Taper lock apparatus

摘要

A taper lock apparatus, including a screw defining a longitudinal axis and having a tapered end at one end thereof, the tapered end including a threaded bore extending partially along the longitudinal axis; a compression fitting having expansions, the fitting defining an internal space having an internal taper, the internal space configured to mate at least partially with the tapered end of the screw; and a retaining screw configured to mate with the threaded bore, wherein tightening of the retaining screw into the bore engages the taper end of the screw with the internal taper of the fitting forcing the expansions radially outward.

1. A taper lock apparatus, comprising:
a work screw having a tapered end; a compression fitting having an expandable end and a fixed end and including at least two slits positioned substantially parallel to a longitudinal axis of the fitting and extending from the expandable end toward the fixed end, the fitting defining an internal space having an internal taper extending at least partially along the longitudinal axis from the fixed end to the expandable end; and a retaining screw, wherein the tapered end of the work screw defines a threaded bore extending partially along the longitudinal axis, the threaded bore configured to mate with the retaining screw, and the tapered end of the work screw engages with the internal taper of the fitting to expand the expandable end of the fitting.
