[0032] Reference Figure 5 , Figure 6 The second base 11 has a circular hole. The upper surface of the first base 10 has a rotating ring 12 that protrudes upward and passes through the circular hole. The upper end of the rotating ring 12 extends outward to form an annular plate. The annular plate abuts against the upper surface of the second base 11. A pointer is engraved on the upper surface of the annular plate. The outer diameter of the annular plate is smaller than the width of the second base 11.
