Abstract:
1. A connector assembly comprising: a base adapted to rotate around a longitudinal axis, and including an attachment means for attaching a hole saw cutting device thereto, said base further including a connecting means comprising an offset pin that extends outwardly from the base, wherein said attachment means extends outwardly in the longitudinal direction and said connecting means extends inwardly in the opposite direction; a co-axial driving means adapted to rotate around said longitudinal axis; said driving means defining a passage therethrough, wherein a first surface of the base is in abutting contact with a fist surface of the driving means and wherein said offset pin extends from the base and into the driving means passage; a co-axial locking ring adapted to rotate around its longitudinal axis; wherein said locking ring defines a locking ring passage therethrough; and wherein the offset pin extends outwardly from the driving means passage and into the locking ring passage; and the locking ring is further adapted to rotate between a first and a second position relative to said driving means, and when in the first position the driving means passage and locking ring passage are aligned, and when in the second position, the driving means passage and locking ring passage are misaligned and said locking ring engages said offset pin when in said second position to prevent longitudinal relative motion between said base, driving means and said locking ring.
