Description

Multifunctional compass

Affiliated technical field

The utility model relates to teaching appliance, especially belongs to write or a kind of multifunctional compass of the usefulness of drawing.

Background technology

People often need to be used multiple drawing instruments such as compasses, protractor, pencil, drawing pen, rubber in order to draw various drawings, chart and figure in the middle of activities such as study, teaching, scientific research; At present; widely used common compasses; drawing instrument commonly used such as ruler and protractor is function singleness all; therefore; for finishing a drawing, the illustrator need prepare all drawing instruments commonly used, these drawing instruments of a great variety; too disperse; made a lot of effort in order to address this problem people, as, adopt the Napier's compasses that common compasses and protractor are combined into one to finish taking measurement of an angle and draw circle in the drawing course; the technical problems such as line of making an arc; the part but this technology still has some deficits also exists function incomplete, and purposes is not extensive; therefore, user's study and work efficient regular meeting is affected.

Summary of the invention

The purpose of this utility model is to provide a kind of multifunctional compass, to the simple function of more drawing instrument be made up effectively as far as possible, design a kind of multifunctional compass, this multifunctional compass can roll into one the function of multiple drawing instrument, one tool is used more, thereby it is of a great variety to solve drawing instrument commonly used well, too disperses, and uses and carry problem such as equal inconvenience.

This technical scheme of using novel its technical problem of solution to be adopted is: a kind of multifunctional compass, it comprises link, angle, the line pin, protractor, the pen cap, drawing pen, pencil, Rubber eraser clamp, rubber, pencil sharpener, electronic watch, magnifying glass, stem and holding screw, it is characterized in that: the upper end of angle and line pin and the same point of link lower end are hinged, and can free deciliter, the one side of link is provided with electronic watch, so that the user grasps the working and learning time at any time, the another side of link is provided with Rubber eraser clamp and pencil sharpener, Rubber eraser clamp becomes the fluted body shape, accompany rubber in the concave groove of Rubber eraser clamp, change the mistake that occurs in the drawing course so that in time wipe, the use of pencil sharpener is identical with common pencil sharpener; Described angle rectangularity shape, indicate length dimension in the inner part on one side in the front, can be used as ruler when needing to draw straight line uses, be provided with protractor on one side in the angle outside, be used to during drawing take measurement of an angle, the protractor and the angle outside are adopted and are flexibly connected, can fold, during use, the front of protractor becomes outward extending semi-circular shape at grade with the one side that angle is marked with long measure, thereby forms the working face of protractor and ruler one, not time spent, protractor can inwardly fold by active section, and the structure of multifunctional compass is tightened more; The rule pin is equipped with in the angle lower end, and magnifying glass is located at angle bottom and protractor lower end and the centre position above the rule pin, and its function is that drawing is the tiny link that is used to check, confirm and repair institute's drawing shape, thereby guarantees the accuracy and the drawing quality of figure; Described line pin is connected with holding screw with the cylindrical pen cap, and cylindrical pen cap two is furnished with drawing pen and pencil respectively, so that the needs when drawing are selected for use, during use, can reconcile the angle of drawing pen and pencil by holding screw.

Useful fruit of the present utility model is: because the technical scheme that adopted multiple drawing instrument to be integrated, the many usefulness of a tool are easy to carry, and are of many uses, practical and convenient, save time, and help to improve practical person's working and learning efficient.

Description of drawings

Below in conjunction with accompanying drawing and example the utility model is further specified.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is a schematic side view of the present utility model.

Among the figure: 1 stem, 2. pencil sharpener 3. links, 4. line pin .5 drawing pen, 6 pens cap, 7 pencils, 8 rule pins, 9. magnifying glass, 10. angle, 11 protractors, 12. rubbers, 13. electronic watches, 14. Rubber eraser clamps, 15. holding screws.

The specific embodiment

In Fig. 1 and Fig. 2, a kind of multifunctional compass, it comprises link (3), angle (10), line pin (4), protractor (11), the pen cap (6), drawing pen (5), pencil (7), Rubber eraser clamp (14), rubber (12), pencil sharpener (2), electronic watch (13), magnifying glass (9), stem (1) and holding screw (15), its concrete structure is: the upper end of angle (10) and line pin (4) and the same point of link (3) lower end are hinged, and can free deciliter, the one side of link (3) is provided with electronic watch (13), so that the user grasps the working and learning time at any time, the another side of link (3) is provided with Rubber eraser clamp (14) and pencil sharpener (2), Rubber eraser clamp (14) becomes the fluted body shape, accompany rubber (12) in the concave shape groove of Rubber eraser clamp (14), change the mistake that occurs in the drawing course so that in time wipe, the use of pencil sharpener (2) is identical with common pencil sharpener; Described angle (10) rectangularity shape, indicate length dimension in the inner part on one side in the front, can be used as ruler when needing to draw straight line uses, be provided with protractor (11) on one side in angle (10) outside, be used to during drawing take measurement of an angle, protractor (11) adopts with angle (10) outside and flexibly connects, can fold, the one side that the front of protractor during use (11) and angle (10) indicate long measure at grade, become outward extending semi-circular shape, the working face of shaping protractor (11) and ruler one, not time spent, protractor (11) can inwardly fold by active section, and the structure of multifunctional compass is tightened more; Rule pin (8) is equipped with in angle (10) lower end; Magnifying glass (9) is located at angle (10) bottom and protractor (11) lower end and the centre position above the rule pins (8), its function is that drawing is the tiny link that is used to check, confirm and repair institute's drawing shape, thereby guarantee the accuracy and the drawing quality of figure, described line pin (4) is connected with holding screw (15) with the cylindrical pen cap (6), the cylindrical pen cap (6) two is furnished with drawing pen (5) and pencil (7) respectively, so that the needs during according to drawing are selected for use, during use, can reconcile the angle of drawing pen (5) and pencil (7) by holding screw (15).
