Longitudinal rotation grooves 1 are arranged inside both ends of the two upper fixing rings 10 that are close to each other. The rotation grooves 1 penetrate through the outer arc wall of the upper fixing ring 10. The locking mechanism 20 includes a fixing column 1 21 rotatably connected to the inner arc wall of the rotation groove 1. On one side wall of the fixing column 1 21 close to the center of the inside of the upper fixing ring 10, a turntable 23 is fixedly connected. At the top and bottom of one side wall of the turntable 23 close to the fixing column 1 21, fixing columns 2 22 are fixedly connected. Both of the two fixing columns 2 22 are located outside the fixing column 1 21. On one side wall of the turntable 23 away from the fixing column 1 21, a fixing column 3 24 is fixedly connected. A slide rail spring 25 is sleeved on the outer arc wall of the fixing column 3 24. The slide rail spring 25 is V-shaped. One end of the slide rail spring 25 is sleeved on the outer arc wall of the fixing column 3 24. The other end of the slide rail spring 25 internally sleeves a fixing column 4 26. At the center of one side wall of the fixing column 1 21 away from the turntable 23, a triangular groove 1 is arranged.

[0032] It should be noted that, in fact, both the upper fixing ring 10 and the lower fixing ring 11 are semi-circular rings, and the upper fixing rings 10 and the lower fixing rings 11 on both sides are symmetrically arranged. When the two upper fixing rings 10 and the lower fixing rings 11 are in contact with each other, they can form a complete ring.

[0033] Refer to Figure 1-7 As shown in the figure, on the side of the rotation groove 1 arranged on the upper fixing ring 10 close to the center of the inside of the upper fixing ring 10, a rotation groove 2 is arranged. The rotation groove 2 communicates with the rotation groove 1. On the side of the rotation groove 2 close to the rotation groove 1, an annular rotation groove 3 is arranged.

Then, insert a suitable triangular tool into the equilateral triangular groove and rotate it to drive the locking mechanism 20 to lock the upper fixing ring 10. Subsequently, pull out the fixing plate 13, pull the damping telescopic rod 12 and rotate it to activate the limiting mechanism 30, and the limiting roller 35 extends out to abut against the outer arc wall of the pipeline. Then, insert the fixing plate 13 into the corresponding slot for fixation. At this time, the driving mechanism 40 on one side of the lower fixing ring 11 can move in the tooth groove to inspect the pipeline in a circular manner, and at the same time, the limiting roller 35 can enable the device to move axially on the outer arc wall of the pipeline.
