[0027] In this embodiment, the starting end of the scale groove 3111 is located directly below the cutting knife group 5, and the slider 315 is threadedly connected to the outer wall of the screw rod 312. Through the cooperation of the first telescopic rod 317, the fixed seat 316, and the first fixed plate 318, it is convenient to fix silencer steel pipes of different sizes. At the same time, through the cooperation of the screw rod 312, the slider 315, the scale groove 3111, the limit plate 319, and the indicator needle 3110, it is convenient to adjust the cutting size of the silencer steel pipe, thereby ensuring the cutting accuracy of the silencer steel pipe and increasing the applicability of the device.

[0028] Furthermore, the screw rod 312 is rotatably connected to the workbench 1 through a bearing, and the support plate 3112 can support the cutting portion of the silencer steel pipe, so that the silencer steel pipe is not easy to tilt during cutting, thereby further improving the cutting accuracy of the silencer steel pipe.
