Claim:
A reversible ratchet tool comprising: a housing including a chamber and a compartment formed in said housing and communicating with each other, and including two curved recesses formed therein and communicating with said compartment of said housing, and including an orifice formed therein and communicating with said compartment of said housing, a rotary member rotatably received in said chamber of said housing and including a driving stem extended outwardly therefrom, and including a plurality of teeth provided on an outer peripheral portion thereof, a cover secured to said housing for closing said chamber and said compartment of said housing, and including an opening formed therein for receiving said driving stem of said rotary member and for allowing said driving stem of said rotary member to be extended out through said opening of said cover and to be extended out of said housing, said cover including an axle extended therefrom and including three depressions formed therein and located and arranged around said axle, two pawl members received and engaged in said compartment of said housing, and each including a rounded end pivotally engaged in said curved recesses of said housing for pivotally mounting said pawl members to said housing, and each including at least one tooth formed on another end portion thereof for selectively engaging with said teeth of said rotary member, two spring members disposed in said compartment of said housing and engaged with said pawl members for biasing said pawl members to engage with said teeth of said rotary member respectively, an actuating member received in said compartment of said housing, and including a cavity formed therein for pivotally receiving said axle of said cover and for pivotally securing said actuating member in said housing, and including a projection extended from said actuating member for engaging with either of said depressions of said cover and for positioning said actuating member to said housing at said selected positions, and a hand grip rotatably engaged with said orifice of said housing and coupled to said actuating member for rotating said actuating member relative to said housing and for actuating said actuating member to selectively engage with said pawl members, and said actuating member being rotated relative to said housing and said cover with said hand grip to engage with either of said pawl members and to disengage either of said pawl members from said rotary member and for allowing said rotary member to be rotated in either direction by said housing, and both of said pawl members being biased and forced to engage with said teeth of said rotary member for allowing said rotary member to be rotated in both directions by said housing when said actuating member is centered and is not rotated relative to said housing and said cover and is not engaged with both of said pawl members.
