A lifting lug 6 is provided at the middle position of the top end of the top plate 5. Thus, it is convenient for technicians to lift the cylinder body 1 containing the metal lithium sample out of the water through the lifting lug 6 floating to the water surface after the experiment, without the need for technicians to reach into the water to take samples, which is convenient for technicians to take and place metal lithium samples and has stronger operability;

[0022] During use, the mounting sleeve groove 4 with the airbag 3 nested inside is fixedly connected to the top plate 5 through the connecting rod 8. The airbag 3 can drive the top plate 5 and the lifting lug 6 provided on its top to float to the water surface, so as to facilitate technicians to lift the cylinder body 1 containing the lithium metal sample out of the water through the lifting lug 6 floating to the water surface after the experiment, without the need for technicians to reach into the water to take samples;

[0023] As a further implementation manner of this embodiment, as Figure 1 , Figure 3 and Figure 4 shown, an adjusting assembly is provided between the bottom end of the top plate 5 and the top end of the cover body 2.

By rotating the adjusting screw sleeve 10, the purpose of driving and adjusting the lifting of the suspension wire 13 can be achieved, thereby adjusting the combined height of the suspension wire 13 and the connecting pipe 7, and thus adjusting the distance between the top plate 5 and the cylinder body 1, so as to adaptively adjust the depth at which the cylinder body 1 containing lithium metal is put into and sinks into the water according to the experimental requirements, and ensure the stability of the cylinder body 1 in the water;

[0024] During use, by rotating the adjusting screw sleeve 10, the lifting of the suspension wire 13 can be driven and adjusted, thereby adjusting the combined height of the suspension wire 13 and the connecting pipe 7, and thus adjusting the distance between the top plate 5 and the cylinder body 1, so as to adaptively adjust the depth at which the cylinder body 1 containing lithium metal is put into and sinks into the water according to the experimental requirements;

[0025] Specific working principle:

[0026] When using the sample container, first unscrew the cover body 2 and place the lithium metal inside the cylinder body 1, then screw on the cover body 2. Subsequently, according to the experimental requirements, rotate the adjusting screw sleeve 10 to drive and adjust the lifting of the suspension wire 13, thereby adjusting the combined height of the suspension wire 13 and the connecting pipe 7, and thus adjusting the distance between the top plate 5 and the cylinder body 1. Then, the depth at which the cylinder body 1 containing lithium metal is put into and sinks into the water can be adaptively adjusted according to the experimental requirements. Subsequently, the cylinder body 1 containing lithium metal is placed into the experimental water body, and the airbag 3 can drive the top plate 5 and the lifting lug 6 provided on its top to float to the water surface. During the laboratory test for detecting the nitrogen content of lithium metal, the lithium metal is in full contact with water through the through groove 11 while preventing the lithium metal from falling into the water. After the experiment, technicians lift the cylinder body 1 containing the lithium metal sample out of the water through the lifting lug 6 floating to the water surface, without the need for technicians to reach into the water to take samples.
