The application relates to the marker detection field and specifically relates to a
colorectal cancer tumor marker detection device, which comprises a tray, the tray comprises a bottom plate and a plurality of transverse plates and longitudinal plates arranged on the bottom plate, the transverse plates and the longitudinal plates are vertically staggered to form a plurality of rows of placement grooves, and
enzyme strips are placed in the placement grooves; a sliding hole is formed in the end of each transverse plate, a sliding groove is formed in the position opposite to each placement groove, and the sliding groove is communicated with the sliding hole and the placement groove; in the application, the designed tray is matched with the
enzyme strips, a push rod is arranged in the tray, the push rod is matched with a limiting structure, the
enzyme strips are extruded and fixed in the placement grooves, meanwhile, the placement grooves are emptied, the enzyme strips can be conveniently taken out from the placement grooves in an inclined state, and the operation of a detection personnel on a detection process is facilitated.
