用于地面切割灌木和小树，站立操作省力高效。
专利摘要
一种杠杆致动切割工具，允许站立从地面高度切割灌木和小树。切割工具的设计利用杠杆和阻力原理，并结合钟摆摆动，提供能够产生巨大切割力的工具。杠杆长端设有带垫手柄，第一锋利钢刀片附接至杠杆切割端。杠杆可旋转地附接至支点，操作时支点位于地面。第二锋利钢刀片不可移动地附接至支点底部，待移除灌木的树干置于两刀片之间。切割动作通过将杠杆向下朝地面移动完成。用户施加的力由杠杆放大并传递至第一切割刀片。地面提供的阻力通过支点底部传递至第二切割刀片。钟摆摆动运动允许第一刀片干净地越过第二刀片。
Original abstractA lever actuated cutting tool that allows ground level cutting of shrubs and small trees from a standing position. The design of the cutting tool takes advantage of the principles of leverage and resistive force, and also incorporates a pendulum swing, to provide a tool that is able to generate a tremendous amount of cutting force. A padded handle is provided at the long end of the lever and a first sharpened steel blade is attached to the cutting end of the lever. The lever is rotate-ably attached to the fulcrum and the fulcrum lies on the ground during operation. A second sharpened steel blade is immovably attached to the base of the fulcrum, and the trunk of the shrub to be removed is positioned in between the two blades. The cutting action is accomplished by moving the lever downward toward the ground. The force applied by the user is multiplied by the lever and transferred to the first cutting blade. The resistive force supplied by the ground is transferred, via the base of the fulcrum, to the second cutting blade. And the pendulum swing motion allows the first blade to pass cleanly over the second blade.
