Description

Technical Field

[0001] This utility model relates to the field of peach tree planting technology, and in particular to an auxiliary fixing structure for peach tree grafting. Background Technology

[0002] In the process of peach tree planting, it is usually necessary to graft peach trees, commonly using branch grafting or bud grafting methods, to graft high-quality scions onto rootstocks with strong resistance, in order to maintain the superior characteristics of the variety, promote early fruiting, and enhance adaptability.

[0003] For example, patent number CN221488421U discloses an auxiliary component for peach tree grafting, including a large clamp with a connector at the upper end. A small clamp is fixedly connected to the top of the connector. The small clamp is compatible with the large clamp and has the same structure. The large clamp has multiple symmetrically distributed inner linings installed inside and a connecting rod installed inside. The connecting rod and the connector are detachably connected. This allows the grafting point of the peach seedling to be clamped tightly to the seedling without repeated manual calibration, preventing the peach seedling from shifting. By using the small clamp and the large clamp together, the peach tree and the seedling to be grafted are clamped tightly. The small clamp is used to clamp the peach seedling in a suitable position, so that the grafting point of the peach seedling is located inside the large clamp. During grafting, the small clamp fixes the position of the peach seedling, and the large clamp restricts the position of the grafting point of the peach seedling, preventing the peach seedling from shifting.

[0004] For example, patent number CN221152106U discloses a peach tree grafting auxiliary component, which relates to the field of peach tree grafting equipment technology. It includes a support mechanism, which includes a fixed plate. Two clamping mechanisms are respectively provided at the upper and lower ends of the fixed plate. The clamping mechanism includes a fixed column. The number of fixed columns is set to four and fixedly installed at a certain interval on the upper and lower end surfaces of the fixed plate. A horizontal plate is fixedly connected to the end of the fixed column away from the fixed plate. A connecting ring is provided on the outer surface of the fixed column. The inner surface of the connecting ring is rotatably connected to the outer surface of the fixed column.

[0005] While existing auxiliary fixing structures for peach tree grafting employ elastic clamping structures for rapid installation, the rigid clamping components struggle to fit well with the varying shapes and diameters of the trunks to be grafted, resulting in poor fixing stability and a tendency to loosen or shift. Furthermore, mismatched contact surfaces can damage the bark, affecting the grafting survival rate. In addition, existing clamping structures are typically bulky and heavy, taking up considerable space and increasing the inconvenience of carrying and storing them. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides an auxiliary fixing structure for peach tree grafting. It solves the problem that existing auxiliary fixing structures for peach tree grafting suffer from poor fixing stability due to the large differences in the shape and diameter of the trunk to be grafted, making it difficult for the rigid clamping components to fit well with the trunk. This can easily lead to loosening or displacement and may cause damage to the bark. In addition, existing clamping structures are usually large in size and heavy in weight, which not only takes up a lot of space but also increases the inconvenience of carrying and storing them.

[0007] The technical solution of this utility model is as follows: an auxiliary fixing structure for peach tree grafting, including a box body, a handle fixedly installed on the front side of the box body, positioning through holes opened at the upper and lower ends of the handle, an elastic pad provided on the rear side of the box body, a plug-in seat fixedly installed on the left side of the box body, a buckle provided on the right side of the box body, a winding roller provided inside the box body, a fixing strap provided on the outer side of the winding roller, coil springs provided at the upper and lower ends of the winding roller, an adjustment knob provided on the outer side of the box body, a lead screw provided inside the box body, guide rods provided on the upper and lower sides of the lead screw, a movable plate provided on the outer side of the lead screw, a clamping plate one provided on the rear side of the movable plate, and a clamping plate two provided on the rear side of the clamping plate one.

[0008] Preferably, there are two elastic pads and two plug-in bases arranged vertically and fixedly connected to the outside of the box body, and two buckles arranged vertically and detachably connected to the plug-in bases.

[0009] Preferably, there are two take-up rollers arranged vertically, with the upper and lower ends of the take-up rollers rotatably connected to the inner side of the box body via a rotating shaft. One end of the coil spring is fixedly connected to the outer side of the rotating shaft, and the other end of the coil spring is fixedly connected to the inner side of the box body.

