Angle adjustment stage device for dental technicians

摘要

A base shaft 4 having a built-in magnet is rotatably projected from the base 1. The rocking body 7 has a square substrate 8, a sphere 9, a sphere holder 10 that can rotate around an axis perpendicular to the substrate through the center of the substrate, and a stopper that fixes the sphere holder at a desired rotational position. .. The ball holder holds the ball in a desired rotational position so that it can be fixed. The stage is attached to the ball via the support rod 20. The lower part of the sphere projects downward from the sphere holder and substrate, and the rocking body is magnetically coupled to the base shaft at the lower end of the sphere. The elevating body 21 is fitted into the base shaft and fixed at a desired height position by the set collar 22. The elevating body has a recess that accommodates the lower part of the sphere. The rocking body takes a horizontal position when the lifting body comes into contact with the substrate of the rocking body, but takes an inclined position when the lifting body descends and one side of the substrate is brought into contact with the upper surface of the lifting body. The angle display mechanism 23 for displaying the tilt angle at the tilt position of the rocking body according to the height of the elevating body is provided.
