Abstract

A power tool includes a motor having a motor shaft, a first intermediate shaft, and a second intermediate shaft extending in parallel to the first intermediate shaft. An output shaft removably holds a tool accessory and has a driving axis extending in parallel to the first and second intermediate shafts. A motion-converting mechanism converts rotation of the first intermediate shaft to linearly hammer the tool accessory. A rotation-transmitting mechanism transmits rotation of the second intermediate shaft to rotate the output shaft. A rotational axis of the motor shaft intersects, or is skewed relative to, the driving axis. A pair of first gears, e.g., bevel gears, operably couples the motor shaft to a first one of the first and second intermediate shafts. A pair of second gears operably couples the first one of the first and second intermediate shafts to a second one of the first and second intermediate shafts.
