If the rising heights of all the support tube bodies 11 are the same, the inner side surface 102 of the hub is horizontally placed opposite to the upper side surfaces of all the support tube bodies 11; if there is at least one support tube 11 with a different elevation from the other support tubes 11, the hub may not be positioned horizontally (relative to the processing platform).
