Electrically driven device

An electrically driven device comprising

• a housing (4),
• an electric motor (1) mounted in the housing (4) and comprising a drive shaft (2) having a first rotary axis (I),
• a driven shaft (12) having a second axis (II) and mounted in the housing (4) for performing a movement relative to the housing (4),
• wherein the driven shaft (12) is indirectly coupled to the drive shaft (2) by a gear mechanism comprising a scotch yoke mechanism (5, 7) converting a rotary motion of the drive shaft (2) into a reciprocating motion of the driven shaft (12), wherein
• a drive pin (3) is connected to the drive shaft (2) eccentrically with respect to the rotary axis (I), the scotch yoke mechanism comprises a cross slider (7) having a sliding support (6) which extends perpendicular to the first rotary axis (I) and which receives the drive pin (3) either directly or by a sliding block (5) having a bearing receiving the drive pin (3), wherein the cross slider (7) is axially guided in the housing (4) to be movable in an axial direction perpendicular to the first rotary axis (I) and perpendicular to the extension (III) of the sliding support (6), and
• the driven shaft (12) is coupled to the cross slider (7) by a pivotable crank arm (13), thereby converting a rotary motion of the drive shaft (2) into a reciprocating pivoting of the driven shaft (12),
• wherein the cross slider (7) is displaceably mounted in the housing (4) by at least two stationary bars (8) extending perpendicular to the first rotary axis (I) and perpendicular to the extension (III) of the sliding support (6).
