The volume of the dust bag becomes smaller, making it more convenient for people to transport it. The tops of the two force springs 9 are fixedly installed with mounting plates 11, and the top of the mounting plates 11 is provided with extrusion plates 10. In order to limit the extrusion plates 10 and make the extrusion plates 10 more stable when moving, the inner walls on both sides of the installation opening 2 are provided with force springs 9. Limiting grooves are respectively provided on the walls, two L-shaped limiting plates 13 are fixedly installed at the bottom of the extrusion plate 10, and one side of the two L-shaped limiting plates 13 extends into the two limiting grooves respectively, and two vertical plates 21 are fixedly installed at the bottom of the bottom plate 8, and clamping rods 20 are respectively slidably installed on the two vertical plates 21, and the ends of the two clamping rods 20 away from each other extend into the two clamping grooves 19 respectively, and the ends of the two clamping rods 20 close to each other are respectively fixedly installed with circular plates 23, and compression springs 22 are respectively movably sleeved on the two clamping rods 20, and the compression springs 22 make the two clamping rods 20 always be located in the clamping groove 19 without being affected by other external forces, thereby fixing the bottom plate 8. The device is installed on this device, and one end of the two compression springs 22 is fixedly connected to the corresponding circular plate 23, and the other ends of the two compression springs 22 are fixedly connected to the corresponding vertical plates 21. A U-shaped plate 3 is fixedly installed on the top of the workbench 1, and the U-shaped plate 3 is located directly above the installation opening 2. An extrusion roller 4 is rotatably installed in the U-shaped plate 3, and both ends of the extrusion roller 4 extend outside the U-shaped plate 3.

The dust bag is in contact with each other, and then the dust bag is flattened by the extrusion plate 10 and the extrusion roller 4, and the air in the dust bag is completely discharged. The volume of the dust bag becomes smaller, making it more convenient for people to transport it. When the force spring 9 is used for a long time and metal fatigue occurs and needs to be replaced, the rotating handle is turned, and the rotating handle drives the winding rod 14 to rotate. The winding rod 14 drives the pull rope 15 to reel in the two circular plates 23 so that the two circular plates 23 are close to each other. The circular plate 23 moves and drives the two clamping rods 20 to approach each other and move out of the clamping groove 19. People move the vertical plate 21 downward to drive the bottom plate 8 and the force spring 9 to move out of the installation opening 2, and then the force spring 9 that has metal fatigue occurs can be quickly removed from the device for replacement. The process is simple and fast, and the work efficiency is high.
