• a first sealing plate;
• a second sealing plate, mounted on one side of the first sealing plate, wherein the first sealing plate and the second sealing plate can slide relatively;
• a sealing plate joint, mounted on the first sealing plate, located at one end of the first sealing plate opposite to another end of the first sealing plate where the second sealing plate slides out of the first sealing plate, and provided with a vent hole;
• a connector for connecting the first sealing plate to the sealing plate joint, wherein the first sealing plate and the sealing plate joint can rotate relatively by taking the connector as the axis;
• a first sliding chute, arranged in the first sealing plate, the first sliding chute having an opening facing the second sealing plate;
• a second sliding chute, arranged in the sealing plate joint to engage the first sliding chute;
• a latch, matched with the first sliding chute and the second sliding chute;
• and
• a stop plate, arranged on the first sealing plate and located at a side opposite the first sliding chute, a third sliding chute being arranged in the middle of the stop plate, and part of the first sliding chute being configured to engage the third sliding chute;
• wherein the latch is longer than the second sliding chute, and the latch can access or retreat from the first sliding chute when the sealing plate joint is rotated to be parallel to the first sealing plate;
• and
• the part of the first sliding chute matched with the third sliding chute penetrates the first sealing plate, and the latch penetrates part of the first sliding chute to engage the third sliding chute.
