Low-friction-resistance sliding groove and multipurpose buckle cable saddle system

The invention relates to a low-friction-resistance sliding groove and a multipurpose buckle cable saddle system, the low-friction-resistance sliding groove is an engineering plastic alloy component, the low-friction-resistance sliding groove is arranged in an arc shape in the length direction of the low-friction-resistance sliding groove, one end of the low-friction-resistance sliding groove is tangent to the horizontal line, the other end of the low-friction-resistance sliding groove is bent downwards, and the low-friction-resistance sliding groove is used for arranging a buckle cable. By utilizing the characteristics of large bearing capacity, high compression resistance, high wear resistance, corrosion resistance, good toughness, low friction coefficient, self-lubrication, no maintenance and long service life of engineering plastic alloy, the low-friction sliding chute is used for replacing a traditional cable saddle pulley to be matched with the guide of a buckle cable; the problems that the pulley is eas
