The utility model discloses multifunctional teaching compasses belonging to stationery, and relates to compasses with functions of a ruler, a triangle, a protractor and compasses. The multifunctional teaching compasses comprise a supporting rod, and the supporting rod comprises a fixing leg and a pencil lead leg. The multifunctional teaching compasses are characterized in that one end of the fixing leg is provided with a centering pin slot; one end of the pencil lead leg is provided with a pencil slot; the other ends of the fixing leg and the pencil lead leg are shaped like right-angle sectors with the same size; the fixing leg and the pencil lead leg are connected by a rotary shaft at the vertex of the right-angle sector; the supporting rod is provided with scales to form a ruler structure; and the positions of the right-angle sectors of the fixing leg and the pencil lead leg are also provided with scales to form a protractor structure. Compared with the prior art, the multifunctional teaching compasses have the characteristics of simple structure, convenient use and carrying, wide application and the like.
Description
Technical field
The utility model relates to a kind of stationery, specifically a kind of multifunctional teaching compasses.
Background technology
At present, people draw various figures need use multiple instruments such as ruler, set square, protractor and compasses, a lot of figures all need two or two above instruments to match and can draw smoothly, and existing various drawing instruments are function singleness, the independent use, this just brings all inconvenience to the illustrator.
The utility model content
The purpose of this utility model is to provide a kind of multifunctional teaching compasses, and these compasses integrate the function of multiple drawing instrument, and use is carried all very convenient.
The technical scheme in the invention for solving the technical problem is: this kind multifunctional teaching compasses, comprise support bar, support bar comprises fixing feet and lead for retractable pencil pin, it is characterized in that, fixing feet one end is provided with the centering pin slot, lead for retractable pencil pin one end is provided with the penholder groove, and the other end of fixing feet and lead for retractable pencil pin is that the equal right angle of size shape is fan-shaped, and fixing feet is connected with rotating shaft with the lead for retractable pencil pin place, summit fan-shaped at the right angle; Being provided with scale on support bar is the ruler structure, and being provided with scale at the fan-shaped place, right angle of fixing feet and lead for retractable pencil pin is angle gage structure.
The beneficial effects of the utility model are: support bar can be used as ruler and uses, and realizes setting-out and tolerance; Protractor scale on the right angle is fan-shaped can realize measuring angle, and can assist the draw angle of required angle of people; Capable of being combinedly under the reference of protractor between fixing feet and the lead for retractable pencil pin go out set square.Gather multi-function in integral whole, use easy to carry, of many uses.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of Fig. 1 user mode.
Among the figure: 1 fixing feet, 2 centering pins, 3 lead for retractable pencil pin, 4 chalks, 5 rotating shafts, 6 protractors.
The specific embodiment
As shown in Figure 1 and Figure 2.Multifunctional teaching compasses, comprise support bar, support bar comprises fixing feet 1 and lead for retractable pencil pin 3, fixing feet 1 one ends are provided with the centering pin slot, lead for retractable pencil pin 3 one ends are provided with the penholder groove, the other end of fixing feet 1 and lead for retractable pencil pin 3 is that the equal right angle of size shape is fan-shaped, and fixing feet 1 is connected with rotating shaft 5 with lead for retractable pencil pin 3 place, summit fan-shaped at the right angle; Being provided with scale on support bar is the ruler structure, and being provided with scale at the fan-shaped place, right angle of fixing feet 1 and lead for retractable pencil pin 3 is angle gage structure.
Fixing feet 1 and lead for retractable pencil pin 3 should allow both the fan-shaped part symmetry in right angle when being connected, constitute a complete protractor 6 during two right angle fan outs.During use, centering pin 2 is fixed in the centering pin slot of fixing feet 1, chalk 4 is fixed in the penholder groove of lead for retractable pencil pin 3, centering pin 2 is fixed on circle centre position, lead for retractable pencil pin 35 rotate to be determined radius of a circle, the available chalk 4 required circle that draws around the shaft.
Support bar is provided with scale, can be used as ruler and uses, and makes straight line and tolerance length, described scale can be located on the fixing feet 1, also can be located on the lead for retractable pencil pin 3, and perhaps both are equipped with scale, be simplified structure, be convenient to explanation, set scale in the present embodiment and be arranged on the fixing feet 1.
Lead for retractable pencil pin 35 rotates around the shaft, the fan-shaped lap in two right angles can be corresponding on fan-shaped at the right angle corresponding scale, people are reference with this scale, can draw the angle between fixing feet 1 and the lead for retractable pencil pin 3, can make the angle of required angle fast, the form that goes out set square also capable of being combined is used as set square.During two right angle fan outs, protractor 6 can be used for measuring angle.
In other embodiments, the utility model can be dwindled, chalk is changed to pencil use for the student, centering pin 2 not the time spent removablely prevent to hurt the people down, security is better.
