The guide column 27 and the stop block 28 are designed so that the movable disk 24 can move smoothly relative to the threaded ring 18, and the stop block 28 limits the position of the movable disk 24 to prevent the movable disk 24 from detaching from the guide column 27. When the staff needs to remove the mounting seat 4 from the gastric tube 1, the staff drives the movable disk 24 located in the gastric tube 1 toward the threaded ring 18 through the first through hole 16, and the movable disk 24 slides relative to the guide column 27. The movable disk 24 drives the support sleeve 25 to move, and the inner wall of the support sleeve 25 moves relative to The movable column 20 slides, and the inner wall of the support sleeve 25 pushes the movable column 20 to slide relative to the screw rod 17, so that the support sleeve 25 can completely slide into the second through hole 19, and the movable column 20 drives the guide block 23 to slide relative to the guide groove 22. Through the design of the guide groove 22 and the guide block 23, the movable column 20 can slide smoothly relative to the screw rod 17, and the distance between the two movable columns 20 becomes smaller, the compression spring 21 is in a compressed state, and the end of the support sleeve 25 away from the movable disk 24 is inserted into the avoidance groove 26. When the movable column 20 completely slides into the second through hole 19, the movable column 20 no longer contacts the side of the threaded ring 18 away from the mounting seat 4, and the limitation on the position of the screw rod 17 is released. The staff drives the mounting seat 4 and the screw rod 17 to rotate, so that the screw rod 17 rotates relative to the threaded ring 18, and finally the screw rod 17 disengages from the threaded ring 18, so that the screw rod 17 is screwed out of the gastric tube 1, and the disassembly between the mounting seat 4 and the gastric tube 1 is completed.

[0022] Embodiment 3, based on embodiment 1, Figure 1 and Figure 2 The disassembly and assembly parts include a threaded tube 29 fixedly mounted on the end of the stomach tube 1 facing the injection head 2, a threaded sleeve 30 is sleeved on the outside of the threaded tube 29, and the threaded sleeve 30 is fixedly connected to the injection head 2, a sealing ring 31 is fixedly connected to the end of the threaded tube 29 facing the injection head 2, and the sealing ring 31 is in contact with the end of the injection head 2, the injection head 2 is fixedly mounted with a fixing plate 32, the fixing plate 32 is fixedly mounted with a supporting portion 33, the supporting portion 33 is penetrated by a plug rod 34, and the outer wall of the sealing cover 3 is fixed with a fixing plate 32. A slot 38 is provided to match the plug rod 34, one end of the plug rod 34 is located in the slot 38, the other end of the plug rod 34 is fixedly connected to an iron plate 35, and the iron plate 35 and the support portion 33 are connected by a tension spring 36, a magnet block 37 is fixedly installed on the fixing plate 32, and the magnet block 37 is located on the side of the iron plate 35 away from the support portion 33, a sealing plug 39 is fixedly connected to the sealing cover 3, and the sealing plug 39 is located in the injection head 2, and the sealing cover 3 and the injection head 2 are connected by a connecting rope 40; The staff drives the injection head 2 and the threaded sleeve 30 to rotate so that the threaded tube 29 is no longer located in the threaded sleeve 30, and the sealing ring 31 is no longer in contact with the end of the injection head 2, and the separation between the gastric tube 1 and the injection head 2 is completed. The staff drives the iron plate 35 and the insertion rod 34 to move relative to the support part 33, the tension spring 36 is in a stretched state, and the insertion rod 34 is out of the slot 38, and the limitation on the position of the sealing cover 3 can be released. With the continuous movement of the iron plate 35, the iron plate 35 and the magnet block 37 are magnetically attracted to each other, so that the iron plate 35 and the insertion rod 34 are fixed relative to the fixed plate 32 and the injection head 2.

When the staff needs to remove the mounting seat 4 from the gastric tube 1, the staff drives the movable disk 24 located in the gastric tube 1 toward the threaded ring 18 through the first through hole 16, and the movable disk 24 slides relative to the guide column 27. The movable disk 24 drives the support sleeve 25 to move, and the inner wall of the support sleeve 25 moves relative to The movable column 20 slides, and the inner wall of the support sleeve 25 pushes the movable column 20 to slide relative to the screw rod 17, so that the support sleeve 25 completely slides into the second through hole 19, and the movable column 20 drives the guide block 23 to slide relative to the guide groove 22. Through the design of the guide groove 22 and the guide block 23, the movable column 20 can slide smoothly relative to the screw rod 17, and the distance between the two movable columns 20 becomes smaller, the compression spring 21 is in a compressed state, and the end of the support sleeve 25 away from the movable disk 24 is inserted into the avoidance groove 26. When the movable column 20 completely slides into the second through hole 19, the movable column 20 no longer contacts the side of the threaded ring 18 away from the mounting seat 4, and the limitation on the position of the screw rod 17 is released. The staff drives the mounting seat 4 and the screw rod 17 to rotate, so that the screw rod 17 rotates relative to the threaded ring 18, and finally the screw rod 17 is disengaged from the threaded ring 18, so that the screw rod 17 is screwed out of the gastric tube 1, and the disassembly between the mounting seat 4 and the gastric tube 1 is completed; The staff drives the injection head 2 and the threaded sleeve 30 to rotate so that the threaded tube 29 is no longer located in the threaded sleeve 30, and the sealing ring 31 is no longer in contact with the end of the injection head 2, and the separation between the gastric tube 1 and the injection head 2 is completed. The staff drives the iron plate 35 and the insertion rod 34 to move relative to the support part 33, the tension spring 36 is in a stretched state, and the insertion rod 34 is out of the slot 38, and the limitation on the position of the sealing cover 3 can be released. With the continuous movement of the iron plate 35, the iron plate 35 and the magnet block 37 are magnetically attracted to each other, so that the iron plate 35 and the insertion rod 34 are fixed relative to the fixed plate 32 and the injection head 2. The staff drives the sealing cover 3 to move relative to the injection head 2 to pull the sealing plug 39 out of the injection head 2, and the injection head 2 can be opened. The design of the connecting rope 40 makes the sealing cover 3 and the injection head 2 an integrated design to avoid To prevent the sealing cover 3 from being accidentally lost and the injection head 2 needs to be closed, the staff drives the sealing cover 3 to be mounted on the outside of the injection head 2 again, and the sealing plug 39 is inserted into the injection head 2, so that the end of the injection head 2 away from the gastric tube 1 abuts against the inner wall of the sealing cover 3, and the staff drives the iron plate 35 to move relative to the magnet block 37 so that the iron plate 35 no longer contacts the magnet block 37, and the tension spring 36 applies a pulling force to the iron plate 35 so that the iron plate 35 drives the plug 34 to abut against the outer wall of the sealing cover 3. The staff drives the sealing cover 3 to rotate relative to the injection head 2. When the slot 38 rotates to one side of the plug 34, the tension spring 36 drives the iron plate 35 and the plug 34 to move so that the end of the plug 34 is inserted into the slot 38, which can limit the position of the sealing cover 3 again, thereby reducing the possibility of the sealing cover 3 detaching from the injection head 2 due to non-human factors.
