[0065] In this embodiment, the rotation axis of the pipeline movable member, the rotation axis of the movable slot, and the rotation axis of the rotating assembly do not coincide due to machining errors, installation errors, and rotation wear. The chain carrier is added to the pipeline movable assembly, and the floating shaft is added to the second end of the pipeline movable member, which is slidably connected to the first end of the chain carrier to prevent the rotation axes from not coinciding, so that the pipeline movable member is not damaged when moving.

[0068] The floating shaft 22a is movably arranged in the bearing hole through the linear bearing 231.

[0069] In this embodiment, the floating shaft moves smoothly in the bearing hole through the linear bearing; when the rotating assembly drives the pipeline movable member to bend and rotate, it flexibly compensates for the error of the non-coincidence of the rotation axes of the pipeline movable member, the movable slot, and the rotating assembly, prevents jamming or damage caused by rigid connection, and has a simple structure and is easy to implement.

[0070] More preferably, referring to Figure 4 , the number of bearing holes and floating shafts 22a is two, and two coaxial linear bearings 231 are arranged in each bearing hole.
