[0001] This application relates to the technical field of disassembly tooling, and more particularly, to a disassembly device. Background Art

[0002] Some socket-mounted components include a first target member and a second target member, and the first target member is inserted through a receiving hole of the second target member. When removing the first target member from the second target member, some known techniques use disassembly tooling for disassembly. However, it can only be applied to components with a single structure, and the applicable range is relatively narrow. Summary of the Utility Model

[0003] This application provides a disassembly device to solve the technical problem that the applicable range of some known disassembly tooling is relatively narrow.

[0004] This application provides a disassembly device, including a base member, a pressing member, an adjusting assembly, and a jacking member. The base member includes a fixed portion, a first connecting portion, and a first end portion that are connected in sequence. The pressing member includes a pressing portion, a second connecting portion, and a second end portion that are connected in sequence, and the pressing member is spaced apart from the base member. One end of the adjusting assembly is rotatably connected to the second connecting portion, and the other end of the adjusting assembly is movably connected to the first connecting portion to adjust the distance between the first connecting portion and the second connecting portion. The jacking member is used to adjust the distance between the first end portion and the second end portion to drive the pressing member to rotate relative to the adjusting assembly and adjust the distance between the fixed portion and the pressing portion.

[0005] In a possible implementation:

[0006] A through first threaded hole is provided in the second end portion. One end of the jacking member abuts against the first end portion, and the other end of the jacking member is threadedly connected to the first threaded hole. The jacking member is configured to rotate relative to the second end portion to drive the second end portion to approach or move away from the first end portion, thereby driving the pressing member to rotate relative to the adjusting assembly.

[0007] In a possible implementation:

[0008] The jacking member includes an abutting end portion. The surface of the first end portion facing the second end portion is provided with a limiting groove that is concave inward in a direction away from the second end portion, and the abutting end portion abuts against the groove surface of the limiting groove.

[0009] In a possible implementation:

[0010] The lifting member further includes a threaded portion and a force-receiving portion. The threaded portion is threadedly connected to the first threaded hole. The force-receiving portion is connected between the abutting end portion and the threaded portion. The force-receiving portion is configured to drive the threaded portion to rotate relative to the second end portion when a force is applied.

[0011] In a possible implementation manner:

[0012] The lifting member includes an abutting end portion having an abutting surface that abuts against the first end portion. The abutting surface and the first end portion are configured to be in line contact or point contact.

[0013] In a possible implementation manner:

[0014] The adjusting assembly includes an adjusting rod and a pin shaft. One end of the adjusting rod is movably connected to the first connecting portion, and the other end of the adjusting rod is rotatably connected to the second connecting portion through the pin shaft.

[0015] In a possible implementation manner:

[0016] The second connecting portion is provided with a receiving hole. The adjusting rod extends into the receiving hole. There is a gap between the circumferential side surface of the adjusting rod and the hole surface of the receiving hole, so that the pressing member can rotate relative to the pin shaft, and the distance between the fixing portion and the pressing portion can float within a preset range.

[0017] In a possible implementation manner:

[0018] The disassembly device further includes an elastic member that elastically abuts between the adjusting assembly and the base member.

[0019] The present application further provides a disassembly device for disassembling a first target member from a second target member. The second target member is provided with a through receiving hole, and the first target member is received in the receiving hole. The disassembly device includes a base member, a pressing member, an adjusting assembly, and a lifting member. The base member includes a fixing portion, a first connecting portion, and a first end portion that are sequentially connected. The fixing portion is used to support the lower end of the second target member. The pressing member includes a pressing portion, a second connecting portion, and a second end portion that are sequentially connected. The pressing member is spaced apart from the base member. The pressing portion is used to abut against the first target member. One end of the adjusting assembly is rotatably connected to the second connecting portion, and the other end of the adjusting assembly is movably connected to the first connecting portion to adjust the distance between the first connecting portion and the second connecting portion. The lifting member is used to drive the pressing member to rotate relative to the adjusting assembly to reduce the distance between the fixing portion and the pressing portion, and to cause the pressing portion to push the first target member to move relative to the second target member.

[0020] After the fixing part is fixed relative to the second target part, the distance between the first end and the second end is increased by operating the lifting part, so that the pressing part rotates relative to the adjusting component, so that the pressing part has a tendency to move toward the fixing part and exerts a force on the first target part. After the force is greater than the friction between the first target part and the second target part, the first target part can be driven to move relative to the second target part, and finally the first target part can be removed from the second target part. When faced with the need to disassemble a first target part and a second target part with different sizes, if the spacing between the base part and the pressing part is fixed, when the size of the second target part in the spacing direction between the base part and the pressing part is too large, the fixing part will not be able to reliably abut the second target part. In this embodiment, by adjusting the spacing between the first connecting part and the second connecting part to ensure that when the fixing part is fixed to the second target part, the pressing part can stably and reliably abut the first target part, so that when the lifting part is actuated, the pressing part can stably apply force to the first target part, thereby ensuring the smooth disassembly of the first target part and the second target part. Therefore, the disassembly device of this embodiment can be applied to the disassembly needs of first target parts and second target parts of different sizes, and has a wide range of applications.

[0021] In one possible implementation:

[0022] A positioning groove is provided on a surface of the pressing portion facing the fixing portion. The positioning groove is concavely arranged in a direction away from the fixing portion. The positioning groove is used to limit the first target part. BRIEF DESCRIPTION OF THE DRAWINGS

[0074] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "or / and" used herein includes any and all combinations of one or more of the related listed items.

[0075] Some embodiments of the present application will be described in detail. In the case of no conflict, the following embodiments and the features in the embodiments may be combined with each other.

