The invention discloses a disc hole lifting appliance which is used for lifting an annular disc, a center hole extending in the axial direction is formed in the middle of the annular disc, and the disc hole lifting appliance comprises a stand column, a lower base, a lower clamping plate and a telescopic part. The stand column is used for being matched with a center hole of the annular disc. The upright post is inserted into the lower seat; the lower clamping plate is arranged on the upper surface, facing the annular disc, of the lower seat, and the lower clamping plate is provided with a placing surface for placing the annular disc; the telescopic part is connected with the lower clamping plate and can control the lower clamping plate to move in the radial direction of the stand column. The stand column is inserted into the lower base, and the telescopic part can control the lower clamping plate to move in the radial direction of the stand column. The placing surface on the lower clamping plate of the disc hole lifting appliance can realize radial extension and retraction, so that the disc hole lifting appliance can penetrate through the center holes of the annular discs with different diameters, and the placing surface can support the annular discs with different diameters.
