DETAILED DESCRIPTION

[0021] The utility model will be made further detailed explanation in combination with the drawings and embodiment:

[0022] For example, Figures 1-2The device includes a mounting rod 5, an inner wall of the mounting rod 5 is threadedly connected with a movable rod 4, by rotating the movable rod 4 clockwise or counterclockwise, the movable rod 4 can be lifted or lowered in the mounting rod 5, the operator can adjust the height of the device according to the height of the branches at different positions of the fruit trees and actual operation requirements, for the branches of the fruit trees at higher positions, the movable rod 4 can be rotated outwards to lift the device, for the branches at lower positions, the movable rod 4 can be rotated into the mounting rod 5 to lower the device. A regulating rod 3 is rotatably connected to the top of the movable rod 4, a damping is arranged between the regulating rod 3 and the movable rod 4, so that the regulating rod 3 will not shake randomly in the rotating process due to slight external force, the farmer can more accurately control the rotating amplitude of the regulating rod 3, so as to realize the accurate adjustment of the angle of the limiting ring 1. The top of the regulating rod 3 is connected with the limiting ring 1, which enables the regulating rod 3 to rotate in the horizontal direction, so as to adapt to the branches growing in different directions and provide stable support for the branches. A connecting block 6 is connected to the bottom of the mounting rod 5, a rotating shaft 7 is rotatably connected to the inner wall of the connecting block 6, a worm 15 is rotatably connected to the inner wall of the connecting block 6, one end of the rotating shaft 7 away from the connecting block 6 is connected with a worm wheel 16, the worm wheel 16 is meshed with the worm 15, the worm 15 is connected with a handle 17, the other end of the mounting rod 5 away from the connecting block 6 is connected with a fixing block 14, one end of the rotating shaft 7 away from the connecting block 6 is rotatably connected with the fixing block 14, the outer wall of the rotating shaft 7 is connected with a rotating block 8, the bottom of the rotating block 8 is connected with a connecting seat 9, the bottom of the connecting seat 9 is detachably connected with a semicircular cover 10, the connecting seat 9 and the semicircular cover 10 can be fixed around the trunk. Slowly rotate the handle 17, the rotation of the handle 17 drives the rotation of the worm 15. Since the worm 15 is meshed with the worm wheel 16, the rotation of the worm 15 drives the rotation of the worm wheel 16. Because the worm 15 and the worm wheel 16 have a large transmission ratio, a slight action of the handle 17 can cause a relatively fine angle change of the worm wheel 16. The worm wheel 16 is connected with the rotating shaft 7, the rotation of the worm wheel 16 drives the rotation of the rotating shaft 7. When the limiting ring 1 reaches a position that can provide ideal support and angle adjustment for the branches of the fruit trees, stop rotating the handle 17. Since the worm 15 and the worm wheel 16 have self-locking characteristics, the limiting ring 1 will be stably kept at the adjusted angle position. A non-slip pad 2 is detachably connected to the inner wall of the limiting ring 1 by glue, the soft non-slip pad 2 can tightly fit the surface of the branches, increase the friction with the branches, prevent the branches from sliding in the limiting ring 1, and ensure the fixing effect on the branches. On the other hand, the soft material can avoid damaging the branches, protect the integrity of the branches during growth, and reduce the risk of pests invading due to the fixing device. The connecting seat 9 is threadedly connected with a limiting bolt 13, the semicircular cover 10 is provided with a threaded hole 12, the limiting bolt 13 is threadedly connected with the threaded hole 12. The limiting bolt 13 is threadedly connected with a nut 11. By passing the limiting bolt 13 through the connecting seat 9 and rotating it into the threaded hole 12 of the semicircular cover 10, and then tightening the nut 11, the connecting seat 9 and the semicircular cover 10 can be tightly fixed on the trunk.By adjusting the tightening degree of the nut 11, the tightness of the fixing can be flexibly controlled, which can ensure the stability of the device on the trunk and avoid excessive extrusion damage to the trunk.

[0023] As shown in Figure 2 The handle 17 is provided with an anti-skid groove 18. The anti-skid groove 18 can effectively increase the friction between the surface of the handle 17 and the hand, so that the fruit grower can firmly hold the handle 17 when operating, avoid operation failure caused by hand slipping, and ensure the stability and continuity of the operation process.

[0024] The specific implementation process is as follows:

[0025] Firstly, the semi-circular cover 10 is placed around the trunk at a suitable position of the trunk, the limiting bolt 13 is passed through the connecting seat 9 and screwed into the screw hole 12 of the semi-circular cover 10, and the nut 11 is tightened to adjust the appropriate tightness. Then, the movable rod 4 is rotated according to the height of the branch until the appropriate position is reached, and the limiting ring 1 is sleeved on the branch through the opening. The handle 17 is held, the handle 17 is slowly rotated to drive the worm 15, the worm 15 drives the worm wheel 16, the worm wheel 16 drives the rotating shaft 7 to rotate, so as to adjust the angle of the limiting ring 1, and then stop rotating to fix the angle by self-locking. The fixing of the device and the support of the branch are checked, and the tightness of the nut 11 or the angle of the limiting ring 1 is adjusted as needed.

[0026] The above-mentioned is only an embodiment of the present application, and the specific technical solutions and / or common knowledge of the scheme are not described in detail. It should be noted that for those skilled in the art, without departing from the technical scheme of the present application, a number of modifications and improvements can be made, which should be regarded as the protection scope of the present application. The protection scope of the present application should be subject to the content of its claims, and the specific implementation mode and the like in the specification can be used to explain the content of the claims.
