ABSTRACT:
A decoupling mechanism for a power tool having a motor driving a drive shaft that drives a rotating component includes a shaft gear disposed around the drive shaft. The shaft gear has a first side and a second side. The second side has at least one shallow receiving structure and at least one deep receiving structure. At least one friction plate is disposed on the drive shaft adjacent to the first side. At least one pressure plate is disposed on or integrally part of the drive shaft adjacent to the friction plate and configured for rotation with the drive shaft. A spring assembly is biased against the shaft gear. The spring assembly includes a plate disposed around the drive shaft and a spring member. At least one cam is disposed between the plate and the shaft gear, and is configured to engage with the shallow and deep receiving structures.
