[0054] Working principle: When using this device, place the screw to be cut in the first track on the pushing disk 11, turn on the electric push rod 111 to feed the screw from the feed port 112, and after feeding it to the predetermined position, start the cylinder 21. The cylinder 21 starts to drive the cylinder plug 22 to move, and the movement of the cylinder plug 22 drives the connecting block 23 to move. The movement of the connecting block 23 drives the two groups of extrusion rods 271 on both sides to move. The movement of the extrusion rod 271 drives the connecting sleeve 27 to move. The movement of the connecting sleeve 27 drives the spring 272 to move. The movement of the spring 272 drives the second fixed rod 273 to move. The second fixed rod 273 moves to fix the screw at the lower end. At the same time, the movement of the extrusion rod 271 drives the cutting disc 13 to move, and the fixed screw is cut to prevent the screw from moving during cutting and affecting the cutting quality.

At the same time, the L-shaped rack 24 moves, driving the third gear 242 to move, and the third gear 242 contacts the fourth rack 241 to rotate the third gear 242. The rotation of the third gear 242 drives the fan 245 to rotate, and blows air to the cutting disc 13 to prevent the cutting disc 13 from heating up due to long-term cutting and affecting the cutting quality.

[0056] At the same time, when the connecting block 23 moves, it drives the second racks 31 on both sides to move, the movement of the second racks 31 drives the second gear 32 to rotate, the rotation of the second gear 32 drives the third rack 33 to move, and the movement of the third rack 33 drives the second baffle 332 to move, pushing the iron filings generated by cutting from the upper end of the base 1 into the second groove, and collecting the iron filings generated by cutting from the collection box 15.

[0057] The iron filings generated by the cutting are pushed into the first groove at the upper end of the base 1 and enter the collection box 15 for easy collection to avoid waste. The screw is placed in the first track, fed in from the feed port 112, and sent out from the discharge port 14 to complete the cutting of the screw. The cylinder 21 is started to push the cylinder plug 22 to move. At the same time, the dust plug 252 is used to prevent the iron filings from entering the first gear 25 during cutting, affecting the rotation of the first gear 25 and avoiding damage to the device. The L-shaped rack 24 moves to drive the first gear 25 to rotate, and the first gear 25 rotates to drive the first rack 26 to move.

The first rack 26 moves to remove the first baffle 261 from the base 1 and inserts it into the shell 12 to prevent iron filings from flying out during cutting and causing harm to the staff. The first rack 26 slides inside the third groove, and the hole fixes the screw when the second fixing rod 273 is pressed down. The second baffle 332 will not squeeze the screw due to the hole when moving, avoiding the movement of the screw when the second baffle 332 moves, and the protective cover 321 makes it difficult for the iron filings generated by cutting to enter the second gear 32, avoiding the iron filings generated by cutting to affect the pushing mechanism 3.
