Abstract
The invention relates to a fixed supporting structure of a crystal ball transmission, comprising a crystal ball, a base, a soft rubber sealed-spigot, a fixed seat and a driven motor, a magnet set, disturbing vane and a fixed disc of decoration and so on installed on above rubber sealed-spigot and fixed seat; characterized in that the rubber sealed-spigot is designed to have a circular sealed-spigot body for sealing the crystal ball opening and a disk-shaped elastic buffer body, wherein, the buffer body further comprises an upper section planar disc edge, a middle section inclined disc edge and a lower section planar disc bottom; and by means of pushing upward a cup-shaped supporting body of the fixed seat and stopping at the buffer body so as to form selected point supporting; when heat expansion and cold contraction are happened due to temperature difference of liquid within the crystal ball, the middle section inclined disc edge of the buffer body will stretch elastically and automatically to absorb the change of volume, by using the upward supporting force of the cup-shaped supporting body under the buffer body to ensure the horizontal position of the fixed disc of decoration un…
