[0002] A nucleic acid extractor is an instrument that uses matching nucleic acid extraction reagents to automatically extract nucleic acid from samples. Nucleic acid extractors are divided into two categories: one is a large-scale automated instrument, generally called an automatic liquid workstation; the other is a small-scale automated nucleic acid extractor, which uses packaged matching reagents to automatically complete the extraction and purification process. Large-scale automated liquid workstations are rarely used because of their high equipment and operating costs and are only suitable for extracting thousands of the same type of specimens at a time. Small-scale automated instruments are increasingly used because of their low equipment and operating costs and easy operation.

[0003] The existing fully automatic nucleic acid extraction instrument has poor overall flexibility and is generally placed on a table for use. It is inconvenient to move the entire instrument, which increases the difficulty of overall transportation and thus reduces overall practicality. Utility Model Content

[0030] Specifically, two insertion holes 206 are symmetrically provided on the top of the outer frame 201, and the two insertion rods 208 are respectively inserted into the two insertion holes 206. Two through holes 205 are symmetrically provided on the top of the outer frame 201, and the inner diameters of the two through holes 205 are equal to or greater than the inner diameters of the two insertion holes 206.

[0031] In the initial state, the two insertion rods 208 are respectively inserted into the two insertion holes 206, each spring 1 2010 is in a compressed state, and the bottom surface height of each rubber pad 2014 is greater than the bottom end surface height of each universal wheel 3. At this time, the main unit 1 can be moved by each universal wheel 3 to realize the overall transportation of the nucleic acid extraction instrument;

[0032] When the nucleic acid extractor needs to be used, first pull the two rubber sleeves 2017 upwards to make the two rods 208 rise until they are removed from the two sockets 206 respectively. At the same time, each spring 1 2010 is compressed again, and then the two top blocks 207 are rotated to make the two rods 208 pass through the two through holes 205 respectively. Then, the two top blocks 207 are released. At this time, each spring 1 2010 is reset to drive the two lifting plates 202 to slide downward along the two U-shaped round rods 2012 respectively, and drive each rubber pad 2014 to descend through each support column 2011 until it is tightly fitted with the table surface, thereby supporting and fixing the host 1, and finally the nucleic acid extractor is used.
