When the passive sliding frame 54 moves, it pushes the telescopic plate 57 to move along the inner wall of the groove toward the shielding net 2. When the concentrating plate 59 moves, it pushes the telescopic plate 57 to shrink. When the concentrating plate 59 moves, it drives the lower pressure rod 60 to move in the direction of approaching each other. When the lower pressure rod 60 moves, it squeezes the lower pressure frame 61 downward. When the lower pressure frame 61 is subjected to the squeezing force, it pushes the dust shield plate 4 downward and expands to both sides. Finally, the fallen dust is pushed into the inner wall of the concentrating box 5.
