[0023] The connecting assembly 3 includes a movable cylinder 31 fixedly mounted on the bottom surface of the plate body 1, a fixed cylinder 32 fixedly mounted on the top surface of the base 2, a threaded rod 33 rotatably set on the base 2, a connecting nut 34 fixedly mounted on the inner cavity of the movable cylinder 31 and threadedly connected to the threaded rod 33, a fixing ring 35 fixedly mounted on the side wall of the inner cavity of the fixed cylinder 32 and slidably connected to the movable cylinder 31, a bevel gear set 36 set at the internal cavity of the base 2, and a limit block 37 fixedly mounted on the lower end of the movable cylinder 31; the adjusting assembly 4 includes a connecting shaft 43 rotatably set inside the base 2, a turntable 41 fixedly mounted on the end of the connecting shaft 43, a sliding button 42 slidably set on the turntable 41, a ball head rod 47 slidably set on the connecting shaft 43, a connecting rod 45 fixedly connected to the ball head rod 47, a friction ring 44 fixedly mounted on the end of the connecting rod 45, and two ends fixedly connected to the connecting shaft 43 and the ball head rod 47 respectively. The first spring 46 is connected, the second spring 48 whose two ends are fixedly connected to the sliding button 42 and the turntable 41 respectively, and the spherical protrusion 49 fixedly installed on the side of the sliding button 42, the bevel gear set 36 includes two bevel gears that are meshed with each other, one of which is fixedly connected to the threaded rod 33, and the other is fixedly connected to the connecting shaft 43. A sliding groove is provided on the connecting shaft 43 for passing through the two ends of the connecting rod 45, and both ends of the sliding groove are sealed. Friction grooves are provided on the side of the friction ring 44 for enhancing the friction between the base 2. Such designs can provide a certain friction force, and then the friction force can be used to lock the internal structure to improve the stability of the overall device. In the initial state, the spherical protrusion 49 can contact the ball head end of the ball head rod 47. The spherical protrusion 49 is located in the internal cavity of the turntable 41 to ensure that the spherical protrusion 49 can contact the ball head rod 47.

[0024] Working principle: because a plurality of auxiliary cognitive blocks 11 are set on the board 1, and each auxiliary cognitive block 11 is provided with a protrusion in the shape of a number, and the board 1 is also provided with a first magnetic groove 12 and a second magnetic groove 13 for adsorbing the auxiliary cognitive blocks 11, so students manually move the auxiliary cognitive blocks 11 to conduct practical hands-on teaching, so as to achieve the purpose of intuitively feeling the shape characteristics of numbers; and when the height of the board 1 needs to be adjusted, because the movable cylinder 31 fixed on the bottom surface of the board 1 and the fixed cylinder 32 fixed on the base 2 are slidably connected through a fixing ring 35, and the fixed cylinder 32 is fixed on the base 2, the fixing ring 35 is fixed on the board 1. There is a threaded relationship between the connecting nut 34 fixed in the inner cavity of the movable cylinder 31 and the threaded rod 33 rotatably set on the base 2, and the threaded rod 33 is connected to the connecting shaft 43 through the bevel gear set 36 in the inner cavity of the base 2. Therefore, when the connecting shaft 43 rotates, the threaded rod 33 rotates synchronously, thereby driving the movable cylinder 31 to slide on the fixed cylinder 32 to change the height of the plate body 1 to meet actual use requirements; and when the driving connecting shaft 43 rotates, the sliding button 42 is first pushed to slide on the turntable 41, so that the spherical protrusion 49 fixed on the side of the sliding button 42 and the ball head of the ball head rod 47 are engaged. The ends are staggered because the ball rod 47 slidingly set inside the connecting shaft 43 is further connected to the connecting shaft 43 by the first spring 46. The ball rod 47 is fixedly connected to the friction ring 44 through the connecting rod 45. Therefore, after the spherical protrusion 49 and the ball rod 47 are staggered, under the elastic force of the first spring 46, the ball rod 47, the friction ring 44 and the connecting rod 45 slide together, so that a gap is generated between the side of the friction ring 44 and the base 2. Because the turntable 41 and the end of the connecting shaft 43 are fixedly connected, the connecting shaft 43 can be driven by the turntable 41. The plate body 1 is rotated to adjust the height of the plate body 1. After the slide button 42 is finally released, the spherical protrusion 49 contacts the ball end of the ball head rod 47 again under the action of the second spring 48 fixedly connected to the slide button 42 and the turntable 41 at both ends, thereby squeezing the ball head rod 47 to eliminate the gap between the friction ring 44 and the base 2, so that the friction pattern on the friction ring 44 is in close contact with the base 2, and then a certain friction force is formed to limit the rotation of the friction ring 44 and even the connecting shaft 43, and the state of the threaded rod 33 is locked by the bevel gear set 36, thereby locking the height of the plate body 1 and improving the overall stability.

[0025] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
