[0056] Example 1:

[0057] like Figures 1-3 As shown, the developing cartridge 1 includes a cartridge body 10, which stores developer. The cartridge body 10 has a first end 11 and a second end 12 disposed opposite to each other in a first direction, a third end 13 and a fourth end 14 disposed opposite to each other in a second direction, and a fifth end 15 and a sixth end disposed opposite to each other in a third direction. The developing cartridge 1 can be installed in an image forming apparatus for use.

[0058] like Figure 1 and Figure 2 As shown, a first cover 31 is provided at the first end 11. The first cover 31 is detachably fixedly installed on the cartridge body 10. The first cover 31 covers at least the transmission component portion located at the first end and is used to protect the transmission component and the first end 11. Multiple fasteners are provided on the developing cartridge 1 to tightly connect the components of the developing cartridge 1 together. The fasteners are preferably screws 101, and the first cover 31 is fastened to the cartridge body 10 by screws 101.

[0059] like Figure 1 and Figure 2 As shown, the transmission assembly includes a drive unit 40, which receives external power and is rotatable relative to the housing 10, with its rotation axis parallel to the first direction. The transmission assembly also includes a developing gear 41, a powder feeding gear 42, a stirring gear 43, and an idler gear 44, all of which rotate upon receiving power from the drive unit 40. This embodiment does not limit the number of gears in the transmission assembly; it can be set according to actual needs.

[0060] like Figure 1 and Figure 2 As shown, the developing cartridge 1 also includes a developing roller 131, a powder feeding roller (not shown), and a stirring frame (not shown), all three of which are rotatable and supported by the cartridge body 10. The developing roller 131 is located at the third end 13. The powder feeding roller delivers developer to the developing roller 131. The stirring frame is used to stir the developer to prevent it from clumping. The developing gear 41 drives the developing roller 131 to rotate, the powder feeding gear 42 drives the powder feeding roller to rotate, and the stirring gear 43 drives the stirring frame to rotate. In some embodiments, the powder feeding roller or the stirring frame may not be provided.

[0061] like Figure 1 As shown, a second cover 121 and an electrode 122 are provided at the second end 12. The second cover 121 is detachably installed on the housing 10 and is used to protect the second end 12. The electrode 122 is used to receive external electrical energy. The electrode 122 is electrically connected to the developing roller 131, or to the powder feeding roller, or to both the developing roller 131 and the powder feeding roller. The electrode 122 can be a steel sheet or other conductive materials such as conductive resin.

[0062] like Figure 2-Figure 3 As shown, a bracket cover 32 is also provided at the first end 11. The bracket cover 32 is first connected to the first cover 31 by a snap-fit, and then fastened to the first cover 31 by screws 109. A cavity is formed between the bracket cover 32 and the first cover 31.

[0063] like Figures 1-3As shown, the developing cartridge 1 also includes an identification component. In this embodiment, the identification component is preferably located at the first end 11, but it can also be located at the second end 12. The identification component includes a bracket 33 and a storage medium 34. The bracket 33 is located in the cavity formed by the bracket cover 32 and the first protective cover 31. The bracket 33 includes a first positioning post 331, a second positioning post 332, a receiving groove 333, a first hole 334, and a guide portion 335. The first positioning post 331 and the second positioning post 332 are preferably cylindrical protrusions extending in a first direction. The first positioning post 331 and the second positioning post 332 are respectively located on both sides of the bracket 33 in the first direction. A first positioning hole 331 is provided on the first cover 31, and the first positioning post 331 is inserted into the first positioning hole 331. In the radial direction perpendicular to the first direction, the size of the first positioning hole 311 is larger than the size of the first positioning post 331. A second positioning hole 321 is provided on the bracket cover 32, and the second positioning post 332 is inserted into the second positioning hole 321. In the radial direction, the size of the second positioning hole 321 is larger than the size of the second positioning post 332. That is, while the bracket 33 is supported by the first cover 31 and the bracket cover 32, it can move relative to the first cover 31 and the bracket cover 32. This embodiment does not limit the number of positioning holes and positioning posts.

