Abstract
A folding rule includes a first stick having a first hole with a plurality of first protrusions located radially around the first hole. A second stick has a second hole with a plurality of second protrusions located radially around the second hole. A rivet has a resilient member mounted thereto and extends through the first hole and the second hole. The first protrusions are engaged with grooves defined between the second protrusions. The resilient member is compressed so as to disengage the first protrusions on the first stick from the grooves in the second stick. By this way, the first stick is pivoted relative to the second stick.
