Zusammenfassung:	The utility model relates to the technical field of jigs, in particular to a quick-change jig for TFT (Thin Film Transistor) processing, which is characterized in that at least four positioning blocks are fixed on the upper surface of a base side by side through screws, a quick-change component is fixed on each positioning block through a screw, a plurality of positioning pins are inserted on each quick-change component, and the positioning pins are inserted into the quick-change component. A plurality of vacuum adsorption holes are formed in the upper surface of the quick-change component in a matrix mode, a rectangular vacuum adsorption boss is arranged on the upper surface of the positioning block, a circle of sealing groove is formed in the periphery of the vacuum adsorption boss, the quick-change component is fixed in the sealing groove through screws, and a sealing ring matched with the sealing groove is arranged in the sealing groove. Compared with the prior art, the quick-change jig for TFT (thin film
