Control apparatus of impact power tools

The present invention relates to power tools, and more particularly, to the operation of the impact power tool device which can be switched to the intermittent impact mode, screw mode and a drill mode in the impact power tool. An operating device of the impact power tool according to the present invention for achieving the above-mentioned technical problem is by receiving the driving force through the tool axis 210, the motor 100, the motor unit 100 providing a driving force of the power tool operation is disposed between the tool 200, the motor unit 100 and the tool 200 to perform, if a value equal to or greater than the torque transferred to the tool part 200 is set a driving force transmitted to the tool 200 and it is disposed between the blocking torque limit section 300, the torque limit section 300 and the tool 200 to convert a portion of the rotational driving force of the motor unit 100, the axial direction of the tool axis (210) the impact of implementing the to-and-fro movement generating part 400, the torque limit section 300, and the impact generating unit 400, operation unit 500 of a cylindrical shape to regulate the operation of, and the torque limit section 300, and the impact generating unit receiving (400) inside and outside which the operating portion 500 to the outside and coaxially It includes a housing portion 600 for coupling for rotation, and in response to the operation of the operation section 500, a drill mode which limits the operation of the torque limit section 300, and limits operations of the impact generating unit (400) , the operation of the torque limit section 300, enable the operation and limits the operation of the screw mode and the torque limit section 300 for operation of the impact generating unit 400 is limited and unit 400, the impact of the generation of the It characterized in that to switch between the active mode in which the impact.
