Description

Technical Field

[0001] This application relates to the field of compression molding technology, and more specifically, to a processing apparatus. Background Technology

[0002] A baffle ring is used at the connection between a food waste separator / disposer and the kitchen sink drain. Its main function is to seal and separate wet and dry food waste, while also providing some sound insulation. Existing baffle rings feature a central opening and multiple folded sections. When food waste or a large flow of water passes through, the folded sections are pressed downwards, creating a larger channel and reducing the accumulation of waste at the baffle ring.

[0003] In related technologies, such as Chinese patent document CN214872045U, a molding die for a nitrile retaining ring used in a kitchen waste pulverizer is provided. This die discloses an upper die and a lower die. The upper die includes several downwardly protruding upper die protrusions, and when the upper and lower die are closed, a cavity for the retaining ring is formed between the upper die protrusions and the lower die groove. The upper die protrusion includes several upper inserts discretely arranged in the circumferential direction, and the upper die protrusion forms several upper insert grooves disposed between the upper inserts. The lower die forms several downwardly recessed lower die grooves. The upper die protrusion also includes a central portion, and the lower die groove has a central groove, forming a channel between the central groove and the central portion without a cavity. However, the retaining ring formed according to this die relies mainly on the folded portion of the retaining ring for its resilience. After long-term use, due to rubber aging, the retaining ring does not easily return to its original position. Summary of the Invention

[0004] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0005] Some embodiments of this application propose a processing apparatus to solve the technical problems mentioned in the background section above.

[0006] As a first aspect of this application, some embodiments of this application provide a processing apparatus suitable for processing retaining rings of a food waste shredder.

[0007] The processing apparatus includes: a mold for compression molding and vulcanizing the retaining ring, the retaining ring having a central hole; and a fixture for guiding a cutting element to process a cut at the end of a first side of the retaining ring, the cut being disposed of in the wall of the central hole and extending in the direction of the central hole.

[0008] The fixture includes: a support member having a plurality of support blocks having a second side that supports the retaining ring opposite to the first side; and a center member having a slot at least partially located between the two support members and having an inner tool setting groove between the two support blocks.

[0009] Furthermore, the mold includes: an upper mold having a plurality of downwardly protruding upper mold protrusions; and a lower mold having a plurality of downwardly recessed lower mold grooves; the upper mold protrusions include: a central portion for forming the inner wall of the cavity constituting the central hole of the retaining ring.

[0010] The lower mold groove is provided with a central groove for forming the outer wall of the cavity constituting the central hole of the retaining ring; wherein, the upper mold protrusion includes a plurality of upper inserts discretely arranged in the circumferential direction, and the upper mold protrusion forms a plurality of upper insert grooves disposed between the upper inserts; wherein, the lower mold groove includes a plurality of lower inserts discretely arranged in the circumferential direction and the lower mold groove forms a plurality of lower insert grooves disposed between the lower inserts so that the retaining ring can cover the inner groove opening when installed to the support member.

[0011] The central portion extends to the upper insert portion; the central groove communicates with the lower insert groove; the central groove corresponds to the position of the central portion and the outer edge of the central portion is located inside the groove wall of the central groove so that the cavity forms at least a portion of an annular space; the support member of the fixture is rotatably connected to the central member so that the cutting member can correspond to different circumferential positions of the retaining ring.

[0012] Furthermore, the inner tool groove is formed with an upper groove extending in the direction of the central hole.

[0013] Furthermore, the inner die groove has an inner groove extending in a direction perpendicular to the central hole; wherein, the upper die protrusion and the lower die groove are correspondingly arranged to form the cavity of the retaining ring between the upper die protrusion and the lower die groove when the upper die and the lower die are closed.

[0014] Furthermore, the support block also includes: a support plane, which is configured as at least a portion of a plane extending parallel to the direction of the central hole and intersects the opposing support planes of adjacent support blocks after extension; and a support ramp, which is configured as at least a portion of a conical surface having a cone.

[0015] The upper insert further includes: an upper outer inclined surface, configured as at least a portion of a conical surface having a cone; and an upper straight surface, configured as at least a portion of a plane containing the generatrix of a cone.

[0016] The lower insert includes: a lower straight surface configured to have at least a portion of the plane containing the generatrix of a cone and parallel to the upper straight surface; and a lower top surface configured to be a connecting surface connecting the two lower straight surfaces of the same lower insert.

[0017] Furthermore, the fixture also includes a limiting member configured to have two opposing limiting planes and the limiting planes correspond to the position of the supporting plane of the adjacent supporting block.

