Abstract
The utility model discloses a novel compass, and belongs to drawing tools. The novel compass comprises a straight ruler, a fixed compass rod and a moving compass rod, wherein a rectangular slide way is formed in the middle of the straight ruler, fixing bolts are arranged in positions, with the same height, of the bottom of the fixed compass rod and of the bottom of the moving compass rod, the fixed compass rod and the moving compass rod are fixed on the rectangular slide way of the straight slide way through the fixing bolts, the length of the fixed compass rod is larger than that of the moving compass rod, and rod bodies, located above the fixing bolts, of the fixed compass rod and the moving compass rod are both provided with positioning scales, and a pencil fixing sleeve is arranged on the bottom of the moving compass rod. The novel compass is reasonable in design and convenient to use; and when the novel compass is used, the fixed compass rod is just needed to be adjusted to zero, then the moving compass rod is adjusted to be in a needed scale, then nuts are screwed up, and the moving compass rod and the fixed compass rod are fixed on the straight ruler.
Description
Technical field
The utility model belongs to the stationery field, particularly a kind of novel bow compass.
Background technology
Compasses are a kind of circle tools of often using in people's routine work and the study, present compasses are of a great variety of all kinds, but all form in general by two gauge bars, drawing bowlder need at first use definite good radius such as dimensional measuring instrument such as ruler and then carry out the picture circle, ruler has confirmed that thereby mobile again compasses behind the radius cause two gauge bar variable angle of compasses to cause the variation of radius easily like this, therefore the circle that draws often radius be not inconsistent with required radius of a circle.
The utility model content
Technical assignment of the present utility model is to provide a kind of novel bow compass at above prior art deficiency.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of novel bow compass, comprise ruler, set pattern bar and moving gauge bar, wherein said ruler middle part has the rectangle slideway, described set pattern bar and equal height place, moving gauge bar bottom all are fixed with set bolt, and described set pattern bar and moving gauge bar are fixed on the rectangle slideway of ruler by set bolt.
Further, described set pattern pole length is greater than moving gauge bar length.
Further, be positioned on described set pattern bar and the moving gauge bar on the body of rod on set bolt top and be equipped with the location scale.
Further, be provided with the pencil fixed muffle bottom the described moving gauge bar.
This utility model is reasonable in design, and is simple in structure, easy to use, can determine directly that radius carries out the picture circle.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
With reference to Figure of description the utility model is done following detailed description the in detail:
As shown in Figure 1, a kind of novel bow compass, comprise ruler 3, set pattern bar 1 and moving gauge bar 2, wherein said ruler 3 middle parts have rectangle slideway 6, described set pattern bar 1 and equal height place, moving gauge bar 2 bottom all are fixed with set bolt 5, and described set pattern bar 1 and moving gauge bar 2 are fixed on the rectangle slideway 6 of ruler 3 by set bolt 5.
Further, described set pattern bar 1 length is greater than moving gauge bar 2 length.
Further, be positioned on described set pattern bar 1 and the moving gauge bar 2 and be equipped with location scale 7 on the body of rod on set bolt 5 tops.
Further, described moving gauge bar 2 bottoms are provided with pencil fixed muffle 4.
The bar of will establishing rules during use zeroing is fixed on will be moved the position of gauge bar on ruler then and adjust to the fixing then moving gauge bar in desired location place on the ruler, selected home position can the picture circle.
