Technical Field

[0002] At present, geometric knowledge is needed in the teaching process. However, because it is the first time for students to come into contact with geometric shapes and some students have relatively shallow spatial imagination, it is relatively difficult for them to understand the knowledge taught in solid geometry courses, which increases the difficulty of teaching for teachers. Drawing on the blackboard means that the standard angles of various geometric shapes are less accurate, which is very troublesome for teachers, resulting in poor teaching quality and affecting teaching results. If they demonstrate by holding various solid geometric pieces, they cannot hold their hands up for a long time.

[0003] To this end, the applicant has conducted useful explorations and attempts and found solutions to the above problems. The technical solutions to be introduced below were produced in this context. Summary of the invention

[0053] In order to enable learners to view the combination of angles between geometric pieces more intuitively, the utility model is placed at a high place on the podium. First, the geometric piece is inserted into the clamping groove 10, and then the geometric piece is clamped stably by the damping plates 12 on the two side walls of the clamping groove 10. Because the geometric piece is provided with magnetism, the magnetic geometric piece will magnetically attract the metal piece 11, so that the geometric piece is clamped more stably on the clamping block 8. A number of geometric pieces of different shapes are clamped by each clamping block 8 respectively, and then the vertical adjustment screw 61 and the horizontal adjustment screw 51 are rotated respectively, so that the vertical adjustment screw 61 moves up and down on the vertical support seat 6, and the horizontal adjustment screw 51 moves left and right on the horizontal support seat 5, so as to adjust the position of the clamped geometric piece. The matching arrangement of the sliding key and the keyway 17 plays a role.

Then, the knobs of the locking nuts 18 are used to support the vertical rod 3 or the cross bar 4, so as to fix the positions of the lateral support seat 5 and the vertical support seat 6. The geometric pieces are provided with magnets so that they can be attracted to each other, so that the geometric pieces can be assembled together, which is convenient for checking the combination of the angles between the geometric pieces after assembly. The geometric pieces have different colors, so that the viewer can see the shape of each geometric piece more clearly, so as to achieve the purpose of more intuitive teaching. The blocking plate 14 blocks other components so that the observer in front of it can only see the viewing angle of the geometric module 2 through the observation port 15, so as to enable each observer to concentrate more on viewing.

[0054] The arrangement of two vertical poles 3, two right-angle sleeves 9 and a horizontal pole 4 facilitates assembly and disassembly, and is quick and convenient.
