Stator fixing structure

The invention provides a stator fixing structure. The stator fixing structure comprises a middle pipe and a fixing assembly, wherein the middle pipe has an outer surface which is sleeved with a stator assembly; the fixing assembly is arranged on the outer surface of the middle pipe in a sleeving manner, and has a body; the body has a contact surface and an occlusion unit; the occlusion unit extends from the body to a center of the body in a convex manner; the occlusion unit has a free end used for propping against the outer surface of the middle pipe; and the contact surface is in contact with the stator assembly in an axial direction to limit the axial displacement of the stator assembly so as to further fix the stator assembly axially. 本发明提供种定子固定结构，包括：中管及固定组件。所述中管具有外表面套设定子组。所述固定组件套设在所述中管的外表面，具有本体，所述本体具有接触面及咬合单元，所述咬合单元从本体朝所述本体的中心凸伸，且所述咬合单元有自由端用以抵接所述中管的外表面，所述接触面在轴向接触所述定子组，以限制所述定子组的轴向位移，进而在轴向固定所述定子组。