[0010] Preferably, a through groove is provided on the right side of the box body, the fixing strap is wound around the outside of the take-up roller, and one end is fixedly connected to the take-up roller. The other end of the fixing strap extends to the outside of the box body through the through groove and is fixedly connected to the buckle.

[0011] Preferably, the front and rear ends of the lead screw are rotatably connected to the box body, the front end of the lead screw extends to the outside of the box body and is fixedly connected to the adjustment knob, the guide rod and the lead screw are arranged in parallel, and the front and rear ends of the guide rod are fixedly connected to the inside of the box body.

[0012] Preferably, the upper and lower ends of the movable plate are slidably fitted to the inner side of the box, the lead screw and the movable plate are threadedly connected, and the movable plate and the guide rod are slidably connected to the outer side.

[0013] Preferably, clamping plate one and clamping plate two are located on the front and rear sides of the fixing strap, respectively. Clamping plate one is fixedly connected to the surface of the moving plate, and clamping plate two is fixedly connected to the inner wall of the box.

[0014] The beneficial effects of this utility model are:

[0015] 1. This auxiliary fixing structure for peach tree grafting uses a fixing strap structure that can automatically tighten, combined with a clamping plate for secondary locking, to adapt to peach tree trunks of different shapes and diameters, improving versatility and installation stability. The elastic pad, combined with the evenly tightening fixing strap, effectively prevents damage to the bark.

[0016] 2. The auxiliary fixing structure for this peach tree grafting uses a binding structure instead of a rigid clamping structure. After disassembly, the fixing binding can be automatically rolled back into the box under the action of a coil spring, which greatly reduces the storage volume. At the same time, the overall weight is small, making it easy to store and carry. No tools are required for disassembly and assembly, making the operation convenient and quick, and improving the efficiency and convenience of grafting operations.

[0017] This device is based on an improvement of existing equipment, so the improvement cost is relatively low and it will not cause a large amount of existing equipment to be discarded. It ensures the processing effect while reducing the investment in improvement costs, making it suitable for large-scale production. Attached Figure Description

[0024] 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.

[0025] Please see Figures 1-5 This utility model provides an embodiment of an auxiliary fixing structure for peach tree grafting, comprising a box body 1, a handle 2 fixedly installed on the front side of the box body 1, positioning through holes 3 at the upper and lower ends of the handle 2, an elastic pad 4 provided on the rear side of the box body 1, a plug-in seat 5 fixedly installed on the left side of the box body 1, a buckle 6 provided on the right side of the box body 1, a winding roller 7 provided inside the box body 1, a fixing strap 8 provided on the outer side of the winding roller 7, coil springs 9 provided at the upper and lower ends of the winding roller 7, an adjustment knob 10 provided on the outer side of the box body 1, a lead screw 11 provided inside the box body 1, guide rods 12 provided on the upper and lower sides of the lead screw 11, a moving plate 13 provided on the outer side of the lead screw 11, a clamping plate 14 provided on the rear side of the moving plate 13, and a clamping plate 2 15 provided on the rear side of the clamping plate 14.

[0026] Please see Figures 1-4 In this embodiment, there are two elastic pads 4 and two plug-in seats 5, one vertically and one vertically, and they are fixedly connected to the outside of the box body 1. There are two buckles 6, one vertically and one vertically, and they are detachably connected to the plug-in seats 5. There are two take-up rollers 7, one vertically and one vertically. The upper and lower ends of the take-up rollers 7 are rotatably connected to the inside of the box body 1 via a rotating shaft. One end of the coil spring 9 is fixedly connected to the outside of the rotating shaft, and the other end of the coil spring 9 is fixedly connected to the inside of the box body 1. A through groove 101 is provided on the right side of the box body 1, and the fixing strap 8 is wound around the take-up roller. The outer side of the roller 7, and one end of the roller 7 is fixedly connected to the take-up roller 7. The other end of the fixing strap 8 extends to the outer side of the box body 1 through the through groove 101 and is fixedly connected to the buckle 6. The box body 1 is pressed against the surface of the peach tree trunk to be grafted through the elastic pad 4. Pulling the buckle 6 causes the fixing strap 8 to be stretched and wrapped around the trunk. The buckle 6 is then inserted and fixed to the insertion seat 5. Under the elastic restoring force of the coil spring 9, the take-up roller 7 automatically tightens the fixing strap 8, so that it fits tightly against the surface of the trunk, thus achieving the initial fixation of the box body 1.