[0064] like Figure 3 As shown, the receiving groove 333 is a recessed groove in the third direction. The storage medium 34 is installed in the receiving groove 333 along the third direction and is fastened to the receiving groove 333 by adhesive or double-sided tape. The adhesive force between the storage medium 34 and the receiving groove 333 makes it difficult for the storage medium 34 to detach from the receiving groove 333. The size of the storage medium 34 matches the size of the receiving groove 333. In some embodiments, it can also be installed on the receiving groove 333 by welding. The storage medium 34 can move relative to the housing 10 along with the bracket 33. The first hole 334 is a through hole that penetrates the bottom of the receiving groove 333 in the third direction. The first hole 334 is located below the storage medium 34.

[0065] like Figure 3 As shown, the guide portion 335 is arranged around the receiving groove 333 in the second direction. That is, the guide portion 335 is divided into two sections, one of which is located in front of the receiving groove 333 in the second direction, and the other end is located behind the receiving groove 333. The guide portion 335 extends in the first direction and is a sloped surface that is inclined relative to the first direction.

[0066] like Figure 3As shown, the storage medium 34 stores information of the developing cartridge 1. The upper surface of the storage medium 34 is provided with an electrical contact surface 341. The electrical contact surface 341 is used to directly contact the electrical contacts in the image forming apparatus to transfer the information in the storage medium 34 to the image forming apparatus. In this embodiment, the electrical contact surface 341 is preferably set to three, and the three electrical contact surfaces 341 are arranged along the first direction. The orientation (i.e., normal direction) of the electrical contact surface 341 is parallel to the third direction.

[0067] When assembling the developing cartridge 1, firstly, the first cover 31 is snapped onto the cartridge body 10 and secured with screws 101. Then, the bracket 33 containing the storage medium is connected to the first cover 331. Finally, the bracket cover 32 is snapped onto the first cover 31 and further secured with screws 109 to prevent the bracket cover 32 and the bracket 33 from detaching. To remove the storage medium 34 from the bracket 33, firstly, the screws securing the bracket cover 32 must be removed and the bracket cover 32 separated from the first cover 31. Then, the bracket 33 is removed from the first cover 31, and finally, the storage medium 34 is removed from the bracket 33.

[0068] This embodiment provides a disassembly fixture 50, which can remove the storage medium 34 from the bracket 33 without removing the bracket cover 32.

[0069] like Figures 4-8 As shown, the disassembly fixture 50 includes a first component 51 and a second component 52, which are movably connected. In this embodiment, a rotatable connection is preferred. The first component 51 supports the second component 52, and the second component 52 contacts the storage medium 4. The first component 51 includes a gripping part 511, a first connecting part 512, a receiving part 513, and a positioning part 516. The gripping part 511 allows the user to easily pick up the disassembly fixture 50. The first connecting part 512 consists of two opposing circular holes arranged in a second direction, located between the gripping part 511 and the positioning part 516 in the first direction. The receiving part 513 is hollow and is used to receive the second component 52. The positioning part 516 includes a positioning rib 514 and a positioning buckle 515. The positioning rib 514 is a rib extending in the first direction. Preferably, the two positioning ribs 514 are spaced apart in the second direction, with the spacing width matching the width of the bracket 33 in the second direction. The positioning buckle 515 is a snap-fit ​​protrusion located at the end of the first component 51 in the first direction. The positioning part 516 is also provided with a second hole 517, which is preferably a circular through hole that penetrates the positioning part 516 in a third direction.

