Springs A4 connected to the sliding sleeves 5 are provided on both sides of the inner side of the guide grooves 7, and the springs A4 are fitted on the outer side of the guide rods 6. A display screen B8 is provided on the top and bottom of the two sets of sliding sleeves 5 on the same side, which are close to each other. A handle is provided on the top of the two sets of display screens B8 on the side away from each other, which facilitates pulling the display screen B8 to unfold, improving the comfort of adjustment operation. A support component is provided on the bottom of the two sets of display screens B8 on the side away from each other.

[0028] The support assembly includes a plug rod 15, a fixing rod 16, a support leg 17, and a socket 18. The fixing rod 16 is located at the bottom of the two sets of display screens B8 on the side furthest from each other. The support leg 17 is sleeved on the outside of the two sets of fixing rods 16. The bottom of the two sets of support legs 17 is provided with an anti-slip pad to prevent the support leg 17 from slipping and to improve the support effect of the support leg 17. The plug rod 15 is sleeved on one side of the two sets of support legs 17. A limit groove is opened on the top of one side of the support leg 17. A limit block is provided on the outside of the plug rod 15 to slide with the limit groove and to limit the range of motion of the plug rod 15.

[0029] Two sets of insertion holes 18 are provided at the bottom of the two sets of display screens B8 on the side away from each other. The fixing rod 16 is located between the two sets of insertion holes 18, and the distance between the fixing rod 16 and the two sets of insertion holes 18 is the same. When the support leg 17 rotates around the fixing rod 16, the insertion rod 15 can be aligned with the two sets of insertion holes 18, and the fixed position of the support leg 17 can be adjusted. After the display screen B8 is unfolded, the support component can unfold the support leg 17 for support. When the display screen B8 is retracted, the support leg 17 can be flipped and retracted. A transmission component is sleeved in the middle of the bottom of the mounting bracket 3.

[0030] The transmission assembly includes a rack 9, a gear 10, and a movable rod 11. The gear 10 is located in the middle of the bottom of the mounting bracket 3. Movable rods 11 are provided at the bottom of the two sets of sliding sleeves 5. A rack 9 is provided on the side of the two sets of movable rods 11 that are close to each other. The two sets of racks 9 mesh with the two ends of the gear 10 respectively, so that pulling one set of display screens B8 can drive the two sets of display screens B8 to move away from each other, thus improving the convenience of adjustment.

[0031] A storage slot 13 is provided on one end of the inner side of the mounting bracket 3. Connecting rods 14 are sleeved on both sides of one end of the inner side of the storage slot 13. A display screen A2 is provided on one end of the two sets of connecting rods 14. A stop is provided on the end of the two sets of connecting rods 14 away from the display screen A2, which can limit the range of motion of the display screen A2 so that the display screen A2 can be aligned with the display screen B8 after it is unfolded. A spring B12 is sleeved on the outer side of the two sets of connecting rods 14.

[0032] Working principle: When used in teaching, this device displays teaching content through two sets of display screens B8. The split-screen structure of the two sets of display screens B8 facilitates comparative teaching and improves teaching effectiveness.

[0033] When a large screen is needed for teaching, a set of display screens B8 can be pulled by the handle and slid to one side under the guidance of the guide rod 6, overcoming the elastic force of the spring A4. At this time, the set of display screens B8 can drive the rack 9 to move. Through the meshing of the two sets of racks 9 with the gear 10, the two sets of racks 9 move synchronously in opposite directions, thereby driving the two sets of display screens B8 to unfold away from each other. When the two sets of display screens B8 are unfolded, the spring B12, which is in a compressed state, can push the display screen A2 to extend out from the storage slot 13 and combine with the two sets of display screens B8. After combination, a complete large screen can be formed, which is convenient for teaching.

[0034] When the combined large screen is not needed, simply push the display screen A2 with one hand to overcome the elastic force of the spring B12 and retract it into the storage slot 13, and pull the display screen B8 with the other hand to slowly approach it under the elastic force of the spring A4, so that the display screen B8 can be retracted. At this time, the display screen A2 can be hidden in the storage slot 13 and cannot pop out, thus reducing the size of the device.

[0035] When the display screen B8 is unfolded, the insert rod 15 can be pulled out from the top socket 18, and then the support leg 17 can be rotated 180 degrees to support the ground. Then the insert rod 15 can be inserted into the bottom socket 18 for fixation. The two sets of support legs 17 can support the two sets of display screens B8, which improves the stability of the display screen B8 after unfolding. When the display screen B8 is folded up, the support leg 17 can be rotated to the side of the display screen B8 for fixation, and then the support leg 17 can be folded up.
