The joint 200 further comprises a second connecting part 20 comprising a fixed part 30 and a sliding part 40. The top side of the fixed part 30 is provided with a groove 31, and the outer side is integrally provided with a first annular boss 32. The groove 31 is in sliding connection with the outer side of the first connecting part 10. The inner side of the sliding part 40 is integrally provided with a second annular boss 41. The second annular boss 41 is arranged on the top side of the first annular boss 32, and a first spring 42 is arranged between the first annular boss 32 and the second annular boss 41. A plurality of circular arc-shaped through holes 33 are uniformly arranged on the circumferential side of the fixed part 30. Any circular arc-shaped through hole 33 is arranged on the inner side of the second annular boss 41. A clamping bead 34 is arranged in the circular arc-shaped through hole 33. When the sliding part 40 slides and presses the first spring 42 and the first connecting part 10 slides to the bottom side of the groove 31, the clamping bead 34 is clamped into the annular clamping groove 11.

[0027] When working, the mobile sliding part 40 is moved to make the fixed part 30 and the sliding part 40 slide relative to each other, then the first connecting part 10 is clamped into the second connecting part 20, at this time, the first connecting part 10 slides into the groove 31 of the fixed part 30, the clamping ball 34 is pushed out of the arc-shaped through hole 33, the first connecting part 10 is continuously slid into the bottom side of the groove 31, the sliding part 40 is loosened, and the sliding part 40 returns to the initial position under the action of the first spring 42, at this time, the clamping ball 34 is clamped into the annular clamping groove 11. Through the matching connection of the plurality of uniformly arranged clamping balls 34 and the annular clamping groove 11, the connecting pipe 101 and the probe 102 can be quickly and firmly connected and fixed, and the device is not easy to loosen, has high sensitivity, and is convenient for daily storage and carrying.

[0028] The second annular boss 41 and the third annular boss 43 form an accommodation cavity 44, which is used to push the clamping ball 34 into the accommodation cavity 44 when the groove 31 and the first connecting part 10 slide into contact with the clamping ball 34. Moreover, the clamping ball 34 does not completely enter the accommodation cavity 44, but only enters a part of the accommodation cavity 44.

[0029] The inner circular area of the arc-shaped through hole 33 is smaller than the cross-sectional area of the clamping ball 34, and the outer circular area of the arc-shaped through hole 33 is larger than the cross-sectional area of the clamping ball 34. This design is to avoid the clamping ball 34 from entering the groove 31, and at the same time, to make the clamping ball 34 enter the accommodation cavity 44.

[0030] The clamping balls 34 are distributed on the circumferential side of the fixed part 30, for example, eight clamping balls 34 can be uniformly distributed on the circumferential side of the fixed part 30. Embodiment

[0034] By setting the second spring 13 and the arc-shaped baffle 12, in order to separate the first connecting part 10 and the second connecting part 20, the sliding part 40 is slid, at this time, the second spring 13 provides a elastic force to the arc-shaped baffle 12, and then to the clamping bead 34, so that the clamping bead 34 is separated from the circular arc-shaped through hole 33, and the clamping bead 34 is prevented from being clamped by the circular arc-shaped through hole 33. Embodiment
