[0002] The main function of painting automotive steering knuckles is to prevent rust and maintain structural strength. As a key component of the automotive steering system, the steering knuckle needs to withstand complex loads and impacts. Surface painting can effectively isolate moisture and corrosive media, preventing metal oxidation and rust. When painting steering knuckles, a hanger is used to lift them.

[0003] When using existing automotive steering knuckle paint hangers, their function is to lift the automotive steering knuckle to prevent paint from spraying onto other workpieces. However, existing hangers cannot quickly assemble or disassemble the hooks, and the height of the hooks themselves cannot be adjusted, resulting in the inability to manually adjust the lifting height. Utility Model Content
