Description

A kind of statistics special ruler

[technical field]

The utility model relates to a kind of ruler, and specifically the utility model relates to a kind of statistics special ruler.

[background technology]

Known, all need to use some stationery to help learning and handle official business in the daily study and work of people, especially in search, arrange, when analyzing data, the usual form of people, the various chart such as fan-shaped statistical chart carries out simple and clear explanation, and single ruler accurately effectively cannot reach the object making various chart, so in the process making chart, need to use ruler, compasses, drawing assisted by the various stationery such as protractor, the chart made like this could be accurately, specification, but owing to using stationery of a great variety, it is very inconvenient to carry, when go out operation time, often occur due to some stationery of neglected loading and return to the problem of carrying.

[summary of the invention]

In order to overcome the deficiency in background technology, the utility model discloses a kind of statistics special ruler, the auxiliary scale of the utility model by installing on board foot with calipers function, only need carry this kind of stationery at ordinary times and just can reach the object that multiple stationery just can reach, the utility model is convenient for carrying, and uses simple.

Realize the technical solution of the utility model as follows:

A kind of statistics special ruler, comprise board foot, disk, auxiliary scale A and auxiliary scale B, board foot is provided with groove, draw-in groove is provided with in groove on described board foot, central shaft is provided with at the center of disk, one end of described central shaft is connected with disk, and the other end of central shaft is arranged in the draw-in groove in board foot upper groove; Auxiliary scale A is connected with central shaft respectively with the upper end of auxiliary scale B, is provided with chi point in the lower end of auxiliary scale A, is provided with paintbrush in the lower end of auxiliary scale B; The lower half circle of disk is provided with protractor.

Described statistics special ruler, is provided with chuck at the other end of described central shaft, and the other end of central shaft is embedded in the draw-in groove in board foot upper groove by chuck.

Described statistics special ruler, be respectively provided with snap fit in the upper end of described auxiliary scale A and auxiliary scale B, auxiliary scale A is connected with central shaft by snap fit with auxiliary scale B.

Described statistics special ruler, described board foot and auxiliary scale A indicate scale A and scale B respectively.

By above-mentioned disclosure, the beneficial effects of the utility model are:

Statistics special ruler described in the utility model, auxiliary scale that is sharp with chi by two by the central shaft on disk and chi cylinder couples together, during use, just circle can be drawn easily by two auxiliary scales, angle can be obtained like a cork by the protractor on disk, when making chart, slide on board foot by promoting chuck, utilize the scale on board foot and auxiliary scale, just can draw the chart that spacing is identical, line segment is parallel accurately, achieve the object of one-object-many-purposes, avoiding neglected loading stationery when going out affects the problem of work, and the utility model is convenient for carrying.

Fig. 2 board foot structural representation of the present utility model;

Fig. 3 auxiliary scale structural representation of the present utility model;

In the drawings: 1, board foot; 2, groove; 3, draw-in groove; 4, scale A; 5, disk; 6, central shaft; 7, protractor; 8, auxiliary scale A; 9, auxiliary scale B; 10, scale B; 11, chi point; 12, paintbrush; 13, chuck; 14, snap fit.

[detailed description of the invention]

Below in conjunction with embodiment, the utility model is further detailed; The following examples are not for restriction of the present utility model, only realize mode of the present utility model as support, and any equivalent structure in technological frame disclosed in the utility model is replaced, and is protection domain of the present utility model;

The structure provided in 1,2 or 3 by reference to the accompanying drawings, described statistics special ruler comprises board foot 1, disk 5, auxiliary scale A8 and auxiliary scale B9, a kind of statistics special ruler, comprise board foot 1, disk 5, auxiliary scale A8 and auxiliary scale B9, board foot 1 is provided with groove 2, draw-in groove 3 is provided with in groove 2 on described board foot 1, central shaft 6 is provided with at the center of disk 5, one end of described central shaft 6 is connected with disk 5, be provided with chuck 13 at the other end of described central shaft 6, the other end of central shaft 6 embeds in the draw-in groove 3 in board foot 1 upper groove 2 by chuck 13; Respectively be provided with snap fit 14 in the upper end of described auxiliary scale A8 and auxiliary scale B9, auxiliary scale A8 is connected with central shaft 6 by snap fit 14 with auxiliary scale B9, is provided with chi point 11 in the lower end of auxiliary scale A8, is provided with paintbrush 12 in the lower end of auxiliary scale B9; The lower half circle of disk 5 is provided with protractor 7, described board foot 1 and auxiliary scale A8 indicate scale A4 and scale B10 respectively.

Implement statistics special ruler described in the utility model, need picture bowlder, by separating auxiliary scale A8 and auxiliary scale B9, the chi point 11 of auxiliary scale A8 lower end is put on paper, choose suitable distance, the paintbrush 12 of auxiliary scale B9 lower end is touched on paper, rotates board foot 1, picture circle drawing work can be completed; When circle rationally to be separated or is chosen angle by needs, by auxiliary scale A8 and auxiliary scale B9 separately, two inner side edges of auxiliary scale A8 and auxiliary scale B9 separate shape and have a certain degree, and observe the protractor 7 on disk 5 above auxiliary scale A8 and auxiliary scale B9, can choose suitable angle and separate circle; When drawing parallel lines or make form, only need be placed on known line segment by parallel for board foot 1, auxiliary scale is placed perpendicular to board foot 1, the scale A4 on board foot 1 is observed while disk 5 above slip auxiliary scale, the identical form of spacing can be drawn, the utility model achieves the object of one-object-many-purposes, simple and practical, easy to carry.

The non-detailed portion of the utility model is prior art.
