Drawing cutting device

The utility model belongs to the technical field of drawing cutting for industrial design, and particularly relates to a drawing cutting device which comprises a base, the left side of the upper surface of the base is fixedly connected with the lower surface of a lifting frame, a lifting assembly is arranged in the lifting frame, and the right side face of the lifting frame is in sliding connection with the left side face of a moving frame. A moving assembly is arranged in the moving frame, a stepping motor b drives a mounting frame and a cutter to move rightwards, then the position, needing to be cut, of a drawing is adjusted, a stepping motor a drives the moving frame and the cutter to move downwards, then the drawing is cut, and in the cutting process, the length of a fixing plate is larger than that of the cutter, so that the cutting efficiency is improved. Therefore, the fixing plates firstly make contact with the cutter, then the fixing plates on the left side face and the right side face of the mountin
