[0005] Furthermore, an elastic connecting rope is provided between the extrusion plate and the piston, and the extrusion plate slides along with the piston under the action of the elastic connecting rope until it is sealed and fitted with the end of the water suction pipe.
[0006] Furthermore, a collar is installed in the water spray pipe, and the collar is located between the extrusion plate and the water suction pipe. The outer diameter of the collar matches the inner diameter of the water spray pipe, and is sealed and slidably connected to the water spray pipe. The inner diameter of the collar is smaller than the inner diameter of the water suction pipe. When the piston slides toward the extrusion plate and contacts the collar, the collar slides synchronously with the piston. When the piston slides toward the extrusion plate and does not contact the collar, the collar does not slide.
