By the elongated hole 50 along the virtual arc of the center and the tightening screw 51 inserted through the elongated hole 50, the discharge cylinder 30 is connected so as to be vertically tiltable, and the connecting shaft S is formed as the tightening screw. By forming the fitting hole 7 into which the connecting shaft S is fitted into a long hole along a virtual arc centered on the tightening screw 51 described above, the tilt angle α can be adjusted by a pair of upper and lower long holes. Since the length of the oblong hole that regulates the range of the inclination angle α can be shortened, the adjustment range of the inclination angle can be made large, so that the cut object from this oblong hole can be processed. It becomes possible to effectively prevent scattering and penetration of the cut processing object into the long hole.
