Abstract
The utility model relates to a multifunctional teaching ruler. The ruler comprises a main ruler, wherein one end of the main ruler is hinged with a subsidiary ruler, and the other end of the main ruler is provided with a first protractor; one end, which is hinged with the main ruler, of the subsidiary ruler is provided with a second protractor, the main ruler is provided with fixed clips for fixing the subsidiary ruler, and the fixed clip is provided with a handle. The ruler provided by the utility model has the advantages that when the ruler is used, the first protractor is used for measuring an angle, the subsidiary ruler is rotated, straight lines with different dip angles are drawn; after the ruler is used, the subsidiary ruler is fixed through the fixed clips; the ruler is variable in functions, easy to carry and convenient to use.
Description
Technical field
The utility model relates to a kind of teaching aid, relates to specifically a kind of multifunctional teaching gauge.
Background technology
Traditional ruler normally includes the blade of strip, on blade, is provided with scale, utilizes scale to measure size.In teaching process, usually need to carry out by ruler the straight line of picture all lengths, because the function ratio of ruler is more single, when graphing, multiple types of tools need to be used in combination, so just need to use multiple types of tools, as ruler, set square, protractor etc., carry very inconvenient, in drawing course, need to change one by one or many are used in combination, very inconvenient.
The utility model content
Problem to be solved in the utility model is to provide a kind of diverse in function, is easy to carry about with one, teaching gauge easy to use.
For addressing the above problem, the technical scheme that the utility model adopts is: a kind of multifunctional teaching gauge, comprise main scale, the end of described main scale is hinged with secondary chi, the other end of described main scale is provided with the first protractor, the hinged end of described secondary chi and main scale is provided with the second protractor, on described main scale, is provided with the geometrical clamp of fixed joint chi, is provided with handle on described geometrical clamp.
A kind of concrete prioritization scheme, described main scale and secondary chi are by bolted splice.
A kind of concrete prioritization scheme, the quantity of described geometrical clamp are two.
The utility model is taked above technical scheme, has the following advantages: during use, can to angle, measure by the first protractor, and can the revolute chi, thereby can draw the straight line of different angle, after finishing using, secondary chi is fixed by geometrical clamp, diverse in function, be easy to carry about with one, easy to use.
The accompanying drawing explanation
Accompanying drawing 1 is the structural representation of a kind of multifunctional teaching gauge in the utility model embodiment;
Accompanying drawing 2 is the top view of accompanying drawing 1.
In figure:
The 1-main scale; The 2-geometrical clamp; The 3-handle; 4-the second protractor; The secondary chi of 5-; The 6-bolt; 7-the first protractor.
The specific embodiment
Embodiment: as shown in Figures 1 and 2, a kind of multifunctional teaching gauge, comprise main scale 1, one end of described main scale 1 is hinged with secondary chi 5, the other end of described main scale 1 is provided with the first protractor 7, the hinged end of described secondary chi 5 and main scale 1 is provided with the second protractor 4, on described main scale 1, is provided with the geometrical clamp 2 of fixed joint chi 5, is provided with handle 3 on described geometrical clamp 2.
Described main scale 1 is hinged by bolt 6 with secondary chi 5, after adjust the position of main scale 1 and secondary chi 5, and can be fixing by bolt 6.
The quantity of described geometrical clamp 2 is two, can increase as required or reduce the quantity of geometrical clamp 2.
