The plurality of annular parts is stacked on each other with progressively increasing radiuses. Each of the plurality of annular parts defines a plurality of second holes for receiving the workpieces, and the top cover is positioned on the annular part with a minimum radius. The plurality of connecting pieces connects the annular part with the minimum radius to the top cover and connects each two adjacent annular parts together.
