Claims

[Scope of utility model registration request]

A tilt/swivel movable base that is a part of a hollow sphere cut out on a flat surface, supports a predetermined device on the cut surface, and has a long hole that includes a swivel shaft insertion part and is aligned with the tilt direction; The tilt/swivel movable base is placed on the edge of the opening at the top, and has a contact portion that is slidably in contact with the external spherical surface of the movable base, and the elongated hole passes through the center of the bottom of the cylinder. A cylindrical protrusion that serves as the center axis of the tilt guide and swivel is provided around the cylindrical protrusion in the same direction in the same direction, and is drilled into the protrusion wall from the outside of the bottom surface to accommodate a portion of the coil spring. A height movable base having a cylindrical jetty portion having a cylindrical cavity and height adjustment teeth provided on the outer wall of the height movable base; A columnar protrusion for guiding, a locking fitting for positioning and fixing at a desired height by engaging with the adjustment tooth, and a coil spring for supporting the open end of the coil spring installed in the cylindrical cavity of the cylindrical projection. A tilt-swivel-height mechanism comprising: a support plate; and a fixed base having a support plate.
