The transmission ratio between the second gear 8 and the disc 9 is 1 to 6.

More specifically, when the fixing seat 1 is placed at a proper position of a sickbed, the motor II 5 is turned on to drive the threaded rod II 2 to start rotating, the height of the sampling plate 10 is adjusted to a height at which the anus of an elderly patient can be just inserted, the motor I6 is turned on, the rotation of the motor I6 drives the rotation shaft I14 to start rotating, the rotation of the rotation shaft I14 also drives the rotation shaft II 13 to start rotating under the action of the bevel gear transmission mechanism 7, and the rotation of the rotation shaft II 13 drives the gear I21 to start rotating.

As shown in fig. 1 and fig. 4, the rotation of the first gear 21 drives the rack bar 23 to move downwards, along with the downward movement of the rack bar 23, when the first fixing post 27 on the surface of the rack bar 23 contacts with the second fixing post 20 on the surface of the fixing frame 3, the rack bar 23 cannot continue to move downwards, the first gear 21 just finishes meshing with the rack bar 23 and starts to mesh with the first tooth 28 on the surface of the second moving block 25, and drives the first tooth 28 to move downwards, meanwhile, the spring 26 is compressed, and along with the continued rotation of the first gear 21, when the first gear 21 is disengaged from the first tooth 28, the second moving block 25 moves upwards to reset with the first tooth 28 under the action of the elastic potential energy of the spring 26, and at the moment, the first gear 21 meshes with the first tooth 28 again and drives the first tooth 28 to move downwards with the second moving block 25 again, namely, the rotation of the first gear 21 drives the second tooth 25 to reciprocate in the vertical direction with the first tooth 28.

The reciprocating movement of the second moving block 25 drives the rack row 23 and the third moving block 31 to reciprocate, when the third moving block 31 moves downward, the ring 34 is driven to move downward, and because the ring 34 is hinged to the sampling plate 10 through the hinge rod 32, the downward movement of the ring 34 drives the sampling plate 10 to move in a direction away from the axis of the disc 9, and meanwhile, the fourth moving block 36 also slides in a sliding groove on the surface of the disc 9 in a direction away from the disc 9, and the movement of the sampling plate 10 causes the four sampling plates 10 to open.

Similarly, when the moving block III 31 moves upwards to drive the ring 34 to move upwards, under the hinging action of the hinging rod 32, the upward movement of the ring 34 drives the sampling plates 10 to move towards the direction close to the axis of the disc 9, so that the four sampling plates 10 are closed again, and at this time, under the action of the end part cutting-off piece 11 of the sampling plate 10, the excrement in the aged can be cut off and collected between the two separating plates 33.

It should be noted that, since the sleeve 16 is sleeved on the outer side of the first rotating shaft 14 and the arc-shaped protrusion 15, the rotation of the first rotating shaft 14 drives the sleeve 16 to start rotating, the rotation of the sleeve 16 starts rotating the second gear 8, and when the disc 9 moves downward, the second gear 8 is driven to move downward synchronously under the action of the second connecting plate 17.

The rotation of the second gear 8 drives the disk 9 meshed with the second gear to start rotating, and the disk 9 slowly rotates under the rotation of the first rotating shaft 14 due to the fact that the transmission ratio between the second gear 8 and the disk 9 is large, so that the sampling collecting plate 10 can rotate in the anus of the old and sample the feces pathology samples simultaneously, the feces pathology samples are more uniform, sampling at the same position in the anus of the old is avoided, the single feces sampling device is single, and errors can be caused during subsequent feces pathology analysis.

As shown in fig. 1 and fig. 4, the rotation of the first gear 21 drives the rack bar 23 to move downward, at this time, two sliding blocks 30 on the side surface of the rack bar 23 also slide in the notch 29 on the inner wall of the fixed frame 3, and under the limiting effect of the notch 29, the rack bar 23 can be prevented from being separated from the fixed frame 3 when moving downward.

With the downward movement of the rack bar 23, when the first fixing post 27 on the surface of the rack bar 23 contacts with the second fixing post 20 on the surface of the fixing frame 3, the first gear 21 just engages with the rack bar 23, and simultaneously engages with the first tooth 28 on the surface of the second moving block 25, so as to drive the first tooth 28 to move downward, and the spring 26 is compressed, and with the continued rotation of the first gear 21, when the first gear 21 is disengaged from the first tooth 28, under the action of the elastic potential energy of the spring 26, the second moving block 25 moves upward to reset with the first tooth 28, and at the moment, the first gear 21 engages with the first tooth 28 again and drives the first tooth 28 to move downward with the second moving block 25 again, i.e. at the moment, the rotation of the first gear 21 drives the second moving block 25 to reciprocate vertically with the first tooth 28.

The reciprocating movement of the second moving block 25 drives the rack row 23 and the third moving block 31 to reciprocate, when the third moving block 31 moves downwards, the ring 34 is driven to move downwards, and the ring 34 is hinged with the sampling plate 10 through the hinge rod 32, at this time, the ring 34 moves downwards to drive the sampling plate 10 to move in a direction away from the axis of the disc 9, and meanwhile, the fourth moving block 36 also slides in a sliding groove on the surface of the disc 9 in a direction away from the disc 9, and the movement of the sampling plate 10 enables the four sampling plates 10 to be opened.

Similarly, when the moving block III 31 moves upwards to drive the ring 34 to move upwards, under the hinging action of the hinging rod 32, the sampling plate 10 moves towards the direction close to the axis of the disc 9, so that the four sampling plates 10 are closed again, at this time, under the action of the end cutting piece 11 of the sampling plate 10, the excrement in the aged can be cut off and collected between the two separating plates 33, so as to sample the pathological sample of the excrement.

The rotation of the first rotating shaft 14 can also drive the second gear 8 to start rotating, and the rotation of the second gear 8 can drive the disk 9 meshed with the second gear to start rotating, so that the sampling plate 10 can rotate in the anus of the old people and sample the anus, sampling is avoided at the same position in the anus of the old people, the single device is present, and the problem of error in subsequent fecal pathological analysis can be caused.

And along with the continuous rotation of the first motor 6, the four sampling and collecting plates 10 can continuously reciprocate, so that sustainable sampling is performed, after the sampling is finished, the first motor 6 is reversed, the rack bar 23 and the sampling and collecting plates 10 are driven to reset, and the device can be reset.
