The utility model discloses a tool clamping device for a tool magazine of a numerical control machine tool, and relates to the technical field of numerical control machine tool equipment. The limiting ring is fixed at one end of the mounting plate; and the clamping device is arranged on the outer side of the limiting ring, penetrates to the inner side of the limiting ring and is used for clamping a cutter. The clamping device is arranged, the threaded sleeve is rotated, the threaded sleeve rotates to move along the lead screw, and therefore the distance between the positioning plate and the inner wall of the limiting ring is adjusted to be equal to the radius of a cutter needing to be placed, and when the cutter is put down from the top of the limiting ring, the cutter can move to the center of the limiting ring along the guide plate; and at the moment, a first telescopic spring pushes a clamping block to clamp the cutter, so that a central shaft of the cutter is aligned with a central shaft of a limiting rin
