Existing testing devices are usually inconvenient to fix the spring covers, making the testing process cumbersome and having a certain adverse effect on the testing process. In order to overcome the shortcomings of the existing technology, we propose a wear resistance testing device for wear-resistant spring covers. Utility Model Content

[0022] like Figures 1-3As shown, on the other side of the upper end of the base 1, two sets of sliding rails 8 and one set of sliding grooves 7 are also provided.
