A clamp (10) is provided that has a pair of clamp bodies (12) which each have an inner surface (20). The inner surfaces (20) of each clamp body (12) are oriented to face one another in a spaced parallel relationship. A pair of parallel scissors linkages (36) are coupled to the device that operate to move the clamp bodies in parallel relation relative to one another. A threaded rod (92) is coupled to the pair of scissors linkage (36) between the clamp bodies (12) and is oriented with its axis of rotation parallel to the inner surfaces (20) of the clamp bodies (12). By operation of the rod (92), the device may be used as either a clamping device or an expansion device.
