| Zusammenfassung: | According to the sampling detection pen provided by the utility model, in the working process of the sampling detection pen, when sampling is needed, the sealing cylinder connector is detached, the driving cylinder is driven to rotate through the rotating head, and the sampling swab is driven to rotate through the sliding column and the bearing block in the rotating process of the driving cylinder. In the process, the sliding column moves along the threaded groove so as to drive the sampling swab to move downwards through the bearing block, so that the sampling head part of the sampling swab is moved out of the containing cylinder for a user to use. After the sampling is finished, the driving cylinder is driven to rotate in the opposite direction through the rotating head, and the sampling swab is driven to rotate in the opposite direction through the sliding column and the bearing block in the rotating process of the driving cylinder. In the process, the sliding column moves reversely along the threaded groo |
