[0015] The novel non-destructive HPV cervical sampling tube is provided with a sampling tube, a protective head, a one-way rubber membrane flap, a pushing tube, a connecting tube, a sampling swab, a rotating groove and a breaking component. When sampling the female cervix, the top of the sampling swab passes through the inner side of the bottom of the protective head and the inner side of the one-way rubber membrane flap, and then passes through the sampling tube and is plugged into the connecting tube at the bottom of the pushing tube. Then, the pushing tube is rotated outside the sampling tube and moved upward, so that the sampling swab head is placed inside the protective head. Then, the sampling tube is held in the hand to directly reach the cervix with its soft and skin-friendly protective head. Then, the sampling swab inside the protective head is slowly and rhythmically pushed out by rotating the pushing tube to sample the cervix, thereby greatly preventing the sampling swab from touching the cervix. It can effectively protect the female vagina from scratches. After the sampling is completed, the sampling tube is pulled and the pushing tube is rotated to make the sampling swab return to the inside of the protective head and then continue to pass through the one-way rubber membrane flap, and then reach the inside of the sampling tube. At this time, the one-way rubber membrane flap is closed inside the protective head, thereby protecting the sampling swab and avoiding contamination, which is beneficial for subsequent detection and use. When the sampling swab needs to be detected and used later, it is only necessary to pull the positioning rod at the top of the pushing tube to disengage from the restriction of the block. The block is violently pushed by the telescopic spring column, so that the clamping knife on the inside of the block can clamp and cut off the sampling swab, and then the protective head at the bottom of the sampling tube is removed, and the sampling swab can be taken out for detection and use.
