[0002] With the continuous advancement of technology, electronic pens have been widely used in education, office work, design, and many other fields. As a digital device that simulates traditional writing tools, the design and functions of electronic pens are constantly being optimized. However, the center of gravity distribution of electronic pens is not always reasonable, which may require users to exert extra force to maintain the stability of the pen during writing.

[0003] Chinese utility model patent (CN217543814U) discloses an electronic pen and its tip. The pen tip includes a pen head and a pen barrel, with a pen core electrically connected to the pen head inside the pen barrel. The pen head is a hollow structure surrounded by a flocked layer, which is a conductor and electrically connected to the pen core. Because the pen head surface is covered with fiber fluff, its surface smoothness is significantly reduced, breaking the conditions for adhesion and greatly reducing friction between contact surfaces. However, in actual use, the fixed center of gravity of this electronic pen cannot meet the needs of different groups. For example, some people prefer electronic pens with the center of gravity closer to the pen head, while others prefer those with the center of gravity closer to the pen tail, thus limiting the pen's functionality.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0029] In the embodiments of this utility model, the pen tube design with adjustable counterweight can effectively adjust the center of gravity of the pen, flexibly adapt to the writing habits of different users. Several counterweight slots are evenly provided at both ends of the pen tube. People can install different numbers of counterweight blocks at both ends of the pen tube according to their needs, so as to realize personalized adjustment of the center of gravity and meet the needs of more people.

[0030] A dual-pen tip component 3 is also provided, both ends of which can be used as pen tips 31 of a stylus. When one pen tip 31 is damaged after long-term use, people can flip the component and reinstall it back into the pen tube to continue using it, thus enabling portable replacement of the pen tip 31.

[0031] Please see Figures 1-2In this embodiment of the invention, a pen tube with adjustable counterweight includes a pen tube body 1. One end of the pen tube body 1 has several first counterweight grooves 11 and corresponding first counterweight blocks 12. The other end of the pen tube body 1 has several second counterweight grooves 13 and corresponding second counterweight blocks 14. The first counterweight grooves 11 are located near the end of the pen tube where the pen tip 31 is installed, and the second counterweight grooves 13 are located near the end of the pen tube at the tail end. Specifically, the first counterweight blocks 12 and the second counterweight blocks 14 are both metal cylinders of equal mass, with each block weighing 2g.

[0032] like Figure 2 As shown, two first counterweight slots 11 are provided at the front end of the pen tube body 1, and two second counterweight slots 13 are provided at the rear end of the pen tube body 1. Users can insert counterweight blocks into the first counterweight slots 11 or the second counterweight slots 13 as needed to adjust the pen's center of gravity. The working principle of this embodiment is as follows: when the user adds a first counterweight block 12 at the front end, the center of gravity moves towards the pen tip 31, which is suitable for users who hold the pen forward; conversely, adding a second counterweight block 14 at the rear end shifts the center of gravity backward, suitable for users who hold the pen backward. By varying the number of counterweight blocks at the front and rear, for example, two at the front or two at the rear, continuous adjustment of the center of gravity can be achieved.

[0033] Further as Figures 1-6 As shown in the embodiment of this utility model, the pen tube is provided with a first mounting plate 15 and a second mounting plate 16. The first mounting plate 15 is detachably mounted on the first counterweight groove 11 to cover the first counterweight groove 11, and the second mounting plate 16 is detachably mounted on the second counterweight groove 13 to cover the second counterweight groove 13. A through groove 17 is provided at one end of the pen tube body 1 near the pen tip 31 to expose the first counterweight groove 11. Sliding grooves 171 are respectively provided on both sides of the through groove 17. The two sides of the first mounting plate 15 are respectively provided with sliding grooves 171. A slider 151 is provided for inserting into the slot 171, so that the first mounting plate 15 can be slidably installed in the through slot 17. The end of the through slot 17 is provided with a magnetic attraction structure for magnetically connecting the first mounting plate 15. The magnetic attraction structure includes a first magnetic layer 21 disposed at the end of the through slot 17 and a second magnetic layer 22 disposed at the end of the first mounting plate 15. When the first mounting plate 15 is inserted into the through slot 17, the first magnetic layer 21 and the second magnetic layer 22 attract each other to prevent the first mounting plate 15 from sliding out of the through slot 17.

