Zusammenfassung:A pressing and driving mechanism adapted for use with an electric screwdriver, the pressing and driving mechanism including a housing, an output assembly connected to the housing for sliding movement relative to the housing, an anvil coupled to the output assembly for sliding movement therewith relative to the housing and configured to receive rotational impacts, a shuttle coupled to the output assembly for movement therewith relative to the housing, a terminal assembly connected to the shuttle and movable with the same, and a printed circuit board fixed relative to the housing and adapted to be in mechanical contact with the terminal assembly. The terminal assembly and the printed circuit board form a potentiometer with a resistance value that is variable in dependence upon a position of the terminal assembly relative to the printed circuit board.
