The industrial robotcomprises a cross beam, wherein clamping hands are movably arranged at the bottom of the cross beam, magnets are fixedly arranged inside the clamping hands, bolt openings are formed in the tops of theclamping hands, an air cylinder is fixedly arranged at the bottom of the cross beam, bolts are fixedly arranged at the bottom of the air cylinder, pressing pads are fixedly arranged at the bottoms ofthe clamping hands, and air bags are fixedly arranged inside the pressing pads. When a hydraulic cylinder extends out, due to the fact that the extending end of the hydraulic cylinder is made of a magnetic isolation material, the two clamping hands are prevented from being close to each other, and when the hydraulic cylinder is retracted, the clamping hands clamp the object, and after the clamping hands grasp the object, the air bags introduce air into the air cylinder, the air cylinder pushes out the bolts, the bolts enter the bolt openings, so that the object is prevented from falling off,and the effect that the object is prevented from falling off after being clamped is achieved.
