In this utility model, different test tubes can be automatically clamped and the overall adaptability and ease of use of the device are improved, and the test tubes are prevented from falling off under the action of centrifugation;

[0003] Although the existing centrifugal analysis device can carry and limit the test tube through the connecting plate, there are still other problems during use, such as it is inconvenient to take the test tube. Although it is convenient to put the test tube in, the top of the test tube will be in contact with the top of the connecting plate after being put in. There is no fulcrum for the hands when taking it. One hand needs to reach in and hold the tube body to lift it up, and the other hand can take it down. It is time-consuming and laborious, and the connecting plate cannot be replaced separately. The connecting plate plays the role of carrying the test tube and maintaining balance in the device. When a connecting plate is deformed and causes imbalance and needs to be replaced, the whole can only be replaced together with the rotating cylinder, which increases the maintenance cost of the device. In order to solve the above-mentioned problems, we propose a centrifugal analysis device for soil testing. Utility Model Content
