[0007] When the eight-claw end is in the limiting state, the rubber piece is in the state of being clamped by the eight-claw end; the pen mouth releases the limitation of the eight-claw end by pressing the pen cap, so that the eight-claw end releases the rubber piece, and the rubber piece can slide out of the pen tip; when the pressing state is released, all structures are reset under the action of the spring, and the eight-claw end clamps the rubber piece again.
[0008] Preferably, a sliding groove is arranged on the pen mouth in the axial direction; a abutting piece is arranged on the outer diameter of the inner rod close to the eight-claw end; and the abutting piece can slide in the sliding groove.
[0009] Preferably, a mounting port is arranged on the end of the pen mouth close to the abutting piece; the mounting port and the sliding groove are on the same axis, and the diameter of the mounting port is smaller than that of the sliding groove.
[0010] As preferred, the abutting piece is triangular, and the bottom side of the abutting piece abuts at the joint of the mounting port and the sliding groove.
[0011] As preferred, the shape of the rubber piece is cylindrical.
[0012] In summary, the advantages of the utility model are as follows:
[0013] The utility model discloses a press rubber eraser adopts the pen type presser design, and user only needs to press the pen cap to control the extension and retraction of the rubber piece easily. This design greatly simplifies the use steps of the traditional rubber eraser, avoids the cumbersome operation of manual breaking and clamping the rubber, and can protect the surface of the rubber from being contaminated and dirty, thereby affecting the erasing effect, and can improve the use efficiency and user experience.

[0021] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.
[0022] In the description of the present application, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.
[0023] It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.
[0024] The specific embodiments of the present application will be described in detail below with reference to the accompanying drawings.
[0025] As shown in Figures 1 to 6 , an eraser includes a pen-type pressing member 1 and a rubber member 2 installed inside it, which has a structure similar to that of a pressing automatic pen, and users only need to press the pen cap 5 to easily control the extension and retraction of the rubber member 2. This design greatly simplifies the use steps of a traditional eraser, avoids the cumbersome operation of manually prying and clamping the rubber, and improves the use efficiency and user experience.
[0026] Specifically, as shown in Figures 1 to 6 , since the internal structure of the pen-type pressing member 1 is similar to that of a pressing automatic pen, it will not be described in detail. It includes a pen tip 3, a pen barrel 4 and a pen cap 5 arranged in sequence, and an inner rod installed inside the pen barrel 4; the inner diameter of the pen barrel 4 is provided with an embedded groove 7, the outer diameter of the inner rod near the pen cap 5 is provided with a limiting ring 8, a certain distance is provided between the limiting ring 8 and the embedded groove 7, and a spring 9 for the rebound of the pen-type pressing member 1 is provided in the distance.
[0027] The cooperation of the spring 9, the limiting ring 8 and the embedded groove 7 ensures the stable movement of the inner rod in the pen barrel 4, avoids the problem of structural looseness caused by frequent use, and prolongs the service life of the product.
[0028] The end of the inner rod near the pen tip 3 is an eight-prong end 10, the inner diameter of the pen barrel 4 opposite to it is provided with an expansion space for the eight-prong end 10 to open, and the outer diameter of the eight-prong end 10 is provided with a pen mouth 11 to limit its opening.
[0029] When the octopus end 10 is in the limiting state, the rubber 2 is in the state of being clamped by the octopus end 10, and the pen mouth 11 is released from the limitation of the octopus end 10 by pressing the pen cap 5, so that the octopus end 10 releases the rubber 2 and can slide out of the pen tip 3; when the pressing state is released, all structures are reset under the action of the spring 9, and the octopus end 10 clamps the rubber 2 again.
[0030] The design of the octopus end 10 enables the rubber 2 to be stably clamped when not in use, avoiding loosening and falling off of the rubber 2, and ensuring stability and reliability in use. The action of the spring 9 enables the pressing member to automatically reset after the pressing state is released, ensuring that the octopus end 10 can clamp the rubber 2 in time and improving the reliability of use.
[0031] As shown in Figure 6 , the pen mouth 11 is provided with a sliding groove 12 arranged in the axial direction, and the inner rod is provided with an abutting piece 13 near the outer diameter of the octopus end 10. When the pen cap 5 is pressed, the inner rod 6 will move towards the pen tip 3, at which time the abutting piece 13 will slide in the sliding groove 12 and move from the left end to the right end of the sliding groove 12, and the octopus end 10 will expand in the expansion space to release the clamping state of the rubber 2. The sliding groove 12 and the abutting piece 13 are arranged to make the inner rod slide more smoothly, reduce the friction resistance, and improve the flexibility of operation.
[0032] The pen mouth 11 is provided with a mounting hole 14 at one end near the abutting piece 13, the mounting hole 14 is on the same axis as the sliding groove 12, and the diameter of the mounting hole 14 is smaller than that of the sliding groove 12, which can better install the abutting piece 13 into the sliding groove 12.
[0033] As shown in Figure 3 and Figure 4 , the abutting piece 13 adopts a triangular structure design, so that its top end can better enter from the mounting hole 14. When it enters the sliding groove 12, the bottom edge of the abutting piece 13 abuts at the junction of the mounting hole 14 and the sliding groove 12.
[0034] The rubber 2 adopts a cylindrical rubber 2, which is not only convenient for production and processing, but also can be better installed in the above-mentioned pen-type pressing member 1. By adjusting the thickness of the octopus end 10, different sizes of rubber 2 can be installed, and different sizes of rubber 2 can be adapted, enhancing the applicability of the product. The smaller the diameter of the rubber 2, the more detailed the details can be erased, such as the convenience of erasing details in drawing.
[0035] The above is the description of the embodiments of the present application, through the above description of the disclosed embodiments, the skilled in the art can realize or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to these embodiments shown herein, but will be consistent with the widest scope consistent with the principles and novel features disclosed herein.
