A fixing sucker structure including a movable handle, a sucker main body, a controlling inner tube fitted in a tube body of top end of the sucker main body, a lifting thread rod positioned in the sucker main body and screwed with the controlling inner tube and a disc-like enlarged section connected with the bottom end of the lifting thread rod. The circumference of the enlarged section is formed with annular grooves in which soft gaskets are fitted. A gasket with U-shaped cross-section is fitted with the bottom edge of the sucker main body. When the movable handle is rotated, the controlling inner tube is driven to rotate so as to micro-adjust and drive the lifting thread rod to move upward or downward within the sucker main body, creating a vacuum state therein and producing a strong sucking force for firmly attaching the sucker main body to a polished surface such as the outer surface of a car or a glass.
