The two cam plates being associated with a shaft for driving linear movement, the jaws being coupled to the central stationary part and the two cam plates (4). Thus, during a forward movement of the cam plates, said plates cause a linear movement away from one jaw respective to the other, during a backward movement thereof, said cam plates (4) cause a linear movement for moving one of the jaws (3) closer to the other. ## Claims ### Claim 1 A tool comprising a pair of jaws interacting with one another by means of actuating means, characterized in that said actuating means comprise a central stationary part and two cam plates arranged such that said plates are facing both sides of the central stationary part, the cam plates being slidable on said central stationary part, the two cam plates being associated with a shaft for driving linear movement, and wherein the jaws are coupled to the central stationary part and the two cam plates, such that during a forward movement of the cam plates, said plates cause a linear movement away from one jaw respective to the other, during a backward movement thereof, said cam plates cause a linear movement for moving one of the jaws closer to the other, wherein each of the cam plates has a pair of linear upper slots and a pair of linear lower slots that converge respectively at a point near a central longitudinal axis of the cam plates, and wherein protuberances projecting from each of the jaws are slidable in the upper and lower slots. ### Claim 2 (depends on 1) The tool, according to claim 1, wherein the two cam plates are joined together by means of an intermediate piece coupled to a linear driving shaft, said intermediate piece being movable through guiding means disposed on the central stationary part. ### Claim 3 (depends on 2) The tool, according to claim 2, wherein the intermediate piece and the two cam plates have additional fixing means. ### Claim 4 (depends on 3) The tool, according to claim 3, wherein such fixing means comprise through holes disposed in the intermediate piece and the two cam plates in which a pin or screw element is inserted. ### Claim 5 (depends on 1) The tool, according to claim 1, wherein the tool has elastic means disposed between the two jaws. ### Claim 6 (depends on 5) The tool, according to claim 5, wherein the elastic means comprise at least one helical spring housed in the central stationary part. ### Claim 7 (depends on 1) A grip device, for the precision handling of small objects, wherein the grip device comprises the tool, according to claim 1, wherein said tool is actuated by actuating means. ### Claim 8 (depends on 7) The grip device, according to claim 7, wherein the actuating means include electrically motorized means. ### Claim 9 (depends on 7) The grip device, according to claim 7, wherein the grip device includes a user interface connected to the actuating means. ### Claim 10 (depends on 9) The grip device, according to claim 9, wherein the actuating means include a printed circuit board connected to the user interface. ### Claim 11 (depends on 7) The grip device, according to claim 7, wherein the actuating means include a rotating shaft solidly coupled to the central stationary part. ### Claim 12 (depends on 11) The grip device, according to claim 11, wherein the rotating shaft is internally hollow, the shaft for driving linear movement being concentrically arranged inside the rotating shaft. ### Claim 13 (depends on 7) The grip device, according to claim 7, the tool includes removable blocking means for maintaining the central stationary part joined to a rotating shaft. ### Claim 14 (depends on 13) The grip device, according to claim 13, wherein the removable blocking means comprise a pin fitted on one end with a grip section, insertable in a circumferentially slotted section present in the central stationary part of the actuating means and a tightening rotating wheel. ### Claim 15 (depends on 7) The grip device, according to claim 7, wherein rotary movement of a rotating shaft of the actuating means is transmitted by a gear assembly formed by two cogwheels that engage with each other, wherein each cogwheel is associated with an independent actuator. ### Claim 16 (depends on 7) The grip device, according to claim 7, wherein the grip device includes an outer housing wherein the actuating means and, at least partially, the tool, are housed. ### Claim 17 A tool comprising a pair of jaws interacting with one another by means of actuating means, characterized in that said actuating means comprise a central stationary part and two cam plates arranged such that said plates are facing both sides of the central stationary part, the cam plates being slidable on said central stationary part, the two cam plates being associated with a shaft for driving linear movement and wherein the jaws are coupled to the central stationary part and the two cam plates, such that during a forward movement of the cam plates, said plates cause a linear movement away from one jaw respective to the other, during a backward movement thereof, said cam plates cause a linear movement for moving one of the jaws closer to the other, and wherein the central stationary part comprises a substantially U-shaped body that includes side flaps, each having a pair of upper grooves and a pair of lower grooves in which the protuberances that project from each of the jaws are slidable, and wherein the upper and lower grooves extend from a central part of the side flaps in the direction of upper and lower rims, respectively. ### Claim 18 A tool comprising a pair of laws interacting with one another by means of actuating means, characterized in that said actuating means comprise a central stationary part and two cam plates arranged such that said plates are facing both sides of the central stationary part, the cam plates being slidable on said central stationary part, the two cam plates being associated with a shaft for driving linear movement and wherein the laws are coupled to the central stationary part and the two cam plates, such that during a forward movement of the cam plates, said plates cause a linear movement away from one jaw respective to the other, during a backward movement thereof, said cam plates cause a linear movement for moving one of the jaws closer to the other, wherein the two cam plates are joined together by means of an intermediate piece coupled to a linear driving shaft, said intermediate piece being movable through guiding means disposed on the central stationary part, and wherein the guiding means comprise a window disposed on each of side flaps of a substantially U-shaped body.
