[0030] The plug-in mechanism 4 includes a fixed groove 41, which is fixedly connected to the outside of the pH meter 1. A fixed cylinder 42 is fixedly connected to one side of the fixed groove 41. A spring 43 is fixedly connected to the inner wall of the fixed cylinder 42. A circular plate 45 is fixedly connected to one end of the spring 43. A long rod 44 is sleeved on the inner ring of the spring 43. An insertion shaft 49 is fixedly connected to one side of the circular plate 45. A long plate 48 is fixedly connected to the end of the long rod 44 away from the circular plate 45. A dislocation block 46 is fixedly connected to the outer wall of the long rod 44. The long plate 48 is fixedly connected to the front end of the long rod 44. A fixed plate 47 is fixedly connected to the outside of the pH meter 1, and a movable block 401 is fixedly connected to the outside of the sheath 2.

[0031] Furthermore, the movable block 401 is movably connected to the inner wall of the fixing groove 41 , and the insertion shaft 49 penetrates the front side of the fixing groove 41 and moves, which can serve the purpose of initially limiting the position of the sheath 2 .

[0032] Furthermore, a dislocation opening is provided inside the fixing plate 47 , and the size of the dislocation block 46 is smaller than the size of the dislocation opening, so that the dislocation block 46 can be moved through the dislocation opening.

[0033] Furthermore, a through hole is formed on a side of the fixing tube 42 away from the fixing groove 41 , and the long rod 44 passes through the through hole, so that the long rod 44 can move through the through hole.

[0034] Furthermore, the circular plate 45 is slidably connected to the inner wall of the fixed tube 42 , and the long rod 44 is fixedly connected to one side of the circular plate 45 , so that the circular plate 45 can move stably to compress the spring 43 .

[0035] Furthermore, a locking hole is provided on one side of the movable block 401 , and the insertion shaft 49 is inserted into the inner wall of the opening of the locking hole, so that the insertion shaft 49 and the locking hole cooperate to stably limit the movable block 401 .

[0036] Embodiment 2

[0037] See also Figures 1 to 6 On the basis of the first embodiment, the sealing mechanism 5 further comprises a connecting sleeve 51, the connecting sleeve 51 is fixedly connected to the outer wall of the tube sleeve 3, the inner wall of the connecting sleeve 51 is threadedly connected with a sealing sleeve 52, and the outer wall of the sealing sleeve 52 is fixedly connected with a torsion sleeve 53, so as to further improve the stability of the seal.

When the dislocation block 46 completely penetrates the fixed plate 47, the rotating dislocation block 46 is rotated to dislocate the dislocation block 46 and the fixed plate 47, and the dislocation block 46 is limited so that the plug shaft 49 cannot move easily. Then the sheath 2 is inserted to the outside of the pH meter 1, and the movable block 401 can be inserted into the inside of the fixed groove 41 to achieve the purpose of preliminary support and limitation, and then the dislocation block 46 is rotated again. The positioning block 46 allows the dislocation block 46 to be moved through the fixed plate 47. At this time, the spring 43 in the compressed state will push the circular plate 45 to drive the plug shaft 49 to be inserted into the interior of the movable block 401, and limit the movable block 401, so that the movable block 401 cannot be easily moved, thereby realizing the installation of the sheath 2, which can protect the pH meter 1 and protect the electrode part of the pH meter 1 from being contaminated and damaged by the sample, ensuring stable signal transmission, and improving the service life and accuracy of the pH meter 1. At the same time, it is also convenient for disassembly and assembly operations, and convenient for staff to perform calibration and maintenance operations, thereby achieving good operating efficiency.
