Abstract
A gripper includes a lead screw, a first gripping jaw and a second gripping jaw. The lead screw includes a spiral portion having at least one first spiral track and at least one second spiral track with opposite helical directions. A portion of a coverage of the first spiral track overlaps a portion of a coverage of the second spiral track along a length of the spiral portion. The first gripping jaw has a first pin extending into the first spiral track, and the second gripping jaw has a second pin extending into the second spiral track. When the spiral portion rotates, the first spiral track drives the first pin to allow a first linear movement of the first gripping jaw, and the second spiral track drives the second pin to allow a second linear movement of the second gripping jaw opposite to the first linear movement.
