Abstract
A torque output tool includes an output shaft, a motor, a transmission assembly, and a gearbox. The gearbox is used for accommodating the transmission assembly. The transmission assembly includes a first planetary gearset and a second planetary gearset. The transmission assembly is capable of being switched to a first state and a second state such that the transmission assembly outputs a first gear ratio or a second gear ratio separately, where the first gear ratio is greater than the second gear ratio. When the transmission assembly outputs the first gear ratio, a rotational speed of the output shaft is greater than or equal to 300 r/min and less than or equal to 800 r/min. A length of the gearbox in an axial direction is greater than or equal to 38 mm and less than or equal to 46 mm.
