A kind of portable angular bisector drawing machine
Technical field
The present invention relates to a kind of renderer, particularly a kind of portable angular bisector drawing machine.
Background technology
Ruler is the common tool that people study search problem.Through directly measuring with ruler, people can understand the quantitative relation and the shape facility of peripheral things, and combine relevant knowledge and method to solve some the simple practical problems in the life.Especially in art of mathematics, the effect of ruler is outstanding especially, and people usually utilize the ruler mapping or measure, and through the data that directly obtain, comes problem analysis to seek answer.Angular bisector is basic knowledge point in the mathematics; Usually people draw angular bisector and need use compasses simultaneously; Ruler is mapped or is directly measured angle through protractor and drawing angular bisector, though so accurately measurement category is restricted the complex steps of drawing simultaneously; Spended time is inconvenient to carry.
Summary of the invention
Technical problem to be solved by this invention is the defective to background technology, and a kind of portable angular bisector drawing machine is provided, the drawback of tool using when solving the picture angular bisector.
The present invention adopts following technical scheme in order to solve the problems of the technologies described above:
A kind of portable angular bisector drawing machine comprises two rulers, and said two rulers are fixedly connected through circular shaft, on two rulers, generating laser are installed respectively, and said generating laser comprises shift knob, power supply and Laser emission mouth; Connect through lead successively between said shift knob, power supply and the Laser emission mouth.
As a kind of optimal technical scheme of the present invention: said two rulers are the transparent ruler of band scale.
As a kind of optimal technical scheme of the present invention: said generating laser adopts red laser.
As a kind of optimal technical scheme of the present invention: the power supply of said generating laser is a button cell.
The present invention adopts above technical scheme compared with prior art, has following beneficial effect:
(1) generating laser is installed on ruler, the feasible intersection point that can directly find two laser is made angular bisector efficiently, and step is simple, reduces the multiple instrument that uses;
(2) ruler is the transparent ruler of band scale, makes and can directly measure the testee distance, accurately confirms length;
(3) generating laser adopts red laser, makes the clear easy searching intersection point of light;
(4) power supply of generating laser is a button cell, makes power supply stablize and is convenient for changing.

Fig. 2 is the partial schematic diagram of the portable angular bisector drawing machine that designs of the present invention.
Wherein label is explained: 1-ruler, 2-circular shaft, 3-generating laser, 4-shift knob, 5-power supply, 6-Laser emission mouth.
The specific embodiment
Describe below in conjunction with the accompanying drawing specific embodiments of the invention.
Combine shown in Figure 2 like Fig. 1; The present invention has designed a kind of portable angular bisector drawing machine; Comprise two rulers 1; Said two rulers are fixedly connected through circular shaft 2, on two rulers, generating laser 3 are installed respectively, and said generating laser 3 comprises shift knob 4, power supply 5, Laser emission mouth 6; Connect through lead successively between said shift knob 4, power supply 5 and the Laser emission mouth 6.
A kind of portable angular bisector drawing machine of the present invention's design is provided with generating laser 5, and the feasible intersection point that can directly find two laser is made angular bisector efficiently, and step is simple, reduces the multiple instrument that uses.
As a kind of preferred embodiment of the present invention: said ruler 1 is the transparent ruler of band scale, makes and can directly measure the testee distance, accurately confirms length.Generating laser 3 adopts red lasers, makes the clear easy searching intersection point of light.The power supply 5 of generating laser 3 is a button cell, makes power supply stablize and is convenient for changing.
A kind of portable angular bisector drawing machine of the present invention's design is in actual mechanical process, and two inner side edges with ruler 1 overlap with two limits of known angle earlier, and the angle summit of ruler 1 overlaps with known angle fixed point; Identical scale on the relative ruler 1 of centrally aligned of mobile generating laser 5, two generating lasers 5 makes generating laser 5 be positioned at the same distance of relative ruler 1 again; Press the button 4 that opens the light on the generating laser 5, Laser emission mouth 5 emission red lasers are sought the also intersection point of mark two red lasers; Be the point on the angular bisector, the center with known angle links to each other with this point at last, and the straight line that then links to each other is the angular bisector of known angle just; Like this; The portable angular bisector drawing machine angular bisector that both drawn efficiently saves the complex steps of using compasses and ruler again, does not also receive the restriction of measurement category simultaneously.
Combine accompanying drawing that embodiment of the present invention has been done detailed description above, but the present invention is not limited to above-mentioned embodiment, in the ken that those of ordinary skills possessed, can also under the prerequisite that does not break away from aim of the present invention, makes various variations.
