In one embodiment, at least one of the plurality of connecting arms 40 is hingedly connected to the first connecting portion 30. During the movement of the transportation mechanism along the pipe 20, if the connecting arm 40 is pressed or released, a rotation may occur, which may cause the transportation mechanism to adapt to changes in the pipe diameter of the pipe 20, or to make a turn at the bend of the pipe 20, etc.
