[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0024] The present invention will be further described below with reference to the embodiments.

[0025] Example: Refer to Figures 1 to 4A portable dust collector filter bag includes a dust collector filter bag body 1, an annular fixing plate 2 fixedly mounted on the top of the dust collector filter bag body 1, and a telescopic support mechanism. The telescopic support mechanism includes a telescopic component and multiple support components. The telescopic component includes a cavity 3 disposed within the annular fixing plate 2. A threaded rod 4 is disposed within the cavity 3 and is rotatably connected to the bottom surface of the annular fixing plate 2 via a bearing. A transmission shaft 5 is disposed within the cavity 3 and is rotatably connected to the side wall of the annular fixing plate 2 via a bearing. A first bevel gear 6 is fixedly connected to the side end of the transmission shaft 5, and a second bevel gear 7 is fixedly connected to the top end of the threaded rod 4. Wheel 6 meshes with bevel gear 7. A support cylinder 8 is fixedly connected to the bottom surface of the annular fixed plate 2. A nut 9 is threaded onto the threaded rod 4. Two support columns 10 are fixedly connected to the bottom surface of the nut 9. The two support columns 10 are slidably connected to the bottom surface of the support cylinder 8. An annular support plate 11 is fixedly connected to the bottom end of the two support columns 10. A rotating handle is fixedly connected to the end of the transmission shaft 5 away from the bevel gear 6 for easy use by the operator. The threaded rod 4 and the support cylinder 8 are concentrically arranged. The nut 9 is located inside the support cylinder 8. Both the bevel gear 6 and the bevel gear 7 are located inside the cavity 3.

[0026] The support assembly includes a second support cylinder 12 fixedly connected to the bottom surface of the annular fixed plate 2. A second support column 13 is slidably connected inside the second support cylinder 12. The bottom end of the second support column 13 is fixedly connected to the bottom surface of the annular support plate 11. The first support cylinder 8, the two first support columns 10, and the multiple second support cylinders 12 and second support columns 13 are all located inside the dust collector filter bag body 1. The annular fixed plate 2, the first support cylinder 8, the first support column 10, the second support cylinder 12, the second support column 13, and the annular support plate 11 provide good support for the dust collector filter bag body 1.

[0027] The working principle of this utility model is as follows: When it is necessary to store the dust collector filter bag body 1 to reduce its footprint, the transmission shaft 5 is rotated by turning the handle. The rotation of the transmission shaft 5 drives the first bevel gear 6 to rotate, which in turn drives the second bevel gear 7 and the threaded rod 4 to rotate through meshing transmission. When the threaded rod 4 rotates, the nut 9, under the constraint of the first support cylinder 8 and the two first support columns 10, will engage with the threaded rod 4, and thus move up and down along the threaded rod 4. When it is necessary to store the dust collector filter bag body 1, the nut 9 moves upward, which drives the annular support plate 11 to move upward through the two first support columns 10. The annular support plate 11 will then drive the multiple second support columns 13 to retract into the second support cylinder 12, thereby completing the shrinkage of the support structure, making the length of the support structure smaller, making it easier to store the dust collector filter bag body 1, reducing the space occupied, and making it easier to use.

[0028] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
