Description
Technical field
The utility model relates to a kind of compasses, a kind of easily with the compasses of span function specifically.
Background technology
At present, most compasses all do not have the function of span on the market, draw the circle of a prescribed level, need the length being drawn radius by ruler, depict whole circle with compasses again, if the larger whole process of words of workload is comparatively loaded down with trivial details, be difficult to reach easy effect of drawing circle.
Summary of the invention
The purpose of this utility model is to provide a kind of compasses easily with span function, and can be reached the object of the size determining circle fast by built-in tape measure, convenient use, also reduces workload significantly.
In order to achieve the above object, the utility model is achieved through the following technical solutions:
The utility model is a kind of easily with the compasses of span function, comprise compasses gland, right circles regulation foot frame and left circles regulation foot frame is provided with in the below of compasses gland, right circles regulation foot frame is provided with in the foot rest of right side and stitches, left circles regulation foot frame is provided with in the foot rest of left side and stitches, small-sized tape measure is fixed with by small-sized nut at the middle part of left circles regulation foot frame, the numerical value that small-sized tape measure prints is the twice of full-length, small-sized tape measure is arranged on the middle part of left circles regulation foot frame and is fixed on the middle part of right circles regulation foot frame by the one end after seam pull-out in the foot rest of left side, stitching corresponding reading in the right side foot rest of compasses is drawn radius of a circle.
Further improvement of the utility model is: in the foot rest of left side, seam is positioned at the midpoint of left circles regulation foot frame, stitches the midpoint being all positioned at right circles regulation foot frame in the foot rest of right side.
The beneficial effects of the utility model are: the utility model adds tape measure and reached the object that can measure radius of a circle on the basis of original compasses, tape measure is positioned at the middle part of one end foot rest and the gap pull-out by being positioned at middle part, be permanently secured to the middle part of other end foot rest, open compasses at every turn and just can obtain radius in real time, the non-standard scale of scale on tape measure, but by neutrality line convert drawn by the physical length of radius of circle, tape measure is by middle seam pull-out, and scale surface is the printed material not easily scratched.
The utility model adds small-sized tape measure on the basis of original compasses, thus defines easily and will draw round size, and need not use ruler determination radius, improves operating efficiency, easy to use.
Accompanying drawing explanation
Fig. 1 is the utility model overall structure figure.
Fig. 2 is foot rest side schematic view on the left of the utility model.
Fig. 3 is foot rest front schematic view on the left of the utility model.
Wherein: 1-compasses gland, 2-right circles regulation foot frame, the small-sized tape measure of 3-, stitches in foot rest on the left of 4-, and 5 left circles regulation foot framves, stitch in foot rest on the right side of 6-.
Detailed description of the invention
In order to deepen, to understanding of the present utility model, to be described in further detail the utility model below in conjunction with drawings and Examples, this embodiment, only for explaining the utility model, not forming protection domain of the present utility model and limiting.
As Figure 1-3, a kind of easily with the compasses of span function, comprise compasses gland 1, right circles regulation foot frame 2 and left circles regulation foot frame 5 is provided with in the below of described compasses gland 1, described right circles regulation foot frame 2 is provided with seam 6 in the foot rest of right side, described left circles regulation foot frame 5 is provided with seam 4 in the foot rest of left side, small-sized tape measure 3 is fixed with by small-sized nut at the middle part of described left circles regulation foot frame 5, the numerical value that described small-sized tape measure 3 prints is the twice of full-length, the static friction forces such as the damping of compasses bipod intersection should be greater than the pulling force that small-sized tape measure produces, in use determine the circle of prescribed level easily, described small-sized tape measure 3 is arranged on the middle part of described left circles regulation foot frame 5 and is fixed on the middle part of described right circles regulation foot frame 2 by the one end after stitching 4 pull-outs in the foot rest of described left side, the midpoint that 4 are positioned at described left circles regulation foot frame 5 is stitched in the foot rest of described left side, the midpoint that 6 are all positioned at described right circles regulation foot frame 2 is stitched in the foot rest of described right side, tape measure is arranged in the middle part of left circles regulation foot frame (tape measure end) 5 also by left side foot rest seam 4 pull-out, in the right side foot rest of compasses, the reading of seam corresponding to 6 is drawn radius of a circle.
The utility model adds tape measure and has reached the object that can measure radius of a circle on the basis of original compasses, tape measure is positioned at the middle part of one end foot rest and the gap pull-out by being positioned at middle part, be permanently secured to the middle part of other end foot rest, the reading random length number of degrees of the small-sized tape measure that compasses are equipped with, but the real radius length of the circle obtained that converted by the base that neutrality line and bipod are got continuously, according to conversion stamp on tape measure, tape measure is by middle seam pull-out, scale surface is the printed material not easily scratched, the numerical value that small-sized tape measure prints is the twice of full-length, that is bottom side length is the twice of meta line length, namely the scale that on tape measure, an actual centimeter length place prints is two centimetres, such user is the radius on actual base of measuring from the number that tape measure is read.
The utility model adds small-sized tape measure on the basis of original compasses, thus defines easily and will draw round size, and need not use ruler determination radius, improves operating efficiency, easy to use.