[0018] Furthermore, the central portion includes a protrusion perpendicular to the central axis, and the lower portion forms a groove that mates with the protrusion; or the lower portion includes a protrusion perpendicular to the central axis, and the central portion forms a groove that mates with the protrusion.

[0019] The limiting member further includes: an outer tool groove, configured to have a limiting groove that at least partially extends through the direction of the central hole and has an opening direction opposite to the inner groove.

[0020] Furthermore, the inner tool groove forms an inner limiting plane that is at least partially in the direction parallel to the extension of the central hole; the outer tool groove forms an outer limiting plane that is at least partially in the direction parallel to the extension of the central hole; wherein the inner limiting plane is parallel to or overlaps with the outer limiting plane.

[0021] Furthermore, the inner limiting plane is located within the outer tool setting groove.

[0022] Furthermore, the fixture further includes a fixing member movably connected to the limiting member; wherein the limiting member is configured to move relative to the fixing member on a plane perpendicular to the direction extending along the central hole and on a straight line intersecting the fixing member at the center.

[0023] The beneficial effect of this application is that it provides a processing device for improving the stability of the retaining ring during cutting.

[0024] More specifically, some embodiments of this application may produce the following specific beneficial effects:

[0025] The center hole is formed by the mold. When the fixture is cutting, the support member provides support to the retaining ring in the direction extending along the center hole, and the center member provides support to the center part in the direction perpendicular to the center hole. When the retaining ring is cut from the inner groove of the center member using the cutting member, the impact of the retaining ring movement on the retaining ring is reduced.

[0026] The limiting member is constructed with two opposing limiting planes and the limiting planes correspond to the supporting planes of the adjacent supporting blocks. The limiting member and the supporting blocks provide support on both sides of the supporting planes, reducing the deformation of the retaining ring caused by the restriction of the supporting blocks during the cutting process, thereby improving the shearing effect.

[0027] The center of the upper mold and the lower insert of the lower mold form a through hole. The support member of the fixture is rotatably connected to the center member so that the cutting member can correspond to different circumferential positions of the retaining ring. During cutting, due to the action of the cutting member, the position of the retaining ring relative to the center member will move, resulting in uneven cutting or the end point of the cut not being at the through hole. After cutting, the retaining ring is prone to tearing after use. Therefore, the fixture is also equipped with a limiting member. The cutting member forms an effective working space when cutting the retaining ring. In addition, the center member and the limiting member are respectively provided with inner and outer tool setting grooves. The corresponding inner and outer limiting planes serve as supports, thereby ensuring that the cutting direction is along the direction extending from the center hole. Attached Figure Description

[0050] Embodiments of this disclosure will now be described in more detail with reference to the accompanying drawings. While some embodiments of this disclosure are shown in the drawings, it should be understood that this disclosure can be implemented in various forms and should not be construed as limited to the embodiments set forth herein.

[0052] It should be noted that the concepts of "first" and "second" mentioned in this disclosure are used only to distinguish different devices, modules or units, and are not used to limit the order of functions performed by these devices, modules or units or their interdependencies.

[0053] It should be noted that the terms "a" and "a plurality of" used in this disclosure are illustrative rather than restrictive, and those skilled in the art should understand that, unless otherwise expressly indicated in the context, they should be understood as "one or more".

[0054] The names of messages or information exchanged between multiple devices in the embodiments of this disclosure are for illustrative purposes only and are not intended to limit the scope of such messages or information.

[0055] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0056] like Figure 1 The diagram shows the structure of the retaining ring 100 formed after using the mold.

[0057] The 100 retaining ring is used at the connection point between the food waste separator / shredder and the kitchen sink drain.

[0058] The retaining ring 100 includes a folded portion 110. The folded portion 110 defines a plurality of corresponding top surfaces 120, a vertical surface 130 near the central hole 150, and a slit 613 formed by cutting with the jig 700 of this application.

[0059] When food waste or water enters the finished baffle ring 600 after cutting, it is pushed downwards on the folded top surface 612. The flat top surface 612 helps to minimize the resistance of the folds to deflection and bending under load, making it easier for food waste or water to pass through the finished baffle ring 600. When the top surface 612 is pressed down, the slit 613 opens to accommodate a faster flow of water or food waste.

[0060] The retaining ring 100 formed using the mold of this application does not yet have a slit 613. The slit 613 is located on the vertical surface 612. Because the slit 613 is small, an additional jig 700 is required to cut it, thereby forming a larger opening when food waste and water pass through.

