When in use, the annular chassis 2 is first brought into contact with the limb so that the fixing ring 1 fits on the limb, and then the second circular ring 4 is brought into contact with the first circular ring 3, and the second circular ring 4 is rotated so that the second clamping block 7 moves along the side wall of the first clamping strip 8 and the first clamping block 6 moves along the side wall of the second clamping strip 9 and engages with each other, thereby allowing the sealing rings on the corresponding ends of the first circular ring 3 and the second circular ring 4 to fit tightly to avoid leakage during excretion. At the same time, the mutual engagement facilitates later replacement and disassembly.

[0026] A limiting mechanism for auxiliary fixing of the clamping mechanism is arranged at the top of the fixing ring 1 and on the outside of the clamping mechanism. The limiting mechanism includes a third ring 5 installed on the top of the fixing ring 1 and located on the outside of the first ring 3. The top of the third ring 5 is provided with openings 17 distributed at equal intervals around the circumference. Rectangular long blocks 18 are slidably connected to the inner side walls on both sides of the opening 17. The corresponding ends of the rectangular long blocks 18 are both in contact with the outer side wall of the second ring 4. A limiting rod 19 is fixedly installed on the top of the rectangular long block 18. A first ring gear 20 is also arranged above the top of the third ring 5 and on the outside of the second ring 4. The top of the first ring gear 20 is provided with a There are through-type oblique arc-shaped slots 22 distributed at equal intervals, one end of the limit rod 19 is slidably connected to the inner side of the oblique arc-shaped slot 22, the top of the fixed ring 1 is rotatably connected with a rotating rod 23, and a second ring gear 21 is fixedly installed on the outer surface of the rotating rod 23.

At the same time, the mutual engagement facilitates later replacement and disassembly.

[0030] At the same time, after the first circular ring 3 and the second circular ring 4 are fitted together, the rotating rod 23 is driven to rotate by turning the knob 25, and under the meshing characteristics of the gears, the second ring gear 21 is driven to drive the first ring gear 20 to rotate back and forth, so that the limiting rod 19 moves along the oblique arc-shaped notch 22, thereby driving the rectangular long block 18 to limit and fix the outer side of the second circular ring 4 to prevent the second circular ring 4 from shaking and separating from the first circular ring 3. While completing the auxiliary fixation of the excrement storage bag, it is only necessary to rotate the rotating rod 23 in the opposite direction to move the rectangular long block 18 away from the outer side of the second circular ring 4, and rotate to remove the second circular ring 4, so as to facilitate the replacement and cleaning of the excrement storage bag, improve the stability and flexibility of the use of the device, and increase the use efficiency.

[0031] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention.
