Abstract
An electrically driven device provided with a housing, an electric motor with a drive shaft having a first rotary axis and a drive pin connected to the drive shaft eccentrically with respect to the rotary axis, and a driven shaft mounted in the housing for performing a pivoting is disclosed. The driven shaft is indirectly coupled to the drive shaft by means of a gear mechanism converting a rotary motion of the drive shaft into a reciprocating pivoting motion of the driven shaft. The gear mechanism comprises one intermediate shaft having a second rotary axis extending in the longitudinal direction of the intermediate shaft and at least one crank arm coupled to the drive pin. The crank arm is pivotably mounted in the housing and is coupled to the intermediate shaft thereby converting a rotary motion of the drive shaft into a reciprocating pivoting of the intermediate shaft about the second rotary axis. The intermediate shaft is coupled to the at least one driven shaft by means of a pivotable bridge such that the intermediate shaft is offset with respect to the at least one driven shaft.
