Blade baffle ring mounting tool

The invention relates to a blade baffle ring mounting tool. The blade baffle ring mounting tool comprises a supporting disc; the supporting blocks are distributed in the circumferential direction of the supporting disc, are movably arranged in the radial direction of the supporting disc and are configured to provide extrusion force towards the radial outer side of the supporting disc; the gears are arranged on the supporting disc in a one-to-one meshing mode to drive the supporting blocks to move in the radial direction of the supporting disc. The supporting block and the gear are arranged on the supporting disc, the gear can be meshed with the supporting block, and the gear can drive the supporting block to move in the radial direction of the supporting disc in the rotating process, extrude the baffle ring outwards and push the baffle ring into the hook groove, so that damage to other parts caused by deformation loss or misoperation of the baffle ring can be avoided, and the assembly operation safety of the
