A safety-type locking seat and lock head, wherein the safety-type locking seat includes a seat (10) and a pole (11). There is a left-right tooth (14,15) on the pole (11). The pole (11) stands on one end of the seat (10) and a safety aperture base (12) lies on the other end, meanwhile, a safety aperture (13) is located on the safety aperture base (12). Moreover, the safety aperture base's width is smaller than the seat's. The stress point on the top of the safety aperture base (12) does not align itself with the safety aperture (13) in the direction of vertical. The safety-type lock head includes a tooth part (21) and a safety aperture part (22) formed with the tooth part (21). There is a safety aperture (23) on the safety aperture part (22). Furthermore, a bearing block (27) is set on the safety aperture part (22) to support it. Having finished the installation, the bearing block's bottom will be in the same plane with the seat's. The locking seat and lock head can improve the security for container because their safety apertures (13,23) are not apt to be distorted.
