发明名称 Maximum security/maximum versatility ball mount assembly
摘要 The maximum security/maximum versatility ball mount assembly provides an assembly for securing a ball mount or other accessory shank to a receiver hitch on automotive vehicles, tractors, ATVs, and other vehicles equipped with a receiver-type hitch. As the shank of a hitch accessory or implement is inserted into a receiver, dual retractable hitch pins automatically engage the receiver when the pins align with the two hitch-pin apertures in the receiver tube, thereby securing the ball mount/accessory's shank to the vehicle's receiver. A shank end cap shields the hitch pin assembly's internal components from dirt and/or rust particles, and the end cap also serves as an innovative and useful alignment aid when inserting the shank into a vehicle's receiver.
