摘要： 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.

摘要： The present invention discloses a clutch mechanism to adjust eccentricity in a power tool. The clutch mechanism comprises an outer race mounted radially on an annular main body which is mounted on an eccentric shaft. At least one first connecting member is disposed between the outer race and the annular main body. At least one second connecting member is disposed between the annular main body and the eccentric shaft. The first connecting member makes the outer race and the annular main body rotate relative to each other at one way. The second connecting member makes the annular main body and the eccentric shaft rotate relative to each other at one way. The annular main body has an axial projection formed thereon to connect with an eccentric mechanism in the power tool. With this type of clutch mechanism, the adjusted eccentricity will not change during working and torque can be transferred stably.
