The invention discloses an efficient cable cutting apparatus. A frame body is fixedly connected with the upper surface of a lifting platform; an inlet operation platform and an outlet operation platform are formed in the two ends of the interior of the frame body; a pressing assembly partially extends into the interior of the frame body to move in a vertical direction; one end of a first air cylinder is fixed on the internal top wall of the frame body while the other end is connected with a cutter to drive the cutter to perform reciprocating motion in the vertical direction; a limiting plate is vertically and fixedly connected in the frame body; the adjacent side walls of the limiting plate and the cutter can be tightly attached; a limiting hole which runs through in the length direction of the frame body is formed in the limiting plate; a heating box is also arranged, between the inlet operation platform and the limiting plate, in the frame body; a reflective plate is fixedly connected below the interior of the heating box; an illumination lamp is arranged on the internal top of the heating box; and an oil coating box for performing oil coating on a cable is arranged on one side,close to a second pressing gap, of the exterior of the frame body. By virtue of the apparatus, stable cable cutting can be performed and winding can be facilitated; and the apparatus is applicable tooperators of different heights and also can realize cable oil coating.
