Preferably, the rotating portion includes a first ring groove and a second ring groove which are vertically distributed, a first boss which is slidably fitted to the first ring groove, and a second boss which is slidably fitted to the second ring groove.

Preferably, the first support arm comprises a connecting ring plate fixedly connected to the inner wall of the movable sleeve, and an upper inclined plate and a lower inclined plate which are symmetrically arranged on the connecting ring plate along the edge of the connecting ring plate.

Preferably, the upper inclined plate and the lower inclined plate have included angles a in cross section, wherein 120 ° < a <140 °.

Preferably, the cross section of the second supporting arm is arc-shaped concave towards the connecting column.

Preferably, the cross sections of the upper separation blade and the lower separation blade are triangular, and the area of the triangle is gradually reduced from the connecting column to the direction of the second supporting arm.

Preferably, the cavity may be filled with a gas or a liquid.

The utility model has the beneficial effects that:

compared with the prior art, the utility model decomposes the large sludge transmitted in the pipeline into small sludge by arranging the upper separation blade and the lower separation blade, thereby greatly reducing the probability of pipeline blockage caused by sludge when the pipeline is used; through setting up first support arm and second support arm, can provide certain buffering when the pipeline atress, strengthened the structural strength of pipeline, improved the compressive property of pipeline, effectively prevent that the pipeline from taking place the sunken condition of pipeline when using to the life of pipeline has been prolonged.
