The invention relates to a safety warning tripod fixing structure on a tail gate. The safety warning tripod fixing structure comprises a fixing groove and a safety warning tripod, wherein the fixing groove is formed in the front surface of a lower decorative board of the tail gate; the accommodating state of the safety warning tripod is rod-shaped; the fixing groove is strip-shaped and is shorter than the safety warning tripod, external openings allowing the two ends of the safety warning tripod to extend into the back surface of a lower decorative board of the tail gate are formed in the two sides of the fixing groove; springs capable of being propped against the two ends of the safety warning tripod are arranged at the back of the lower decorative board of the tail gate; the safety warning tripod is arranged in the fixing groove, and the two ends of the safety warning tripod extend into the back surface of the lower decorative board of the tail gate through the external openings and are propped against the springs. The safety warning tripod fixing structure provided by the invention is simple in structure and convenient to manufacture; the safety warning tripod is accommodated through the fixing groove, so that the interior space is not occupied, and the safety is high; the fixing groove is used for performing upper and lower limiting on the safety warning tripod; the springs on the two sides are used for lateral limiting on the safety warning tripod and can prevent noise generated by collision between the safety warning tripod and the lower decorative board of the tail gate.
