Abstract
The utility model relates to compasses which directly measure the distance between two legs, and comprise a freely expandable pencil tip compass leg (2), a pencil tip (1) positioned at the lower part of the pencil tip compass leg (2), a needle tip compass leg (5) and a needle tip (6) positioned at the lower part of the needle tip compass leg (5); the compasses are characterized in that the lower part of the needle tip compass leg (5) is provided with a dial (7); and a draft line (8) used to drive the dial (7) to rotate and count is positioned at the lower part of the pencil tip compass leg (7). According to the technical proposal, the compasses are provided with the radius, so that people can set the size of circles before drawing the circles; in this way, the people can draw the right circles without any length measuring tool, which is very convenient for the users who use the compasses to draw circles. Therefore, the compasses are particularly applicable to home use.
Description
Technical field
The present invention relates to a kind of directly record two foot distance from compasses.
Background technology
At present, people are when using compasses to draw circle, and the distance between the compasses bipod is to utilize other chi tool to measure.Whether can just can obtain the size that compasses will draw circle without measuring with other chi tool, this will bring convenience to people.
For example: when people make troubles for the person of drawing a circle at certain when in particular cases (under the situation without any the chi tool---the probability of happening of this situation is a lot) will utilize compasses to draw circle.
Summary of the invention
The objective of the invention is: propose a kind ofly to allow compasses from strip length (radius) metering device to solve the problem of above-mentioned trouble.
For realizing purpose of the present invention, intend adopting following technical scheme:
The present invention is by the nib compass foot that freely stretches and the nib structure that is positioned at this nib compass foot bottom, and needle point compass foot and the needle point that is positioned at needle point compass foot bottom constitute,
It is characterized in that:
Bottom at the needle point compass foot is provided with dial, affects the draught line of this dial rotation counting to be positioned at the bottom of nib compass foot.
The present invention's characteristics compared with the prior art:
Owing to be provided with the radius size of drawing circle after just can knowing it before drawing circle on the compasses, this has just above-mentionedly brought very big convenience under special circumstances use compasses picture circle person for solving.
Description of drawings
Fig. 1 is the compasses structure charts.
1: the nib structure that forms by nib and location nib mechanism; 2: the nib compass foot; 3: hinge; 4: the compasses handle; 5: the needle point compass foot; 6: needle point; 7: by the dial of rotation counting; 8: across draught line in nib compass foot bottom and needle point compass foot bottom.
The specific embodiment
On the basis of existing compasses structure, owing on needle point compass foot 5, be provided with rotation scale 7, the draught line 8 of dial 7 rotations firmly can be drawn in the location on another nib compass foot 2 of compasses again, when draw back between needle point compass foot 5 and the nib compass foot 2 draw circle apart from desire before, draught line 8 will affect dial 7 rotation, and the angle by rotation on dial 7, demonstrate the circle radius of will drawing apart from size.Obviously, the demonstration of this size does not need to read by other ruler measurement.
