  • HAND TOOL WITH WARNING EFFECT
    Publication number: 20090288526
    Abstract: The present invention provides a hand tool with warning effect. A torque sensor, a music player and a circuit device are disposed in a main body of the hand tool. The circuit device includes a processing unit and a warning sound generator. An operation torque detected by the torque sensor is transmitted to the processing unit. In the case that the value of the operation torque is within a set range, the processing unit shuts off the warning sound generator and the music player can play music for a user to listen to. Once the operation torque of the hand tool becomes greater than the set torque value, the processing unit turns on the warning sound generator to emit a warning signal to alert the user.
