Abstract
A rotating gas injection device for preventing damage to a rawinsonde balloon, comprising: a handgrip part; a gas injection tube; a ball bearing module including an inner ring, an outer ring, wherein the inner ring and the outer ring are rotatably engaged by means of the balls; and an outer ring cover positioned outside of the outer ring to form space between the outer ring cover and the outer ring; wherein, after an insertion of a neck of the rawinsonde balloon into the space, a distance between the outer ring and the outer ring cover is controlled to be decreased so that the neck of the rawinsonde balloon makes tight contact, and in response to an external force exerted on the neck of the rawinsonde, the outer ring is allowed to be rotated together with the neck by means of the balls.
