Abstract
A mixer is composed of a base, a drive shaft, a plurality of blade seats and mixing blades. The base is engaged with the opening of a liquid container and fastened with a circular body which is fitted over the drive shaft such that the drive shaft is slanted in the liquid container. The blade seats are fastened at an interval with the drive shaft and provided with a pivoting slot in which the mixing blade is fastened pivotally. As the drive shaft is driven by a power source to revolve, the mixing blades are caused to expand by the centrifugal force so as to bring about the mixing effect.
