When the horizontally movable shell 103 and the vertically movable shell 108 are closed, the connecting air pipe 504 moves downward and is connected to the curved pipe 502. By setting a sealing ring at the lower end of the connecting air pipe 504, the air tightness of the connecting air pipe 504 and the curved pipe 502 can be increased.
