Novel structure measuring ruler

The utility model provides a novel structure measuring ruler. The ruler comprises a housing sleeve and a main ruler arranged on one side along the length direction of the housing sleeve. An optical energy conversion module and an energy storing cell, which are connected with each other, are installed in the housing sleeve. A solar photosynthetic plate on the surface of the housing sleeve is connected to the optical energy conversion module. An auxiliary ruler is movably installed in an oblique triangle slide groove in the main ruler. LED lamps connected to the energy storing cell are installed in the main ruler and the auxiliary ruler. The solar photosynthetic plate is used for absorbing light which can be converted into electric energy lightening the LED lights affected by the electric energy conversion module, thereby illuminating the whole ruler face. The scale marks are clear, so limitation on using environment is overcome, environment is protected and energy is saved. The main ruler and the auxiliary rul
