The utility model relates to a PVC pipe annular cutting machine in the technical field of cutting machines, a telescopic dust removal mechanism comprises a second bevel gear connected with a first bevel gear in a meshed mode, and a rotating shaft used for rotating along with the second bevel gear is connected to the middle of the second bevel gear in an inserted mode. A rotating cylinder used for synchronously rotating along with the third bevel gear is inserted into the middle of the third bevel gear, and a screw used for stretching out and drawing back when the rotating cylinder rotates is connected into a cylinder cavity of the rotating cylinder in a threaded mode. After the PVC pipe is cut, a second motor can be driven, a transmission shaft is driven by the second motor to rotate, so that a rotating cylinder rotates, a screw rod can extend rightwards under the rotation of the rotating cylinder, then a horn mouth extends into a cavity of a working frame, and under the action of a dust collector, chippings
