6, 6 left ends of drain pipe run through shell 1 and the coaxial hose 7 that is equipped with, the cover is equipped with the rectangular shell 8 of fore-and-aft direction on the hose 7 outer fringe face, be.

In order to facilitate the injection tube 2 to extract the liquid food from the liquid food bottle 19, the liquid inlet pipe 5 is internally provided with a first one-way valve 10 with an opening facing the injection tube 2.

In order to facilitate the liquid food to flow out of the liquid outlet pipe 6, a second one-way valve 11 with an opening facing the hose 7 is arranged in the liquid outlet pipe 6.

In order to facilitate the piston rod 3 to slide in the injection tube 2, the front side wall of the shell 1 is provided with a left-right direction and front-back through abdicating groove 12, the front end of the disc 13 is provided with a handle 15 extending out of the abdicating groove 12, and the handle 15 can slide left and right in the abdicating groove 12.

In order to realize the fore-and-aft sliding of the stop block 9 in the rectangular shell 8, the front side wall of the rectangular shell 8 is in threaded connection with a screw rod 16 in the fore-and-aft axial direction, and the rear end of the screw rod 16 is in rotary connection with the stop block 9.
