Patent ID: 8522830

Claim:
A device comprising: at least a first pair of jaws; an operating handle connected to the first pair jaws, which closes the first pair of jaws when rotated in a first direction of rotation of the operating handle, and opens the first pair of jaws when rotated in a second direction of rotation of the operating handle; a second pair of jaws; a lever connected to the second pair of jaws, which remains stationary when rotated in a first direction of rotation of the operating handle, and closes the second pair of jaws when rotated in a second direction of rotation of the operating handle; a collapsible linkage linking the lever to the operating handle, the collapsible linkage having a joint that allows the linkage to collapse and the operating handle to be rotated in the first direction of rotation without moving the second pair of jaws from the open position as a result of the collapsible linkage being collapsed; and at least one mechanical bias, the collapsible linkage being mechanically biased via the at least one mechanical bias to cause the second pair of jaws to close when the operating handle is rotated in the second direction from a configuration in which the first pair of jaws is closed and the second pair of jaws is open.
