を開始する。When the cutting blade body 4 bites into the outer peripheral surface of the synthetic resin pipe P, the angle member 3 receives the cutting resistance of the pipe P extruded from the mouthpiece D and generates a rotational force about the pin P1 in the angle member 3, and A thrust S acts along a straight line L. At this time, since the pin P3 connecting the intermediate portion of the gripping member 5 and the connecting member 6 is located below the straight line L,
Even when the grip 51 is released, the gripping member 5 does not return to its original position, and the synthetic resin pipe P extruded from the mouthpiece D is cut continuously along the axial direction. Next, after the operation of the extruder is stabilized, the cut synthetic resin pipe P is cut off, the handle 51 of the gripping member 5 is gripped by hand, and the cutting blade body 4 is flipped up. Start extrusion molding.
