1. A sucker base device comprises:
a suction cup, a threaded rod being connected to an upper surface of the suction cup and having a protrusion section exposed outside a top surface of a cup upper cover;
the cup upper cover covering the suction cup, and
a pressure driving nut, which is threaded to the protrusion section of the threaded rod, is supported on the top surface of the cup upper cover, and is allowed to a rotary motion; wherein the suction cup has a connection portion through which the threaded rod is connected to the suction cup, the threaded rod penetrates through a top surface of the cup upper cover, the threaded rod is driven to move by rotating the pressure driving nut, and thus carries the connection portion of the suction cup to lift up towards the cup upper cover, so as to form a negative pressure between the suction cup and a surface of an object; wherein a middle top of the cup upper cover defines a mounting hole through which the threaded rod penetrates, the top surface of the cup upper cover defines an annular groove which is disposed around the mounting hole, a bottom wall defining the annular groove defines two pairs of first blind holes.
