The invention discloses a convenient-to-use power communication cable winding-up and paying-off device. The convenient-to-use power communication cable winding-up and paying-off device comprises a base. Two fixing rods are fixedly arranged on the right side of the upper end of the base and are symmetrically arranged. Winding wheels are arranged between the two fixing rods. The two ends of the twowinding wheels are rotatably connected with the fixing rods through rotating shafts correspondingly. A driving motor is fixedly arranged on the side wall of one fixing rod. An output shaft of the driving motor is fixedly connected with one rotating shaft through a coupling. A portal frame corresponding to the winding wheel in position is fixedly arranged on the left side of the upper end of the base. A T-shaped sliding groove is transversely formed in the lower end of a cross beam of the portal frame. A T-shaped sliding block is slidably connected to the T-shaped sliding groove. A threaded rodis arranged in the T-shaped sliding groove. One end of the threaded rod is rotatably connected with the side wall of one side of the T-shaped sliding groove. The convenient-to-use power communicationcable winding-up and paying-off device is convenient to operate, and enables a cable to be uniformly wound on the winding wheel. The labor force of workers is reduced, and the influence of vibrationon the device can be reduced.
