An air sealing device includes a holding unit and an outer clamp mounted on the holding unit to clamp the holding unit. The holding unit includes a first clamping bar and a second clamping bar pivotally connected with the first clamping bar. The holding unit has a clamping space defined between the first clamping bar and the second clamping bar. Thus, the opened upper end of the bag is clamped in the clamping space of the holding unit, wound around the first clamping bar and the second clamping bar of the holding unit and pressed by the outer clamp so that the opened upper end of the bag is sealed by the holding unit and the outer clamp closely and tightly. |
