[0002] Pig leather is a leather material obtained by tanning pig skin. Compared with other animal leathers, pig leather has good breathability and flexibility. Compared with other types of leather such as cowhide, pig leather is usually more economical and affordable. Therefore, it is often used to make high-intensity products such as sports shoes, casual shoes and work shoes.

[0003] Therefore, in order to evaluate the mechanical strength and durability of pig leather, and because different products have different requirements for the wear resistance of pig leather, it is necessary to conduct anti-scratch tests on samples of pig leather from the same batch after production, so that manufacturers can evaluate whether the produced pig leather can maintain its appearance and function after long-term use.

[0004] Existing anti-scratch testing equipment usually fixes pig leather, then repeatedly scratches the surface of the pig leather with a scratching tool for a period of time, and observes the surface damage of the pig leather to judge the wear resistance of the pig leather. However, the existing testing equipment can only be equipped with one scratching tool to test the pig leather during the test, making the test sample data not intuitive and rich enough.
