Abstract
The invention discloses a compass. The compass comprises a positioning pin and a movable pin, wherein the movable pin is connected with the positioning pin through a graduated scale; and the movable pin is provided with a refill. The compass skillfully combines the functions of the graduated scale and the compasses together. The compass can solve the problems of inconvenient use and larger drawing scale error of the conventional compass. Meanwhile, the movable pin is movably connected with the positioning pin so as to fulfill the aim of convenient disassembly and storage.
Description
Technical field
The present invention relates to a kind of stationery, be specifically related to a kind of rule and compasses easy to use, that drafting accuracy is high of having.
Background technology
Compasses are to be used for the instrument of picture circle and circular arc.In mathematics and drawing, compasses are used to draw circles or string, are usually used in construction with ruler and compasses.Existing compasses generally include angle and movable pin, and two parts are connected through the hinge, and the distance between angle and the movable pin can adjust.
Along with the needs of study and work, people constantly improve compasses.China Patent No. is 95220454.1 utility model patent " trisection circular curve rule ", the technical scheme that it adopted has very high value at the technical elements of circular curve plotter or analogous instrument, and it has solved the technical problem of curve trisection circular arc effectively.But these compasses still have some deficits, and it does not also solve following problem: need measure radius of a circle earlier with a yardstick when drawing circle, the bipod of compasses opened do the corresponding circle that just can draw after the contrast again on ruler.Existing compasses are the bowlder of radius drawing length-specific, and operation is very inconvenient, and the round scale error of drawing in use is bigger.
Summary of the invention
Goal of the invention:, the invention provides a kind of rule and compasses easy to use, that drafting accuracy is high of having in order to overcome the deficiencies in the prior art.
Technical scheme: for achieving the above object, compasses of the present invention comprise angle and movable pin, and described movable pin is connected with angle by rule, and described movable pin is provided with pen core.
As a kind of preferred version, described rule one end is fixedlyed connected with movable pin, and the rule other end is movably arranged on the angle, and angle is provided with the fixedly buckle of rule.
As another kind of preferred version, described rule one end is fixedlyed connected with fixing feet, and the rule other end is provided with the slide block that can move freely and the fixing button of slide block, and described movable pin is installed on the slide block.
For the ease of carrying, described angle top is provided with draw ring, and described draw ring is installed in the angle top by fine rule.
Beneficial effect: compasses of the present invention, the function with rule and compasses combines dexterously, and compasses use inconvenience, the problem that drawing size error ratio is bigger before can solving; Simultaneously, movable leg is lived with the location leg and is connected, and convenient disassembly is convenient to deposit.
Description of drawings
Accompanying drawing is the structural representation of compasses of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is done further explanation.
As shown in drawings, compasses of the present invention comprise angle 4 and movable pin 1, and movable pin 1 is connected with angle 4 by rule 2, and movable pin 1 is provided with pen core.
In actual production and making, usually rule 2 one ends to be fixedlyed connected with movable pin 1, rule 2 other ends are movably arranged on the angle 4, and angle 4 is provided with the fixedly buckle 3 of rule.In drawing course, when angle 4 was fixed on home position, the radius length of Hui Zhiing is as required regulated rule 2 and is installed in position on the angle 4, and was with buckle 3 that rule 2 is fixing then, draws at last.
In actual production and making, also rule 2 one ends can be fixedlyed connected with angle 4, rule 2 other ends are provided with the slide block that can move freely and the fixing button of slide block, and movable pin 1 is installed on the slide block.In drawing course, when angle 4 is fixed on home position, the radius length of Hui Zhiing as required, the position that adjustment activity pin 1 is installed on the rule 2, that is: adjust slide block to corresponding scale value 2 places, by button slide block is fixed on the rule 2 then, draw at last.
For the ease of carrying, angle 4 tops are provided with draw ring 5, and draw ring 5 is installed in angle 4 tops by fine rule 6.And because movable pin 1 flexibly connects with angle 4, convenient disassembly is convenient to deposit.
The above only is a preferred implementation of the present invention; be noted that for those skilled in the art; under the prerequisite that does not break away from the principle of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
