Traditional friction wheel installation methods mostly use bolt fixing or interference fits, which are inconvenient, time-consuming, and labor-intensive, especially in confined spaces or complex environments where replacing friction wheels becomes even more difficult. Therefore, developing a convenient friction wheel installation and removal device is of significant practical importance. Utility Model Content
