Abstract
A scissor coupler, for attaching to a trailer hitch ball having a widest point and a neck, comprising a top plate, a bottom plate, a hinge bolt, and a main spring connected between the top plate and bottom plate. The hinge bolt attaches the top plate and bottom plate so that they can pivot relative to one another from a closed position to an open position. The top plate and bottom plate have top plate and bottom plate bores that have a slightly larger diameter than the widest point of the trailer hitch ball, and are concentric when the top plate and bottom plate are in the open position. The top plate and bottom plate bores are not concentric when the scissor coupler is in the closed position. When the top plate and bottom plate are in the closed position, an elliptical hole is formed therebetween that is narrower than the widest point but wider than the neck of the trailer hitch ball. The main spring biases the scissor coupler to the closed position.
