The embodiment of the present application is described taking a connecting wall as an example. The first side wall 4266a and the third side wall 4266c are connected by a connecting wall, which may have an arc structure or a right-angle structure.

It should be noted that the number of the sidewalls of the fixing structure 426 is not limited to this, such as the fixing structure 426 may also include five, six or other numbers of sidewalls; alternatively, the fixed structure 426 may include only one sidewall, such as when the fixed structure 426 is a cylindrical structure, the sidewall of the fixed structure 426 is an integrally formed arcuate wall.

When the conductive terminals 442 of the driving motor 440 are received in the fixing slots 4262, the conductive terminals 442 abut against the bottom wall 4264, so that the conductive terminals 442 can be electrically connected to the circuit board 420 through the bottom wall 4264. When the conductive terminals 442 of the driving motor 440 are received in the fixing grooves 4262, a portion of the conductive terminals 442 are received in the fixing grooves 4262, and another portion of the conductive terminals 442 are located in the fixing grooves 4262.

In the embodiment of the present application, the bottom wall 4264 may be made of a conductive material, such as aluminum, copper, etc. The side wall 4266 may also be made of an electrically conductive material, for example, the bottom wall 4264 and the side wall 4266 may be integrally formed by an electrically conductive material, or the bottom wall 4264 and the side wall 4266 may be separately formed by an electrically conductive material, and then the bottom wall 4264 and the side wall 4266 are connected together.
