发明名称 Spring loaded mud flap installation tool
摘要 A spring loaded mud flap tool (10) includes a hook element (20) carried by one a first of a drive rod (30). The hook end of the hook element is sized to grasp the end of the spring carried within the hanger tube of the mud flap assembly. A handle assembly (80) is carried by a second end of the drive rod. The handle assembly allows the user to manipulate the hook until it successfully grasps the spring. A bearing assembly (40) is carried on the threaded surface of the drive rod (30), and supports a pair of diametrically opposed crank handles (70). In operation, the bearing assembly rests on the open end of the hanger tube. Revolution of the crank handles turns the drive rod, which retracts the hook element and therefore retracts the spring. The force of the spring pulling the tool (10) into the hanger tube is offset by an equal force exerted by the bearing assembly on the rim of the hanger tube. A safety chain (90) connects the hanger tube and the bearing assembly.
