[0020] Working principle: when the cutting device is performing a cutting operation, the steel is placed on the top of the working box 1 through the feed port opened on the right side of the protective box 301, and the motor 4 is started. The motor 4 drives the threaded rod 501 to rotate, and the threaded rod 501 drives the slider 502 to move relatively, and the slider 502 drives the connecting rod 503 to move relatively until it contacts the surface of the steel and limits it to the left and right. The slider 502 moves relatively to make the support rod 505 press down, and the support rod 505 drives the transmission plate 601 to move downward, and the transmission plate 601 drives the fixed rod 602 to move downward, and the fixed rod 602 drives the mounting plate 603 to move downward. At this time, the mounting plate 603 drives the pressing block 604 to press down, thereby limiting the upper and lower limits of the steel. The cutting quality and precision are improved. When the steel is firmly fixed, the operator holds the handle of the cutting machine body 2 and presses down to cut. At this time, the downwardly moving surface of the handle collides with the inner wall of the protection box 301, causing the protection box 301 to move downward until it contacts the top of the working box 1, thereby completely isolating the sparks and metal generated during the cutting process, thereby improving the safety rate. The protection box 301 moves downward, driving the trigger arc block 701 downward, so that the trigger arc block 701 drives the pressure rod 702 to press down during the pressing process, and the pressure rod 702 drives the waste basin 705 to tilt downward, and discharges the metal scraps accumulated in the waste basin 705, effectively preventing metal scraps and dirt from accumulating inside the equipment and increasing the service life of the equipment.
