摘要

The top part (9) holding the top jaw of the model is swivel mounted by means of two height-adjustable supports (2) on a link-axis (7) which can be blocked by a screw or screw bolt (1). The top jaw model in the top part can be lowered by the two supports parallel with the lower jaw model in the bottom part (10). The supports are formed by two telescopic sections (2a,2b) and are fixed by a fixture (3) element in their adjusted height. The support section (2a) has a ventilation hole (8). The top part is raised by the force of at least one compression spring (4)
