Scale value is equipped with, square indentations and triangular groove, and length of side of square indentations etc. are provided with inside rectangular recess
In the half of rectangular recess length, triangular groove is right angle trigonometry connected in star, and two right-angle sides of triangular groove
Length is equal to the length of side of square indentations.
Provided with two square indentations inside rectangular recess, one of square indentations are by two triangular grooves
Constitute.
Buckle is equipped with rectangular recess, square indentations and triangular groove side.
Upper exterior surface is provided with the calculator renovated,
Upper exterior surface is provided with electronic watch.
On be covered with phonographic recorder.
Lower interior surface is provided with elastic ferrule.
Lower interior surface one end, which is provided with, passes through the battery-powered LED of in-built electrical.
The beneficial effects of the invention are as follows:
A kind of writing case for learning function with plane geometry of the present invention, by being set in simple stationery box cover
These simple plane geometry grooves of rectangle, square and triangle, can intuitively find out these plane geometry the length of side,
Relation between the features such as angle, can not only solve plane geometry learning aid problem in short supply, moreover it is possible to increase new use for writing case
On the way, can also be table while study in addition, can neatly store corresponding plane geometry in the groove set in writing case
Space is saved in face, also ensure that stationery is regular in writing case in addition, facility is provided for student, has also been correspondingly improved study effect
Rate, the present invention sets buckle on each plane geometry groove side, prevents from being placed on the plane geometry in groove and drops, simultaneously
The regularity in writing case can be ensured, design is simple, easy to use.
The calculator renovated is provided with the upper exterior surface of the present invention, calculator is directly combined in writing case
On, new function is provided for writing case, together folding and unfolding and carrying, it is more convenient when allowing calculator cooperating, study to use,
Further increase learning efficiency.
Phonographic recorder and electronic watch are set in the upper exterior surface of the present invention, student can be facilitated to see the time, while the record set
Sound device can be replicated fast and easily to content of the teacher on classroom, be conducive to reviewing and looked back, set in writing case lower cover
Elastic ferrule is put, can be fixed on various stationery are regular in writing case, is prevented during writing case is carried because of lid pine
The dynamic stationery caused in writing case is trickled down, and is brought inconvenience to student;It is provided with and is powered by internal battery in lower interior surface one end
LED, when there is accidental power failure during studying at night, LED that can be directly in openning pencil box is used for emergency lighting, simply
It is convenient.
