When installing the core, simply insert the core into the pen cap assembly, allowing the locking block to slide on the inner wall of the guide assembly. As the locking block 1 slides away from the guide assembly, it comes into contact with the top of the sliding plate. Continued pressing causes the spring to elastically deform and contract, moving the sliding plate downwards. The locking block 3 on the sliding plate surface slides on the inner wall of the sliding groove. At this point, several locking blocks are positioned on one side of several locking plates. Twisting the core counterclockwise causes one end of several locking blocks to engage with the inside of the locking plate, thus securing the core. When the core needs to be replaced, simply... Holding the top of the makeup pen core by hand and turning it clockwise disengages several locking blocks from the locking plate. At this point, the locking blocks are directly below the guide assembly. The spring returns to its elastic deformation, and the locking blocks on the surface of the sliding plate slide on the inner wall of the sliding groove, causing the sliding plate to move upward. The sliding plate then moves one end of the makeup pen core towards the outside of the pen cap assembly and squeezes it out, completing the replacement of the makeup pen core. This method is simple to operate and convenient to use. It solves the problems of traditional makeup pens, where the entire pen needs to be discarded when the core is used up or damaged due to the pen cap and fixed core, resulting in resource waste, and the cumbersome process of replacing the core, which requires the use of tools such as pliers, making the operation more troublesome.

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0027] Please refer to the following: Figures 1 to 6 ,in, Figure 1 A schematic diagram of the extrusion assembly with replaceable inner core and the overall structure of the cosmetic pen having the assembly provided by this utility model; Figure 2 Schematic diagram of the extrusion assembly with replaceable inner core and the cosmetic part having the assembly provided by this utility model Figure 1 ; Figure 3 Schematic diagram of the extrusion assembly with replaceable inner core and the cosmetic pen portion having the assembly provided by this utility model Figure 2 ; Figure 4 for Figure 3 Enlarged structural diagram at point A; Figure 5 A cross-sectional view of the extrusion assembly with replaceable inner core and the cosmetic pen having the assembly provided by this utility model. Figure 6 This is a schematic diagram of the installation of the connecting components.

[0028] In practical implementation, an extrusion assembly with a replaceable inner core, such as... Figures 1 to 6 As shown, the device includes a makeup pen core 21 inserted inside the pen sleeve assembly. A mounting plate 3 is fixed on the inner wall of the pen sleeve assembly. Several equally spaced sliding grooves 14 are provided on the inner wall of the pen sleeve assembly. Several equally spaced locking blocks 23 are provided on the outer ring of the makeup pen core 21. A guide assembly is fixed on the inner wall of the pen sleeve assembly. An extrusion telescopic assembly is also fixed on the inner wall of the pen sleeve assembly. The extrusion telescopic assembly is located below the guide assembly.

[0029] The extrusion telescopic assembly includes a fixed plate 4, a spring 41, and a sliding plate 42. The fixed plate 4 is fixed on the inner wall of the pen cap assembly. The two ends of the spring 41 are fixedly connected to the top of the fixed plate 4 and the bottom of the sliding plate 42, respectively. Several equally spaced locking blocks 421 are fixed on the outer side of the sliding plate 42. Several locking blocks 421 slide on the inner wall of the slide groove 14. Several equally spaced locking plates 422 are also fixed on the top of the sliding plate 42. Several locking blocks 23 are respectively engaged with the surfaces of several locking plates 422.

[0030] It should be noted that the extrusion-type telescopic component is used to replace the inner core 21 of the makeup pen by extrusion.

[0031] It should be noted that, by setting up the slide groove 14, the locking block 23, the locking block 421, the locking plate 422, and the guide assembly, when installing the makeup pen core 21, simply insert the makeup pen core 21 into the pen cap assembly, allowing the locking block 23 to slide on the inner wall of the guide assembly. When the locking block 23 slides away from the guide assembly, it is in contact with the top of the slide plate 42. Continuing to press, the spring 41 undergoes elastic deformation and contracts, causing the slide plate 42 to move downwards. The locking block 421 on the surface of the slide plate 42 slides on the inner wall of the slide groove 14. At this time, several locking blocks 23 are respectively located on one side of several locking plates 422. Twisting the makeup pen core counterclockwise... The inner core 21 causes one end of several locking blocks 23 to engage with the inside of the locking plate 422, thus fixing the inner core 21. When the inner core 21 needs to be replaced, simply hold the top of the inner core 21 and turn it clockwise to disengage the locking blocks 23 from the locking plate 422. At this time, the locking blocks 23 are located directly below the guide assembly, the spring 41 returns to its elastic deformation, and the locking blocks 421 on the surface of the slide plate 42 slide on the inner wall of the slide groove 14, causing the slide plate 42 to move upward. The slide plate 42 causes one end of the inner core 21 to move towards the outside of the pen cap assembly and be squeezed out, thus completing the replacement of the inner core 21.

[0032] For reference Figures 1 to 6 As shown, an extrusion assembly with a replaceable inner core is provided. The pen sleeve assembly includes a pen sleeve 1, a pen sleeve 2 13, and a connecting assembly located between the pen sleeve 1 and the pen sleeve 2 13. The pen sleeve 1 and the pen sleeve 2 13 are screwed together by the connecting assembly.

