A digital image-capturing device includes an outer lens barrel, an image sensor disposed in the outer lens barrel, an inner lens barrel mounted in the outer lens barrel, and a lens module mounted in the inner lens barrel. The outer lens barrel has a barrel coupling segment formed with an internal screw thread, and a barrel guiding segment. The inner lens barrel has a barrel engaging segment formed with an external screw thread to engage threadedly the internal screw thread of the barrel coupling segment, and a barrel sliding segment in sliding and rotatable contact with the barrel guiding segment. When the inner lens barrel is inserted into the outer lens barrel, the barrel guiding segment can guide the barrel sliding segment to prevent the inner lens barrel from wobbling and to maintain optical axis alignment, thereby ensuring image-capturing quality of the device.

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.
