Inside this guide hole ( 20 ) is arranged an outer sleeve ( 21 ) vertically movably, and this outer sleeve ( 21 ) is advanced upward by a predetermined advancing stroke by a coned disc spring ( 25 ). An inner sleeve ( 31 ) which is allowed to fit outside the plug portion ( 3 ) is wedge-engaged with the outer sleeve ( 21 ) from above, and this inner sleeve ( 31 ) is adapted to be diametrically expandable and diametrically contractible. The inner sleeve ( 31 ) is moved vertically by an output member ( 36 ).
