By providing the opening portion 1213 on the first wire regulating unit 121 when the wire is moved upward due to an external force or the like, the wire moved upward can be accommodated in the opening portion 1213, so that the portion of the wire located on the first end surface 111 can be prevented from being lifted from the first end surface 111, as compared with the case where the opening portion 1213 is not provided.

In at least one embodiment, the opening portion may be provided in the second wire regulating unit 122, whereby the possibility that the wire is lifted from the first end surface 111 can be further reduced.

In at least one embodiment, the recessed shape of the opening portion 1213 may be any shape, for example, the recessed shape of the opening portion 1213 may be a quadrangle or a semi-arc shape. Thus, the manufacturing process of the fan can be simplified, and a large space for accommodating the lead can be provided.

In at least one embodiment, the size of the opening portion 1213 (the width of the opening in the left-right direction in fig. 3) may be the width of the wire (the width of the wire in the left-right direction accommodated within the opening) or more, whereby the wire can be reliably accommodated.

Fig. 3 is a schematic view of the fan of embodiment 1 of the present invention, showing the fan as viewed from the side direction. In at least one embodiment, as shown in fig. 3, the first wire regulating unit 121 and the second wire regulating unit 122 are arranged in the up-down direction.

In at least one embodiment, the second fixing portion 1221 and the first arm portion 1212 may at least partially overlap in the up-down direction, in other words, a part of a projection of the second fixing portion 1221 in the up-down direction falls on a projection of the first arm portion 1212 in the up-down direction, or all of the projections of the second fixing portion 1221 in the up-down direction fall on a projection of the first arm portion 1212 in the up-down direction.

By providing the second fixing portion 1221, the wire can be blocked from slipping out of the first inlet 1214 of the first wire regulating unit 121 in the first direction, and thus, the wire can be prevented from falling out of the regulating position.

In at least one embodiment, the second wire regulating unit 122 may include only the second fixing part 1221, but the present application is not limited thereto, and the second wire regulating unit 122 may further include a second arm part 1222 as shown in fig. 2. One end G of the second arm 1222 extends from the other end F of the second fixing portion 1221 in the second direction, and the other end of the second arm 1222 is suspended to form a second free end H.

In at least one embodiment, the second wire regulation unit 122 can further include a second inlet (not shown) located between the second free end H and the sidewall 112. The second inlet is for the wire to enter a second space enclosed by the second wire regulating unit 122 and the side wall 112.

Thus, the wire can be more reliably regulated in the first space and the second space, and the wire can be prevented from falling off from the regulation position.

Fig. 6 is a cross-sectional view taken along a broken line LL' in fig. 5 in embodiment 1 of the present invention. In at least one embodiment, a portion between the end C and the first free end D of the first arm 1212 (e.g., a middle portion of the first arm 1212) is spaced a first predetermined distance D1 from the sidewall 112, and a portion between the end G and the second free end H of the second arm 1222 (e.g., a middle portion of the second arm 1222) is spaced a second predetermined distance D2 from the sidewall 112, wherein the second predetermined distance D2 is less than or equal to the first predetermined distance D1.

Accordingly, the distance between the second arm portion 1222 and the side wall is smaller than the distance between the first arm portion 1212 and the side wall 112, and the wire can be further restricted by the second wire regulating means 122, so that the wire can be prevented from falling off from the regulating position.

In at least one embodiment, when the outer diameter of the wire is greater than the second predetermined distance d2, the second wire regulating unit 122 cannot regulate the wire, and at this time, the wire can be regulated using only the first wire regulating unit 121; when the outer diameter of the wire is smaller than the second predetermined distance d2, both the wire regulating units can regulate the wire, and at this time, the wire can be regulated by using both the first wire regulating unit 121 and the second wire regulating unit 122.

In at least one embodiment, the first free end D of the first wire regulating unit 121 is spaced apart from the side wall 112 by a first distance D3, a portion between the one end C of the first arm portion 1212 and the first free end D is spaced apart from the side wall 112 by a first predetermined distance D1, and the first distance D3 is smaller than the first predetermined distance D1, in other words, the width of the first inlet 1214 is smaller than the distance between the middle portion of the first arm portion 1212 and the side wall 112.

In at least one embodiment, the second free end H of the second wire regulating unit 122 is spaced apart from the side wall 112 by a second distance d4, a portion between the end G and the second free end H of the second arm 1222 is spaced apart from the side wall 112 by a second predetermined distance d2, and the second distance d4 is less than the second predetermined distance d2, in other words, the width of the second entrance is less than the distance between the middle portion of the second arm 1222 and the side wall 112.

In at least one embodiment, the first distance d3 is less than the first predetermined distance d1 and the second distance d4 is less than the second predetermined distance d 2.

The wire can be further prevented from escaping from the first space or the second space by making the first distance d3 smaller than the first predetermined distance d1 and/or making the second distance d4 smaller than the second predetermined distance d 2.
