This second part of the guide is pressed to the first part of the guide with tension spring, which is located outside the space between the posts. Parts of the guide are aligned, their ends in the contact area of two parts of the guide are made converging when approaching these ends. Tapered part of these zones of guide parts represents, for example, truncated cone, or part of surface of sphere, or other surface, at that that part of guide, which is pressed by tension spring, moves along its axis. End part of this second part of the guide passes through the hole in the second post, which is rigidly fixed to the base. End part of the second part of the guide extends beyond the limits of the second post and is connected by means of other parts to the second end of the extension spring. Zone of contact of the ends of the guide is located between the posts approximately at equal distance from the posts.
