Description

A kind of fast tobacco leaf sampling device

Technical field

This utility model relates to a kind of fast tobacco leaf sampling device, belongs to tobacco planting lab-size equipment.

Background technology

In tobacco planting research field, often the Nicotiana tabacum L. of Nicotiana tabacum L. need to be sampled and carry out gene expression, protein and the research of secondary metabolites assay, existing sampling means is by shears the regional area of Nicotiana tabacum L. to carry out cutting, and Nicotiana tabacum L. cutting got off puts into centrifuge tube or masking foil wrap after place into and liquid nitrogen is taken back laboratory be analyzed；In long-term sampling process, technical staff finds that existing sampling means there is problems in that first, uses shears sample rate the slowest, and its cell can produce series of biochemical reactions after Nicotiana tabacum L. leaves cigarette strain, cause part RNA in Nicotiana tabacum L. to be degraded, the material such as protein and secondary metabolites changes, can not the practical situation of actual response tobacco sample, cause tobacco sample analysis result generation deviation；The second, using shears sample rate very slow, and need both hands jointly to coordinate when shearing, the tobacco leaf thus needing another staff to be responsible for getting off cutting carries out access, exist take a lot of work, time-consuming problem.

Summary of the invention

The technical problems to be solved in the utility model is to provide and a kind of singlehanded can be rapidly completed Nicotiana tabacum L. sampling, the fast tobacco leaf sampling device of simple in construction, can overcome the deficiencies in the prior art.

The technical solution of the utility model is:

Fast tobacco leaf sampling device, it includes jaw arrangement, the bare terminal end of jaw arrangement be connected to can grafting on cut trim ring and lower undertaking circle, connecting in the lower underside accepting circle has access box, upper cut trim ring in be provided with protruding platform.

Above-mentioned fast tobacco leaf sampling device is, the lower external diameter of circle of accepting is less than the internal diameter above cutting trim ring.

Aforesaid fast tobacco leaf sampling device is, the external diameter of protruding platform is less than the lower internal diameter accepting circle.

Compared with the prior art, this utility model the bare terminal end in jaw arrangement be connected to can grafting on cut trim ring and lower undertaking circle, connect in the lower underside accepting circle and have access box, upper cut trim ring in be provided with protruding platform, so utilize singlehanded as used operation as shears just can be rapidly completed the collection of sample Nicotiana tabacum L. regional area, thus improve efficiency, connect in the underside accepting circle has access box just can improve collection efficiency and can avoid again polluting by the Tobacco Leaves access of collection in access box simultaneously.The lower external diameter accepting circle less than above cutting the internal diameter of trim ring, the external diameter of protruding platform less than the lower internal diameter accepting circle, so on cut trim ring and be positioned at and lower accept circle, can be by the blade press-in access box of cutting under the effect of projection platform, it is to avoid blade is stuck in be cut in trim ring.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Detailed description of the invention

Embodiment 1: as shown in Figure 1, the installation theme of this fast tobacco leaf sampling device is jaw arrangement 1, the bare terminal end of jaw arrangement 1 be connected to be mutually inserted on cut trim ring 2 and lower undertaking circle 3, upper cut trim ring 2 in be provided with protruding platform 5, use helicitic texture to connect in the lower lower section accepting circle 3 and have access box 4, preferred version is that the lower external diameter of circle 3 of accepting is less than the internal diameter above cutting trim ring 2, the external diameter of protruding platform 5, less than the lower internal diameter accepting circle 3, so may insure that during shearing the blade of cutting will not be stuck in and cuts trim ring 2 and lower accept in circle 3.It is threaded connection by two sections at the box body of access box 4 and constitutes, so facilitate the taking-up of later stage tobacco sample.

Claims (3)

1. a fast tobacco leaf sampling device, it includes jaw arrangement (1), it is characterized in that: the bare terminal end of jaw arrangement (1) be connected to can grafting on cut trim ring (2) and lower undertaking encloses (3), connect in the lower underside accepting circle (3) and have access box (4), upper cut trim ring (2) in be provided with protruding platform (5).

Fast tobacco leaf sampling device the most according to claim 1, it is characterised in that accept the external diameter of circle (3) under: less than the internal diameter above cutting trim ring (2).
