The movable hose 91 drives the air inlet cover 92 into the fixing ring 911. After the battery 12 is electrically connected to the air pump 5, the air pump 5 is started to extract the powdered composite material in the feeding frame 10 through the air inlet pipe 8, the movable hose 91 and the air inlet cover 92. Then it is discharged to the outside through the air outlet pipe 7. When it is not needed, the movable air extraction component 9 can be placed into the placement frame 6 for use.
