摘要

The mechanism has a base support (1) i.e. aluminum precision casting part, combining all spring spindles (2) and worm gear shafts (4) produced from light metal or fiber reinforced plastic. The shafts are arranged relative to each other in spread manner such that simultaneously the spindles lie close together, where the spindles are produced from light metal and are bored hollow in a longitudinal direction. Rotary knobs (4.1) are found on a side of a string instrument with an adequate distance from each other. The shafts are arranged in an angle relative to each other.
