[0002] Pipes are one of the commonly used basic parts for construction and industrial production equipment. Different pipe materials and shapes are required for different usage situations. Currently, plastic pipes are one of the more mainstream pipes. However, plastic pipes are easily affected by heat and deform longitudinally during use. Therefore, when conducting research and development of plastic pipes or sampling and testing finished products, it is necessary to perform line detection operations on them.

[0003] When marking the longitudinal shrinkage rate of existing plastic pipes, some use a wheel axle to roll and a fixed pencil to mark; some use a ruler to measure directly and then mark with a pencil. These methods require workers to operate the measuring tool while marking with tools such as pencils. These traditional methods are not only inefficient, but also have too much influence from human operating proficiency, which can easily affect the accuracy and thus affect the final test results.
