Embodiment 1
[0029] refer to Figure 1-12 , a shorthand training device based on rural English teaching, comprising a casing 1, a rolling mechanism and a card access mechanism for accessing cards, wherein:
[0030] The card access mechanism is installed inside the casing 1, and sends the card into or out of the casing 1;
[0031] A window 101 is opened on the housing 1 , and a rolling mechanism is arranged in the housing 1 to move the card to the range of the window 101 .
[0032] The card access mechanism includes a top plate 2 and a bottom plate 3. The top plate 2 is provided with a feed port, and the bottom plate 3 is provided with a discharge port. The top plate 2 and the bottom plate 3 are arranged in parallel, and a vertical fixed installation is installed between the top plate 2 and the bottom plate 3. Plate 10, a rotating shaft 14 is rotatably mounted on the mounting plate 10, a cylinder 15 is fixedly connected to the rotating shaft 14, and both ends of the cylinder 15 can be rota...
Embodiment 2
[0036] Further, as Figure 2-7 As shown, the driving mechanism includes a main shaft 9, a first incomplete bevel gear 902, a second incomplete bevel gear 903 and a first bevel gear 23. One end of the main shaft 9 is rotatably installed on the base plate 3, and the other end is rotatably installed on the base plate 3. On the top plate 2, the first incomplete bevel gear 902 and the second incomplete bevel gear 903 are fixed on the main shaft 9, the first bevel gear 23 is fixed on the rotating shaft 14, the first incomplete bevel gear 902 and the second incomplete bevel gear 902. The bevel gear 903 is matched with the first bevel gear 23 .
[0037] The main shaft 9 is driven to rotate, the main shaft 9 will drive the first incomplete bevel gear 902 and the second incomplete bevel gear 903 to rotate, and the first incomplete bevel gear 902 and the second incomplete bevel gear 903 will intermittently rotate during the rotation. It meshes with the first bevel gear 23, wherein:
