In addition, the function of the at least two connecting members 13 is to provide a connection, the at least two connecting members 13 are disposed adjacent to the assembly opening 12, the adjacent disposition means that the at least two connecting members 13 are located on one side of the surface of the dust collecting barrel 10 near the assembly opening 12, and the location of the at least two connecting members 13 is sufficient to provide a connection function, and the present utility model is not particularly limited to the location of the at least two connecting members 13. The support ring 30 is a separate component with respect to the dust collecting barrel 10, the support ring 30 is selectively disposed on the dust collecting barrel 10 and can be separated from the dust collecting barrel 10, the support ring 30 has a ring inner diameter 31 and a ring outer diameter 32, and the ring inner diameter 31 is larger than the caliber 121, so that the support ring 30 is assembled on the top edge 101 of the shell member when the support ring 30 is assembled with the dust collecting barrel 10, and is disposed at the assembling port 12. The dust collection assembly 50 includes an assembly housing 51 and at least two engaging structures 53 formed on the outer surface of the assembly housing 51, wherein the assembly housing 51 can be selectively assembled with the support ring 30, and is positioned on the dust collection barrel 10 when the assembly housing 51 is connected with the support ring 30, and is removed from the dust collection barrel 10 when the assembly housing 51 is separated from the support ring 30. The at least two engaging structures 53 are matched with the at least two engaging members 13, and the at least two engaging structures 53 provide the at least two engaging members 13 for assembling so as to limit the dust collection assembly 50 from being separated from the dust collection barrel 10 during use. Further, the assembly housing 51 has at least one housing outer diameter 511, the at least one housing outer diameter 511 being smaller than the bore 121 but larger than the ring inner diameter 31. In one embodiment, the outer diameter 511 of the housing is a single design, meaning that the component housing 51 does not have an outer diameter variation, and in another embodiment, the outer diameter 511 of the housing is a plurality of designs, meaning that the component housing 51 has an outer diameter variation, and each of the plurality of housing outer diameters 511 is less than the bore 121 but greater than the inner diameter 31.
