[0023] See also Figure 3 and Figure 4 The support assembly includes several connecting bars 10, one side of which is fixedly connected to the top of the circular plate 9, and the other side of which is movably mounted with support blocks 13. The top and bottom of the support blocks 13 are both flat. The support blocks 13, connecting bars 10 and other components are used to form a bracket, so that the adjustable precision pipette body 1 can be stably placed in a vertical state inside the disinfection cabinet to improve the disinfection effect.

[0024] See also Figure 2 、 Figure 3 and Figure 4The connecting assembly includes several round rods 14, the tops of several round rods 14 are fixedly connected to the bottom of the circular ring plate 9, and the outer sides of several round rods 14 are movably mounted with round sleeves 15, and the bottom of the round sleeve 15 is rotatably connected with a threaded block 16. Several threaded holes 7 are opened on the top of the adjustable precision pipette body 1. The connection between the circular ring plate 9 and the top of the adjustable precision pipette body 1 is achieved by threading the threaded blocks 16 into the threaded holes 7, thereby improving the stability of the installation of components such as the circular ring plate 9 and the top of the adjustable precision pipette body 1.

[0025] See also Figure 3 and Figure 4 The connecting bar 10 is fixedly connected to the side of the circular ring plate 9 with a screw rod 11, and the outer side of the screw rod 11 is threadedly connected to a threaded sleeve 12, and the threaded sleeve 12 is fixedly connected to the side wall of the corresponding support block 13. Through this setting, the spacing between multiple support blocks 13 can be adjusted, the contact area can be increased, and the support stability can be improved.

[0026] See also Figure 4 A spring 17 is fixedly connected between the bottom end of the round rod 14 and the bottom of the inner wall of the round sleeve 15.

After the adjustment is completed, the adjustable precision pipette body 1 is used as a whole to complete the subsequent liquid extraction work. After use, when it needs to be disinfected, the removed sleeve 8 can be inserted into the storage groove 5, and multiple threaded blocks 16 are pulled downward in sequence, so that the threaded blocks 16 drive the round sleeve 15 to move downward, and the round sleeve 15 cooperates with the round rod 14 to stretch the spring 17. Then, the threaded blocks 16 are threadedly connected to the corresponding threaded holes 7. After all the threaded blocks 16 are threadedly connected to the threaded holes 7, the connection between the annular plate 9 and the top of the adjustable precision pipette body 1 is realized. Then, the threaded connection between the screw 11 and the threaded sleeve 12 is used to adjust the distance between the support block 13 and the corresponding connecting strip 10, increase the spacing between multiple support blocks 13, and subsequently use multiple groups of support blocks 13 to vertically support the adjustable precision pipette body 1, thereby improving stability and further improving the subsequent disinfection effect.
