Of course, in other embodiments, the front end of the cylinder can be closed by a sealing plate integrally formed at the front end of the cylinder, in which case the food outlet tube can be fixedly arranged on the sealing plate, and when the liquid food needs to be filled into the cylinder, the liquid food can be sucked by using the screw and the piston, and the liquid food enters the cylinder through the food outlet tube, but the speed of filling the liquid food into the cylinder is relatively slow.

As shown in fig. 2 and 3, the inner cavity of the cylinder 1 includes a first cavity section 6 and a second cavity section 7 connected to the rear end of the first cavity section 6, the first cavity section 6 is cylindrical, the second cavity section 7 is in a truncated cone shape with a small front and a large rear, and the rear end of the second cavity section 7 penetrates through the rear end surface of the cylinder 1, so that the rear end of the cylinder 1 is in an open state. Two half blocks 8 are arranged in the second cavity section 7, each half block 8 is provided with a half screw hole 9, after the two half blocks 8 are closed, the two half screw holes 9 form a screw hole 10, and the two half blocks 8 form a circular truncated cone 11 matched with the second cavity section 7. The rear part of the cylinder 1 is screwed with a threaded sleeve 12, the rear part of the threaded sleeve 12 is concentrically provided with a circular ring 13, a connecting plate 14 is arranged between the rear end of the circular ring 13 and the rear end of the threaded sleeve 12, the connecting plate 14 is circular, the outer edge of the connecting plate 14 is fixedly connected with the threaded sleeve 12, the edge of an inner hole of the connecting plate 14 is fixedly connected with the circular ring 13, and the diameter of the inner hole of the circular ring 13 is larger than that of the screw rod 3, so that the screw rod 3 can smoothly move back and forth in the inner hole of the circular ring 13. The rear end of the ring 13 is fixedly connected to the rear end of the threaded sleeve 12, but in other embodiments, the rear end of the ring 13 may be fixedly connected to the rear end of the threaded sleeve 12 by other structures, such as a block-shaped connecting member or a rod-shaped connecting member. The front end of the circular ring 13 is abutted against the circular truncated cone 11, the front end of the circular ring 13 can abut against the two half blocks 8 in the second cavity section 7, so that the two half blocks 8 form the circular truncated cone 11, and the two half screw holes 9 form the screw holes 10. The piston 2 is in sliding fit in the first cavity section 6, the front end of the screw rod 3 sequentially penetrates through the circular ring 13 and the screw hole 10 and then is connected with the piston 2, and the screw rod 3 is screwed in the screw hole 10.

In order to prevent the screw rod 3 from driving the piston 2 to rotate, the piston 2 is prevented from rotating when moving back and forth, so as to reduce the abrasion of the piston 2, the screw rod 3 is rotatably connected with the piston 2, specifically, a circular box body 15 is arranged in the piston 2, a circular cavity is arranged in the circular box body 15, a circular plate 16 matched with the circular cavity is arranged in the circular cavity, the screw rod 3 penetrates into the circular cavity and is fixedly connected with the circular plate 16, the screw rod 3 can only drive the circular plate 16 to rotate when rotating, and the box body 15 and the piston 2 cannot be driven to rotate.

As shown in fig. 4 and 5, each half block 8 is provided with two receiving holes 17, the two receiving holes 17 are respectively disposed at two sides of the half screw hole 9, the two receiving holes 17 of one half block 8 are directly opposite to the two receiving holes 17 of the other half block 8, for the two receiving holes 17 directly opposite to each other, a compression spring 18 is disposed between the two receiving holes 17, one end of the compression spring 18 abuts against the bottom of one of the receiving holes 17, and the other end of the compression spring 18 abuts against the bottom of the other receiving hole 17. After the circular truncated cone 11 is removed from the second cavity section 7, the two half blocks 8 are separated more easily under the thrust of the compression spring 18.

The cylinder 1 is made of transparent materials, and the surface of the cylinder 1 is provided with scale marks 19. The amount of liquid food filled into the cylinder 1 and the amount of liquid food injected into the patient's stomach can be clearly seen.
