[0002] As an important component of chemical building materials, plastic pipes are widely accepted by users for their superior performance, hygiene, environmental protection, low consumption and other advantages. There are mainly UPVC drainage pipes, UPVC water supply pipes, aluminum-plastic composite pipes, polyethylene water supply pipes, polypropylene PPR hot water pipes. When conducting longitudinal shrinkage rate and external impact resistance tests on thermoplastic plastic pipes, it is necessary to draw smooth and continuous circular lines with fixed spacing or evenly divided tangent lines on thermoplastic plastic pipes with regular shape and smooth surface.

[0003] Among them, the plastic pipe inspection and marking device is a common device for fixing and marking pipes in the field of pipeline inspection. Its working principle is to first fix the position of the pipe by a positioning component, then use the marking part of the marking device to adjust the contact with the surface of the plastic pipe, and then rotate the plastic pipe to complete the circumferential marking of the plastic pipe. The marking of the plastic pipe can reflect the stability of the plastic change of the longitudinal plasticity of the plastic pipe product under heating. For example, the utility model patent with publication number CN218427815U discloses a plastic pipe inspection and marking device, and the inner side of the upper two support columns is provided with a tool for clamping the main body of the plastic pipe.
