[0023] Through the above arrangement, only the rotation of the driving structure 4 is needed to realize the extension and retraction of the eraser elements 3, which is simple and compact in structure, avoiding the common problems of jamming and deviation in traditional sliding mechanisms. The guide structure 11 ensures the stability of the movement of the sliding members 2 and avoids skewing. The bidirectional rotation control of the driving structure 4 improves the flexibility of use, and can complete the extension or storage of the eraser device according to the rotation direction. The eraser elements 3 can be completely stored in the base 1, effectively protecting them from pollution or wear and tear, and improving the durability and user experience of the overall product.

[0024] More specifically, the driving structure 4 includes a cap 41 and a cover body 42, the cover body 42 is sleeved on the outer peripheral part of the base 1, and the cap 41 is fixedly arranged on the cover body 42 or integrally formed with the cover body 42; the bottom surface of the cap 41 is provided with a groove 43 for driving the movement of the two sliding members, and the top of the sliding member is provided with a protruding part matched with the groove 43. The rotation of the cap 41 realizes the driving of the sliding members 2, without the need to set up a complex transmission mechanism, reducing the manufacturing difficulty and cost. The cover ring serves as a rotating support and limiting structure, improving the matching precision between the driving structure 4 and the base 1 and enhancing the assembly stability.

[0025] Further, the side of the cover body 42 is provided with an opening 44 for the eraser element 3 to pass through; the base 1 is provided with a limiting structure 12 which is clamped at the bottom edge position of the opening 44, used to limit the axial disengagement of the driving structure 4 relative to the base 1, and the limiting structure 12 and the bottom edge of the opening 44 can slide relative to each other. Through the above arrangement, on the basis of keeping the eraser element 3 to smoothly stretch and retract, the axial disengagement problem of the driving structure 4 caused by uneven force or misoperation during use is effectively prevented, and the safety and durability of the product are improved. At the same time, through the relative sliding fit of the limiting structure 12 and the edge of the opening 44, stable constraint of the driving structure 4 is realized without sacrificing the flexibility of operation, and the structural reliability of the device is optimized.

[0026] As shown in Figure 1 , the side wall of the cover body 42 is provided with a sawtooth pattern, thereby enhancing the user's grip feeling, improving the sensitivity and controllability of the rotation operation, reducing the risk of slipping of wet fingers during use, and improving the overall use comfort and safety.

[0027] As shown in Figure 2 , the top of the guide structure 11 is provided with a pair of oppositely arranged guide grooves 13, and the two sides of the sliding piece 2 are respectively provided with limiting sliding tongues 22 which are slidingly arranged in the guide grooves 13, thereby effectively controlling the movement track of the sliding piece 2, preventing deviation, swing or derailment caused by lateral force, and significantly improving the operation reliability and structural stability of the device.