[0061] like Figure 4 As shown, the mold in one embodiment of this application mainly includes an upper mold 300 and a lower mold 400.

[0062] Among them, such as Figure 8 and Figure 9 As shown, the upper mold 300 includes several downwardly protruding upper mold protrusions 310.

[0063] like Figure 10 and Figure 11 As shown, the lower mold 400 has several downwardly recessed lower mold grooves 410.

[0064] Specifically, such as Figure 5 and Figure 9As shown, the upper mold protrusion 310 includes an upper insert portion 3110 and a central portion 3130, and forms an upper insert groove 3120.

[0065] The upper mold protrusion 310 includes a plurality of upper inserts 3110 discretely arranged in the circumferential direction. The upper mold protrusion 310 forms a plurality of upper insert grooves 3120 disposed between the upper inserts 3110. The central part 3130 is used to form the inner wall of the cavity 180 that constitutes the central hole 150 of the retaining ring 100.

[0066] like Figure 11 As shown, the lower mold groove 410 includes a lower insert 4110, forming a lower insert groove 4120 and a central groove 4130.

[0067] The lower mold groove 410 includes a plurality of lower inserts 4110 discretely arranged in the circumferential direction. The lower mold groove 410 forms a plurality of lower insert grooves 4120 disposed between the lower inserts 4110. The central groove 4130 is used to form the outer wall of the cavity 180 that constitutes the central hole 150 of the retaining ring 100.

[0068] As a specific solution, such as Figure 4 and Figure 5 As shown, the upper mold protrusion 310 and the lower mold groove 410 are correspondingly arranged to form a cavity 180 of the retaining ring 100 between the upper mold protrusion 310 and the lower mold groove 410 when the upper mold 300 and the lower mold 400 are closed; the lower mold groove 410 includes a plurality of lower inserts 4110 discretely arranged in the circumferential direction, and the lower mold groove 410 forms a plurality of lower insert slots 4120 disposed between the lower inserts 4110.

[0069] The central portion 3130 extends to the upper insert portion 3110. The central portion 3130 extends along the central axis and is a rotating body about the central axis. The central groove 4130 is connected to the lower insert groove 4120.

[0070] It should be noted that the cone rotates around its central axis.

[0071] The state after the upper mold 300 and the lower mold 400 are closed is as follows Figure 5 As shown.

[0072] The central groove 4130 corresponds to the central portion 3130, and the outer edge of the central portion 3130 is located inside the groove wall of the central groove 4130, so that the cavity 180 forms at least a portion of an annular space, such as Figure 7 As shown.

[0073] If the central groove 4130 corresponds to the central portion 3130 and the outer edge of the central portion 3130 is located outside the groove wall of the central groove 4130 or they are flush, meaning the thickness of the cavity 180 at this location is the same as at other locations, the thickness of the retaining ring 100 produced will also be the same. The resulting retaining ring 100 will be prone to breakage at the locations of the central portion 3130 and the central groove 4130, thus requiring reinforcement. In practice, the size of the cavity 180 at the relative positions of the central groove 4130 and the central portion 3130 can be increased, but the thickness of the resulting retaining ring 100 will change, thus affecting the resilience of the retaining ring 100. By having the central groove 4130 and the central portion 3130 correspond and the outer edge of the central portion 3130 is located inside the groove wall of the central groove 4130, the cavity 180 forms at least a portion of an annular space.

[0074] In this way, the strength of the folded portion 110 of the retaining ring 100 at the position corresponding to the center ring of the mold is higher than that of other positions in the cavity 180, which improves the service life of the folded portion 110 of the retaining ring 100 and avoids the retaining ring 100 from being easily deformed or torn due to the thickening of the center groove 4130 and the center portion 3130.

[0075] The central portion 3130 includes a protrusion 3131 perpendicular to the central axis, and the lower portion 4110 forms a groove 4113 that mates with the protrusion 3131; or, the lower portion 4110 includes a protrusion 3131 perpendicular to the central axis, and the central portion 3130 forms a groove 4113 that mates with the protrusion 3131.

[0076] As a specific solution, such as Figure 9 As shown, the central portion 3130 includes a protrusion 3131 perpendicular to the central axis, such as... Figure 11 As shown, the lower insert 4110 has a groove 4113 that mates with the protrusion 3131.

