摘要： An adjustable ruler includes two elongate ruler members and an adjustable clamping member. Each of the ruler members includes a longitudinal slot, outwardly facing channels along opposite sides of the slot, parallel longitudinal sides, and measuring indicia marked along the parallel longitudinal sides. The adjustable clamping member is received in each of the slots and includes first and second slide members and a selectively releasable connection between the first and second slide members. The slide members have parallel longitudinally extending flanges along opposite sides slidably secured in the channels of an associated ruler member. The releasable connection selectively permits relative pivoting of the slide members about a pivot axis, and includes a biasing member biasing the slide members apart, a threaded screw through the slide members, and a head threaded on an end of the screw to selectively secure the slide members together.
