The invention relates to the field of cables, and discloses a novel cable retracting device. The novel cable retracting device comprises a cable placement box body, the cable placement box body comprises a bottom plate, front and rear side plates and left and right side plates, a cable is placed inside the cable placement box body, a wire supplying hole is formed in the left side plate of the cable placement box body, a wire outlet hole is formed in the right side plate of the cable placement box body, a rotary through hole is formed in the bottom plate of the cable placement box body, an external thread rotary rod is inserted in the rotary through hole, the outer end of the external thread rotary rod is connected with an inner thread screw sleeve in a threaded mode, the inner thread screwsleeve is located on the lower side of the bottom plate of the cable placement box body, a handle is fixedly connected to the lower end of the external thread rotary rod, a limiting plate is fixedlyconnected to the upper end of the external thread rotary rod, the limiting plate is located in the cable placement box body, a gear is fixedly connected to the upper end of the limiting plate, and racks are connected to the left end and the right end of the gear in an engaged mode correspondingly. The cable can be effectively retracted, the required length of the cable when in use is effectively controlled, and the phenomenon of cable winding or knotting is decreased.
