This utility model provides a stirring blade group structure and a stirring device using the same. The stirring blade group structure comprises a stirring blade seat and at least three groups of stirring blades. The stirring blade groups are fixed on the stirring blade seat and each stirring blade group includes a stirring shaft, a lower stirring blade and an upper stirring blade. The upper stirring blade and the lower stirring blade are crossingly disposed at one end of the stirring shaft. The upper stirring blade is U-shaped. When the stirring blade group structure is in use, each stirring blade group is disposed on the stirring blade seat and composed of different stirring blades. Each stirring blade is formed in different angles, therefore, when they rotate for stirring and cutting, they can reach the food at different positions and angles, so that there is no dead angle available and meanwhile the stirring blades in different groups will not affect each other. The three groups of the stirring blades cooperate with one another to fully stir the food in the container, hence the stirring efficiency and effects are improved.
