发明名称 Manual trench tool
摘要 Apparatus for providing a six-inch deep trench in a lawn surface, for the primary purpose of installing irrigation pipe for sprinkler systems. A trenching tool which includes a lower portion having two heavy steel blades and a hinge mechanism. The steel impact blades are sharpened at the bottom to accommodate a V configuration to enhance the downward penetrating action by the operator as he drives the blades into the ground until the desired 6″ is reached. The operator then forces the handles together which separates or widens the bottom portion of the channel. The channel/trench is elongated for any distance the operator desires by repeatedly thrusting the tool into the lawn right next to the elongated section of the original opened trench.
