Easy to pick up / Ruler

Easy to pick up

The comon ruler we orten used is a thin rectangle. When the ruler drop onto the level surface,it will cling to the ground and difficult to pick it up by hands. This design will change one end of the ruler into a 15 degree Angle can.When the ruler face down, it can be easily picked up,because there is a certain distance between the ruler and the ground .When the ruler face up, press the cant with the figer, because of the leverage, the other end of the ruler tilt and the ruler can also be easily picked up.