[0070] like Figures 4-6As shown, the second component 52 includes a pressing part 521, a second connecting part 522, and a disassembly part 525. The second connecting part 522 consists of two cylindrical parts extending in a second direction. The second connecting part 522 is matched with the first connecting part 512 and is inserted into the first connecting part 512 so that the first component 51 and the second component 52 are rotatably connected with the connection point of the first connecting part 512 and the second connecting part 522 as a pivot center. The second component 52 is located within the receiving part 513 of the first component 51. In some embodiments, the shapes of the first connecting part 512 and the second connecting part 522 can be interchanged. The pressing part 521 is the end away from the developing cartridge 1. The user applies force to the pressing part 521 to make the second component 52 swing relative to the first component 51. In the first direction, the second connecting part 522 is located between the pressing part 521 and the disassembly part 525. In the third direction, the disassembly part 525 is located below the positioning part 516. The disassembly part 525 is provided with an abutment protrusion 523, which is preferably a cylindrical protrusion extending in the third direction, and the abutment protrusion 523 is aligned with the second hole 517 in the third direction.

[0071] like Figure 5 As shown, the disassembly fixture 50 also includes an elastic element 524, preferably a compression spring. The elastic element 524 can be compressed and extended in the third direction. One end of the elastic element 524 abuts against the lower surface of the positioning part 516, and the other end abuts against the upper surface of the disassembly part 525. In this embodiment, the elastic element 524 is preferably sleeved on the abutment protrusion 523 to prevent the elastic element 524 from falling off. When the pressing part 521 is subjected to a downward force, causing the second part 52 to rotate relative to the first part 51, the disassembly part 525 is lifted upward relative to the first part 51, the abutment protrusion 523 extends out through the second hole 517, and the elastic element 524 is compressed.

[0072] like Figure 4 , Figures 7-8As shown, when it is necessary to remove the storage medium 34 from the bracket 33, the user can position the disassembly fixture 50 on the bracket 33 along the first direction. Specifically, the positioning part 516 of the first component 51 is aligned with the upper end of the bracket 33 along the first direction, so that the positioning rib 514 continues to push the disassembly fixture 50 along the extension direction of the guide part 335 on the bracket 33. That is, the guide part 335 guides the disassembly fixture 50 to be connected and positioned on the bracket 33. When the disassembly fixture 50 moves to the point where the positioning buckle 515 is engaged with the end face of the bracket 333 facing the first cover 111 in the first direction, the positioning part 516 is completely positioned on the bracket 33, and the lower end face of the positioning part 516 abuts against the upper end face of the bracket cover 32, so that the bracket cover 32 provides support and limit for the disassembly fixture 50, thereby making the disassembly fixture 50 more stably positioned on the developing cartridge 1. At this time, with the first hole 334 and the second hole 517 aligned in the third direction, the abutment protrusion 523 does not contact the storage medium 34. In some embodiments, the positioning part 516 may be positioned on the first cover 31 or on the housing 10.

[0073] like Figure 8 As shown, when the user applies a downward force to the pressing part 521, the second component 52 pivots around the second connecting part 522 as the pivot center, the removal part 525 is lifted upward, and the abutment protrusion 523 enters the first hole 34 through the second hole 517. After the removal part 525 continues to rotate upward, the abutment protrusion 523 extends out of the first hole 334 and contacts the storage medium 34. The storage medium 334 is abutted by the abutment protrusion 523 and overcomes the adhesive force between the storage medium 34 and the receiving groove 333 (i.e., releases the connection between the storage medium 34 and the receiving groove 333) and moves upward relative to the receiving groove 333, thereby causing the storage medium 34 to detach from the bracket 33, or making the storage medium 34 no longer affected by the adhesive force and unable to be easily removed.

[0074] When the storage medium 34 is removed from the bracket 33 and the disassembly fixture 50 needs to be removed from the developing cartridge 1, the user releases the pressing part 521. The second part 52 rotates in the opposite direction under the elastic action of the elastic member 524 to reset, so that the abutment protrusion 523 exits the first hole 334, thereby making the disassembly fixture 50 easily removed from the developing cartridge 1.

[0075] In this embodiment, setting the distance between the pivot center of the second component 52 and the disassembly part 525 to be smaller than the distance between the pivot center and the pressing part 521 can save effort, making it easier for the user to use the disassembly tool 50.

