[0036] Specifically, in the embodiment of the present application, the impeller is connected at the right flange 4, and the impeller will bring great stress to the seat body 1, so it can be connected and fixed through multiple right screw holes 8. In addition, similarly, a screw locking steel lining is provided inside the right screw hole 8, which can prevent the screw hole from being easily damaged by stress bending.

[0037] According to an embodiment of the present application, the screw hole reinforcement portion 9 is connected to the outer wall of the seat body 1 .
