[0002] The constant temperature water bath used in the laboratory currently does not have a convenient fixing device for test tubes, beakers and other experimental instruments. When there is a lot of water in the water bath, or when the experimental instrument to be kept constant temperature has a round bottom, these light and small instruments are easy to tilt during the experiment, causing the solution to leak, seriously affecting the experiment. If they are fixed manually, the hot water can easily cause harm to people, and a lot of time and energy are wasted, and burns are likely to occur. Therefore, we propose an electric constant temperature water bath. Utility Model Content