[0077] The central portion 3130 includes a protrusion 3131 perpendicular to the central axis, and the lower insert portion 4110 forms a groove 4113 that mates with the protrusion 3131; or the lower insert portion 4110 includes a protrusion 3131 perpendicular to the central axis, and the central portion 3130 forms a groove 4113 that mates with the protrusion 3131. The opposing protrusions 3131 or grooves 4113 ensure that during the molding and vulcanization process of the upper mold 300 and lower mold 400, the retaining ring 100 rubber blank will not, or only slightly, enter the positions corresponding to the protrusions 3131 and grooves 4113. After demolding, the through hole 190 can be formed without or with only simple processing, improving the molding efficiency and stability of the retaining ring 100 and avoiding a decrease in yield due to the need for multiple subsequent processing steps on the retaining ring 100.

[0078] When food waste and water pass through the baffle ring 100, both the top surface 120 and the vertical surface 130 of the baffle ring 100 are pressed down. Especially when the amount of food waste and water is large, it may block the entrance of the baffle ring 100, resulting in inconsistent pressure on the upper and lower surfaces of the baffle ring 100. Therefore, it is necessary to make an opening in the top surface 120 or the vertical surface 130 of the baffle ring 100. However, making an opening on the intact surface of the baffle ring 100 will inevitably increase the number of processing steps for the baffle ring 100, and the increased number of cuts will easily lead to tearing of the baffle ring 100.

[0079] Therefore, in mold design, on the one hand, the opening should be designed in the position where the deformation of the retaining ring 100 is relatively small when food waste and water pass through the top surface 611120 and the vertical surface 130 of the retaining ring 100. On the other hand, the shearing process should be reduced and the mold should be easy to form.

[0080] Based on this, more specifically, the upper insert 3110 includes an upper outer inclined surface 3111 and an upper side straight surface 3112, and an upper insert step 3121 is formed at the bottom of the upper insert groove 3120.

[0081] The upper outer inclined surface 3111 is constructed as at least a portion of a conical surface having a cone, and the upper straight surface 3112 is constructed as at least a portion of the plane containing the generatrix of a cone.

[0082] The upper step 3121 has two parallel upper step surfaces 3121a and an upper connecting surface 3121b connecting them. The upper step surfaces 3121a are perpendicular to the central axis, and the upper connecting surface 3121b is parallel to the central axis. The upper connecting surface 3121b is part of a cylindrical surface (a cylindrical surface with the central axis as its axis), and the upper step surfaces 3121a are fan-shaped surfaces.

[0083] like Figure 11 As shown, the lower insert 4110 includes a lower straight surface 4111 and a lower top surface 4112.

[0084] The lower straight surface 4111 is configured to have at least a portion of the plane containing the generatrix of a cone and is parallel to the upper straight surface 3112; the lower top surface 4112 is configured to be a connecting surface connecting the two lower straight surfaces 4111 of the same lower insert 4110.

[0085] The cutting edge forming the vent can be set on the upper outer bevel 3111, upper side straight surface 3112, lower side straight surface 4111, and lower top surface 4112. If the upper outer bevel 3111, upper side straight surface 3112, lower side straight surface 4111, and lower top surface 4112 form vent openings 170 of the retaining ring 100 on the corresponding cavity 180, when food waste or water flows through, the corresponding vent opening 170 will be blocked along with the food waste or water flow, thus affecting the ventilation effect.

[0086] Therefore, the ventilation opening 170 is set on the lower embedded step surface 4112a or the upper embedded connecting surface 3121b, that is, the cutting edge is set on the lower embedded step surface 4112a or the upper embedded connecting surface 3121b. This way, the shearing cutting edge can be formed when the upper mold 300 and the lower mold 400 are demolded, simplifying the shearing process.

[0087] As a specific solution, such as Figure 11 As shown, the lower top surface 4112 has a lower embedded step surface 4112a, and the lower embedded step surface 4112a has a lower embedded cutting edge 4112b that protrudes from the lower embedded step surface 4112a 3131. The lower embedded cutting edge 4112b is opposite to the upper embedded connecting surface 3121b. When the upper mold 300 and the lower mold 400 separate, the lower embedded cutting edge 4112b can cut the retaining ring 100, so that when the mold separates, a vent hole can be formed at the corresponding position of the lower embedded cutting edge 4112b, without the need to use a separate cutting tool.

[0088] It should be noted that each lower step surface 4112a may have a lower cutting edge 4112b, or a lower cutting edge 4112b may be present on some of the lower step surfaces 4112a.

[0089] Because of the ventilation opening 170 provided on the retaining ring 100, the stability of the lower top surface 4112 will be affected, so it is necessary to provide reinforcing ribs in the cavity 180.

