[0007] Preferably, a limiting snap ring inclined upward at a certain angle is provided on the outer wall of the gasket. A clamping groove for cooperating with the limiting snap ring is formed on the universal seat, and the limiting snap ring is arranged in the clamping groove.

[0008] The utility model provides a universal suction cup device, which has the following beneficial effects:

[0009] 1.
