Description
Technical field
The present invention relates to compasses field, in particular to a kind of compasses of adaptive paintbrush.
Background technique
Compasses are in mathematics and drawing, for drawing a kind of tool of round or arc.Currently, compasses mostly structure in the market
It is single, it can only realize the function of picture circle, and the radius of drawn circle is generally required to have by other rulers and could be obtained.
The Chinese invention patent of Publication No. CN106945435A discloses a kind of multifunctional compass, determines although it has
The function of circle size is drawn, but its size adjustment structure depends on compass leg, not only makes the overall structure of compasses complex, and
More using being limited, it is not convenient enough to use.
In addition, the stitch of existing compasses often damages paper, after repeatedly drawing circle, paper is generally difficult to carrying out book
It writes.
Meanwhile common compasses are that picture circle is carried out using pencil-lead, but in many instances, it is also necessary to pencil-lead
The circle drawn is painted with other paintbrushes, retouches the subsequent processings such as side, to cannot directly be carried out using various types of paintbrushes
It draws and justifies, and the circle handled by hand, inevitably there is deviation from circular from.
Summary of the invention
The radius of picture circle cannot flexibly, be easily adjusted for compasses of the existing technology and can damage paper, no
The problem of various types paintbrush can be used, the purpose of the present invention is to provide a kind of compasses of adaptive paintbrush.
To achieve the above object, the technical solution of the present invention is as follows:
A kind of compasses, including annulus ontology, revolving part and locating piece, it is recessed that the inner sidewall of the annulus ontology is equipped with annular
Slot；The revolving part is rotatably connected on annulus ontology by the annular groove, the pivot center annulus sheet of the revolving part
The axis of body is overlapped；The revolving part is equipped with sliding slot, and the sliding slot is arranged radially along the annulus ontology, on the sliding slot
Equipped with sliding block compatible with the sliding slot；On the slide block, the locating piece includes self-centering card for the locating piece installation
Disk, the self-centering chuck and annulus ontology coaxial line, the sliding block are equipped with lock-screw；It further include flexible scale, it is described to stretch
One end of contracting scale is hinged on the revolving part, the other end is hinged on the self-centering chuck, the flexible scale and circle
The axis of ring body, the axis of self-centering chuck intersect vertically.
Preferably, the annulus ontology includes two semicircular rings, and described two semicircular ring one end are hinged by pin shaft, and two
The semicircular ring other end is connected by tight locking button.
Further, the side wall of the annular groove is equipped with annular positioning groove, and the revolving part is equipped with and the ring
The compatible locating piece of shape locating slot.
Preferably, the lock-screw is hand screw.
Preferably, the self-centering chuck is scroll chuck.
Preferably, axis of the pin shaft perpendicular to the annulus ontology.
Preferably, the initial scale value of the flexible scale is equal to the half of the self-centering chuck outer diameter.
By adopting the above technical scheme, due to the setting of the annulus ontology of annular, so that stitch can be omitted, it can be effective
Prevent damage of the compasses to paper；The setting of revolving part and flexible scale enables the radius for drawing circle directly to measure, does not need
By other tools；The setting of self-centering chuck included by locating piece, so that the paintbrush of different-diameter can be directly placed into
Wherein use；The setting of lock-screw, enables locating piece to be locked, and prevents picture circle from deviation from circular from occur.

Specific embodiment
Specific embodiments of the present invention will be further explained with reference to the accompanying drawing.It should be noted that for
The explanation of these embodiments is used to help understand the present invention, but and does not constitute a limitation of the invention.In addition, disclosed below
The each embodiment of the present invention involved in technical characteristic can be combined with each other as long as they do not conflict with each other.
As shown in Figure 1-3, a kind of compasses, including annulus ontology 1, revolving part 2 and locating piece, the inner sidewall of annulus ontology 1
It is equipped with annular groove 4；Revolving part 2 is rotatably connected on annulus ontology 1 by annular groove 4, the pivot center circle of revolving part 2
The axis of ring body 1 is overlapped；Revolving part 2 is equipped with sliding slot 5, and sliding slot 5 is arranged radially along annulus ontology 1, sliding slot 5 be equipped with
The compatible sliding block 6 of sliding slot 5；Locating piece is mounted on sliding block 6, and locating piece includes self-centering chuck 3, self-centering chuck 3 and circle
