<p>The device has three blocking elements (55a-55c) guided into separate channels (56), which are inclined to a plane (E) cutting perpendicular to an axle. The channels cut an axial projection of a switching component, and open into an overlapping region to a switching component (34). The channels run to the axial projection of the switching component according to a type of secant. The channels are distributed around an axle (A), and the switching component is formed in shape of a rod.</p> |
