Abstract
A retractable ruler having positioning and holding function comprises a first element and a second element. A receiving track is formed on the bottom face of the first element. The second element can be received in the receiving tack, and protrudes out of an opening of the receiving track. Scales are disposed at two sides of the surface of the first element. A holding element is positioned on the second element, and protrudes out of a guide track of the first element. The second element is led to move retractably by the holding element. Scales are disposed at two sides of the second element, or the second element forms a knife shape. The guide track is connected, and is separated into several positioning points. The first element can be pivoted with the holding element as a center. The holding element can be held to steadily use the first element.
