[0002] In the process of planting economic crops, in order to avoid tree overgrowth, trim tree shape and improve the quality of tree fruit, the appearance of the tree needs to be trimmed in time to ensure its effective growth. In addition to the traditional cutting, the long and crooked branches are generally straightened by pulling ropes or support rod structures to ensure normal production of the branches. However, this type of branch pulling correction method is relatively simple, especially the pulling rope needs to be bound to the branches and other fixed structures at both ends, such as the main stem of the tree. The pulling rope needs to be tightened regularly during the correction process to achieve gradual correction. Compared with the conventional one-time pulling method, this method is friendly to the tree and can avoid the situation of peeling and breaking at the bending part caused by one-time excessive correction.
