The utility model provides a barrel body positioning die which comprises a frame body, a plurality of vertically-through containing grooves are formed in the frame body at equal intervals, the containing grooves are used for containing firework barrel bodies, and the two ends between every two adjacent containing grooves are separated through partition blocks respectively. The included angles between the center lines of the containing grooves from the middle to the two sides and the center line of the frame body are sequentially increased, so that the firework barrel formed by positioning the multiple containing grooves is ignited and then jetted to form fan-shaped fireworks. The angle of the firework cylinder is limited by setting the included angle between the center line of the containing groove and the center line of the frame body, and the distance between every two adjacent firework cylinders is limited by setting the width of the partition block, so that the angle of a single firework cylinder and the
