Automatic sampling device for chemical product detection and use method thereof

The invention discloses an automatic sampling device for chemical product detection and a use method thereof, and relates to the technical field of chemical product detection. The device comprises a sampling body, a sampling bin is arranged in the sampling body, a transmission mechanism is arranged in the sampling body, the transmission mechanism comprises a first connecting rod arranged in the sampling body, the first connecting rod is rotatably mounted on a second connecting rod, and a first lantern ring is fixedly mounted on the second connecting rod; a first protruding block is fixedly installed in the first lantern ring, and a first clamping block is fixedly installed on the first connecting rod. According to the chemical product sampling device, the first connecting rod is rotated to drive the transmission mechanism to rotate, so that the control mechanisms move towards the outer side of the sampling body, a to-be-detected chemical product can be sampled, and due to the fact that the heights of the cont
