The invention relates to a cable arrangement, discharging and clamping device, which comprises a U-shaped clamping body, wherein the lower part of the clamping body is provided with a connecting stud, the connecting stud is arranged on a worktable, a vertical moving type push plate is horizontally arranged between two vertical columns of the U-shaped clamping body, a spring is arranged in each vertical column, the push plate is supported and floated by the springs in the vertical columns, the upper parts of the vertical columns symmetrically outwards extend to form retaining plate support arms, a retaining plate is arranged in each retaining plate support arm, is horizontally moved from interior to exterior or from exterior to interior, and is controlled by a retaining plate spring to move, each retaining plate spring is arranged in the corresponding retaining plate support arm, a spring pressure block is arranged at the outer end of each retaining plate spring, smooth transition surfaces are respectively arranged at the upper part and the lower end of one end of the inner sides of the two retaining plates, and the inner sides of the two retaining plates can be mutually touched and closed under the action of the retaining plate springs. The cable arrangement, discharging and clamping device has the advantages that the structure is simple and reasonable, the convenience in operation and use is realized, and the cable arrangement and discharging and automatic clamping are realized; after the cable is wound and bundled, only the cable needs to be lifted upwards.
