The invention relates to a kit structure for accommodating enzyme-linked reagents. The kit structure for placing enzyme-linked reagents includes a kit body, a kit cover connected onto the kit body, and side covers connected with the opposite sides of the kit body, wherein a fixing plate is arranged inside the kit body, through holes I used for fixing diluent reagent bottles, through holes II used for fixing reagent bottles with positive contrasting fluid and reagent bottles with negative contrasting fluid and through holes III used for fixing developing liquid reagent bottles are formed in the fixing plate. Clamping blocks I, clamping blocks II and clamping blocks III connected with springs I, springs II and springs III are arranged on the side walls of the through holes I, the through holes II and the through holes III, and diluent reagent bottles, the reagent bottles with positive contrasting fluid, the reagent bottles with negative contrasting fluid and the developing liquid reagent bottles are clamped through the restoring force from the springs I, the springs II, and the springs III, so that the kit structure solves the problems that the conventional kit cannot fix reagent bolts firmly, and easily causes shaking or breaking of reagent bottles.
