For smaller sizes, the inner wall of the pipe is squeezed tightly by the side wall of the annular groove 171. When the size is larger, the outer wall of the pipe is squeezed tightly by the side wall of the annular groove 171 to adapt to the use of pipes with different inner diameters. Then the slider 211 is adjusted to move along the slide rail 210, driving the telescopic part 220 and the marking pen 230 to move, and the position is accurately adjusted according to the scale line 212. At the same time, the slider 211 can be moved axially without rotating the pipe. By rotating the handle 141, the rotating rod 140, the rotating disk 150, the transmission rod 160, the clamp 170 and the adjusting disk 180 can be driven to rotate, thereby driving the pipe to rotate for circular marking.
