By providing the first pressing portion 84 and the second pressing portion 85, it is possible to ensure that the two stirring structures 60 do not axially move with the transmission member 70, thereby ensuring the connection reliability of the stirring structures 60 with the transmission member 70.
In this embodiment, the first pressing portion 84 may be a pressing ring, and the second pressing portion 85 may be a pressing nut.
In the present embodiment, referring to fig. 7, the power device 100 further includes a first bearing 81, a second bearing 82, and a bearing pressing portion 86. The first bearing 81 is provided in the housing 14, the second bearing 82 is provided in the cover 15, and the bearing pressing portion 86 fixes the second bearing 82 to the cover 15. One end of the transmission member 70 is engaged with the first bearing 81 and presses the first bearing 81 against the housing 14, and the other end of the transmission member 70 passes through the bearing pressing portion 86 and the second bearing 82 and protrudes to the outside of the cover portion 15 to be connected with the propeller 201. The above embodiments are only for illustrating the technical solution of the present application and not for limiting the same, and although the present application has been described in detail with reference to the above preferred embodiments, it should be understood by those skilled in the art that modifications and equivalents may be made thereto without departing from the spirit and scope of the technical solution of the present application.
