[0010] Preferably, the end of the driving rod away from the fixing ring is spherical.

[0011] Preferably, the cross section of the sliding shaft is convex.

[0025] In the embodiment of the utility model, a driving groove 408 is opened on the inner side of the fixed ring 401, a driving rod 409 is fixedly provided on the outer side of the rotating ring 402, and a blocking rod 410 is fixedly provided on the outer side of the driving rod 409. The blocking rod 410 slides on the outer side of the detection pipeline 2 to facilitate sealing the driving groove 408.

[0026] In the embodiment of the utility model, an arc-shaped opening for the driving rod 409 to pass through is opened on the outer side of the detection pipe 2, so as to facilitate the driving rod 409 to pass through.

[0027] In the embodiment of the utility model, one end of the driving rod 409 away from the fixing ring 401 is spherical, which facilitates the movement of the driving rod 409 .

[0028] In the embodiment of the utility model, the cross section of the sliding shaft 406 is convex, and when the sliding shaft 406 rotates, the arc groove 403 can limit it.
