Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 An embodiment of this utility model provides a Chinese character writing practice board, including a support device 3. A limiting device 2 is fixedly installed at the top of the support device 3. An alignment device 1 is fixedly installed at the top of the side end of the limiting device 2 away from the support device 3. The alignment device 1 includes a contact plate 4, a first rack 5, a support frame 6, a gear 7, and a base rod 8. The contact plate 4 is fixedly installed at the top of the first rack 5. The first rack 5 is slidably inserted into the top of the support frame 6. The support frame 6 is fixedly installed at the top of the base rod 8. The gear 7 is rotatably installed inside the base rod 8, and the first rack 5 meshes with the gear 7.

[0023] The limiting device 2 includes a positioning cavity 9, a second rack 10, an H-shaped locking key 11, a return spring 12, a contact plate 13, a connecting top plate 14, and a guide rod 15. The return spring 12 is symmetrically fixedly installed at the bottom of the interior of the positioning cavity 9. The connecting top plate 14 is fixedly installed at the top of the return spring 12. The contact plate 13 is fixedly installed at the bottom of the side end of the connecting top plate 14. The guide rod 15 is symmetrically fixedly installed at the bottom of the connecting top plate 14 and is located inside the positioning cavity 9. The H-shaped locking key 11 slides through the positioning cavity 9 and is fixedly installed at the bottom of the connecting top plate 14. The second rack 10 is fixedly installed at the end of the H-shaped locking key 11 away from the positioning cavity 9. The positioning cavity 9 is hollow inside, allowing the return spring 12 and the guide rod 15 to run inside the positioning cavity 9.

[0024] The support device 3 includes a displacement crossbar 16, magnetic strips 17, an iron frame 18, and a support pad 19. The iron frame 18 is fixedly installed on both sides of the support pad 19. The magnetic strips 17 are slidably inserted into the top of the iron frame 18. The displacement crossbar 16 is fixedly installed between the two magnetic strips 17. The bottom sides of the displacement crossbar 16 are both arc-shaped, which avoids damage to the paper.

[0025] The side end of the positioning cavity 9 away from the second rack 10 is connected to the support pad 19. The end of the bottom rod 8 away from the first rack 5 is fixedly installed on the side end of the positioning cavity 9 near the second rack 10, which can support the rotation of the gear 7.

[0026] The support frame 6 has slots on the inner side and top of the first rack 5, and a key is fixedly installed on the side end of the first rack 5 to ensure that the contact plate 4 moves up and down in a straight line.

[0027] The second rack 10 meshes with the gear 7 on the side opposite to the first rack 5. The positioning cavity 9 has a vertical groove at the center of the side end of the second rack 10, allowing the second rack 10 to move up and down by driving the connecting top plate 14 through the H-shaped key 11.

[0028] The inner walls of the positioning cavity 9 are symmetrically provided with movable grooves that are adapted to the guide base rod 15, so as to ensure that the connecting top plate 14 moves up and down in a straight line.

[0029] Plastic pads are installed at the bottom of both the contact plate 13 and the support pad 19 to improve the anti-slip performance of the support pad 19.

[0030] Working principle: In use, the paper is placed on the top of the support pad 19, and then the contact plate 4 is pressed down. At this time, the contact plate 4 can drive the first rack 5 to move downward along the surface of the gear 7. When the gear 7 rotates, it can drive the second rack 10 to move upward. It is connected to the connecting top plate 14 through the H-shaped latch 11, so that when the second rack 10 moves upward, it can drive the connecting top plate 14 and the contact plate 13 to move upward. At this time, one end of the paper can be pushed under the contact plate 13. Then the contact plate 4 is released. At this time, the return spring 12... The elasticity causes the connecting top plate 14 to move downwards, and the plastic pad fixed at the bottom of the contact plate 13 contacts the paper on the support pad 19, thus restricting one end of the paper. Then, the displacement bar 16 can be moved to the top of the support pad 19. A groove is provided at the center of the top of the iron frame 18, and the magnetic strip 17 slides into the groove. The displacement bar 16 is then pulled away from the positioning cavity 9, allowing it to move against the surface of the paper and smooth its surface until the displacement bar 16 reaches the paper. At the end, the magnetic strip 17 adheres to the iron frame 18, allowing the displacement-limiting crossbar 16 to be positioned above the paper, thus securing the paper. During use, the first rack 5 slides in a slot within the support frame 6 via a key on its side, enabling it to move linearly up and down within the support frame 6. Simultaneously, the guide rod 15 slides in a movable groove on the inner wall of the positioning cavity 9, ensuring the connecting top plate 14 moves linearly up and down, improving the accuracy of the contact plate 13's alignment with the paper. The H-shaped key 11 moves within the vertical groove of the positioning cavity 9, allowing the second rack 10 to move the connecting top plate 14 during displacement. The plastic pad at the bottom of the support pad 19 adheres to the tabletop, preventing the support pad 19 from shifting again during use. When the paper needs to be removed, the displacement bar 16 can be continuously moved and pulled until it disengages from the paper. Then, the contact plate 4 is pressed again until the contact plate 13 can move upward, allowing the user to remove the paper from the support pad 19 and complete the task.

[0031] Although 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
