[0023] In order to make the technical means, creative features, purpose and efficacy of the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation manner, other embodiments obtained by those skilled in the art without making creative work are all within the scope of protection of the present invention. The experimental methods in the following embodiments, unless otherwise specified, are all conventional methods, and the materials, reagents, etc. used in the following embodiments, unless otherwise specified, can be obtained from commercial channels.

[0024] Example:

[0025] like Figure 1-4 As shown, the utility model provides a flexible folding ruler with a magnetic structure, comprising a ruler body 1, a connecting rod 2 fixedly connected to the left side of the ruler body 1, an end of the connecting rod 2 away from the ruler body 1 is fixedly connected to a gripping end 3, a scale line 4 is fixedly provided on the upper end surface of one side of the ruler body 1, the lower end surface of the ruler body 1 is inclined, the thickness of the lower end of the ruler body 1 is lower than the thickness of the upper end of the ruler body 1, and the ruler body 1 is made of a magnetic material.

[0026] As a preferred embodiment of the flexible folding ruler with a magnetic structure described in the present invention, specifically, in order to better fit the back of the ruler to the surface of an object during use, the back of the scale lines 4 of the ruler body 1 is made into a smooth surface. In this way, when in use, the ruler body 1 can leave fewer gaps so that it can fully fit the surface of the object, and the measurement is more accurate.

[0027] As a preferred solution of the flexible folding ruler with a magnetic structure described in the utility model, specifically, in order to increase diversity, there are several patterns of the hand-grip end 3, so that customers have more choices. In addition, the pattern of the hand-grip end 3 also has an anti-slip effect, which can be conveniently taken up when used as a bookmark; for easy storage, the thickness of the hand-grip end 3 is consistent with the thickness of the scale line 4 of the ruler body 1, so that it can also reduce the space occupied when placed in a pencil case.

[0028] As a preferred solution of the flexible folding ruler with a magnetic structure described in the utility model, specifically, a through hole 5 is opened on the surface of the ruler body 1, and the through hole 5 is in the shape of a rectangle, circle, square or triangle. By providing the through hole in the shape of a rectangle, circle, square or triangle, teachers or students can quickly draw a rectangle, circle, square or triangle when using it, thereby improving drawing efficiency.

[0029] As a preferred solution of the flexible folding ruler with a magnetic structure described in the present invention, specifically, the number of the through holes 5 is set to be several in order to match the length of the ruler body 1 .

[0030] As a preferred solution of the flexible folding ruler with a magnetic structure described in the present invention, specifically, in order to adapt to the diversity of measurements, the scale lines 4 include millimeter and centimeter scales 42.

[0031] The working principle of the utility model is as follows: when it is necessary to measure a certain length of an object, if the surface of the object is an iron object, the ruler can be adsorbed on the surface of the object. Since the ruler has magnetic force, it can be adsorbed on the surface of the iron object, and then the length to be measured can be measured; when using the ruler for drawing, the ruler can be spread out on the surface of the exercise paper. If you want to quickly draw a rectangle, square or triangle of any size, place the through hole 5 of the corresponding shape at the designated position of the exercise paper and then trace it with a pen, which is convenient and fast; when not in use, the ruler can also serve as a bookmark. The end of the ruler away from the scale line 4 is inserted into the book. Because the thickness of the end of the ruler body 1 away from the scale line 4 is lower than that of the end of the ruler body 1 away from the scale line 4, after the ruler is inserted into the book and the book is closed, damage between the pages of the book can be reduced. In addition, the hand-held end 3 is exposed outside the book, which can increase its aesthetics.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
