Abstract

The utility model belongs to pen technology field, refering in particular to one meets children and points physiological Nearsightedness-preventing pen, comprise penholder and pen core, it is characterized in that barrel grip increases thickness with respect to the one side of middle finger, raise written position, compared with existing pen, while writing, nib has pushed away front on paper about 1cm, when thumb forefinger finger tip and nib distance little during to 1.5cm, also can be clear that nib, avoiding reason because holding a pen to cannot see nib is forced to bow, torticollis writes and causes myopia, adapt to children's hand-type little, the weak physilogical characteristics of finger power are for the particular/special requirement of pen.The position that holds a pen of grip part thumb and forefinger is the paraboloidal pen-holding groove of ellipse of indent, coincide with the external drum parabola of finger tip, thumb and forefinger is held a pen and more surely really do one's bit inside.Top in the middle of thumb and forefinger pen-holding groove is to stop that thumb and forefinger intersect the obstruct tooth holding a pen, and have corrected bad writing posture.Grip part is plane with respect to the one side of middle finger, has increased the contact-making surface of the front dactylus of middle finger and penholder, has alleviated the pressure of penholder to middle finger articulations digitorum manus, has improved the comfort level of writing, and finger is played a protective role.

Description

One meets children and points physiological Nearsightedness-preventing pen

Technical field

The utility model belongs to pen technology field, refers in particular to one and meets children and point physiological Nearsightedness-preventing pen.

Background technology

Show according to " national physique examining report for the second time ", national adolescent student poor eyesight rate is high, continues to rise, and pupil 31.67%, and junior school student 58.07%, and high school student 76.02%.And according to authoritative institution's investigation, causing near-sighted main cause is wrong pen holding posture.Face the more posture of taking thumb and forefinger not to collide of student, myopia has in student the student of 95% left and right to exist thumb to collide with forefinger to hold a pen, intersect and hold a pen or hold a pen phenomenon on the low side, cause thus thumb to block sight line, cause and do not see nib, be forced to bow or head askew left, thereby the distance of further eyes and books, increases the near-sighted incidence of disease.The reason on the low side that holds a pen be students in middle and primary schools' health in the stage of development, bone is tender, hand-type is little, a little less than referring to power, remain on 3cm left and right by student writing code requirement thumb forefinger finger tip and nib distance and write, finger does not make power, writes not freely, write bad word, and it is lower to hold a pen, and easily exerts all one's strength.

Summary of the invention

The purpose of this utility model be solve adolescent student while writing thumb collide with forefinger hold a pen, intersect hold a pen and hold a pen on the low side cause to point block sight line, cause and do not see nib and be forced to bow or torticollis writes and causes the problem of hypometropia, stravismus, make pen adapt to children's hand-type physilogical characteristics, and improve the comfort level of writing.

The purpose of this utility model is achieved in that

One meets children and points physiological Nearsightedness-preventing pen, comprise penholder and pen core, it is characterized in that barrel grip increases thickness with respect to the one side of middle finger, the position that holds a pen of grip part thumb and forefinger is the pen-holding groove of indent, top in the middle of thumb and forefinger pen-holding groove is to stop that thumb and forefinger intersect the obstruct tooth holding a pen, the front end of penholder is written locking cap, and the tail end of penholder is tail plug.

Meet children in above-mentioned one and point in physiological Nearsightedness-preventing pen, the surface of described thumb and forefinger pen-holding groove is the oval parabola of indent.

Meet children in above-mentioned one and point in physiological Nearsightedness-preventing pen, described grip part is plane with respect to the one side of middle finger.

Meet children in above-mentioned one and point in physiological Nearsightedness-preventing pen, on described written locking cap, have the cap for brush matching with it.

The utility model compared to existing technology outstanding and useful technique effect is:

1, the utility model increases thickness by barrel grip with respect to the one side of middle finger, raise written position, compared with existing pen, while writing, nib has pushed away on paper 1cm left and right front, when thumb forefinger finger tip and nib during to 1.5cm, also can be clear that nib apart from little, avoid reason because holding a pen to cannot see that nib is forced to bow, torticollis writes causes myopia, adapt to children's hand-type little, refer to the particular/special requirement of the weak physilogical characteristics of power for pen;

2, the top in the middle of the utility model middle finger and forefinger pen-holding groove has and stops that thumb and forefinger intersect the obstruct tooth holding a pen, and have corrected bad writing posture;

3, the paraboloidal pen-holding groove of the ellipse of indent in the utility model, coincide with the external drum parabola of finger tip, thumb and forefinger is held a pen and more surely really do one's bit inside.

Brief description of the drawings

Fig. 1 is the utility model schematic side view;

Fig. 2 is the utility model schematic top plan view.

The utility model is further described with specific embodiment below in conjunction with accompanying drawing, referring to Fig. 1-2:

One meets children and points physiological Nearsightedness-preventing pen, comprise penholder and pen core, it is characterized in that barrel grip increases thickness with respect to the one side 1 of middle finger, the position that holds a pen of grip part thumb and forefinger is the pen-holding groove 2 of indent, top in the middle of thumb and forefinger pen-holding groove is to stop that thumb and forefinger intersect the obstruct tooth 3 holding a pen, the front end of penholder is written locking cap 5, and the tail end of penholder is tail plug 4.

Meet children in above-mentioned one and point in physiological Nearsightedness-preventing pen, the surface of described thumb and forefinger pen-holding groove 2 is oval parabolas of indent.。

Meet children in above-mentioned one and point in physiological Nearsightedness-preventing pen, described grip part is plane with respect to the one side 1 of middle finger.

Meet children in above-mentioned one and point in physiological Nearsightedness-preventing pen, on described written locking cap, have the cap for brush 7 matching with it.

When use, pen core is inserted in penholder, written locking cap 5 is enclosed within nib 6 and is tightened with penholder, corresponding thumb and the forefinger pen-holding groove of gripping of thumb and forefinger, middle finger props up corresponding middle finger position, pen-holding groove below, just can write freely.

Above-described embodiment is only preferred embodiment of the present utility model, not limits according to this protection domain of the present utility model, therefore: all equivalences of doing according to structure of the present utility model, shape, principle change, within all should being covered by protection domain of the present utility model.
