The pushing device pushes the insertion rod 4 inward, causing the sliding plate 7 to slide on the surface of the sliding strip 8. The sliding circular plate 5 gradually approaches the end of the tube 1 until the first side 501 abuts against the second side 102. The first side 501 and the second side 102 are welded together, completing the pin connection between the pin component and the tube 1.
