The invention discloses a sample tray structure for an atomic fluorescence photometer, which is convenient to use. The sample tray structure comprises an upper tray and a lower tray, wherein a plurality of sample tubes are inserted into the upper tray; and the upper tray comprises an upper disc and a plurality of jacks uniformly formed in the upper disc. The invention relates to the technical field of atomic fluorescence photometers. The sample tray structure for atomic fluorescence photometer is convenient to use. dividing the sample tray into upper tray and lower tray which can be separated, at the same time, the whole sample disk can be directly taken out from the photometer, as a storage container for storing sample tubes during sampling, no need of transfer operation after sampling, The sample tray and the sample can be directly put into the photometer for detection, so that the efficiency is improved; and the upper tray and the lower tray are connected through the arc-shaped supporting frame matched with the clamping sleeve, so that the upper tray and the lower tray can be combined and separated through the simple operation of rotating and lifting, the upper tray and the lower tray are convenient to store and carry, and the operation is simple and convenient.
