[0038] Specifically, when replacing the mixing tank 2 and the agitator 4, it is first necessary to insert the mounting pin 5 connected to the top of the agitator 4 into the threaded column 6 and the spring clip 9, and then apply force by rotating the knob 7 to drive the threaded column 6 to rotate inside the connecting column 3. This rotation process relies on the threaded cooperation between the threaded column 6 and the connecting column 3, so that the threaded column 6 moves inside the connecting column 3. During the movement of the threaded column 6, it will press the clip 10 inside the connecting column 3, and then compress the spring clip 9 connected at the top. This compression process causes the clip 10 to tighten toward the middle, thereby firmly fixing the mounting pin 5, so that the mixing tank 2 can be quickly disassembled and assembled for easy replacement.

[0039] Reference Figure 1 , Figure 4 and Figure 5The fixing component includes a first connecting tube 12, the first connecting tube 12 is fixedly connected to one end of the first air pipe 11, the first connecting tube 12 is slidably connected to the inside of the second connecting tube 13, one end of the second connecting tube 13 is fixedly connected to the second air pipe 14, the first connecting tube 12 is slidably connected to the inside of the first sliding column 15, the outer wall of the first connecting tube 12 is slidably connected to the ring 21, the outer wall of the first connecting tube 12 is sleeved with a third spring 22, one end of the third spring 22 is fixedly connected to the inside of the ring 21, and the first connecting tube 12 is slidably connected to the inside of the first connecting tube 12.

[0040] Specifically, in the process of realizing the quick connection of the first air pipe 11 and the second air pipe 14, firstly, by pulling the ring 21 and utilizing the contraction of the third spring 22, the card bead 23 inside the first connecting tube 12 is released, and then the second connecting tube 13 connected to the second air pipe 14 is inserted into the first connecting tube 12 connected to the first air pipe 11, thereby achieving the effect of quick connection.

[0043] Working principle: when the mixing tank 2 and the agitator 4 need to be replaced, first insert the mounting pin 5 connected to the top of the agitator 4 into the threaded column 6 and the spring piece 9, then turn the knob 7 so that the force drives the threaded column 6 to rotate inside the connecting column 3, and the threaded column 6 moves inside the connecting column 3 through the threaded relationship between the threaded column 6 and the connecting column 3. During the movement of the threaded column 6, the clip 10 inside the connecting column 3 will be squeezed, and the clip 10 will be forced to drive the spring piece 9 connected to the top to shrink, so that the clip 10 is tightened toward the middle to fix the mounting pin 5, so that the mixing tank 2 can be quickly disassembled and assembled for easy replacement. When the first air pipe 11 and the second air pipe 14 need to be connected, first pull the collar 21 so that the force squeezes the third spring 22 to shrink, thereby releasing the card bead 23 inside the first connecting pipe 12, and then insert the second connecting pipe 13 connected to one end of the second air pipe 14 The first connecting tube 13 is connected to the second connecting tube 13 by the force of the second connecting tube 19, and the second connecting tube 13 is connected to the second connecting tube 13 by the force of the second connecting tube 19.
