10. The method of claim 9, wherein the method further comprises: in the step S2, before the upper die (4) is disassembled, the upper base (2) needs to be lowered down, so that the upper die (4) is placed on the lower die (3) or the bearing platform, and then the hexagonal solid nut (204) is rotated.
