A number of convex ribs 14 are fixedly installed on the top of the support base 12. The demonstration board 10 is hinged to the support base 12. The snap ring 15 can be snap-connected to the convex ribs 14 at different positions to adjust the inclination angle of the demonstration board 10. A storage groove for the support rod 13 to flip is provided on the back of the demonstration board 10. The support rod 13 is located in the storage groove and is rotatably connected to the inner wall of the demonstration board 10. The snap ring 15 is fixedly installed at the bottom of the support rod 13. The snap ring 15 forms a C-shaped metal ring with an opening. The convex rib 14 forms a cylindrical protrusion. The opening size of the snap ring 15 is smaller than the diameter of the convex rib 14. In this solution, by hinging the demonstration board 10 to the support base 12 and flipping the demonstration board 10 to adjust the angle of the front wall of the demonstration board 10, it is convenient for students to operate. Rotate the support rod 13, and the snap ring 15 at the bottom of the support rod 13 is snap-connected to the convex rib 14 at the corresponding position. The circumferential surface of the convex rib 14 squeezes the snap ring 15 to deform and expand. When the convex rib 14 enters the snap ring 15, the snap ring 15 returns to lock the convex rib 14. The support rod 13 is in an inclined state to support the demonstration board 10, realizing the back support of the demonstration board 10. Furthermore, the inclination angle of the demonstration board 10 can be adjusted and locked, and the demonstration board 10 can be adjusted according to requirements.

[0028] As Figure 4 and Figure 5 shown, a connecting component is provided between the demonstration board 10 and the ammeter 11 for the detachable connection between the ammeter 11 and the demonstration board 10;

As a supplement to the above scheme, when installing the equipment, taking the ammeter 11 as an example, the two female heads 20 on the wall of the ammeter 11 are inserted into the circular hole. As the female head 20 is inserted, the protrusion 22 gradually enters the deformation groove 23 to make the petal-like structure of the female head 20 expand and deform, and then the petal-like structure of the female head 20 resists the inner wall of the circular hole, thereby realizing the installation and fixation of the ammeter 11.
