ABSTRACT:
An improved driving mechanism particularly adapted for use with pick-and-place units wherein a pair of jaws are pivotally supported from a housing and movable towards and away from each other. In this manner objects may be grasped by the jaws or extension thereof and moved from one place to another and then released by reason of the aforementioned relative jaw movement. The jaws cooperatively form a socket in which a generally cylindrical bushing is mounted at opposite ends thereof in a drive member which in turn is adapted to reciprocate back and forth with respect to the housing so as to open and close the jaws. One of the jaws at the upper head portion thereof includes a laterally movable pin which acts to limit the relative movement of the jaws towards and away from each other.
