Constant temperature and humidity chamber test fixture

The utility model belongs to the technical field of detection equipment, particularly relates to a constant-temperature and constant-humidity chamber test fixture, and aims to solve the problems that internal detection products are inconvenient to place due to the fact that the distance between existing placing plates is small, and the detection products are easy to fall off in the moving process if the detection products are placed on the placing plates externally and then placed in a constant-temperature and constant-humidity chamber, so that the detection products are inconvenient to move. According to the technical scheme, the constant-temperature constant-humidity box comprises a constant-temperature constant-humidity box body, the inner walls of the two sides of the constant-temperature constant-humidity box body are each fixedly provided with two connecting strips, and a containing frame used for containing detection products is connected between the two connecting strips in an inserted mode; the placi
