The rotation of the grinding tool 615 can perform a wear resistance test on the clutch plate 710. When performing the wear resistance test, the dust suction fan 801 is controlled to start, and the dust suction fan 801 starts to suck the dust into the inside of the purification box 807 through the dust suction pipe 808 and the connecting pipe 809, and then the dust is filtered through the filter plate 811 to test the dust. After completion, the control driving motor 601 is started, and the driving motor 601 starts to drive the rotating rod 602 to rotate. The rotating rod 602 rotates through two sets of transmission gears 604 to drive the rotating support column 603 to rotate, so that the hardness tester 612 and the grinding tool 615 can be swapped. When the grinding tool 615 is swapped, the wear resistance test of the clutch plate 710 after the hardness test can be carried out. When the hardness tester 612 moves to the clutch plate 710 after the wear resistance test, you only need to remove the clutch plate 710 after the test and place a new clutch plate 710 to carry out the hardness test on it.
