[0007] By adopting the above technical solution, multiple tests of the workpiece are realized. The partition plate divides the inside of the test barrel into a plurality of material holding areas, different test materials are arranged in each material holding area, and the rotating mechanism drives the test barrel to rotate, so that different material holding areas are aligned with the workpiece, thereby realizing the wear resistance test of the workpiece using different test materials, reducing the labor intensity of the workers manually switching the test materials, and improving the test efficiency.
