[0002] In the field of mechanical processing, a cutting device is usually used to cut thin-walled metal pipes. The cutting device generally includes a pneumatic clamp and a cutting knife. For example, the existing Chinese patent with the authorization announcement number CN203751420U discloses a metal pipe cutting machine, including: a cutting piece, and also includes: a moving piece for lifting the cutting piece, and a fixed component fixed on both sides of the moving piece. The utility model provides a cutting machine suitable for metal pipes and other easy-to-roll products. The position of the fixed product is fixed, and the cutting machine will not cut the fixed device. The operation is stable, safe, and low-cost.
