The negative pressure adsorption port 771 is adjacent to the nozzle 755 ; the cross section of the nozzle 75 is tapered toward one side of the nozzle 755 A first reduced diameter channel 751 is formed, and the nozzle 755 is formed at the narrowest point, which is shaped like a tapered tube. The cross section of the infusion pipe 77 is tapered toward the side of the negative pressure adsorption port 771 to form a second reduced diameter channel. 775, the negative pressure adsorption port 771 is formed at the narrowest point, and its shape is like a long and narrow tapered tube.

Please refer to Figure 1, Figure 4, Figure 5, and Figure 7.

When the pumped gas is continuously ejected from the reduced diameter channel of the nozzle 75 through the nozzle 755, the high-speed jet passes near the negative pressure adsorption port 771 and then passes through the nozzle 755. The gas that is ejected and flows continuously at high speed will produce a pressure decrease (pressure difference) near the negative pressure adsorption port 771 , thereby generating an adsorption effect at the negative pressure adsorption port 771 .
