[0002] During the film blowing process of plastic film, it is necessary to use a film blowing bubble stabilizing rack to clamp the film bubble from the outside so that it can be transported stably. For film bubbles of different diameters, the bubble stabilizing rods that clamp the film bubble need to be adjusted inside and outside to adapt to film bubbles of different diameters.
