The utility model relates to a fixture for laser machining micropores of fuel injection discs, wherein a rotating disc comprises an upper disc seat and a lower disc seat which are connected into a whole through an intermediate journal, a plurality of fuel injection disc placing holes are distributed along the circumferential direction on the upper disc seat, and a circular groove is arranged on the lower disc seat below one fuel injection disc placing hole, and auxiliary parts are arranged in the circular groove; The support seat consists of a left half support part and a right half support part which are assembled in pairs, wherein the middle part is provided with a shaft hole for matching with the middle journal of the rotating disc, and the left half support part is provided with a processing hole which is just opposite to the circumferential movement track of the fuel injection plate placing hole, and the movable support is installed in the processing hole from below and can move up and down; The rotating platform is in driving connection with the rotating disc. When the ball head in the circular groove on the lower disc seat is aligned with the movable support, the movable support is lifted up. A movable support is arranged right below the machining hole to position the oil injection piece; Auxiliary parts of the lower disc seat realize the vertical up-and-down movement of the movable support.
