Abstract
A mechanism for clamping a drawbar in a receiver hitch uses a clamp pad to engage two adjacent interior surfaces of the receiver hitch tube. The clamp pad presses outwardly on the receiver hitch tube causing the opposing corner of the drawbar to engage the other sides of the receiver hitch tube. The clamp pad is extended and retracted by a shuttle member disposed inside the drawbar tube. The clamp may be self-aligning with respect to the receiver hitch. An adjustment mechanism is described for translating the shuttle member. An extendable pin mechanism may be actuated by the shuttle assembly. A locking mechanism may be provided to prevent an unauthorized person from releasing the clamp pad and the extendable pin.
