[0037] Example 2

[0038] Based on Example 1, the difference lies in that a scale line 15 is provided on the outer wall of the injection tube 9, and the scale line 15 is provided along the height direction of the injection tube 9. A magnifying glass 12 is fixedly installed on one side of the support seat 6, and the magnifying glass 12 faces the scale line 15. The scale of the reagent drawn by the injection tube 9 can be observed through the magnifying glass 12 and the scale line 15 to ensure the accuracy of the result.

[0039] Principle and process of the utility model: When using the sampler for sampling, first place the test tube 5 between the two fixing blocks 43 in the fixing seat 3, use the elastic force of the fixing spring 45 to make the sponge pad 44 tightly abut against the outer wall of the test tube 5, so that the test tube 5 is fixed between the two fixing blocks 43, then pull the clamping base 75 downward, place the injection tube 9 between the clamping base 75 and the clamping top seat 73, and let the suction head 11 pass through the through hole 76, and let the rod body of the piston rod 10 pass through the clamping base 75. The notches on the top seat 73 and the push-pull frame 82 are opened, and the truncated cone-shaped end of the piston rod 10 is abutted against the top of the push-pull frame 82, and then the clamping base 75 is released, and the movable seat 74 and the clamping base 75 are driven to rise by the tension of the clamping spring 77, and the injection tube 9 is tightly fixed between the clamping top seat 73 and the clamping base 75. By setting the fixing mechanism 4, test tubes 5 of different diameters can be fixed, and by setting the clamping mechanism 7, injection tubes 9 of different specifications can be clamped.

[0040] After the test tube 5 and the injection tube 9 are installed, the electric lifting rod 2 is turned on by pressing the button 14, so that the output end of the electric lifting rod 2 drives the fixing seat 3 and the test tube 5 to rise, so that the suction head 11 is inserted into the reagent in the test tube 5, and then the electric lifting rod 2 is closed, and the electric telescopic column 81 is started by pressing the button 14. The output end of the electric telescopic column 81 drives the push-pull frame 82 to rise, and the push-pull frame 82 drives the piston rod 10 to rise through the truncated cone-shaped end of the piston rod 10. During the rising process of the piston rod 10, the reagent in the test tube 5 is drawn into the injection tube 9 through the suction head 11. After the reagent extracted from the injection tube 9 reaches the required value, the electric telescopic column 81 is closed.

[0041] The controller 13 can also input the designated scale of the output end of the electric telescopic column 81 through the button 14. After the electric telescopic column 81 is turned on, it will automatically stop when its output end rises to the designated scale. At this time, the reagent of the designated scale required is extracted from the syringe 9. After the sampling is completed, the electric lifting rod 2 is started again, and the output end of the electric lifting rod 2 drops and drives the fixed seat 3 and the test tube 5 to reset. If it is necessary to transfer the reagent in the syringe 9 to other containers immediately, the container is placed under the suction head 11, and then the electric telescopic column 81 is started. The output end of the electric telescopic column 81 drives the push-pull frame 82 to drop and reset. During the descent of the push-pull frame 82, the piston rod 10 is pushed downward by the stop rod 83. The piston rod 10 pushes the reagent in the syringe 9 out, and the reagent flows into the container through the suction head 11. If it is not necessary to transfer the reagent in the syringe 9 immediately, the syringe 9 is directly removed and the electric telescopic column 81 is lowered and reset. By setting the sampling mechanism 8, the reagent in the test tube 5 can be automatically sampled, and the sampling process is fast and accurate.