[0076] In this embodiment, the disassembly tool 50 is a lever structure similar to nail clippers, which can help the user to easily remove the storage medium 34 from the bracket 33 without disassembling or damaging the bracket cover 32 and bracket 33 on the developing cartridge 1.

[0077] Example 2:

[0078] Unless otherwise specified, the structure of the developing cartridge 1 in this embodiment is the same as that in Embodiment 1. The difference between this embodiment and Embodiment 1 is that the structure of the support is different.

[0079] like Figure 9 and Figure 10 As shown, in this embodiment, the first cover of the developing cartridge 1 is provided with a first positioning hole 311 and a third positioning post 312. The first positioning hole 311 is preferably a round hole and there are two of them. The third positioning post 312 is preferably a cylinder extending in the first direction and there are two of them.

[0080] The bracket cover 32 includes a second positioning hole 321 and a third positioning hole 322, both of which are circular holes. Preferably, there are two third positioning holes 322. The third positioning post 312 is matched with the third positioning hole 322 and inserted into the third positioning hole 322 so that the bracket cover 32 is connected to the first cover 31, and the first cover 31 and the bracket cover 32 form a cavity.

[0081] like Figure 9 and Figure 10 As shown, the bracket 33 carries the storage medium 34. The bracket 33 includes a first positioning post 331 and a second positioning post 332. The first positioning post 331 is preferably a cylinder extending in a first direction and there are two of them. It is located on the side of the bracket 33 facing the first cover 31 in the first direction. The second positioning post 332 extends in the first direction and is located on the other side of the bracket 33 in the first direction.

[0082] like Figure 9 and Figure 10 As shown, the bracket 33 is located within the cavity. The first positioning post 331 is inserted into the first positioning hole 311, and the second positioning post 332 is inserted into the second positioning hole 321, so that the bracket is supported by the first cover 31 and the bracket cover 32. In the radial direction perpendicular to the first direction, the dimensions of the first positioning post 331 and the first positioning hole 311 are matched, preferably with an interference fit, and the dimensions of the second positioning post 332 inserted into the second positioning hole 321 are matched, preferably with an interference fit. That is, the bracket 33 is fixedly supported by the first cover 31 and the bracket cover 32 and cannot move relative to the housing 10, that is, the storage medium 34 cannot move relative to the housing 10.

[0083] Furthermore, the storage medium 34 can be displaced in a third direction by a height difference through the overall movement of the developing cartridge 1. The overall movement of the developing cartridge 1 can be caused by the developing cartridge 1 being abutted by the door cover of the image forming apparatus or by an elastic element being provided on the developing cartridge 1.

[0084] In some embodiments, the third positioning post 312 is preferably interference-fitted or snap-fitted with the third positioning hole 322, so that the bracket cover 32 and the first cover 31 are not fastened together by fasteners.

[0085] In other embodiments, fasteners such as screws may be used to further secure the bracket cover 32 and the first cover 31.

[0086] Example 3:

[0087] Unless otherwise specified, the structure of the developing cartridge 1 in this embodiment is the same as that in Embodiment 1. The difference between this embodiment and Embodiment 1 is that the structure of the disassembly fixture is different.

[0088] like Figure 11-14 As shown, the disassembly fixture includes a first component 61 and a second component 62. The first component 61 is a positioning component used to position the bracket 33 to prevent the bracket 33 from shaking during the removal of the storage medium 34. The second component 62 is used to remove the storage medium 34 from the bracket 33.

[0089] like Figure 11 As shown, the first component 61 has openings at its upper end in the third direction and its left end in the first direction, forming a semi-closed groove. The first component 61 includes a positioning portion 610 extending in the first direction and having height in the third direction. Preferably, two positioning portions 610 are provided, located on both sides of the first component 61 in the second direction, i.e., the positioning portions 610 are the side walls of the semi-closed groove structure. The second component 62 is provided with a disassembly portion 621, which is a blade-shaped part with a pointed tip. Preferably, two disassembly portions 621 are provided to prevent damage to one disassembly portion 621 from leaving the other as a spare. To facilitate the production and use of the second component 62, in this embodiment, the second component 62 is preferably tweezers-shaped, with the disassembly portion 621 located at the ends of the two arms of the tweezers. In some embodiments, the second component 62 can be other shapes such as a rod, with only one disassembly portion 621.

