Pin shaft flat square cutting equipment

The utility model discloses a pin shaft flat square cutting device which comprises a base, a waste discharge port, a support, a guide rail, a feeding box, a telescopic rod, a cutting box and a waste box, and the cutting box comprises a shell, a cutting knife, a motor, a fan, a cleaning magnetic head, a connecting rod and a sliding block. A telescopic rod extends to push a pin shaft to enter a cutting box; a motor rotates to drive a cutting knife to rotate the pin shaft to cut flat and square; scrap iron generated by cutting is prevented from splashing everywhere through a shell; a fan blows the scrap iron to a waste discharge port; the sliding block slides to drive the connecting rod to enable the cleaning magnetic head to move in the shell, scrap iron which cannot be blown by the corner fan is adsorbed, the cleaning magnetic head moves to the position above the waste discharge port and is powered off to lose magnetism, and the scrap iron loses adsorption force and falls into the waste box.
