PROBLEM TO BE SOLVED: To provide a high branch-cutting saw achieving the cutting of the high branch with little labor. SOLUTION: A saw blade 1 is attached to the tip of a saw handle 2 so that the tip of the saw may be lowered than the base. A branch-pushing supporting metal fitting 9 is installed in the saw handle, and the branch-pushing metal fitting 4 is installed in the tip of a branch-pushing lever metal fitting 5, and attached to a shaft 11. Two branch-pushing lever metal fittings are set by a linking metal fitting 14, and the branch-pushing lever metal fitting and the saw handle are connected with a spring 8. A wire 7 is attached to the other tip of the branch-pushing lever metal fitting. A branch-pushing slide handle 3 equipped with a wire-pulling lever 6 linked to a spring 8 for pulling the wire and a crank metal fitting 15 is set in the saw handle. A component 16 is a slide-preventing metal fitting installed in the inside of the saw handle. The slide handle is pulled so as to match the thickness of the branch, and the lever of the slide handle is pulled with the saw handle so as to match the incision. COPYRIGHT: (C)2007,JPO&INPIT