[0090] The following are the steps for removing the storage medium 34 from the bracket 33:

[0091] The first step is positioning. First, the bracket 33 is raised relative to the bracket cover 32. Then, the first component 61 is placed between the upper end of the bracket cover 32 and the lower end of the bracket 33 along the first direction. The upper end of the positioning part 610 contacts the lower end of the bracket 33, and the lower end of the positioning part 610 contacts the upper end of the bracket cover 32. The first component 61 is supported by the bracket cover 32 and supports the bracket 33. The first component 61 positions the bracket 33 to prevent the bracket 33 from moving relative to the bracket cover 32, thereby increasing the difficulty of removing the storage medium 34.

[0092] The second step is disassembly, which involves inserting the disassembly part 621 of the second component into the gap between the storage medium 34 and the receiving groove 333 that contains the storage medium 34. Then, using the contact point between the disassembly part 621 and the receiving groove 333 as a fulcrum, the storage medium 34 is pried out of the receiving groove 333 by prying, thereby removing the storage medium 34 from the bracket 33.

[0093] Furthermore, if double-sided tape or other adhesive 340 is attached to one end face of the storage medium 34, the storage medium 34 is fixed to the bracket 33 by adhesive. When the storage medium 34 is removed from the bracket 33, the adhesive 340 on the storage medium 34 can be removed by the removal part 621, either by clamping or by scraping.

[0094] Example 4:

[0095] Unless otherwise specified, the structure of the developing cartridge 1 in this embodiment is the same as that in Embodiment 3. The difference between this embodiment and Embodiment 3 is that the structure of the disassembly fixture is different.

[0096] like Figures 15-18 As shown, the disassembly fixture includes a first component 61, a second component 63, and a third component 64. In this embodiment, the first component 61, in addition to the positioning part 610, also includes a second hole 611 and a third hole 612. The second hole 611 and the third hole 612 are connected. The second hole 611 extends in a third direction and has openings at both ends in the third direction. The second hole 611 is preferably a circular hole. The third hole 612 extends in a first direction and has openings at both ends in the first direction, that is, the lower end of the second hole 611 in the third direction and the left end of the third hole 612 in the first direction are connected. A first guide groove 6111 extending in the third direction is provided on the hole wall of the second hole 611, and the third hole 612 includes a second guide groove 6121 extending in the first direction.

[0097] like Figure 16As shown, the second component 63 is movably connected to the first component 61. The second component 63 is located within the second hole 611. The second component 63 is used to move the storage medium 34 relative to the support 33 to remove the storage medium 34. The second component 63 is generally cylindrical and fits into the second hole 611. The second component 63 includes a first guided protrusion 631 and an abutting protrusion 632. The first guided protrusion 631 protrudes radially outward relative to the second component 63 and extends in the third direction. The first guided protrusion 631 is configured to cooperate with a first guide groove 611, which guides the second component 63 to move in the third direction. The abutting protrusion 632 is the upper end of the second component 63 in the third direction, preferably a pointed protrusion. The abutting protrusion 632 contacts the storage medium 34 to move the storage medium 34 relative to the support 33.

[0098] like Figure 16 As shown, the third component 64 is movably connected to the first component 61. The third component 64 has a shape adapted to fit the third hole 612, and at least partially slides within the third hole 612. The third component 64 drives the movement of the second component 63. The third component 64 includes a second guided protrusion 641 and an abutment portion 642. The second guided protrusion 641 protrudes radially relative to the third component 64 and extends in a first direction. The second guided protrusion 642 is configured to cooperate with a second guide groove 6121, which guides the movement of the third component 64 in the first direction. The abutment portion 642 is the left end of the third component 64. The abutment portion 642 is further a ramp inclined relative to both the first and third directions, extending to the left in the first direction while extending upward and downward in the third direction. The abutment portion 642 abuts against the lower end of the second component 63, causing the second component 63 to move upward in the third direction. In another embodiment, the inclined surface may be provided on the second component 63, or both the second component 63 and the third component 64 may have inclined surfaces, including arc surfaces and curved surfaces.

