Abstract
The utility model relates to novel compasses, and mainly solves the problem that a pen point damages the paper surface in the drawing process of the conventional compasses. The novel compasses comprise a compasses body, a compasses leg and a pen point, wherein the pen point is arranged at the lower end of the compasses leg. The novel compasses are characterized in that: a pen point holder is arranged blow the pen point, and is provided with a concave surface; a pen point hole is formed at the deepest position of the concave surface; a conical space is formed in the pen point holder; the pen point hole is communicated with the conical space; the pen point is inserted into the pen point hole; the upper end and the lower end of the pen point are provided with clamping pieces; and the bottom of the pen point holder is provided with adhesive rubber. Because the pen point holder is arranged on the pen point of the compasses and the pen point is not contacted with the paper surface during drawing or use, the pen point cannot damage the paper surface.
Description
Technical field
The utility model relates to a kind of drawing tools, relates in particular to a kind of novel bow compass.
Background technology
Compasses have become one of important drawing tools of people, thrust the paper center of circle that fixes but existing in the market compasses all are nib when drawing, and so just paper are caused damage in various degree, thereby influence the quality of picture.
Summary of the invention
For the shortcoming and the weak point that overcome background technology, the utility model provides a kind of novel bow compass.Solve existing compasses and have structural disadvantages, during use paper is caused the problem of damaging in various degree.
The technical scheme of the utility model is: a kind of novel bow compass comprises the compasses body, the compasses supporting leg; Nib, said nib is arranged on the lower end of compasses supporting leg, and said nib has the nib frame; Be provided with concave surface above the said nib frame, the bosom of said concave surface is provided with nib hole, and the inside of said nib frame is provided with cone-shaped space; Said nib hole communicates with cone-shaped space; Said nib pierces into nib hole, and the top and bottom of said nib are provided with card, and the bottom of said nib frame is provided with bala gutta.
Being provided with concave surface and the inside of nib frame above the said nib frame, to be provided with cone-shaped space be to cooperate the inclination of compasses nib when drawing to rotate.
The top and bottom of said nib are provided with card, and card is can not come off in the nib hole or move up and down for fixing nib.
The top and bottom of said nib are provided with card, and it is to cooperate the inclination of compasses nib when drawing to rotate that card is taper shape.
It is because bala gutta does not contact with paper and can skid that the bottom of said nib frame is provided with bala gutta, better the fixing center of circle.
The utlity model has following beneficial effect: owing under the compasses nib, be provided with the nib frame; Make people's fixing mode of center of circle employing nib frame when drawing; Thereby nib contacts with paper indirectly, has reduced the damage of nib to paper, thereby has improved the quality of drawing.
Description of drawings
Fig. 1 is the cutaway view of the utility model.
Among the figure, compasses body 1, compasses supporting leg 2, nib 3, card 4, nib frame 5, bala gutta 6, paper 7, cone-shaped space 8, nib hole 9, concave surface 10.
The specific embodiment
Be described further to the embodiment of accompanying drawing below the utility model:
Shown in figure, a kind of novel bow compass comprises compasses body 1; Compasses supporting leg 2, nib 3, said nib 3 is arranged on the lower end of compasses supporting leg 2; It is characterized in that: said nib 3 has nib frame 5, is provided with concave surface 10 above the said nib frame 5, and the bosom of said concave surface 10 is provided with nib hole 9; The inside of said nib frame 5 is provided with cone-shaped space 8, and said nib hole 9 communicates with cone-shaped space 8, and said nib 3 pierces into nib hole 9; The top and bottom of said nib 3 are provided with card 4, and the bottom of said nib frame 5 is provided with bala gutta 6.
Owing to increased nib frame 5 on the compasses, be to draw as long as sharp frame 5 is placed on the center of circle that fixes on the paper 7 at picture.
The above-mentioned description that provides embodiment; So that any technical staff of this area can use or utilize the utility model; Rather than to the restriction of the utility model; The technical staff in relevant technologies field can also make various variations or conversion under the situation of spirit that does not break away from the utility model and scope, so the category that all schemes that are equal to also should belong to the utility model should have each claim to limit.
