Abstract

The utility model discloses a multi-functional pointer belonging to teaching aids, which aims at solving the problem that the math teachers of middle and primary school need carrying a pointer, a ruler, a protractor, a compasses, and a laser pen and the like in class . The technical scheme is as follows: two transparent organic glass rulers replace two legs of the compass and are connected through a connecting shaft to form a compass; one of the rulers is connected with a semi-annular protractor through an arc-shaped sliding block to measure the angle of the included angle; a laser pen is internally installed at the top end of the ruler; through the above design, the multi-functional pointer is integrated with the pointer, the ruler, the protractor, the compass, and the laser pen and the like, is convenient to carry, and is mainly used as teaching aids for math teachers of middle and primary school.

Description

Multi-functional teacher's pointer
Technical field:
The utility model belongs to teaching aid.
Background technology:
Teacher's pointer is a lot of at present, but integrates teacher's pointer, ruler, protractor, compasses, laser pen etc., and use and multi-functional teacher's pointer very convenient to carry also do not have.
Summary of the invention:
The purpose of this utility model is to go up class hour in order to solve the school mathematics teacher, need carry teaching aids such as teacher's pointer, ruler, protractor, compasses, laser pen, uses and carry very inconvenient problem.The utility model is made of jointly transparent organic glass ruler, protractor, laser pen switch, coupling shaft, circular arc slide block, laser pen, chalk folder, measurement of angle line etc.; The utility model replaces the two legs of compasses with two transparent organic glass rulers, link together by coupling shaft, form compasses, wherein one connecting a semi-circular protractor by the circular arc slide block on the ruler, be used for measuring the angle of angle, the built-in laser pen in this ruler top by above design, thereby provides a kind of convenient teaching aid that carries that uses that integrates functions such as teacher's pointer, ruler, protractor, compasses, laser pen.
Description of drawings:
Accompanying drawing is a kind of structural representation of the present utility model, in the accompanying drawing the 1, the 2nd, and the transparent organic glass ruler; The 4th, protractor; The 5th, the laser pen switch; The 6th, coupling shaft; The 7th, the circular arc slide block; The 9th, laser pen; The 10th, the chalk folder; 3, the 8th, the measurement of angle line.
Embodiment:
During use, transparent organic glass ruler 1, transparent organic glass ruler 2 overlaped to make teacher's pointer, ruler, laser pen and use; By laser pen switch 5 control laser pens 9; Separately transparent organic glass ruler 1, transparent organic glass ruler 2 can be done the compasses use; The summit of coupling shaft 6 alignment prediction angulations, the both sides of measurement of angle line 3 and measurement of angle line 8 alignment angle can be made protractor and use; Throughput hornwork 4 is done the arc slip on circular arc slide block 7 can measure the obtuse angle.
