Summary:The invention discloses a sampling device of a gaseous sample for environmental detection.The sampling device comprises a sampling box, and a servo motor is fixedly connected to the bottom of an inner cavity of the sampling device.According to the sampling device, a plurality of protection cylinders are arranged, so that a plurality of sampling tasks can be set, and the multiple protection cylinders are used for storing the sampled gaseous sample; by arranging the protection cylinder, the protection cavity, the sampling cylinder and the liquid cavity and inputting carbon dioxide into the protection cavity, the leakage of the protection cylinder, the leakage of the first connecting valve, the leakage of the protection cylinder and the sampling cylinder and the leakage of the sampling cylinder can be detected; the influence of the external temperature on the gaseous sample stored in the sample storage cavity can be reduced through carbon dioxide, and the protective cylinder can be repeatedly used, so that the u
