Description
Technical field
The utility model relates to a kind of novel angle gauge.
Background technology
The graduation mark of traditional protractor be all table at edge, when needing to measure angle shorter on some limits, need to coordinate ruler to carry out reading, troublesome poeration and precision is not high.When picture angle, need first to draw on one side, amount of movement hornwork carrys out picture another side again, cumbersome, speed is slow, and classmate is in the process of study, needs on textbook, marked class-teaching of teacher by wave emphasis and lime light, therefore classmate needs again the ruler of other waveform groove, so use inconvenience.
Utility model content
The purpose of this utility model is the deficiency overcome in existing product, provide a kind of do not need amount of movement hornwork just can draw angle both sides and structure is simple, easy to use, measure high compared with the precision of minor face, possess the novel angle gauge of the function of picture wave.
In order to achieve the above object, the utility model is achieved through the following technical solutions:
A kind of novel angle gauge, comprise the protractor of semicircle shape, also comprise two pointers, the midpoint of the right-angle side of protractor is equipped with rotating shaft, two pointers are connected with protractor by rotating shaft, and protractor is provided with angle index, and the length of pointer is greater than the length of the right-angle side of protractor, the side being positioned at the pointer of the lower end of rotating shaft is provided with length scale chi, and the opposite side being positioned at the pointer of the lower end of rotating shaft is provided with waveform groove.
Protractor of the present utility model is provided with two manholes.
The top of pointer of the present utility model is provided with semicircular opening.
A kind of novel angle gauge of the present utility model adopts stainless steel material.
The beneficial effects of the utility model are as follows: the utility model is provided with two pointers, the both sides not needing amount of movement hornwork just directly can draw angle are achieved by two pointers, very convenient, angulation is also very convenient, directly by two indicators turn, make the two ends of two pointer alignment angle: the opposite side being positioned at the pointer of the lower end of rotating shaft is provided with waveform groove, the utility model possesses the function of picture wave: because two pointers are connected with semicircular plate by rotating shaft, rotating shaft is positioned at the midpoint of the right-angle side of protractor, solved by the pointer arranged and measure the defect not high compared with minor face inconvenience precision, substantially increase the degree of accuracy taken measurement of an angle, the utility model structure is simple, easy to use: protractor is provided with two manholes, can be used for drawing circle fast: the top of pointer is provided with semicircular opening, angle index can not be covered, make angulation more accurate, this uses novel employing stainless steel material, not easily scratches, long service life.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Detailed description of the invention
Below in conjunction with Figure of description, the technical solution of the utility model is described further:
As shown in Figure 1, a kind of novel angle gauge, comprise the protractor 1 of semicircle shape, also comprise two pointers 3, the midpoint of the right-angle side 12 of protractor is equipped with rotating shaft 3, two pointers 2 and is connected with protractor 1 by rotating shaft 3, protractor 1 is provided with angle index 11, the length of pointer 2 is greater than the length of the right-angle side 12 of protractor, and the side being positioned at the pointer 2 of the lower end of rotating shaft 3 is provided with length scale chi 21, and the opposite side being positioned at the pointer 2 of the lower end of rotating shaft 3 is provided with waveform groove 22.Protractor 1 is provided with two manholes 13, and the top of pointer 2 is provided with semicircular opening 23, and a kind of novel angle gauge of the present utility model adopts stainless steel material.
The utility model is provided with two pointers, is achieved the both sides not needing amount of movement hornwork just directly can draw angle by two pointers, very convenient, and angulation is also very convenient, direct by two indicators turn, makes the two ends of two pointer alignment angle; The opposite side being positioned at the pointer of the lower end of rotating shaft is provided with waveform groove, and the utility model possesses the function of picture wave; Because two pointers are connected with semicircular plate by rotating shaft, rotating shaft is positioned at the midpoint of the right-angle side of protractor, solved by the pointer arranged and measure the defect not high compared with minor face inconvenience precision, substantially increase the degree of accuracy taken measurement of an angle, the utility model structure is simple, easy to use: protractor is provided with two manholes, can be used for drawing circle fast: the top of pointer is provided with semicircular opening, angle index can not be covered, make angulation more accurate: this uses novel employing stainless steel material, not easily scratch, long service life.Pointer is also provided with length scale chi, therefore draw straight line and line segment very convenient, the length of line segment can be measured simultaneously.
It should be noted that above what enumerate is only a kind of specific embodiment of the present utility model.Obviously, the utility model is not limited to above embodiment, can also have many distortion.
In a word, those of ordinary skill in the art's all distortion that can directly derive from content disclosed in the utility model or associate.Protection domain of the present utility model all should be thought.
