This utility model relates to a telescopic disposable fecal sampling tube, comprising a container body, a sampling tube, and a sealing cap. The sampling tube has a telescopic structure, which includes a first sleeve, a second sleeve, and a third sampling rod that are slidably inserted in sequence, forming a telescopic sampling tube structure with adjustable length. The top end of the first sleeve is fixedly connected to the sealing cap, and the front end of the third sampling rod is provided with a sampling head. The sealing cap is screwed to the upper opening of the container body. This utility model's sampling tube achieves automatic extension and retraction of the sampling head through a telescopic mechanism, eliminating the manual alignment step and reducing the probability of misoperation, thereby reducing the probability of contact with fecal samples. It is particularly suitable for collecting fecal samples from toilets. The sealing cap prevents sample contamination during transmission and avoids environmental pollution. The groove design of the sampling head increases the number of samples obtained per unit area, improving work efficiency.
