Problems solved by technology

[0002] In school life, when using a marker pen to use a ruler, the contact between the pen tip of the marker pen and the ruler will stain the ruler. After a long time of use, the ruler will be stained, affecting the scale and reducing its lifespan.
On the other hand, it will be difficult to draw long straight lines when the ruler is not long enough

Abstract

The invention discloses a ruler suitable for a marker pen. The ruler suitable for the marker pen comprises a ruler body, rotating shafts, plastic supporting blocks, connecting blocks and rubber wheels; the ruler body is divided into two layers, the thickness of the inner layer is large, the thickness of the outer layer is small, four groove spaces are formed in the ruler body, and the ruler body is connected with the two pairs of supporting blocks and the two pairs of connecting blocks through the rotating shafts; the supporting blocks or the connecting blocks can be contained in the ruler sothat the ruler can stand up parallel to a table top at different heights, and it is guaranteed that a nib smearing area of the marker pen does not make contact with the ruler body to prevent the rulerfrom being contaminated; and meanwhile, the pair of connecting blocks are connected with the pair of rubber wheels, so that the pen clamped on the ruler can move together in parallel, and a longer straight line can be drawn. The ruler suitable for the marker pen has the characteristics of being convenient to use and simple in structure.

Description

technical field [0001] The invention relates to the technical field of learning stationery, in particular to a ruler suitable for marker pens. Background technique [0002] In school life, when using a ruler with a marker pen, the contact between the pen tip of the marker pen and the ruler will stain the ruler. After a long time of use, the ruler will be soiled, affecting the scale and reducing its lifespan. On the other hand, it will be difficult to draw long straight lines when the ruler is not long enough. Contents of the invention [0003] In order to overcome the deficiencies of the above-mentioned prior art, the object of the present invention is to provide a ruler suitable for marker pens, which can be easily propped up to keep the height parallel to the desktop, and can also draw long straight lines. It is practical and convenient, and has the characteristics of simple structure . [0004] In order to achieve the above object, the technical solution adopted by th...
