Description

Technical Field

[0001] This invention relates to the field of disassembly and assembly, and in particular to a disassembly device. Background Technology

[0002] Snap rings, as commonly used axial positioning parts, are widely used in small machinery, precision instruments, and 3C consumer electronics products. In related technologies, the disassembly of snap rings often relies on simple tools. For example, operators need to use needle-nose pliers, screwdrivers, and other tools to pry open the snap ring opening. This is not only inconvenient and inefficient, but also causes the tools to come into direct contact with the product's surface, easily resulting in scratches. This makes it unsuitable for products with high appearance requirements and precise structures.

[0003] Taking a stylus in 3C consumer electronics as an example, the plug and clip at the end of the pen barrel are usually connected by a spring clip. After the plug and clip are assembled, if the clip needs to be disassembled due to quality inspection failure or function debugging, the existing disassembly method requires the use of tools to directly pry the spring clip. As the external parts of the stylus, the plug and clip may be scrapped due to irreparable damage caused by tools once scratched or bumped by tools, resulting in unnecessary waste of production costs. Summary of the Invention

[0004] Based on this, the present invention provides a disassembly device, comprising: A positioning element is used to position a first object. The first object is externally fitted with a first retaining spring that surrounds a first direction and has an opening. The first object has a cavity extending along the first direction and a through hole that penetrates the outer surface of the first object and the cavity and is correspondingly provided with the first retaining spring. The positioning element is inserted into the cavity. The positioning element has a first mounting hole extending along the first direction and a second mounting hole that is formed in the wall of the first mounting hole and coaxially communicates with the through hole. A first pusher, passing through the second mounting hole, has a first end facing the first retaining ring and a second end disposed opposite to the first end in the axial direction of the second mounting hole; and The second pusher is inserted into the first mounting hole and abuts against the second end of the first pusher. The second pusher can move in the positive direction along the first direction to push the first pusher through the through hole and push the first retaining spring away from the first object, thereby expanding the width of the opening.

[0005] Furthermore, the first pusher has a first inclined surface disposed at the second end of the first pusher, and the first inclined surface is inclined relative to the first direction; The second pusher has a second inclined surface that is disposed corresponding to the first inclined surface, and the second inclined surface is inclined relative to the first direction; During the forward movement of the second pusher along the first direction, the first inclined surface and the second inclined surface slide into contact.

[0006] Furthermore, the second inclined surface includes a first face and a second face arranged sequentially along the positive direction of the first direction. The angle between the first face and the first direction is equal to the angle between the first inclined surface and the first direction, and the angle between the second face and the first direction is greater than the angle between the first inclined surface and the first direction.

[0007] Furthermore, the disassembly device includes two first push members, which are symmetrically arranged about the opening of the first retaining ring, and the second push member is located between the two first push members.

[0008] Furthermore, the second pusher can move between a first position and a second position, the first position and the second position being sequentially arranged along the positive direction of the first direction; When the second pusher is in the first position, the second ends of the two first pushers abut against each other or have a first gap, and the width of the opening is a first width value; When the second pusher is in the second position, the second ends of the two first pushers have a second gap, and the width of the opening is a second width value, the second gap is greater than the first gap, and the second width value is greater than the first width value.

[0009] Furthermore, the first pushing member is a magnetic member, and the two first pushing members have opposite magnetic properties; or, The disassembly device further includes two first elastic elements, which are respectively sleeved on the outside of the two first pushers. The first elastic elements elastically connect the positioning element and the corresponding first pusher. When the second pusher moves from the second position to the first position, the two first elastic elements are used to push the two first pushers to move towards each other.

[0010] Furthermore, the first retaining ring has two ends respectively disposed on both sides of its opening, the two ends of the first retaining ring respectively passing through the first object and inserting into the second object, and the second pusher is used to widen the opening so that the two ends of the first retaining ring disengage from the second object.

[0011] Furthermore, the disassembly device also includes: A threaded rod, threadedly connected to the positioning member and disposed at the opposite end of the second push member in the first direction, the threaded rod being screwed into the positioning member in the positive direction of the first direction to push the second push member to move in the positive direction of the first direction; and The second elastic element is sleeved outside the second pusher and elastically connects the positioning element and the second pusher. During the process of the threaded rod rotating out in the opposite direction relative to the positioning element in the first direction, the second elastic element is used to push the second pusher to move in the opposite direction in the first direction.

[0012] Furthermore, the disassembly device further includes a connecting rod or a connecting rod and a third elastic element; The connecting rod is disposed between the second pushing member and the threaded rod, the connecting rod is detachably connected to the opposite end of the second pushing member in the first direction, and the threaded rod is rotatable relative to the connecting rod; The third elastic element is sleeved on the connecting rod and elastically connects the positioning element and the connecting rod. When the threaded rod is rotated out in the opposite direction relative to the positioning element in the first direction, the third elastic element is used to push the connecting rod to move in the opposite direction in the first direction.

