[0019] This utility model has the following beneficial effects:

[0020] 1. Compared with existing technologies, this three-dimensional Chinese character teaching aid uses a fixed frame, sliding rod, locking post, fork, and spring. Moving the fork moves the sliding rod, which in turn moves the locking post, compressing the spring and disengaging the locking post from one of the locking holes. Then, the inner sleeve post moves downwards to the appropriate position. Moving the fork again, under the elasticity of the spring, causes the locking post to engage with the corresponding locking hole, thus fixing the inner sleeve post and raising the height of the mounting plate for easier viewing by students in the back rows.

[0021] 2. Compared with existing technologies, this three-dimensional Chinese character teaching aid uses a rotating rod, knob, worm gear, and worm wheel. Rotating the knob drives the rotating rod, which in turn drives the worm gear. The worm gear, through the worm wheel, drives the rotating rod, which in turn drives the outer sleeve column to rotate, thus rotating the outer sleeve column into the connecting frame. This reduces the size of the mounting plate and makes it easier to place. Attached Figure Description

[0033] To facilitate adjustment, the snap-fit ​​structure 11 includes a fixed frame 111 fixedly connected to one side of the outer sleeve post 8. A sliding rod 112 is slidably connected through one side of the fixed frame 111. One end of the sliding rod 112 is fixedly connected to a snap-fit ​​post 113. A spring 115 is sleeved on the sliding rod 112. One end of the spring 115 is fixedly connected to the inside of the fixed frame 111, and the other end is fixedly connected to one side of the snap-fit ​​post 113. The snap-fit ​​post 113 is slidably connected through one side of the outer sleeve post 8 and is adapted to a corresponding snap-fit ​​hole. The other end of the sliding rod 112 rotates... A fork 114 is connected to the movable connection. One side of the fork 114 is in contact with one side of the fixed frame 111. When the fork 114 is moved, the fork 114 drives the sliding rod 112 to move. The sliding rod 112 drives the locking post 113 to move and compresses the spring 115, so that the locking post 113 disengages from one of the locking holes. Then the inner sleeve post 9 is moved downward to the appropriate position. Then the fork 114 is moved again. Under the elasticity of the spring 115, the locking post 113 is locked into the corresponding locking hole, and the inner sleeve post 9 is fixed.

A worm wheel 124 is fixedly connected to the rotating rod 7, and the worm wheel 124 meshes with the worm gear 123. Rotating the knob 122 causes the rotating rod 121 to rotate, which in turn causes the worm gear 123 to rotate. The worm gear 123 then drives the rotating rod 7 to rotate via the worm wheel 124. The rotating rod 7 then drives the outer sleeve post 8 to rotate, rotating the outer sleeve post 8 into the connecting frame 6, reducing the volume of the mounting plate 1 and facilitating placement.

[0035] Working principle: Place the mounting plate 1 on the teaching desk, turn the fork 114, the fork 114 drives the sliding rod 112 to move, the sliding rod 112 drives the locking post 113 to move, and compresses the spring 115, so that the locking post 113 disengages from one of the locking holes. Then move the inner sleeve post 9 downward to the appropriate position, and then turn the fork 114 again. Under the elasticity of the spring 115, the locking post 113 is locked into the corresponding locking hole, fixing the inner sleeve post 9 and raising the height of the mounting plate 1, making it easier for students in the back row to watch. After the teaching is completed, retract the inner sleeve post 9 into the outer sleeve post 8, and then turn the knob 122. The knob 122 drives the rotating rod 121 to rotate, the rotating rod 121 drives the worm gear 123 to rotate, the worm gear 123 drives the rotating rod 7 to rotate through the worm wheel 124, the rotating rod 7 drives the outer sleeve post 8 to rotate, rotating the outer sleeve post 8 into the connecting frame 6, reducing the volume of the mounting plate 1 and making it easier to place.
