The invention provides a standard stay wire wedge-shaped tail wire binding machine, and belongs to the field of wire binding. According to the technical essential, fixing traction forceps comprise forceps heads, connecting rods and air cylinders. The forceps heads and the connecting rods are of integrated structures, the forceps heads are provided with semicircular jaws, and the air cylinders arefixed to the tail ends of the connecting rods through connecting double ears. A bearing block is fixed to supports and is basically perpendicular to sizing blocks, the forceps heads are located in a bearing hole of the bearing, the forceps heads of the fixing traction forceps are ingeniously arranged in the bearing hole of the bearing, a center region of a winding disc can be formed by winding rods, and uniform circular winding is achieved.
