Low-resistance long-life seat plate

The low-resistance long-life seat plate comprises a seat plate body and fixing assemblies, and the fixing assemblies are arranged in the circumferential direction of the seat plate body; an assembling groove is formed in the middle of the base plate body and used for containing a wire winding wheel. A first through groove and a second through groove are formed in the two sides of the seat plate body correspondingly, and the first through groove, the assembling groove and the second through groove communicate in sequence; the assembling groove is provided with a resistance reducing assembly used for reducing resistance between the wire winding wheel and the base plate. The resistance reducing assembly comprises a first circular ring protruding part, a second circular ring protruding part and a plurality of resistance reducing columns. By arranging the resistance reducing assembly, the friction resistance between the winding nylon and the seat plate is reduced, the abrasion of the contact surface of the winding
