The creases 324 at the bends of the first blade 321a, the second blade 321b, and the third blade 321c are straight creases, and each of the straight creases coincides with the three sides of the equilateral triangle III. This arrangement is also beneficial to improving the dynamic balance of the crushing assembly 30 during rotation and the stability of the turbine.
