The main body 100 includes a shell 110 and a fan 112 inside the shell 110.
The shell 110 includes a first wall 114 and a second wall 116 opposite and parallel to the first wall 114 to sandwich the fan 112 therebetween. An outlet 120 is defined in the shell 110 between the first and second walls 114 and 116, at a side of the shell 110. A first gap 130 is defined in the shell 110 beside and communicating with the outlet 120. A column-shaped connecting portion 140 is set on the shell 110 at an end of the first gap 130 away from the outlet 120. A slot 142 is axially defined in the connecting portion 140.
Two arc-shaped sliding grooves 150 are formed on inner surfaces of the first wall 114 and the second wall 116, respectively. A plurality of locating holes 152 is defined in the two sliding grooves 150.
The cover 200 includes two parallel side plates 210 and a middle plate 220 perpendicularly connected between corresponding edges 213 of the two side plates 210. The shape of each side plate 210 is nearly a triangle. The edges 213 of the side plates 210 connected to the middle plate 220 are arced. The distance between the two side plates 210 is a little less than the distance between the first wall 114 and the second wall 116 of the shell 110, to make sure that the cover 200 can be accommodated in the first gap 130 of the shell 110.
A plurality of positioning pins 230 is set on the outer surfaces of the two side plates 210, adjacent to great ends of the side plates 210.
A second gap 240 is defined at an end of the middle plate 220 away from the plurality of positioning pins 230. Two connecting axes 250 extend from the middle plate 220 towards the second gap 240.
