The invention discloses a novel wiring device for electric power engineering, which belongs to the technical field of electric power engineering and comprises an outer shell, a reel is arranged in the center of the interior of the outer shell, a wheel sleeve is arranged on the periphery of the reel, a torsional spring is arranged at the bottom of the reel, a bearing is arranged on an inner ring of the torsional spring, and a winding groove is formed in the middle of the periphery of the reel. Wiring holes are formed in the two sides of the outer portion of the outer shell, guide grooves are formed in the inner sides of the wiring holes, a protruding rotary knob is fixedly arranged in the center of the top of the reel, fastening rotary knobs are arranged on the two sides of the top of the reel, fastening screw rods are fixedly arranged at the bottoms of the fastening rotary knobs, threaded sleeves are arranged on the peripheries of the bottom ends of the fastening screw rods, and pressing blocks are arranged at the bottoms of the threaded sleeves. The wire winding wheel is driven to rotate by rotating the protruding rotary knob to be matched with the torsional spring and the bearing, so that the two wires can be wound on the wire winding wheel, the wire winding wheel can be kept fastened, the stability of the wire winding wheel is greatly improved, and electrical connection between the two wires is guaranteed.
