When after application of sample completes, needs mix, vibration motor control panel 75 starts vibration motor 78, and vibration motor 78 drives code-disc 76, contiguous block 80, slide bar 83 and connecting rod 85 to move around to make oscillating plate 77 to realize vibration and mixed by the sample after application of sample.
When needs while or when respectively imbibition, liquid feeding being carried out to many sample needles, YZ control panel 30 starts adjustment motor 52, regulate motor 52 when rotating, the sample arm holder 39 made and regulate motor 52 to be threaded moves along Y direction, spacing between itself and another sample arm holder 39 is changed, thus makes different sample needle can stretch into same container simultaneously or stretch into different vessels respectively to draw reagent.
The utility model has stable, light and handy, low cost, portable feature, fills up the vacancy of current small-sized loading device series.Replace manually completing the experimentations such as reagent mixing, liquid quantitative application of sample when can liquid sample or liquid reagent be adopted for the organizational structure that sample size is less to test, realize overall process such as experiment application of sample, reagent mixing etc.
The above is only preferred implementation of the present utility model; for those skilled in the art; under the prerequisite not departing from the utility model principle, can also make some improvement and modification, these improve and modify and also should be considered as this practical new protection domain.
