Background

The branch pulling is one of important works in trimming the saplings, can relax the tree vigor, optimize the tree body structure, improve ventilation and light transmission, adjust hormone balance and nutrient distribution and promote flowering and fruiting, and is an irreplaceable measure for realizing early-maturing, high-yield, high-quality and high-efficiency apples. The branch pulling is a time-consuming and labor-consuming technology, generally, if the young trees grown in 2-3 years adopt a rope pulling method or an iron wire pulling method, 3-5 workers are required per mu on average, a large amount of agricultural resources are consumed, and the cost is relatively high. Most of existing branch pulling devices are improved on the basis of a rope pulling method, but single branches still need to be bound one by one, and the binding still needs to be released when necessary, otherwise, central trunks and main branches are easy to tie off or even tie down, labor cost is increased, and applicability is not strong. And the other plastic or metal angle openers are mostly suitable for young shoots, but have poor fixity, are easy to fall off due to wind blowing, require dozens of trees per plant, have high cost and are not easy to accept by fruit growers. Therefore, a branch pulling device which can achieve the purpose of promoting flowering and fruiting, is time-saving, labor-saving, cost-saving and simple to operate is needed in production.
