After that, the support 2e is moved back and matched with the end of the rotating shaft 2c.

[0025] The support 3 is located outside the box E and is fixed with the box E. The support 3 is composed of a horizontal mounting plate and a vertical mounting plate. One end of the horizontal mounting plate is fixed with the box E, and one end of the vertical mounting plate is fixed with the other end of the horizontal mounting plate.
