In the initial state of the sampling tube 100, as shown in fig. 1, the cover 102 is in threaded connection with the conical opening 101, so that the sampling rod 104 is completely retracted into the sampling tube 100, and simultaneously, after the sampling rod 104 is retracted, the plastic piston head 103 slides to be abutted with the limiting ring table 106, and the polygonal rod 107 completely extends out of the sampling tube 100;
In the initial state of the sampling bracket 110, as shown in fig. 2, since the mounting panel 116 of the link 112 is connected with the bar-shaped pad 111 through the spring rod 117, the spring rod 117 is in the maximum extension state, so that the link 112 is at the maximum distance above the bar-shaped pad 111;
Before the device is used, the sampling tube 100 needs to be connected with the sampling bracket 110, which specifically comprises the following steps:
Step ①: the jaw mechanism is loosened through the adjusting mechanism, one end of the L-shaped limiting plate 119 of the clamping assembly is pressed, the elastic force of the elastic hinging seat 118 is overcome, the other end of the L-shaped limiting plate 119 is turned away from the conical opening 101 of the sampling tube 100 corresponding to the elastic hinging seat 118, then the sampling tube 100 in an initial state is penetrated from the lower side of the through hole of the strip-shaped base plate 111, and in the penetrating process of the sampling tube 100, the sampling tube 100 is limited and can not rotate under the positioning cooperation of the positioning groove 115 of the sampling tube 100 and the positioning convex strip 114 of the boss 113 of the strip-shaped base plate 111;

when the device is used, the method comprises the following steps:
Step ①: medical staff supports the two ends of the strip-shaped base plate 111 on the two sides of the toilet bowl, pushes the connecting rod 112 downwards, overcomes the elastic force of the spring rod 117 and compresses the connecting rod, so that the polygonal rod 107 clamped and fixed by the jaw mechanism at the bottom of the connecting rod 112 moves downwards, thereby pushing the plastic piston head 103 to move downwards, and the sampling rod 104 extends out of the sampling tube 100, as shown in fig. 5, and the excrement in the toilet bowl is dipped by the metal bristles 105 on the side surface of the sampling rod 104 for sampling;
Step ②: after the feces is sampled, the spring rod 117 elastically returns to enable the claw mechanism to drive the polygonal rod 107, the plastic piston head 103 and the sampling rod 104 to return to the inside of the sampling tube 100 again, so that the sampled feces is collected into the sampling tube 100, and meanwhile, the bottom of the sampling tube 100 is provided with the conical opening 101, so that the feces sample cannot remain on the outer wall of the sampling tube 100 in the process of recovering the feces sampled by the sampling rod 104;
Step ③: medical staff re-uses the sealing cover 102 to seal the conical opening 101, and simultaneously seals the inside of the sampling tube 100 through the plastic piston head 103, so that feces and smell sampled in the sampling tube 100 cannot leak;
Step ④: medical staff releases the jaw mechanism again through the adjusting mechanism, so that the polygonal rod 107 of the sampling tube 100 is not clamped, and then releases the clamping assembly, so that the medical staff can take out the sampling tube 100 downwards from the through hole of the strip-shaped base plate 111.
