Abstract

The utility model discloses a pen holding device which can be sheathed on a pen holder of a hard pen. The utility model is composed of a sleeve body; the sleeve body is provided with three finger contacting surfaces, each of which forms a triangular-prism-shaped body; the center of the sleeve body is provided with a circular, triangular, or polygon-shaped through hole; the inner wall of the through hole is axially provided with a groove which has the functions of elasticity and contraction and can move on the pen holder, the groove can also be quietly and tightly sheathed on the pen holder. The utility model has the advantages of simple structure, good hand-feeling, and no tiredness of fingers for long-time use. The utility model can make users keep correct pen holding postures with three fingers and has definite health care effect.

Description

Three refer to write device

The utility model relates to the write stationery of usefulness of a kind of children of being primarily aimed at, and specifically, relates to the stationery of the correct writing posture of a kind of children of cultivation.

At present, the instrument of people's writing words is mainly based on hard-tipped pen, and as pencil, pen, ball pen etc., whether good-looking word write to such an extent that with posture that write much relations are arranged, and the cultivation of writing posture must form a good habit from handwriting practicing.

Common hard-tipped pen, the penholder overwhelming majority is cylinder or hexagonal prism etc., can not help the children that begin to practise writing to form correct writing posture, because writing posture incorrectly tends to bring the side head, bad habit such as bend over.Can have influence on children's the ability of writing, learning ability like this, influence growing up healthy and sound of children, so the teacher and the head of a family often use educational method by doing and illustrating, though also can play a role, but because children's autocontrol force is relatively poor, so effect is not very desirable.The long-time penholder finger of cylinder or hexagonal prism that uses is tired easily.

The purpose of this utility model provide a kind of user of making particularly children when writing, keep correct writing posture, and write the tireless device of writing for a long time.

The purpose of this utility model realizes by following scheme, a kind of device of writing, constitute by a body, it is characterized in that the body central shaft is to having the through hole that can match with penholder, the cover body profile is column, and three finger contact planes are arranged, and angle is respectively A angle, B angle, C angle between each plane, and meet the following conditions, the A angle is: 45 °≤A≤75 °, B angle are: 45 °≤B≤75 °, C angle=180 °-A angle-B angle.

The utility model special case is that angle all is 60 ° between three of the body finger contact planes, and each plane connects by arc surface, and the body through hole is a circular port, and hole Nell wall axially has groove.

Adopt the utility model to write device, following advantage is arranged: 1. be triangular prism shaped owing to originally write the device outer shape, make the user naturally and understandably write the correct writing posture of maintenance with three faces that thumb, forefinger and three finger tips of middle finger are adjacent to triangular prism respectively.So can make the children that begin to practise writing form the correct body position that three fingers are write very soon.2. for certain correcting also being arranged from little students in middle and primary schools even the adult who does not form correct writing posture.3. increased the contact area of finger owing to write device, so write good hand touch, the long-time pen that uses, finger indefatigability with pen.4. break away from and originally write device, be accustomed to nature, do not have unconformable sensation with the three finger writing postures use hard-tipped pen of forming.

The utility model is described in further detail below in conjunction with drawings and Examples:

Fig. 1 is a kind of embodiment of the utility model front view of (the cover body profile is the regular triangular prism shape, and through hole is a circular port);

Fig. 2 is the K-K cutaway view of Fig. 1;

Fig. 3 is another embodiment of the utility model sectional view of (the cover body profile is the regular triangular prism shape, and through hole is tri-angle-holed);

Fig. 4 is unequal body sectional view for the utility model corner angle;

Fig. 5 is inserted in the state diagram of six rib pencils for the utility model.

With reference to Fig. 1, Fig. 2, the described device of writing of present embodiment, the cover body profile is regular triangular prism shaped, the body shape of through holes is circular port (shown in Figure 2), the top of the horn of each corner angle of triangular prism is made arc surface, the matter material can have certain flexible material with plastics, rubber etc., makes to write device certain elasticity is arranged, and is fixed in movably and writes the position.Write about the long 30mm of device, its through-hole diameter is more smaller than pencil diameter.The device of writing that is the regular triangular prism shape for profile, axially respectively have three place's grooves at triangular prism corner angle inwall, to each corner angle of body is the unequal device of writing, open a place or many places groove at the inwall of through hole as required, like this, when writing after device is inserted in pen, by strutting groove, pen is inserted in easily writes through hole and better matching, increase the friction of writing device and penholder, difficult slip with writing device.The shape of through hole also can be made into triangle, as shown in Figure 3 write device, also can be made into polygon, use to cooperate difform penholder.The cover body profile of writing device also can be made into the unequal triangular column of each corner angle, and the scope that each angle is chosen is that the A angle is: 45 °≤A≤75 °, B angle are: 45 °≤B≤75 °, C angle=180 °-A angle-B angle.Better suited angle is, A angle=45 °, B angle=45 °, C angle=90 °, as shown in Figure 4.

When using the utility model, to write device and be inserted in penholder from position, the nib 2.5cm left and right sides, thumb is by writing device one side, forefinger is by writing the device opposite side, middle finger withstands writes below the device, nameless and little finger of toe closes up naturally in the middle finger back, the three finger writing postures that the penholder upper shelf forms on tiger.The device of writing that profile is regular triangular prism shape body uses easily, need not differentiate and write direction, and the pickpocket refers to be attached to arbitrarily the direction of appointing of writing device.When using body to write device as the unequal triangular column of corner angle, paste the BC face with thumb, forefinger pastes the AC face, and middle finger pastes the AB face.

The utility model draws materials conveniently, makes simple, during use finger flexibly, comfortable feel to cultivating correct writing posture, alleviates that finger fatigue has very big benefit when writing.
