[0022] During use, through the cooperation of the telescopic rod 6 and the first limiting ring 7 and the second limiting ring 8, the sampling tube 1 can be folded and stored when it is placed or transported, which effectively reduces the volume of the sampling tube 1 and makes it easier to put it into a backpack, tool box or other transportation equipment, which is convenient for moving and carrying at the oil field site, thereby improving work efficiency. At the same time, folding and storage can reduce collisions and damages during transportation and storage of the sampling tube 1, and protect the integrity and service life of the sampling tube 1.

[0023] like Figure 1-Figure 4 As shown, two positioning holes 10 are provided at the top of the connecting ring 4, bolts 11 are slidably provided on the inner wall of the positioning holes 10, two thread grooves 12 are provided on the surface of the base 2, the thread grooves 12 correspond to the positioning holes 10, the bolts 11 are threadedly connected to the thread grooves 12, threads are provided on the inner wall of the connecting ring 4, a fixing cover 13 is threadedly connected to the inner wall of the connecting ring 4, a sealing ring 14 is fixed to the bottom end of the fixing cover 13, and the sealing ring 14 is in contact with the top of the connecting ring 4.

[0024] In use, the bolt 11 cooperates with the threaded groove 12 to limit and fix the sampling tube 1 when it is stored and transported, preventing the sampling tube 1 from accidentally unfolding when stored, thereby improving the stability of the sampling tube 1. The sealing ring 14 can increase the sealing between the fixed cover 13 and the connecting ring 4, preventing the leakage of the liquid inside the sampling tube 1 during transportation, and at the same time, preventing dust in the air from entering the sampling tube 1 and contaminating the sample, thereby improving the accuracy of the sample data.
