In 1964, fischertechnik was born in Germany. It is an intelligent and interesting assembly model of engineering technology with high technical content. It is an ideal teaching aid for demonstrating scientific principles and technical processes, and it is also an embodiment of the world. Learning tools with the most advanced educational concepts provide the best carrier for innovative education and innovative experiments. The main components of Fischer's creative combination model are made of high-quality nylon plastic, with precise dimensions and not easy to wear, which can ensure repeated disassembly and assembly without affecting the accuracy of the model combination; the patented design of the industrial dovetail groove of the components allows six sides to be spliced, which is unique The design allows for arbitrary combination and expansion.
