Screw driving extension apparatus

A screw driving extension apparatus, comprising,

• an elongate tubular housing, having a housing first end spaced from a housing second end, with the housing aligned about an axis, and a handle integrally mounted to the housing between the housing first end and the housing second end, and
• the housing first end including a first end cap, the first end cap including a first end cap bore, and a rotary shaft rotatably and reciprocatably mounted relative to the tubular housing, with the rotary shaft having a rotary shaft first end projecting through the first end cap bore, the cap having a cap annular flange in surrounding relationship relative to the first end cap bore, with the shaft having a shaft annular flange oriented adjacent the cap annular flange, and
• the shaft having a shaft second end, the shaft second end including a shaft second end socket, with the shaft second end socket including a longitudinal screw driving bit received therewithin, with the screw driving bit received within a fastener receiving cavity oriented between the shaft second end and the housing second end, and
• wherein the housing includes a fixed first bushing spaced from the shaft annular flange, and a reciprocatably mounted second annular bushing interposed between the shaft annular flange and the first bushing, and a spring, the spring positioned between the second annular bushing and the first annular bushing, with the spring arranged for compression permitting displacement of the shaft annular flange towards the first bushing.
