Fig. 2 is a schematic view of the utility model (side view) in use.

Explanation of symbols in the figure: cabinet 1, suction cup 2, touch display screen 3, computer host 4, speaker 5, inclined panel 6, keyboard 7, stylus 8, microphone 9.

Detailed ways

The utility model is described in detail below with the best embodiment.

As shown in Figure 1-2, the mathematical image graphics demonstrator includes a box body 1 and a touch screen 3, and a suction cup 2 is fixed on the back of the touch screen 3, and the touch screen 3 is adsorbed to an appropriate position on the blackboard by the suction cup when in use . A computer mainframe 4 is arranged in the casing 1, and an oblique panel 6 is arranged on the casing 1, and a keyboard 7 is fixed on the oblique panel 6; during use, the casing 1 is arranged on the platform, which is convenient for the teacher to operate the keyboard. A sound box 5 is respectively fixed on the left and right sides of the box body 1; the computer host 4 is connected to the touch display screen 3 through wires.

The host computer 4 is also connected to the stylus 8 through wires, and the stylus 8 is arranged in the spring clip on the side of the touch screen 3. This structure is convenient for the teacher to use the stylus to operate on the touch screen.

Host computer 4 is also connected with a microphone 9 by wire, and microphone 9 is used when the teacher has a big class.

Finally, it should be noted that obviously, the above-mentioned embodiments are only examples for clearly illustrating the utility model, rather than limiting the implementation manner. For those of ordinary skill in the art, other changes or changes in different forms can be made on the basis of the above description. It is not necessary and impossible to exhaustively list all the implementation manners here. And the obvious changes or changes derived therefrom are still within the protection scope of the present utility model.
