[0045] In some embodiments,

[0046] The materials of the first rib 2 and the second rib 3 are both ABS material or PP material. When the materials of the first rib 2 and the second rib 3 are both ABS material, the material thickness B of the second rib 3 and the material thickness A of the first rib 2 satisfy the relationship B=0.5~0.6A. When the materials of the first rib 2 and the second rib 3 are PP material, the material thickness B of the second rib 3 and the material thickness A of the first rib 2 satisfy the relationship B=(0.4~0.5)A.
