By providing the first extension portion 125 and the second extension portion 126, the mutual restriction effect between the limiting rib 121 and the limiting member 123 can be enhanced, and the swing angle between two adjacent profile bottom shells 120 can be further reduced .

For example, the first extension 125 and the limiting rib 121 may be on the same plane, and the second extension 126 and the connecting portion 1231 may be on the same plane. Alternatively, the first extension 125 may be formed by extending the limiting rib 121 toward the flexible light board 110, and the second extension 126 may be formed by extending the connecting portion 1231 toward the flexible light board 110.
