[0023] Specifically, by rotating the knob 25, since the knob 25 is fixedly connected with the second circular gear 24, the rotation of the knob 25 will drive the second circular gear 24 to rotate synchronously, and the rotating second circular gear 24 is engaged with one of the first circular gears 22, thereby driving the first circular gear 22 engaged therewith to rotate, and since the two first circular gears 22 are fixedly connected through the rotating rod 23, the other first circular gear 22 will also rotate synchronously, and the rotating first circular gear 22 is engaged with the clamping teeth 202 on the outer side of the arc-shaped sliding rod 20, converting the circular motion of the first circular gear 22 into the linear sliding of the arc-shaped sliding rod 20 in the L-shaped sliding groove 101, so that the arc-shaped sliding rod 20 is located at the connection of the first clamping plate 10a and the second clamping plate 10b, increasing the stability of the connection of the first clamping plate 10a and the second clamping plate 10b, and at the same time, as the arc-shaped sliding rod 20 slides towards the pipeline, the rubber strip 21 in the arc-shaped clamping groove 201 gradually closely contacts the surface of the pipeline.
