[0027] The storage mechanism 2 includes a fixing groove 201, which is provided at the front end of the inner wall of the fixing frame 1, a spring 202 is fixedly connected to the front end of the inner wall of the fixing groove 201, a pressing plate 203 is fixedly connected to the rear end of the spring 202, a connecting column 204 is fixedly connected to the front end of the pressing plate 203, a movable hole 205 is provided at the front end of the fixing frame 1, a connecting column 204 is movably connected to the inner wall of the movable hole 205, and a connecting plate 206 is fixedly connected to the front end of the connecting column 204. By using the fixing frame 1 and the pressing plate 203, the spring 202 and other parts, the pressing plate 203 can compress the display board to be displayed by the elasticity of the spring, and the use of the top cover 207 can fix the display board in the fixing frame 1, so that it is very convenient to use when replacing the display board for disassembly, reducing the workload of the operator.

[0028] Furthermore, the right end of the fixed frame 1 is hinged with a top cover 207 through a hinge, and a limiting groove 208 is provided at the lower end of the top cover 207. By using the top cover 207, the top cover 207 can be opened and closed during use, so that the subsequent installation of the display board can be conveniently taken out or put in through the top cover 207, and the display board can be better fixed.

[0029] Furthermore, a movable groove 209 is opened at the left end of the fixed frame 1, and a sliding rod 210 is fixedly connected to the left end of the inner wall of the movable groove 209. By using the movable groove 209 and the sliding rod 210, the sliding rod 210 is fixed in the movable groove 209, which facilitates the subsequent pressing of the U-shaped block 211, makes it easier to open and close the top cover 207, and enhances the stability of the subsequent display board.

[0030] Furthermore, a U-shaped block 211 is provided at the upper end of the inner wall of the movable groove 209, and a spring 212 is fixedly connected to the right end of the U-shaped block 211. By using the spring 212 and the U-shaped block 211, after the U-shaped block 211 compresses the spring 212, the restoring force of the spring 212 can be utilized, so that the U-shaped block 211 can be limited in the limit groove 208, thereby facilitating the subsequent use of the top cover 207.

[0031] Furthermore, a sliding hole 213 is opened at the left end of the U-shaped block 211, and the sliding rod 210 is slidably connected to the inner wall of the sliding hole 213. By using the sliding hole 213 and the sliding rod 210, the sliding rod 210 limits the sliding hole 213, so that the U-shaped block 211 can only move left and right along the sliding rod 210, which is convenient for the subsequent fixation of the display board.

[0032] Embodiment 2

[0033] Combination Figure 1-5On the basis of the first embodiment, the adjustment mechanism 4 further comprises an electric telescopic rod 401, the electric telescopic rod 401 is fixedly connected to the upper end of the base 3, the left end of the fixed frame 1 is fixedly connected to a rotating rod 402, the outer wall of the rotating rod 402 is movably connected to a connecting block 403 through a bearing, the connecting block 403 is fixedly connected to the upper end of the base 3, the front end of the electric telescopic rod 401 is fixedly connected to a movable block 404, the upper end of the movable block 404 is provided with a rotating groove 405, the right end of the fixed frame 1 is movably connected to a long plate 406 through a pin shaft, and the long plate 406 is movably connected to the inner wall of the rotating groove 405 through a pin shaft, by using the electric telescopic rod 401, the connecting block 403, the slider 407 and other parts, and by using the electric telescopic rod 401 to move the movable block 404, the angle thereof is adjusted, thereby enhancing the viewing effect of the students.

[0034] Furthermore, a slider 407 is fixedly connected to the lower end of the movable block 404, and a slide groove 408 is provided at the upper end of the base 3. The slider 407 is slidably connected to the inner wall of the slide groove 408. By using the slider 407 and the slide groove 408, the slider 407 can only slide in the slide groove 408, so that the slide groove 408 limits the slider 407, thereby facilitating the movement of the movable block 404.

[0035] When the display panel 206 is in a fixed position, the display panel 206 is moved by pulling the connecting plate 206, and then the display panel is put into a suitable position, so that the spring 1 202 compresses the pressing plate 203, so that the pressing plate 203 presses the display panel to prevent the display panel from being separated from the fixed frame 1, and then the top cover 207 is turned over, and the U-shaped block 211 is compressed, so that the U-shaped block 211 compresses the spring 212, so that the U-shaped block 211 can enter the limiting groove 208, and then the U-shaped block 211 fixes the limiting groove 208, so that the display panel will not fall out of the fixed frame 1, and when the angle needs to be adjusted, the electric telescopic rod 401 can be started to make the movable block 404 adjust the position of the long board 406, so as to facilitate the subsequent angle change of the entire fixed frame 1.
