ABSTRACT:
A manually operated, hand held pick up tool or dropped object retrieving device includes an elongated rigid tube having at one end a jaw assembly which includes two movable jaw pieces and two linkage pieces and at the opposite end a handle assembly. The jaw pieces pivot about a pivot bolt attached to the rigid tube. The movable jaw pieces are caused to approach each other in a symmetrical fashion and come into apposition when a sliding handle piece in the handle assembly is squeezed and brought toward a fixed handle in the handle assembly. A centrally placed connecting rod running longitudinally within the rigid tube couples the sliding handle to the linkage pieces of the jaw assembly. A compression spring positioned around the connecting rod within the rigid tube normally maintains the movable jaw pieces in the open position. A magnet is attached to one of the jaw pieces so as to allow retrieval of magnetic metal objects. Soft tips are placed on the ends of the jaws to improve gripping ability of the jaws and also to prevent scratching of the retrieved objects.