[0034] Specifically, the first magnetic layer 21 and the second magnetic layer 22 can be installed by magnetic bonding. The magnetic structure enables the first mounting plate 15 to "lock with a push," avoiding the problem of easy breakage of traditional clips. The working principle of this embodiment is as follows: the first mounting plate 15 is pushed in along the slide groove 171 until it completely covers the first counterweight groove 11. At this time, the first magnetic layer 21 and the second magnetic layer 22 attract each other to prevent the first mounting plate 15 from accidentally slipping off. When it is necessary to remove the first mounting plate 15, a force greater than the magnetic attraction force can be applied to remove it.

[0035] In another embodiment of the present invention, the magnetic structure includes a first magnetic layer 21 disposed at the end of the through groove 17. The first magnetic layer 21 can be installed by means of magnetic bonding. The material of the second mounting plate 16 can be metal, which can also achieve the effect of magnetic connection with the first magnetic layer 21. The metal material of the second mounting plate 16 includes, but is not limited to, iron, nickel or iron-containing alloys.

[0036] Further as Figures 1-2 As shown in this embodiment of the invention, one end of the second mounting plate 16 is hinged to the surface of the pen tube near the second counterweight groove 13. When the second mounting plate 16 is opened outwards, the second counterweight groove 13 is exposed. Specifically, the second mounting plate 16 can be hinged to the tail of the pen tube by means of a hinge (not shown in the figure). A rubber sealing ring (not shown in the figure) is provided on the inner side of the second mounting plate 16, which is interference-fitted with the edge of the counterweight groove when closed. The second mounting plate 16 is provided with a handle for easy locking. Working principle of this embodiment: The user presses the second mounting plate 16 with their finger to rotate and open it around the hinge axis to expose the second counterweight groove 13. At this time, the user can place the second counterweight 14 into the second counterweight groove 13, and then flip the second mounting plate 16 to close it.

[0037] Further as Figures 1-2 As shown in this embodiment of the invention, the surface of the pen tube body 1 at one end for mounting the pen tip 31 is provided with a first anti-slip texture 18, and the surface of the first mounting plate 15 is provided with a second anti-slip texture 19. Specifically, the surface of the front end of the pen tube is processed with a diamond-shaped grid pattern of the first anti-slip texture 18 and the second anti-slip texture 19, which can increase friction, make it easier for people to grip, improve the feel, and prevent slipping during use, making it suitable for users with sweaty hands.

[0038] Further as Figures 1-5As shown in the embodiment of this utility model, a stylus includes the aforementioned weight-adjustable pen tube. The stylus is equipped with a dual-pen tip component 3, with pen tips 31 at both ends for the stylus. A thread 32 is provided at the connection point of the two pen tips 31, and the dual pen tips are threadedly installed at the end of the pen tube where a first weight groove 11 is provided. Specifically, a standard thread 32 is provided in the middle of the dual-pen tip component 3, and an internal threaded hole 41 matching the threaded portion of the dual-pen tip component 3 is provided at the front end of the pen tube. The working principle of this embodiment is as follows: when one end of the pen tip 31 is damaged after long-term use, it can be easily flipped 180° and reinstalled back into the pen tube for continued use, enabling portable replacement of the pen tip 31.

[0039] The working principle of this utility model is as follows: when the user installs the first counterweight block 12 in the first counterweight slot 11, the center of gravity moves towards the pen tip, which can be adapted to users who hold the pen in a forward position; conversely, when the second counterweight block 14 is added in the second counterweight slot 13, the center of gravity moves backward to be adapted to users who hold the pen in a backward position. Users can install different numbers of counterweight blocks at both ends of the pen tube according to their usage needs to achieve personalized adjustment of the center of gravity.
