The utility model has the advantages of easy portability, simple structure, easy manufacture, and multiple functions.
Description
Technical field
The utility model belongs to the cultural goods technical field.
Background technology
The ruler of middle and primary schools' use at present can only be drawn straight line mostly, when drawing simple diameter if desired or measuring an angle, must use special-purpose compasses or angle square, if leave behind that a kind of stationery, all hinder use, so waste time and energy when using, last class hour of student need carry inconvenience with a large amount of stationery.
Summary of the invention
The purpose of this utility model provide a kind of easy to use, simple in structure, easy to carry, make simple, a kind of ruler with multiple function.
The purpose of this utility model is achieved through the following technical solutions: a kind of ruler, there is slide-rule dial chi body both sides, are provided with equidistant circular hole in the center of chi body, and are provided with the scale that has stroke vertical line at an end of chi body.The other end at the chi body is provided with 1/4 round angle measuring calibration.Also can make and have angle measuring calibration at the two ends of chi body.
The utility model has the advantages that easy to carry, simple in structure, make easily, and have the advantage of multiple function.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
In the accompanying drawing, 3 is the chi body, and there is slide-rule dial 1 chi body 3 both sides, are provided with equidistant circular hole 5 in the center of chi body 3, and is provided with the scale 6 that has stroke vertical line at an end of chi body 3.The other end at chi body 3 is provided with 1/4 round angle measuring calibration 2.Also can make and have angle measuring calibration 2 at the two ends of chi body 3.When the needs angulation, angle is as requested finished with having angle measuring calibration 2.4 is to draw the vertical line scale in the accompanying drawing; When needs picture semicircle or full circle, to insert corresponding in 0 the hole with a pencil, the length of need selecting again gets final product the picture circle; Also can draw straight line when needing the picture straight line, have the advantage of multiple function.Other does not describe part in detail and is known technology.
