High branch pruning shears structure

Abstract

The invention herein relates to kind of improved structure high branch pruning shears that is structurally comprised mainly of the shears, a convex blade, a pull rod, an adjustment rod, a handle mount, a saw blade, and a pull rope. The handle mount is installed at the lower end of the shears and at the lower section of the handle mount is a roller wheel ensconced in an U-shaped component. The convex blade is hinged to the shears and is supported in operation by the concave blade. There is a fastening pin on the concave blade provided for the installation of the saw blade. One end of the aforesaid concave blade is utilized as a conjoinment and pivot point inside the slide slot of the pull rod and the front end of the pull rod is riveted to the shears with a recoil spring seated on the fastening rivet. One end of the pull role is guyed to the U-shaped component and then routed through the roller wheels of the handle mount and the adjustment rod, respectively, such that as the pull rope is dram downward, the adjustment rod is subjected to a downward force that causes the movement of the pull rod and initiates the pivoting of the convex blade. When a coarse tree branch is encountered the adjustment rod slides into the next lower notch hole to achieve a greater shearing force and thereby effectively maximizes pruning efficiency, resulting in a pruning tool that requires minimum physical effort.
