The invention discloses a safety belt lock catch with a one-way torsion force limiting device. The safety belt lock catch comprises a lock catch head, the one-way torsion force limiting device and a vehicle body connecting plate. The one-way torsion force limiting device comprises a left end cover, a force limiting rod, a roller, a right end cover and a steel wire rope assembly. The left side end cover and the right side end cover form an accommodating cavity; the rollers can rotate in the accommodating cavity; the force limiting rod comprises a cylindrical section and tooth-shaped splines located at the two ends of the cylindrical section. The force limiting rod penetrates into the roller; the tooth-shaped spline at one end of the force limiting rod is meshed with the boss spline, and the other end of the force limiting rod is meshed with the spline hole. The height can be adjusted according to needs through rivet connection. The device is suitable for being installed on a seat or a vehicle body bottom plate. The double-head lock catch is small in size, light in weight, suitable for simultaneous use of double-head lock catches in the rear row, and suitable for different vehicle types and different use environments. The output size of the force limiting value can be adjusted by adjusting the size of the force limiting rod, the cost is low, and the device is suitable for large-scale application and popularization.
