Abstract (en)
A ratchet wrench with clamping and blocking functions includes a shank having an enlarged head formed on one end thereof. A through hole is defined in the enlarged head and a ratchet wheel is pivotally received in the through hole. A first annular groove is defined in an inner periphery of the through hole. The ratchet wheel has a polygonal hole longitudinally defined therein. The polygonal hole extends through the ratchet wheel. A second annular groove and a second annular groove are respectively defined in an inner periphery of the polygonal hole. A stopper is partially received in the second annular groove and adapted to prevent a tool bit overly extending through the ratchet wheel and a retainer is partially received in the third annular groove and adapted to position the tool bit in the ratchet wheel.
