Pipe opening tool with peeling mechanism

Abstract

This product is a buried pipe window-opening tool with a peeling section, used in conjunction with a hole saw to create a window on the side of a buried pipe that houses electrical wires or the like to check the condition inside. As shown in the "Reference Perspective View Showing Usage," the cylindrical part of this product is fitted into an annular cutting groove that has been pre-cut to a half-depth of the pipe thickness using a hole saw. Then, by swinging the gripping side of this product, in which the cylindrical part is fitted, along the longitudinal direction of the buried pipe, a crack can be created in the thin remaining portion of the groove bottom around the core formed inside the cutting groove. The peeling section at the rear end of this product can be inserted into the crack around the core, and the core can be separated from the buried pipe by levering or other means.
