ELECTRICALLY POWERED TORQUE-CONTROLLED TOOL

摘要

This tool has a switch(7) for stopping and starting the electric motor(6) and a torque cut-off mechanism that acts on the switch. A clutch(44) is installed between the motor and the bit holder(47) to interrupt the transmission of rotation between the two. The torque applied to the workpiece through the bit reaches a pre-set torque. the motor is rotated only when necessary, reducing the noise and prolonging the life of the brushes.
