Abstract
A power tool includes a housing, a motor, a ball sleeve, an oscillating member with a mounting portion, and an output shaft rotating around an output shaft axis. The oscillating member and the ball sleeve are engaged in an engagement region on the oscillating member, and the geometric center of the engagement region is an engagement center. A first plane bisects the first bearing assembly along a direction of the output shaft axis, and a second plane bisects the second bearing assembly along the direction of the output shaft axis. The height from the engagement center to the first plane is a first height H1, the height from the engagement center to the second plane is a second height H2, and the ratio H1/H2 of the first height H1 to the second height H2 is greater than or equal to 0.5 and less than or equal to 1.4.
