Description

A multifunctional ruler

technical field

The invention relates to the technical field of stationery, in particular to a multifunctional ruler.

Background technique

Multifunctional ruler is a common stationery item in daily life. The ruler in the market has a single function. General ruler all is to present rectangular shape, is provided with scale at the edge of its surface, can only draw straight line and measure length, and practicability is not high. But these traditional straightedges only have the function of the straightedge itself and do not have additional functions. In actual situations, it is impossible to satisfy people's diverse needs. For example, to draw an angle line, at this moment, it is necessary to use a protractor to achieve such an effect, and the present invention is specifically a multifunctional ruler.

But there are following deficiencies in existing technology:

1. The ruler cannot draw the angle line;

2. The ruler cannot draw all kinds of commonly used graphics;

3. The ruler cannot draw circles with different radii;

4. A ruler cannot draw parallel lines.

Contents of the invention

Aiming at the deficiencies of the prior art, the present invention provides a multifunctional ruler, which solves the problem that the ruler cannot draw angle lines, common figures, circles with different radii and parallel lines.

In order to achieve the above object, the present invention provides the following technical solutions: a multifunctional ruler, including a first ruler body, a second ruler body, and an angle rotation hole, and the first ruler body is connected to the second ruler body through the angle rotation hole , the outside of the angle rotation hole is provided with an angle scale line, the outside of the angle scale line is equipped with a protractor, the first ruler body surface on one side of the angle rotation hole is provided with a plan template, and the plane plan template on one side A bookmark mechanism is installed on the surface of the first ruler body, a pencil support pin is installed on one end of the first ruler body, a stereogram template is provided on the second ruler body surface on one side of the first ruler body, and a stereogram template is provided on one side of the stereogram template side. A pencil pressure mechanism is installed on the surface of the second ruler body, a pencil is installed at one end of the second ruler body on one side of the pencil pressure mechanism, and a double-hole pen cap is sleeved on the outside of the support pin and the pencil, and the double-hole pen cap The surface of the pencil is provided with a pencil placement groove, the surface of the double-hole pen cover on the side of the pencil placement groove is provided with a support pin placement groove, the other end of the first ruler body and the second ruler body is equipped with a rotating shaft, and the rotating shaft The surface is socketed with rubber.

Preferably, the surfaces of the first ruler body and the second ruler body are provided with metric scale marks.

Preferably, the first ruler body and the second ruler body are arranged parallel to each other.

Preferably, a bookmark mechanism is fixedly installed on the surface of the first ruler, and a support pin is welded and installed on one end of the first ruler.

Preferably, a pencil is movably installed at one end of the second ruler body.

The invention provides a multifunctional ruler, which has the following beneficial effects:

(1) The present invention is provided with an angle rotation hole, a protractor, and an angle scale line. The existing ruler only has the functions of drawing a straight line and measuring length, and its practicability is too low. Through the angle rotation hole, the first ruler body and the second ruler body There is a certain angle between them, and the size of the angle can be observed through the angle scale line, which is convenient for drawing the angle line more accurately and quickly, eliminating the trouble of using a separate protractor to draw the angle line, thus effectively solving the problem that the straightedge cannot draw Angle problem.

(2) The present invention uses a variety of graphics in daily learning by setting a planar template and a three-dimensional template. However, a single ruler cannot draw various graphics. In order to avoid this trouble, the present invention By setting the plan template on the surface of the first ruler body and the stereogram template on the surface of the second ruler body, when drawing graphics, you only need to draw a circle on the inside of the template, which greatly reduces the drawing time. , improve the efficiency of learning, and bring convenience to more students, thereby effectively solving the problem that the ruler cannot draw common graphics.

(3) In the present invention, a circle cannot be drawn by a straightedge by setting a support pin, a pencil, and a rotating shaft. The circle is drawn by a compass. The distance between the pencil and the support pin is the radius of the circle. By rotating the pencil with the rotating shaft in hand, the effect of drawing a circle with a compass is achieved. Using the difference in the distance between the pencil and the support needle, the radius of the circle drawn is different, which is in line with the different radii in the study. The circle drawing method effectively solves the problem that the ruler cannot draw circles with different radii.

(4) The present invention makes it impossible to draw parallel lines by arranging the first chi body and the second chi body. In the present invention, the first ruler body is connected with the second ruler body through an angle rotation hole, and the first ruler body and the second ruler body are in a parallel structure in a closed state. If a parallel line needs to be drawn, only the first ruler body and the second ruler body need The ruler body can be closed, which greatly reduces the time for drawing lines, and according to the metric scale lines on the surface of the first ruler body and the second ruler body, the lengths of the two parallel lines drawn are consistent, easy to operate, and simple in structure. And it saves a lot of space, thus effectively solving the problem that the ruler cannot draw parallel lines.
