Description

Technical Field

[0001] The utility model relates to the technical field of pruning tools, in particular to an improvement of high branch shears. Background Art

[0002] At present, most of the high branch shears used for pruning high branches of trees are connected with a long pole, one of which is fixed on the long pole and the other is fixed with a rope. When using, one hand holds the long pole and the other hand controls the rope to cut. However, this kind of high branch shears has great disadvantages. First, the opening of the scissors is small and the shearing force is small. When used, it can only cut small tender branches, but cannot prune thick branches, and the scope of use is limited; it is directly controlled by pulling the rope, and the force direction and force point will not change, which results in high labor intensity, time-consuming and labor-intensive, and low work efficiency; the long pole cannot be adjusted, the length is limited, and it cannot prune higher branches, which is inconvenient to carry and use.
