When the rack 5486 moves, it drives the movable block 5485 to rotate. When the movable block 5485 rotates, it drives the connecting rod 5484 to rotate. When the connecting rod 5484 rotates, it drives the fixed block 544 to rotate, so that the fixed block 544 rotates in the fixed seat 545. When the fixed block 544 rotates, it drives the nozzle 543 to rotate. By adjusting the angle of the nozzle 543, the dust at different positions in the dust removal duct 4 can be comprehensively cleaned, thereby improving the cleaning efficiency.
