Biological chip detector

The invention discloses a biological chip detector. The biological chip detector comprises a first shell and a second shell which are connected with each other, as well as a biological chip supporting rack, a light source, a detector and a detection result output device, wherein the first shell is provided with an accommodating cavity; an upper plate of the accommodating cavity is opposite to the second shell; the biological chip supporting rack is rotatably arranged on the upper plate of the first shell, and is provided with a detection zone for placing a biological chip; the upper plate is provided with a through hole corresponding to the detection zone; the light source is positioned on one of the first shell and the second shell and used for providing light for the biological chip; the detector is mounted on the other of the first shell and the second shell and is used for detecting a detection part of the biological chip; the detector and the light source are arranged on the two sides of the biological chip supporting rack. The biological chip is put on the biological chip supporting rack, the detection part of the biological chip can be corresponding to the through hole, the light source is turned on as required, and the detector detects the detection part of the biological chip so as to complete detection on a biological substance. The biological chip detector is simple structure, small in space occupation and convenient to carry, and facilitates detection works outdoors and in remote regions, so that the application range of the biological chip detector is widened.
