The invention discloses a special safety belt buckle. The special safety belt buckle comprises an upper pressure plate, a lower fixed plate, a rotating nut, a cylinder bolt, a rotating shaft and a rotating pin, wherein the upper pressure plate is arranged above the lower fixed plate; the rotating pin is arranged in the left end connected position of the upper pressure plate and the lower fixed plate; the rotating shaft is arranged at the right end of the lower fixed plate; the bottom of the cylinder bolt is connected with the middle of the rotating shaft; a sawtooth-shaped stripe projection is arranged on the upper surface of the lower fixed plate; and a circular arc projection is arranged at the right end of the upper surface of the upper pressure plate. Through the mode, one end of the special safety belt buckle disclosed by the invention is fixed by the rotating nut, so that the elasticity adjustment is quiteconvenient; the special safety belt buckle is suitable for safety belts with different thicknesses, is long in service life, and is not liable to be ineffective due to abrasion; and the circular arc projection effectively prevents the oscillation of the cylinder bolt in working, so that the safety coefficient is high when a vehicle is impacted.
