Hand tool with external jam nut and internal ramped cylindrical compression wedge

A hand tool comprising:

• a longitudinally extensive handle;
• a first coupler half selectively secured to and terminating said handle;
• a second coupler half selectively removable from said first coupler half and having a mounting stop,
• a threaded tube, a central axis of said threaded tube that defines a second coupler half longitudinal axis, and wherein said threaded tube comprises threads helically wound around said second coupler half longitudinal axis, and
• an anti-rotation member displaced radially from said second coupler half longitudinal axis;
• an implement affixing knob having a knob body, an outer surface configured to be manually grasped and rotated, and a threaded bore configured to selectively thread on to said threaded tube;
• and
• a fastener passing through a hollow longitudinal internal passage within said threaded tube from said second coupler half to said first coupler half, said fastener selectively securing said first and second coupler halves together;
• wherein said fastener further comprises a bolt;
• and
• wherein said first coupler half is located at least in part within said longitudinally extensive handle and comprises a threaded ramped wedge configured to expand radially when said bolt is rotated in a first direction about said second coupler half longitudinal axis and configured to contract radially when said bolt is rotated in a second direction opposite to said first direction about said second coupler half longitudinal axis.
