Description

An adjustable orchard pruning scissors

technical field

The invention relates to the technical field of orchard pruning, in particular to an adjustable orchard pruning scissors.

Background technique

At present, the commonly used scissors are composed of two shear bodies intersecting and hinged. When pruning branches in the orchard, because some fruit trees are relatively tall, especially some vertically upward branches, it is necessary to borrow a ladder or even people to directly climb the tree when pruning, causing the tree tops to climb up. The branches are not pruned properly. Moreover, when climbing a branch, the small branch cannot bear the weight of the human body, which is very dangerous.

So, how to design a kind of orchard pruning adjustable scissors becomes our current problem to be solved.
