Abstract
The invention relates to a multiple screw driving machine comprising a plurality of individual screwdrivers which are arranged on a body or in a housing (8) and which each comprise a spindle or shaft (7) which is rotatably mounted in the housing and which at an outer front end carries a screw driving tool (10) for engagement with a screw means. Each of the screwdrivers are separately drivable by a common motor (1) via a driving wheel transmission comprising a primary driving wheel (5) for each screwdriver. The primary driving wheel (5) is rotatably but non-displaceably mounted on the shaft (7) of the respective screwdrivers whereas a driver element (14) is non-rotatably but displaceably mounted on the shaft (7) and is displaceable with the aid of an operating means (16) towards and away from the primary driving wheel (5). The primary driving wheel (5) and the driver element (14) each have mating and mutually facing engagement means (19, 20).
