The frame plates 20 clamp the upper and lower ends of the lampshade 30 at the same time. The heat dissipation bracket 10 includes a rear side wall 11 and a front side wall 12, and a connecting block is provided between the rear side wall 11 and the front side wall 12. The connecting block has a circular screw hole. Such a structure leads to a high overall cost of the structural parts. Utility Model Content
