Vortex mixer

The utility model discloses a vortex mixer which comprises a vortex mixer body, an oscillation disc is installed on the inner side of the upper end of the vortex mixer body, first buffer cotton is installed in the oscillation disc, a first inserting groove is formed in the upper end of the first buffer cotton, and a fixing frame is installed on the outer side of the upper end of the vortex mixer body. An adjusting mechanism is arranged at the upper end of the fixing frame. By adopting the structure, when samples need to be mixed, a sample test tube is inserted into the first slot, then the top frame is driven to move downwards through the adjusting mechanism, and the position of the top frame is stabilized through the sliding assembly, so that the top frame can drive the pressure plate to move downwards stably; the upper end of the sample test tube is inserted into the second slot, so that the effect of stabilizing the position of the sample test tube is achieved, the height of the pressure plate is more conv
