In the process of withdrawing the workpiece, the driving piece 82 drives the rotating shaft 8 and the avoidance frame 81 to rotate, so that the interception head 91 and the first air nozzle 41 are close to the article placing groove 252, and the power piece drives the connecting bracket 9 to rotate, so that the interception head 91 is withdrawn from the article placing groove 252; then, under the blow of the first air nozzle 41, the workpiece will enter the first docking chute 612 through the material return chute 23 and be collected into the turnaround tube 100.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
