Abstract

The utility model relates to a safety vacuum fixing device which utilizes a negative pressure detecting device to detect the negative pressure state of the vacuum chamber of the suction cup. When the negative pressure of the vacuum chamber is insufficient, the negative pressure detecting device controls the suction pump to act, so that the suction pump is operated. The exhaust pipe can suck the gas from the vacuum chamber until the negative pressure detector detects that the vacuum chamber reaches a preset vacuum negative pressure value; when the suction cup is adsorbed on the suction surface, the formed vacuum chamber is constantly maintained at a constant time. Good vacuum vacuum suction ensures the safety of the vacuum holder never falling off.
