The cooperation design between the middle section 422 and the guide strip 431 allows the erasing component 42 to cover the entire display area, ensuring no omissions and improving the thoroughness of erasing. The connecting section 420 firmly connects the sliding part 41 and the middle section 422 together, reducing the risk of loosening and falling off during use and improving the stability of the entire erasing component 40. The design of the middle section 422 makes the erasing part 421 more stably installed on the fixed part, enhancing the overall structural rigidity and extending the service life of the product.

[0030] The fixed keel 430 is installed on the bottom surface of the display component 20, and the guide strip 431 is installed on the bottom surface of the fixed keel 430; the guide strip 431 on the side opposite to the fixed keel 430 is set to cooperate with the middle section 422. The cooperation between the guide strip 431 and the middle section 422 significantly reduces the friction of the middle section 422 during sliding, making the erasing component 42 move more smoothly on the frame 10. The design of the guide strip 431 ensures the accurate movement trajectory of the middle section 422, preventing the erasing component 42 from deviating during sliding and improving the uniformity and reliability of erasing. The guiding effect of the guide strip 431 ensures uniform contact between the erasing part 421 and the display component 20, avoiding problems such as incomplete or excessive erasing in certain areas. The cooperation design between the middle section 422 and the guide strip 431 allows the erasing component 42 to cover the entire display area, ensuring no omissions and improving the thoroughness of erasing. The fixed keel 430 is installed on the bottom surface of the display component 20, providing stable support, ensuring the accurate installation position of the guide strip 431, and enhancing the stability of the entire erasing component 40. The combined design of the fixed keel 430 and the guide strip 431 makes the entire structure more robust and extends the service life of the product.

[0031] Please refer to Figure 1 and Figure 2The frame 10 also includes a slide groove 11 for the sliding member 41 to slide along; the slide groove 11 is configured as a curved arc groove; the guide strip 431 is configured as an arc segment that matches the arc groove. The design of the arc groove 11 and the arc guide strip 431 can significantly reduce the friction between the sliding member 41 and the middle section 422 during the sliding process, making the wiping member 42 move more smoothly on the frame 10; the cooperation between the arc guide strip 431 and the arc groove 11 ensures that the movement trajectory of the sliding member 41 and the middle section 422 is accurate, avoiding deviation during the sliding process and improving the uniformity and reliability of wiping; the precise guiding effect of the arc guide strip 431 ensures that the wiping part 421 has uniform contact with the display component 20, avoiding localized contact. The problem of incomplete or excessive erasing is addressed; the arc design allows the erasing element 42 to cover the entire display area along the arc trajectory, ensuring no omissions and improving the thoroughness of erasing; the design of the arc groove 11 and the arc guide strip 431 ensures that the sliding element 41 and the middle section 422 are subjected to uniform force throughout the sliding process, reducing wear and damage caused by uneven local force; the arc-shaped guide strip 431 and groove 11 are more durable, reducing wear on the sliding element 41 during long-term use and extending the product's service life.
