A method for sampling a compound carpet thickener, used in a sampling device for detecting a compound carpet thickener as claimed in claim 8, characterized in that: The following steps are involved: S1: rotating the threaded column (8) to drive the clamping plate (5) to move, so that the clamping seat (4) and the clamping plate (5) can be clamped on the edge of the barrel (38); S2: The sampling rod (1) is then pressed so that the extended piece (28) on the sampling head (2) fits against the inner wall of the barrel (38) and moves to the lower part of the barrel (38); S3: The main push sheet frame (16) is then pushed to drive the arc-shaped sheet (36) to move downward and the sampling sheet (25) to extend from the interior of the sampling head (2) so that the compound carpet thickener on the inner wall of the barrel (38) is sealed between the extending sheet (28), the arc-shaped sheet (36) and the sampling sheet (25), thereby completing the sampling.
