摘要： A wrench body pivotally connected to an end of a reciprocating power source, a tool head assembly attached to the opposite end of the reciprocating power source, which would include a tool head, having an aperture for the work piece, tracking arm attached to the tool head and for being matingly slideable into a surface of the wrench body; a retainer ring having at least two retainer grooves; at least two roller drive pins positioned within each of the retainer grooves, and biased away from the retainer rim by a leaf spring inserted between the wall of the rim and each drive pin; a ratcheting gear operative attached to the tool body and positioned in the aperture for connecting the work piece, the ratcheting gear having a plurality of axially aligned and beveled channels along the perimeter of the gear so that one of the drive pins are received into at least one of the channels, in order to achieve the ratcheting function, and through a movement of 15.degree., the second ratcheting pin is positioned within a channel, for reestablishing the ratcheting motion, while the first pin resumes its position within the retainer groove. A second embodiment would provide a plurality of rollers to particularly define the tracking arm, and a pair of springs to work with the drive pins.
