The invention relates to the technical field of sampling tools, and discloses an ejection type tree branch and leaf sampler which comprises a handle, a guide tube, an ejection mechanism and a trigger, the ejection mechanism is connected to the interior of the guide tube, the handle is connected to the outer side of the guide tube, the trigger is connected between the handle and the guide tube, and the ejection type tree branch and leaf sampler further comprises a cutting assembly which comprises a traction block and a cutting line, the traction block is erected on the ejection mechanism and is locked after moving to the trigger along the guide pipe, the trigger is used for unlocking, the traction block is ejected under the driving of the ejection mechanism, one end of the cutting line is connected to the traction block, the other end of the cutting line is connected to the guide pipe, and the traction block drives the cutting line to be erected on a target branch. According to the ejection type tree branch and leaf sampler provided by the invention, a user can realize sampling through the ejection type tree branch and leaf sampler through the cooperation of the ejection mechanism, the cutting line and the traction block, so that sampling through a rod-shaped structure and a pestle mode in the prior art is avoided, and branch and leaf sampling operation is simpler and more efficient.

The name of the utility model is a disposable fungus sampling suite. Belongs to the technical field of skin surface fungus sampling detection. The fungus sampling film suite mainly solves the problems that a sampling film is easy to deform during sampling in the existing fungus sampling film suite, so that the operation is inconvenient, and the sampling film is adhered to a slide. The device is mainly characterized by comprising a sampling film, a slide, a sampling film reinforcing layer, a glue protection layer and a disposable sampling packaging bag, a gluing layer is arranged on the bottom surface of the sampling film; the sampling membrane reinforcing layer is consistent with the sampling membrane in appearance and is of a hollow structure, and the bottom surface is fixedly connected with the sampling membrane in a bonding manner; the glue protection layer covers the gluing layer; the sampling film reinforcing layer, the sampling film and the glue protection layer form an integrated sampling piece, and the integrated sampling piece and the slide are put into a disposable sampling packaging bag together. The utility model has the characteristics that the sampling film is not soft any more, the sampling operation is easy, and the sampling film is easy to adhere to a slide, and is mainly used for quickly sampling fungi on the skin surface.

The application discloses a layered sampling monitoring device and method for freeze-thaw cycle test, which comprises a freeze-thaw cycle box, a layered soil sample culture unit, an in-situ monitoring unit and a non-destructive sampling unit. The application provides a layered sampling monitoring device and test method for freeze-thaw cycle test, which has a reasonable structure design and is convenient to operate. The device can realize non-destructive or slightly destructive extraction of target soil samples after different freeze-thaw cycles without damaging the continuity of the whole test, and can realize real-time monitoring of the moisture content and temperature changes of the soil samples in the freezing and thawing process, thereby providing accurate and continuous test data for in-depth study of the evolution law of the freeze-thaw cycle on the soil properties. The device and method of the application significantly improve the continuity and accuracy of the data, and provide a powerful tool for revealing the effect of freeze-thaw on the soil erosion mechanism.
