[0050] ① When the circular turntable 91 is in the first state, the input inner channel 92 is connected to the second connection hole 53, and the first connection hole 48 is closed.

[0051] ② The stepper motor drives the circular turntable 91 to rotate 180° clockwise, and the circular turntable 91 will be converted into the second state. At this time, the input inner channel 92 is connected to the first connection hole 48, and the second connection hole 53 is closed.

[0052] ③ The stepper motor drives the circular turntable 91 to rotate 180° counterclockwise, and the circular turntable 91 will be converted back to the first state; the clockwise and counterclockwise rotation can prevent the input pipe 93 from being entangled.

[0053] ④ Install the pressure sensor 24; the circular turntable 91 is in the second state driven by the stepper motor; then, the external placed air pump adds gaseous medium to the input pipe 93, and the gaseous medium will be introduced into the spacing cavity 47 after passing through the first connecting hole 48, pushing the second translation follow-up block 43 to move outward, and then pushing the translation slider 41 to hide in the translation inner cavity, so as to avoid the translation slider 41 hindering the installation of the pressure sensor 24.

[0054] ⑤ Insert the pressure sensor 24 into the main vertical socket 22, align the positioning protrusion 211 with the positioning recess 244 to ensure that the position of the translation slider 41 corresponds to the side locking concave surface 242; the detection contact 241 of the pressure sensor 24 will pass through the secondary vertical socket 23 and extend into the vertical access hole 18.

[0055] ⑥ Turn off the external placement air pump, and the translation slider 41 extends into the side locking concave surface 242 under the elastic force of the first translation spring 45 to lock the pressure sensor 24.

[0056] ⑦ Improve the contact sealing between the secondary vertical jack 23 and the detection contact 241; the circular turntable 91 is in the first state under the drive of the stepper motor; then, the external placement air pump adds gaseous medium to the input pipe 93, and the gaseous medium will be added to the second connection hole 53, and then continuously push the sealing slider 61, and enter the second inner opening 52 and the first inner opening 51. The gaseous medium will eventually squeeze the rubber sealing ring 50, so that the rubber sealing ring 50 and the detection contact 241 are tightly attached, thereby improving the contact sealing between the rubber sealing ring 50 and the detection contact 241 and preventing leakage of the fluid medium.

[0057] ⑧ Turn off the external placement air pump, and the sealing slider 61 will extend into the sealing recessed groove 63 under the elastic force of the second translation spring 64, cutting off the connection between the second connecting hole 53 and the second inner opening 52, thereby preventing the gas medium in the first inner opening 51 from leaking.

[0058] ⑨ Disassemble the pressure sensor 24; the circular turntable 91 is in the second state driven by the stepper motor; then, the external placement air pump adds gaseous medium to the input pipe 93, and the gaseous medium will be introduced into the spacing cavity 47 after passing through the first connecting hole 48, pushing the second translation follow-up block 43 to move outward, and then pushing the translation slider 41 to disengage from the side locking concave surface 242, and then pull out the pressure sensor.
