The communication cable pay-off device in the prior art has a simple structure, but it is generally easy to cause the cable to be damaged during use. For example, the patent with publication number: CN210084606U discloses a communication cable pay-off device, including a base and a pay-off frame arranged on the base, the pay-off frame is rotatably connected to the base; the pay-off frame includes an annular fixed groove and a pay-off shaft rotatably arranged in the annular fixed groove, and the two ends of the pay-off shaft are provided with a first arc-shaped slider and a second arc-shaped slider adapted to the annular fixed groove, and the two ends of the pay-off shaft are respectively rotatably connected to the first arc-shaped slider and the second arc-shaped slider through bearings.
