Example Embodiment
[0035] Example 1
[0036] See figure 2 The roller bracket 5 is installed on the rotating shaft 12 through a fixing member 22, and the roller bracket 5 slides up and down along the fixing member 22; one end of the fixing member 22 is fixedly connected to the rotating shaft 12, and the other end of the fixing member 22 passes through the roller bracket 5. Connected to the fixing part 223; the spring 221 is sleeved outside the fixing part 22, the spring 221 is a compression spring, and the elastic force of the spring 221 keeps the roller bracket 5 away from the rotating shaft and presses the roller bracket 5 along the pipe wall of the pipe 100 Walking; the fixed stopper 223 is used to prevent the roller bracket 5 from ejecting the fixed member 22 under the action of the spring 221;
[0037] The two roller brackets 5 distributed symmetrically along the rotation axis are also connected by a guide post 9, and the two ends of the guide post 9 respectively penetrate the corresponding roll...

[0039] Example 2
[0040] See image 3 The fixing member 22 includes a telescopic member 224 and a telescopic member sleeve 225. The telescopic member sleeve 225 is hollow inside, and the telescopic member 224 is inserted into the telescopic member sleeve 225. The telescopic sleeve 225 is provided with a spring, the end of the spring is fixed on the bottom end of the inner side wall of the telescopic sleeve 225, and the other end of the spring is fixedly connected with the telescopic element 224; the spring drives the expansion and contraction The member 224 is far away from the telescopic member sleeve 225; the telescopic member sleeve 225 is fixedly installed on the rotating shaft 12, and the telescopic member 224 is fixedly connected to the corresponding roller bracket 5.
Example Embodiment
[0041] Example 3
[0042] See Figure 4 The two ends of the fixing member 22 are respectively fixedly connected to two roller brackets 5 symmetrically distributed along the rotating shaft 12. The fixing member 22 includes a telescopic member 224 and a telescopic member sleeve 225. The telescopic member sleeve 225 is hollow and telescopic. The member 224 is inserted into the telescopic member sleeve 225, and the telescopic member 224 and the telescopic member sleeve 225 are axially slid and circumferentially fixedly fitted; the telescopic member sleeve 225 is provided with a spring, and the spring end is fixed on the telescopic member sleeve The bottom end of the inner side wall of the 225 and the other end of the spring are fixedly connected to the telescopic element 224; the spring drives the telescopic element 224 away from the telescopic element sleeve 225; the rotating shaft 12 is fixedly connected to the upper part of the side wall of the telescopic element 224.
