Specific embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
It clearly and completely describes, it is clear that the described embodiments are only a part of the embodiments of the utility model rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work
All other embodiments obtained shall fall within the protection scope of the present invention.
As shown in Figs 1-4, a kind of high flexibility wear-resistant cable, including:
Cable body 5, the cable body 5 are arranged on the inside of protective jacket 4, and the outside of the protective jacket 4 is provided with one
Layer metal armor layers 3, the external activity of the metal armor layers 3 are socketed with movable sleeve 2；
