This invention not only improves the wear resistance of ballpoint pens, but also offers advantages such as longer writing time, longer service life, higher stability, and ease of use. However, its drawback is that it does not help users reduce incorrect usage methods. Utility Model Content

[0003] The present invention aims to overcome the shortcomings of existing technologies that fail to help users reduce incorrect usage methods, and provides a wear-resistant ballpoint pen structure that can help users reduce incorrect usage methods.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A wear-resistant ballpoint pen structure includes:

[0006] The lower pen casing is placed at the bottom of the ballpoint pen, and the interior of the lower pen casing is hollow;

[0007] The upper pen shell is placed on the upper end face of the lower pen shell. The upper pen shell and the upper end face of the lower pen shell are threaded together. The interior of the upper pen shell is hollow. The interior of the upper pen shell and the interior of the lower pen shell are coaxial.

[0008] A misaligned shell is placed on the upper end surface of the upper pen shell and is misaligned with the upper pen shell. The upper pen shell and the misaligned shell are integrally formed, and the interior of the misaligned shell is hollow.

[0009] The pen refill passes through the misaligned shell, the upper pen shell, and the lower pen shell at its lower end and is placed below the lower pen shell.

[0010] A telescopic component is placed on the upper surface of the pen refill and in contact with the upper surface of the pen refill. The lower end of the telescopic component is placed inside the misalignment shell, and the upper end of the telescopic component is placed above the misalignment shell.

[0011] The pressing head is fitted over the upper end of the telescopic component. The pressing head is positioned above the misaligned shell, and the inner side of the pressing head is engaged with the telescopic component.

[0012] A spring is placed inside the lower pen housing, the spring surrounds the lower part of the pen refill, and the spring engages with the pen refill;

[0013] A rubber sleeve is fitted over the pressing head, and the rubber sleeve is fixedly connected to the outer side of the pressing head.

[0014] During installation, place the spring-loaded pen refill into the lower pen shell, then install the upper pen shell, ensuring the refill is pressed against the telescopic mechanism before tightening. When using, place your thumb and forefinger at the misalignment between the upper and lower pen shells, then hold the outer side of the lower pen shell to accurately position the pen. To extend or retract the pen, press the press head in conjunction with the telescopic mechanism and spring. This allows for easy retraction and extension of the pen refill, extending the lifespan of the ballpoint pen. The rubber sleeve on the outer side of the press head significantly reduces the urge to bite the pen tip, thus helping users avoid incorrect usage.

[0015] Preferably, the lower pen shell is provided with a second rubber sleeve, which surrounds the lower pen shell. The inner side of the second rubber sleeve is fixedly connected to the outer side of the lower pen shell. The second rubber sleeve has two symmetrically distributed grip grooves, and the position of the grip grooves is at a 90-degree angle to the direction of the offset shell. The second rubber sleeve effectively protects the lower pen shell, and the grip grooves allow the fingers to grip the pen in a precise position.

[0016] Preferably, the misaligned shell is provided with a guide groove, which is funnel-shaped. The upper end of the guide groove is connected and communicates with the interior of the misaligned shell, and the lower end of the guide groove is connected and communicates with the interior of the upper pen shell. The guide groove facilitates the installation of the pen refill.

[0017] Preferably, a limiting block is provided inside the misalignment shell, the limiting block is placed on the side of the telescopic member, and the limiting block is fixedly connected to the inner side of the misalignment shell. The limiting block facilitates limiting the position of the telescopic member that may be misaligned.

[0018] Preferably, the upper surface of the misaligned shell has a through hole, which is coaxial with the interior of the upper pen shell. The upper end of the telescopic component passes through the through hole and is positioned above the misaligned shell. The position of the through hole ensures that the telescopic component is coaxial with the pen refill.

[0019] Preferably, the pen refill has a retaining ring, which surrounds the lower part of the pen refill and is integrally formed with it. The spring is located on the lower end face of the retaining ring, and the spring is engaged with the pen refill through the cooperation of the retaining ring and the inner side of the lower pen shell. The retaining ring can hold the spring in place, allowing the refill to extend and retract with the misalignment component.

[0020] Preferably, the rubber sleeve has several plastic particles evenly distributed on its outer surface, and these particles are fixedly connected to the outer surface of the rubber sleeve. The plastic particles can significantly reduce the user's habit of biting the pen tip.

[0021] Preferably, the telescopic component is provided with a second retaining ring, which surrounds the outer surface of the telescopic component and is integrally formed with the telescopic component. The pressing head is engaged with the telescopic component through the second retaining ring. The second retaining ring facilitates the installation of the pressing head.

[0022] The beneficial effects of this utility model are: it helps users reduce incorrect usage methods; the second rubber sleeve protects the lower pen shell; the grip groove allows fingers to hold the pen in the correct position; the guide groove facilitates the installation of the pen refill; the limiting block facilitates the positioning of the telescopic component that is offset; the through hole position allows the telescopic component and the pen refill to be coaxial; the first retaining ring can hold the spring in place before it can cooperate with the offset component to extend and retract the pen refill; the plastic particles can further reduce the user's habit of biting the pen tip; the second retaining ring facilitates the installation of the pressing head.
