The invention is composed of an electric 12V-motor 1, the rev reducer 2, the tube 3, the inside shaft 4, the coupling element 6, the tube rings 5, the pin 9, the 30 deg. gears 8, the eccentric shaft10, the head base 7, the connection rod 11, the spherical levers (roll bearings), the combs 13 and the jointed elements 14. The added gears 9 allow the inclination of the head base 7 by 30 deg. as tothe tube 3 while the spherical levers (rolling bearings) 12 reduce the friction and the temperature developed at the head base 7 whereto they are adapted and urge the combs 13 to oscillate from left to right, in an opposite direction to each other. |
