Sampling device for vector biological sample

The utility model discloses a sampling device for a vector organism sample, and particularly relates to the field of vector organisms, the sampling device comprises an outer shell, the inner part of the outer shell is fixedly connected with a limiting mechanism, and the limiting mechanism comprises a limiting pipe, an observation hole, an opening button, a closing button, a circuit board, an electric push rod, a limiting plate and a needle hole. By arranging the limiting mechanism, the position of a vector organism in the limiting pipe can be observed through an observation hole, then a starting button is pressed to enable a conductive module on the lower portion to touch carbon film interdigitals on a circuit board, the carbon film interdigitals are connected, then an electric push rod is controlled to be opened, a limiting plate is pushed to move downwards, and the vector organism is fixed in the limiting pipe; the limiting plate can be retracted by pressing the closing button after blood sampling is comple
