发明名称 Multipurpose tube wrench
摘要 An elongated cylindrical handle has a diametrical bore formed therethrough intermediate the ends thereof. A shower arm wrench body of hollow cylindrical configuration has an inner diameter equal to the diameter of the handle and an outer diameter greater than the diameter of the handle and is internally threaded and extends coaxially with a first end of the handle. A plurality of planar strips are equiangularly spaced from each other and taper downward to a second, opposite, end of the handle from an area spaced from the second end. The second end is insertable into a gas log lighter flange for tightening such flange. An axial bore formed in the handle from the second end accommodates the stem of a log lighter valve and has a plurality of equiangularly spaced grooves formed therein at the second end of the handle. A torque handle of shaft-like configuration is releasably accommodated in the diametrical bore of the handle for applying a torque thereto.
