Novel clamping jaw mechanism

The utility model discloses a novel clamping jaw mechanism which comprises a first jaw single body, a second jaw single body and a driving source. The first claw single body and the second claw single body are both connected to the driving source, the driving source drives the two claw single bodies to synchronously move in the opposite direction or the reverse direction, and a plurality of first clamping grooves used for clamping different materials are formed in the free end of the first claw single body. The free end of the second claw single body is provided with a plurality of second clamping grooves corresponding to the first clamping grooves in a one-to-one mode, the driving source drives the first claw single body and the second claw single body to synchronously move in the opposite directions, and corresponding materials are clamped through the first clamping grooves and the second clamping grooves which correspond to each other. The clamping jaw mechanism is provided with a plurality of clamping gro
