Specifically, the linear distance between the axis of the first strand 6 and the bottom of the first spiral recess 5 is greater than its own radius. It is understood that the depth of the first strand 6 in the first spiral recess 5 is a depth such that the first strand does not easily slip out of the first spiral recess 5, and the purpose that the first strand 6 does not easily slip out of the first spiral recess 5 can be achieved by changing the depth of the first spiral recess 5 and also by changing the diameter of the first strand.
Specifically, a third strand 8 is arranged between the first strand 6 and the second strand 7 and the corrosion-resistant layer 3, the third strand 8 and the second strand 7 are wound alternately, and the third strand 8 is an irregular strand, so that gaps are conveniently filled. When the structure between the strands changes, for example, the first strand 6 is disconnected, or the rope core 1 deforms, the second strand 7 and the third strand 8 are wound with each other and have a limiting effect, so that the fiber ropes can still be in a use state within a certain time, and a certain buffer time is played for subsequent maintenance.
