The prismatic protrusion comprises a first inclined surface and a second inclined surface. One side of the first inclined surface is adjacent to the first end surface, one side of the second inclined surface is adjacent to the second end surface, and the other side of the second inclined surface is adjacent to the other side of the first inclined surface. The first inclined surface and the first end surface form an acute angle theta 1, the second inclined surface and the first end surface form an acute angle theta 2, and the theta 1 and the theta 2 satisfy the following relation: theta 2 is larger than theta 1, and theta 1 plus theta 2 is larger than or equal to 60 degrees and smaller than or equal to 80 degrees. Through setting up first beveler second inclined plane aims at improving the light scattering that keeps off the ring structure and leads to, and the fashioned technology degree of difficulty of ring is kept off in the control simultaneously.
