The invention is applicable to the technical field of automobiles, and provides a safety belt cutting device. The safety belt cutting device comprises an upper clamping seat, an indented bar, a transmission gear, an intermittent gear, a rotating gear and a stirring piece, wherein the interior of the upper clamping seat is of a hollow structure, the indented bar is slidably arranged on the upper clamping seat and fixedly connected with a blade, the transmission gear is rotatably connected to the upper clamping seat and engaged with the indented bar, the intermittent gear is rotatably connectedto the upper clamping seat and alternately engaged with the transmission gear and the indented bar, the rotating gear is rotatably connected to the upper clamping seat and coaxially and fixedly connected with the intermittent gear, and the stirring piece is used for driving the rotating gear to rotate. The side, away from the indented bar, of the upper clamping seat is fixedly connected with a lower clamping seat, and the lower clamping seat and the upper clamping seat act to clamp a safety belt. The safety belt is cut through the blade which slides in a reciprocating manner, the cutting capacity is high, the efficiency is high, and timely escape is facilitated. The safety belt is clamped through cooperation of the upper clamping seat and the lower clamping seat, and installation is convenient. The safety belt cutting device has the advantages of being simple in structure, convenient to operate, high in cutting efficiency, stable in clamping and convenient to popularize and implement.
