[0002] Centrifuge tube oscillator is a commonly used instrument in laboratories. It is mainly used for centrifugal separation and mixing liquids. It usually uses brushless motors to drive containers of different diameters for high-speed vortex mixing. For example, a multi-tube vortex oscillator uses brushless motors to oscillate the centrifuge tubes on the bracket to quickly rotate and oscillate, thereby achieving liquid mixing.
[0003] During food processing inspection, liquid needs to be poured into a centrifuge tube and placed in an oscillating device for mixing. However, when placing the centrifuge tube, a centrifuge tube rack is usually required. The existing oscillating device lacks a clamping and fixing structure for centrifuge tube racks of different sizes, resulting in low adaptability of the device and troublesome operation. Based on the shortcomings of the existing technology, the utility model designs a centrifuge tube oscillating device for food inspection. Utility Model Content

[0025] See also Figure 4-5 A pressure plate structure 5 is installed on both sides of the top of the main body 1 of the oscillation device, and the pressure plate structure 5 includes two sliding rods 51. A sleeve 52 is slidably installed on the outer surface of the two sliding rods 51, and a limit block is set on the top of the two sliding rods 51. The internal threads of the two sleeves 52 are installed with fastening bolts 53, and one end of the two fastening bolts 53 can pass through the sleeve 52.
