Abstract
A rapid securement device for a tool or workpiece holder, comprising an elongated stem, and an elongated axle extending through the stem for axial movement relative to the stem. The stem has a head thereon, the head having a hole therethrough that registers with holes through the stem. A peg for holding a tool or a workpiece holder extends through the holes and has a flat surface that engages with a flat surface on the head. A spring urges the axle in a direction relative to the stem to engage the flat surfaces forcibly together thereby releasably to retain the peg in the holes.
