A dual-mode safety belt cutting knife comprises a main frame, a trigger device, a side cover, a blade compression spring, a cutting knife body, an upper cover, a lower cover and a safety belt. The upper cover is mounted on the main frame, and the lower cover is mounted below the main frame. The safety belt is clamped between the main frame and the lower cover, and the side cover is mounted on oneside of the main frame. One end of the blade compression spring is mounted in a clamping groove formed in the inner side of the side cover, and the other end of the blade compression spring is connected with the cutting knife body; the cutting knife body is slidably mounted in the main frame, and a cutting edge is vertically aligned with the safety belt. The trigger device is mounted on the uppersurface of the upper cover, and the lower portion of the trigger device penetrates out of the upper cover and blocks the cutting knife body. The trigger device is started, and the cutting knife body is not blocked. Under the action of the blade compression spring, the cutting knife body quickly pops up and cuts off the safety belt. When various accidents and traffic accidents happen, trapped people can cut off the safety belt through the device, and the purposes of escape and self-rescue in an emergency state are achieved.
