Abstract
PURPOSE:To prolong the longevity of a blade through the increase of the length of the blade by providing extensively and longitudinally a shaft at the upper body mounted on the lower body via a push-pressing device, and putting a spiral blade on the tip of the shaft. CONSTITUTION:The lower body 17 arranged with turn-moving rollers 11-13 is mounted via a bellows 16 with the upper body 14 arranged with turn-moving rollers 9-10, and the upper and lower bodies 14, 17 are push-pressed to the inner surface of a pipe 19 due to the extension of the bellows 16. A shaft 2 is extensively and rotatably provided at the upper body 14 along the direction of longitude, and a bite 1 which forms a spiral blade of a spiral shape is put on the shaft 2. When the upper and lower bodies are expanded by means of the bellows 16, and the bite 1 is push-pressed to the inner surface of the pipe as it is rotated, and the pipe is moved, beads are cut in turn. As the bite 1 is constituted with the spiral blade, the length of a cutting blade becomes long by a large margin, and as cutting is discharged in the state of spiraling-out, the longevity of the blade is prolonged.
