Specifically, as shown in fig. 2, the pen body 1 has a generally cylindrical shape, and the diameter of the cylinder decreases from one end to the other end. A first thread 11 is arranged on a shaft section with a larger diameter on the pen body 1, a convex ring is derived from one side of the first thread 11 along the circumferential direction of the pen body 1, and a limiting groove 12 is formed on the end surface of the convex ring, which is close to the first thread 11; the pen body 1 is provided with a finger hole 13 from one end with a larger diameter to one end with a smaller diameter, and the caliber of the finger hole 13 gradually becomes smaller towards the direction close to the pen point so as to facilitate the insertion of the finger. As shown in fig. 3, the overall shape of the refill holder 2 is similar to a cylinder, the diameter of one end of the refill holder 2 is gradually reduced, and the end is provided with a avoiding hole 23 for passing through the pen point of the refill 3; the other end of the refill sleeve 2 is sleeved on the shaft section with the smaller diameter of the pen body 1, a cavity is formed by surrounding the refill sleeve 2 and the pen body 1 for installing the refill 3, a second thread 21 is formed in the inner wall of the refill sleeve 2, the second thread 21 is matched with the first thread 11, after the first thread 11 is matched with the second thread 21, the end part of the refill sleeve 2 is located in the limit groove 12, and the groove wall of the limit groove 12 can limit the end part of the refill sleeve 2 so as to prevent the refill sleeve 2 from deforming.

In this embodiment, the diameter of the finger hole 13 may be increased, or a plurality of finger holes may be connected in series, so as to facilitate the insertion of a plurality of fingers at the same time.

It is understood that the pen tip in this embodiment may be a conventional marking pen tip, a neutral pen tip, a pen tip, or may be an unusual ball-point pen tip, a writing brush tip, a mark pen tip, or the like. A spiral ink-absorbing sponge tube can be assembled between the cavity formed by the matching of the pen refill sleeve 2 and the pen body 1; or can be assembled into a spiral neutral pen refill or a ball-point pen refill; the pen can also be assembled into a flexible pen ink container, and the pen ink container is connected with a pen point at the moment. For example, in one embodiment, the pen head is configured as a pen head, and the pen head can be directly used after being matched with the avoiding hole 23, and a flexible pen ink container can be assembled in a cavity formed by matching the pen core sleeve 2 with the pen body 1, the pen head and the pen ink container are connected through a through hole on the pen core sleeve 2, and at the moment, the design configuration is modified into a pen. In summary, the pen point of the type of the configuration pen can be any type of pen point, and according to different structures in the pen, a spiral structure pen core, a flexible ink liner, or an ink absorbing sponge can be selectively arranged in a cavity formed by matching the pen core sleeve 2 with the pen body 1.
