With respect to the formula for the included angle α,
when the difference between the long end and the short end is larger, the deformation capacity of the deformation block 413 on the surface is stronger, the inclined angle of the flat pressing surface 419 is larger, the included angle α is smaller, and when the applied pressure value F is larger, the power for changing the state of the flat pressing block 412 is larger, the inclined angle of the flat pressing surface 419 is larger, and the included angle α is smaller.
