Accurate sampling device for checking authenticity of donkey hide

Abstract

The invention provides an accurate sampling device for checking authenticity of donkey hide, and mainly relates to the technical field of sampling devices. The accurate sampling device comprises a base, supporting legs are arranged at the four corners of the bottom face of the base, an L-shaped supporting frame is fixedly installed on the rear portion of the top face, and an operation table located below the supporting frame is further fixedly installed on the top face. A flattening positioning assembly and an electric telescopic rod are fixedly installed on the top of the inner side of the supporting frame, a movable rod of the electric telescopic rod penetrates through the center of the flattening positioning assembly, and a sampling cutter is detachably installed at the lower end and located between the operation table and the flattening positioning assembly. The flattening and positioning assembly firstly presses the donkey hide, then the pressing plate synchronously moves outwards in the extension direction of the diagonal lines of the square, flattening and positioning of the donkey hide are achieved, the sampling cutter can be replaced according to needs, the sample returning assembly is arranged, sampling can be rapidly and accurately completed, sample completeness is guaranteed, the accuracy and efficiency of donkey hide authenticity inspection are improved, operation is convenient, and practicability is high.
