[0029] The internal airway is divided into internal airway 1 71, internal airway 2 72, and internal airway 3 73. The internal airway 1 71 starts from the suction cup interface and extends inward to be divided into three. A plug is provided at the middle airway port. Another airway is connected to the pressure regulating valve 11, and another airway is connected to the digital negative pressure sensor 12. The airway is divided into two at the point leading to the digital negative pressure sensor 12, one end of which is connected to the digital negative pressure sensor 12, and the other end extends to the outer shell and is connected to the exhaust port b62 of the three-way solenoid valve 2 6, and a plug is provided at the port near the outer shell.
