Abstract (en)
[origin: EP1980371A1] An impact tool (101) comprises a motor (111), a first motion conversion mechanism (113) for converting the rotational output of the motor (111) into a linear motion, a first impact mechanism (117) driven by the first motion conversion mechanism (113) for performing linear motions, a second motion conversion mechanism (115) for converting the rotational output of the motor (111) into a linear motion, a second impact mechanism (119) driven by the second motion conversion mechanism (115) for performing linear motions, and a tip tool member (163) caused by the first and second impact mechanisms (117, 119) to perform alternate impact actions. With these alternate impacts by the first and second impact mechanisms (117, 119), the number of impacts of the tip tool member (163) per unit time is increased, and the first impact mechanism (117) and the second impact mechanism (119) alternatively function as a counter weight.
