An object retrieval apparatus including a base plate having an opening disposed therethrough at a predetermined location. At least two jaws are pivotally attached to the base plate. An actuator is movably disposed through the opening in the base plate and is fixedly attached to a retention member. At least two pivot arms are pivotally attached to the retention member and the jaws. Finally, a closing means is provided for closing the jaws. In operation, the actuator is positioned such that the jaws are in open position. The actuator is then caused to contact the object to be retrieved, or a surface proximate to the object, such that the retention member and the pivot arms are moved towards the base plate, causing the jaws to pivot inward. Once the actuator is moved past a trigger point, the closing means is engaged and acts to drives the jaws inward. This inward movement causes the retention member and actuator to move toward the base plate such that a space is created between the actuator and the closed jaws for accommodating the object to be retrieved.
