By adjusting the height, it can be ensured that all students can see the surface content clearly, thereby improving the interactivity between teachers and students during the teaching process.

[0026] In this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, the active column 6 and the driven column 7 form an opening and closing structure through the first connecting rod 8 and the second connecting rod 9, and the bottom of the active column 6 and the driven column 7 are respectively provided with universal wheels; after the first connecting rod 8 and the second connecting rod 9 are folded, the two groups of active columns 6 and the driven column 7 at the bottom can be folded and folded, and the first base 2 and the second base 3 are connected to the surface of the table body 1 with quick-release bolts. It is a detachable structure, so that the equipment will not occupy too much storage space when not in use or transported, and can be directly placed in the corner of the classroom. It is especially important for places with limited classroom space, and the limited space can be used to the maximum extent. The two groups of universal wheels arranged at the bottom can make the teaching board 4 mobile during teaching. When explaining key knowledge, the teaching board 4 can be moved for students to see clearly and concentrate more. Compared with a fixed blackboard, it increases the interactivity between teachers and students in a flexible way, thereby improving teaching efficiency.

[0027] In this embodiment, Figure 4 As shown, arc-shaped sliding grooves are provided on the surfaces of the first base 2 and the second base 3, and the surface of the rocker 202 located on the first base 2 is threadedly connected to the limit block 203, and the teaching board 4 forms a flip structure on the surface of the table body 1 through the first base 2 and the second base 3; through the structure of the first base 2 and the second base 3, the teaching board 4 can present different angles on the surface of the table body 1 in a sliding motion, creating favorable conditions for various environments required in the teaching process.

[0029] In this embodiment, Figure 1 As shown, the expansion board 5 is slidably connected to the inside of the table body 1, and the surface of the expansion board 5 is connected with a semicircular clamping block by spring gluing, and the expansion board 5 is concave; the structure of the expansion board 5 enables the teacher to place the required items on its surface when using the teaching aid in a mobile manner, so that they can pick them up at any time, and its concave structure is not easy to cause the items to fall, and at the same time it is folded into the inside of the table body 1 through the sliding structure, further increasing the functionality and practicality of the teaching aid, while ensuring the convenience of storing the teaching aid.

[0030] The use method and advantages of the utility model: When the auxiliary teaching device which is easy to store is used, the working process is as follows:

[0031] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, first, when the teaching aid is in use, the active column 6 and the driven column 7 are pulled respectively, and the first connecting rod 8 and the second connecting rod 9 are rotated to unfold the teaching aid. When it is necessary to adjust the height, the screw rods 603 on both sides are rotated, and the fixed inner column 602 that is separated from the screw rods 603 can slide inside the outer column 601. Because the top of the inner column 602 and the driven column 7 are both installed on the surface of the table body 1 through hinges, and the driven column 7 is a telescopic structure, when the inner column 602 is stretched, the driven column 7 is stretched accordingly, and the apertures of the inner columns 602 on both sides are kept consistent, and the screw rods 603 and the threaded structure are respectively rotated to fix them inside the outer column 601. During use, the limit block 203 can be rotated to move away from the surface of the first base 2, and the rocker 202 can slide in the arc-shaped slide groove of the first base 2 to adjust the height accordingly. The teaching board 4 requires a teaching angle, and while the rocker 202 of the first base 2 slides, the slider on the other side slides accordingly. After adjusting to the appropriate angle, the limit block 203 is reversed again to fit it to the surface of the first base 2 through the threaded structure. The two sides of the teaching board 4 can be selected accordingly according to the content involved in the teaching process. Pulling the bracket 10 can make it flip 90° perpendicular to the surface of the teaching board 4 for mounting or displaying relevant teaching content. The direction of the teaching board 4 can be changed by the universal wheel at the bottom. During use, relevant objects can be placed by sliding and pulling the expansion board 5. The foldable structures increase the maximum flexibility of the teaching aids during use, provide more relevant teaching strategies for the teaching process, and effectively reduce the floor space of the teaching aids while meeting the functionality, so as to save space.
