[0015] Preferably, the connecting handle is located above the connecting cylinder, and the branch pulling rope is located below the connecting cylinder.

[0016] By adopting the above technical solution: The branch can be pulled by the branch pulling rope and the hook.

[0017] Compared with the prior art, the utility model has the following beneficial effects:

[0018] 1. By closing the two closing plates towards the fruit tree and connecting them with bolts, the fruit tree is located inside the two closing plates. Then, by rotating the two rotating screws, the two rotating screws respectively drive the two pressing plates to move relatively through the two movable sleeves, so that the two pressing plates squeeze the fruit tree, thereby enabling the whole branch pulling device to be fixed on the trunk of the fruit tree. Anti-slip strips are provided on the contact surfaces of the two pressing plates and the fruit tree, which can increase the friction with the fruit tree and prevent slipping;

[0019] 2.

[0029] Please refer to Figures 1-5 , the present utility model provides a technical solution:

[0030] An umbrella-shaped branch pulling device for fruit tree cultivation, comprising two closing plates 1. The opposite surfaces of the two closing plates 1 are both inserted and connected with fixing mechanisms 2. The lower ends of the two closing plates 1 are both fixedly connected with a plurality of L-shaped extension bars 3. One end of each of the plurality of L-shaped extension bars 3 far away from the closing plates 1 is fixedly connected with a branch pulling mechanism 4. The left and right outer surfaces of the two closing plates 1 are both fixedly connected with connecting ears 5. Through holes serving as mounting holes 6 are formed at the front ends of the four connecting ears 5.

[0031] In this embodiment, the fixing mechanism 2 includes a rotating screw 21. The end of the rotating screw 21 is movably connected with a movable sleeve 22. The front end of the movable sleeve 22 is fixedly connected with a pressing plate 23. One end of the pressing plate 23 far away from the movable sleeve 22 is fixedly connected with a plurality of anti-slip strips 24. The left and right ends of the pressing plate 23 are both fixedly connected with connecting blocks 25. The rear ends of the two connecting blocks 25 are both fixedly connected with limiting rods 26. The rear ends of the two limiting rods 26 are both fixedly connected with limiting pieces 27. The rotating screw 21 is inserted and connected with the closing plate 1. The pressing plate 23 is located inside the closing plate 1. The plurality of anti-slip strips 24 are distributed in an annular array. The two limiting rods 26 are both inserted and movably connected with the closing plate 1.

[0032] Through the above scheme: By closing the two closing plates 1 against the fruit tree and connecting them with bolts, the fruit tree is located inside the two closing plates 1. Then, by rotating the two rotating screws 21, the two rotating screws 21 respectively drive the two pressing plates 23 to move relatively through the two movable sleeves 22, so that the two pressing plates 23 squeeze the fruit tree, thereby enabling the entire branch pulling device to fix on the trunk of the fruit tree. Moreover, anti-slip strips 24 are arranged on the contact surfaces between the two pressing plates 23 and the fruit tree, which can increase the friction with the fruit tree and prevent slipping.

[0033] In this embodiment, the branch pulling mechanism 4 includes a connecting cylinder 41. The front part of the outer surface of the connecting cylinder 41 is inserted and connected with a locking screw 42. The upper part of the connecting cylinder 41 is inserted and connected with a movable rod 43. The upper end of the movable rod 43 is fixedly connected with a connecting handle 44. The lower end of the movable rod 43 is fixedly connected with a branch pulling rope 45. One end of the branch pulling rope 45 far away from the movable rod 43 is fixedly connected with a branch pulling hook 46. The rear part of the outer surface of the connecting cylinder 41 is fixedly connected with the L-shaped extension bar 3. The end of the locking screw 42 is in close contact with the movable rod 43. The connecting handle 44 is located above the connecting cylinder 41. The branch pulling rope 45 is located below the connecting cylinder 41.

[0034] Through the above solution: After fixing the two closing plates 1 to the trunk of the fruit tree, hook the branch pulling hook 46 on the branch, and move the movable rod 43 downward through the connecting handle 44, so that the movable rod 43 can drive the branch pulling rope 45 downward. After moving to the designated position, limit and lock the movable rod 43 through the locking screw 42, so that the bending degree of the branch can be conveniently adjusted. Moreover, several branch pulling mechanisms 4 are provided and distributed in an annular umbrella shape, which not only makes it convenient to carry, but also can be used to pull multiple branches at the same time, improving the working efficiency.

[0035] It should be noted that the present utility model is an umbrella-shaped branch puller for fruit tree cultivation. During use, by adopting two closing plates 1 that are spliced face to face, they are accurately aligned with the fruit tree, and then tightly connected by bolts, safely wrapping the fruit tree in between. Then, rotate the two rotating screws 21, and the rotating screws 21 drive the two pressing plates 23 to move towards each other through the movable sleeves 22 until they are in close contact with the trunk of the fruit tree, ensuring that the branch puller is firmly attached to the trunk of the fruit tree. To further improve the stability, anti-slip strips 24 are provided on the surfaces of the pressing plates 23 in contact with the fruit tree. These stripes significantly enhance the friction with the surface of the fruit tree and effectively prevent slipping. Once the closing plates 1 are firmly fixed to the tree trunk, the branch pulling mechanism 4 can be used to adjust the branches. During specific operation, hang the branch pulling hook 46 on the target branch, and then drive the movable rod 43 to slowly descend by operating the connecting handle 44. The movable rod 43 then pulls the branch pulling rope 45 to move downward together until the predetermined bending position is reached. At this time, use the locking screw 42 to firmly lock the movable rod 43, thereby precisely controlling the bending shape of the branch. It should be noted that the branch pulling mechanism 4 adopts a design of multiple units and is arranged in an annular umbrella shape around the tree trunk. Such a design not only facilitates carrying and storage, but also realizes the simultaneous branch pulling operation on multiple branches, greatly improving the operation efficiency and convenience.
