Description

Technical Field

[0001] This utility model relates to the field of telescopic storage technology for utility pens, and more specifically, it relates to a telescopic utility pen that can be twisted and stored. Background Technology

[0002] With the booming development of the beauty industry and the increasing demand from consumers for portable products, integrated and portable beauty tool pens have become the mainstream in the market. Existing telescopic tool pens mainly adopt a press-type telescopic structure. This structure borrows the press principle of traditional ballpoint pens. By pressing the button at the end of the pen, the "pop-out" and "retract" states of the brush head are switched using a spring clip and ratchet mechanism. Although this structure is quick to operate, the button at the end of the pen is very easy to be accidentally pressed during the carrying process, causing the brush head to extend out of the bag and contaminate the brush head and surrounding items.

[0003] Therefore, a new solution is needed to address this problem. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a twisting and retractable tool pen that can drive the brush to move linearly through a threaded transmission. Compared with the press-type, it is more stable and reliable, with a lower probability of misoperation, thereby avoiding the brush from contaminating surrounding items and preventing the brush from being contaminated by surrounding objects.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a twistable and retractable tool pen includes a pen barrel and a pen cap snapped onto the pen barrel. A positioning cylinder is fixedly connected inside the pen barrel. A threaded rod that moves in cooperation is provided inside the positioning cylinder. A limiting post that cooperates to drive the threaded rod to extend and retract inside the positioning cylinder is fixedly connected to the threaded rod. A brush is fixedly connected to the other end of the limiting post. A pen tip is snapped onto the positioning cylinder.

[0006] The present invention is further configured such that: a plurality of guide blocks adapted to the threaded rod are fixedly connected inside the positioning cylinder.

[0007] The present invention is further configured such that: the limiting post is a hexagonal prism, and the pen tip insertion port is adapted to the limiting post.

[0008] The present invention is further configured such that a limiting block is fixedly connected to the threaded rod.

[0009] The present invention is further configured such that a hemispherical block is fixedly connected to the end of the threaded rod away from the limiting block.

[0010] The present invention is further configured such that: a tail cap is snapped onto the pen holder, and a limiting cylinder is snapped onto the tail cap, the limiting cylinder having elastic deformation capability.

[0011] In summary, this utility model has the following beneficial effects: the linear motion of the brush can be driven by threaded transmission, which is more stable and reliable than the pressing type, and the probability of misoperation is lower, thereby avoiding the brush from contaminating surrounding items and the brush from being contaminated by surrounding objects. In addition, the applicability of the tool can be improved by inserting an eyebrow pencil into the limiting cylinder. Attached Figure Description

[0014] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0015] A twistable, retractable pen, such as Figures 1-3 As shown, the device includes a pen holder 1 and a pen cap 2 that is snapped onto the pen holder 1. A positioning cylinder 3 is fixedly connected inside the pen holder 1. A threaded rod 4 that moves within the positioning cylinder 3 is provided. A limiting post 5 that is fixedly connected to the threaded rod 4 to move the threaded rod 4 within the positioning cylinder 3 is used to extend and retract the threaded rod 4. A brush 6 is fixedly connected to the other end of the limiting post 5. A pen tip 7 is snapped onto the positioning cylinder 3. Several guide blocks 8 that are adapted to the threaded rod 4 are fixedly connected inside the positioning cylinder 3. The combination of several guide blocks 8 is equivalent to a non-complete internal thread fixedly connected inside the positioning cylinder 3, thereby reducing the contact area between the internal thread and the threaded rod 4, making it easier to rotate the pen tip 7.

[0016] like Figures 1-3As shown, when installing the pen, first take out the pen holder 1, then insert the positioning cylinder 3 into the pen holder 1 to fix it. Next, take out the threaded rod 4 and rotate it into the positioning cylinder 3. Then take out the pen tip 7, put the pen tip 7 on the limiting post 5 and the brush 6, and press it firmly to make the pen tip 7 snap into the pen holder 1. Finally, put on the pen cap 2. When using it, remove the pen cap 2, and then rotate the pen tip 7. The pen tip 7 will drive the limiting post 5 to rotate, and then the limiting post 5 will drive the threaded rod 4 to rotate. At this point, the brush 6 will extend from the pen tip 7 to the outside, and it can then be used. After use, first clean the brush 6, and then rotate the pen tip 7 in the opposite direction to drive the threaded rod 4 to rotate through the limiting post 5, which will drive the brush 6 into the pen tip 7. At this time, the water stains remaining on the brush 6 due to cleaning will also be squeezed out by the pen tip 7. When the brush 6 is completely inside the pen tip 7, you can stop rotating and then put on the pen cap 2 to prevent the brush 6 from contaminating surrounding items and from being contaminated by surrounding objects.

[0017] like Figures 2-3 As shown, the limiting post 5 is a hexagonal prism, and the pen tip 7 is placed in the inlet and adapted to the limiting post 5, which makes it easier to put the pen tip 7 on the limiting post 5 and ensures that the pen tip 7 can drive the limiting post 5 to rotate.

[0018] like Figures 2-3 As shown, a limiting block 9 is fixedly connected to the threaded rod 4. The extension length of the limiting block 9 exceeds the major diameter of the thread of the threaded rod 4, so as to prevent the pen tip 7 from rotating excessively, which would cause the thread on the threaded rod 4 to disengage from the guide block 8.

[0019] like Figures 2-3 As shown, a hemispherical block 10 is fixedly connected to the end of the threaded rod 4 away from the limiting block 9, which makes it more convenient and faster to insert the threaded rod 4 into the positioning cylinder 3.

[0020] like Figure 1 , Figure 2 , Figure 4 As shown, a tail cap 11 is snapped onto the pen holder 1, and a limiting tube 12 is snapped onto the tail cap 11. The limiting tube 12 has elastic deformation capability. An eyebrow pencil can be inserted into the limiting tube 12, and then the limiting tube 12 is inserted into the tail cap 11. The tail cap 11 is then inserted into the pen holder 1 and snapped onto the pen holder 1. If you want to use it, you can pull out the tail cap 11 and then pull out the limiting tube 12 from the tail cap 11. At this time, the eyebrow pencil can be used in an emergency, thereby improving the applicability of the tool pen.

[0021] Working principle: When installing the pen tool, first take the pen holder 1, then insert the positioning cylinder 3 into the pen holder 1 and fix it. Next, take the threaded rod 4 and rotate it into the positioning cylinder 3. Then take the pen tip 7, put the pen tip 7 on the limiting post 5 and the brush 6 and press it firmly to make the pen tip 7 snap into the pen holder 1. Finally, put the pen cap 2 on.

[0022] When in use, remove the pen cap 2, and then rotate the pen tip 7. The pen tip 7 will drive the limiting post 5 to rotate, and then the limiting post 5 will drive the threaded rod 4 to rotate. At this time, the brush 6 will extend from the pen tip 7 to the outside, and then it can be used.

[0023] After use, first clean the brush 6, then rotate the pen head 7 in the opposite direction to drive the threaded rod 4 to rotate through the limiting post 5, so that the brush 6 enters the pen head 7. At this time, the water stains remaining on the brush 6 due to cleaning will also be squeezed out by the pen head 7. When the brush 6 is completely inside the pen head 7, you can stop rotating and then put on the pen cap 2 to prevent the brush 6 from contaminating surrounding items and from being contaminated by surrounding objects.

[0024] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
