The high-altitude balloon releasing device as claimed in claim 1, wherein the bottom of the roller support frame (19) is connected with the rotary support turntable (12) through a hinge, so that the roller support frame (19) can rotate at an angle of 30-90 degrees in the balloon releasing process.

5. The high-altitude-balloon dispensing apparatus as claimed in claim 1, wherein the buffer mechanism includes a buffer pad (6), a buffer frame (7) and a buffer spring damping cylinder (8); the buffer frame (7) is hinged with the horizontal support frame, a bevel edge is arranged on the buffer frame (7), the buffer pad (6) is arranged on the bevel edge, and the buffer pad (6) is in contact with the overturned roller (4); the upper end of the buffer spring damping cylinder (8) is connected with the bottom of the buffer frame (7), and the lower end of the buffer spring damping cylinder is connected with the horizontal support frame.

6. A high-altitude-balloon dispensing apparatus as claimed in claim 5, wherein the cushion (6) is formed of a double layer of cushioning material.

7. The high-altitude balloon releasing device as claimed in claim 1, wherein the roller (4) is hollow inside, two ends of the roller are respectively connected with the first rotating shaft (21) and the second rotating shaft (22) through bearings, and the roller (4) freely rotates through the rotating shafts on two sides to ensure that the surface of the balloon is not abraded when the balloon is inflated; the first rotating shaft (21) can be turned over, and the second rotating shaft (22) is locked by the locking mechanism in the balloon inflation stage.
