Abstract
The utility model discloses a multifunctional compass, relating to a drawing tool; the multifunctional compass consists of support legs (1, 1'), an angle gauge (2) and a ruler (3), wherein the upper sides of fixed shafts (12) of the support legs (1, 1') are connected with the angle gauge (2); a retainer ring (21) is arranged outside the angle gauge (2); a rotary ring (5) is positioned on the top of the retainer ring (21); the lower sides of the fixed shafts (12) of the support legs (1, 1') are respectively provided with arc scales (4); and the ruler (3) is arranged outside the support leg (1) connected with the arc scales (4). The multifunctional compass has the functions of other drawing tools besides the function of traditional compass and can draw a variety of pictures, thus preventing the trouble caused by use of a variety of drawing tools when students draw the pictures, and reducing use cost. In addition, owing to easiness in production and convenience in use and carrying, the multifunctional compass can be used by students for drawing.
Description
Technical field
The utility model relates to a kind of drawing instrument, relates in particular to a kind of multifunctional compass.
Background technology
The instrument of compasses to be students be used for when learning mathematics, drawing draw circles or string.But the student not only needs outside draw circles or the string when drawing, and also need use and draw some other figures, like: triangle, quadrangle, trapezoidal etc.Traditional compasses, function singleness can not be accomplished the making of other figures beyond circle or the string, so; The student except needs use compasses, also needs drawing instruments such as ruler, set square, protractor when drawing; Make the student in drawing course, use this drawing instrument a little while, use the sort of drawing instrument for a moment; Vary, very trouble is carried also inconvenient.
Summary of the invention
The technical problem that the utility model will solve is: a kind of function of compasses, ruler, set square, protractor, multifunctional compass easy to use and carry of integrating is provided.
In order to solve above technical problem, the technical scheme that the utility model adopted is: this a kind of multifunctional compass is made up of supporting leg, protractor and ruler.It is characterized in that: above the fixed axis of supporting leg, connect a protractor, there is a guard ring outside of protractor, and the top of guard ring is provided with a swivel becket; The fixed axis below of supporting leg is provided with the arc engineer's scale, and an end of arc engineer's scale is connected the inboard of a supporting leg, and the other end passes from the hole on another supporting leg, and the position in hole is corresponding with the position that its supporting leg connects the arc engineer's scale.The cross section in hole and arc engineer's scale cross section adapt; The arc engineer's scale can slide in the hole, is provided with ruler at a leg outer side that connects the arc engineer's scale.
In addition, the below at protractor zero point is provided with a window of drawing angular vertex; Be provided with the space of drawing angle between protractor and the guard ring, the space is wide to be 0.3-0.6cm.
The beneficial effect of this utility model is: a kind of multifunctional compass is provided, and this multifunctional compass also has the function of other drawing instruments except having traditional compasses function; Can draw multiple figure; Use multiple drawing instrument trouble caused when having avoided the student to draw, reduced use cost, and make easily; Easy to use and carry, can supply the numerous students use of drawing.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model.
Specific embodiments
Make the utility model with reference to accompanying drawing 1; This a kind of multifunctional compass by supporting leg 1,1 ', protractor 2 and ruler 3 constitute; Supporting leg 1,1 ' fixed axis 12 above connect protractor 2, there is a guard ring 21 outside of protractor 2, the top of guard ring 21 is provided with a swivel becket 5; Supporting leg 1,1 ' fixed axis 12 belows be provided with arc engineer's scale 4; One end of arc engineer's scale 4 is connected the inboard of supporting leg 1; The other end from the supporting leg 1 ' hole 11 pass; The position in hole 11 is corresponding with the position that supporting leg 1 connects arc engineer's scale 4, and the cross section of the cross section in hole 11 and arc engineer's scale 4 adapts, and arc engineer's scale 4 can slide in hole 11; Supporting leg 1 outside that connects arc engineer's scale 4 is provided with ruler 3; The below at zero point of protractor 2 also is provided with the window 22 of drawing angular vertex; Establish the space 23 of the drafting angle of the wide 0.5cm of being between protractor 2 and the guard ring 21.
