According to the cable conveying support, the conveying rollers 2 capable of being adjusted up and down are arranged to change the arrangement shape of the conveying rollers 2, so that the lower ends of cables can be pressed against the upper ends of the conveying rollers 2, the conveying rollers 2 can support the cables at the same time, the stress of the single conveying roller 2 is reduced, and the stability of the cable conveying support is improved. The arrangement direction of the plurality of conveying rollers 2 is the same as the bending direction of the cable, so that the radius of the cable which is supported by the plurality of conveying rollers 2 for bending is far more than ten times of the diameter of the cable, and the problems of plastic deformation and the like of the cable are avoided.

In some embodiments, the conveying roller 2 includes a first roller 201, a second roller 202, and a third roller 203, the first roller 201 and the third roller 203 are provided to the frame 1 and rotatable with respect to the frame 1, the second roller 202 is provided between the first roller 201 and the third roller 203, and the second roller 202 is height-adjustable with respect to the frame 1.
