  • Publication number: 20210031341
    Abstract: This invention provides an electric screwdriver with an integrated torque adjustment and sensing function, comprising a torque sensor connected between an electric motor and a torque adjuster. The torque sensor comprises a transmission shaft connected to the motor shaft by the shaft, a torque sensing component and at least one planetary gear set. The planetary gear set has a torque output component. The transmission shaft transmits the speed reduced rotational force through the torque output component to drive the output shaft to output a target torque which can be adjusted by the adjuster. The torque sensing component senses the operating torque between the transmission shaft and the torque output component of the torque sensor, thereby assembling to improve the problem that the conventional electric screwdriver can only adjust but cannot accurately sense the operating torque.
