Description of the Related Art When fusing a plastic saddle or the like to a plastic tube, the surface of the fusing portion must be clean to cause impurities to enter in between, causing a problem of poor fusion. To do. Therefore, the surface of the pipe is cut using a cutting tool called a scraper, but the conventional scraper holds the scraper by hand and rotates it by a certain angle along the circumference of the pipe while pressing it moderately. It is a method of cutting by rotating.
【０００３】[0003]
【従来技術の課題】このため、次のような欠点がある。 ａ．手で押しつける力が一定しないことから、切り込み

題が発生しやすい。 ｂ．狭い場所では作業がしにくい。 ｃ．管にサドルを融着する場合には、サドルが接する部
分のみを切削すれば足りるが、このような部分切削がで
きない。Therefore, there are the following drawbacks. a. Since the force applied by hand is not constant, the amount of cut is not constant, and streaky irregularities are formed on the background, which tends to cause a problem of poor fusion. b. It is difficult to work in a narrow space. c. When the saddle is fused to the pipe, it suffices to cut only the portion in contact with the saddle, but such partial cutting cannot be performed.

作用してスクレーパー本体に自動送りがかかる。When the scraper main body is attached to the pipe, the fixing member is loosened to open the blade attaching member side and the worm gear attaching member side around the connecting support shaft, and the plastic pipe is inserted thereinto to close the pipe. The blade, the worm gear, and the guide roller are pressed against the surface of the plate, and the fixing member is tightened. After attaching the scraper body to the pipe in this manner, the scraper body is rotated along the circumference of the pipe. Due to this rotation direction, the blade cuts the surface of the pipe, while the free end of the worm gear moves in the direction opposite to the rotation direction, maintaining a constant angle (tilt) with respect to the pipe axis, and the surface of the pipe remains unchanged. A spiral bites into and rotates. As a result, the amount of movement (feed) determined by the spiral of the worm gear and the inclination angle acts on the scraper body, and the scraper body is automatically fed and the scraper body moves in the pipe axis direction. When the scraper body is rotated in the opposite direction, the blade on the opposite side cuts the surface of the tube and the free end side of the worm gear changes the angle in the opposite direction. As a result, the scraper body is automatically fed by the same action.
