Abstract

Disclosed is a reciprocating pneumatic tool that includes a retainer mechanism for preventing the piston from freely exiting the barrel of the tool when the retaining sleeve and workpiece are removed. The retainer mechanism does not interfere with the functional operation of the tool when the workpiece and sleeve are attached to the tool. The retainer mechanism is mounted distally around the butt of the workpiece such that no contact occurs with the retainer mechanism or the piston.
