<p>The device has a shaft (2) with a thread (3) attached at a base body (1) for adjusting in a defined distance, where the shaft guides a body (4) into a bore. A spring (5) is guided by the shaft, and a plate (6) is attached at the body. The body and the plate are firmly connected with each other by an adjustment nut (7), and are adjusted forward or backward against pressure of the spring. A vertical rotational plane of the device is spatially separated from a horizontal rotational plane, a left or right movement plane and an upward or downward movement plane.</p> |
