[0010] Specifically, the wear-resistant sleeve includes a first wear-resistant layer, a metal mesh layer and a second wear-resistant layer, and the metal mesh layer is located between the first wear-resistant layer and the second wear-resistant layer.
[0011] By adopting the above technical solution, the setting of the first wear-resistant layer, the metal mesh layer and the second wear-resistant layer improves the wear-resistant property of the wear-resistant sleeve.
[0012] Specifically, support blocks are integrally formed at the bottom ends of the two clamp seats, and two through holes are formed in each of the two support blocks.
[0013] By adopting the above technical solution, passing the end of the bolt through the through hole in the support block facilitates fixing the support block at a specified position and can prevent the clamp seat and the cable body from displacing.
