The invention discloses a chemical tripod having a test tube clamping function. The chemical tripod comprises an iron ring and support legs. The lower end surface of the iron ring is uniformly provided with the three support legs. The three support legs are vertically fixed and are arranged on the lower end surface of the iron ring at equal intervals. The iron ring and the three support legs are integrally connected and fixed. The outer side of each one of the support legs is provided with a sliding rail. The sliding rail vertically fits to the outer end surface of the support leg. A sliding block is vertically and slidingly connected in the sliding rail. A vertical bar is vertically and fixedly connected to the sliding block. A rotation block is fixedly connected to the top of the vertical bar. Four side end surfaces of the rotation block are symmetrically and fixedly connected to spring clips. Multiple test tubes can be clamped on the chemical tripod. The test tubes containing test solutions can be heated on an alcohol lamp.