[0099] In this embodiment, the second component 63 and the third component 64 can be movably mounted on the first component 61 by means of a limiting structure such as a snap fastener, or they can be movably connected to the first component 61 through the second hole 611 and the third hole 612 when in use.

[0100] like Figures 17-18 As shown, the following are the steps for removing the storage medium 34 from the bracket 33:

[0101] First, raise the bracket 33 relative to the bracket cover 32, then place the first component 61 between the upper end of the bracket cover 32 and the lower end of the bracket 33 along the first direction. The first component 61 is supported by the bracket cover 32 and supports the bracket 33, positioning the bracket 33 to prevent it from shaking. After the first component 61 is installed in place, the abutting protrusion 632 of the second component 63 located in the second hole 611 aligns with the first hole 334.

[0102] The second step is to push the third component 63 to move to the left in the first direction, so that the abutment part 642 contacts the lower end of the second component 63. During the process of the third component 63 moving to the left in the first direction, the third component 63 pushes the second component 63 to move upward in the third direction through the abutment part 642 (i.e., the inclined surface). The abutment protrusion 632 contacts the storage medium 34 through the first hole 334. The storage medium 334 is abutted by the abutment protrusion 632 and overcomes the adhesive force between the storage medium 34 and the receiving groove 333, and moves upward relative to the receiving groove 333. The storage medium 34 is separated from the support 33.

[0103] Example 5:

[0104] Unless otherwise specified, the structure of the developing cartridge 1 in this embodiment is the same as that in Embodiment 1. The difference between this embodiment and Embodiment 1 is that the structure of the disassembly fixture is different.

[0105] like Figures 19-23 As shown, in this embodiment, the disassembly fixture 70 includes a first component 71 and a second component 72, which are movably connected. The first component 71 is used to position the disassembly fixture 70 on the housing 10, and the second component 72 is used to detach the storage medium 34 from the bracket 33.

[0106] like Figure 20 and Figure 21As shown, the first component 71 includes a receiving portion 711, which has openings at its upper end in the third direction and at its left end in the first direction, forming a semi-closed groove. The dimensions of the receiving portion 711 match the external dimensions of the receiving groove 333 of the bracket 33. A guided rail 712 for positioning the first component 71 onto the housing 10 is provided inside the receiving portion 711, extending in the first direction. A second hole 713 is provided at the bottom of the receiving portion 711, which is a through hole extending in the third direction. When the first component 71 is positioned on the housing 20, the second hole 713 and the first hole 334 are aligned in the third direction. The bottom of the receiving portion 711 also includes a first connecting hole 714 and a second connecting hole 715. The first connecting hole 714 and the second connecting hole 715 are through holes extending upward in a third direction, preferably round holes. In the first direction, the first connecting hole 714 is located between the second hole 713 and the second connecting hole 715. The first connecting hole 714 and the second connecting hole 715 form a first mating portion for mating with the second component 72 to guide the movement of the second component 72. A positioning buckle 716 is also provided at the left end of the receiving portion 711 in the first direction. The right end of the first component 71 in the first direction also includes a handle 717, which facilitates the user to pick up and disassemble the tooling 70.

