[0039] Working principle: During use, the wear-resistant layer 1 is wrapped around the outermost side of the core 7, which can effectively provide wear resistance. The corrosion-resistant layer 3, insulation layer 4, and resin layer 5 can effectively play a role in waterproofing and anti-permeation, thereby avoiding damage or short circuit of the cable caused by long-term immersion of the cable in water. When it is necessary to protect the surface of the wear-resistant layer 1 or when the surface of the wear-resistant layer 1 is damaged, the first protective sleeve 8, connecting sleeve 9, and second protective sleeve 10 are attached to the outer surface of the wear-resistant layer 1, and through the fixing plate 15, the angle between the first protective sleeve 8 and the connecting sleeve 9 can be adjusted.

Finally, pull the limiting belt 13 from the side of the positioning block 14 and sleeved the collar 12 on the surface of the fixing block 11, making the first protective sleeve 8 and the second protective sleeve 10 fit more closely to the surface of the wear-resistant layer 1.
