Zusammenfassung:	The invention relates to a sampling device for exhaust particles of an engine. The sampling device is characterized in that a lower cover is arranged inside a casing pipe of a base and can move up and down; an upper cover and the lower cover are automatically compacted by springs; and filter paper installing plates are arranged between the upper cover and the lower cover. When the springs are compressed, the upper cover, the filter paper installing plates and the lower cover are sealed; exhausts of the engine inflow, the exhaust particles are filtered by filter paper, and the exhausts outflowthrough the lower cover and the casing pipe of the base; the multiple filter paper installing plates are arranged on the same turntable; the turntable can rotate around a fixing shaft parallel to themiddle axes of the upper cover and the lower cover; when a certain amount of particles are collected, the springs are compressed again so as to lead the upper cover, the filter paper installing plates and the lower cover from
