Compared with the prior art, the quick-matching anti-falling pen adopting the technical scheme has the following beneficial effects:

1. compared with the prior gel ink pen shell, the gel ink pen has the advantages that the anti-falling effect is improved, due to the structural design of the pen shell, the pen core can be retracted into the pen shell by the elastic force of the return spring as long as the sum of the external force and the elastic force of the return spring is larger than the clamping force between the buckle extending inner table and the matched using hole, so that the gel ink pen has the technical effects of preventing falling and protecting the pen core.

2. The use method is optimized, so that the refill can be retracted and exposed by one hand, the use state and the unused state can be switched when the normal pen holding posture is kept, the writing holding posture is not required to be changed, and the refill is switched back to the writing holding posture after being exposed through another gesture deformation operation; the increased efficiency and speed of use simplifies the flow of operations to switch between pen use and non-use states.

3. The writing gesture correction can prevent fingers from excessively approaching the pen point, so that the vision is blocked, the writing is not facilitated, and the writing gesture excessively approaching the pen point is held, so that humpback, single shoulder height and/or myopia are generally caused, because the excessively approaching fingers can block the vision, people need to use abnormal sitting postures to match, the writing content is seen, and the writing force is convenient; in addition, the person can unconsciously lean forward, and the eyes can be excessively close to the writing position, so that diseases such as myopia, single shoulder height and/or humpback and the like are caused; under normal conditions, people do not know the correct distance between the correct holding gesture and the pen point, and even if the correct distance between the correct holding gesture and the pen point is known, the problem is caused because the user can write too carefully and unconsciously write the holding gesture too close to the pen point; and people who are used to the bad holding gesture can be more likely to have the situation; the structural design provided by the invention can avoid the bad holding gesture, and once the force point touches the designed warning line, the pen core can be automatically retracted-! The designed guard line depends on the distance between the inner pen holder and the front pen holder.

4. Three problems of writing gesture correction, anti-falling and quick operation are realized by using a simple structure combination, and the three problems can be only singly presented on a pen tool, and the structure of the invention realizes integration, and the unexpected technical effect is achieved by using the simple and ingenious structure combination, thereby solving the technical problems; if the writing gesture correction is realized by a complex mechanical linkage principle, however, the cost is very expensive, so that the writing gesture correction is not practical, and the writing gesture correction device is simpler and more practical in structure than a traditional pressing pen.

The inner pen holder 1 is sleeved in the front pen holder 2 in a sliding way. The front pen holder 2 is in threaded fit connection with the rear pen holder 3. The front end of the rear pen container 3 is provided with a matched hole 32, and the rear end is provided with a fixed clamping seat 31. The pen core 4 is arranged in a pen shell formed by combining the inner pen holder 1, the front pen holder 2 and the rear pen holder 3, and the tail end of the pen core 4 is fixed in the fixing clamping seat 31. The reset spring 5 is positioned in the inner penholder 1, and is particularly positioned between the inner penholder 1 and the pen core 4. The front end of the front pen holder 2 is provided with a supporting inner ring 21. The inner pen holder 1 is provided with a supporting ring protrusion 13 and a buckle extending inner table 16. The above-mentioned snap-extending inner stand 16 and the mating hole 32 are engaged with each other, and when the snap-extending inner stand 16 enters the mating hole 32, a snap force is generated, so that the snap-extending inner stand is not easy to leave the mating hole 32.

If the wear-resistant soft sleeve 162 is provided, the fixing inner protruding point 322 and/or the fixing inner concave ring 323 can be engaged with the wear-resistant soft sleeve 162 instead of the hole 32. The slope of the matching landslide 321 can help the buckle to extend the inner table 16 and the outer convex ring 1633 into the matched hole 32 quickly, so that the matching landslide can be clamped with the matched hole 32, the fixed inner convex point 322 and/or the fixed inner concave ring 323. Further increases the clamping effect, thereby reducing the generated friction area, improving the clamping tension and being more beneficial to clamping. Through the cooperation between outer convex ring 163 and fixed inner convex point 322 and/or fixed concave ring 323, can realize more stable block mode, then block through the form of buckle, but use the sense of setback strong. The wear-resistant soft sleeve 162 and the matched hole 32 are adopted, or the clamping of the clamping extension inner platform 16 and the matched hole 32 is realized by adopting a friction clamping mode, so that no pause feeling is realized, but the matched friction force must overcome the elasticity continuously generated by the reset spring 5, so that the clamping state failure is avoided. If the wear-resistant soft sleeve 162 is sleeved on the outer convex ring 1633, the shock feeling can be reduced, and meanwhile, the wear-resistant soft sleeve is clamped in a buckle mode, so that the wear-resistant soft sleeve is stable and has small shock feeling.
