ABSTRACT:
A sophisticated structure for a tape measure is disclosed having a measuring tape, a main body, and a brake apparatus, the brake apparatus including a plurality of acute teeth, a brake lever and two positioning pins. A user may pull out the tape with an estimated shortest measuring length which assures him of being free from the fear that the tape might wind up abruptly causing injury to the user. The tape measure also can be used to successively measure different lengths by increasing the tape length from the shortest to the longest. When winding up the tape, the user may further pull out a short section of the tape by hand, then tilt the main body in an axial direction to a certain angle and release the tape to perform the withdrawal operation.
