Hand-held grinding tool

The invention discloses a hand-held grinding tool, and relates to the technical field of grinding tools, the hand-held grinding tool comprises a fixing block, a storage shell is mounted on the outer wall of one side of the fixing block, a holding rod is mounted on the outer wall of one side of the storage shell, a buffer mechanism is arranged on the outer wall of the bottom of the fixing block, and a first annular groove is formed in the outer wall of the bottom of the fixing block; the buffering mechanism comprises a second annular groove formed in the outer wall of the top of the protection ring, and fixing rods distributed at equal intervals are slidably connected to the inner wall of the second annular groove. According to the polishing device, the buffer mechanism and the protective ring are arranged, and the protective ring enters the first annular groove under the action of a buffer spring during polishing, so that on one hand, the polishing work is met, on the other hand, a gap between the protective
