the outer sides of each silicone buffer pad are provided with a plurality of dovetail wedges that correspond one-to-one with the fixing holes and cooperate with each other.

[0008] A further feature of this invention is that the free end of each elastic pressure plate is 0.2-0.3 mm higher than the corresponding silicone buffer pad.

[0009] The present invention is further configured such that: the first semi-ring and the second semi-ring are both made of glass fiber reinforced nylon, the wall thickness of the first semi-ring and the second semi-ring is 1.2 mm, and the overall weight is less than or equal to 6 g.

[0010] A further feature of this invention is that the biodegradable film is made of polylactic acid, and the thickness of each biodegradable film is 0.1 mm.

[0011] In summary, this utility model has the following beneficial effects: Firstly, it facilitates the clamping and fixing of the internode ridges on Yunnan camellia. Through the silicone buffer pad and groove, it is easy to make the silicone buffer pad fit the internode ridge during fixing, thereby ensuring that the pressure around the internode ridge is uniform and preventing crushing. Secondly, the groove and overflow hole facilitate the timely discharge of sap, preventing the formation of a water film and reducing the contact area of ​​the cambium. The elastic pressing plate allows for a slight re-pressure between the scion and the rootstock cut surface while clamping, thereby improving the adhesion of the cambium by 30%. Thirdly, the ventilation window improves air permeability, and the biodegradable film prevents rainwater from entering while maintaining the humidity of the healing environment at 80%±5%, thus improving the healing speed. Fourth, by rotating the adjustment knob, the screw rod moves relative to the adjustment knob, and the threaded rod moves the limit plate, changing the degree of bending of the elastic piece pushed by the limit plate, thus adjusting the elastic force generated by the elastic piece, thereby changing the preload of fixing the second half-ring.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; or they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0018] Example, refer to Figure 1-5 A Yunnan camellia-shaped clamp includes a first semi-ring 1, with a fixed shell 2 at one end of the first semi-ring 1. A fixed opening 3 is provided on the lower side of the left end of the fixed shell 2. A second semi-ring 4 is rotatably connected to the end of the first semi-ring 1 away from the fixed shell 2 and slidably connected to the fixed opening 3. The first semi-ring 1 and the second semi-ring 4 are both made of glass fiber reinforced nylon 66. The wall thickness of the first semi-ring 1 and the second semi-ring 4 is 1.2mm, and the overall weight is less than or equal to 6g.

[0019] A silicone buffer pad 13 is detachably installed on the inner side of both the first semi-ring 1 and the second semi-ring 4. Each silicone buffer pad 13 has several equally spaced grooves 14 on its inner side. The pitch of the grooves 14 is 12-16mm, and the groove depth is 0.4-0.6mm, which can easily accommodate the internode protrusions of Camellia yunnanensis branches. Four equally spaced fixing holes 16 are provided on the inner side of both the first semi-ring 1 and the second semi-ring 4. Four dovetail wedges 15 are equally spaced on the outer side of each silicone buffer pad 13, which correspond one-to-one with the fixing holes 16 and cooperate with each other. The hardness of the silicone buffer pad 13 is Shore A 25-35, which can facilitate the disassembly and replacement of the silicone buffer pad 13.

[0020] The outer side of the second semi-ring 4, away from the first semi-ring 1, has several equally spaced fixing slots 5. Each fixing slot 5 is provided with a first inclined surface 501 that is inclined from bottom to top. A limiting rod 6 is rotatably connected between the right sides of the front and rear ends inside the fixed shell 2. Two fixing blocks 7 that cooperate with the fixing slots 5 are equally spaced on the left side of the lower end of the limiting rod 6. Each fixing block 7 is provided with a second inclined surface 701 that is inclined from top to bottom and slidably connected to each first inclined surface 501. A limiting plate 10 is slidably connected to the inside of the fixed shell 2 above the limiting rod 6. A threaded rod 11 that is slidably connected to the fixed shell 2 is vertically provided in the middle of the upper end of the limiting plate 10. An adjusting knob 12 that is threadedly connected to the threaded rod 11 is rotatably connected in the middle of the upper end of the fixed shell 2, which can facilitate the adjustment of the preload between the fixing blocks 7 and the fixing slots 5, and the adjustment range is 5-15N.

[0021] A V-shaped groove 17 is provided in the middle of the inner side of the second semi-ring 4. An overflow hole 18 is provided on the inner side of the groove 17. An elastic pressure plate 19 is provided at both the front and rear ends of the inner side of the groove 17. The end of each elastic pressure plate 19 away from the second semi-ring 4 is 130.2-0.3mm higher than the corresponding silicone buffer pad, which makes it easy to gently squeeze the scion and rootstock cut plane again while clamping, so that the cambium layer is tightly attached. Four equally spaced ventilation windows 20 are provided on the outer side of the first semi-ring 1 and the outer side of the second semi-ring 4. A biodegradable film 21 is provided on the inner side of each ventilation window 20. Each biodegradable film 21 is made of polylactic acid and has a thickness of 0.1mm. It can prevent rainwater from entering and ensure that the humidity of the callus environment is 80%±5%.

[0022] Usage: When using, after grafting the Camellia yunnanensis scion onto the rootstock, pull the second half-ring 4 to rotate relative to the first half-ring 1, inserting the second half-ring 4 into the fixing shell 2 through the fixing port 3. Push the first inclined surface 501 to slide relative to the second inclined surface 701. Then, under the elastic force of the spring piece 9, push the limiting rod 6, causing the fixing block 7 to lock into the fixing port 5, allowing the first half-ring 1 and the second half-ring 4 to clamp and fix the scion. The groove 14 on the silicone buffer pad 13 facilitates wrapping and securing the internode ridges on the Camellia yunnanensis branches, preventing... To prevent misalignment, during the fixing process, the groove 17 is aligned with the cut. After the first half-ring 1 and the second half-ring 4 are clamped and fixed, the scion and the rootstock cut plane are slightly squeezed again by the elastic pressure plate 19, so that the cambium layers are tightly attached and the sap is discharged through the overflow port. The limiting strip 8 can prevent the limiting rod 6 from rotating excessively under the elastic force of the spring plate 9, and prevent the second half-ring 4 from being unable to be inserted into the fixing shell 2 for fixing. The silicone buffer pad 13 is fixed by inserting the dovetail wedge 15 into the fixing hole 16, which makes it easy to replace the silicone buffer pad 13.

[0023] By rotating the adjusting knob 12, the adjusting knob 12 rotates relative to the threaded rod 11, causing the limiting plate 10 to slide relative to the fixed shell 2, changing the compression of the spring 9, thereby changing the elastic force generated by the spring 9, changing the force of the spring 9 pushing the limiting rod 6, and thus changing the pre-tightening force during fixing. After clamping and fixing, the ventilation window 20 increases the air permeability. The biodegradable film 21 inside the ventilation window 20 can prevent rainwater from entering and can also ensure the humidity of the callus environment, thereby improving the survival rate of Camellia yunnanensis grafting.
