A first movable seat 40 is connected to a first drag chain 43. The two ends of the first drag chain 43 are respectively connected to the first movable seat 40 and the first drag chain plate 80, and bend as the first movable seat 40 moves, ensuring that the first drag chain 43 can adapt to the change in position of the first movable seat 40.
