发明名称 Ratchet wrench with a quick-rotation element with retaining means
摘要 A ratchet wrench with a quick-rotated element with retaining means (30) includes a shank and a ratchet wheel (12) pivotally received in one end of the shank (10). The ratchet wheel includes a polygonal hole (120) centrally and longitudinally defined therein. The polygonal hole extends through the ratchet wheel. An annular groove (122) is laterally defined in an inner periphery of the polygonal hole. A disk (20) is attached to a top of the ratchet wheel and has a through hole (21) defined therein. The through hole has a diameter smaller than that of the polygonal hole. A retainer (30) partially is received in the annular groove in the ratchet wheel, wherein the retainer is adapted to position a tool bit (50) that is partially and longitudinally received in the polygonal hole.
