Abstract
A clamp is provided that has a pair of clamp bodies which each have an inner surface. The inner surfaces of each clamp body are oriented to face one another in a spaced parallel relationship. A pair of parallel scissors linkages are coupled to the device that operate to move the clamp bodies in parallel relation relative to one another. Each scissors linkage extends from one side surface of one clamp body to a corresponding side surface of the other clamp body. A threaded rod is coupled to the pair of scissors linkages between the clamp bodies and is oriented with its axis of rotation parallel to the inner surfaces of the clamp bodies. The threaded rod is operable to move the clamp bodies either towards one another or away from one another in spaced parallel relation by rotation of the rod. By operation of the rod, the device may be used as either a clamping device or an expansion device.
