1. A detection device comprising:
a collecting chamber configured to collect a fluid sample, the collecting chamber including an opening;
a testing element, arranged in the collecting chamber, configured to test the presence of an analyzed substance in the fluid sample;
a cover body configured to close the opening of the collecting chamber; and
a sample collector, arranged on the cover body and having an absorption element;
wherein the cover body includes an elastic card configured to engage with the opening of the collecting chamber, when the cover body closes the opening of the collecting chamber, the elastic card engages an outer wall of the opening of the collecting chamber, thereby fixing the cover body on the collecting chamber in a clamping way, the sample collector is inserted into the collecting chamber, and the absorption element is compressed such that the fluid sample is squeezed out to flow to a bottom of the collecting chamber and to come into contact with the testing element;
wherein the elastic card includes a buckle structure, an outer wall of the collecting chamber includes a convex structure, and the buckle structure engages the convex structure when the cover body closes the opening of the collecting chamber;
wherein a limiting strip is arranged on the elastic card, when the cover body and the collecting chamber are in a fitted state, the limiting strip and the buckle structure respectively limit the convex structure on the outer wall of the collecting chamber from upper and lower sides, so that the cover body and the collecting chamber are able to be kept stable after being fitted.
