The invention discloses an anti-pinching carrying mechanical arm which comprises a mounting arm. A cross beam is arranged at one end of the mounting arm and is perpendicular to the mounting arm, the mounting arm is located at the midpoint of the cross beam, and clamping rails are arranged on the two sides of the side, away from the mounting arm, of the cross beam. A fixed clamping arm is arranged at the position, at one ends of the clamping rails, of the cross beam, an air cylinder is mounted at the end, close to the fixed clamping arm, of the cross beam, an adjusting clamping arm is movably mounted at the ends, away from the fixed clamping arm, of the clamping rails, and a piston rod of the air cylinder is fixedly connected with the adjusting clamping arm. The air cylinder is adopted as a clamping force source, clamping force is stable, controllable sensitivity is high, clamping force can be conveniently and fast adjusted, the adjusting clamping arm can move on the clamping rails, and the anti-pinching carrying mechanical arm can adapt to carrying out objects of different sizes. An anti-pinching elastic column and an inner clamping plate achieve a certain buffering function during object clamping, and the situation that due to the fact that the clamping arm clamping force is too large, the objects are pinched is avoided.
