The clamping plate 28 is rotatably connected with a plurality of balls 29. When the end of the variable diameter pipe with a larger diameter contacts the clamping plate 28, the positioning ring 4 drives the variable diameter pipe to rotate. The balls 29 are convenient for reducing the friction between the variable diameter pipe and the clamping plate 28, thereby ensuring the cutting effect of the variable diameter pipe when rotating.

The operator then moves the sliding baffle 12 downward so that the end of the variable diameter pipe with a larger diameter contacts the sliding baffle 12, and then the first bolt 14 is threadedly connected with the corresponding first screw hole 15 to position the sliding baffle 12. The variable diameter pipe is limited by the first curved plate 13, the second curved plate 17 and the sliding baffle 12, and then the positioning ring 4 and the variable diameter pipe are driven to rotate by the driving assembly 5, so that the saw blade 7 cuts the variable diameter pipe, and the variable diameter pipe does not move during the cutting process, thereby ensuring the cutting effect of the variable diameter pipe.
