A clamping apparatus for hammering a hardened nail comprises a nail clamping device adapted to clamp a hardened nail, a ring sleeve receiving the clamping device at it's inner surface and an elongated handle connected at the outer surface of the ring sleeve. The clamping device is a truncated cone made of an elastic material and having an axial through center hole and a longitudinal through groove from the axial hole radially outwards to an outer surface of the cone. The ring sleeve has a tappered inner surface to taperingly engage with the truncated cone. The handle has predetermined length and two ends for connecting different sizes of ring sleeves.
