The present invention relates to a sophisticated structure for a tape measure wh ich comprising: a measuring tape; a main body; and a brake apparatus, wherein the br ake apparatus includes a plurality of acute teeth; a brake lever and two positioning pins. By the above structure, when using the tape measure, the user may pull out the tape with estimated short est length which assure him of being free from the fear that the tape might wind up abruptly caus ing injury to the user or a third person. The tape measure also can be used to measure successivel y several objects with different lengths by increasing the tape length stepwisely from the shortest to the longest. A more particular structure is provided by the invention that when wind ing up the tape, the user may further pull out a short section of the tape and hold it by hand, t hen tilt the main body in its axial direction with a certain angle and release the tape to perform the withdrawal operation.