[0013] Furthermore, the disassembly device also includes a kit, which is fitted over the first object, with one end of the kit abutting against the positioning member in the opposite direction of the first direction.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: In this disassembly device, the positioning member is inserted into the cavity of the first object to position the first object, and the second pushing member moves forward along the first direction to drive the first pushing member to pass through the through hole and push the inner side of the first snap ring, thereby expanding the opening of the first snap ring, so that the snap ring can be removed from the first object. This not only simplifies the disassembly operation process, reduces the operation difficulty, and improves the snap ring disassembly efficiency, but also, since the positioning member is inserted into the cavity of the first object during the disassembly process, the first pushing member does not directly contact the appearance surface of the first object and other objects, which can effectively avoid scratches, bumps and other damage, prevent the first object and other objects from being scrapped due to irreparable damage, improve the product appearance quality, and reduce production cost waste.

Detailed Implementation

[0032] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the invention.

[0033] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0035] Please refer to Figures 5 to 16The disassembly device of this invention includes a positioning member 1, a first pushing member 2, and a second pushing member 3. The positioning member 1 is used to position a first object 1000. A first retaining spring 2000 is embedded in the first object 1000. The first retaining spring 2000 surrounds a first direction and has an opening 2010. The first object 1000 has a cavity 1010 and a through hole 1020. The cavity 1010 extends along the first direction. The through hole 1020 penetrates the outer surface of the first object 1000 and the cavity 1010. The through hole 1020 is correspondingly arranged with the first retaining spring 2000. The positioning member 1 is inserted into the cavity 1010. The positioning member 1 has a first mounting hole 11 and a second mounting hole 12. The first mounting hole 11 extends along the first direction. The second mounting hole 12 is formed on the hole wall of the first mounting hole 11 and is coaxially connected with the through hole 1020. The first pusher 2 is inserted into the second mounting hole 12. The first pusher 2 has a first end 2a and a second end 2b that are axially opposite each other in the second mounting hole 12. The first end 2a of the first pusher 2 faces the first retaining ring 2000. The second pusher 3 is inserted into the first mounting hole 11 and abuts against the second end 2b of the first pusher 2. The second pusher 3 can move forward in a first direction to push the first pusher 2 through the through hole 1020 to push the first retaining ring 2000 away from the first object 1000, thereby widening the opening 2010. In other words, during the forward movement of the second pusher 3 along the first direction, the second pusher 3 can push the first pusher 2 from the second assembly hole 12 into the through hole 1020. As the second pusher 3 continues to move forward along the first direction, the first pusher 2 gradually moves to abut against the first retaining spring 2000 and pushes the first retaining spring 2000 away from the first object 1000, thereby expanding the width of the opening 2010.

[0036] In this embodiment of the invention, the positioning member 1 is inserted into the cavity 1010 of the first object 1000 to position the first object 1000. The second pushing member 3 moves forward in the first direction to drive the first pushing member 2 to pass through the through hole 1020 from inside the first object 1000 and push the inner side of the first retaining ring 2000, thereby expanding the width of the opening 2010 of the first retaining ring 2000. When the first retaining ring 2000 is no longer stuck to the outer periphery of the first object 1000, the retaining ring can be removed from the first object 1000. This not only simplifies the disassembly process, reduces the difficulty of operation, and improves the efficiency of retaining ring disassembly, but also, since the positioning member 1 is inserted into the cavity 1010 of the first object 1000 during the disassembly process, the first pushing member 2 does not directly contact the outer surface of the first object 1000 and other objects, which can effectively avoid scratches, bumps and other damage, prevent the first object 1000 and other structures from being scrapped due to irreparable damage, and reduce production cost waste.

[0037] In some implementation methods, please refer to Figure 2 and Figure 4 A first groove 1030 is formed on the outer surface of the first object 1000. The first groove 1030 is used to engage the first retaining spring 2000. The first groove 1030 can assemble and position the first retaining spring 2000, ensuring that the first retaining spring 2000 will not fall off in the initial state (assembled state). A through hole 1020 connects the first groove 1030 and the cavity 1010. As an example, the axis of the through hole 1020 extends along a second direction, which is perpendicular to the first direction, which can reduce force loss and improve the thrust transmission efficiency. In the initial state, the first retaining spring 2000 is engaged in the first groove 1030, that is, the inner side of the first retaining spring 2000 abuts against the bottom surface of the first groove 1030. When the second pusher 3 pushes the first pusher 2 to move, the width of the opening 2010 is expanded, allowing the first retaining spring 2000 to disengage from the first groove 1030, that is, the first retaining spring 2000 is removed from the first object 1000.

[0038] As an example, the width of the opening 2010 refers to the size of the opening 2010 in the second direction.

[0039] In some implementation methods, please refer to Figure 2 The first retaining ring 2000 has two ends 2020 respectively located on both sides of the opening 2010, and the distance between the two ends 2020 is the width of the opening 2010. In the initial state, the two ends 2020 of the first retaining ring 2000 pass through the first object 1000 and are inserted into the second object 3000. The second pushing member 3 can also be used to widen the opening 2010, so that the two ends 2020 of the first retaining ring 2000 can be disengaged from the second object 3000, thereby separating the second object 3000 from the first object 1000 and the first retaining ring 2000.

