The present invention relates to the field of polarizer cutting and processing technology, and specifically proposes a fixture for a polarizer laser cutting machine, including: a fixing table, a flattening end-pull mechanism, a suction and bending reduction mechanism, and a pressing mechanism. The present invention uses the flattening end-pull mechanism to absorb the tops of the four corners of the polarizer, and straightens and flattens the polarizer in the width direction and the length direction, so as to avoid the polarizer placed on the supporting seat from bending and warping, which affects the accuracy of the subsequent cutting size. The flattening end-pull mechanism cooperates with the suction and bending reduction mechanism and the pressing mechanism to perform negative pressure suction and fixation on the flattened polarizer and press during partial cutting, which greatly improves the flatness of the polarizer fixation. The air blowing group cooperates with the coolant to cool the cutting area closed by the pressing mechanism, so as to avoid bending and deformation of the cut part of the polarizer due to temperature changes, thereby improving the polarizer fixation and cutting quality.
