ABSTRACT:
A tape measure of the present invention includes a mounted wheel, a pivot portion, rotation members, transmission wheel and a blade container wherein the rotation members include a first gear and a second gear. The mounted wheel has a serrated portion being arranged around inner sides thereof. The pivot portion being fitted into the opening has an axis and a plurality of posts on a side thereof and a driving bar on another side thereof. The transmission wheel has an operation gear. By the first gear and the second gear respectively and cooperatively operate with the mounted wheel and the transmission wheel, the transmission wheel is therefore rotated four circles as the pivot portion is rotated one circle, so duration of reeling the measuring blade becomes less.
