supplemented through the air holes 306, along with the fact that the magnetic block B305 is greatly pulled by the elastic rope 302, then a large amount of air on the top of the magnetic block B305 is supplemented through the air holes 306, the magnetic block B305 can be instantly pulled back by the elastic rope 302, at the moment, the magnetic block B305 rapidly slides and descends on the inner wall of the holding rod 2, finally, the magnetic block B305 descends and impacts the stop, at the moment, the sliding sleeve 301 is driven to synchronously descend instantly by the magnetic attraction of the magnetic block B305 and the magnetic block A303, the sliding sleeve 301 instantly pushes the long sliding sleeve 401 to rapidly fall through inertia through the elastic plate 402, at the moment, the elastic plate 402 is pulled to deform after the long sliding sleeve 401 falls, the long sliding sleeve 401 continuously falls to the magnetic plate A403 and the magnetic plate B404 inside through inertia to carry out the magnetic attraction, at the moment, the magnetic attraction force of the magnetic plate A403 and the magnetic plate B404 is greater than the elastic pull force of the elastic plate 402, so that the elastic plate 402 cannot pull the magnetic plate A403 and the magnetic plate B404 apart, the long sliding sleeve 401 is kept in a state of sliding and descending on the outer wall of the sliding sleeve 301, so that after excrement is sampled, the sampling cotton 1 is automatically protected by the sliding sleeve 301 and then automatically pushed out by the long sliding sleeve 401, the sampling cotton 1 is further shielded, the protection effect on the sampling cotton 1 is improved, the sampling cotton is automatically pushed out after sampling, the sampling cotton is kept on the outer wall of the sliding sleeve 301 before sampling, excessive space is not occupied, the carrying, transportation and use convenience are improved, the sampling cotton 1 is further protected, meanwhile, after the long sliding sleeve 401 is instantaneously pushed out along with inertia, the small elastic plate 406 in the long sliding sleeve 401 is popped out by the elastic force of the hinged plate 405, the sampling cotton 1 is fully wrapped by the hinged plate 405, and after the hinged plates 405 on the left side and the right side are popped out and tightly attached to each other, the sampling cotton 1 is sealed with the outside, and the sampling cotton 1 is prevented from being transported, because air oxidation and by the adhesion of external dust residue, and lead to the sample to receive the problem of pollution to appear, also further promoted the sample after the sample when carrying out the experiment accuracy, further guaranteed that the quality of sample is not influenced.
