At this time, the mechanical parts are located in the center of the clamp 104, and the second motor 103 is started to drive the clamp 104 to rotate so that the mechanical parts rotate together. Since the mechanical parts are located in the center of the clamp 104, the mechanical parts only rotate along the center without moving up, down, front and back, and there is no need to position the mechanical parts again.
