Abstract: The invention is a rotation direction control structure of electric tools, which includes: a main body with a motor disposed inside; a control unit electrically connected to the motor of the main body and capable of controlling rotational direction and speed of the motor, the control unit is connected to a sensing unit to sense rotational direction and speed of the motor; in addition, the control unit is connected with a switch and a commutation module to control rotation and direction switching of the motor respectively; after the commutation module generates a commutating signal, the control unit drives the motor to decelerate, after the sensing unit detects that a motor speed is zero, the control unit drives the motor to rotate in a opposite direction, and through the commutation module, an electric tool is capable of performing commutating action during operation.
