Online tensile detection device for cable production

The utility model belongs to the technical field of cables, and particularly relates to an online tensile detection device for cable production, which comprises a base, a fixed block fixedly connected to the upper surface of the base, servo electric cylinders symmetrically distributed fixedly mounted on two side surfaces of the fixed block, and guide rods symmetrically distributed fixedly connected to the two side surfaces of the fixed block. The outer surface of the guide rod is movably sleeved with a moving block. According to the online tensile detection device for cable production, the upper surface of the moving block is provided with a double-layer clamping device, the double-layer clamping device comprises a mounting block, and the lower surface of the mounting block is fixedly connected with the upper surface of the moving block, so that double-layer clamping of a cable is achieved, the clamping stability is improved, and falling off is avoided; and the cable clamping device is suitable for clamping c
