At the same time, when the two L-shaped baffles 92 are separated by a certain distance, the top plate 95 is moved upward under the elastic force of the second spring 97. At the same time, under the elastic force of the first spring 94, the top plate 95 is fitted with the inclined plate 98 to seal the top plate 95 and the L-shaped baffle 92.
