The implementation conditions adopted in the examples can be further adjusted according to the conditions of the specific manufacturer, and the implementation conditions not specified are usually the conditions in conventional experiments.

[0027] Embodiment 1: A multifunctional teaching and learning machine for children, such as Figure 1-Figure 7 As shown, it includes a learning tablet 1, a shelf 2, a small hook plate 3, a first limiting rod 4, a first spring 5, a large hook plate 6, a second limiting rod 7, a second spring 8, a connecting circular plate 9, a first long plate 10, a connecting support plate 11, a rod insertion plate 12, a third spring 13, a second long plate 17, a clamping assembly, a torsion spring 1701 and a first rounded plate 18. The shelf 2 is clamped on the learning tablet 1, and the lower part of the shelf 2 is slidably connected with a left-right symmetrical small hook plate 3, and the lower part of the shelf 2 is fixedly connected with a left-right symmetrical first limiting rod 4, the small hook plate 3 is slidably connected to the adjacent first limiting rod 4, and a first spring 5 is connected between the small hook plate 3 and the adjacent first limiting rod 4, the left part of the shelf 2 is slidably connected with a top-down symmetrical large hook plate 6, the left part of the shelf 2 is fixedly connected with a top-down symmetrical second limiting rod 7, and the large hook plate 6 is slidably connected to the adjacent second limiting rod 7. A second spring 8 is connected between the large hook plate 6 and the adjacent second limiting rod 7, a connecting circular plate 9 is rotatably connected to the middle position of the rear side of the shelf 2, a first long plate 10 is rotatably connected to the middle of the connecting circular plate 9, the upper and lower parts of the connecting circular plate 9 are rotatably connected to connecting support plates 11, the connecting support plates 11 are slidably connected to the first long plate 10, the upper and lower sides of the first long plate 10 are slidably connected to left-right symmetrical plugging plates 12, the plugging plates 12 are inserted into the adjacent connecting support plates 11, a third spring 13 is connected between the plugging plates 12 and the first long plate 10, a second long plate 17 is rotatably connected to the rear part of the first long plate 10, a clamping assembly for clamping the first long plate 10 is provided on the second long plate 17, a first fillet plate 18 is rotatably connected to the lower part of the second long plate 17, and a left-right symmetrical torsion spring 1701 is connected between the first fillet plate 18 and the second long plate 17.

[0028] When using the device, the staff can place the device in a suitable position, contact the table surface with the first rounded plate 18, and then cooperate with the second long plate 17 and the first long plate 10 to support the connecting circular plate 9. Under the action of the first spring 5 and the second spring 8, the small hook plate 3 and the large hook plate 6 can slide and retract to facilitate the disassembly and assembly of the learning tablet 1 and the shelf 2. When it is necessary to adjust the angle of the learning tablet 1, the staff controls the rod plate 12 to slide back and no longer jam the connecting support plate 11. The third spring 13 is deformed. At this time, the connecting circular plate 9 and the shelf 2 can swing back and forth to adjust the angle of the learning tablet 1. When the angle adjustment is completed, the staff releases the rod plate 12. Under the action of the third spring 13 resetting, the rod plate 12 slides toward each other and is jammed into the connecting support plate 11, thereby fixing the angle of the connecting circular plate 9. At the same time, the staff can also control the shelf 2 to rotate on the connecting circular plate 9, thereby adjusting the placement direction of the learning tablet 1. When it is necessary to adjust the height of the learning tablet 1, the staff releases the positioning component and controls the first long plate 10 and the second long plate 17 to fold or unfold to adjust the height of the learning tablet 1.

[0029] like Figure 5 and Figure 6 As shown, the locking assembly includes a first limit frame 14, a clamping plate 15 and a fourth spring 16. The left and right parts of the upper part of the second long plate 17 are fixedly connected to the first limit frame 14. The first limit frame 14 is slidably connected to the front and rear symmetrical clamping plates 15. The left and right ends of the rear part of the first long plate 10 are polyhedral column structures. The front and rear symmetrical clamping plates 15 clamp adjacent polyhedral column structures. Two fourth springs 16 are connected between the clamping plates 15 and the adjacent first limit frames 14.

[0030] When the height of the learning tablet 1 needs to be adjusted, the staff controls the front and rear symmetrical clamping plates 15 to slide back and forth and open, and the fourth spring 16 is deformed. At this time, the first long board 10 and the second long board 17 can be controlled to fold or unfold, thereby adjusting the height of the learning tablet 1. After the height adjustment is completed, the staff releases the clamping plates 15, and under the action of the fourth spring 16 resetting, the clamping plates 15 slide toward each other and reset to clamp the first long board 10, thereby fixing the angle between the first long board 10 and the second long board 17, thereby fixing the height of the learning tablet 1.

[0031] Embodiment 2: Based on embodiment 1, Figure 1 , Figure 5 and Figure 8As shown, it also includes a clamping assembly for clamping the table top to support the second long board 17, the clamping assembly includes a second limit frame 1801, a second rounded corner plate 19 and a fifth spring 1901, the second limit frame 1801 is fixedly connected to the lower side of the first rounded corner plate 18, the second limit frame 1801 is slidably connected to the second limit frame 1801, and three equidistantly distributed fifth springs 1901 are connected between the second rounded corner plate 19 and the second limit frame 1801.

[0032] When using the device, the staff pushes the second rounded corner plate 19 to slide downward on the second limit frame 1801, and the fifth spring 1901 is deformed. After the second rounded corner plate 19 slides downward, the staff can move the device to a suitable position so that the first rounded corner plate 18 and the second rounded corner plate 19 are mounted on the table top, and then release the second rounded corner plate 19. Under the action of the fifth spring 1901 resetting, the second rounded corner plate 19 slides upward and resets to cooperate with the first rounded corner plate 18 to clamp the table top, thereby fixing the device at a specified position to prevent the learning tablet 1 from shifting or tipping over.

[0033] like Figure 1 , Fig. 9 and Fig.10 As shown, it also includes a covering component for covering and protecting the screen of the learning tablet 1, and the covering component includes a connecting rod 20, a cover plate 21 and a round rod plug plate 22. The right part of the shelf 2 is rotatably connected to the connecting rod 20, and the cover plate 21 is fixedly connected to the connecting rod 20. The left part of the cover plate 21 is slidably connected to the round rod plug plate 22 which is symmetrical up and down. A slot is opened on the front side of the large hook plate 6, and the round rod plug plate 22 is engaged with the adjacent slot.

[0034] When the device is needed, the staff controls the round rod plug plate 22 to slide forward and no longer get stuck in the slot. At this time, the staff can control the cover plate 21 to rotate forward and open. When the learning tablet 1 is used, the staff controls the cover plate 21 to rotate backward and reset, and then controls the round rod plug plate 22 to slide backward and get stuck in the slot, thereby fixing the position of the cover plate 21, and the screen of the learning tablet 1 is covered and protected by the cover plate 21.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
