an abscissa axis 6 and an ordinate axis 5 are respectively arranged in the horizontal direction and the vertical direction by taking the right-hand palm root fulcrum B8 as an origin of coordinates;
a left writing interval line A9 is arranged by clockwise rotating a negative half shaft of an abscissa axis 6 by taking a right-hand palm root fulcrum B8 as a rotating point, a right writing interval line B10 is arranged by counterclockwise rotating a positive half shaft of an ordinate axis 5 by taking a right-hand palm root fulcrum B8 as a rotating point, and an area between the left writing interval line A9 and the right writing interval line B10 is a writing interval;
a wrist hooking correction barrier strip 3 is arranged along the left writing interval line A9, a base plate 2 is connected between the wrist hooking correction barrier strip 3 and the desktop body, screw through holes 4 are formed among the base plate 2, the wrist hooking correction barrier strip 3 and the panel body 1, and screw fixation is carried out through the screw through holes 4; one side of the crocheting wrist correction barrier strip 3 is superposed with the left writing interval line 9, and the writing interval is not occupied.
Use right hand palm root fulcrum B8 to be equipped with the right hand fulcrum circle 12 that the radius is 40 millimeters as the centre of a circle, right hand fulcrum circle 12 is located the negative semi-axis of abscissa axis 6 and is pointed finger position arc 11 for a short time with the positive semi-axis of ordinate axis 5 between the arc, with point of intersect that points of little finger position arc 11 and abscissa axis 6, ordinate axis 5 is tangent point, and two tangents do respectively right, upwards are little finger position arc reference line 13.
In addition, left side writing interval line A9 and right writing interval line B10 both ends extend to the limit portion of desktop body, with right hand palm root fulcrum B8 is the rotation point, is equipped with a left side writing interval line A9 with the negative semi-axis clockwise rotation 20-30 degrees of abscissa axis 6, uses right hand palm root fulcrum B8 as the rotation point, is equipped with a right side writing interval line B10 with the positive semi-axis anticlockwise rotation 30 degrees of ordinate axis 5, collude and all opened two screw through-holes 4 on wrist correction blend stop 3, backing plate 2 and the panel body 1, fix through two screws. The length of backing plate 2 is less than the length of colluding wrist and correcting blend stop 3, collude the end contactless right hand fulcrum circle 12 of wrist and correcting blend stop 3, left hand palm root fulcrum A7 has a left hand palm root fulcrum position reference line 14 downwards with the parallel extension of axis of ordinates 5.
The utility model discloses when carrying out concrete use again, left and right hand palm root fulcrum corresponds left hand palm root fulcrum A7 and right hand palm root fulcrum B8's position respectively, and left and right hand is put on these two fulcrum positions, can guarantee that both hands are put in the middle of the desktop and lean on the position of right slightly, and the nib is seen to the eyes of being convenient for, holds the chinese character structure, is favorable to writing. Meanwhile, the chair can be rightly seated, and cannot be inclined leftwards or rightwards. Therefore, when the user writes with the right hand, the user controls the exercise book with the left hand, the attention of children is improved, and the learning efficiency is improved.
Abscissa axis 6 (left and right hand palm root fulcrum point reference line), ordinate axis 5 (right hand palm root fulcrum point reference line): when writing, the homework book presses the position point of the palm root fulcrum B8 of the right hand, and the palm root fulcrum B8 of the right hand can be conveniently found according to the two coordinate axes.
Left-hand palm root fulcrum position reference line 14: the exercise book presses the left-hand palm root fulcrum A7, and the left-hand palm root fulcrum A7 can be found by referring to the left-hand palm root fulcrum position reference line 14 and the abscissa axis 6.
A circle with the radius of 40 mm is drawn as an interval for fixing the right hand by taking the root fulcrum B8 of the palm of the right hand as the center of the circle and taking the circle as the fulcrum circle 12 of the right hand, the size of the circle is approximately equal to that of the right hand, and the part of the right hand contacting the desktop can not exceed the circle.
The backing plate 2 enables the wrist hooking correction barrier strip 3 to have a space with the desktop, so that the operation notebook can move left and right according to the writing requirement.
When the wrist hooking correction barrier 3 is used for writing, the homework book presses part of the left writing interval line A9, and the writing interval is not easy to grasp. Especially, after the students with serious wrist hooking are provided with the wrist hooking correction barrier 3, the writing interval is obviously told, the pen point is forced to point to the left front for writing, and the wrist hooking habit is effectively changed.
Left writing interval line a9, right writing interval line B10: the writing interval is positioned by these two lines. When writing, the pen tip is not directed to the left, but to the front left. Because the Chinese characters are square characters, a large number of horizontal strokes and longitudinal strokes are provided, the pen point points to the left front, the wrist can be used as the main part, the finger can be used as the auxiliary part, and the writing speed is improved.
The screw through hole 4 is fixed backing plate 2 and collude wrist correction blend stop 3 on panel body 1 with the screw, lets collude one side and the left writing interval line 9 coincidence of wrist correction blend stop 3, does not occupy again and writes the interval.
Little finger position arc 11: the little finger is close to the arc line, so that the little finger is not close to the palm, the 'finger full and palm deficiency' is ensured, and a larger telescopic interval is provided during writing and finger transportation.
Little finger position arc reference line 13: when writing, the exercise book presses the little finger position arc line 11, and the approximate position where the little finger is placed can be found according to the two tangent lines.
The left palm root fulcrum a7 and the right palm root fulcrum B8 in the utility model can also be called as left palm root fulcrum point and right palm root fulcrum point.