[0040] As one implementation method, please refer to Figure 4 The first object 1000 may include a body 1040 and two limiting ribs 1050 protruding from the body 1040. A first groove 1030 is formed on the outer periphery of the body 1040. The two limiting ribs 1050 are spaced apart in a second direction, and the two limiting ribs 1050 and the body 1040 together define an insertion groove 1060, into which the second object 3000 is inserted. Each of the two limiting ribs 1050 has a first insertion hole 1051 extending through the limiting rib 1050 in a second direction, and the two first insertion holes 1051 correspond one-to-one with the two ends 2020 of the first retaining spring 2000. Please refer to [reference needed]. Figure 3The second object 3000 has a second insertion hole 3010 extending through it in a second direction. When the second object 3000 is inserted into the insertion slot 1060, the second insertion hole 3010 is coaxially positioned between the two first insertion holes 1051, and the two ends 2020 of the first retaining ring 2000 pass through the corresponding first insertion holes 1051 and are inserted into the second insertion hole 3010. As an example, the second object 3000 can be inserted into the insertion slot 1060 in a third direction, with the third direction, the second direction, and the first direction being perpendicular to each other. Alternatively, the second object 3000 can be inserted into the insertion slot 1060 in the opposite direction to the first direction. It should be noted that the insertion direction of the second object 3000 and the first object 1000 can be set according to actual conditions, which will not be elaborated here.

[0041] As an example, please refer to Figures 1 to 4 The first object 1000 can be a plug at the end of the stylus barrel, and the second object 3000 can be a pen clip. It should be noted that the first object 1000 and the second object 3000 can also be other structures, which can be set according to the actual situation, and will not be elaborated here.

[0042] It should be noted that when using the width of the expanded opening 2010 in this embodiment, the opening 2010 can be enlarged according to actual needs.

[0043] In some examples, it is only necessary to separate the second object 3000 from the first object 1000 and the first retaining ring 2000. This can be achieved by expanding the width of the opening 2010 to allow the second object 3000 to dislodge from the expanded opening 2010. Specifically, the projections of both ends 2020 of the first retaining ring 2000 in the first direction should be outside the projection of the second object 3000 in the first direction. In other words, the two ends 2020 of the first retaining ring 2000 should dislodge from the second insertion hole 3010.

[0044] In other examples, if it is necessary to separate the first snap ring 2000, the first object 1000, and the second object 3000, then at least the width of the opening 2010 needs to be expanded until the two ends 2020 of the first snap ring 2000 are dislodged from the second insertion hole 3010 and the two first insertion holes 1051, and then the second object 3000 and the first snap ring 2000 are removed in sequence.

[0045] In some implementation methods, please refer to Figure 7 , Figure 9 , Figures 11 to 13 as well as Figures 15 to 16The disassembly device includes two first pushers 2, and correspondingly, the positioning fixture includes two second mounting holes 12. The second pusher 3 is located between the two first pushers 2, and when the first pusher 2 moves in the positive direction of the first direction, the first pusher 2 can push the two second pushers 3 to move simultaneously.

[0046] In one embodiment, two first pushing members 2 are symmetrically arranged on both sides of the second pushing member 3 in the second direction. When the second pushing member 3 moves in the positive direction of the first direction, it simultaneously applies a pushing force to the two first pushing members 2, driving the two first pushing members 2 to move synchronously along their respective second mounting holes 12, while simultaneously pushing the two sides of the opening 2010 of the first retaining ring 2000. This embodiment can simultaneously push the two sides of the opening 2010 of the first retaining ring 2000, improving the stability of disassembly.

[0047] As one implementation method, please refer to Figure 13 Two first pushers 2 are symmetrically arranged about the opening 2010. Specifically, the two ends 2020 of the first retaining ring 2000 are end 2020a and end 2020b, respectively. When the second pusher 3 moves forward in the first direction, end 2020a moves away from end 2020b under the action of the first pusher 2. At the same time, end 2020b moves away from end 2020a under the action of the other first pusher 2, that is, end 2020a and end 2020b move in opposite directions synchronously.

[0048] In this embodiment, the two first pushing members 2 are symmetrically distributed about the opening 2010 of the first retaining spring 2000. After the pushing force of the second pushing member 3 is transmitted to the two first pushing members 2, the two first pushing members 2 act on the two ends 2020 of the first retaining spring 2000 respectively, driving the two ends 2020 to move away from each other in a synchronous opposite direction, so that the opening 2010 expands evenly, ensuring that the first retaining spring 2000 is subjected to uniform force, avoiding the twisting and deformation of the first retaining spring 2000, and at the same time accelerating the expansion speed of the opening 2010, improving the disassembly efficiency, further protecting the structural integrity of the first retaining spring 2000, and facilitating reuse.

[0049] As an example, please refer to Figure 13 The two first pushers 2 are symmetrically arranged in the radial direction of the first retaining spring 2000, which can reduce force loss, ensure uniform expansion of the opening 2010, and at the same time avoid relative sliding between the first pushers 2 and the first retaining spring 2000, thereby improving the stability and reliability of the push.

[0050] In some embodiments, the second pusher 3 is movable between a first position and a second position, the first position and the second position being sequentially arranged along the positive direction of a first direction. Figure 12The second jacking component is the second jacking component 3 in the first position. Figure 16 The second pushing member is the second pushing member 3 in the second position. Correspondingly, the first pushing member 2 can move between the third and fourth positions. For example, the third and fourth positions are arranged opposite each other in the second direction. Figure 12 and Figure 13 The first jacking component in the middle is the first jacking component 2, which is in the third position. Figure 16 The first jacking member in the middle is the first jacking member 2 in the fourth position. In this embodiment, please refer to... Figure 5 , Figure 6 as well as Figures 11 to 13 When the second pusher 3 is in the first position, it is in its initial state. At this time, the first pusher 2 is also in its initial third position and is not in contact with the first retaining spring 2000. When the second pusher 3 moves to the second position in the first direction, please refer to... Figures 14 to 16 The first pusher 2 is moved to the fourth position along the second direction, pushing the first retaining spring 2000 to enlarge the opening 2010. After disassembly, the second pusher 3 returns to the first position, and the first pusher 2 also returns to the third position.

