After the second docking block 17 is moved according to the diameter of the barrel body, the angle of the second fixing frame 13 relative to the first fixing frame 11 is changed, so that the barrel body is clamped, and the sealing gasket 33 is pressed on the outside of the crack of the barrel body for shielding and sealing.
