Abstract
The utility model discloses a combined geometry tool, relates to study articles for students, and is especially suitable for middle school students. The combined geometry tool comprises a ruler, a set square, and a protractor, and is characterized in that one ends of the ruler, the set square and the protractor are respectively provided with a small round hole, so that the ruler, the set square and the protractor can be connected together by a rotatable shaft inserted into the small round hole. The beneficial effects of the combined geometry tool disclosed by the utility model lie in that the connection of the ruler, the set square and the protractor by the rotatable shaft can effectively solve the defect of influenced studying due to carrying of incomplete geometry tools, and the three geometry tools can be taken out of a writing case or school bag once, so that the learning efficiency can be improved.
Description
Technical field
The utility model belongs to a kind of student's study article, particularly is suitable for how much instruments that middle school student use.
Background technology
Middle school student usually need the use amount hornwork in how much classes of last mathematics, ruler, and how much instruments such as set square, middle school student because some are former thereby be with not umbra to ring and use, disorderly look in school bag sometimes sometimes, lose time, thus the efficient of interfering with one's studies.
The utility model content
In order to overcome that middle school student interfere with one's studies because of complete how much instruments of band and to look for the interfere with one's studies deficiency of efficient of how much instruments in the school bag civil strike; The purpose of the utility model provides a kind of combinatorial geometry instrument; This utility model can so that classmates find very rapidly class hour for how much and look for complete own geometry instruments at last mathematics, to improve learning efficiency.
The technical scheme that its technical problem of the utility model solution is taked is: a kind of combinatorial geometry instrument; Comprise ruler, set square, protractor; It is characterized in that: an end of described ruler, set square, protractor is respectively arranged with tiny circular hole, and described ruler, set square, protractor interconnect through the turning cylinder that is plugged in the tiny circular hole.
The beneficial effect of the utility model is because with ruler; Set square; Three kinds of how much instruments of protractor are connected together through turning cylinder; Thereby efficiently solve the deficiency that middle school student interfere with one's studies with complete how much instruments, thereby and can be disposable three kinds of how much instruments be taken out in school bag or the writing case and improved learning efficiency.
