However, there are relatively large defects in the positioning of the traditional fixture. For example, when the positioning component of the traditional fixture is used, it cannot rotate. After inspecting one side of the door panel, it is necessary to reposition it by turning it over and then inspect the other side. Such a method results in low positioning efficiency, thus affecting the inspection efficiency. Therefore, the utility model proposes a fixture capable of quickly positioning an automobile door panel assembly to solve the above problems. Summary of the Utility Model
