Description

Technical Field

[0001] This utility model relates to the field of fruit tree branch pulling technology, and in particular to a branch pulling device. Background Technology

[0002] In the cultivation and production of fruit trees (citrus, peach, plum, pear, etc.), branch pulling techniques are required for aspects such as thinning out vigorous shoots, cultivating fruiting branches, and improving tree shape. Currently, in orchard production, branch pulling often involves tying branches with hemp rope, pulling the branches to a suitable angle, and then fixing the other end of the rope to the soil with a wooden wedge. However, this method is labor-intensive and requires a large amount of hemp rope and wooden wedges. It also has a certain technical threshold, requiring experience in controlling the pulling force. The hemp rope has poor elasticity, and tying it too tightly may cause the branches to break. There are also certain requirements for the depth and angle at which the wooden wedges are driven into the soil. Furthermore, the looseness of the orchard soil is important; if the soil is too hard, it becomes more difficult to drive in the wooden wedges, while if the soil is too soft, it affects the grip of the wooden wedges, resulting in a reduction in the effectiveness of branch pulling.

[0003] Therefore, how to provide a branch-pulling device that can be supported between adjacent lateral branches, pull branches through the interaction between adjacent lateral branches, and has the characteristics of easy adjustment of angle and pulling amplitude is a problem that urgently needs to be solved by those skilled in the art.
