Abstract
The invention discloses a ruler which comprises a ruler body. Three grooves are arranged at the center of the obverse side of the ruler body. Each groove is provided with a non-slip pad. The non-slip pads are rubber pads. Due to the fact that the three grooves are arranged at the center of the obverse side of the ruler body, when the ruler is used, a user can place the index finger, the middle finger and the ring finger of one hand in the three grooves. Consequently, the ruler can be fixed so that the ruler can not be easily moved, and the accuracy of drawing line segments and measuring is increased. Meanwhile, each groove is provided with the non-slip pad, and the ruler can not be easily moved in the using process.
Description
