Taking the positive pressure gas output as an example, the relationship between the conducting assembly 546 and the pressure regulating assembly 545 is as follows: the second gas outlet 552 outputs positive pressure gas, and due to the existence of the one-way valve 558, the positive pressure gas enters the pressure regulating assembly 545 through the first conducting piece 556 and enters the second conducting piece 557 through the pressure regulating assembly 545, and at this time, the positive pressure gas is output from the gas outlet piece 544 and the pressure value is measured in real time by the pressure gauge 547; when the positive pressure air pressure value is too large or too small, the positive pressure air pressure can be intuitively reflected by the pressure gauge 547, and the worker can adjust the air pressure through the pressure adjusting assembly 545.

Similarly, when outputting the negative pressure gas, since the negative pressure gas is realized by the gas flowing back to the second gas outlet 552, the gas in the gas outlet 544 enters the second gas outlet 552 through the check valve 558 or the pressure regulating assembly 545, and is discharged from the second gas inlet 550; at this time, the effect of controlling the pressure value of the negative pressure gas can be achieved by controlling the gas passing through the pressure regulating assembly 545.

Preferably, the pressure regulating assembly 545 includes an air pressure regulator 554 and a throttle valve 555, the air pressure regulator 554 is disposed between the first conducting member 556 and the second conducting member 557, and the throttle valve 555 is disposed between the air pressure regulator 554 and the second conducting member 557. That is, the pressure regulating assembly 545 regulates the pressure by changing the cross-section of the throttle 555 or the length of the throttle 555 to control the gas flow. Specifically, the second conducting member 557 is further connected to a pressure gauge 559 for monitoring the pressure of the gas output by the present invention, so as to facilitate timely adjustment.

In conclusion, the invention realizes the effect of outputting positive pressure or negative pressure gas only through one gas source by matching of simple structures, thereby saving the cost and being suitable for the movement or the disassembly and the assembly of fragile products with low cost.
