Abstract
The present invention relates to an eccentric stroke adjusting mechanism for use in a power tool with a principle drive shaft comprising a first and a second eccentric member mounted on the principle drive shaft respectively and a coupling member for connecting the first and the second eccentric member. The principle drive shaft has a central axis. The first eccentric member has a first central axis and the second eccentric member has a second central axis. The eccentric stroke of the first central axis and the second central axis with respect to a central axis of the principle drive shaft is adjustable. The eccentric stroke adjusting mechanism of the invention is reliable and the adjusted eccentricity is non-displaceable. The eccentric stroke adjusting mechanism can be applied to adjust the eccentric stroke of single disk or multiple (e.g., double) disks.
