A ratchet wrench with a quick-rotated element which has a blocking function, includes a shank and a ratchet wheel pivotally received in one end of the shank. The ratchet wheel includes a polygonal hole centrally and longitudinally defined therein. The polygonal hole extends through the ratchet wheel. An annular groove is laterally defined in an inner periphery of the polygonal hole. A disk is attached to a top of the ratchet wheel and has a through hole defined therein. The through hole has a diameter smaller than that of the polygonal hole. A retainer partially is received in the annular groove in the ratchet wheel, wherein the retainer is adapted to position a tool bit that is partially and longitudinally received in the polygonal hole.
