Pipeline alignment structure and alignment pipeline thereof

The invention provides a pipeline alignment structure and an alignment pipeline thereof. The alignment pipeline is arranged on an outer shell and used for being connected with a communicating pipe, and the communicating pipe is provided with a communicating pipe axis. The alignment pipeline comprises a pipe body, a connecting piece and a plurality of balls. The pipe body is provided with a pipe body axis and comprises a first end and a second end opposite to the first end. The first end can be connected with a communicating pipe. The connecting piece surrounds the pipe body and is arranged at the second end, and the connecting piece is movably connected with the outer shell. The balls are arranged on the connecting piece in a rolling and scattered mode, at least part of the balls make contact with the outer shell, so that the connecting piece can move in the radial direction of the axis of the pipe body relative to the outer shell, and therefore when the communicating pipe is inserted into the first end, the
