The pen control mode has the following problems:

1. beginners often need to go to practice through spending a large amount of time, just can make the characters write and become neatly and pleasing to the eye, and the drawing line type becomes accurate. Meanwhile, because the pen moving accuracy is in a relatively fuzzy area, the spirit of the pen moving needs to be highly focused on controlling the pen point, and the writing process is very troublesome.

2. In some special environments and places, inconvenience is easily brought by using a traditional pen holding mode. Especially in winter, cold storage and other low temperature environments, a user must take off the gloves for writing, otherwise, the movement track of the pen point is difficult to control, and characters are written neatly; hands are easily numb by freezing after the gloves are taken off for writing for a while, so that writing is more difficult, and the hands are exposed to a low-temperature environment for a long time and risk of being frostbitten.

3. For some special people, especially for the people with disabled fingers, the pen cannot be held.

Based on this, the stylus pen is invented. A finger pen, also called finger pen, fingertip pen or fingertip pen, is to cover a finger with the pen for writing. However, until now, the stylus has not been popularized and used. The inventor researches related patents of the existing finger pens and finds that the degree of fit and matching between the pen type designed by the existing finger pen and the finger is not high when writing, and the pen type is an important reason for leading the field of the finger pen to be still in a silent state.

The embodiment provides a design method of a stylus, which aims to improve and enhance the practicability of the stylus and enable the stylus to be widely popularized. In the embodiment, a sleeve structure is adopted as a pen body for fixing the finger pen on the finger, the pen head is arranged at the front end outside the sleeve structure, the inside of the sleeve structure is used as a finger hole for accommodating the finger, and the finger hole is designed into a space with the inner diameter gradually increasing from the bottom to the orifice so as to be attached to the finger; further, the length of the opening of the finger hole from the bottom is designed to be longer on the dorsal side than on the ventral side, and the ventral side is not longer than the first joint of the finger, or more, the second joint and even the third joint are possible, so that the finger can be freely bent when writing. By adopting the design method, the stylus and the fingers can be more attached, the following degree of the stylus and the fingers in writing is improved, free bending of the fingers in writing is not influenced under the premise, and the writing fluency is ensured. The finger pen based on the design method has the advantages that the relative position is in the shape of long back side and short palm side, the following degree and the writing smoothness of the finger pen and fingers can be considered, and the practicability of the finger pen can be effectively improved.

Based on the design method, the present embodiment provides a finger pen, as shown in fig. 1-8, which includes a pen body 1, a finger hole 2 for placing a finger is provided on the pen body 1, an opening of the finger hole 2 has a back side and a palm side opposite to each other, and a connecting line of the back side and the palm side forms an included angle with an extending direction of the finger hole 2.

In this embodiment, the finger hole 2 is mainly used for placing a finger, and it only needs to be able to achieve the purpose of matching with the finger, so the specific shape of the finger hole 2 is not limited, and the aperture transition form is designed as one or a combination of a straight line, a curved line and a broken line on the sleeve structure linking the left and right side parts of the dorsal side and the palmar side. Any transition is practically feasible on the basis of satisfying the long dorsal side and the short palmar side of the finger hole. The inside of the finger hole can be in a regular shape such as a cylinder shape, a cone shape, a square shape, a curved tube shape and the like, and can also be in an irregular shape such as a counter bore shape, a flask shape, a threaded hole shape and the like, but certain stability is at least required to be ensured after the finger is matched with the finger hole 2. The extending direction of the finger hole 2 refers to the arrangement direction of an infinite number of sections of the finger hole 2, for example, in the cylindrical finger hole 2, the extending direction refers to the axis of the cylinder, and in the curved-tube-shaped finger hole 2, the extending direction refers to the Z shape assuming that the curved-tube-shaped finger hole 2 is Z-shaped.

The pen body 1 is generally of a similar revolving body structure with a large end and a small end, taking the direction of the drawing as an example, and referring to fig. 1 specifically, the pen body 1 is grooved inwards from the large end to form a finger hole 2, the section of the finger hole 2 is of an approximately elliptical configuration to be adapted to fingers, two sides of the large end of the pen body 1 are the back side and the palm side, and the connecting line of the back side and the palm side forms an included angle with the extending direction of the finger hole 2; due to the existence of the included angle, the length of the inner wall of the finger hole 2 in the extending direction of the finger hole 2 is gradually increased from bottom to top. When writing, the longer side of the inner wall of the groove corresponds to the back of the finger, the contact area between the inner wall of the groove and the back of the finger is increased, and the pain of the finger head during writing is reduced. Meanwhile, the design that the surface of the entrance of the finger hole 2 is made into an inclined surface can shorten the depth of the shorter surface in the finger hole 2, which is beneficial to increasing the bending range of the finger head during writing and further improving the comfort during writing; in addition, because the ink absorption sponge tube or the pen core 3 is just positioned on the finger back of the finger pen, the design that the surface where the inlet of the finger hole 2 is arranged to be the inclined surface or the curved surface can prolong the whole length capable of accommodating the ink absorption sponge tube or the pen core 3, which is beneficial to increasing the ink bearing capacity of the ink absorption sponge tube or the pen core 3 and further beneficial to prolonging the service life after replacing the pen core 3 or filling ink into the ink absorption sponge tube each time.

