ABSTRACT:
A reversible ratchet wrench comprising an elongated housing whose head portion encloses a ratchet wheel and a pawl. The orientation of the pawl determines one of two driving directions of the ratchet wheel, to which is connected a square driving member. An elongated groove containing a control device and an arcuate spring strip is provided on the upper surface of the housing. The front end of the arcuate spring strip contacts with one lateral side of the pawl, and the rear end of the spring strip is retained by the control device. The control device comprises a control switch which is controlled by the thumb or other fingers of the hand grasping the wrench, with a fixing spring assembly enabling the control switch to be fixed in place. An upper cover plate and a lower cover plate enclose the elongated housing of the ratchet wrench.
