Abstract: A clamp structure for an auxiliary handle attachment includes a first female member adjacent to a first channel member comprising a first channel closed side along a tool axis to receive an elongated shaft of a tool along the tool axis; a first male member arm that pivots about a body axis parallel to a tool axis; a T-handle pivot along the first male member arm to define an arm axis parallel to the tool axis a threaded fastener that extends through the T-handle pivot; and a first wing nut mounted to the threaded fastener, the first male member arm pivotable about the body axis and the first wing nut pivotable about the arm axis such that the first wing nut is engageable with the first female member to clamp the first female member against the elongated shaft to clamp the elongated shaft against the first channel closed side.

Abstract: An auxiliary handle attachment includes a first channel member comprising a first channel closed side along a tool axis to receive an elongated shaft of a tool along the tool axis; a first clamp structure attached to the first channel member to clamp the elongated shaft of the tool to the first channel closed side; a body transverse to the tool axis; and a handle that extends from the body.
