Abstract
The invention discloses a multi-functional compass, comprising an eraser, a ruler, a ball point pen, a pencil, a gaging pin, a handsaw, a knife, a protractor and a measuring scale. The multi-functional compass is characterized in that the ruler and the measuring scale share a revolving shaft at one end point, so that angle can be measured by rotating the ruler and the measuring scale; The pencil, the ball point pen share a revolving shaft with the other end of the ruler, when he revolving shaft is rotated, the pencil or the ball point pen can be used; the gaging pin, the handsaw, the knife and the measuring scale share a revolving shaft, and when the revolving shaft is rotated, the gaging pin or the handsaw or the knife can be used. The multi-functional compass of the invention is a multi-functional student utensil and surveying and mapping instrument featuring convenient use.
Description
Technical field the present invention relates to the student and draws and use instrument, directly relates to the student and uses compasses.
Background technology student appliance commonly used at present has ruler, set square, angle square, compasses, a pocket knife, rubber etc., and these instrumental functions are single, cause many inconvenience in the use.
Summary of the invention the present invention will provide a kind of improved compasses exactly, and diverse in function is easy to use, and it can overcome the existing single drawback of drawing instrument effectively.
The object of the present invention is achieved like this: on the basis of original compasses, increased rubber, ruler, ball pen, pencil, rule pin, handsaw, pocket knife, protractor, gage, and easy to use.
As further scheme of the present invention be: two rulers are in end points and protractor totally one rotating shaft, and rotating ruler can take measurement of an angle.
As the further scheme of another kind of the present invention be: the other end of pencil, ball pen and ruler is totally one rotating shaft, rotating shaft can select to use pencil or ball pen, rule pin, handsaw, pocket knife and totally one rotating shaft of another ruler, rotating shaft can select to use rule pin or handsaw, pocket knife.
