Furthermore, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted", "provided", "sleeved/connected", "connected", and the like are to be understood in a broad sense, such as "connected", which may be fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Example (b):

please refer to fig. 1-2 and include test tube body 1 and fixing device, fixing device is located test tube body 1, be provided with scale 2 on test tube body 1, scale 2 is located the screw thread 4 downside, can make things convenient for the sampling personnel to know the numerical quantity of sample clearly through setting up scale 2, more accurate sample, be provided with lid 3 on test tube body 1, be provided with the sealing washer on the lid 3, through setting up lid 3 that has the sealing washer, can prevent to a certain extent that the sample from spilling over from the test tube, thereby guarantee the accuracy nature of sample content's accuracy nature assurance experiment.

Fixing device is including solid fixed ring 5, mounting groove 6, compression spring 7, compact heap 8 and dog 9, gu fixed ring 5 is controlled both ends and has all been dug mounting groove 6, be connected through compression spring 7 between compact heap 8 and the mounting groove 6, dog 9 sets up and keeps away from compression spring 7 one side upper end at compact heap 8, be carved with screw thread 4 on the test tube body 1, gu fixed ring 5 passes through screw thread 4 and test tube body 1 threaded connection, make solid fixed ring 5 can be more stable fix on test tube body 1 through threaded connection, the cover is equipped with anti-skidding cover on dog 9, anti-skidding cover surface is carved with anti-skidding line, through setting up the anti-skidding cover that can anti-skidding line, can reduce the possibility that experimental personnel appear skidding when pressing dog 9 with the hand to a certain extent.

When the test tube needs to be placed on the test tube rack after sampling is completed, an experimenter firstly rotates the fixing ring 5 to a proper position along the spiral thread 4, then presses the stop blocks 9 on two sides with hands, puts the test tube on the test tube rack and then presses the stop blocks 9 inwards with force until the pressing block 8 enters the test tube rack and releases the hands, so that the stop blocks 9 fall on the test tube rack, the compression spring 7 is in a compression state at the moment, so that the pressing block 8 is tightly attached to the inner wall of the test tube rack and is not easy to slide, the test tube can be fixed on the test tube rack due to the small length of the test tube and the length of the test tube rack because the stop blocks 9 exist, if the length of the test tube is larger than the length of the test tube rack, the test tube can be placed on the test tube rack by adjusting the position of the fixing ring 5, thereby not only realizing that the test, the safety of the sample is ensured to a certain extent.
