A ratchet wrench comprising:

• a handle including an enclosed box portion at one and, the enclosed box portion having a ratchet around its interior surface;
• a ratchet device provided in the box portion and including a bar extended downwardly, a laterally disposed recess having internal first and second walls, and an axial first bore in communication with the recess;
• a rotating disc including a shaft extended downwardly into the first bore, ad an actuation member provided on one side of the shaft;
• and
• a locking member provided in the recess and including an outer ratchet adapted to engage with the ratchet of the handle, and inner groove for receiving and being engaged with the actuation member in the recess, and third and fourth walls provided at both sides of the groove, either the third wall being adapted to contact the first wall or the fourth wall being adapted to contact the second wall when the locking member pivots to one of left and right positions in the ratchet device;
• wherein the shaft comprises two slots provided on one side opposite the actuation members and the ratchet device further comprises a receptacle provided on an interior surface of the first bore, and at spring biased detent anchored in the receptacle such that rotating the rotating disc will switch an engagement of the detent with one slot to an engagement of the detent with the other slot for positioning;
• whereby rotating the handle and the rotating disc in the same direction will cause both the locking member and the ratchet device to rotate the same;
• and rotating the rotating disc in a direction opposite to that the handle will switch a direction of force exerted upon a workpiece.
