Description
[technical field]
The present invention relates to a kind of infrared laser mark quantity hornwork.
[background technology]
Protractor is a kind of drawing tool, and common material is plastics or irony, can draw desired angle as required.Often use together with compasses.
Protractor can draw angle, measuring angle, picture perpendicular line, parallel lines, survey degree of tilt, verticality, levelness, can work as inside and outside right angle and turn chi, open, close up, and can work as length ruler can also comparatively really intuitively read, and draws the circle of given size.Product can be practically applicable to pupils and students by the small-sized stationery of three types processed: A (main material is plastics); Type B teaching aid (main material is plastics) is practically applicable to school teacher; C type instrument (main material is stainless steel metal) is practically applicable to factory, workshop, carpenter, skilled worker, repairman etc.As: teacher, pupils and students' doing mathematics, geometry and little makings or repairman needing carrying amount hornwork, set square, ruler, compasses and workman with surveyor's staff when measuring drafting, making, turning chi, estimating the above-mentioned measurers such as table.
Traditional protractor designs and produces reason due to it, only can measure the angle of standard of comparison, and for the angle that some are larger, inconvenience is measured fast and accurately.
Owing to there are the problems referred to above, be necessary to propose solution to it, the present invention makes just in this context.
[summary of the invention]
Technical matters to be solved by this invention is for above-mentioned deficiency of the prior art, a kind of infrared laser mark quantity hornwork is provided, this infrared laser mark quantity hornwork can measure the size of angle fast and accurately, the numerical value measuring angle is intuitive and reliable, brings great convenience to user of service.
For achieving the above object, present invention employs following technical proposals:
A kind of infrared laser mark quantity hornwork, comprise protractor body, described protractor body is provided with mounting hole, in described mounting hole, is incorporated with rotating shaft, described rotating shaft is provided with can around the infrared laser instrument of described axis of rotation.
Mounting hole described above is located at the intersection of described protractor body central line and zero graduation line.
Infrared laser instrument described above is a kind of infrared laser pen.
Protractor body described above is semicircle shape.
Protractor body described above offers window.
The invention has the beneficial effects as follows:
1, the invention provides a kind of infrared laser mark quantity hornwork, this infrared laser mark quantity hornwork can measure the size of angle fast and accurately, and the numerical value measuring angle is intuitive and reliable, brings great convenience to user of service.
2, among the present invention, mounting hole is located at the intersection of described protractor body central line and zero graduation line, among mounting hole, rotating shaft is housed, rotating shaft is provided with infrared laser instrument, and this setting is convenient to infrared laser instrument and is rotated to each different angles, is convenient to the numerical value quick and precisely taken measurement of an angle.
3, on protractor body, offer window among the present invention, be convenient to save the material making protractor body, alleviate the weight of protractor, be convenient for carrying operation.
[accompanying drawing explanation]
Fig. 1 is three-dimensional view of the present invention.
Fig. 2 is explosive view of the present invention.
[embodiment]
Below in conjunction with accompanying drawing, further detailed description is done to the present invention.
