Abstract
The utility model is a kind of multifunctional triangle, the isosceles right angle triangle of being made by transparent plastics with and the upper protractor in surface form, it is characterized in that in the round dot of protractor, there is in the heart a rotating shaft, transparent pointer is installed in rotating shaft, convex lens are set in transparent pointer.This multifunctional triangle precision that takes measurement of an angle is high, easy to use, is the student appliance being worthy to be popularized.
Description
Technical field
The utility model is a kind of multifunctional triangle, belongs to school supply and stationery.
Background technology
At present, stationery set square function singleness, on set square, seldom, and it is inaccurate to take measurement of an angle for owning amount hornwork.
Summary of the invention
The purpose of this utility model is to provide a kind of high set square of certainty of measurement with protractor.
The technical scheme that the utility model adopts is: a kind of multifunctional triangle, the isosceles right angle triangle of being made by transparent plastics with and the upper protractor in surface form, it is characterized in that in the round dot of protractor, there is in the heart a rotating shaft, transparent pointer is installed in rotating shaft, convex lens are set in transparent pointer.When need are measured on drawing a certain angle, using round dot center as angular vertex, base is as the initial line that rises at angle, by Wei Zhong limit, limit corresponding to transparent pointer center line, due to convex lens being set in transparent pointer, play magnifying glass effect, scale that can very square observation measured angular.
The utility model beneficial effect is, this multifunctional triangle precision that takes measurement of an angle is high, easy to use, has higher economic benefit and popularizing application prospect.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation
In figure: 1, isosceles right angle triangle 2, protractor 3, rotating shaft 4, transparent pointer
5, convex lens
The specific embodiment:
Below in conjunction with Fig. 1, describe embodiment of the present utility model in detail
Fig. 1 is a kind of multifunctional triangle, the isosceles right angle triangle 1 of being made by transparent plastics with and the upper protractor 2 in surface form, it is characterized in that in the round dot of protractor 2, there is in the heart a rotating shaft 3, transparent pointer 4 is installed in rotating shaft, convex lens 5 are set in transparent pointer 4.When need are measured on drawing a certain angle, using round dot center as angular vertex, base is as the initial line that rises at angle, by Wei Zhong limit, limit corresponding to transparent pointer 4 center lines, due to being set in transparent pointer 4, convex lens 5 play magnifying glass effect, scale that can very square observation measured angular.