[0051] Please refer to Figure 5 , Figure 6 as well as Figures 11 to 13 When the second pusher 3 is in the first position, both first pushers 2 are in the third position. The second ends 2b of the two first pushers 2 in the third position abut against each other or there is a first gap between the second ends 2b of the two first pushers 2 in the third position. When the second pusher 3 is in the first position, the first retaining spring 2000 is in the initial state, that is, the inner side of the first retaining spring 2000 abuts against the bottom surface of the first groove 1030. At this time, the width of the opening 2010 is the first width value.

[0052] Please refer to Figures 14 to 16When the second pusher 3 is in the second position, both first pushers 2 are in the fourth position. The second ends 2b of the two first pushers 2 in the fourth position have a second gap, which is larger than the first gap. When the second pusher 3 is in the second position, the width of the opening 2010 is a second width value, which is larger than the first width value. That is, the opening 2010 is expanded. In some examples, the second width value can be greater than the length of the second insertion hole 3010, at least enough to push both ends 2020 of the first retaining ring 2000 completely outside the second object 3000, thereby allowing the second object 3000 to separate from the first retaining ring 2000 and the first object 1000. In other examples, the second width value may also be greater than the distance between the two limiting ribs 1050 on opposite sides in the second direction, that is, the two ends 2020 of the first snap ring 2000 disengage from the two first insertion holes 1051, at which point both the second object 3000 and the first snap ring 2000 can be removed from the first object 1000.

[0053] In some embodiments, after the second object 3000 or the second object 3000 and the first retaining ring 2000 are removed (i.e., after disassembly is completed), the second pushing member 3 returns to the first position, releasing the pushing force on the first pushing member 2. The first pushing member 2 can then return to the third position, thereby disengaging the first pushing member 2 from the through hole 1020, allowing the first object 1000 to be removed from the positioning fixture. As an example, the first pushing member 2 can exit from the through hole 1020 and return to the third position under the action of the first force, no longer interfering with the first object 1000. At this time, the first object 1000 can be removed from the positioning member 1.

[0054] In one implementation, the first force can be magnetic attraction. For example, both first pushing members 2 are magnetic, and their magnetic properties are opposite. Initially, the two first pushing members 2 attract each other, abutting together or with a small gap. During the forward movement of the second pushing member 3 along the second direction, the pushing force of the second pushing member 3 overcomes the magnetic attraction, causing the two first pushing members 2 to separate. After disassembly, the second pushing member 3 returns to the first position, and the magnetic attraction causes the two first pushing members 2 to attract each other and move towards each other along the second direction, thus automatically returning to the third position. In this embodiment, the first pushing member 2 utilizes magnetic attraction for reset, which not only simplifies the structure and eliminates the need for additional elastic components, reducing the structural complexity and manufacturing cost of the device, but also ensures smooth and reliable reset.

[0055] In one implementation, the first force can be a thrust. As an example, the disassembly device further includes two first elastic elements, each corresponding to one of the two first pushing members 2, which elastically connect the positioning member 1 and the corresponding first pushing member 2. When the second pushing member 3 is in the second position, the first elastic elements are compressed between the positioning member 1 and the first pushing member 2. During the movement of the second pushing member 3 from the second position to the first position, under the rebound action of the two first elastic elements, the two first elastic elements respectively push the two first pushing members 2 to move towards each other in the second direction. When the second pushing member 3 moves to the first position, under the action of the first elastic elements, the first pushing member 2 returns to the third position.

[0056] In this embodiment, the first elastic element is sleeved outside the first pushing member 2. When the second pushing member 3 pushes the first pushing member 2 to move outward along the second direction towards the positioning member 1, the first elastic element is compressed, storing elastic potential energy. After disassembly, the second pushing member 3 resets, the elastic potential energy is released, and the first elastic element pushes the first pushing member 2 to move in opposite directions towards the positioning member 1 and retract into the positioning member 1 until the first pushing member 2 resets to the third position. Because the first elastic element has a buffering effect, it can alleviate the impact force during the pushing process, protect the first pushing member 2 and the first retaining spring 2000, and extend the service life of the device.

[0057] As an example, the first elastic element can be a spring. It should be noted that in other embodiments, the first elastic element can also be other elastic structures, which can be set according to the actual situation, and will not be elaborated here.

[0058] In other examples, when the first force is a thrust, the disassembly device may not include the first elastic element. For example, after the first retaining ring 2000 is removed and the second pusher 3 moves to the first position, a tool such as a needle can be used to push the first end 2a of the first pusher 2, causing the first pusher 2 to move along the second mounting hole 12 toward the second pusher 3 (into the positioning member 1). When the second end 2b of the first pusher 2 abuts against the second pusher 3, the first pusher 2 returns to the third position. At this time, the first pusher 2 will not interfere with the first object 1000, and the first object 1000 can be removed from the positioning member 1.

