The invention relates to an intelligence benefiting device, in particular to an intelligence benefiting device of a mathematics straight line rotation change. The device comprises a main frame body, astraight line change demonstration component, a rotation point moving component, a rotation point positioning component and a fastening component. The straight line can rotate around different positions, the exposed part of the straight line between a lower rectangular frame and an upper rectangular frame can be adjusted, the straight line movement can be controlled by pushing or pulling a push-pull rod, and students can have a deeper understanding of the rotation change of the straight line. The upper rectangular frame is fixedly connected with the upper end of a sliding groove rod, circularthrough holes corresponding to positioning inserting columns are formed in the two corners of the front end of the upper rectangular frame, the positioning inserting columns are inserted in the circular through holes in the upper rectangular frame, the lower rectangular frame is fixedly connected with the lower end of the sliding groove rod, the upper rectangular frame and the lower rectangular frame are of the same size, four L-shaped blocks are connected with the center position of the upper surface of the sliding groove rod through a screw, and the four L-shaped blocks are distributed in acircular pattern.
Description
technical field [0001] The invention relates to a puzzle device, in particular to a mathematical linear rotation change puzzle device. Background technique [0002] A straight line consists of an infinite number of points. Lines are the constituents of faces, which in turn make up volumes. Without endpoints, it extends infinitely to both ends, and the length cannot be measured. A straight line is an axisymmetric figure. It has innumerable axes of symmetry, one of which is itself, and all straight lines of symmetry that are perpendicular to it. There is one and only one straight line passing through two disjoint points on the plane, that is, two disjoint points determine a straight line. On a spherical surface, an infinite number of similar straight lines can be drawn through two points. In order to help students understand the rotation of a straight line, a mathematical straight line rotation change puzzle device is designed. SUMMARY OF THE INVENTION [0003] The inv...
