Microscopic recognition molecular liquid collector

The utility model belongs to the field of sample collection, and particularly relates to a microscopic recognition molecular liquid collector, which solves the problems in the prior art that the disassembly and assembly are not fast and the sealing performance is poor, and comprises a sample collection tube and a sampling shell, two symmetrically-arranged pressing plates, two symmetrically-arranged transverse rods and two symmetrically-arranged limiting blocks are slidably assembled in the sample collecting pipe, vertical rods and limiting rods are fixedly connected to the tops of the transverse rods through screws, the tops of the vertical rods are fixedly connected to the bottoms of the pressing plates through screws, and the limiting blocks are fixedly connected to the bottoms of the limiting rods through screws. Through the arrangement of structures such as the mounting blocks and the limiting blocks, during mounting, the two mounting blocks at the bottom of the sampling shell are aligned to mounting groo
