Abstract

The utility model discloses a device enabling a child to hold a pen correctly. The device is composed of a combined sleeve and an angle measurement rod, wherein the combined sleeve is composed of an index finger sleeve, a pen sleeve, a thumb sleeve and a middle finger sleeve and is made of non-poisonous plastic. The bent degree of the index finger sleeve, the thumb sleeve and the middle finger sleeve is consistent with the bent degree of knuckles when a child correctly holds a pen and writes to ensure that the index finger, the thumb and the middle finger are correctly positioned; the angle measurement rod can swing with a pin shaft as the center so as to be opened or folded and further ensure that the included angle between a penholder and a tabletop can be freely adjusted between 50 degrees and 60 degrees, after the included angle is checked out, a knurled nut is screwed for fixing. The device enabling a child to hold a pen correctly positions the pen holding positions of the thumb correctly, the middle finger and the index finger, well limits the naturally-bent shapes of the three fingers, facilitates coordination of the thumb, the index finger and the middle finger and the wrist, improves writing speed and quality, and avoids the phenomenon that a child does not correctly holds a pen, and therefore the eyesight of the child is affected; a student can open the angle measurement rod at any time to check whether the included angle between the penholder and the tabletop is correct or not and correct the angle if the angle is not right.

Description

A kind of children's correct holding device

Technical field

The utility model relates to a kind of instrument of correct holding can make children writing the time, belongs to children's stationery.

Background technology

Director professor Chu Renyuan of myopia key lab of the Ministry of Public Health means, an investigation has been carried out to the myopia teenager in this laboratory a few days ago, found that, the bathomorphic maximum origin cause of formation and do not lie in the eyes thought of tradition from books too close to, but wrong pen holding posture.The product (as fondling's appliance for holding pen) that several patents and market are all, substantially determined the position of thumb, forefinger and middle finger and three fingers and nib, because bone and the muscle development of child's hand are incomplete, adding each finger gripping vigour of style in literary composition degree is difficult to grasp, still have a lot of students or thumb stiff, or curved in forefinger, easily cause on the one hand fatigue, affect on the other hand the quality of writing, also affect child and point skeleton development; Pen and the angle of desktop also difficult grasp in addition.

The utility model content

The utility model has overcome the shortcoming of above-mentioned various appliance for holding pen, and the better children's correct holding of a kind of function device is provided.

Address these problems the technical scheme of employing:

A kind of children's correct holding device described in the utility model is by forefinger cover 1, the pen cap 2, thumbstall 3, the combination cover that middle fingerstall 4 forms, angular surveying bar 5, bearing pin 6, knurled nut 7 and half-round head square neck bolt 8 form, and this combination is applied mechanically non-toxic plastic and is made, forefinger cover 1, the pen cap 2, thumbstall 3, middle fingerstall 4 is fixed as one; The articulations digitorum manus curvature of the curvature at the articulations digitorum manus place of forefinger cover 1, thumbstall 3 and middle fingerstall 4 correct pen holding posture during with shown in Figure 3 writing is consistent, guarantees that forefinger, thumb and middle finger stretch into forefinger cover 1, thumbstall 2 and middle fingerstall 4, accurate positioning; Angular surveying bar 5 can swing centered by bearing pin 6, in order to open or fold, also can pull down, maximum 70 ° of its pendulum angle, adjust arbitrarily between 50-60 ° to guarantee penholder and desktop angle, in order to guarantee the pivot angle location, a deep-slotted chip breaker is established in the bottom of combination cover bottom penholder and middle finger angle bearing pin 6, as shown in Figure 4, and 70 ° of the effective angles of deep-slotted chip breaker, during angular surveying bar 5 swings suitable position, can tighten knurled nut 7 to fix.

The beneficial effects of the utility model are: accurately located the pen griping position of thumb, middle finger and forefinger, defined preferably the natural torsion shape of three fingers, be of value to the cooperation of thumb, forefinger, middle finger and wrist, improved write speed and quality; The student is the open angle measuring stick at any time, whether correctly detects penholder and tabletop angles, and is corrected.

The accompanying drawing explanation:

Fig. 1 is complete machine structure figure of the present utility model, by forefinger cover 1, and the pen cap 2, thumbstall 3, middle fingerstall 4 and angular surveying bar 5, bearing pin 6, knurled nut 7 and half-round head square neck bolt 8 form.

Fig. 2-1st, angle adjustment lever and the installation of combination cover, the front partial enlarged drawing of adjustment, Fig. 2-2nd, the centre section view of Fig. 2-1, unclamp knurled nut 7, and angle adjustment lever 5 can be rotated 0-70 ° centered by bearing pin 6,

Fig. 3 is that this appliance for holding pen is used schematic diagram, and this figure has showed tram and the posture held a pen.

The specific embodiment

A kind of children's correct holding device described in the utility model as shown in Figure 1, its forefinger cover 1, the pen cap 2, thumbstall 3, the combination cover that middle fingerstall 4 forms is made the appliance for holding pen of some different models, size and supporting angular surveying bar 5 with it according to length, the thickness of different children's finger.

The model of appliance for holding pen, size Selection are carried out under by teacher, being instructed.

The adjustment of the angle of center line and the desktop of pen should be carried out under fat or thin and personal preference's guidance according to the student by teacher as shown in Fig. 2-1 and Fig. 2-2.

Operational example

The pupil of one one grade, this gives birth to a appliance for holding pen the most small size on probation, his forefinger, thumb and middle finger is inserted in respectively to forefinger cover 1, thumbstall 3 and the middle fingerstall 4 of appliance for holding pen, if degree of tightness is suitable, selects correct; Pencil is inserted in this appliance for holding pen pen cap 2, make tip of a pencil apart from 3 centimetres of the front ends of forefinger cover 2; Unclamp knurled nut 7, angular surveying bar 5 tentatively is fixed on to the deep-slotted chip breaker middle part (at this moment pencil and desktop angle are about 58-60 °) as shown in Fig. 2-1, the lower end in contact paper of angle measuring stick 5 while allowing the pupil write, notice that student's wrist is not crooked as feel pencil and desktop angle more greatly, unclamp knurled nut 7, the angular surveying bar is swung to the right, pencil and desktop angle are diminished, pencil and desktop angle tighten the knurled nut after suitable until think; After the student grasps posture substantially, can unclamp knurled nut 7, the angular surveying bar is swung to left end and tightens knurled nut 7.

Tertion's pen holding posture is incorrect, selects the appliance for holding pen of large size, as stated above operation.
