[0022] See also Figure 1 , Figure 3 , Figure 4The disassembly mechanism 3 includes a limit seat 31, and the interior of the nozzle 2 is slidably connected with a plurality of evenly distributed limit seats 31. A spring 32 is arranged inside the nozzle 2. A limit ring 33 is fixedly connected to the outer side of the feeding pipe 1, and a plurality of evenly distributed limit columns 34 are fixedly connected to one end of the nozzle 2 close to the limit ring 33.
