[0009] Furthermore, the mounting plate and the shock-absorbing and anti-collision mechanism are evenly distributed on the pipeline body in a circumferential manner.

[0010] Preferably, the mounting plate, the anti-collision plate and the clamping plate are all arranged in an arc shape, and the clamping seat is arranged in a U shape.

[0011] The beneficial effects achieved by the utility model using the above structure are as follows:

[0012] 1. The amplitude of the anti-collision plate is absorbed by the expansion and contraction of the damper and the shock-absorbing spring, so as to facilitate the shock absorption and anti-collision protection of the pipeline body;
