The rotating shaft outer cylinder 2 is provided with two or more sliding blocks 21 and adjusting slopes 22.

The inner rod 12 is sleeved in the rear barrel body 31, the rotary shaft outer barrel 2 is movably sleeved between the nib shell 11 and the inner rod 12 and is partially accommodated in the rear barrel body 31, the refill 42 is positioned in the rotary shaft assembly and the rear barrel, and the return spring 41 is positioned between the refill 42 and the refill hole 111.

The extended inner post 312 and the stable friction limiting inner protrusion 311 form a sliding chamber in combination. The slide block 21 is located in the slide chamber and slides up and down.

The adjustment ramp 22 is only movable up and down and cannot be rotated by the slide block 21.

The shifting block 121 can be freely rotated and freely moved into and out of the sliding chamber.

The change in position of the misalignment block 121, effected by the return spring, exists in two states.

Thirdly, the dislocation block 121 is positioned in the sliding cavity, and the pen core is in a withdrawing state at the moment.

And fourthly, the dislocation block 121 is positioned outside the sliding chamber, particularly the usage slope 1211 and the inner column slope 3121 are in a contact state, and the pen core is in an exposed state at the moment.

The state of the dislocation block 121 is switched, and after the pushing of the regulating slope 22 is adjusted to make the dislocation block contact with the using slope 1211 or the detaching slope 1212, the dislocation block 121 rotates with a small amplitude, so that the using slope 1211 or the detaching slope 1212 contacts with the inner column slope 3121, further rotation of the dislocation block 121 is caused, and the dislocation block enters or leaves the sliding chamber.

In order to ensure that the rotating shaft assembly cannot be separated from the stable friction limiting inner convex end of the rear pen container body and ensure that the whole structure is more stable in use, the inner diameter of the stable friction limiting inner convex 311 is smaller than the distance between the surface of the dislocation block 121 and the axis of the inner rod, namely, the dislocation block 121 cannot pass through the stable friction limiting inner convex 311. The inner diameter of the inner steady friction limiting protrusion 311 is smaller than the distance between the surface of the sliding block 21 and the axis of the inner rod, that is, the sliding block 21 cannot pass through the inner steady friction limiting protrusion 311.

The inner diameter of the soft rubber sleeve 43 corresponds to the outer diameter of the limiting slope 23, so that the soft rubber sleeve is convenient to sleeve. Therefore, the limiting slope 23 can play a limiting role to prevent the soft rubber sleeve 43 from moving towards the end close to the regulating slope 22. However, the soft rubber sleeve 43 is easily separated from the end of the limit slope 23, so that the pen point shell 11 needs to be further fixed, and the outer diameter of the pen point shell 11 is larger than the inner diameter of the end opening of the soft rubber sleeve 43 close to the end of the pen point shell 11.

In order to ensure that the matching between the rotating shaft outer cylinder and the rear pen container can be more stable and reduce unnecessary shaking, the length of the stable friction limiting inner protrusion 311 is at least longer than 1 mm. The longer the length of the stable friction limiting inner protrusion 311 is, the more stable the connection and the matching of the rear pen container 3 and the rotating shaft assembly are, and the smaller the shaking amplitude is.

In order to realize the pen core suitable for different specifications, a plurality of cover bodies 32 with different lengths can be adopted to meet the installation requirements of the pen cores with different lengths. When the length of the pen core is different, the installation requirement can be met by replacing the matched cover body 32 with the corresponding length.
