During insertion, align the positioning side plate 9 and insert it into the positioning side groove 10, and align the positioning protrusion 7 and insert it into the positioning hole 8, so that the two tube bodies 1 can be aligned and positioned with the connecting pipe sleeve 2.

[0022] As an optimization solution, Figure 2 and Figure 3As shown, a rotating ring 12 is rotatably sleeved on the outer surface of the tube body 1 on the side of the positioning side plate 9, and the rotating ring 12 is set to a ring shape that matches the tube body 1.
