[0026] By setting the main support plate 502 and the sub-support plate 503, the supporting structure can be segmented by using the main support plate 502 and the sub-support plate 503. And the overlapping length of the main support plate 502 and the sub-support plate 503 can be freely adjusted according to the inner diameter of the titanium cylinder 3, and riveting holes can be opened at the corresponding positions, so that the support member 5 can be mass-produced in batches without adjusting the cutting equipment back and forth due to the size change of the titanium cylinder 3.
