Claims

[Claims for Utility Model Registration] 1. A holding part 6 that holds a synthetic resin pipe as an object to be cut, and a linear movement along an imaginary straight line passing through the center P of the synthetic resin pipe held by the holding part 6 to A blade body 1 that moves forward in the direction of cutting the pipe is attached to the main body 5, and optional drive means B such as a rack 7 and a pinion 8 are connected to the blade body 1, and the blade body 1 itself is made of the synthetic resin. Blades 3a, 3b are formed wider than the diameter D of the pipe, and are provided on the front surface of the blade body 1 in the advancing direction from the blade apex 2a, which is located within the diameter D of the pipe and deviates from the virtual straight line, on both sides. A synthetic resin pipe cutting machine characterized by being equipped with a blade part that forms a. 2. The synthetic resin according to claim 1, wherein the blade apex 2a is biased upward from the imaginary straight line, and the receding angle of the retracted blade 3a above the blade apex 2a is smaller than the receding angle of the lower retracted blade 3b. pipe cutting machine. 3. The synthetic resin pipe cutting machine according to claim 1 or 2, wherein the rack 7 pinion 8 serving as the driving means B is provided on one side of the blade body 1 in the width direction. 4. The synthetic resin pipe cutting machine according to claim 1, wherein the upper blade is formed vertically and forms an asymmetrical blade apex with the lower retracting blade 3b.