[0059] It should be noted that the first pusher 2 can also be returned to the third position in other ways, which can be set according to the actual situation, and will not be elaborated here.

[0060] In some implementation methods, please refer to Figure 9 , Figure 12 and Figure 16The first pushing member 2 has a first inclined surface 21, which is disposed at the second end 2b of the first pushing member 2 and is inclined relative to the first direction. The second pushing member 3 has a second inclined surface 31, which is disposed corresponding to the first inclined surface 21 and is also inclined relative to the first direction. During the forward movement of the second pushing member 3 along the first direction, that is, during the movement of the second pushing member 3 pushing the first pushing member 2, the first inclined surface 21 and the second inclined surface 31 slide in contact. Similarly, during the reverse movement of the second pushing member 3 along the first direction, the first inclined surface 21 and the second inclined surface 31 slide in contact.

[0061] In this embodiment, the first inclined surface 21 and the second inclined surface 31 cooperate with each other and are both inclined relative to the first direction. When the second pushing member 3 moves in the positive direction of the first direction, the second inclined surface 31 slides into contact with the first inclined surface 21, converting the axial thrust of the second pushing member 3 into the radial thrust of the first pushing member 2 in the second direction through the guiding effect of the inclined surface. This drives the first pushing member 2 to move and push the first retaining spring 2000. That is, the cooperation of the first inclined surface 21 and the second inclined surface 31 realizes the conversion of the force direction, making the layout of each component more reasonable and avoiding interference between axial and radial movements; at the same time, the sliding contact reduces friction, reduces component wear, and improves the service life of the device.

[0062] As one implementation method, please refer to Figure 9 , Figure 12 and Figure 16 The second inclined surface 31 includes a first face 311 and a second face 312, which are arranged sequentially along the positive direction of the first direction. The angle between the first face 311 and the first direction is equal to the angle between the first inclined surface 21 and the first direction, and the angle between the second face 312 and the first direction is greater than the angle between the first inclined surface 21 and the first direction. That is, during the movement of the second pusher 3 along the positive direction of the first direction, the first inclined surface 21 first slides into contact with the second face 312, and then slides into contact with the first face 311.

[0063] In this embodiment, during the initial stage of the second pushing member 3 moving forward along the first direction, the first inclined surface 21 contacts the second surface 312 with a larger included angle. The larger included angle of the second surface 312 allows for a small stroke to push the first pushing member 2 to generate a larger radial displacement, quickly completing the initial expansion of the opening 2010 of the first retaining ring 2000, effectively improving disassembly efficiency. Then, the first inclined surface 21 slides along the second surface 312 until it contacts the first surface 311 with an appropriate included angle, which stabilizes the radial movement speed of the first pushing member 2, effectively controlling the expansion range of the opening 2010 of the first retaining ring 2000. This prevents excessive pushing later from causing plastic deformation of the first retaining ring 2000 or damage to the structure of the first object 1000 and the second object 3000. Simultaneously, the segmented inclined surface structure can disperse the contact stress during the pushing process, reducing contact wear between the first inclined surface 21 and the second inclined surface 31, and extending the service life of the first pushing member 2 and the second pushing member 3.

[0064] As an example, please refer to Figure 9 The first pusher 2 also has a first surface 22, which is located at the second end 2b of the first pusher 2. The first surface 22 is parallel to the first direction, and the first inclined surface 21 and the first surface 22 are arranged sequentially along the positive direction of the first direction. The phrase "the second ends 2b of the two first pushers 2 in the third position abut each other" above refers to the first surfaces 22 of the two first pushers 2 in the third position abutting each other. Please refer to [reference needed]. Figure 12 The first gap between the second ends 2b of the two first pushers 2 in the third position mentioned above refers to the first gap between the first surfaces 22 of the two first pushers 2 in the third position. The second gap between the second ends 2b of the two first pushers 2 in the fourth position mentioned above refers to the second gap between the first surfaces 22 of the two first pushers 2 in the fourth position. Please refer to [reference needed]. Figure 16 .

[0065] In some implementation methods, please refer to Figure 9 , Figure 12 and Figure 16Along the direction from the first end 2a to the second end 2b of the first pusher 2, the first pusher 2 sequentially includes a first ejector pin portion 23 and a first flange portion 24, which are integrally connected. A first inclined surface 21 and a first surface 22 are disposed on the side of the first flange portion 24 away from the first ejector pin portion 23. Along the direction from the first end 2a to the second end 2b of the first pusher 2, the second mounting hole 12 includes a first hole section 121 and a second hole section 122 coaxially arranged, with the diameter of the second hole section 122 being larger than the diameter of the first hole section 121. The first ejector pin portion 23 is movably inserted into the first hole section 121 along the axis of the second mounting hole 12, and the first flange portion 24 is movably inserted into the second hole section 122 along the axis of the second mounting hole 12.

[0066] As an example, please refer to Figure 13 The second hole segments 122 of the two second assembly holes 12 are connected to form a connected chamber. The first flange portions 24 of the two first push members 2 can move in this chamber and cooperate with the second inclined surface 31 of the second push member 3. This simplifies the processing of the positioning member 1, eliminates the need to process the two independent second hole segments 122 separately, and reduces manufacturing costs. At the same time, the connected chamber facilitates the installation and movement of the second push member 3 and ensures that the two first push members 2 are subjected to uniform force.

