The invention relates to a vertical lunching device for an unmanned aerial vehicle carried fire extinguishing bullet. The vertical lunching device comprises a mounting rack, a rotating disc, a rotation power source, two connecting rods and two lunching cylinder components, wherein the rotation power source is used for driving the rotating disc to rotate; the rotation power source is fixedly connected with the mounting rack; the rotating disc is fixedly connected with the output rotating shaft of the rotation power source; the two lunching cylinder components are mounted on two sides of the mounting rack; the lunching cylinder component comprises two clamp parts and rotating rods forming cylinders; the two clamp parts are both hinged with end parts of the mounting rack; the middle parts of the rotation rods are hinged with the mounting rack; one end of each connecting rod is hinged with the rotating disc; the other ends of the two connecting rods are respectively hinged with the other ends of corresponding rods; limiting grooves are formed in the other ends of the rotating rods; limiting bulges are arranged on the two clamp parts; the two limiting convexes are both positioned inside the limiting grooves. By adopting the vertical lunching device, the fire extinguishing bullet can be solidly clamped, is not dropped down when the flying posture of an unmanned aerial vehicle is adjusted, and can be rapidly lunched when being lunched down.
