[0027] Reference Figure 1-4 This utility model provides an embodiment of an apple tree branch-pulling device, comprising a fixed sleeve A1 and a fixed sleeve B2. A protective sleeve 3 is connected to the bottom of the fixed sleeve A1. A spherical shaft 4 is installed on the outer wall of the fixed sleeve A1. A movable rod 5 is connected to one end of the spherical shaft 4. An extension rod A6 is connected to one end of the movable rod 5. An extension rod B7 is connected to one end of the extension rod A6. A branch-pulling support head 8 is installed on the top of the extension rod B7. A fixed plate A9 is connected to the outer wall of the fixed sleeve A1. A fixed plate B10 is connected to the outer wall of the fixed sleeve B2. A fixing bolt 11 is installed between the fixed plate A9 and the fixed plate B10. A support spring 12 is installed inside the extension rod A6. A limiting ball 13 is connected to the top of the support spring 12. A protective layer 14 is provided on the outer layer of the protective sleeve 3. A bamboo fiber antibacterial layer 15 is connected to one side of the protective layer 14, and a rubber layer 16 is connected to one side of the bamboo fiber antibacterial layer 15.

[0028] In this invention, the fixing sleeve A1 and fixing sleeve B2 are the same size. Fixing sleeves A1 and B2 are fitted onto the outside of the apple tree. The protective sleeve 3 is integrally connected to the bottom of fixing sleeves A1 and B2. The protective sleeve 3 is semi-cylindrical in shape, and there are two protective sleeves 3. This design ensures that fixing sleeves A1 and B2 are evenly distributed on the outside of the apple tree, thus providing stable support. The semi-cylindrical design of the protective sleeve 3 adapts to the natural growth pattern of the apple tree, reducing friction and damage to the bark. The two protective sleeves 3 make the device more securely fixed to the apple tree and also distribute the pressure on the trunk to a certain extent, preventing damage to the trunk due to excessive weight or improper fixing.

[0029] Furthermore, the fixing plate A9 is fixedly connected to the outer wall of the fixing sleeve A1, and the fixing plate B10 is fixedly connected to the outer wall of the fixing sleeve B2. The fixing plate A9 and the fixing plate B10 are the same size. The fixing bolts 11 are threadedly connected between the fixing plate A9 and the fixing plate B10. There are several fixing bolts 11. In this way, it can be ensured that the fixing sleeve A1 and the fixing sleeve B2 are firmly fixed to both sides of the apple tree, thereby providing stable support for the branch pulling support head 8. The number of fixing bolts 11 can be adjusted according to actual needs to accommodate apple branches of different thicknesses. In addition, the use of fixing bolts 11 also makes it convenient for users to adjust the distance between the fixing sleeve A1 and the fixing sleeve B2 according to the growth of the apple tree to achieve the best branch pulling effect.

[0030] Furthermore, the spherical shaft 4 is rotatably connected to the outer wall of the fixed sleeve A1. There are several spherical shafts 4, each spherically shaped. The movable rod 5 is fixedly connected to the outer wall of the spherical shaft 4. The extension rod A6 is movably connected inside the movable rod 5, and the extension rod B7 is movably connected inside the extension rod A6. The branch-pulling support head 8 is fixedly installed at one end of the extension rod B7. There are several branch-pulling support heads 8. The spherical shaft 4 is rotatably connected to the outer wall of the fixed sleeve A1, allowing the branch-pulling support head 8 to flexibly adjust its angle and position to adapt to apple branches at different angles and positions. This design not only improves the applicability of the device but also reduces damage to the branches because the branch-pulling support head 8 can be more precisely positioned to the area requiring support. In addition, the movable connection between the movable rod 5 and the extension rods A6 and B7 gives the entire branch-pulling device good extensibility and adaptability during use, enabling it to adapt to the stretching needs of branches of different lengths and angles. This design effectively disperses the tension on the branches, preventing them from breaking or being damaged due to concentrated tension.

[0031] Furthermore, the bottom of the support spring 12 is fixedly connected to the inner wall of the extension rod A6, and the top of the support spring 12 is fixedly connected to the limiting ball 13. There are several support springs 12. The surface of the movable rod 5 is provided with a groove, the size of which is adapted to the size of the limiting ball 13. By setting the support spring 12 and the limiting ball 13, the length of the extension rod A6 can be adjusted. When in use, pressing down on the limiting ball 13 can stretch and retract the extension rod A6, thereby controlling the overall length of the movable rod 5, the extension rod A6, and the extension rod B7.

[0032] Furthermore, the protective layer 14 is fixedly connected to the outer layer of the protective sleeve 3, and the bamboo fiber antibacterial layer 15 is fixedly connected between the protective layer 14 and the rubber layer 16. The rubber layer 16 is fixedly connected to the bottom of the bamboo fiber antibacterial layer 15. The width of the protective layer 14 is the same as the width of the rubber layer 16. The material of the protective layer 14 has good wear resistance and anti-aging properties, which can effectively protect the apple tree trunk. The bamboo fiber antibacterial layer 15 utilizes the natural antibacterial properties of bamboo fiber to effectively inhibit the growth of bacteria and microorganisms, maintain the hygienic condition of the device, and reduce potential damage to the apple tree. The elastic design of the rubber layer 16 can absorb some vibration and impact, reduce the risk of damage to the apple tree branches, and provide a certain cushioning effect, making the branch pulling operation more stable and safer.

[0033] Working principle and usage procedure: During the apple tree growing season, first, place the fixing sleeves A1 and B2 on the appropriate positions on the apple tree, ensuring they are positioned on both sides of the trunk. Then, secure the fixing plates A9 and B10 with the fixing bolts 11 to fix the entire device. The spherical shaft 4 allows the movable rod 5 to rotate freely within a certain range, thus enabling the extension rods A6 and B7 to be adjusted according to the growth direction of the apple tree. The branch support head 8 is used to support the apple tree branches, preventing them from bending excessively or breaking.

[0034] During use, the support spring 12 provides the necessary elasticity. The support spring 12 and the limiting ball 13 can fix the extension rod A6 and the extension rod B7. While extending, they can remain stable, which makes it convenient for the branch support head 8 to support branches at different distances.

[0035] The limiting ball 13 engages with the groove on the movable rod 5 to ensure that the branch support head 8 is fixed in the proper position and prevents it from sliding. The protective layer 14, the bamboo fiber antibacterial layer 15, and the rubber layer 16 work together to protect the bark of the apple tree from damage and have antibacterial and anti-slip functions, ensuring the stability of the device and the healthy growth of the apple tree.

[0036] Through the above structure and usage process, the apple tree branch pulling device of this utility model can effectively support and adjust the apple tree branches, promote the healthy growth of the apple tree, and improve the quality and yield of the fruit.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
