Abstract: A measuring ruler with self-locking function is presented. The ruler includes a shell and a ruler belt that can be pulled out from the shell. A roller and a shaft body are arranged in the shell, the shaft body connected to the shell. The roller is plugged into the shaft body and rotates along the shaft body to drive the ruler belt. The shaft body includes an inner hollow column which can be elastically deformed in the radial direction. The shaft body interacts with a self-locking column that includes a protrusion area with an increased diameter, the protrusion area extending along an axial direction of the column. When the self-locking column is plugged into the shaft body to a locking position, the protrusion area causes the shaft body to deform and widen in the radial direction, so that the roller is clamped and fixated by the shaft body.
