In order to avoid that when the cover body 60 is covered on the base body 10, the bottom of the cover body 60 seals the heat dissipation groove 161, so that air cannot circulate, a plurality of supporting pieces 70 are arranged in the heat dissipation groove 161 at intervals, when the cover body 60 is covered on the base body 10, the bottom of the cover body 60 is overlapped on the tops of the plurality of supporting pieces 70, the plurality of supporting pieces 70 divide the heat dissipation groove 161 into a plurality of third heat dissipation holes 1611, the supporting pieces 70 also play a role in dust prevention, and when external dust flows into the third heat dissipation holes 1611 along with air, part of dust can be blocked by the groove wall of the heat dissipation groove 161 or the side wall of the supporting piece 70, so that the dust cannot enter the accommodating cavity 11, thereby playing a role in dust prevention.
