Abstract
The utility model relates to an angle measuring scriber, which comprises an arc flat body plate (1) with an area exceeding that of a semicircle. Angle graduation lines (5) are marked on an arc edge of the flat body plate (1), and a central hole (2) is arranged at a circle enter of the flat body plate (1). A plurality of triangular grooves (3) are arranged on the arc edge of the flat body plate (1), and vertexes of the triangular grooves (3) are positioned at outer ends of part of the graduation lines, and graduation holes (5) are arranged at inner ends of remaining part of the graduation lines. The angle measuring scriber in use can accurately and quickly determine two points of a required angle line and mark the two points, and the angle line can be drawn by connecting the two pints. The angle measuring scriber not only is fast in line drawing, but also has high accuracy.
Description
(1), technical field
The utility model relates to a kind of improved protractor, particularly a kind of protractor of ruling after the angulation be convenient to.Belong to stationery.
(2), background technology
Existing protractor is generally semicircle shape, indicates angle index on the circular arc limit, can measure two angles between the straight line.But when adopting the standing crop hornwork to do angle line, owing to can only draw point near the arc limit graduation mark annex and the protractor center of circle, a stroke some position need be estimated definite, and the degree of accuracy is relatively poor on the one hand, and it is lower to do angle line operating efficiency on the other hand.
(3), utility model content
Technical problem to be solved in the utility model is, a kind of angulation scriber is provided, and can locate really allocation when doing the angle line in the hole (groove) that protractor has a given shape and draw a little, to overcome the defective of standing crop hornwork.
It is as follows that the utility model solves the problems of the technologies described above the technical scheme that is adopted:
A kind of angulation scriber comprises that area surpasses the arc tabular main board of semicircle, indicates the angle index line along the arc limit of this main board, and it is characterized in that: the circle centre position at this main board offers circle center hole; Offer several triangular grooves on main board arc limit, the summit of triangular groove is positioned at part graduation mark outer end; Offer the scale hole in the inner of another part graduation mark.
Good effect of the present utility model is: adopt angulation scriber of the present utility model, can determine 2 of required angle line quickly and accurately and label, can make angle line behind the line.It is fast not only to do linear velocity, and degree of accuracy height.
(4), description of drawings
Fig. 1 is a structural representation of the present utility model.For clear demonstration, the triangular groove and the positioning round orifice that show among the figure are bigger than actual size.
(5), the specific embodiment
Further specify the utility model below in conjunction with drawings and Examples.
As shown in Figure 1, the utility model comprises that area surpasses the arc tabular main board 1 of semicircle, and the requirement that described area surpasses semicircle is that the center of circle in order to ensure arc is positioned on this main board 1.Arc limit along this main board 1 indicates angle index line 5.Circle centre position at this main board 1 offers circle center hole 2.Offer several triangular grooves 3 on main board 1 arc limit, the summit of triangular groove 3 is positioned at part graduation mark outer end.Offer scale hole 4 in the inner of another part graduation mark.
When using the utility model, at described circle center hole 2 places with point of nib point, at the outer end of desired angle index line triangular groove 3 places or inner scale hole 4 place's points more in addition, remove behind the angulation scriber described 2 continuous getting final product.
