Description

Technical Field

[0001] This utility model relates to the field of agricultural technology, and in particular to a grafting fixing device. Background Technology

[0002] Grafting is a common propagation technique in horticulture. By grafting branches (scions) of superior varieties onto rootstocks, it helps to achieve effects such as variety improvement, earlier fruiting, and enhanced resistance to adverse conditions. During the grafting process, the fixation effect between the scion and rootstock affects the grafting survival rate to a certain extent. If the fixation is not firm enough or the force is uneven, it may lead to separation of the scion and rootstock, poor healing of the graft union, or even damage and necrosis of the branch. Currently, the main fixation methods for branch grafting include the binding method (using plastic tape, hemp rope, etc.) and the simple clamp fixation method. The binding method is relatively cumbersome, often requiring multiple layers of wrapping to ensure a certain fixation strength, and it is difficult to precisely adjust the binding force. Too tight a binding can easily damage the bark of the branch, while too loose a binding may result in an unstable fixation. The simple clamp fixation method is usually a rigid structure of a single size, which can only be adapted to branches of a certain thickness and cannot meet the fixation needs of large branches, small branches, and irregularly shaped branches. In addition, the angle of the clamp is mostly fixed and cannot be flexibly adapted and adjusted according to the grafting angle, which may result in insufficient adhesion at the graft union and thus affect the healing effect. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a grafting and fixing device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A grafting fixing device includes a first clamping plate, screws, a plate body, a second clamping plate, a groove, a ball, a bolt, a nut, a slide rod, a handle, and a rubber pad. Two first clamping plates are arranged vertically and threaded through multiple screws. Each of the multiple screws is rotatably connected to a plate body. Each of the multiple plate bodies is provided with a second clamping plate. Each of the multiple second clamping plates has a groove at one or the other end. Each of the multiple grooves is movably connected to a ball. Each of the multiple balls is fixedly connected to a corresponding plate body.

[0005] Preferably, multiple bolts are movably connected through the two first clamping plates, and each of the multiple bolts is threaded with a nut.

[0006] Preferably, each of the second clamping plates has an arc-shaped groove at one or the other end, and both of the first clamping plates are semi-circular.

[0007] Preferably, one or both ends of the plurality of second clamps are fixedly connected with rubber pads.

[0008] Preferably, each of the screws is fixedly connected to a handle.

[0009] Preferably, each of the plurality of plates is fixedly connected to a sliding rod, and the plurality of sliding rods are slidably connected to the corresponding first clamping plate.

[0010] Preferably, the plurality of spheres and corresponding grooves constitute a universal assembly.

[0011] The beneficial effects of this utility model are as follows: 1. Through the cooperation of the first clamping plate, screws, plate, second clamping plate, groove and ball, after the first clamping plate contacts the thick branch, multiple screws drive the corresponding plate and second clamping plate to move. The second clamping plate can be adjusted in all directions by the movable connection between the ball at the plate and the groove at the second clamping plate. This can not only adapt to the fixing needs of branches of different thicknesses, but also flexibly adjust the fitting posture of the second clamping plate according to the grafting angle, which helps to improve the tightness of the joint. At the same time, the clamping force can be controlled by adjusting the screws, reducing the possibility of damage to the branch bark. To a certain extent, this improves the shortcomings of the existing fixing method and provides better protection for grafting healing and survival rate. 2. Through the cooperation between the set first clamping plate, bolts and nuts, when two first clamping plates are connected with multiple bolts, the distance between the two first clamping plates can be flexibly adjusted by the placement of the nuts at the bolts. This can not only adapt to rootstocks or scions of different thicknesses and specifications, allowing the first clamping plate to form a closer contact with the surface of the branch, but also achieve stable fixing of the distance by locking the nuts, avoiding loosening during use.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Example 1, referring to Figures 1 to 5 A grafting fixing device includes a first clamping plate 1, screws 2, a plate 3, a second clamping plate 4, a groove 5, a ball 6, a bolt 7, a nut 8, a slide rod 9, a handle 10, and a rubber pad 11. The two first clamping plates 1 are arranged vertically with multiple screws 2 threaded through them. This vertical arrangement can adapt to the clamping space of branches of different thicknesses. The threaded connection ensures that the screws 2 move stably during adjustment without deviation, providing a structural basis for subsequently moving the plate 3 and the second clamping plate 4 closer to or away from the branch. All screws 2 are rotatably connected to the plate 3. This rotatable connection design ensures that when the screws 2 rotate, they only drive the plate 3 in a linear reciprocating motion, preventing the plate 3 from rotating with the screws 2. This ensures that the second clamping plate 4 always maintains a stable clamping direction, better conforming to the branch surface. Each of the multiple plate 3 has a first... The second clamping plate 4, as the component that directly contacts the thin branches, is assembled in a way that can adapt to the needs of subsequent universal adjustment, ensuring the flexibility of clamping. Each of the multiple second clamping plates 4 has a groove 5 at one or the other end. The groove 5 provides space for the ball 6 to move. Its internal structure is adapted to the ball 6, allowing the ball 6 to rotate freely to achieve multi-angle adjustment, while limiting the range of motion of the ball 6 to prevent the ball 6 from falling out of the groove 5, ensuring the stable realization of the universal adjustment function. The multiple grooves 5 are movably connected to the ball 6. The movable connection gives the second clamping plate 4 the ability to adjust to multiple angles. The ball 6 can rotate freely in the groove 5, so that the second clamping plate 4 can flexibly adjust its fitting posture according to the tilt angle and curvature of the branch. The multiple balls 6 are fixedly connected to the corresponding plate 3.

