Novel liquid sampling device

The invention discloses a novel liquid sampling device. The technical key points of the device are that the device comprises a base body, a sampling cavity groove, a sample separation cavity, a samplemixing cavity and a sampling head. The sampling cavity grooves, the sample separation cavities and the sampling heads are arranged in one-to-one correspondence. The number of the sample mixing cavityis one. The number of the sampling cavity grooves is at least two and the sampling cavity grooves are sequentially formed in the lower surface of the base body. The sample separation cavity and the sample mixing cavity are arranged in the base body. A first extraction pipe is connected between the sample separation cavity and the sampling cavity groove. A second extraction pipe is connected between the sample mixing cavity and the sample separating cavity, the sampling head is arranged in the sampling cavity groove in a sliding manner, a telescopic corrugated pipe is arranged between the sampling head and the first ex
