Abstract

The invention discloses a test tube rack used for chemical experiments and used for placing test tubes with different lengths, wherein the test tube rack includes a base. Two sides of the top of the base are each fixedly connected with a stand column, and the top of the base is provided with an insert plate; the top of the insert plate is provided with insert slots; the top of the base is providedwith grooves cooperatively used with the insert slots; two sides of the insert plate are each fixedly connected with a sleeve block. Through cooperative use of the stand columns, clamp holes, a fixing box, screw rods, a sliding groove, a sliding block, screw sleeves, a connecting rod, sliding sleeves, sliding rods, a support rod, a through groove, springs, a torsion block, a clamp rod and the sleeve blocks, the problems that a conventional test tube rack used for chemical experiments is fixed and the height cannot be adjusted according to the test tubes with different heights are solved, thetest tube rack used for the chemical experiments has the advantages of adjustable height, a user can adjust the height of the test tube rack according to the height of the test tubes, the user can conveniently place the test tubes with different lengths, and the practicability of the test tube rack for chemical experiments is improved.
