Abstract
An intermittent stop device for tape measures includes a gradually raised gill portion provided at a side edge of a top portion of the housing of a tape measure. The gill portion is adapted for pressing by a thumb. The gill portion has a central through hole which allows a stop switch to pass through to be exposed on the outside. The stop switch has a base pad capable of contacting one side of a reel inside the tape measure to achieve a frictional stopping function. A lock switch may be provided at the top portion of the housing to position the reel. The gill portion is located at a side edge of the top portion of the housing near the lock switch so that the stop switch is near the lock switch to facilitate pressing by the user with his thumb. Additionally, a stop block may be provided at the inner wall of the housing relative to the stop switch to support the reel wheel when the latter is subject to a side pressure and to achieve a frictional stop function to prevent the reel wheel from becoming eccentric. In addition, a pivot bolt is centrally disposed inside the housing. One end of the pivot bolt is engaged with a screw passing through the center of the housing so that the outer…
