[0012] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.

[0013] This utility model discloses an Akizuki pear tree planting branch puller, which mainly includes a fixing component 1, a protective pad 2, a connecting ring 3, a first hook 4, a telescopic rod 5, a connecting rod 6, and a second hook 7. The fixing component 1 is fixed to the tree trunk, and the protective pad 2 is connected to the inside of the fixing component 1 by a spring. The fixing component 1 has a sliding groove 8 for the connecting ring 3 to move. The connecting ring 3 is connected to the first hook 4, which is mounted on the telescopic rod 5 by a bearing. The telescopic rod 5 is hinged to the connecting rod 6, and the second hook 7 is mounted on the connecting rod 6 by a bearing and hangs on the tree branch. In this utility model, the two hooks are mounted on the telescopic rod 5 and the connecting rod 6 respectively by bearings. The two hooks can rotate freely, and the telescopic rod 5 is also suitable for branches of different heights, increasing flexibility. The inner wall of the fixing component 1 is connected to the protective pad 2 by a spring, which can protect the tree trunk from damage and can also adapt to the growth and development of young trees to a certain extent.

[0014] The fixing component 1 includes two semi-circular structures, with matching mounting holes at both ends of the two semi-circular structures. The fixing component 1 is connected by nuts and bolts 9 passing through the mounting holes. The fixing component 1 is used to fix it to the tree trunk. The specific position of the two semi-circular structures can be determined according to the diameter of the tree trunk, and then they are fixed with bolts 9. This device has a simple structure and is easy to disassemble.

[0015] The telescopic rod 5 includes an inner rod 501, an outer rod 502, and a fixing knob 503. The inner rod 501 is telescopically sleeved inside the outer rod 502 and the relative position of the two is fixed by the fixing knob 503. The length of the telescopic rod 5 can be adjusted according to the height of the tree branch, so that the second hook 7 can be hung on the tree branch.

[0016] The hook of the second hook 7 is semi-cylindrical, and a silicone plate is provided on the inner wall of the second hook 7. The semi-cylindrical design can increase the contact area between the second hook 7 and the tree branch, avoiding damage to the tree branch by the hook. The silicone plate on the inner wall further protects the tree branch from damage.

[0017] Working process: When pulling branches of the Akizuki pear tree, the worker first needs to install the fixing part 1 on the trunk. The size of the fixing part 1 can be adjusted according to the diameter of the Akizuki pear tree trunk, and then it is fixed with bolts 9. Then, the second hook 7 is hung on the branch. Then, the telescopic rod 5 is adjusted, and the first hook 4 is connected to the connecting ring 3 on the fixing part 1. The first hook 4 and the second hook 7 are both installed on the telescopic rod 5 and the connecting rod respectively through the shaft. The two hooks can rotate flexibly, which is convenient for pulling branches of the Akizuki pear tree at different angles. The design of the second hook 7 with an increased hook area increases the contact area between the hook and the branch, which can reduce the damage to the branch caused by the hook. This utility model solves the problem that common branch pulling methods are time-consuming and labor-intensive, and are prone to damaging fruit trees.

[0018] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
