[0028] Further, by the user driving the annular sealing gasket 3 to move the two fixed blocks 6 downward, the fixed blocks 6 will then fall into the inside of the two through grooves 4, so that the arc-shaped ends of the two moving blocks 12 contact the inner wall of the annular groove 5, then press the annular sealing gasket 3, so that the two moving blocks 12 will squeeze the two compression springs 13, so that the two moving blocks 12 will completely shrink into the inside of the two sliding grooves 11, then the annular sealing gasket 3 will fall into one end of the annular retainer 8, then use the two fixed plates 16 to rotate the annular sealing gasket 3 to make the two fixed blocks 6 slide around the inner wall of the annular groove 5, then use the two fixed plates 16 to drive the two moving blocks 12 to move inside the annular groove 5, then when the two moving blocks 12 move to the inside of the two corresponding arc-shaped grooves 7, the two moving blocks 12 will enter the inside of the two arc-shaped grooves 7, so that the two moving blocks 12 can be fixed inside the annular groove 5.
