Rotatable grinding wheel clamping hanging bracket

The utility model relates to the technical field of grinding wheel lifting appliances, in particular to a rotatable grinding wheel clamping lifting frame which comprises a connecting block, two connecting rods are hinged to one side of the connecting block, clamping arms are hinged to one sides of the two connecting rods respectively, an air cylinder is hinged between the two clamping arms, and the air cylinder is hinged to the other side of the connecting block. And one side of each clamping arm is fixedly connected with a sleeve, and the interior of each sleeve is rotationally connected with a rotating shaft. The grinding wheel clamping device has the advantages that the sleeves are installed on the two clamping arms, the rotating shaft can be rotated by holding the handle with a hand through rotating fit of the rotating shaft and the sleeves, so that the clamping plate is driven to rotate, and when a grinding wheel needs to be installed, the rotating shaft is rotated to enable the grinding wheel to be chan
