[0003] In the daily processing of mechanical parts, it is necessary to roughly cut the part blanks to facilitate the subsequent processing process. During the cutting process, due to the high-speed rotation of the cutting wheel, the cutting wheel is likely to cause the part to move and deviate when it contacts the part, resulting in an uneven cut surface. When the parts are fixed, they are usually fixed by manually twisting the screw or bolt to drive the clamp. When the number of clamps is large, the operation of the staff is cumbersome and it is not convenient to clamp and fix. Utility Model Content
