Handle attaching screw assembly for a fishing reel

A screw assembly for mounting a removable handle in a drive shaft provided in a body of a fishing reel wherein the drive shaft includes a central bore extending therethrough for receiving a handle shaft attached to the handle and wherein the handle shaft has a tapped, axial hole at one end opposite to the other end that is attached to the handle, the assembly comprising:

• a rotatable screw having an enlarged head portion, a central body portion, and a threaded end portion adapted to be screwed into the threaded axial bore to retain the handle shaft in the drive shaft;
• a rotatable knob having a central aperture for receiving said screw and being slidable along said screw between a fixing position wherein said knob and said screw rotate together and an operating position wherein said screw is rotatable with respect to said knob;
• a spring interposed between said knob and said screw for biasing said knob to said fixing position;
• and
• means for retaining said knob in said operating position, wherein during mounting of the handle in the drive shaft said knob is biased into said fixing position by said spring to enable rotation of said knob to rotate said screw such that said threaded end portion mates with the tapped axial bore and during operation of the reel the knob is slid to said operating position and retained thereat by said retaining means to permit rotation of said screw relative to said knob.
