Folding structure of combined dust collector

The utility model discloses a folding structure of a combined dust collector, which relates to the technical field of dust collectors and comprises a dust collector handle mounted at the top of a dust collector body, and an overturning structure used for folding the dust collector handle is mounted between the dust collector handle and the dust collector body. A buckle structure used for being connected with a dust collector body is installed on the lower portion of an inner cavity of the dust collector handle. According to the technical scheme, when the dust collector handle is folded, the multiple grooves are formed in the circumferential surface of the damping rotating shaft, the balls are installed in the grooves, when the balls make contact with the bottom of the dust collector handle and roll, the folding effect of the dust collector handle can be improved, and meanwhile the dust collector handle can be folded conveniently. The surface friction of the damping rotating shaft can be effectively reduced, s
