A small through-hole is provided on the subplane of the inverted fan shape (e.g., in a perspective view and a top view). Also, A recessed area shaped like " " is provided inward from the bottom plane (e.g., in a bottom view). The overall appearance is completely inherited from the design style and concept of the original design (that is, the design method of directly connecting the convex arc surface formed by the large rounded corner radius of the forging to the top plane perimeter and the top edge of the arc-shaped side ring surface). Only the local surface shape adopts simple and easy-to-think variations to make its visual effect similar, so that when viewed from different places, consumers will feel that it belongs to the same series of products.
