A belt is laid on the deflecting roller 5. Spherical plain bearings 19 are respectively connected inside the fixed bearing seat 16 and the sliding deviation adjustment bearing seat 10. The fixed bearing seat 16 and the sliding deviation adjustment bearing seat 10 are linked to rotate the deflecting roller 5 for deviation adjustment.
