when one test tube needs to be taken, the worker fixes the test tube fixing frame 16 by one hand and holds the test tube by the other hand, the lower end of the test tube is lifted upwards by the worker, the test tube is extruded from the two lug type fixing seats 22, the test tube is moved to the outside of the U-shaped groove 17 by the worker, so that the test tube is taken down from the test tube fixing frame 16, meanwhile, the bottom of the test tube can be pushed manually by the worker, the test tube is lifted upwards slowly, the upper end of the test tube is held again to draw out the test tube, and the test tube can be taken down;

when a test tube on one of the test tube fixing frames 16 needs to be taken, the worker reversely rotates the annular butt joint fixing seat 35 to separate the annular butt joint fixing seat 35 from the thread butt joint groove 15, the worker manually pulls the test tube fixing frame 16 to draw the splicing cylinder 33 out of the butt joint groove 12, so that the whole test tube fixing frame 16 is taken down, and the worker can perform other operations on the test tube;

when a large number of test tubes or all test tubes need to be taken, the worker takes off the first test tube fixing frame 16 according to the operation, the removed test tube holder 16 is now temporarily placed in the containing recess 40 in the containing block 38, the test tube holder 16 is fixed in the holding groove 40 by the magnetic property of the bar magnet 41, and at this time, the worker takes down another test tube holder 16, and after taking down, the splicing cylinder 33 on the other test tube fixing frame 16 is inserted into one of the butt-joint grooves 12 on the splicing fixing seat 27, meanwhile, the square butt joint block 37 is inserted into the square limiting butt joint groove 14 and is connected with the thread butt joint groove 15 through the thread of the annular butt joint fixed seat 35, so that the two test tube fixing frames 16 form a whole, and at the moment, the test tube fixing frames 16 are taken down one by one according to the operation and spliced;

in the splicing process of the test tube fixing frame 16, the size of the containing groove 40 is observed, when the spliced size of the test tube fixing frame 16 is the same as that of the containing groove 40, other test tube fixing frames 16 are spliced according to the size of the containing groove 40, and when all the test tube fixing frames are spliced and placed in the containing groove 40, a worker can manually take up the containing frame 38, so that the test tube can be moved to a position needing to be used;

in the splicing process of the test tube fixing frame 16, because the positions of the splicing fixing seats 27 are all the same, the splicing fixing seats 27 need to be adjusted during splicing so that the test tube fixing frame 16 can be spliced into a whole, when the splicing fixing seats 27 need to be adjusted, a worker can manually push the splicing baffle 30 to enable the splicing fixing seats 27 to start moving, when the splicing fixing seats 27 move, the limiting sliding balls 26 are extruded to move from the limiting sliding ball grooves 29 to the limiting sliding grooves 28 and move to the other limiting sliding ball grooves 29 along with the movement of the splicing fixing seats 27, at the moment, the splicing baffle 30 at the other end of the splicing fixing seats 27 is in contact with the test tube fixing frame 16, meanwhile, the first square annular magnets 31 and the second square annular magnets 32 are in contact and generate attraction force, and the splicing fixing seats 27 are fixed through the attraction of magnetic force and the limitation of the limiting sliding balls 26, at this time, the splicing fixing seat 27 is adjusted, and the worker can assemble the test tube fixing frame 16;

after the staff used whole device that finishes, this moment the staff alright through manual take off all test tubes from test tube mount 16 one by one to take off test tube mount 16 from test tube mount seat 11, splice test tube mount 16 according to the size that holds recess 40 again, after the concatenation finishes, place the test tube mount 16 after the concatenation and hold in the recess 40, so that use next time.

In this device, when need use a plurality of mount pads 3 to fix the test tube simultaneously, the staff can install the splash guard 43 in the top of mount pad 3 this moment, avoids leading to during liquid splashes and enters into other test tubes because of misoperation, influences the going on of medical experiment.
