Abstract
The utility model relates to a kind of multi-function protractor, and it is made up of protractor, set square, ruler; Ruler rear end is provided with protractor; Formed semicircle by hollow out in the middle part of protractor, inside is provided with set square, and lower end is provided with rotating shaft.The utility model can either be used for measuring angle, can draw again the angle of certain number of degrees and the straight line of certain length, and structure is simple, easy to use, widely applicable.
Description
Technical field
The utility model relates to a kind of protractor, especially a kind of multi-function protractor.
Background technology
Existing a kind of protractor, its main body is a semi-circle shaped transparent plastic plate, and the middle part of protractor is become semicircle by hollow out, and have deep-slotted chip breaker in the middle part of arc ring, arc ring is divided into EXT scale plate and interior scale plate by deep-slotted chip breaker; Protractor bottom is the strip base plate of level, and the middle part of base plate and the bottom of pointer are rotationally connected, and the top of pointer is positioned on EXT scale plate, and the top of pointer is connected with an abaculus, and abaculus is positioned at deep-slotted chip breaker.Because scale plate is inside and outside two-layer, and middle part hollow out, the angle that the length of side is less can be convenient for measuring, due to the existence of pointer, within the specific limits can as right angle effect, when drawing limit, first that angular metric is good, then fixed pointers top, pointer bar just becomes setting-out ruler and uses.A kind of utility model is also had to disclose a kind of protractor, comprise protractor body, it is characterized in that: described protractor body is provided with one with the pointer of center, described protractor body base for fixed point, the length of described pointer is identical with the radius of described protractor body.
Existing many protractors with pointer, this protractor can only measure angle, but pointer can not be used as ruler, is difficult to see angular vertex clearly at pointer and protractor contact position simultaneously.
Utility model content
In order to overcome the deficiency of above-mentioned standing crop hornwork, the purpose of this utility model is to provide a kind of multi-function protractor, and it adopts and is provided with set square in the inside of protractor, and front end is provided with ruler.
The technical scheme adopted to realize the purpose of this utility model is: a kind of multi-function protractor, is characterized in that: it is made up of protractor, set square, ruler; Described ruler is square shape, and rear end is provided with protractor; Described protractor semi-circular shape, middle part is formed semicircle by hollow out, and inside is provided with set square, and lower end is provided with rotating shaft.
The beneficial effects of the utility model are: it can either be used for measuring angle, can draw again the angle of certain number of degrees and the straight line of certain length, and structure is simple, easy to use, widely applicable.

Detailed description of the invention
In the first embodiment shown in Fig. 1, Fig. 2, Fig. 3, Fig. 4, a kind of multi-function protractor, is characterized in that: it is made up of protractor, set square, ruler; Described ruler is square shape, and rear end is provided with protractor; Described protractor semi-circular shape, middle part is formed semicircle by hollow out, and inside is provided with set square, and lower end is provided with rotating shaft.
In the second embodiment shown in Fig. 1, Fig. 2, Fig. 3, Fig. 4, described protractor is a kind of transparent plastic sheet, and the semicircular arc ring of upper end is designed with scale, and circle centre position is provided with through hole; Described rotating shaft is cylindric, and for a kind of transparent material is made, upper surface is provided with through hole, and coaxial with the through hole of protractor circle centre position, for blocking ruler, ruler can be rotated around the center of circle of protractor, and conveniently can see angular vertex clearly; Described ruler is a kind of transparent plastic sheet, lower end is provided with manhole, and axis is in right side, rear end face is provided with groove, be connected with protractor by rotating shaft, and can disassemble from protractor, for measuring the straight line of different angles and different length or drawing the angle of different angles and the straight line of different length; Described set square is a kind of isosceles right angle triangle, is a kind of transparent plastic sheet, for fast drawing the triangle of 45 degree.
When using the utility model, when requirement angle or when drawing angle, first ruler is enclosed within rotating shaft, angular vertex is put into the circle centre position of protractor, aim at graduation mark just measure angle by rotating ruler or draw angle, when needing the straight line of picture certain length, only ruler need be disassembled and ruler just can be used to draw straight line, structure is simple, easy to use.
