Description

A kind of multifunctional plotter

Technical field

The utility model relates to mathematics teaching aid technical field, relates in particular to a kind of multifunctional plotter.

Background technology

At present, in teaching, classroom learning process, teacher usually need to draw various figures on blackboard, students also need to be drawn various figures on homework book, and now on market the various drawing instruments such as set square, L-square, ruler, compasses, angle measurement plate, cyclograph be the drawing instruments of simple function, even if there are indivedual multi-functional drawing instruments, but because the shortcomings such as complex structure, operation inconvenience can not get wideling popularize; And existing set square, parallelogram plate etc., can only draw the figure of single angle, bring various inconvenience to the picture work of Faculty and Students.

Summary of the invention

For the problems referred to above, the utility model provides a kind of multifunctional plotter.

The technical solution of the utility model is: a kind of multifunctional plotter, comprises chi arm one, chi arm two, chi arm three, chi arm four, live splint, angle scale, center of circle mouth, rotating shaft; Described chi arm one is connected by rotating shaft with chi arm two-way overwinding rotating shaft connection, chi arm two and chi arm threeway overwinding rotating shaft connection, chi arm three and chi arm four-way overwinding rotating shaft connection, chi arm one, chi arm three, angle scale, center of circle mouth; On described chi arm one and chi arm three, there is a live splint, on chi arm two and chi arm four, have a live splint.

Further, chi arm one, chi arm two, chi arm three and the chi arm fourth class are long.

Further, on chi arm one, chi arm two, chi arm three and chi arm four, all there is scale.

Further, angle scale and center of circle mouth are fixed on the both sides of rotating shaft can not turn, and remaining junction can be around 360 ° of turns of rotating shaft.

Further, live splint comprises slidably folder and movable folder, slidably pressing from both sides and the movable movable port that accompanies a circular hole, can fix pen.

Further, movable folder is connected with folder slidably by movable jig arm, the axis rotation that movable jig arm can be on folder slidably.

Further, center of circle mouth is a circular groove, can fix pen.

Compared with prior art, a kind of multifunctional plotter profile of the present utility model is small and exquisite, conveniently fold, be easy to carry about with one, and can draw respectively straight line, each angle triangle, each angle parallelogram, each angle circular arc, circle, without frequent replacing instrument, there is certain practicality.

Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, the utility model is described in further details.

As Figure 1-4, a kind of multifunctional plotter, comprises chi arm 1, chi arm 22, chi arm 33, chi arm 44, live splint 14, angle scale 7, center of circle mouth 12, rotating shaft 8; Described chi arm 1 and chi arm 22 by rotating shaft 8 be connected, chi arm 22 and chi arm 33 by rotating shaft 8 be connected, chi arm 33 and chi arm 44 by rotating shaft 8 be connected, chi arm 1, chi arm 33, angle scale 7, center of circle mouth 12 connect by rotating shaft 8; On described chi arm 1 and chi arm 33, there is a live splint 14, on chi arm 22 and chi arm 44, have a live splint 14; Chi arm 1, chi arm 22, chi arm 33 and chi arm 44 are isometric and all have a scale; Angle scale 7 and center of circle mouth 12 are fixed on the both sides of rotating shaft 8 can not turn, and remaining junction can be around 8 360 ° of turns of rotating shaft; Live splint 14 comprises and slidably presss from both sides 5 and movable folder 10, slidably press from both sides 5 and movable folder 10 have the movable port 13 of a circular hole, can fix pen; Movable folder 10 by movable jig arm 11 with slidably press from both sides 5 and be connected, movable jig arm can be rotated by the axis 6 on folder slidably.

; Center of circle mouth 12 is circular grooves, can fix pen.

As shown in Figure 1-2, in the time that the movable folder 10 of live splint 14 is stuck on chi arm, chi arm 1, chi arm 22, chi arm 33 and chi arm 44 can not be around the free turns of rotating shaft 8, now can connect pen at the movable port of live splint 14 13 places, by regulating the position that slidably presss from both sides 5, the circle of making all size.Meanwhile, under this state, can make ruler uses.

As shown in Figure 3, in the time that the movable folder 10 of live splint 14 is not stuck on chi arm, chi arm 1, chi arm 22, chi arm 33 and chi arm 44 can be around the free turns of rotating shaft 8, by with the contrasting of angle scale 7, can draw the triangle of each angle, parallelogram etc.
