[0033] Referring to Figures 1 to 6 , the following embodiments are made for the stoma chassis cutting device of the present utility model:

[0034] A stoma chassis cutting device includes: a profiling member 10 and a cutting member 20.

[0035] The profiling member 10 and the cutting member 20 are arranged up and down.

[0036] The profiling member 10 has a central axis extending in the up and down direction. The profiling member 10 includes: a profiling sheet 200 and a limiting assembly 300. The profiling sheet 200 extends in a ring shape, and the central axis passes through the space surrounded by the profiling sheet 200. A plurality of the limiting assemblies 300 are circumferentially distributed around the central axis on the outer periphery of the profiling sheet 200. The limiting assembly 300 has an adjustable end 321 along the radial direction of the central axis. The adjustable end 321 is connected to the outer side of the profiling sheet 200.

[0037] The cutting member 20 is arranged up and down in alignment with the profiling member 10. The cutting member 20 includes: a positioning disk 400 and a cutting and pressing rod 500.

[0038] When actually using the cutting device of the present utility model to cut the stoma chassis: adjust the adjustable ends 321 of the plurality of limiting assemblies 300, and the adjustable ends 321 can drive the profiling sheet 200 to deform, so that the extension path of the profiling sheet 200 can be consistent with the stoma shape. Place the stoma chassis in the positioning groove 410 of the positioning disk 400 so that the stoma chassis can be aligned up and down with the profiling sheet 200. At this time, press the profiling member 10 against the stoma chassis, and by rotating the cutting and pressing portion 510 of the cutting and pressing rod 500, roll-press the stoma chassis, so that the profiling sheet 200 can cut and press the stoma shape on the stoma chassis, realizing the cutting process of the stoma chassis.

[0039] In this embodiment, the profiling piece 200 is a metal thin sheet product. For the convenience of cutting the stoma chassis, it is preferable that one end of the profiling piece 200 facing the cutting member 20 has a sharp edge. The profiling piece 200 has a first end 210 and a second end 220. The first end 210 and the second end 220 are respectively arranged at two circumferential ends of the profiling piece 200. One of the adjusting ends 321 is connected to the outside of the first end 210, and the second end 220 is placed on the inside of the first end 210. The inside of the profiling piece 200 refers to the side facing the central axis, and the outside of the profiling piece 200 refers to the other side.

[0040] The second end 220 of the profiling piece 200 is placed on the first end 210, and a closed-loop shape can be formed. When the two adjusting ends 321 connecting the first end 210 and the second end 220 approach each other, the overlapping area of the first end 210 and the second end 220 increases, and vice versa.

[0041] In this embodiment, a connecting groove 230 extending along the circumference is provided on the outside of the profiling piece 200. The adjusting end 321 is slidably clamped in the connecting groove 230.

[0042] In a further embodiment, to provide an installation support basis for a plurality of the limiting components 300, the profiling member 10 further includes a profiling substrate 100. The profiling substrate 100 is in the shape of an annular plate, and the central axis coaxially penetrates through the profiling substrate 100. The profiling piece 200 is arranged in the middle of the profiling substrate 100, and a plurality of the limiting components 300 are evenly distributed around the central axis on the profiling substrate 100.

[0043] The limiting component 300 includes: a base and an adjusting rod 320. The base is fixedly connected to the profiling substrate 100. The adjusting rod 320 is slidably connected to the base along the radial direction of the profiling substrate 100. The adjusting end 321 is arranged at one end of the adjusting rod 320 facing the central axis.

[0044] In this embodiment, the base has a sliding groove 310 extending along the radial direction of the profiling substrate 100, and the middle part of the adjusting rod 320 is slidably embedded in the sliding groove 310, so that the adjusting rod 320 is slidably connected to the base, and the position adjustment of the adjusting end 321 is realized through the relative sliding of the adjusting rod 320 and the base.

[0045] To position the adjusting rod 320 and the base, the base has a plurality of positioning slots arranged at equal intervals along the radial direction of the profiling substrate 100, and the adjusting rod 320 is elastically provided with positioning portions 322 corresponding to the positioning slots. Both the positioning slots and the positioning portions 322 extend in a direction perpendicular to the radial direction of the profiling substrate 100. In this embodiment, the positioning portion 322 is provided at one end of the adjusting rod 320 facing away from the central axis.

[0054] To make the rotation of the punching rod 500 smoother, a connecting ring is arranged on the lower side of the punching rod 500. The connecting ring is circular or disc-shaped. The punching rod 500 is fixedly connected to the connecting ring, and the connecting ring is rotatably embedded in the punching hole 420.

[0055] In some embodiments, the positioning disk 400 is provided with a rotation driving member. The rotation driving member is in transmission connection with the connecting ring of the punching rod 500. The inner side of the connecting ring is rotatably connected to the positioning disk 400, and a toothed ring is fixedly arranged on the outer side of the connecting ring. The rotation driving member is rotatably installed on the positioning disk 400, and the end of the rotation driving member has a driving gear that meshes with the toothed ring in transmission.

[0056] In some other embodiments, the rotation driving member and the punching rod 500 can also be in transmission connection through other means such as belt drive, chain drive, gear drive or worm and worm gear drive.

[0057] In some embodiments, the cutting member 20 and the profiling member 10 adopt a split structure. The positioning disk 400 is provided with a positioning column 110 extending upward, and the lower side of the profiling substrate 100 is provided with a positioning hole 430 corresponding to the positioning column 110. During the process of cutting the stoma chassis, the positioning column 110 is inserted into the positioning hole 430 to prevent relative displacement between the profiling member 10 and the cutting member 20.

[0058] Refer to the attached Figure 6 In some other embodiments, the cutting member 20 and the profiling member 10 can be flip-open and closed connected.
