PROBLEM TO BE SOLVED: To make work for pipe cutting and wire threading on a floor. SOLUTION: An end part of a fixed handle of a pipe cutter 1 is fixed to the tip of a pole detachably through a fixing metal. A pipe is cut by operating the operating handle of the pipe cutter on the floor, upon fixing one end of a wire to the end part of the fixed handle of the pipe cutter, passing the other end of the wire through the pole from the top end to the bottom one, and pulling the wire end at the bottom of the pole. Further an inner diameter to fit the pipe end is formed in the interior of the tip of the pole from which the pipe cutter is removed, and wire threading into the pipe is made by fitting the pipe end into the inner diameter and passing a wire through the inside of the pole from the bottom of the pole on the floor. |
