In the contact process of the shifting block 401 and the V-shaped swinging piece 402, the V-shaped swinging piece 402 can be driven to rotate along the supporting rod 403 along with the rotation of the shifting block 401 until the V-shaped swinging piece 402 rotates to be incapable of continuously contacting with the shifting block 401, and the V-shaped swinging piece 402 is separated from the shifting block 401.
In the initial state, the V-shaped swing piece 402 is located above the corresponding valve block 303, and the swing rod i 4021 of the V-shaped swing piece 402 is in contact with the upper surface of the valve block 303 to generate downward pressure on the valve block 303, and at this time, the spring 306 located outside the guide rod between the valve block 303 and the motor mounting disc 201 is in a compressed state, and a compression force is generated in the spring 306.

When the driving motor 205 is started, the dial 401 mounted on the output shaft rotates along with the rotation of the output shaft of the driving motor. The shifting block 401 will contact with the V-shaped swing piece 402 above each valve block in turn during the rotation process.

After the device is retracted to the deck, the specimen sample is collected and processed for analysis.
