The free end of the first spring member engages the inner wall surface of the tube or cone, and the free end of the second spring member engages the first spring member intermediate the ends thereof to provide a displaceable fulcrum therewith. An equal biasing force is applied to the inside surface of the tubes or cones no matter what their size might be.
