Abstract

Multi-function protractor,Including transparent measurement plate,There is protractor in the measurement plate,The protractor is equipped with to be stitched for the setting-out of picture angle line,The center of the protractor is that setting-out assists position,Setting-out auxiliary position is equipped with the guiding slope for setting-out,The inclined-plane for being oriented to slope extends to the central point of protractor,So that central point of the one end of setting-out seam to protractor,Therefore first line only need to first be finished when drawing angle,And adjust protractor,Finish first line is set to be aligned with the angle line needed on protractor,The angle between first line and setting-out seam is exactly to need the angle of picture at this time,Then pen tip setting-out seam is inserted into directly to draw,And pen tip can be inserted into the central point of the protractor picture Article 2 line directly since the vertex of first line along slope is oriented to,Angle to draw is more accurate,It is convenient.

Description

Multi-function protractor

Technical field

The utility model is related to multi-function protractors.

Background technology

Protractor can draw angle, measuring angle, draw vertical line, and protractor is that large, medium and small student and engineers and technicians draw The indispensable tool of figure, is particularly useful for pupils and students, factory, workshop, carpenter, skilled worker, mechanic etc..Such as：Teacher and big-and-middle Pupil's doing mathematics, geometry and little makings or mechanic are required for protractor when measuring drafting and making, existing protractor It is disadvantageous in that；It is not convenient enough to draw angle line, needs first to draw a point, then point is connect with line and could draw an angle again Go out.

Invention content

In view of the above technical problems, the utility model provides a kind of：Angle line can directly be drawn, the angle that draws precisely, just Multi-function protractor prompt, measurement error is small.

In order to solve the above technical problems, the utility model uses following technical scheme：Multi-function protractor, including it is transparent Measurement plate has protractor in the measurement plate, and the protractor is equipped with to be stitched for the setting-out of picture angle line, the protractor Center be that setting-out assists position, setting-out auxiliary position is equipped with the guiding slope for setting-out, the slope that is oriented to Inclined-plane extends to the central point of protractor so that the central point of one end of setting-out seam to protractor.

The advantageous effect of multi-function protractor provided by the utility model is：Due to including transparent measurement plate, the survey There is protractor, the protractor is equipped with to be stitched for the setting-out of picture angle line, and the center of the protractor is setting-out on template Position, setting-out auxiliary position is assisted to be equipped with the guiding slope for setting-out, the inclined-plane amount of extending to for being oriented to slope The central point of angle device so that the central point of one end of setting-out seam to protractor, therefore only need to first finish first when picture angle Line, and protractor is adjusted, so that finish first line is aligned with the angle line needed on protractor, at this time first line and setting-out Angle between seam is exactly to need the angle of picture, and pen tip, which is then inserted into setting-out seam, directly draws, and pen tip can be along It is oriented to slope and is inserted into the central point of protractor picture Article 2 line, the angle to draw directly since the vertex of first line It is more accurate.

Further, the setting-out seam includes that vertical setting-out seam and transverse direction setting-out are stitched, the vertical setting-out seam and laterally picture It it is 90 degree between linear slit, this structure makes picture angle more convenient, especially picture right angle, in the feelings that need not adjust protractor Condition can be finished directly.

Further, the measurement plate is rectangle measurement plate, and the surrounding of the measurement plate is designed with linear measure longimetry scale Line, this structure allows to use when ruler, more convenient to use.

Further, the measurement plate is equipped with parallel lines, and the parallel lines are located at the left side of measurement plate, the protractor Positioned at the right side of measurement plate, what this structure can be more convenient draws parallel lines.

Further, the left side of the measurement plate equipped with cross setting-out stitch, this structure make picture vertical line with it is parallel Line is more convenient.

The utility model will be further described with reference to the accompanying drawings and detailed description.
