According to the invention, the coordination of the anti-rope lineclamping box base and the cable tightening groove is applied, the flat cables are inserted into horizontally arranged grooves and get into a hoisting and winding box after the head and tail ends being tightened, a winding pin rod is enabled to subjected to friction and push of cable tubes to rotate so as to drive the cables to be reversely wound and output or transversely run through and output,and the cable tubes are clamped one by one through a corrugated groove clamping plate during the process so as to enable transverse lines to be interlocked and get close to the pin surface when the cable tubes are suspended, thereby achieving an effect of winding and laying the cables. The device avoids the extrusion of flanging in the suspension moving process, avoids the line slippage and deformation and also effectively protects the toughness quality of the outer shell of the cable tubes.
