Abstract
The utility model discloses a protractor and especially discloses an electronic protractor. The electronic protractor is characterized in that: an electronic meter is installed on a middle part of a bottom of a protractor body; a measurement disc is installed in the electronic meter; a top of the measurement disc is provided with a needle; a display screen is installed on a front end of the electronic meter; a cell groove is installed on the bottom of the electronic meter; a switch is installed on a right side of the cell groove. The electronic protractor has an advantage that: by using the electronic protractor, students can accurately measure an angle and an error can be avoided so that convenience can be brought for the learning of the students.
Description
Technical field
The present invention relates to a kind of protractor, particularly a kind of amount of electrons hornwork.
Background technology
Students use amount hornwork is measured geometric angle number; General protractor is simpler and easy, and the scale numeral on the protractor is less, thereby the scale that regular meeting misunderstands on the protractor during students causes the measurement mistake; Influence result of calculation, influenced students study.
Summary of the invention
The present invention provides a kind of amount of electrons hornwork that can make things convenient for students to use in order to remedy the defective of prior art.
The present invention realizes through following technical scheme:
The amount of electrons hornwork is characterized in that: the angulation body is equipped with electronic measuring device in the middle of the bottom, is equipped with in the electronic measuring device and measures dish; Measure the dish top pointer is housed; The electronic measuring device front end is equipped with display screen, and battery case is equipped with in the electronic measuring device bottom, and switch is equipped with on the battery case right side.
The invention has the beneficial effects as follows: this amount of electrons hornwork, be fit to each student and use, easy to use, help effectively study accurately take measurement of an angle, avoided error, study brings a lot of convenience to students.
Description of drawings
Below in conjunction with accompanying drawing the present invention is further described.
Accompanying drawing 1 is the structural representation of amount of electrons hornwork of the present invention
Among the figure, 1 angulation body, 2 electronic measuring devices, 3 measure dish, 4 pointers, 5 display screens, 6 battery cases, 7 switches.
Embodiment
Accompanying drawing is a kind of specific embodiment of the present invention.This invention amount of electrons hornwork; It is characterized in that: electronic measuring device 2 is housed in the middle of angulation body 1 bottom; Be equipped with in the electronic measuring device 2 and measure dish 3, measure dish 3 tops pointer 4 is housed, electronic measuring device 2 front ends are equipped with display screen 5; Battery case 6 is equipped with in electronic measuring device 2 bottoms, and switch 7 is equipped with on battery case 6 right sides.This invention amount of electrons hornwork is opened switch 7 during use, electronic measuring device 2 starts; Angulation body 1 base is overlapped as basic limit with the base at measured angle, and moving hand 4 overlaps pointer 4 with the another side at measured angle; Pointer 4 is an angulation with measuring dish 3; Its angle number is the number of degrees at measured angle, and electronic measuring device 2 is presented on the angle numeral on the display screen 5, and students checks that this angle numeral carries out answer and get final product.
