An electric tool for outputting torque includes a housing and a motor disposed in the housing, a rotatable base configured to be driven by the motor to rotate about a first axis, at least one impact block rotatably connected to the rotatable base, an output shaft rotatably connected in the housing and configured to rotate about the first axis under intermittent impact of the impact block, a locking member which, when at a first position, locks the impact block to prevent it from impacting on the output shaft and which, when at a second position, releases the impact block to allow it to rotate freely, a biasing assembly for biasing the locking member to the first position, a regulating assembly for regulating a biasing degree exerted by the biasing assembly on the locking member, and a control assembly operable by the user from outside the housing to control the regulating assembly. The locking member is disposed at least partially in the rotatable base.
