[0032] like Figure 1-Figure 8 As shown, a hands-on teaching aid disclosed in the utility model comprises a first plate body 1, a second plate body 2 and a third plate body 3, wherein the upper surface of the second plate body 2 is provided with a groove 4 for placing the first plate body 1, and the shape and size of the groove 4 are adapted to the first plate body 1, the third plate body 3 is hinged to one side of the second plate body 2, and the lower surface of the second plate body 2 is provided with protrusions 5 distributed in a rectangular array;

[0033] An insert block 6 is also included. A slot 7 for placing the insert block 6 is provided on the upper surface of the first plate body 1 . A through hole 8 matching the protrusion 5 is opened in the middle of the insert block 6 .

[0034] In this embodiment, the second plate body 2 is formed into a disc-shaped structure, and the first plate body 1 can be placed in the groove 4 of the second plate body 2. The first plate body 1 can be completely fixed in the second plate body 2, or the first plate body 1 and the second plate body 2 can be set to a detachable state. The first plate body 1 is only embedded in the groove 4 of the second plate body 2, and the first plate body 1 can be taken out by grasping in the slot 7;

[0035] In addition, the protrusion 5 provided at the bottom of the second board body 2 can be used to insert the plug 6. The plug 6 can not only be inserted into the slot 7 of the first board body 1, but also can be sleeved on the protrusion 5 at the bottom of the second board body 2. Different patterns can be formed at the bottom of the second board body 2 by using the same or different types of plugs 6, so that suitable play methods can be selected for children of different ages.

[0036] At the same time, the through hole 8 provided on the plug block 6 can not only be used to connect the protrusion 5, but also the plug block 6 can be used alone to allow children to pass the through hole 8 on the plug block 6 with a thread. Compared with the above two ways of playing to exercise intelligence, it can also exercise finger ability.

[0037] The above-mentioned hinged connection between the third plate body 3 and the second plate body 2 is specifically that the third plate body 3 and the second plate body 2 are connected by a support rod, and the two ends of the support rod are respectively hinged on the second plate body 2 and the third plate body 3 by self-locking hinges 12. When the second plate body 2 is covered on the first plate body 1, the support rod and the third plate body 3 are in a vertical state. At this time, the support rod and the third plate body 3 are self-locking, and the support rod and the second plate body 2 are self-locking. A certain force is required to rotate the third plate body 3. When the support rod rotates 180° around the second plate body 2, the cover plate formed by the third plate body 3 covers the protrusion 5 at the bottom of the second plate body 2. When different playing methods are selected, the disk surface on the other side can be protected.

[0038] Furthermore, the slot 7 includes two slot groups 71, and the two slot groups 71 are arranged on the first plate body 1 at intervals;

[0039] The slot group 71 is composed of at least one row of first slots 711, second slots 712, and third slots 713 arranged in a cyclic sequence;

[0040] The insert block 6 includes a first block 61 , a second block 62 and a third block 63 . The first block 61 is adapted to the shape of the first slot 711 , the second block 62 is adapted to the shape of the second slot 712 , and the third block 63 is adapted to the shape of the third slot 713 .

[0041] In this embodiment, the slot group 71 is configured to include a first slot 711, a second slot 712, and a third slot 713 of three different shapes (in this embodiment, the first slot 711 is a triangular prism slot, the second slot 712 is a cylindrical slot, and the third slot 713 is a rectangular / cuboid slot). Correspondingly, the first block 61, the second block 62, and the third block 63 are configured to have the same shape and size, and can just fit into the slot group 71.

[0042] The arrangement order of the first slot 711, the second slot 712 and the third slot 713 of each slot group 71 may be random or follow a certain rule;

[0043] In addition, the types (shapes) of the slot groups 71 can also be increased, and plug blocks 6 of corresponding shapes can be added at the same time, or one or more slots in each slot group 71 can be combined with one or more plug blocks 6 to further train children's abilities.
