1. An anchor device, comprising:
a. an anchoring mechanism including a first point for connection of a personal safety line to the anchor device and multiple jaws coupled to each other and operatively connected to the first point to expand by pivoting outwardly when tension is applied to the first point, in which the multiple jaws are pivotally connected to linkages which are pivotally connected to each other and to a central binding post, in which the central binding post connects the linkages to each other and to a connector link to provide reciprocal, vertical movement of the multiple jaws, in which an upper end of the connector link is connected to a central shaft which has extended through a central opening in the anchor device, the anchoring mechanism including an upper portion and a lower portion separated by a mounting plate and mechanically connected to each other; and
b. a cable connected to the anchoring mechanism at a second point to expand the multiple jaws when tension is applied to the cable.
