Abstract
A kind of combination ruler, be provided with screw in one end of ruler, drawing square installed by the screw above ruler, installation hornwork on the screw above drawing square, the screw above protractor is installed isoceles triangle chi, the end winding support nut of screw.The one end at 30 degree of angles of drawing square is equipped with screw, a corner of protractor is equipped with screw, the right angle of isoceles triangle chi is equipped with screw.Screw adopts flat head screw, and nut adopts two nut overlaps to be fastened and fixed.Ruler, the drawing square of the utility model by student is commonly used, isoceles triangle chi is together with protractor screw association, thus allow student in use reduce the trouble leaving behind certain equipment, also better can receive simultaneously, reduce the damage of these utensils.Utilize the structure of screw these chis can be found a binding site combined, can rotate around screw again simultaneously, four article be combined, and does not affect respective effect.
Description
Art
The utility model relates to a kind of study article, relates in particular to a kind of multiple chi screw to be combined, and a kind of rotation can be selected as required to come the combination ruler of use.
Background technology
Student often there will be and leaves behind some measurer chi because of careless in study at ordinary times, thus brings certain trouble to attending class.Several scrappy in addition measurer chis are put separately and are also easy to damage.
Utility model content
The purpose of this utility model overcomes the deficiencies in the prior art part, provides a kind of and multiple chi screw is combined, and a kind of rotation can be selected as required to come the combination ruler of use.
The utility model solves the technical scheme that its technical problem adopts: a kind of combination ruler, comprise ruler, one end of ruler is provided with screw, drawing square installed by screw above ruler, installation hornwork on screw above drawing square, screw above protractor is installed isoceles triangle chi, the end winding support nut of screw.The one end at 30 degree of angles of drawing square is equipped with screw, a corner of protractor is equipped with screw, the right angle of isoceles triangle chi is equipped with screw.Screw adopts flat head screw, and nut adopts two nut overlaps to be fastened and fixed.
The beneficial effects of the utility model are, by ruler, the drawing square student commonly used, isoceles triangle chi together with protractor screw association, thus allows student in use reduce the trouble leaving behind certain equipment, also better can receive simultaneously, reduce the damage of these utensils.By being combined by various chi, both reduce the trouble forgotten, simultaneously again can these study articles of reasonable protection.Utilize the structure of screw these chis can be found a binding site combined, can rotate around screw again simultaneously, four article be combined, and does not affect respective effect.
