After the assembly seats A56 and B58 leave the recesses A53 and C55, the assembly seats A56 and B58 are removed from the recesses A53 and C55. The side close to the connecting channel 51 is always embedded in the recess A53, and the side of the assembly seat B58 close to the connecting channel 51 is always embedded in the recess C55. After the walls of the assembly seat A56 and the assembly seat B58 are removed, they still have the function of sealing the recess A53 and the recess C55, thereby preventing air that has not been stripped of dust from flowing out of the connecting channel 51. Similarly, after the assembly seat C510 leaves the recess B54, its side close to the connecting channel 51 is always embedded in the recess B54.

[0041] The assembly seat A56 is fixedly connected to the connecting rod A57 on one side close to the traction part 528, the assembly seat B58 is fixedly connected to the connecting rod B59 on one side close to the traction part 528, and the assembly seat C510 is fixedly connected to the connecting rod C511 on one side close to the traction part 528, so that the traction part 528 can respectively control the assembly seat A56, the assembly seat B58 and the assembly seat C510 through the connecting rod A57, the connecting rod B59 and the connecting rod C511.

[0042] A rectangular opening is reserved on one side of the assembly seat C510, and the stripping net 512 is assembled in the stop opening 513 on the assembly seat C510 through the rectangular opening.

The bending rod 524 is in a skewed state, and the distance between the bending rod 524 and the stop opening 513 becomes larger. At this time, the operator can splice the lower end of the stripping net 512 between the bending rod 524 and the stop opening 513, and then the splicing rod 525 moves toward the outside of the changing opening B520. The linkage piece 526 pulls the rotating disk 522 to rotate, and the rotating disk 522 pulls the guide rod A523 to rotate. The bending rod 524 will lock the side wall of the stripping net 512, so that the stripping net 512 is fastened in the stop opening 513.

The strip groove 538 is located in the center of one side of the inner side of the outer cover 52. The square block is pulled on the traction table 529. As 530 approaches the connecting channel 51, one side of the protrusion gradually moves from the vertical end B532 to the inclined end B533. The inclined end B533 exerts pressure on the side of the moving protrusion, and the strip groove 538 can constrain the connecting strip 534 to ensure that the distance between the protrusion and the connecting channel 51 remains unchanged. Then, when the inclined end B533 exerts pressure on the side of the protrusion, the protrusion moves in the strip groove 538. When the entire traction platform 52 9 When the position of the protrusion changes toward the connecting channel 51, the track B531 can guide the protrusion. When the protrusion moves in the tilted end B533, when the square block 530 changes in the position toward the connecting channel 51, the protrusion slowly moves toward the center of the square block 530, and the connecting strip 534 on one side of the protrusion moves toward the center of the square block 530. The connecting strip 534 on the side of the connecting column will move toward the outer cover 52, and then the assembly seat A56 and the assembly seat B58 are stored in the outer cover 52.

[0046] The traction platform 529 is provided with a housing cavity 535, in which a guide rod B536 is movably installed.

An electric telescopic rod is installed on the upper end of the outer cover 52. The movable end of the electric telescopic rod is connected to the traction platform 529. The electric telescopic rod can be The traction platform 529 is pulled and moved in the outer cover 52. When the entire traction platform 529 moves toward the connection channel 51, the entire assembly seat C510 is embedded in the recess B54. Then the traction platform 529 continues to move toward the connection channel 51. Since the position of the assembly seat C510 is constant, the traction platform 529 moves toward the connection channel 51 to exert pressure on the deformable member 537, causing the deformable member 537 to shorten, and the guide rod B536 to be stored in the accommodating cavity 535.

[0047] During operation, the electric telescopic rod pulls the entire traction platform 529 toward the connecting channel 51, and the entire assembly seat C510 is embedded in the recess B54. At this time, the protrusion moves inside the vertical end B532, and then the traction platform 529 moves toward the connecting channel 51. Since the position of the assembly seat C510 is constant, the traction platform 529 moves toward the connecting channel 51 to form a pressure effect on the deformation member 537, making the deformation member 537 shorter, and the guide rod B536 is stored in the accommodating cavity 535. At this time, the protrusion is inside the tilted end B533. The projection slowly moves toward the center of the square block 530, and the connecting strip 534 on one side of the projection moves toward the center of the square block 530. The connecting strip 534 on the side of the connecting column will move toward the outer cover 52, and then the assembly seat A56 and the assembly seat B58 will be stored in the outer cover 52. Then, while the connecting rod A57 and the connecting rod B59 move toward the outer cover 52, the protruding rod 527 moves along the vertical end A518 toward the inclined end A519. When the protruding rod 527 moves into the inclined end A519, the entire connecting rod 525 moves toward the change opening B520. When the connecting rod A57 and the connecting rod B59 are stored in the outer cover 52, the linkage piece 526 pulls the rotating disk 522 to rotate, and the rotating disk 522 pulls the guide rod A523 to rotate. The bending rod 524 is in a skewed state, and the distance between the bending rod 524 and the stop opening 513 becomes larger. At this time, it is convenient for the operator to assemble and disassemble the stripping net 512. During this period, the assembly seat C510 first strips the air with dust in the connecting channel 51, and then the assembly seats A56 and B58 move towards the outer cover 52. Then, after the stripping net 512 on the assembly seat A56 and the assembly seat B58 is cleaned, the electric telescopic rod pulls the traction platform 529 to move back. At this time, the deformation of the deformation member 537 allows the assembly seat C510 to stop in the recess B54, and the protrusion pulls the assembly seat A56 and the assembly seat B58 into the recess A53 and the recess C55 respectively during the movement in the skewed end B533. Then the traction platform 529 is then retracted and the assembly seat C510 will be removed from the recess B54 and stored in the outer cover 52.
