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).
