Claim:
A woundable ratchet wrench which comprises: a driving head including a body, a rotating member, a pawl and a control structure, said body member having a first accommodation chamber with a vertical facing opening, said first accommodation chamber communicating with a second accommodation chamber, the central axial line of said rotating member being vertical extension, said rotating member rotatably mounted in the first accommodation chamber, a connecting grip horizontally stretching out from one side of said body member, a small pivot hole penetrating through said connecting grip, one end of said small pivot hole communicating with said first accommodation chamber, said rotating member having a coupling member to connect one workpiece, the outer surface of the top of the rotating member surrounded with a plurality of meshing tooth, said pawl movably and rotatably mounted in said second accommodation chamber, said pawl's front end facing said rotating member having one retaining tooth for engaging said meshing tooth, the relatively contacted position of said pawl to said rotating member being moved by means of said control structure so as to control said rotating member to make unidirectional clockwise or counterclockwise rotation; a first gearwheel whose outer surface surrounded with a plurality of first tooth, said first gearwheel and said rotating member being able to make a coaxial and synchronal rotation, said first gearwheel being inside said first accommodation chamber; a second gearwheel rotatably mounted in said small pivot hole of said body, said second gearwheel which faces one front end of said first gearwheel being surrounded with a plurality of second tooth member to engage the plurality of first tooth, a female coupling member being provided at the rear end of said second gearwheel; a woundable member with a front end connected to said second gearwheel, a rear end of said woundable member being able to be driven by an external force; a resilient tube whose interior being for accommodating said woundable member, a front end of said resilient tube being fixedly connected to said body, said rear end of said woundable member exposing outside a rear end of said resilient tube, said resilient tube being able to restore to a straight tube shape when said resilient tube is not bent by external force; and a gripping member, said gripping member includes a rigid straight bar member which accommodates said resilient tube, a front end of said straight bar member has a third joint member which couples with said connecting grip of said body, a rear end of said straight bar member has a fourth joint member which couples with a rear coupling member at the rear end of said woundable member, said fourth joint member is in a separating status from said rear coupling member when said third joint member of said straight bar member couples with said connecting grip, and said fourth joint member couples with said rear coupling member when said third joint member is separated from said connecting grip.
