ABSTRACT:
A tape measure with innovated brake structure characterized in that the brake mechanism comprises a release key, a brake, and a stopper. The upper end of the brake is in connection with the release key, and an intermediate protrusion of the brake directly presses its upper end so as to control the stopper able to be tightly pressing the tape surface against a stop block provided thereunder. By the above described structure, the user may press the release key with a finger to retract the extended tape after measurement work has been completed. When the release key is released, the brake actuates the stopper to directly press the tape surface against the stop block thereby halting the tape therebetween and the braking function is thus performed.
