US Patent 11913545 Power tool with compliant shifting mechanism

A compliant shifting mechanism for a power tool includes a selector, a first shift plate rotatable in response to rotation of the selector, a second shift plate rotatable in response to rotation of the first shift plate, a shift member moveable in response to rotation of the second shift plate to shift between a first mode of operation and a second mode of operation, a first torsion spring coupled to the first shift plate, and a second torsion spring coupled to the second shift plate. In response to rotation of the selector in a first direction, the first torsion spring may bias the first shift plate in the first direction for shifting compliance in the first direction. In response to rotation of the selector in an opposite second direction, the second torsion spring may bias the second shift plate in the second direction for shifting compliance in the second direction.
