Abstract
An offset pin puller apparatus usable with a fluid-operated actuator tool for exerting an axial pulling force on a grooved fastener pin projecting through a workpiece. Jaws mounted within the apparatus are held against axial motion while an associated collet moves axially to cam the jaws into clamped engagement with the fastener pin. The jaws are released from the fastener pin by abutment of a jaw release assembly with an inner wall of the apparatus. Such abutment effects an axial and radial separation of the jaws from the collet during a return stroke of the actuation tool.
