There is a rotating shaft; the rotating shaft is opposite to the roller slot, the rotating shaft is covered with a roller, and the roller is inserted into the roller slot.

[0015] The first cleaning disk and the second cleaning disk are provided with four rollers, and the legs are located on the outer disk surface of the first cleaning disk and the second cleaning disk.

[0016] The elastic member is disposed between the roller and the cleaning disk to enable the roller to move radially to change the size of the roller extending to the cleaning disk; the roller tray is provided with a plurality of circumferential groove ports, the roller The slots are radially arranged at equal angles, and the cleaning discs on both sides of the roller groove are provided with spring holes for inserting springs, moving chutes for inserting the rotating shaft of the rollers, and limiting blocks for restricting the movement of the rotating shaft, and the springs are offset from the rotating shafts. , the shaft can be offset from the limit block To avoid the shaft from moving out of the moving chute. The roller can be moved in the radial direction of the cleaning disk to change the overhanging size. When the pipe is narrowed or there is a roadblock, the roller can be retracted so that the traction head can smoothly pass through the narrow pipe. Advantageous effects of the invention

Beneficial effect

[0017] The first cleaning disc and the second cleaning disc are moved forward by the pulling line, so that the debris in the pipeline is moved forward together, the debris in the pipeline is removed, and the first cleaning disc and the second cleaning disc are removed. The diameter is larger than the cable, which effectively prevents debris from causing damage to the cable skin and improves the quality of work.
