[0048] snap spring 7, the snap spring 7 is adapted to be radially elastically deformed, when the snap spring 7 is radially press-fitted in the second clamping groove 62, the small-diameter rod 52 is adapted to move in the rod sleeve 1 with the snap spring 7, when the snap spring 7 moves to the first clamping groove 61, the snap spring 7 is radially reset and enters the first clamping groove 61, at this time, the snap spring 7 is adapted to abut against the front end of the large-diameter rod 51, so as to limit the rod body 5 from moving out of the rod sleeve 1.

[0049] Specifically, as an optional implementation manner in the embodiment, as shown in Figures 2 to 5 , a radial limiting table 53 is arranged at the front end of the large-diameter rod 51, the outer diameter of the radial limiting table 53 is greater than that of the small-diameter rod 52 and less than that of the large-diameter rod 51.
