ABSTRACT:
An elongated base is provided including a pair of opposite side opposing abutment surfaces disposed in a plane extending therebetween transversely of the base. A pair of elongated longitudinal side-by-side levers are disposed between the abutment surfaces and include opposite end portions projecting from opposite sides of the aforementioned plane. A first pair of end portions define opposing jaw faces for clamping an auto body portion therebetween and anchor structure is carried by the base for applying a pulling force thereon in a direction opposite to the direction in which the first end portions project. Wedge structure is shiftably supported from the base between the second end portions of the levers and operable to selectively wedge the second end portions apart and thereby cause the levers to fulcrum on the abutment surfaces to swing the first pair of end portions toward each other. The levers are slightly relatively angulated with the remote surfaces thereof slightly divergent toward the second end portions and the levers are slidably engageable with the abutment surfaces to cam the first pair of end portions of the levers toward each other in response to longitudinal shifting of the levers and the wedge structure relative to the base in a direction advancing the first end portions.