[0090] The lower top surface 4112 has a through groove 4112c that passes through the same lower insert 4110.

[0091] like Figure 4 and Figure 5 As shown, the mold also includes: a middle mold 500, which contains at least one channel 510.

[0092] The channel 510 is configured to allow the upper mold 300 to pass through, and a cavity 180 is formed between the upper mold protrusion 310 and the lower mold groove 410 to form the outer wall of the retaining ring 100.

[0093] The channel 510 is formed with a channel wall 5110 that constitutes the outer wall of the retaining ring 100.

[0094] O-shaped tear ribs 530 are provided around the cavity 180 on the upper surface of the upper mold 300 and the middle mold 500, and O-shaped tear ribs 530 are provided around the lower surface of the middle mold 500 and the cavity 180 of the middle mold 500, so that the multiple retaining rings 100 formed after the retaining ring 100 rubber blank is molded by pressure vulcanization can be easily separated.

[0095] The middle mold 500 has an overflow groove 520 in a direction parallel to the central axis, which facilitates the overflow of excess glue into the overflow groove 520, thereby ensuring the flash thickness of the retaining ring 100.

[0096] Using the above-mentioned mold, the following is obtained: Figure 1 and Figure 2 The retaining ring 100 is shown.

[0097] The retaining ring 100 has a central hole 150, and a notch is provided on the wall of the central hole 150 and extends along the direction in which the central hole 150 extends. The direction of extension D of the central hole 150 is as follows: Figure 1 As shown.

[0098] When the retaining ring 100 needs to be cut, the cutting tool begins cutting from the end of the first side 140 of the retaining ring 100. Meanwhile, as... Figure 1 As shown, the second side 160 is opposite to the first side 140 of the retaining ring 100.

[0099] It should be noted that the cutting parts are not shown in the figure.

[0100] A schematic diagram of the structure of the retaining ring 600 formed by cutting the retaining ring 100 using the jig 700 of this application is shown below. Figure 3 As shown.

[0101] The finished baffle ring 600 is used at the connection point between the food waste separator / shredder and the kitchen sink drain.

[0102] The finished retaining ring 600 includes a folded portion 610. The folded portion 610 defines a plurality of corresponding top surfaces 611, a vertical surface 130 near the central hole, and a slit 613 cut by the jig 700 of this application. When food waste or water enters the central hole, it is pushed downward on the folded top surfaces 611. The flat top surfaces 611 help to minimize the resistance of the folds to deflection and bending under load, allowing water to pass through the retaining ring 100 more easily. When the top surfaces 611 are pressed down, the slit 613 opens to accommodate a faster flow of water or food waste.

[0103] like Figure 12 and Figure 13 As shown, a jig 700 of one embodiment of this application is used to guide a cutting member to process a cut at the end of a first side 140 of a retaining ring 100, and mainly includes: a support member 710 and a center member 720.

[0104] The support member 710 has a plurality of support blocks 711 on which the second side 160 is provided opposite to the first side 140 to support the retaining ring 100. The center member 720 is disposed between at least two support members 710 and has an inner tool setting groove 721 with a slot at least partially disposed between the two support blocks 711.

[0105] When the center hole 150 is formed by the mold and the fixture 700 is cutting, the support member 710 provides support to the retaining ring 100 in the direction extending along the center hole 150, and the center member 720 provides support to the center portion 3130 in the direction perpendicular to the extension of the center hole 150. When the retaining ring 100 is cut from the inner cutting groove 721 of the center member 720 using a cutting member, the impact on the retaining ring 100 caused by the movement of the retaining ring 100 is reduced.

[0106] When cutting is required, the retaining ring 100 is fitted onto the center piece 720, and the support block 711 supports the retaining ring 100.

[0107] As a specific solution, the support member 710 and the center member 720 can be integrally connected or rotatably connected. When the retaining ring 100 needs to cut a large number of slits 613, a rotatable connection is preferred to reduce the movement of the retaining ring 100.

[0108] like Figure 14 As shown, the inner tool setting groove 721 has an upper groove opening 721a extending in the direction of the central hole 150, and an inner groove opening 721b extending in the direction perpendicular to the central hole 150.

[0109] The upper groove 721a and the inner groove 721b allow the cutting part to enter the inner tool setting groove 721, thereby cutting the retaining ring 100. This avoids multiple cutting attempts due to space limitations, which would otherwise lead to a decrease in the yield rate.

