[0002] In scientific research, medical testing, and chemical experiments, as a commonly used experimental tool, the design of a test tube rack is directly related to the convenience of experimental operations, the safety of test tubes, and the accuracy of experimental results. Most traditional test tube racks adopt a fixed design and cannot be flexibly adjusted according to the size of the test tubes, which to a certain extent limits their scope of application and efficiency. Especially when dealing with test tubes of different sizes and materials, traditional test tube racks often seem inadequate, easily causing problems such as unstable placement resulting in spillage of the contents or damage to the test tubes. For example, maintaining the stability of test tubes in different vibration environments and automatically adjusting the spacing to adapt to test tubes of different diameters. These problems have restricted the process of experimental automation. Summary of the Utility Model

[0003] The purpose of the utility model is to provide an adaptive fixed test tube rack, which solves the problem that traditional test tube racks cannot be flexibly adjusted according to the sizes of different test tubes, easily leading to unstable placement of test tubes, resulting in spillage of the contents or damage to the test tubes.

[0031] For an adaptive fixed test tube rack of the present utility model, a test tube is placed inside the device housing 1, and its bottom is made to contact the groove 202 on the base 2. Then, the test tube moves downward under the action of its own gravity, causing the base 2 to move downward and compressing the bottom surface spring 201 below it. At the same time, under the action of the side spring 301, the side plate 3 moves towards the test tube along the inclined surface at the bottom of the side plate 3, making the arc-shaped buffer pad 302 contact the side wall of the test tube. Then, hold the handle 104 and pull up the fixing plate 103 so that the elastic rope 102 moves in the sliding groove 101, causing the fixing plate 103 to move from the side of the device housing 1 to above the device housing 1.
