The second push block 23 is in close contact with the first push block 22, and the hatch door body 2 continues to slide downward, and the sliding speed can be increased. The second inclined surface 28 at the bottom of the second push block 23 pushes the locking rod 17 to slide into the sliding groove 14. The first spring 21 is compressed. Since the second push block 23 is in close contact with the first push block 22, when the second push block 23 slides to the bottom of the locking rod 17, the first push block 22 contacts the locking rod 17 that has not yet extended, and the hatch door body 2 can continue to slide downward to the bottom.
