The inner member is telescoped slidably into the outer member, and has a first end extending axially beyond said outer member. A nut is fixed relative to the inner member. A rotatable screw is axially fixed relative to the outer member and threadably engaging the nut, wherein rotation of the screw axially drives the nut to axially move the inner member relative to the outer member.
