Abstract
The invention discloses a multifunctional plotting instrument, which relates to the technical field of a teaching aid and has functions of a straightedge, a triangle, a protractor and a bow compass at the same time. The board body of the multifunctional plotting instrument is a semicircle; two slots are led out from the central dot of the board body and arranged respectively on the angle of 0 degree and the angle of 45 degrees along the 180-degree direction; a circular through-hole is arranged from the central dot at an interval of 5 mm; a semicircular slot is arranged on the surface of the board body; a sucking disk is embedded in the centre of the semicircle; the sucking disk and the board body are in running fit. The plotting instrument has the advantages of simple structure, material-saving and convenient carrying, thereby being applied to the technical field of the teaching aid broadly.
Description
Affiliated technical field
The invention belongs to the teaching aid technical field, is a kind of teaching multi-function drawing instrument specifically.
Background technology
At present, the ruler that Faculty and Students use in teaching process, set square, protractor and compasses mostly are the drawing instrument of simple function, and in use existing such as one is to carry inconvenience, and the 2nd, problems such as buying expenses increase.
Summary of the invention
Carry shortcomings such as inconvenient and buying expenses increase for what the drawing instrument that overcomes existing simple function existed, the invention provides a kind of multifunctional drawing instrument, its not only simple and easy practicality is convenient for carrying, and economical and practical.
The technical solution adopted for the present invention to solve the technical problems is: the multi-function drawing instrument plate body is for semicircle, draw two grooves from the plate body centre dot, in 0 ° of angle and 45 position,, be distributed with a manhole every 5mm respectively from round dot along 180 ° of directions.Have a semi-circular groove on the plate body surface.Embed a sucker at semicircle circle centre position, sucker and plate body are rotatably assorted.
Good effect of the present invention is: owing to design feature of the present invention, made full use of the space on plotter surface, made this plotter have the function of ruler, set square and protractor.Embed a sucker at semicircle plate body circle centre position, sucker and plate body are rotatably assorted, and can make compasses and use.The present invention saves the space, and economical with materials is convenient for carrying, and has also saved user's expense.
Description of drawings
Accompanying drawing is the structural representation of multi-function drawing instrument.
In the accompanying drawings, 1, plate body, 2, semi-circular groove, 3, the 45 groove, 4,0 ° of chamfered grooves, 5, manhole, 6, sucker.
