[0015] The utility model is further described below in conjunction with the accompanying drawings:

[0016] A device for cutting automobile exhaust ducts, a cylinder a8 is fixed on a work surface 2, the cylinder a8 is connected to a mounting plate 1, the mounting plate 1 is slidably connected to the work surface 2 via a guide rail 9, a drive motor 3 is fixed on the mounting plate 1, the drive motor 3 is connected to drive a plurality of rotating shafts to rotate synchronously, the end of the rotating shaft is connected to a turntable 5, the turntable 5 is connected to an L-shaped connecting rod 6, a cutting tool 7 is provided at the end of the L-shaped connecting rod 6, and a clamping and fixing device for fixing a product 11 is provided on the opposite side of the cutting tool 7. The clamping and fixing device includes a supporting block 10 fixed on the work surface 2, and a matching pressing block 12 is provided above the supporting block 10. The pressing and fixing surfaces of the supporting block 10 and the pressing block 12 are contoured with the pressed part of the product 11, and the product is positioned through a square to ensure the consistency of the cutting part. The top of the pressing block 12 is connected to a connecting plate 13, and the two ends of the connecting plate 13 are slidably connected to a guide shaft 14. The middle part of the connecting plate 13 is connected to the output end of the cylinder b15. The cylinder b15 is fixed on an installation plate 16, and the two ends of the installation plate 16 are fixed on the top of the guide shaft 14. The cylinder b15 drives the pressing block 12 to move up and down along the guide shaft 14 through the connecting plate 13. The guide shaft 14 makes the up and down movement of the pressing block stable and will not cause axial deviation.
