Abstract
The utility model discloses improved compasses belonging to stationery. The utility model consists of two legs. A radius figured scale is arranged between the two legs. Graduated scales and fixing nuts are arranged on the two legs. The device has the functions of the prior compasses and ruler and can draw a circle with a given radius and works as a ruler.
Description
Technical field
The utility model relates to a kind of study article, particularly a kind of circle of any radius that can directly draw, and can be as the modified compasses of ruler use.
Background technology
Traditional construction with ruler and compasses often need be used set square, ruler and compasses etc., carries and uses all extremely inconveniently, particularly must finish jointly with ruler and compasses at the bowlder of drawing certain radius, and the accuracy of mapping is not high again, and troublesome poeration.
Summary of the invention
The purpose of this utility model provides a kind of function that has merged ruler and compasses, and one-object-many-purposes is easy to carry and use, the modified compasses that precision is high.
The purpose of this utility model is achieved in that a kind of modified compasses, comprises rule pin 1 and rule pin 2, is provided with radius dial 3 between rule pin 1 and rule pin 2.On rule pin 1 and rule pin 2, be provided with rule 4 and hold-down nut 5.
Modified compasses provided by the utility model have increased an arc-shaped scale that has the radius scale between the bipod of traditional compasses, therefrom just can directly read the radius of a circle that will draw; Outward flange at the bipod of traditional compasses has increased the length dial, when bipod flare up straight line, can be used as ruler and uses.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation after the utility model launches.
The specific embodiment
The utility model adopts following structure: a kind of modified compasses, comprise rule pin 1 and rule pin 2, and between rule pin 1 and rule pin 2, be provided with radius dial 3.On rule pin 1 and rule pin 2, be provided with rule 4 and hold-down nut 5.
When this device uses, by radius dial 3, can directly read the radius of a circle that will draw, the scale of radius dial 3 is directly to be converted according to the span between the rule pin 1 of compasses and the rule pin 2, radius dial 3 can freely stretch, when the time spent can not draw in.Rule pin 1 and rule pin 2 outward flanges have increased rule 4, when rule pin 1 and rule pin 2 flare up straight lines, tighten hold-down nut 5 fixedly behind the bipod, and bipod has just formed one ruler, has used with regard to working as ruler like this
