1. A strip cutting device for a diagnostic kit, which is adapted to cut a diagnostic sheet (10) provided to the shape of a band into a plurality of strips (11) in a transverse direction at once, the strip cutting device comprising: a frame (100); a first shaft (200′) having a plurality of disc-shaped blades (210′) and spacers (210″) alternately fixedly fitted thereto, without rotating, and an adjustment nut (230) fastenedly fixed to one side thereof to fix the blades (210′) and the spacers (210″) thereto, and a second shaft (200″) having a plurality of disc-shaped blades (210′) and spacers (210″) alternately fixedly fitted thereto, without rotating, and an adjustment nut (230) fastenedly fixed to one side thereof to fix the blades (210′) and the spacers (210″) thereto, wherein as the first shaft (200′) and the second shaft (200″) are mounted on the frame (100) to rotate in position together, the blades (210″) cut the diagnostic sheet (10) into the plurality of strips (11) by means of the shear forces thereof, the first shaft (200′) and the second shaft (200″) each having at least two or more concentricity adjustment screws (231) fastened on an imaginary circle with respect to the center thereof to each adjustment nut (230) fastenedly fixed thereto to pressurize the blades (210′) and the spacers (210″) in a transverse direction and thus to adjust the concentricity of the blades (210′) and the spacers (210″), and the spacers (210″) fitted to the first shaft (200′) and the second shaft (200″) each having a projection (214) with a given distance (W) formed on the surface facing the surface of each blade (210′) where a cutting edge is formed.