[0107] like Figure 21 As shown, the second component 72 includes an abutment protrusion 721, an elastic element 723, and a second mating portion. The abutment protrusion 721 extends in a third direction and is aligned with the second hole 713 in the third direction. The second mating portion includes a first post 722 and a second post 724, which cooperate with the first mating portion to guide the movement of the second component 72 in the third direction and can connect the second component 72 to the first component 71. The first post 722 and the second post 724 are preferably cylindrical extending in the third direction. The first post 722 serves as a connection and guide, and a wedge-shaped retaining buckle is provided at the upper end of the first post 722. The retaining buckle is elastically deformable, passes through the first connecting hole 714, and fastens to the first connecting hole 714 so that the second component 72 cannot be detached from the first component 71. The first post 722 can move in the third direction relative to the first connecting hole 714. The second post 724 serves as a guide, can pass through the second connecting hole 715, and can move in the third direction relative to the second connecting hole 715. That is, the second component 72 can move relative to the first component 71 in a third-direction upward direction, but cannot detach from the first component 71. In the first direction, the first post 724 is located between the abutment protrusion 721 and the second post 724. In this embodiment, the first post 722 and the second post 724 are arranged on the left and right sides to ensure that the second component 72 can move stably relative to the first component 71. In other embodiments, only the first post 722 can be provided. The elastic element 723 is sleeved on the first post 722 and can be compressed and extended in a third-direction upward direction. The elastic element 723 is preferably a compression spring.

[0108] like Figures 22-23 As shown, the following are the steps for removing the storage medium 34 from the bracket 33:

[0109] In the first step, the disassembly fixture 70 is installed on the developing cartridge 1 along the first direction. The guide rail 712 of the first component 70 is guided by the outside of the receiving groove 333 of the bracket 33, so that the receiving part 711 is supported by the upper end of the bracket 33, and the positioning buckle 716 is fastened to the upper end of the bracket 33 to further achieve positioning.

[0110] The second step is to press down on the first component 71 and lift the second component 72 upward relative to the first component 71 in a third direction. The elastic element 723 is compressed, and the abutment protrusion 721 passes through the second hole 713 and the first hole 334 to contact the storage medium 34 and drive the storage medium 34 to move relative to the support 33, so that the storage medium 34 is disengaged from the support 33.

[0111] When removing the disassembly fixture 70 from the developing cartridge 1, simply loosen the second component 72. The second component 72 falls under the elastic action of the elastic member 723, and the disassembly fixture 70 is removed from the developing cartridge 1 by moving to the right in the first direction.

[0112] In another embodiment, the first component 71 may be subjected to force, causing the bracket 33 to move upward and downward in a third direction, so that the storage medium 34 approaches the abutment protrusion 721 and abuts.

[0113] Example 6:

[0114] Unless otherwise specified, the structure of the developing cartridge 1 in this embodiment is the same as that in Embodiment 5. The difference between this embodiment and Embodiment 5 is that the structure of the disassembly fixture is different.

[0115] like Figures 24-27 As shown, in this embodiment, the first component 73 and the second component 74 are movably connected. The first component 73 includes a receiving portion 731, the upper end of which is closed, and the left end of which is open to facilitate mounting the first component 73 onto the developing cartridge 1. The first component 73 is provided with a first mating portion, which is a connecting pawl 732 extending downward from the bottom end of the first component 73. The second component 74 is provided with a second mating portion, which is a connecting hole 742. The connecting pawl 732 and the connecting hole 742 engage to allow the first component 73 and the second component 74 to be movably connected. The second component 74 can move relative to the first component 73 in a third-order upward direction. An elastic member 744 is provided between the first component 73 and the second component 74, which can be compressed and extended in a third-order upward direction. The second component 74 also includes an abutment protrusion 741 extending in a third-order upward direction.

[0116] like Figures 26-27 As shown, the following are the steps for removing the storage medium 34 from the bracket 33:

[0117] The first step is to install the disassembly fixture onto the developing cartridge 1, and then place the developing cartridge 1 and the disassembly fixture upside down.

[0118] The second step involves pressing down on the first component 73 and applying force to the second component 74. The abutment protrusion 741 abuts against the storage medium 34 through the first hole 334, causing the storage medium 34 to detach from the bracket 33 and fall into the receiving portion 731 of the first component 73. In this embodiment, the first component 71 also serves to receive the storage medium 34 to prevent it from falling to the ground and being contaminated, damaged, or lost.

[0119] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
