Through the satellites 9 one of the salt wheels 10 or 13 is set in motion (depending on which of them is slowed down by the dog 20, i.e. which movement is chosen). If the sun wheel 10 is inhibited, then the rotation is transmitted by the sun wheel 13 and, through the roar L6- “and the sleeve 7, rotates. Privo carries out rounding. If the sun wheel 13 is inhibited, the sun wheel 10 rotates, and the fingers open in the hand mechanism after rotation of wheel 12. When the lever; 16 is applied to the microswitch 19, the inverter is reversed and is carried out (reverse movements are performed. When attenuating m (pi 6, the spring 17 returns the lever 16 to the initial position and the drive stops.) the switch 25 switches. In this motion, the crawler 132 through the connecting rod 21 t does not have the right upward 20. Upwardly, the pin 26 meets the elastic plate 28. The force on the load increases to overcome the elastic force of the plate. A plate sufficient for the passage of the pin 26, the tolzun 22 breaks down and the dog 20 under the action of inerdionic forces turns 1 on the axis to the other side and places the sector 14 of the sunwheel 13 on the backplate. 27, the plate 28 and it, after passing the pin, is attracted to the support 29 by a weak spring 30. The same mechanism is operated to switch the drive to another mechanism. Such a control scheme allows the use of a muscular source of a disabled person with an amplitude of movement for switching mechanisms, and using a powerful and adequate source, such as bending a shoulder stump, for controlling functions using electric drives. Claims of drive mechanisms of elbow and brush, containing (housing, electric motor, gearbox, differential, sun wheels of which are connected respectively with mechanisms of elbow and brush, t yu, control unit 1 of mechanisms, and switching unit, characterized in to control and increase the reliability of operation, the switching unit is designed as a rocker to fix both sun wheels of the differential, and the control mechanisms are equipped with microswitches and a control voltage. .f.f -fff-fff /JV ./ Jv. 2525
