Abstract
Abstract An elongated base if provided including a pair of opposite side opposing fulcrum surfaces disposed in a plane extending therebetween transversely of the base. A pair of elongated longitudinal side-by-side levers are disposed between the fulcrum 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. The elongated levers, when retracted in said opposite direction relative to the base, are longitudinally slidable relative to each other when the second pair of end portions are spaced apart and structure is provided for interlocking the levers against longitudinal displacement relative to each other when the second pair of end portions are forced together by engagement of the fulcrum surfaces on the remote sides of the levers as the result of the levers being displaced relative to the base in a direction to advance the first pair of end portions of the levers. The remote surfaces of the levers are slightly divergent toward the second end portions thereof and displacement of the levers relative to the base to advance the first pair of end portions of the levers causes the fulcrum surfaces to apply clamping forces to the remote surfaces of the levers centrally intermediate their opposite ends.
