A nematode picking device

Abstract

This utility model discloses a nematode picking device, comprising a shell with a cylindrical groove on its top surface. A movable plate is slidably connected inside the cylindrical groove, and a picking needle is installed in the center of the top surface of the movable plate. A connecting rod is installed at the top of the cylindrical groove, and a cleaning block is fixedly connected to the center of the connecting rod. The cleaning block is slidably connected to the picking needle. A cover is provided on the top of the shell, and a rotating disk is rotatably mounted in the center of the cover. A circular hole is formed through the center of the rotating disk, and openings are formed on both sides of the outer periphery of the cover. Baffles are slidably connected inside the openings. In this utility model, the cooperation of the cover, rotating disk, and baffles with the components allows the picking needle to be placed in the cylindrical groove, preventing the picking needle from sticking to dust and impurities, effectively preventing the picking needle tip from bending or breaking. Furthermore, while the picking needle is being moved, the cleaning block can clean its surface, achieving real-time cleaning of the cleaning block and preventing residue from sticking to it, thus ensuring the quality of the experimental samples.
