[0045] When the conveying roller rotates for a long time, it may deviate. At this time, the cylinder 5 is started to move up and down through the internal piston 7, so that the first connecting shaft 8 drives the connecting rod 12 to push upward through the connecting assembly 10. At this time, the end of the connecting rod 12 connected to the conveying roller will be driven to move slightly downward, so that the deviated conveying pipe can be corrected;

[0046] Secondly, when the connecting rod 12 is about to be displaced, the cylinder 5 will be slightly pulled by the pulling force of the connecting rod 12, so that the cylinder 5 is slightly rotated by the rotation of the first connecting block 3 and the first fixed shaft 4, thereby ensuring the pulling effect of the overall displacement of the connecting rod 12;
