A portion of the outer tube, inserted into the inner tube, is provided with the expanding step 1047 and the O-shaped ring 1048. Another end of the outer tube 1046 is a wine outlet 1051.

(51) In one embodiment of the present invention, the wine spear comprises a wine spear top block 930, a wine spear intake sealing gasket 931, and an internal tube spring 932, an internal tube 933, an external tube spring 934 and an external tube 935 which are arranged from the inside out. The external tube 935 is communicated with the wine spear seat 11. The wine spear top block 930 and the wine spear intake sealing gasket 931 are disposed at the top of the internal tube 933. The bottom of the wine spear top block 930 is connected to the internal tube spring 932. The top of the wine spear top block 930 is moved upward by the internal tube spring 932 to seal the wine spear intake sealing gasket 931. The external tube spring 934 drives the internal tube 933 to move upward to seal the wine spear intake sealing gasket 31 with the external tube 935.

(52) The self-locking non-working state of the dispenser is described below. When the handle is pulled in a direction away from the cam 8019 of the press rod, the handle boss 8025 is disengaged from the counterbore step 8021, and then the handle is rotated downward to drive the rotating pin and the handle boss to rotate about the notch. The handle boss is biased by the spring to lean against the bottom of the press rod. The handle is pressed against the end face of the mounting seat of the dispenser to form a self-locking structure. At this time, the press rod is in a horizontal state. The handle is perpendicular to the press rod. The cam of the press rod maintains in a basic point state. A force exerted by the cam of the press rod on the wine tube connecting seat is zero. At this time, the dispenser shaft is in the initial state, and the dispenser shaft does not contact the check valve B of the connecting tube. Therefore, the check valve B of the connecting tube is closed and the gas in the gas storage tank is sealed in the check valve B of the connecting tube. As shown in FIG. 18, the wine spear intake sealing gasket 931 is to contact and seal against the wine spear top block 930, while the wine spear intake sealing gasket 931 is to contact and seal against the external tube 935.

(53) The working state of the dispenser is described below. When the handle is pulled up to rotate, the rotating pin is driven to rotate about the notch. After the rotating pin is rotated to a certain angle, the handle boss is embedded in the counterbore step of the press rod, so that the handle and the cam of the press rod are rigidly linearly connected. At this time, continuing to rotate the handle upward will drive the press rod to rotate upward, meanwhile, the cam of the press rod will rotate downward. During the downward rotation of the cam, the cam is in contact with the top of the wine tube connecting seat and presses the wine tube connecting seat, thereby driving the dispenser shaft to move downward. When the cam rotates downward to the dead point and the dispenser shaft moves downward a certain distance, a force is applied to the check valve B through the side wall of the dispenser shaft to open the check valve B6002 of the connecting tube, meanwhile, the lower end of the dispenser shaft pushes the wine spear top block 930 and the wine spear intake sealing gasket 931 so that the wine spear intake sealing gasket 931 is disengaged from the wine spear top block 930 and the wine spear intake sealing gasket 931 is disengaged from the external tube 935. At this time, both the gas channel and the outflow liquid channel are open. As shown in FIG. 19, the gas may pass through the gap between the external tube and the wine spear intake sealing gasket 931, and the liquid may pass through the gap between the wine spear intake sealing gasket 931 and the wine spear top block 930. The gas from the gas storage tank enters the alcoholic beverage barrel through the relief valve so that the liquid in the alcoholic beverage barrel is pressurized to flow out from the gap between the wine spear top block and the wine spear intake sealing gasket to get alcoholic beverage.
