Description
Technical field
The utility model relates to Bioexperiment equipment technical field, is specifically related to a kind of aquatic livestock fast sampling tweezer pincers.
Background technology
Since the mid-eighteenth century, the mankind never to stop paces to the exploration of organic sphere tera incognita, constantly bring forth new ideas and exploitation in biological research activities, develop various instrument and instrument comes to be biological experimental service better.Wherein, " sampling " is the most basic in biological experiment and a requisite step, for different experimental subjectss, also the varying of suitable sampling instrument: as hair, musculature etc. utilize the General experimental such as surgical scissors or lancet instrument, the sampling of blood then utilizes syringe.
But under special circumstances, need design more rationally, more professional instrument goes to sample fast and efficiently.In aquatic products field, gather the sampling point of biological tissue from live fish health and be generally fin, can minimize to the injury of fish like this, sampling tool is then traditional surgical scissors, if from egg-shaped pompano (
trachinotus ovatus), cobio (
rachycentron canadum), grouper, jewfish (
lateolabrax japonicus), the bodily form such as schizothoracin is comparatively large or after leaving water body, vigor is stronger fish health samples, certain drawback can be there is: (1) adopt surgical scissors to carry out fin sampling is minimum needs to cut two cuttves and just can complete, sample rate is slow, and live fish dried up after can struggle with all one's might, sampling personnel easily stabbed by fin ray, the fish fin ray even had is poisonous, constitutes certain risk to sample collector; (2) due to live fish struggle, in sampling process, sample is easily got rid of and is landed, cause sample contaminated or lose; (3) for the sampling of large-scale parent population, general caryophyllus oil is anaesthetized fish, postanesthetic fish vigor declines, ensure that sample collector does not stab by fin spine to a certain extent, but the more difficult assurance of adding proportion, if the amount of adding caryophyllus oil is excessive, fish will be anaesthetized till death, cause larger economic loss, anesthetic action is not obvious at least excessively, easily stabs staff.
Therefore, adopt traditional surgical scissors to carry out the sample collection of live fish fin, can there is certain risk, and convenience is poor, efficiency is low.
Summary of the invention

The purpose of this utility model is achieved through the following technical solutions: a kind of aquatic livestock fast sampling tweezer pincers, comprise tweezer pincers body, tweezer pincers body comprises the fixed arm and lever arm that can relatively fold, one end of fixed arm, lever arm is flexibly connected, the spaced formation free end of the other end of fixed arm, lever arm, the outer of the free end of lever arm is convexly equipped with the blade for cutting off sample downwards, the position of the outer opposing blades of the free end of fixed arm is convex is provided with blade pad, is provided with the load sample groove for holding sample in blade pad.
Further, described load sample groove is pentagon.
Further, described blade is connected in sequence by four blade units.
Further, described blade pad is connected in sequence by four blade single pad bodies, and one end of described blade pad is fixed with block, and block and four blade single pad bodies surround described load sample groove.
Further, the top of described fixed arm one end is fixed with contiguous block, and one end of described lever arm is movably connected on contiguous block.
Further, the bottom of the described fixed arm other end and the top of the described lever arm other end are respectively arranged with anti-slip veins.
Further, the thickness of described fixed arm, lever arm is 0.8-1.2mm, and the length of described fixed arm, lever arm is 80-95mm.
Further, the height of described blade, described blade pad is 0.8-1.2mm.
Further, the width of described fixed arm, lever arm first increases gradually from one end of fixed arm, lever arm to the other end respectively and forms increase portion, then reduces gradually to form tip.
Further, described increase portion is 12-14.5:1 with the length ratio of described tip, and the angle of tip is 70-90 °.
The beneficial effects of the utility model are: when the utility model uses, hold tweezer pincers body, firmly press lever arm, the free end of lever arm and the free end of fixed arm are mediated, sample just can be got off by sharp blade cuts, and drop in load sample groove, then with the use of tip tweezers, sample is taken out from load sample groove; If the sample size of getting once is inadequate, can again get several times to reach enough amounts more.
The utility model structure is simple, and material price is lower, small and exquisite portable, operates quick and convenient, is applicable to outdoor and indoor sample; Tissue sample can be gathered from live fish fin quickly and safely, also may be used for the collection of the mantle tissue sample as shellfishes such as black lip shells; And because its operation has ensured rapidly the personal safety of operating personnel, reduce risk, also assures that simultaneously sample not easily drop lose or contaminated.

Embodiment
For the ease of the understanding of those skilled in the art, be further described the utility model below in conjunction with embodiment and accompanying drawing 1-2, the content that embodiment is mentioned is not to restriction of the present utility model.
See Fig. 1-2, a kind of aquatic livestock fast sampling tweezer pincers, comprise tweezer pincers body, tweezer pincers body comprises the fixed arm 1 and lever arm 2 that can relatively fold, one end of fixed arm 1, lever arm 2 is flexibly connected, the spaced formation free end of the other end of fixed arm 1, lever arm 2, the outer of the free end of lever arm 2 is convexly equipped with the blade 21 for cutting off sample downwards, the position of the outer opposing blades 21 of the free end of fixed arm 1 is convex is provided with blade pad 11, is provided with the load sample groove 12 for holding sample in blade pad 11.
When the utility model uses, hold tweezer pincers body, firmly pressing lever arm 2, the free end of the free end of lever arm 2 and fixed arm 1 is mediated, sample just can be cut down by sharp blade 21, and drop in load sample groove 12, then with the use of tip tweezers, sample is taken out from load sample groove 12; If the sample size of getting once is inadequate, can again get several times to reach enough amounts more.
The utility model structure is simple, and material price is lower, small and exquisite portable, operates quick and convenient, is applicable to outdoor and indoor sample; Tissue sample can be gathered from live fish fin quickly and safely, also may be used for the collection of the mantle tissue sample as shellfishes such as black lip shells; And because its operation has ensured rapidly the personal safety of operating personnel, reduce risk, also assures that simultaneously sample not easily drop lose or contaminated.
In the present embodiment, described load sample groove 12 is in pentagon.Because load sample groove 12 is in pentagon, the sample of cutting is also in pentagon, and facilitate follow-up experimental implementation, the setting of load sample groove 12 makes sample not easily drop, and ensures that sample is not contaminated or lose.
In the present embodiment, described blade 21 is connected in sequence by four blade units 211.Blade 21 is sharp, hard, is not easy rust, has good cutting performance.
In the present embodiment, described blade pad 11 is connected in sequence by four blade single pad bodies 111, and one end of described blade pad 11 is fixed with block 112, and block 112 and four blade single pad bodies 111 surround described load sample groove 12.The blade pad 11 of fixed arm 1 aligns with the blade 21 of lever arm 2, is to close seamless completely when blade 21 closes with blade pad 11, ensures sample cutting completely.
In the present embodiment, the top of described fixed arm 1 one end is fixed with contiguous block 22, and one end of described lever arm 2 is movably connected on contiguous block 22.The setting of contiguous block 22 is used for being connected and fixed arm 1 and lever arm 2.