[0067] As an example, when the disassembly device includes a first elastic member, the first elastic member is received in the second mounting hole 12 and sleeved on the outside of the first ejector pin portion 23. One end of the first elastic member abuts against the bottom of the hole in the second hole section 122, and the other end of the first elastic member abuts against the side of the first flange portion 24 facing the first ejector pin portion 23.

[0068] It should be noted that in other embodiments, the disassembly device may also include one, three, four or more first pushers 2. Regardless of how many first pushers 2 the disassembly device includes, when the second pusher 3 moves in the positive direction of the first direction, it can push all the first pushers 2 to push the first retaining ring 2000 at the same time. Furthermore, the number of second mounting holes 12 is equal to the number of first pushers 2, and the two are set in a one-to-one correspondence. This can be set according to the actual situation, and will not be elaborated here.

[0069] In some implementation methods, please refer to Figure 5 , Figure 7 , Figures 10 to 11 ,as well as Figures 14 to 15 The disassembly device also includes a threaded rod 5. The threaded rod 5 is threaded to the positioning member 1, and the threaded rod 5 is disposed at the end of the second push member 3 opposite to the first direction. The threaded rod 5 is used to screw into the positioning member 1 in the positive direction of the first direction to push the second push member 3 to move in the positive direction of the first direction until the second push member 3 moves to the second position.

[0070] In this embodiment, the threaded rod 5 is threadedly connected to the positioning member 1. By rotating the threaded rod 5, the rotational motion can be converted into the axial linear motion of the second pushing member 3. Moreover, the threaded connection has a self-locking function, which can prevent the second pushing member 3 from accidentally retracting during the process of pushing the first pushing member 2. This effectively controls the moving distance and pushing force of the second pushing member 3, and can also prevent damage to the components caused by excessive pushing force. Furthermore, it is easy to operate, can achieve fine adjustment, and improves the accuracy and controllability of disassembly.

[0071] As one implementation method, please refer to Figure 11 and Figure 15 The positioning member 1 includes a threaded hole 15 coaxially connected with the first mounting hole 11. The threaded hole 15 is located at the opposite end of the first mounting hole 11 in the first direction. The threaded rod 5 is threadedly connected to the threaded hole 15, and the positive end of the threaded rod 5 in the first direction can extend into the first mounting hole 11.

[0072] As one implementation method, please refer to Figure 5 , Figure 7 , Figures 10 to 11 ,as well as Figures 14 to 15 Along the reverse direction of the first direction, the threaded rod 5 includes a threaded part 51 and a screwing handle part 52 in sequence. The threaded part 51 and the screwing handle part 52 are fixed as one piece. The threaded part 51 is threadedly connected to the threaded hole 15. The end of the threaded part 51 away from the screwing handle part 52 extends into the first assembly hole 11. The screwing handle part 52 is located outside the positioning member 1, which is convenient for the operator to hold and rotate. Without the aid of additional tools, the threaded rod 5 can be driven to screw in or out, thereby controlling the movement of the second push member 3.

[0073] In some implementation methods, please refer to Figure 7 , Figure 11 as well as Figure 15 The disassembly device also includes a second elastic element 41. The second elastic element 41 is sleeved outside the second pushing member 3 and elastically connects the positioning member 1 and the second pushing member 3. When the second pushing member 3 is in the second position, the second elastic element 41 is compressed between the second pushing member 3 and the positioning member 1. During the process of the threaded rod 5 rotating out in the opposite direction relative to the positioning member 1, under the rebound action of the second elastic element 41, the second elastic element 41 pushes the second pushing member 3 to move in the opposite direction in the first direction, so that the second pushing member 3 can return from the second position to the first position.

[0074] In this embodiment, the second elastic element 41 is sleeved outside the second pushing element 3. When the second pushing element 3 is pushed to the second position by the threaded rod 5, the second elastic element 41 is compressed, storing elastic potential energy. After disassembly, the threaded rod 5 is unscrewed, the elastic potential energy is released, and the second elastic element 41 pushes the second pushing element 3 to move in the opposite direction of the first direction, automatically resetting to the first position. This simplifies the operation process and improves efficiency. At the same time, the buffering effect of the elastic element can alleviate the impact force when the threaded rod 5 is pushed, protecting the second pushing element 3 and the positioning element 1, and extending the service life of the device.

[0075] As one implementation method, please refer to Figure 7 , Figure 11 as well as Figure 15 Along the reverse direction of the first direction, the second pusher 3 sequentially includes a second ejector pin portion 32, a second flange portion 33, and a third flange portion 34, which are integrated. A second inclined surface 31 is disposed at the end of the second ejector pin portion 32 away from the second flange portion 33. A second elastic member 41 is sleeved on the second ejector pin portion 32 and the second flange portion 33, with one end of the second elastic member 41 in the positive direction of the first direction abutting against the surface of the first mounting hole 11, and the other end of the second elastic member 41 in the opposite direction of the first direction abutting against the side of the third flange portion 34 facing the second flange portion 33.

[0076] As an example, the second elastic element 41 can be a spring. It should be noted that in other embodiments, the second elastic element 41 can also be other elastic structures, which can be set according to the actual situation, and will not be described in detail here.

