[0023] Furthermore, a pair of interval adjusters 9 connected to a pair of supporting rails 4 are provided on the supporting seat 3. The position of the pair of supporting rails 4 can be adjusted by the pair of interval adjusters 9, so that the pair of supporting rails 4 can adjust the position of the pair of supporting rods 5, so that the pair of supporting rods 5 are supported at the symmetrical position of the bottom of the rotor.
