[0023] A liquid filling gun composed of a liquid filling gun head includes the above-mentioned liquid filling gun head, the liquid filling gun head is installed at the bottom end of the liquid filling gun, the interior of the top plate 1 is slidably connected to a liquid filling tube 12, the outer wall of the liquid filling tube 12 is fixedly connected to a pressure plate 13, the liquid filling tube 12 is slidably connected to the interior of the bottom plate 3, the liquid filling tube 12 is slidably connected to the interior of the adjustment plate 7, and the liquid filling tube 12 is slidably connected to the interior of the gun head tube 10, and liquid filling is performed through the liquid filling tube 12.

[0024] The outer wall of the top plate 1 is rotatably connected to a handle 14, and the interior of the handle 14 is fixedly connected to a connecting shaft 15. The outer wall of the connecting shaft 15 is rotatably connected to a rotating rod 16, and the rotating rod 16 is rotatably connected to the interior of the pressure plate 13. By pressing down the handle 14, the rotating rod 16 is driven to rotate an angle, thereby achieving the effect of driving the pressure plate 13 to press down. The outer wall of the liquid filling tube 12 is sleeved with a spring 2 17, one end of the spring 2 17 is fixedly connected to the interior of the pressure plate 13, and the other end of the spring 2 17 is fixedly connected to the interior of the bottom plate 3.

At this time, press the two sliding pins 9 at the same time to make the sliding pin 9 drive the card block 8 to slide to the middle, thereby making the card block 8 slide out of the inside of the adjustment plate 7. At this time, press the sliding pin 9 while sliding downward to disassemble the gun head tube 10. After cleaning, use the same method to press the sliding pin 9 to place the card block 8 in the middle position, and fit the upper end of the gun head tube 10 with the lower end of the adjustment plate 7. After loosening the sliding pin 9, the automatic reset effect of the spring 11 is used to drive the sliding pin 9 to slide to both sides, thereby making the card block 8 slide to both sides and be stuck in the inside of the adjustment plate 7 for fixation, thereby achieving the effect of quick disassembly and assembly.
