Claim 11:
12. The apparatus as claimed in claim 1, wherein the twisting mechanism comprises:
a base plate connected to a hollow rotation shaft for rotation by the twisting mechanism motor; and a hub that is linearly movable relative to the base plate in response to linear movement of a linear actuator shaft that extends through the hollow rotation shaft and the base plate, wherein the linkage mechanism is connected to the base plate and the hub and configured to convert relative vertical linear movement between the base plate and the hub into radial opening and closing movement of the plurality of jaws, and
wherein the plurality of jaws extend from a plurality of connecting rods pivotally connected to the base plate, and
wherein the linkage mechanism comprises a plurality of cam slots in the hub and a plurality of cam followers fixed to the connecting rods and extending into the plurality of cam slots to cause the respective connecting rods to pivot and thereby open and close the plurality of jaws in response to the linear movement of the hub relative to the base plate.
