Abstract
A work supporting plunger and a control plunger are perpendicularly arranged for axial sliding movement in a work support body. The inner end of the work support plunger engages an axially inclined face on the control plunger so that axial movement of the control plunger results in movement of the work support plunger to and from supporting engagement with a workpiece. A collet in the work support body concentric with the control plunger is adapted to lock the control plunger against movement. The collet is in turn surrounded by a collet locking sleeve movable axially to lock and release the collet.
