发明名称 Tape measure structure with improved brake device
摘要 A tape measure structure includes a tape, an enclosure, and a brake device which further includes a release key and a first and second brake shoes. By means of the above combination, the retraction motion of the tape can be controlled by the user through simply pressing the release key with his finger. It means that the user may pull out the tape to approximately estimated length he desires for measurement without worrying about that tape might automatically bounce back. Then, afterwards, he may press lightly the release key for retracting the tape gradually and stop pressing the release key as soon as the tape reaches to the accurately desired length, the tape will be halted there by the control effect of the brake device.
