Abstract
The utility model relates to a multifunctional folding ruler which is composed of eight straightedges, wherein the eight straightedges are the same in size, every two adjacent straightedges are connected in a rotatable mode through a rotating connecting piece, a through hole is formed in the center of each rotating connecting piece, and scale marks are arranged on each straightedge. Scale grooves are formed in the rotating connecting pieces. Each of two ends of each straightedge and one rotating connecting piece are fixed at a connecting position through a bolt. The multifunctional folding ruler has the advantages that compared with an original tool, the multifunctional folding ruler is convenient to carry and simple and easy to operate; the using method of the multifunctional folding ruler and the using method of the original tool do not have much difference; a needed diagram can be formed through the rotation of the straightedges; needed angles can be determined through the scale marks on the rotating connecting pieces; and the size of an existing angle can also be determined through the scale marks of the rotating connecting pieces.
Description
Technical field
The utility model relates to a kind of multi-functional folding rule.
Background technology
In the conventional teaching, straight line drawn in the ruler term, and set square is used for drawing triangle, and protractor is used for taking measurement of an angle and drawing the angle with certain angle.The effect difference that above-mentioned apparatus plays in actual applications, therefore drawing branch line, angle must adopt corresponding instrument respectively during triangle, therefore student and teacher must use above-mentioned instrument respectively in operation at ordinary times, bring very big inconvenience for student and teacher.
Summary of the invention
The purpose of this utility model is to provide a kind of multi-functional folding rule, by changing the shape of this folding rule, and replaces ruler by the scale groove on the rotary connector, set square, protractor.
In order to realize above purpose, the utility model adopts following technical scheme: this multi-functional folding rule, formed by eight identical rulers of size, it is characterized in that: be rotationally connected by rotary connector between two adjacent rulers, center at rotary connector is provided with through hole, at each ruler scale is set.Rotary connector is provided with the scale groove.Bolting is passed through in the junction of ruler two ends and rotary connector.Advantage of the present utility model is: compare with instrument in the past, have easy to carry, simple operation easily, usage and not too big difference of instrument in the past, required figure is formed in rotation by ruler, determine required angle by the scale on the rotary connector, also the scale of available rotary connector is determined the size of existing angle.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of bolt of the present utility model.
The specific embodiment
With reference to accompanying drawing.This is the function folding rule the more, is made up of eight identical rulers 1 of size, it is characterized in that: be rotationally connected by rotary connector 3 between two adjacent rulers 1, be provided with through hole 4 at the center of rotary connector 3, at each ruler 1 scale is set.Rotary connector 3 is provided with the scale groove.The junction of ruler 1 two ends and rotary connector 3 is fixing by bolt 2.