[0016] In this embodiment, multiple bolts 7 are movably connected to the two first clamping plates 1, and each bolt 7 is threaded with a nut 8. The distance between the two first clamping plates 1 can be controlled by adjusting the position of the nut 8 on the bolt 7. After tightening, the distance can be firmly locked to prevent the first clamping plates 1 from loosening due to vibration or tree branch movement during use, ensuring the stability of the overall fixing structure. Each of the multiple second clamping plates 4 has an arc-shaped groove at one or the other end. The arc-shaped groove design is adapted to the circular contour of the tree branch, which can increase the contact area between the second clamping plate 4 and the surface of the tree branch, so that the clamping force is evenly distributed, avoiding excessive local pressure that could damage the tree branch and bark. At the same time, it can improve the stability of the clamping and prevent the tree branch from sliding during the fixing process. Both first clamping plates 1 are semi-circular. The semi-circular structure design can better fit the arc-shaped surface of the tree branch, making it easier to clamp the tree branch from both sides. Compared with flat clamping plates, it can increase the contact area with the tree branch, improve the tightness and stability of the clamping, and reduce the pressure on the tree branch. To prevent surface pressure damage, multiple second clamping plates 4 are fixedly connected to rubber pads 11 at one or the other end. The rubber pads 11 are soft and non-slip. Fixedly connected to the second clamping plates 4, they can increase the friction with the surface of the branches, effectively prevent slippage during clamping, and buffer the clamping pressure, avoiding direct contact between the hard second clamping plates 4 and the branches, thus preventing damage to the bark. They provide gentle clamping protection for the branches. Multiple screws 2 are fixedly connected to handles 10, which are used to drive the screws 2 to rotate. Multiple plates 3 are fixedly connected to slide rods 9, which are slidably connected to the corresponding first clamping plates 1. The slide rods 9 are used to guide the movement of the plates 3, so that the plates 3 can move smoothly under the drive of the screws 2. Multiple balls 6 and corresponding grooves 5 constitute a universal assembly, which can realize multi-angle adjustment, allowing the second clamping plates 4 to be flexibly adapted to different grafting methods such as oblique grafting and cleft grafting, as well as the irregular shape of the branches, greatly improving the adaptability of the device to different grafting scenarios.

[0017] The working principle of this embodiment is as follows: In use, the two first clamping plates 1 are firstly attached to the two sides of the thick branch. After multiple bolts 7 pass through the two first clamping plates 1, the placement of the nuts 8 on the bolts 7 is flexibly adjusted according to the thickness of the branch to adjust the distance between the two first clamping plates 1, so that the first clamping plates 1 and the surface of the branch form a close contact state. Then, the distance is fixed by locking the nuts 8 to prevent loosening during use. Subsequently, for the thin branch, the corresponding plate 3 and the second clamping plate 4 are moved towards the branch by rotating multiple screws 2. At the same time, by taking advantage of the movable connection between the ball 6 at the plate 3 and the groove 5 at the second clamping plate 4, the contact posture of the second clamping plate 4 is flexibly adjusted according to the grafting angle, such as oblique grafting or cleft grafting, so that the second clamping plate 4 adapts to the shape and grafting angle of the thin branch. This not only achieves all-round adaptation and fixation of branches of different specifications, but also controls the clamping force by adjusting the screws 2, reducing the possibility of damage to the branch bark.

[0018] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
