The multi-functional ruler has the advantages of complete function, high durability, convenient use and carryover, a little material consumption, low cost, economy and practicality.
Description
Multi-functional scale is a kind of drawing tool that is used to do geometric figure and propaganda pattern.
Existing drawing tool commonly used has: set square, compasses.But they respectively have shortcoming:
1. set square is only made line segment, and carries inconvenience, is easy to damage; 2. compasses can only be drawn circle.
The purpose of this utility model will provide a kind of purposes wide, multiple functional exactly, portably uses conveniently, and is durable in use, and the drawing tool of both economical practicality, can be used to do line segment, circle, special angle.
The utility model is to realize above-mentioned purpose like this: with compasses, ruler closes built in together, both can make line segment, can draw circle again.Fixed head is drawn three line segments respectively in movable pin upper edge, and become 30 ° with the limit of movable pin, 45 °, 60 ° angle.
The advantage that this reality is novel: 1. the utility model is multiple functional, has the repertoire of two set squares, compasses; 2. this reality is novel, and is durable in use, uses easy to carry; 3. the utility model, consumable material is few, and cost is low, and is economical and practical.Accompanying drawing is a structural representation of the present utility model: the graduation mark (6) at ruler plate (1), fixing feet (2), fixed head (3), movable pin (4), securing member (5), angle.
Embodiment of the present utility model: the mathematics teacher, mapping with the utility model on the blackboard or on preparing lessons originally.
Using method of the present utility model: 1. can make line segment with graduated limit; 2. open movable pin, install chalk or pencil and can draw circle; 3. make straight line earlier, open movable pin, certain graduation mark (as 30 ° graduation mark) on it is just all exposed, tightening fastener parts, scale is not had the one side and the aligned of scale, makes straight line along movable pin outside then, get final product the angle (as 30 ° angle) of certain scale.
