The invention relates to the field of food testing, in particular to a multifunctional food safety testing device, comprising a support platform, a limit mechanism, a fixing mechanism, a storage mechanism, a connecting mechanism, a mixing mechanism, a lifting mechanism and a driving mechanism; the interior of the storage mechanism Install the mixing mechanism, the mixing mechanism interferes with the driving mechanism, and the top surface of the storage mechanism is equipped with a fixing mechanism. When the food sample stored in the test tube is put into the inside of the mixing mechanism, the fixing mechanism engages the storage mechanism and fixes the test tube on the storage mechanism. Inside, open the driving mechanism, the driving mechanism rotates and contacts the mixing mechanism, drives the mixing mechanism and the test tube to rotate, so that the food is mixed evenly inside the test tube, and the driving mechanism hits the mixing mechanism, causing the mixing mechanism to vibrate, shaking the food on the inner wall of the test tube Falling, so that the food inside the test tube is mixed more evenly, and the food is mixed inside the test tube, and the food sample will not be contaminated by other impurities, ensuring the accuracy of food testing.
