IMPACT ROTATION TOOL
First Claim
1. An impact rotation tool comprising:
- a drive source that generates power;
an impact force generation unit that generates impact force by changing the power generated by the drive source to pulsed torque;
a shaft that transmits the pulsed torque to the distal tool with the generated impact force;
a torque detector that generates a signal corresponding to the torque applied to the shaft;
a determination unit that determines whether or not a torque value obtained from a signal corresponding to the torque has reached a predetermined torque value; and
a control unit that controls the drive source to a predetermined driving state when the determination unit determines that the torque value has reached the predetermined torque value,wherein the determination unit is arranged on the shaft.

Abstract
An impact rotation tool includes a drive source that generates power. An impact force generation unit generates impact force by changing the power generated by the drive source to pulsed torque. A shaft transmits the pulsed torque to the distal tool with the generated impact force. A torque detector generates a signal corresponding to the torque applied to the shaft. A determination unit determines whether or not a torque value obtained from a signal corresponding to the torque has reached a predetermined torque value. A control unit controls the drive source to a predetermined driving state when the determination unit determines that the torque value has reached the predetermined torque value. The determination unit is arranged on the shaft.
