Easily-settled and layered liquid uniform sampler

The utility model relates to an easy-to-settle layered liquid uniform sampler which comprises a handle, a pressing pull rod, a fixing ring, a knob fixing screw, a fixing shaft, a fixing block, a lifting steel rope, a sampler body, a sealing piece, a spring, a spring fixing piece and a limiting block. The utility model belongs to the technical field of liquid sampling equipment, and particularly provides a uniform sampler for liquid easy to settle and stratify, which adopts a one-way circulation mode to sample and store, realizes opening of a sealing piece by pressing a pull rod and lifting a steel rope, realizes automatic return of the sealing piece by virtue of a spring, and is simple in structure and convenient to operate. The sampler is in a closed state after sampling is completed, the possibility that the sampler is polluted by other settling layer liquid during sampling of easily-settled stratified liquid is effectively avoided, meanwhile, scales are arranged on the outer surface of the sampler body, st
