Cable pay-off device with positioning and cutting-off structure

The utility model discloses a cable pay-off device with a positioning and cutting-off structure, which comprises a base, the inner side and the outer side of the base are fixedly connected with fixing plates, the fixing plates are rotatably connected with connecting rods, the connecting rods are fixedly connected with flanges, the base is provided with a cutting mechanism, and the top end of the base is fixedly connected with two connecting plates. The cable pay-off device has the advantages that the upward sliding bearing enables the driven roller to move upwards, so that a cable is squeezed between the driving roller and the driven roller, the crank is rotated by hand to enable the driving roller to rotate, and the friction between the driving roller and the cable enables a wire harness cable to move for pay-off. The length where the cable is released when the driving roller rotates by one circle can be obtained according to the perimeter of the driving roller, the number of turns of rotation of the crank a
