DETAILED DESCRIPTION

[0022] In order to more clearly illustrate the technical solutions in the embodiments of the utility model or the prior art, the utility model will be briefly introduced below in combination with the drawings and the description of the embodiments or the prior art. Obviously, the following description of the structure of the drawings is only some embodiments of the utility model. For ordinary technicians in this field, other drawings can also be obtained based on these drawings without creative work. It should be noted that the description of these embodiments is used to help understand the utility model, but does not constitute a limitation of the utility model.

[0023] Example:

[0024] The specifications and sizes of conventional gel pens and water-based pens on the market are diverse, and it is difficult for the compatible pen holders to be interoperable. Consumers cannot freely replace refills of different types and specifications without changing the pen holder, which is inconvenient in use. Therefore, we propose a pen holder that can be used for multiple types of refills. The specific solution is as follows:

[0025] like Figure 1 , Figure 4 As shown, the present embodiment discloses a pen holder that can be used for various types of pen refills, specifically comprising a pen holder 1 and a pen base 2, wherein the pen holder 1 and the pen base 2 are threadedly assembled and connected.

[0026] like Figure 2-3 As shown, in order to make the pen body 1 adapt to pen bodies 1 of different specifications, the pen body 1 includes a rod body 101, and a threaded sleeve 102 is integrally formed at the bottom end of the rod body 101; an annular bracket 103 is integrally formed on the inner wall of the connection position between the threaded sleeve 102 and the rod body 101, and a clamping device 4 for fixing the pen core 3 is installed at the position of the annular bracket 103.

[0027] At the same time, if Figure 3As shown, the pen base 2 includes a holding body 201; the holding body 201 includes a pen barrel 211, and the two ends of the pen barrel 211 are respectively integrally formed with a threaded screw end 212 and a pen head 213, a pen tip positioning hole 214 is opened in the middle of the pen head 213, and a positioning ring 215 is integrally formed on the inner side of the pen head 213 and located at the periphery of the pen tip positioning hole 214, and a plurality of vertical first positioning cards 216 and second positioning cards 217 are respectively integrally formed on the inner side of the pen head 213 and around the circumference of the positioning ring 215, and the first positioning cards 216 and the second positioning cards 217 are equidistantly distributed around the circumference of the positioning ring 215, and the first positioning cards 216 and the second positioning cards 217 are equidistantly distributed around the circumference of the positioning ring 215, and the first positioning cards 216 and the second positioning cards 217 are equidistantly distributed around the circumference of the positioning ring 215. A positioning card 216 and a second positioning card 217 are designed to be alternately distributed on the circumference of the positioning ring 215. The edge of the first positioning card 216 is designed in a stepped shape and forms a middle support 218 and a top support 219. The middle support 218 is located between the top of the second positioning card 217 and the top support 219. The height designs of the top support 219, the middle support 218 and the second positioning card correspond one to one to the three oil pipe lengths of the current conventional refills 3, and the inner diameters of the positioning ring 215 and the pen tip positioning hole 214 are respectively adapted to the front end sizes of the two different thicknesses of the oil pipes of the current conventional refills 3.

[0028] In the whole design scheme, the inner side design of the pen head 213 at the front end of the pen base 2 can make the pen head 213 of the pen holder 1 effectively position the oil pipe part for the refills 3 of different types and specifications. Secondly, combined with the installation and structure of the clamping device 4, during the threaded assembly process between the pen base 2 and the pen holder 1, the force exerted by the pen base 2 on the clamping device 4 can realize the clamping and fixing of the refill 3, which changes the traditional fixing method of the refill 3, so that the pen holder 1 is no longer limited by the specifications and structural dimensions of the refill 3, so that the pen holder 1 can achieve the purpose of interoperability with various conventional refills 3 commonly seen on the market.

[0029] In order to improve the comfort of holding the pen holder 1, Figure 1 As shown, the outer surface of the grip body 201 is covered with a layer of soft rubber cover 202, and the surface of the soft rubber cover 202 is frosted.

[0030] like Figure 3 As shown, when the pen base 2 and the pen holder 1 are threadedly assembled, in order to enable the clamping device 4 to effectively clamp and fix the pen refill 3, the clamping device 4 includes a clamping ring 401 adapted to the bracket 103, and one end of the clamping ring 401 is integrally formed with a plurality of wedge blocks 402 at equal distances around the circumference, and an annular groove 404 with a circular arc cross-section is integrally formed at the position where the inner side of the clamping ring 401 is connected to the wedge block 402. The design of the annular groove 404 mainly serves to make the connection between the wedge block 402 and the clamping ring 401 have better elasticity, which is conducive to the wedge block 402 being tilted toward the middle of the pen holder 1 under the pressure of the threaded screwing end 212, thereby achieving the clamping of the pen refill 3.

[0031] like Figure 2 As shown, in order to enable the pen base 2 to smoothly squeeze the clamping device 4 so that it can firmly clamp the pen core 3, the outer side of its wedge block 402 is designed in an arc shape, the threaded screwing end 212 at the end of the pen barrel 211 is matched with the inner thread of the threaded sleeve 102 at the end of the pen shaft 1, and the front end of the inner side of the threaded screwing end 212 at the end of the pen barrel 211 is chamfered, and the inner side of the front end of the threaded screwing end 212 is slidably fitted with the outer surface of the wedge block 402.

[0032] like Figure 3 As shown, a layer of rubber pad 403 is glued to the inner side of each wedge block 402, and the end of the rubber pad 403 close to the pen base 2 is bent outward and forms a trumpet structure at the front end of the clamping device 4. The design of the rubber pad 403 can increase the friction between the clamping device 4 and the surface of the pen core 3 to avoid displacement of the pen core 3 during writing.

[0033] When fixing the refills 3 of different specifications, the front end oil pipe of the refill 3 is inserted into the inner side of the pen head 213 at the front end of the pen base 2, and the front end oil pipe of the refill 3 is clamped in the corresponding position inside the pen head 213 (a plurality of refill 3 oil pipe positioning grooves composed of the first positioning card 216, the second positioning card 217, the middle support 218, the top support 219 and the positioning ring 215), and then the tail end of the refill 3 is passed through the middle of the clamping device 4, so that the wedge block 402 surrounds the outer side of the refill 3, and the pen base 2 is screwed at this time. When the front end of the pen base 2 hits the back of the wedge block 402, The wedge block 402 is deflected inwardly under the action of the pen base 2, gradually clamping the pen core 3 to achieve fixation of the pen core 3. When performing the clamping operation on pen cores 3 of different thicknesses, the degree of twisting between the pen base 2 and the pen holder 1 is mainly determined. When the clamped pen core 3 is thinner, the twisting depth between the pen base 2 and the pen holder 1 is deeper, and when the pen base 2 contacts the wedge block 402, the inclination angle of the wedge block 402 is larger. On the contrary, the twisting depth between the pen base 2 and the pen holder 1 is slightly shorter, and the inclination angle of the wedge block 402 is smaller, thereby achieving effective clamping and fixation of pen cores 3 of different thicknesses.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