[0077] In some implementation methods, please refer to Figure 7 , Figure 11 as well as Figure 15 The disassembly device also includes a connecting rod 6. The connecting rod 6 is disposed between the second pushing member 3 and the threaded rod 5. The connecting rod 6 is detachably connected to the end of the second pushing member 3 opposite to the first direction, and the threaded rod 5 is rotatable relative to the connecting rod 6. As an example, the connecting rod 6 is threadedly connected to the second pushing member 3.

[0078] In this embodiment, the connecting rod 6 connects the second pushing member 3 and the threaded rod 5. When the threaded rod 5 rotates, the thrust is transmitted to the second pushing member 3 through the connecting rod 6, driving the second pushing member 3 to move. This avoids direct contact and friction damage between the second pushing member 3 and the threaded rod 5. The connecting rod 6 and the second pushing member 3 are detachably connected, facilitating disassembly, maintenance, and replacement of the connecting rod 6. Furthermore, the distance between the second pushing member 3 and the threaded rod 5 can be flexibly adjusted by replacing the connecting rod 6 with different lengths, adapting to different sizes of positioning members 1 and pushing members, thus improving the adaptability of the device.

[0079] As one implementation method, please refer to Figure 7 , Figure 11 as well as Figure 15 The connecting rod 6 is detachably connected to the third flange portion 34. As an example, the connecting rod 6 is threadedly connected to the third flange portion 34.

[0080] As one implementation method, please refer to Figure 7 , Figure 11 as well as Figure 15 The disassembly device also includes a third elastic element 42. The third elastic element 42 is sleeved around the connecting rod 6 and elastically connects the positioning element 1 and the connecting rod 6. When the second pushing element 3 is in the second position, the third elastic element 42 is compressed between the connecting rod 6 and the positioning element 1. When the threaded rod 5 rotates out in the opposite direction relative to the positioning element 1, the third elastic element 42, under its rebound action, pushes the connecting rod 6 to move in the opposite direction of the first direction.

[0081] In this embodiment, the third elastic element 42 is sleeved outside the connecting rod 6. When the second pushing member 3 moves to the second position, the connecting rod 6 moves synchronously to compress the third elastic element 42, storing elastic potential energy. After disassembly, the threaded rod 5 is unscrewed, and the third elastic element 42 rebounds, pushing the connecting rod 6 to move in the opposite direction along the first direction, thereby driving the second pushing member 3 to reset. Therefore, the third elastic element 42 further improves the reliability of the reset of the second pushing member 3, avoiding reset failure caused by the failure of a single elastic element. At the same time, the elastic element is sleeved outside the connecting rod 6, resulting in a compact structure that does not interfere with the movement of other components.

[0082] As one implementation method, please refer to Figure 7 , Figure 11 as well as Figure 15 Along the reverse direction of the first direction, the connecting rod 6 sequentially includes a rod portion 61 and a fourth flange portion 62, which are integrally connected. A third elastic member 42 is sleeved on the rod portion 61, with one end of the third elastic member 42 in the positive direction of the first direction abutting the surface of the first mounting hole 11, and the other end of the third elastic member 42 in the opposite direction of the first direction abutting the side of the fourth flange portion 62 facing the rod portion 61. In some examples, the disassembly device further includes a gasket 8, which is placed between the fourth flange portion 62 and the third elastic member 42.

[0083] As an example, the third elastic element 42 can be a spring. It should be noted that in other embodiments, the third elastic element 42 can also be other elastic structures, which can be set according to the actual situation, and will not be described in detail here.

[0084] It should be noted that in other embodiments, the disassembly device may not include the second elastic element 41 and the third elastic element 42, which can be set according to the actual situation, and will not be elaborated here. As an example, when the threaded rod 5 is screwed out in the opposite direction relative to the positioning member 1 in the first direction, the threaded rod 5 can drive the connecting rod 6 and the second pushing member 3 to move in the opposite direction in the first direction.

[0085] In some implementation methods, please refer to Figure 5 , Figure 7 , Figure 10 , Figure 11 , Figure 14 and Figure 15 In the opposite direction of the first direction, the first positioning member 1 includes a contour block 16, a pad block 17, and a fixing block 18, which are fixedly connected by screws. As an example, the contour block 16 and the pad block 17 are fixedly connected by a first screw 91a, and the pad block 17 and the fixing block 18 are fixedly connected by a second screw 91b. The contour block 16 and the pad block 17 together define the first mounting hole 11, the contour block 16 defines the second mounting hole 12, the fixing block 18 defines the threaded hole 15, the first positioning member 1 also has a third mounting hole 13 and a fourth mounting hole 14, the first mounting hole 11, the third mounting hole 13, the fourth mounting hole 14 and the threaded hole 15 are coaxially connected, the pad block 17 defines the third mounting hole 13, the pad block 17 and the fixing block 18 define the fourth mounting hole 14, the diameter of the third mounting hole 13 is smaller than the diameter of the first mounting hole 11 and the diameter of the fourth mounting hole 14, the diameter of the fourth mounting hole 14 is larger than the diameter of the threaded hole 15, and the third elastic member 42 is received in the fourth mounting hole 14.