It is understood that the pen tip 5 in the present embodiment may be a common marking pen tip 5, a gel ink pen tip 5, or a pen tip 5, or may be an unusual pen tip 5, a writing brush tip 5, or a mark pen tip 5. An ink absorbing sponge tube can be assembled between the cavity formed by matching the pen point fixing piece 6 and the pen body 1; can also be assembled into a gel ink refill tube or a ball-point pen refill tube; it can also be assembled into a flexible ink reservoir of a pen, which is connected to the pen nib 5. For example, in one embodiment, the pen point 5 is a pen point 5, and the pen point 5 can be directly used after being matched with the through hole, a flexible pen ink container can be assembled in the pen cavity 4 formed by matching the pen point fixing member 6 and the pen body 1, the pen point 5 and the pen ink container are connected through the through hole on the pen point fixing member 6, and the design configuration can be directly converted into a pen for use. In short, the pen tip 5 of the present embodiment may be of any type, and a refill tube, a flexible ink container, an ink absorbing sponge, or the like may be selectively inserted into the cavity according to the type of the pen tip 5.

It should be noted that, in the sleeve structure, the creative design is preferably combined on the pen body at the left and right side parts of the back side and the palm side. The scheme is additionally provided with a text creation type design part, and the combination of the text creation type design part and the text creation is an effective mode for the stationery to attract users. In this embodiment, the surface of the finger hole 2 may be a plane surface as shown in fig. 3, a curved surface as shown in fig. 4 or 5, or a wing-shaped creative shape as shown in fig. 7.

It will be understood that when the face of the finger hole 2 at which the aperture is located is curved, the curved face may be concave inwardly, as shown in fig. 4 or 5, or may be convex outwardly.

It is understood that when the surface of the finger hole 2 is an accordion surface, the accordion surface may be shaped like a wing-shaped accordion line, or may be a wave shape, or a flower-shaped polygon. Meanwhile, the hollow-out form or the relief form of various types can be combined. On the premise of meeting basic functions, the pen body surfaces at two sides of the finger hole can have N different possible shapes.

It is understood that when the face of the finger hole 2 is a slant face, the slant angle of the face of the finger hole 2 at the entrance may not be limited, and the contact area between the finger hole 2 and the finger can be increased as long as the connecting line between the back side and the palm side forms an angle with the extending direction of the finger hole 2. Meanwhile, as the included angle is smaller, the total length of the ink absorbing sponge tube or the pen core 3 can be longer, and the depth of the shorter side in the finger hole 2 is shorter. Preferably, the included angle is about 45 degrees to 60 degrees with the plane along the trend of the finger hole 2, and the finger pen integrally presents a relatively beautiful appearance.

In some possible embodiments, the finger hole 2 has a gradually increasing cross-sectional area extending from the bottom of the groove to the direction of the opening. This is to adapt the appearance of the finger.

Further optimizing, the inner side groove edge of the hole is set to be a chamfer structure. In the writing process, because the finger waves, the finger and the orifice of the finger hole 2 can be frequently contacted and rubbed, and the inner side groove edge is set to be of a chamfer structure, so that the contact area between the groove edge and the finger is increased, stress concentration is avoided, and the discomfort of the finger is reduced.

In some possible embodiments, in order to prevent the evaporation of the ink at the nib 5, the smaller end of the body 1 is provided with a cap 7.

In some possible embodiments, a vent hole which penetrates through the pen body and the flexible sheath and is communicated with the outside is arranged at the bottom of the finger hole, and the vent hole is used for exhausting air when the pen body is sleeved on a finger.

A plurality of vent holes 13 are formed in the pen body 1, and the finger holes 2 are communicated with the space outside the pen body 1 through the vent holes 13. The purpose of the ventilation hole 13 is to increase the ventilation inside the finger hole 2, to make it easier for the finger to enter the finger hole 2, and to prevent the finger hole 2 from being inflated during writing.

In some possible embodiments, a flexible sheath is provided inside the finger hole to reduce the discomfort caused by the difference in finger shape; and the inner surface of the flexible sheath is made of skin-friendly materials, so that the finger holes are firmly attached to the fingers. The flexible sheath 11 is shaped to fit into the finger hole 2. The flexible sheath 11 is arranged to protect the fingers and improve the writing comfort; on the other hand, the friction force of the finger relative to the finger hole 2 is increased, so that the matching between the finger and the finger hole 2 is more stable, and the phenomenon that the finger pen falls off from the finger during writing is avoided.

Further optimized, the flexible sheath 11 is provided with a vent 12. The ventilation holes 12 may be provided to correspond to the positions of the ventilation holes 13 of the pen body 1, so that the uncomfortable feeling due to the air tightness can be reduced in the case of using the flexible sheath 11.
