Abstract

The utility model relates to a hand harmless penholder. The penholder is characterized in that the cross section of the penholder (3) is in the shape of an isosceles triangle, the nib (2) is in the shape of an isosceles trigonous frustum. Due to the cross section of the penholder is in the shape of an isosceles triangle, the contact surface for the midfinger and the thumb for hold the pen is enlarged and the distance between the index finger and the midfinger is reduced. The distance between the index finger and the midfinger can be enlarged by adopting other triangles. Therefore, the penholder in the isosceles triangular shape has a bigger contact surface among the three fingers and the penholder, facilitating in smooth writing and short sight protection. No matter how long one is writing, the fingers don't feel tired and the worries about the distortion and deformation of the fingers can be ignored, because the penholder provided has a finger contact surface more than 5 times than that of the round penholder; meanwhile, when in use, the penholder is helpful in the correction of pen holding gesture.

Description

A kind of handwriting bar of not hindering

Technical field:

The utility model relates to a kind of pen, especially a kind of handwriting bar of not hindering.

Background technology:

The external form of writing penholder on the existing market is cylinder, six water chestnut posts etc., and the body of this pen is write the too major injury that can not constitute the adversary for the adult, but just different for the pupil.Their bone of adolescent student is undeveloped mature still, uses this Pen Association to produce the injury that the pupil is pointed for a long time, when you observe their pinkie, finds that pinkie twists, distortion.Owing to produce tired when finishing numerous operation, eyes are near the paper of writing, eyesight descends gradually, the teen-age myopia ratio of China rises gradually at present, its reason is exactly that the contact-making surface of circular penholder and finger is too small, when you hold with a firm grip after penholder writes a period of time, will feel that finger aches numbness ....

The utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of handwriting bar of not hindering is provided.

For achieving the above object, the technical scheme that the utility model adopted is: a kind of handwriting bar of not hindering, comprise pen core, nib, penholder, and it is characterized in that: the cross section of penholder is isosceles triangle, and nib is isosceles triangular taper type.

Described a kind of handwriting bar of not hindering is characterized in that: the waist of isosceles triangle penholder with the ratio of bottom side length is: 1.2～1.5: 0.7～1.

Described a kind of handwriting bar of not hindering is characterized in that: the long 12～15mm of the waist of isosceles triangle penholder, bottom side length is 7～10mm.

The utility model beneficial effect compared with prior art: because this penholder cross section is isosceles triangle, enlarged the contact-making surface that middle finger and thumb hold a pen, reduced the distance of forefinger and middle finger.And adopt other triangle to increase the distance of forefinger and middle finger easily.Therefore, the isosceles triangle penholder makes three fingers and the penholder that hold a pen that bigger contact-making surface be arranged, write happy, pre-myopia prevention.No matter how long you write, and finger does not think tired, does not more worry the torsional deformation of finger, because the penholder of this design is bigger more than 5 times than the finger contact-making surface of circular penholder; When using this simultaneously, can correct writing posture effectively again.

Description of drawings:

Fig. 1 is a front view of the present utility model;

Fig. 2 is the left view of Fig. 1.

Among the figure:

1. pen core, 2. nib, 3. handwriting bar, 4. base, 5. waist.

The specific embodiment:

Describe the utility model in detail below in conjunction with accompanying drawing:

Shown in Fig. 1-2, this does not hinder the handwriting bar, comprises pen core 1, nib 2, penholder 3, and the cross section of penholder 3 is isosceles triangle, and nib 2 is isosceles triangular taper type.

The waist 5 of described isosceles triangle penholder 3 with the ratio of base 4 length is: 1.2～1.5: 0.7～1.

The waist 5 long 12～15mm of described isosceles triangle penholder 3, base 4 length are 7～10mm.

This penholder is applicable to any penholder, all in the open scope of this patent.

The penholder 3 that the children of nursery class use can be selected less isosceles triangle penholder 3, as: waist 5 long 12mm, base 4 length are 7mm.The pupil of 1-3 grade can select the isosceles triangle penholder 3 of low middling, and as waist 5 long 13mm, base 4 length are 8mm.The pupil of 4-6 grade can select medium isosceles triangle penholder 3, and as waist 5 long 14mm, base 4 length are 9mm.The above middle school student in junior middle school can select bigger isosceles triangle penholder 3, and as waist 5 long 15mm, base 4 length are 10mm.

This pen can be selected the environment-friendly materials manufacturing for use, and the one, the waste paper regulation law; The 2nd, the string injection molding.Method for making: (1), waste paper regulation law.Waste paper has been cut out fixed dimension, first control core, a thin garden of control rod, both merging more then.Technological process is: sanction material-gluing-roll-die mould-curing-surface treatment-finished product.(2), string injection molding.Discarded straw pulverizes the back and glue mixes, and enters compression moulding in the shaper, the pen core of packing into, and the appearance dress pastes to be finished.Technological process is: raw material pulverizing-injection moulding-installation pen core-external coating-packed products.
