[0002] Skateboard wheels are usually made of polyurethane as the main material. The hardness of the wheels varies with the proportion of polyurethane in the wheels. After the production of skateboard wheels, they generally need to undergo a sampling wear test. The existing skateboard wheel wear tester generally has a roller with only one type of wear test sandpaper on it. For tests with different requirements, equipment with wear test sandpaper of different particle sizes is used, which increases the cost. In addition, the existing wear tester uses a small roller, and the installation mechanism of the wear test skateboard wheel cannot be moved horizontally. In order to avoid wasting the wear test sandpaper and use it in all positions, the installation position of the skateboard wheel can only be adjusted each time (installed at different positions of the shaft rod). This method is not flexible enough and the operation is not convenient enough. Therefore, an improved technology is urgently needed to solve this problem in the prior art. Utility Model Content
