Abstract:
1. Clamp ( 1 ) comprising: a body ( 2 ) provided with a longitudinal axis (Z-Z) and three coplanar seats ( 21 - 23 ) for housing corresponding first, second and third jaws (G 1 -G 3 ), wherein the jaws (G 1 -G 3 ) are each alternately translatable into the respective seat ( 21 - 23 ) in two ways (X-X, X′, X″) of a direction orthogonal to the longitudinal axis (Z-Z), between a proximal position and a distal position with respect to the longitudinal axis (Z-Z) itself, and a device (A) for activating the jaws comprising an actuator ( 4 ) and a drive mechanism ( 5 - 14 ) adapted to drive a motion of the actuator ( 4 ) to the jaws (G 1 -G 3 ), wherein the drive mechanism ( 5 - 14 ) comprises a cursor ( 11 ) translatable in said body ( 2 ) integrally with the first jaw (G 1 ), in response to the actuator ( 4 ) starting, and a transmission configured to impart movement of the cursor ( 11 ) to the second jaw (G 2 ) and the third jaw (G 3 ), wherein the transmission comprises two controlling levers ( 17 , 18 ), both rotatable on a respective rotation axis parallel to the longitudinal axis (Z-Z), in response to the translatory movement of the cursor ( 11 ), the second jaw (G 2 ) and the third jaw (G 3 ) are both provided with a pin ( 24 , 25 ) extending in parallel with the longitudinal axis (Z-Z) through the body ( 2 A) of the clamp and wherein both levers ( 17 , 18 ) comprise a guide ( 172 , 182 ) in which the pin ( 24 , 25 ) is slidingly accommodated and both levers ( 17 , 18 ) are also constrained to a corresponding jaw of said second (G 2 ) and said third (G 3 ) jaws to impart a travel equivalent to the travel imparted by the cursor ( 11 ) to the first jaw (G 1 ).
