[0014] In the utility model, when closing the opening, the sealing disk is pulled so that the sealing disk contacts the opening. At this time, the sealing disk is in a horizontal state. Then the hand wheel is turned to drive the worm to rotate, the worm drives the worm wheel to rotate, and the worm wheel drives the turntable to rotate. At this time, the vortex bar matches the claw, pushing the claw to move linearly, so that one end of the claw is inserted into the positioning insert ring. At this time, the opening is closed and fixed by two claws and two positioning insert rings, and the sealing performance is better. When opening the sealing disk, the hand wheel is turned in the opposite direction to move the claw out of the positioning insert ring. At this time, the spring releases the elastic force and pulls the U-shaped bracket to rotate, thereby driving the sealing disk to open automatically, playing an auxiliary opening function and achieving the purpose of quick opening.
