Further, as a preferred embodiment of the present embodiment, not limited thereto, the upper portion of the leg 12 is gradually inclined toward the outside of the bracket body 11 in a downward-upward direction to form an inclined portion 15. The inclined part can form the back-off effect on the bowl and cup structure, so that the stability is improved.
Further, as a preferred embodiment of the present solution, and not by way of limitation, a moisture-proof gutter 16 is provided between two of said legs 12.
As shown in fig. 3-4, embodiment two: the moistureproof support 1 is provided with a bowl cup structure 3, the bowl cup 3 is a transparent bowl cup formed by injection molding of transparent insulating plastic materials, and four sub-pixel points are all located in the bowl cup structure 3.
