Abstract
The utility model discloses a protractor which comprises a straight ruler body. Straight ruler scales are arranged on the straight ruler body. A semi-round ruler body is arranged on the straight ruler body. An arc groove and a semi-round hole are formed in the semi-round ruler body. Scales are arranged on a position, adjacent to the arc groove, of the semi-round ruler body. A rotation ruler is hinged to the straight ruler body. A round hole is formed in the rotation ruler. When the protractor works, the round hole is used for determining an angle. The rotation ruler is used for drawing lines and the arrangement of the semi-round hole facilitates line drawing. With a hanging rope part, the protractor can be conveniently hung up. The angle can be conveniently determined with the scales. The protractor is simple in structure and can be used for conveniently drawing angles and lines.
Description
Technical field
The utility model relates to a kind of stationery, specifically relates to a kind of protractor.
Background technology
Traditional protractor is semicircular structure, simple structure, and in use, after needing to determine angle earlier, the straight portion of use amount hornwork carries out setting-out then, and troublesome poeration has reduced learning efficiency.
Summary of the invention
Problem to be solved in the utility model provides a kind of protractor, this protractor can draw easily straight line and angle.
For addressing the above problem, the technical scheme that the utility model adopts is:
A kind of protractor, comprise the ruler body, the ruler body has the ruler scale, described ruler body is provided with semicircle chi body, have deep-slotted chip breaker and semi-circular hole on the described semicircle chi body, described semicircle chi body is provided with scale near the position of deep-slotted chip breaker, and described ruler body is hinged with rotary ruler, has circular hole on the described rotary ruler.
As further improvement:
The ruler body is hinged by jointed shaft and ruler body, and jointed shaft is arranged on the home position place of semicircle chi body.
Be connected with lanyard spare on the described ruler body, described lanyard spare has the lanyard hole.
The diameter in described lanyard hole is 5 millimeters.
During work, determine angle by circular hole, then by the rotary ruler setting-out, arranging of semi-circular hole makes things convenient for setting-out, and the utility model is hung in arranging conveniently of lanyard spare up, and angle is conveniently determined in arranging of scale, the utility model is simple in structure, can draw angle and straight line easily.
Below in conjunction with accompanying drawing the utility model is further described.