[0086] As one implementation method, please refer to Figure 6 , Figure 8 , Figure 11 and Figure 15The contour block 16 includes a positioning portion 161 and a contour portion 162 formed on one end face of the positioning portion 161 in the positive direction of the first direction. The positioning portion 161 and the contour portion 162 together define a first mounting hole 11, and the contour portion 162 defines a second mounting hole 12. The contour portion 162 is inserted into the cavity 1010 of the first object 1000, and the end face of the first object 1000 in the opposite direction of the first direction abuts against the end face of the positioning portion 161 in the positive direction of the first direction. As an example, the first object 1000 has a first limiting surface 1070 and a first anti-rotation surface defining the cavity 1010. The first limiting surface 1070 is disposed around the first direction, and the outer surface of the contour portion 162 includes a second limiting surface 1621 and a second anti-rotation surface 1622. When the contouring part 162 is inserted into the cavity 1010 of the first object 1000, and the end face of the first object 1000 in the opposite direction abuts against the end face of the positioning part 161 in the positive direction, the first limiting surface 1070 abuts against the second limiting surface 1621, and the first anti-rotation surface abuts against the second anti-rotation surface 1622.

[0087] In this embodiment, the contouring portion 162 of the contouring block 16 is adapted to the shape of the cavity 1010 of the first object 1000. After the contouring portion 162 is inserted into the cavity 1010, the first limiting surface 1070 and the second limiting surface 1621 abut against each other to restrict the radial movement of the first object 1000. The first anti-rotation surface and the second anti-rotation surface 1622 abut against each other to restrict the circumferential rotation of the first object 1000. The positioning portion 161 is used to limit the end face of the first object 1000 to prevent the contouring portion 162 from being over-inserted into the first object 1000. Moreover, the abutment between the first anti-rotation surface and the second anti-rotation surface 1622 can further improve the positioning accuracy and ensure that the through hole 1020 can be coaxially aligned with the second mounting hole 12.

[0088] As one implementation method, please refer to Figures 6 to 8 The contour block 16 is formed by the mating and fixing of two opposing petals 163 arranged in a second direction. The two petals 163 are symmetrically arranged, and together with the pad block 17, they define a first mounting hole 11. As an example, each of the two petals 163 has a second mounting hole 12. The two petals 163 are positioned by locating pins 92 and fixed by third screws 91c.

[0089] In some implementation methods, please refer to Figure 5 , Figure 7 , Figure 11 , Figure 12 , Figure 14 and Figure 15The disassembly device also includes a kit 7, which is fitted over the first object 1000. The end of the kit 7 facing away from the first object in the first direction abuts against the positioning member 1. Furthermore, there is sufficient clearance between the kit 7 and the first retaining spring 2000, meaning that the kit 7 will not interfere with the expansion of the opening 2010 of the first retaining spring 2000 and will not affect the disassembly process. In this embodiment, the kit 7 can provide auxiliary positioning and protection for the first object 1000. It not only prevents the first object 1000 from shaking during the disassembly of the first retaining spring 2000 or the second object 3000, but also protects the exterior surface of the first object 1000, preventing scratches from friction with other components and further improving the appearance protection effect.

[0090] As an example, the method of using the disassembly device is as follows: First, align the cavity 1010 of the first object 1000 (such as the plug of a stylus) with the contour part 162 of the positioning member 1, insert the contour part 162 into the cavity 1010, so that the end face of the first object 1000 abuts against the positioning part 161 of the positioning member 1, and at the same time ensure that the through hole 1020 of the first object 1000 is coaxially aligned with the second mounting hole 12 of the positioning member 1, thereby completing the installation and positioning of the first object 1000. If only the second object 3000 (such as a pen clip) needs to be disassembled, rotate the threaded rod 5 so that it screws in along the first direction and pushes the second pusher 3 along the first direction. This drives the two first pushers 2 to move simultaneously in opposite directions along the second direction, passing through the through hole 1020 and pushing the inside of the first retaining ring 2000. This expands the opening 2010 of the first retaining ring 2000 until the two ends 2020 of the first retaining ring 2000 disengage from the second insertion hole 3010 of the second object 3000. The second object 3000 can then be removed along the third direction. If it is also necessary to separate the first retaining ring 2000 and the first object 1000, rotate the threaded rod 5 so that the opening 2010 of the first retaining ring 2000 expands until the two ends 2020 of the first retaining ring 2000 disengage from the two first insertion holes 1051. Then the first retaining ring 2000 can be removed, completing the disassembly of the first retaining ring 2000. During the reset process, the threaded rod 5 is rotated in the opposite direction, causing the threaded rod 5 to rotate out in the opposite direction of the first direction. The second pusher 3 is reset to the first position under the action of the second elastic member 41 and the third elastic member 42. At the same time, the first pusher 2 is reset to the third position under the action of magnetic attraction and disengages from the through hole 1020, no longer interfering with the first object 1000. At this time, the first object 1000 can be removed from the positioning member 1.

[0091] In some implementation methods, please refer to Figure 1In addition to the first object 1000, a second snap ring 4000 can also be snapped on. The second snap ring 4000 can also be used to elastically connect the first object 1000 and the second object 3000. The disassembly method of the second snap ring 4000 can be different from or the same as the disassembly method of the first snap ring 2000. It can be set according to the actual situation, which will not be elaborated here.

[0092] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0093] The above embodiments merely illustrate preferred implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention.
