A three-dimensional geometric model splicing assembly with fixed joints, comprising a number of connecting rods and a number of three-way joints interpolated with each other, is characterized in that each of the three-way joints has two bottom connecting claws and a vertical connecting claw, the vertical connecting claw is perpendicular to the plane of the axis of the two bottom connecting claws; and according to the two bottom connecting claws, the three-way joint has two bottom connecting claws. The three-way joint has at least two angles between the axes of the bottom connecting claw; one end of the vertical connecting claw is provided with a coaxial socket hole near the bottom connecting claw; and the splicing assembly also includes a number of cylindrical one-way joints, the two ends of the one-way joint are plug-in segments, the outer diameter of the middle segment is greater than the plug-in segments, and the three segments are arranged. For coaxial integration molding. With a number of one-word joints and a number of different angles of the three-way joints, there is also an extension of the outside of the three-way joint socket, so that many kinds of three-dimensional geometric models can be spliced, which helps users to enhance the concept of three-dimensional geometry, interesting.
