The connecting rod 2 moves downward to drive the L-shaped rod 21 to move downward. The L-shaped rod 21 moves downward to drive the arc-shaped push plate 22 to move downward. The arc-shaped push plate 22 moves downward to push the slide bar 31 to move. The slide bar 31 moves to drive the rack 3 to slide. The rack 3 slides to drive the third gear 73 to rotate. The third gear 73 rotates. 3 rotates to drive the second rotating shaft 7 to rotate, the second rotating shaft 7 rotates through the first circular groove 42 to drive the first side rod 41 to rotate, the first side rod 41 rotates to drive the first protective cover 4 to rotate, when the second rotating shaft 7 rotates, it will drive the second gear 72 to rotate, the second gear 72 rotates to drive the first gear 61 to rotate, the first gear 61 rotates to drive the first rotating shaft 6 to rotate, the first rotating shaft 6 rotates through the second circular groove 51 to drive the second side rod 52 to rotate, the second side rod 52 rotates to drive the second protective cover 5 to rotate, that is, the first protective cover 4 and the second protective cover 5 will rotate close to each other, in the cutting assembly 14 protects the cutting area when cutting to prevent the cutting debris from splashing. After the cutting is completed, the cylinder 13 drives the cutting assembly 14 to reset and drives the connecting rod 2 to reset. The user rotates to open the first protective cover 4 and the second protective cover 5 to take the cut workpiece.
