[0002] With the development of the times, industrial production technology is also developing rapidly, and automatic equipment is also applied in industrial production more and more, and workpieces are usually transported by conveying flow lines. Since the length of a single flow line is limited, in order to ensure that the workpiece can be smoothly moved to the designated position, the first and last ends of multiple flow lines are usually connected in a butt joint manner. However, since the flow lines are connected in a butt joint manner, they cannot be completely fitted, so there is usually a gap at the butt joint. When the workpiece needs to be moved from the current conveying flow line to the subsequent flow line, since there is a gap at the butt joint, the conveying flow line and the subsequent flow line may not be able to provide power for the workpiece when the workpiece moves to the butt joint. At this time, the workpiece is difficult to enter the subsequent flow line, and is easy to be stuck in the gap.
