Electric power tool

An electric power tool comprising:

• an electric motor configured to output rotation about a longitudinal axis;
• a final output shaft configured to rotate about the longitudinal axis and to which rotation is transmitted from the motor;
• a plurality of operation mechanisms configured to cause the final output shaft to operate in a plurality of predetermined operation modes including at least a first mode configured to cause the final output shaft to vibrate along the longitudinal axis, and a second mode configured to disrupt transmission of rotation between the electric motor and the final output shaft;
• a mode switching member configured to rotate about the longitudinal axis between a plurality of positions, wherein rotation of the mode switching member enable a selecting operation for the plurality of operation modes;
• a transmission mechanism configured to convert the output rotation of the electric motor into a high stage and low stage rotation speed of the final output shaft;
• a speed switching member that enables a selecting operation for the rotation speed between the high and low stage;
• and
• a link unit configured to cooperate with the mode switching member and the speed switching member such that rotation of the mode switching member to a position corresponding to the first mode causes a switching operation of the speed switching member to a position corresponding to the high stage so as to hold the rotation speed at high speed when the final output shaft is configured to vibrate along the longitudinal axis,
• wherein the second mode activates an electric clutch that disrupts rotation transmission of rotation between the electric motor and the final output shaft by de-energizing the electric motor.

An electric power tool comprising:

• a motor,
• a spindle rotated by the motor,
• a hammer being rotatable by the spindle,
• an anvil provide a striking force in a rotational direction by the motor,
• a first cam fixed to the anvil,
• a second cam vibrating the anvil by engaging with the first cam, and
• a mode switching member that is ring-shaped and capable of switching modes among a first mode, a second mode, a third mode and a forth mode,
• wherein the first mode is configured to provide a striking force to the anvil by the hammer, the second mode is configured to enable the first cam to interfere with the second cam, the third mode is configured to enable the anvil to constantly rotate integrally with the spindle, and the forth mode is configured to rotate the anvil integrally with the spindle and to block torque transmission from the motor to the anvil when the torque value reaches the set torque value.
