The invention relates to a cable, in particular to a heat-resistant, fire-resistant and environment-friendly low-voltage cable with high tensile strength. The distance between two movable stop piecescan be adjusted, so that when the number of cables needing to be wound is small, the two movable stop pieces can get close to each other, so that the cable can be wound on a shaft rod more easily; after the cable is wound, a cable anti-falling frame can press the cable, and the cable anti-falling frame can limit the rotation of the shaft rod to prevent the cable from loosening; a guider can guidethe winding position of the cable when the cable is wound. The two movable blocking pieces are arranged in the front-back direction and matched with the cable base through threads, and a reel is rotationally connected to the upper end of the cable base, wherein the upper ends of the two movable blocking pieces are slidably connected with the reel. The cable anti-disengaging frame is fixedly connected to the right end of the cable base, and the guider is slidably connected to the left end of the cable base.
