Description
Technical field
This utility model relates to a kind of statistical means, is specifically related to a kind of precisely stable type statistics drawing instrument.
Background technology
Statistics is by means such as search, arrangement, analytical data, with reach to infer the essence of survey object, the most in advance
Survey the Comprehensive Science that object is following.Wherein use the Professional knowledge of substantial amounts of mathematics and other subject, its use
Scope almost covers social sciences and natural science applied every field.
Statistics development history illustrates: has mathematical statistics after first having Social Statistics, has stochastic variable after first having variable；Society
Meeting statistics is based on variable, and mathematical statistics is based on stochastic variable.Variable and stochastic variable are under certain condition
The mathematical concept that can mutually convert.Social Statistics uses when describing variable, and mathematical statistics is when describing stochastic variable
Use.
Statistical teaching process it is frequently necessary on blackboard draw coordinate axes or circle is divided into some with
Showing the ratio that different materials is shared wherein, owing to not having special instrument, teacher is usually with hands directly on blackboard
Drawing, the figure drawn out is not up to standard, if when particularly circle being divided into stem portion, be usually the distribution directly perceived of teacher, will
Cause distribute on figure inaccurate.It addition, teacher needs to hold drawing instrument when drawing always, slightly offset, can cause and paint
Graph structure is inaccurate, and this, can be the most tired out when causing teacher to draw for the test that teacher is in muscle power and level.
Utility model content
For solving the problems referred to above, this utility model provides a kind of precisely stable type statistics drawing instrument.
For achieving the above object, the technical scheme that this utility model is taked is:
A kind of precisely stable type statistics drawing instrument, operates specific as follows: include fixing crossfoot, flexible drawing ruler, cunning
Road, slide, rotation chi, lever, rotating shaft and circle chi, described fixing crossfoot is provided above slideway, and described fixing crossfoot is by sliding
Road is connected and is provided with slide, and described slide is connected with flexible drawing ruler, and described flexible drawing ruler lower end is provided with
Rotary shaft, described flexible drawing ruler is connected with round chi and two rotation chis by rotary shaft, and described fixing crossfoot one end sets
Being equipped with lever, the described fixing crossfoot back side is provided with Magnet and fixing sucking disk.
As preferably, described round chi and two rotation chis are positioned at the same center of circle.
As preferably, described flexible drawing ruler is moved left and right on fixing crossfoot by slide and slideway.