[0110] like Figure 15 As shown, the support block 711 further includes a support plane 711a and a support ramp 711b. The support plane 711a is configured as at least a portion of a plane parallel to the direction of extension of the central hole 150, and the opposing support planes 711a of adjacent support blocks 711 intersect after extension; the support ramp 711b is configured as at least a portion of a conical surface having a cone shape.

[0111] Since the retaining ring 100 and the center member 720 are not in tight contact, if the position of the retaining ring 100 is not limited along the direction of the center hole 150, the retaining ring 100 will move up and down during cutting, resulting in cutting failure or unevenness of the slit 613. Therefore, the support member 710 also includes a support plane 711a and a support inclined plane 711b, which restricts displacement in the direction perpendicular to the direction of extension of the center hole 150. With the presence of the support plane 711a, a gap is left between two adjacent support blocks 711. During shearing, the cutting part not only has space inside the center hole 150 of the retaining ring 100, but also has space on the side of the retaining ring 100 opposite to the support block 711, further improving the yield of the retaining ring 100 cutting.

[0112] like Figure 12 , Figure 13 and Figure 16 As shown, the fixture 700 also includes a limiting member 730.

[0113] The center part 3130 of the upper mold 300 and the lower insert part 4110 of the lower mold 400 cooperate to form a through hole 190. The support member 710 of the fixture 700 is rotatably connected to the center member 720 so that the cutting member can correspond to different circumferential positions of the retaining ring 100. During cutting, due to the action of the cutting member, the position of the retaining ring 100 relative to the center member 720 will move, resulting in uneven cutting or the end point of the cut not being at the through hole 190. The finished retaining ring 600 is easy to tear after use. Therefore, the fixture 700 is also provided with a limiting member 730. When the cutting member cuts the retaining ring 100, it forms an effective working space for the cutting member.

[0114] The limiting member 730 is configured to have two limiting planes 731 arranged opposite to each other and the limiting planes 731 correspond to the position of the supporting plane 711a of the adjacent supporting block 711.

[0115] The support block 711 provides support on both sides of the support plane 711a, thereby reducing the deformation of the retaining ring 100 caused by the restriction of the support block 711 during the cutting process and improving the shearing effect.

[0116] The limiting member 730 also includes an outer tool setting groove 732. The outer tool setting groove 732 is configured to have a limiting groove that at least partially extends through the center hole 150 and whose opening direction is opposite to the inner groove opening 721b.

[0117] In this way, the center member 720 and the limiting member 730 are respectively provided with an inner tool setting groove 721 and an outer tool setting groove 732, and the corresponding inner limiting plane 721c and outer limiting plane 732a serve as supports, thereby ensuring that the cutting direction is along the direction extending along the center hole 150, thereby improving the stability of the cut of the cut retaining ring 100.

[0118] More specifically, the inner tool groove 721 has an inner limiting plane 721c that extends at least partially in the direction parallel to the center hole 150; the outer tool groove 732 has an outer limiting plane 732a that extends at least partially in the direction parallel to the center hole 150.

[0119] When the cutting part enters the inner tool setting groove 721 and the outer tool setting groove 732, it can be supported by the inner limiting plane 721c and the outer limiting plane 732a, thereby ensuring that the cutting direction is along the direction extending along the center hole 150.

[0120] The inner limiting plane 721c is parallel to or overlaps with the outer limiting plane 732a.

[0121] As a specific solution, the inner limiting plane 721c is located inside the outer tool setting groove 732.

[0122] In this way, the position of the cutting part is restricted between the inner limiting plane 721c and the outer limiting plane 732a, which improves the stability of the cutting position.

[0123] The fixture 700 also includes a fixing element. The fixing element is connected to the limiting element 730.

[0124] As a specific solution, the fixing component and the limiting component 730 are movably connected. The movable connection method can be snap-fit, rotational connection, etc.

[0125] The limiting member 730 is configured to move relative to the fixing member on a plane perpendicular to the direction extending along the central hole 150 and on a straight line intersecting the fixing member at the center 3130.

[0126] The fixing member can be fixedly connected to the center member 720, or both the fixing member and the center member 720 can be fixed to the same or different target objects, ensuring that the relative position of the fixing member and the center member 720 is constant. Through the movable connection between the fixing member and the limiting member 730, the limiting member 730 can be moved out from two adjacent support blocks 711 without restricting the rotation of the support members 710 to between two more support blocks 711, and then the limiting member 730 is placed between the support blocks 711 for the next slit 613 cutting. It should be noted that the fixing member is not shown in the figure.
