摘要： A method of assembling the ratcheting tool driver. A plurality of inwardly facing ratchet teeth is integral with the walls of a cylindrical retainer cavity within the hollow cylindrical retainer. A washer is mounted around the generally conduit head and is sandwiched between an external head flange and an internal retainer flange. A snap ring is positioned in the head recess in order to provide friction for the washer in conjunction with maintaining the retainer around the open end. The ratcheting tool driver includes a generally solid cylindrical switch rod has a first rod end and a second rod end with a rod recess surrounded by a hollow neck. A pawl is provided with a pawl recess. A pawl spring bias is seated in the rod recess and a bearing is disposed against the pawl spring bias and seated in the pawl recess such that when a switch button rotates the switch rod in a predetermined direction the biased bearing forces the pawl to shift within the head slot and engage one of the plurality of inwardly facing the ratchet teeth of the first cylindrical retainer cavity. The pawl is capable of being shifted in opposing directions within the formed head slot in accordance with the predetermined rotation of the switch rod. The shift of the pawl from one side and its engagement with the ratchet teeth prevents a rotation of the retainer in one direction as during application of a force simultaneously with freely providing a reverse turn of said retainer in preparation for the exertion of additional force in the prevented direction. A shifting of the pawl to the one side of the head slot and its engagement thereat with the ratchet teeth precludes a rotation of the retainer in an opposite direction while freely providing a reverse turn of the retainer.
