[0010] Compared with the prior art, the advantages of the present invention are:

[0011] 1. The utility model places the balloon into the cutting groove of the cutting plate, and starts the cutting assembly to drive the cutter to move for cutting, without the need for manual hand-held scissors for cutting. At the same time, a control assembly is provided to mobilize the movement of the cutting plate and adjust the spacing, so as to facilitate the cutting of balloons of different sizes.

[0012] 2. The utility model achieves the purpose of adjusting the spacing by controlling the cylinder to drive the movable plates to move toward each other.
