Abstract
The utility model relates to a scissor style angle gauge, which comprises angle gauges employing a semicircular structure. In each angle gauge, angle scales are arranged on the circular arc edge while semicircular through holes are formed in the middle, and a blade is arranged on the outer side of the straight edge; and the two isometric angle gauges are connected together on a rotating shaft at the middle point of the straight edge. When in use, one edge of an angle to be measured is superposed with a right-angle side of one angle gauge, the sticking point is superposed with the middle point of the rotating shaft, the other angle gauge is rotated, and when the straight edge is superposed with the other edge of the angle to be measured, the angle included between the two straight edges is just the angle of the angle to be measured, so that the angle can be conveniently and quickly read without extending the two edges of the angle to be measured; and the scissor style angle gauge can serve as scissors in normal times. The utility model has the characteristics of simple structure, convenient use, multiple functions, etc.
Description
Technical field the utility model relates to a kind of schooling apparatus, especially a kind of scissor protractor.
The background technology protractor is one of main learning tool of student, when taking measurement of an angle, treat that limit of angulation overlaps with the straight flange of protractor, the summit is positioned at the straight flange center, but often need to prolong another side and just can accurately determine angle, very inconvenient and be easy to cause error, in order to address the above problem, we provide a kind of scissor protractor very necessary.
Summary of the invention the utility model has solved the above problem, and a kind of convenient and practical scissor protractor is provided.
For achieving the above object, the scissor protractor of the utility model comprises protractor, and protractor is a semicircular structure, is provided with angle index on the circular arc limit, and the centre is provided with semicircle open-work, and the straight flange outside is provided with blade; Two big protractors such as grade connect in the rotating shaft of straight flange mid point.
After adopting said structure, a limit for the treatment of angulation can be overlapped with the right-angle side of a protractor during use, the summit overlaps with the rotating shaft mid point, rotate another protractor, when straight flange overlaps with the another side for the treatment of angulation, the formed angle of two straight flanges is the angle for the treatment of angulation, can conveniently read angle, need not to prolong the both sides for the treatment of angulation; Also can be used as scissors at ordinary times uses.
The utility model has the advantages that: simple in structure, easy to use, diverse in function etc.
Description of drawings Fig. 1 is the scissor protractor one-piece construction of a utility model synoptic diagram.
Embodiment as shown in Figure 1, the scissor protractor of the utility model comprises protractor 1, protractor 1 is a semicircular structure, is provided with angle index on the circular arc limit, the centre is provided with semicircle open-work 3, the straight flange outside is provided with blade 2; Two big protractors 1 such as grade connect in the rotating shaft of straight flange mid point.
