On the basis of the above solution, there are three upright columns, and the three upright columns are evenly and fixedly connected to the upper outer side of the bottom plate.

On the basis of the above scheme, there are three movable columns, and the three movable columns are uniformly and fixedly connected to the lower end of the ring, and the three movable columns correspond to the three upright columns, and are slidably matched with the installation holes .

On the basis of the above scheme, the alcohol placement plate is slidably matched with the three columns.

Compared with the prior art, the utility model has the beneficial effects that: a tripod for chemical experiments adopts a new structure, so that the height of the tripod for chemical experiments can be adjusted at will according to needs, the adjustment is simple and convenient, and the alcohol lamp is placed on the board The height can also be fine-tuned, which can accurately adjust the use of the inner flame and outer flame of the flame when the alcohol lamp is heated. If students are doing experiments, it can make it easier for students to understand the inner flame and outer flame of the flame and the inner flame and outer flame of the flame The utility model has the advantages of simple structure, convenient operation, good use effect and strong practicability.
