The invention discloses an intelligent electric tightening
wrench, which relates to the technical field of fastening
assembly tools and comprises a speed
reducer, a
torque sensor, a direct-current brushless motor, a code scanning module, a color-changing indicating lamp, a display key unit, a driving module, a control module, a
battery pack, a shell, a start-stop key, a reversing key, a lighting piece and a
USB (Universal Serial
Bus) interface, the two ends of the
torque sensor are both of a tooth structure, one end of the
torque sensor is meshed with the shell, the end, away from the shell, of the torque sensor is meshed with the speed
reducer, and the speed
reducer is arranged at the output end of the shell. The electric tool can be powered in a
battery pack mode, a torque sensor, a direct-current brushless motor, a driving module, a control module, a start-stop key, a color-changing indicator lamp and the like are arranged in the electric tool, the electric tool can output quantitative torque to a target bolt, the overall structure is in a pistol shape, and the interior of the tool is divided into the driving module and the control module. The driving module can control execution of the direct-current brushless motor.
