The utility model discloses a high-stability double-helix DNA (deoxyribonucleic acid) model for biological teaching, which belongs to the field of DNA models and can be used for effectively reducing the difficulty when a transverse chain is axially inserted into a DNA longitudinal framework through the arrangement of an elastic middle part and a transverse chain shaft. On the other hand, through the cooperation effect of the spliced transverse chain shaft, the inner suction hemisphere blocks and the inner locking positioning lines, the transverse chain shaft and the inner locking positioning lines can be intertwined after the transverse chain shaft is inserted into the DNA longitudinal framework, the transverse chain shaft is effectively prevented from falling off from the DNA longitudinalframework, and the assembling efficiency of the model is effectively improved; and under the action of mutual magnetic attraction force, the winding effect between the inner locking positioning lineand the transverse chain s
