Claim:
A suction cup structure that can be attached firmly on a surface of an object comprising: a suction cup; a gel comprising a first surface and a second surface, wherein the first surface is connected to the suction cup; when the suction cup is attached to the object, the second surface is substantially able to attach the suction cup firmly to the surface of the object, wherein the suction cup comprises a protruding portion; the protruding portion and gel delimit a groove, and the groove comprises an adhesive glue liquid to form a tight connection between the protruding portion and the gel, wherein the gel has self-adhesivity, an exhaust portion comprising: a cover portion, which comprises a hole with the cover portion capped on the suction cup; a force-bearing portion, which is penetrated through the hole and connected with the cover portion, and which is in contact with the suction cup; and a force-exerting portion, which comprises a snap ring pivot-linked to the cover portion; the force-exerting portion can exert downward pressure on the force-bearing portion to compress the suction cup and thus forcibly expel the air from the suction cup to reinforce the attaching force of the suction cup.
