Abstract

The utility model discloses a simple combined compass which comprises a fixing end, a ruler and a pen, wherein the fixing end is in pencil-shape, the lower end of the fixing end is provided with a cone tip; the ruler is a rectangular long strip ruler, a plurality of circular holes are listed on the surface of the ruler, and the fixing end is inserted into a circular hole arranged at one end of the ruler; the pen is used for drawing circles and is inserted into any other circular hole of the end portions of the ruler. When the simple combined compass is used for drawing a circle, the fixing end is inserted into a hole on the end portions of the ruler to ensure that the cone tip is perpendicular to the plane of paper and therefore the fixing end of the circle center of the compass is formed; when the pen is inserted into another circular hole on the surface of the ruler, the head of the pen is contacted with the plane of the paper and therefore a good circle is drawn by moving the pen. Because the distances between the holes are fixed when drawing the circle and are easy to find, the simple combined compass is applied to drawing circles when the size is fixed and the circles need drawing at high speeds.

Description

The simple combination compasses

Technical field

The utility model relates to a kind of stationery, particularly relates to a kind of simple combination compasses.

Background technology

Similar research situation shows: before this circle tool of invention. people have drawn graceful circle with common compasses, but drawing the super large circle, size is fixing need to draw circle with fast speed very, and at special surface (such as blackboard, glass etc.) during upper drawing circle, do not have to draw smoothly round instrument.

Summary of the invention

In order to address the above problem, the purpose of this utility model is to provide a kind of simple combination compasses.

In order to achieve the above object, the simple combination compasses that provide of the utility model comprise: stiff end, ruler and pen; Wherein: stiff end is the pencil shape, and the lower end has cone centre; Ruler is the rectangular ruler of rectangle, and the chi face is being arranged a plurality of circular holes, and stiff end is inserted in the circular hole of ruler one end; Pen is inserted in all the other arbitrary circular holes of ruler for the pen of picture circle usefulness.

Described pen is pencil, pen or writing pen.

The diameter of circular hole is identical with the diameter of pen on the described straight related scale.

The simple combination compasses that the utility model provides are being drawn bowlder, stiff end is inserted in the ruler end hole, make cone centre perpendicular to paper, this has just formed the stiff end in the compasses centers of circle, pen is inserted in another circular hole on the chi face, contact paper with nib, mobile pen just can draw a very beautiful circle.Because the distance of drawing between bowlder hole and the hole is fixed, and easily find, therefore be suitable for to draw circle with fast speed very in size fixedly the time.

Description of drawings

The composition schematic diagram of the simple combination compasses that Fig. 1 provides for the utility model.

The specific embodiment

Wash in detail bright below in conjunction with the drawings and specific embodiments to the simple combination compasses that the utility model provides.

As shown in Figure 1, the simple combination compasses that provide of the utility model comprise: stiff end 1, ruler 2 and pen 3; Wherein: stiff end 1 is the pencil shape, and the lower end has cone centre; Ruler 2 is the rectangular ruler of rectangle, and the chi face is being arranged a plurality of circular holes, and stiff end 1 is inserted in the circular hole of ruler 2 one ends; Pen 3 is inserted in ruler 2 all the other arbitrary circular holes for the pen of picture circle usefulness.

Described pen 3 is pencil, pen or writing pen.

The diameter of circular hole is identical with the diameter of pen 3 on the described ruler 2 chi faces.

The simple combination compasses that the utility model provides are being drawn bowlder, with the cone centre of stiff end 1 perpendicular to paper, this has just formed the stiff end in the compasses centers of circle, be inserted on the chi face 2 in some corresponding circle holes according to large young pathbreaker's pen 3 of radius of circle, contact paper with nib, mobile pen 3 just can draw a very beautiful circle.Fix because drawing on the bowlder ruler 2 distance between the circular hole and circular hole, and easily find, therefore be suitable for the occasion that to draw circle with fast speed very fixedly the time in size.
