Automatic sampler tool hand

The utility model relates to a sampler constructs, especially an automatic sampler tool hand. This manipulator includes a bottom plate, the bottom plate on be equipped with the test tube tray, test tube tray top be equipped with a straw seat, install the reagent straw in the straw seat, the straw seat install on the Z axle translation mechanism of a drive straw seat vertical lift motion, Z axle translation mechanism install on a drive Z axle translation mechanism horizontal slip's X axle translation mechanism, X axle translation mechanism install on a drive X axle translation mechanism horizontal slip's Y axle translation mechanism. The utility model discloses an automatic sampler tool hand passes through the horizontal position and the vertical motion of XYZ axle translation mechanism control straw, realizes operating with the location and the sample circuit notes liquid of test tube, has realized experimental automation with wasing the operation and has gone on to reduce work load, improve the precision of analysis.
