High-strength glass fiber yarn

The utility model relates to the technical field of glass fiber yarns, and discloses a high-strength glass fiber yarn which comprises a base body and a glass fiber precursor, a flame-retardant layer is arranged on the top of the glass fiber precursor, an anti-static film is arranged on the top of the flame-retardant layer, a wear-resistant layer is arranged on the top of the anti-static film, and a fixing device is arranged on the outer surface of the base body. The fixing device comprises a mounting groove, a slot, a fixing pin, a fixing ring and a connecting block. According to the high-strength glass fiber yarn, by arranging the fixing pins, the inserting grooves and the fixing rings, during machining, the fixing rings and the fixing pins can be arranged on the surface of the base body, then glass fiber precursors are wound, the fixing pins are moved to enable the glass fiber precursors and the base body to be attached together, the fixing pins can downwards extrude the glass fiber precursors, and therefor
