The utility model relates to an end member variable hyperspectral image spectrum hybrid analysis device which comprises a shell, a spectrum analysis module is arranged in the shell, the spectrum analysis module is installed on a PCB, and the shell comprises a shell body, an end front cover and an end rear cover; the shell body is formed by sequentially connecting a left side wall, a right side wall, an upper side wall and a lower side wall end to end. Grooves are symmetrically formed in the left side wall and the right side wall, the axial directions of the grooves are the front-back direction, the sections of the grooves are circular, the grooves are pulled through at the front end of the shell body, the grooves are not pulled through at the rear end of the shell body, internal thread sections are arranged at the upper ends of the grooves, studs are arranged at the internal thread sections, and screwdriver inserting grooves are formed in the outer end faces of the studs; columns are arranged at the two ends of the PCB and inserted into the grooves. The spectral analysis module is packaged by adopting an independent shell, and the PCB and the shell are buckled through the groove with the circular section and the cylinders at the two ends of the groove, so that the PCB is installed in the shell more firmly.
