[0034] Working principle: Place the injection molded part to be inspected in the card slot 13, ensure that the raised part of the injection molded part matches the card slot, and drive the two sets of screws 6 to rotate through the double-headed driving part 5. The threads of the two sets of screws 6 are in opposite directions, so that the two sets of moving blocks 8 and the clamping plate 11 move toward the injection molded part. By presetting the double-headed driving part 5, it drives the two sets of clamping plates 11 to automatically clamp the injection molded part to be inspected, thereby improving the automation level of the inspection process, and at the same time facilitating the control of the clamping tightness, strengthening the protection of the injection molded part, and helping to reduce production costs. When the moving block 8 moves, the connecting rod 16 drives the guide block 15 to slide on the outer surface of the guide rod 14. At the same time, the guide block 15 plays a guiding role in the movement of the moving block 8, which is conducive to the stable movement of the moving block 8 along the outer surface of the screw 6.
