When the motor shaft is clamped and fixed, the rotating disk is first rotated to move the limit rod in the limit groove, and then the movable rod drives the clamping block and the movable contact block to approach each other. Under the cooperation of the clamping block, until the movable contact block is in conflict with the surface of the motor shaft, the limit rod is fixed by the locking nut, so that the two ends of the motor shaft can be quickly contacted and fixed. After the motor shaft is in conflict and fixed, when rotating and grinding, with the rotation of the motor shaft, under the cooperation of the inclined groove, the slide groove, the guide column and the slide plate, the movable contact block can move along with the torsion of the motor, so that the movable contact block is always in close contact with the surface of the motor shaft, thereby effectively fixing the motor shaft, which is convenient for the subsequent precise grinding of the motor shaft.
