Description
Technical field
The utility model belongs to teaching aid, relates to a kind of multifunctional compass.
Background technology
Compasses are requisite teaching aids in middle and primary schools' teaching process, and student and teacher use.Traditional compasses structure is simple, function singleness, can only draw circle, cannot provide drawn round relevant information, as: radius, circumference and the area of a circle etc.
Summary of the invention
The purpose of this utility model is to provide a kind of multifunctional compass, has the multifunctional compass that structure is simple, with low cost, can provide the features such as the relevant information of drawn circle while drawing circle.
The purpose of this utility model is achieved in that a kind of multifunctional compass, comprises fixed arm and lever arm; Fixed arm top is provided with handle, fixed arm right side edge is carved with gage, on the right side of fixed arm, upper end is provided with bevel protractor, bevel protractor is carved with data scale, fixed arm lower end is provided with compasses point, and fixed arm is provided with compass and level meter, lever arm upper end is fixed on the center of bevel protractor by rotating shaft, lever arm is provided with calculator, and lever arm lower end is provided with paintbrush fixator, and the position of lever arm on bevel protractor is provided with peep-hole.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is the utility model structural representation.
Detailed description of the invention
As shown in drawings, a kind of multifunctional compass, comprises fixed arm and lever arm.
Fixed arm 2 top is provided with handle 1, for operating compasses.
Fixed arm 2 right side edge is carved with gage 4, and on the right side of fixed arm 2, upper end is provided with bevel protractor 8.Gage 4 is for measuring air line distance, and bevel protractor 8 can take measurement of an angle.
Bevel protractor 8 is carved with data scale 9.With this Multi-functional circular programming bowlder, can directly read the data such as drawn radius of a circle, diameter, girth and area by data scale 9.
Fixed arm 2 lower end is provided with compasses point 7, fixes compasses fixed arm 2 for drawing bowlder.
Fixed arm 2 is provided with compass 5 and level meter 6.Can judge direction by compass 5, the levelness can measuring horizontal plane by level meter 6 is gone forward side by side Row sum-equal matrix.
Lever arm 3 upper end is fixed on the center of bevel protractor 8 by rotating shaft, lever arm 3 is provided with calculator 11, and lever arm 3 lower end is provided with paintbrush fixator 10.Lever arm 3 around rotating shaft activity, thus can change drawn radius of a circle.Can correlation computations be carried out with calculator 11, paintbrush fixator 10 can install chalk or pencil.
The position of lever arm 3 on bevel protractor 8 is provided with peep-hole 12.The data on data scale 9 can be read by peep-hole 12 at picture bowlder.