[0033] The connecting components include connecting sleeve 11 and connecting sleeve 2 12. Pen sleeve 1, connecting sleeve 11, connecting sleeve 2 12 and pen sleeve 2 13 are all screwed together by threads 15.

[0034] It should be noted that the connecting component is used to connect pen cap 1 and pen cap 2 13. By adding or removing the connecting component, it is suitable for the installation and use of makeup pen cores 21 of different lengths. When the connecting component is removed, pen cap 1 and pen cap 2 13 can be screwed together to complete the installation of the pen cap assembly. This device is suitable for the installation and use of makeup pen cores 21 of different lengths and has the advantages of simple installation and wide applicability.

[0035] refer to Figures 1 to 6 As shown, a number of equally spaced grooves 14 are provided on the inner side wall of the pen cap 1. A makeup pen core 21 is inserted into the pen cap assembly. A pen tip 22 and a pen plug 2 are fixed at both ends of the makeup pen core 21, respectively.

[0036] The guide assembly includes several mounting plates 3, which are fixed on the inner wall of the pen cap 1, and each of the mounting plates 3 has a groove 31 on its top.

[0037] The inner wall of the pen cap 1 is also fixed with several equally spaced mounting plates 2 32, and the outer side of the mounting plates 2 32 is provided with a slot 1 321.

[0038] It should be noted that several equally spaced grooves 14 are used to guide the inner core 21 of the makeup brush.

[0039] Makeup pen core 21: A pen tip 22 and an end cap 2 are fixed at both ends respectively. The pen tip 22 is used to apply cosmetics, while the end cap 2 is used to seal the end of the core to prevent leakage of internal substances.

[0040] The guide assembly includes several mounting plates 3, which are fixed on the inner wall of the pen cap 1. Each mounting plate 3 has a groove 31 on its top. The groove 14 and the groove 31 work together to provide more precise guidance for the inner core 21 of the makeup pen.

[0041] It should be further explained that by designing slide 14, slide 2 31 and slot 1 321, users can more easily install and replace the makeup pen core 21 without complicated operations or tools.

[0042] It should be further explained that the mounting plate 3 and mounting plate 32 in the guide assembly provide stable guidance and support for the makeup pen core 21, ensuring that the makeup pen core 21 will not shake or shift during use, thereby improving the comfort and accuracy of use.

[0043] refer to Figures 1 to 6 As shown, the extrusion telescopic component is fixed on the inner wall of the pen sleeve 1, the fixing plate 4 is fixed on the inner wall of the pen sleeve 1, and the fixing plate 4 is located on one side of the mounting plate 3.

[0044] Several connecting plates 24 are fixed to the bottom of the end pen plug 2, and a second locking block 25 is fixed to the bottom of each of the connecting plates 24.

[0045] When the end pen plug 2 is turned, several locking blocks 25 engage with the surfaces of several mounting plates 32, and several locking blocks 23 engage with the surfaces of several mounting plates 422 respectively.

[0046] It should be noted that when installing the makeup pen core 21, the slot 1 321 and the block 2 25 are engaged. That is, when installing the makeup pen core 21, the makeup pen core 21 is inserted into the pen sleeve assembly, and the block 1 23 slides on the inner wall of the guide assembly. When the block 1 23 slides away from the guide assembly, the block 1 23 is just in contact with the top of the slide plate 42. If you continue to press, the spring 41 will deform elastically and contract, causing the slide plate 42 to move down. The block 3 421 on the surface of the slide plate 42 slides on the inner wall of the groove 1 14. At this time, the blocks 1 23 are located on one side of the plates 422 respectively. Twisting the makeup pen core 21 counterclockwise makes one end of the blocks 1 23 engage with the inside of the plates 422. At this time, the blocks 2 25 engage with the surface of the mounting plates 2 32, thus completing the fixation of the makeup pen core 21.

[0047] The working principle of this utility model is as follows: By setting up a slide groove 14, a locking block 23, a locking block 421, a locking plate 422, and a guide assembly, when installing the makeup pen core 21, simply insert the makeup pen core 21 into the pen sleeve assembly, causing the locking block 23 to slide on the inner wall of the guide assembly. When the locking block 23 slides away from the guide assembly, it is in contact with the top of the slide plate 42. Continuing to press, the spring 41 undergoes elastic deformation and contracts, causing the slide plate 42 to move downwards. The locking block 421 on the surface of the slide plate 42 slides on the inner wall of the slide groove 14. At this time, several locking blocks 23 are located on one side of several locking plates 422. Twisting the makeup pen core 21 counterclockwise causes one end of several locking blocks 23 to... The inner core 21 of the makeup brush is fixed by engaging with the inside of the card plate 422 and engaging with the surface of the mounting plates 32. When the inner core 21 of the makeup brush needs to be replaced, simply hold the top of the inner core 21 of the makeup brush and turn it clockwise to disengage the first card block 23 from the card plate 422 and the second card block 25 from the mounting plates 32. At this time, the first card block 23 is located directly below the guide assembly, the spring 41 returns to its elastic deformation, and the third card block 421 on the surface of the slide plate 42 slides on the inner wall of the slide groove 14, causing the slide plate 42 to move upward. The slide plate 42 causes one end of the inner core 21 of the makeup brush to move towards the outside of the pen cap assembly and be squeezed out, thus completing the replacement of the inner core 21 of the makeup brush.
