A housing mounted to the plunger includes a cavity and rotatably supports a cam block in the cavity. The cam block has an arcuate cam face establishing respective plural axial lines of contact with the other side of the mounting portion of ones of the blades of varying thicknesses. Each of the lines of contact occupies an over-center relationship with respect to a plane perpendicular to the blade and containing the axis of rotation of the cam block.
