[0003] A stirring mechanism is usually provided in a disposable reaction bag. Existing stirring mechanisms for disposable reaction bags include: a bottom plastic single blade type in which stirring is driven by a bottom motor and the stirring function is achieved through a single bottom blade; an obliquely inserted single blade type in which stirring is driven by a top motor and fixed by a top bearing; a plastic double blade type in which stirring is driven by a bottom motor and fixed by a bottom bearing; a plastic double blade type in which stirring is driven by a top motor and fixed by top and bottom double bearings; however, a single blade has a poor stirring effect, an oblique insertion has an inconvenient installation problem, and a single bearing fixation has a problem that stirring is prone to shaking; and the stirring shaft and blade positions of the existing stirring mechanism are relatively fixed and cannot be adjusted.
