By adopting the diameter of the second rivet column 33121 being greater than the diameter of the first through hole 21, the second rivet column 33121 and the electric control board 2 have a movement gap in the axial direction of the second rivet column 33121, the elastic part 32 elastically abuts against the electric control board 2, and further more conveniently offsets the vibration force through deformation. The diameter of the first positioning column 3311 is less than the diameter of the second through hole 22, thereby enabling the first positioning column 3311 to pass through the second through hole 22 to connect with the positioning part 311, and further enabling the first positioning column 3311 to better fix the electric control board 2.

[0042] As shown in Figures 3 to 5 , the positioning part 311 includes a first positioning section 3111 and a second positioning section 3112, the second positioning section 3112 is located above the first positioning section 3111, the second positioning section 3112 passes through the first through hole 21, the diameter of the first positioning section 3111 is greater than the diameter of the second positioning section 3112, and the diameter of the first positioning section 3111 is greater than the diameter of the first through hole 21, and the depth of the first through hole 21 is less than the height of the second positioning section 3112;

[0043] Alternatively, the positioning portion 311 includes a third positioning segment 3113 located below the second through hole 22, and the third positioning segment 3113 has a diameter greater than that of the second through hole 22.

By arranging the positioning portion 311 to have a stepped shape, the electric control board 2 is sleeved on the second positioning segment 3112 and located on the first positioning segment 3111. Since the first through hole 21 of the electric control board 2 has a diameter greater than that of the second positioning segment 3112 and a depth less than the height of the second positioning segment 3112, the electric control board 2 has a clearance in the circumferential direction of the second positioning segment 3112, so that the electric control board 2 has a certain degree of freedom in the circumferential direction of the second positioning segment 3112.

[0045] In this embodiment, to more conveniently fix the electric control board 2 by the first positioning column 3311, the positioning portion 311 includes a third positioning segment 3113 located below the second through hole 22, and the third positioning segment 3113 has a diameter greater than that of the second through hole 22. The diameter of the second through hole 22 is adapted to that of the first positioning column 3311.
