As a further improvement of the technical scheme, the bottom end edge of the pipe body is bent inwards to fix the plugging piece in the pipe body.
As a further improvement of the above technical solution, the flange of the blocking piece faces the bottom end of the tube body.
As a further improvement of the technical scheme, the pipe body is provided with the air outlet, the top end of the pipe body is provided with the connector, the connector comprises the air inlet nozzle, the right end of the air inlet nozzle is provided with the sealing gasket, and one side of the sealing gasket is in sealing butt joint with the top end of the pipe body.
As a further improvement of the technical scheme, the connector further comprises a screw cap and an external thread pipe, the air inlet nozzle is inserted into the screw cap, the other side of the sealing gasket is in sealing butt joint with the screw cap, the external thread pipe is sleeved on the pipe body, and the screw cap is in threaded connection with the external thread pipe.
As a further improvement of the technical scheme, the top end of the pipe body is outwards turned into a flanging.
The beneficial effects of the utility model are as follows: through set up the shutoff piece that the processing was the lid in advance in the body, have certain area of contact before shutoff piece and the body, seal stability is strong to this structure processing is convenient.
