In step S6, after the driven bevel gear assembly 10 is moved to the proper position, the stop washer 9 is installed on the stepped surface inside the air inlet casing 7, and then the bolt 8 is installed in the threaded hole of the air inlet casing 7 and locked to the driven bevel gear assembly 10, so as to fix the driven bevel gear assembly 10 to the air inlet casing 7. And the horizontal surface of the stop washer 9 is fitted to the screw hole of the inlet case 7 and the side surface thereof is fitted to the inner ring of the bearing 11, thereby preventing the driven bevel gear assembly 10 from being moved when the bolt 8 is locked. In addition, as shown in fig. 7, it is preferable to clamp both ends of the horizontal surface of the stopper washer 9 by the fixing pliers 1 to ensure that the stopper washer 9 itself does not move during the screwing of the bolt 8. The fixed pliers 1 adopts a scissors cross structure and points to the center of the air inlet casing 7, so that the fixed pliers 1 can stably clamp two ends of the stop gasket 9 without separation.