[0027] Please see Figures 2-5In this embodiment, the front and rear ends of the lead screw 11 are rotatably connected to the box body 1. The front end of the lead screw 11 extends to the outside of the box body 1 and is fixedly connected to the adjusting knob 10. The guide rod 12 is arranged parallel to the lead screw 11. The front and rear ends of the guide rod 12 are fixedly connected to the inside of the box body 1. The upper and lower ends of the moving plate 13 are slidably attached to the inside of the box body 1. The lead screw 11 and the moving plate 13 are threadedly connected. The moving plate 13 and the outside of the guide rod 12 are slidably connected. The clamping plate 14 and the clamping plate 15 are respectively located on the front and rear sides of the fixing strap 8. The clamping plate 14 is fixedly connected to the surface of the moving plate 13. The clamping plate 15 is fixedly connected to the inner wall of the box body 1. By rotating the adjusting knob 10, the lead screw 11 is driven to rotate, which drives the moving plate 13 to slide along the guide rod 12 and the inner wall of the box body 1, thereby causing the clamping plate 14 to move closer to the clamping plate 15 until the fixing strap 8 is clamped and fixed, thus achieving full fixation of the box body 1.

[0028] In use, the box 1 is placed against the surface of the peach tree trunk to be grafted via the elastic pad 4. Pulling the buckle 6 causes the fixing strap 8 to lengthen and wrap around the trunk. The buckle 6 is then inserted and fixed into the grafting seat 5. The winding roller 7 automatically tightens the fixing strap 8 under the elastic restoring force of the coil spring 9, ensuring it fits tightly against the trunk surface, thus achieving initial fixation of the box 1. Rotating the adjusting knob 10 drives the lead screw 11 to rotate, causing the moving plate 13 to slide along the guide rod 12 and the inner wall of the box 1, thereby bringing the clamping plate 14 closer to the clamping plate 15 until... Secure the fixing strap 8 to fully fix the box 1. Then, pass the branch to be grafted through the positioning hole 3 on the handle 2 and insert it into the target grafting position to achieve positioning support for the grafted branch. When disassembling, pull out the buckle 6 from the insertion seat 5, turn the adjustment knob 10 in the opposite direction to release the clamping plate 14 and clamping plate 25 from the fixing strap 8. Under the action of the coiling spring 9, the winding roller 7 automatically winds the fixing strap 8 into the box 1, releases the fixation of the box 1, and removes the handle 2 along the grafted branch.

[0029] Compared to the auxiliary fixing device in the prior art, which uses a rigid clamping structure for installation and fixation, this device addresses the challenge of achieving a good fit between the rigid clamping components and the various shapes and diameters of the tree trunks to be grafted, by incorporating an automatically tightening fixing strap 10 and a secondary locking mechanism with clamping plates. This allows the device to adapt to peach tree trunks of different shapes and diameters, improving versatility and installation stability. Furthermore, the rigid clamping structure in the prior art, which may cause bark damage due to mismatched contact surfaces, is effectively prevented in this device by using an elastic pad 4 and a uniformly tightening fixing strap 10. Finally, the auxiliary fixing device in the prior art, which typically has a large size and heavy weight, uses a strap structure instead of a rigid clamping structure. After disassembly, the fixing strap 10 automatically retracts into the box 1 under the action of a coiling spring 9, significantly reducing storage volume. The overall weight is also small, making it easy to store and carry. The disassembly and assembly process requires no tools, making operation convenient and quick, thus improving the efficiency and convenience of grafting operations.

[0030] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