[0076] Referring to Figure 1 , in this embodiment, a disassembling device 100 is provided for disassembling a first target member 200 from a second target member 300. A through receiving hole 400 is formed in the second target member 300, and the first target member 200 is received in the receiving hole 400. The disassembling device 100 includes a base member 10, a pressing member 20, an adjusting assembly 30, and a lifting member 40. The base member 10 includes a fixing portion 11, a first connecting portion 12, and a first end portion 13 that are sequentially connected. The fixing portion 11 is used to support the lower portion of the second target member 300. The pressing member 20 includes a pressing portion 21, a second connecting portion 22, and a second end portion 23 that are sequentially connected. The pressing member 20 is spaced apart from the base member 10, and the pressing portion 21 is used to abut against the first target member 200. One end of the adjusting assembly 30 is rotatably connected to the second connecting portion 22, and the other end of the adjusting assembly 30 is movably connected to the first connecting portion 12 to adjust the distance between the first connecting portion 12 and the second connecting portion 22. The lifting member 40 is used to adjust the distance between the first end portion 13 and the second end portion 23. For example, the lifting member 40 increases the distance between the first end portion 13 and the second end portion 23, so that the pressing member 20 rotates relative to the adjusting assembly 30 through the second connecting portion 22, thereby reducing the distance between the fixing portion 11 and the pressing portion 21, and causing the pressing portion 21 to push the first target member 200 to move relative to the second target member 300 to disengage from the receiving hole 400.

[0077] Thus, after the fixing part 11 supports the second target part 300, by operating the jacking part 40, the distance between the first end part 13 and the second end part 23 is increased, so that the pressing part 20 rotates relative to the adjusting assembly 30, making the pressing part 21 tend to move towards the fixing part 11 and applying a force to the first target part 200. After the force is greater than the frictional force between the first target part 200 and the second target part 300, the first target part 200 can be driven to move relative to the second target part 300, and finally the first target part 200 is disassembled from the second target part 300. When facing the disassembly requirements of the first target part 200 and the second target part 300 with different sizes, if the distance between the base part 10 and the pressing part 20 is fixed, when the size of the second target part 300 in the interval direction between the base part 10 and the pressing part 20 is too large, it will cause the fixing part 11 to not reliably hold the second target part 300. In this embodiment, by adjusting the distance between the first connecting part 12 and the second connecting part 22, to ensure that when the fixing part 11 supports the second target part 300, the pressing part 21 can stably and reliably abut against the first target part 200, so that when the jacking part 40 acts, the pressing part 21 can stably apply a force to the first target part 200, and further ensure the smooth disassembly of the first target part 200 and the second target part 300. Therefore, the disassembly device 100 of this embodiment can be applied to the disassembly requirements of the first target part 200 and the second target part 300 with different sizes, and has a wide application range.

[0078] In some embodiments, referring to Figure 2 and Figure 3 , the base part 10 and the pressing part 20 are spaced apart along the first direction X. The length direction of the adjusting assembly 30 is parallel to the first direction X. The center line of the receiving hole 400 is substantially parallel to the first direction X. The adjusting assembly 30 is rotatably connected to the second connecting part 22 about a rotation axis, and the rotation axis is parallel to the second direction Y. The length direction of the base part 10 is parallel to the third direction Z, and the fixing part 11, the first connecting part 12 and the first end part 13 are sequentially connected along the third direction Z. The length direction of the pressing part 20 is parallel to the third direction Z, and the pressing part 21, the second connecting part 22 and the second end part 23 are sequentially connected along the third direction Z. The first direction X, the second direction Y and the third direction Z intersect each other.

[0079] In some embodiments, referring to Figure 2, the receiving hole 400 is a conical hole. When the disassembly device 100 works, the fixing part 11 corresponds to the end with the large aperture of the conical hole, and the pressing part 21 corresponds to the end with the small aperture of the conical hole. Thus, when the distance between the pressing part 21 and the fixing part 11 decreases, the pressing part 21 exerts a force on the first target part 200 from the small-hole end to the large-hole end of the conical hole, so that the first target part 200 can move relative to the conical hole, and a gap is formed between the circumferential side surface of the first target part 200 and the hole surface of the receiving hole 400. After that, the first target part 200 can be continuously pushed by the pressing part 21, or the first target part 200 can be removed from the second target part 300 by other devices, manual operations, etc., and the disassembly of the first target part 200 and the second target part 300 is completed. In other embodiments, the inner diameters of each part of the receiving hole 400 can also be set to be the same.

[0080] In some embodiments, refer to Figure 2 , the disassembly device 100 is applied to the suspension assembly 500. The suspension assembly 500 includes a swing arm 501, a swing arm ball joint 502, a steering knuckle 503, and a nut (not shown in the figure). The steering knuckle 503 is the second target part 300. The swing arm ball joint 502 is the first target part 200. The steering knuckle 503 is provided with a receiving hole 400. When the suspension assembly 500 is in a working state, the nut fixes the swing arm ball joint 502 to the steering knuckle 503. When it is necessary to disassemble the suspension assembly 500, first remove the nut, and then use the disassembly device 100 to remove the swing arm ball joint 502 from the steering knuckle 503.

[0081] Specifically, support the fixing part 11 at the lower end of the steering knuckle 503, and make the pressing part 21 abut against the upper end of the swing arm ball joint 502. By adjusting the adjusting assembly 30, the fixing part 11 and the pressing part 21 are clamped between the lower end of the steering knuckle 503 and the upper end of the swing arm ball joint 502, so that the disassembly device 100 is kept installed on the suspension assembly 500. Subsequently, the lifting part 40 moves relative to the second end part 23, and the distance between the first end part 13 and the second end part 23 increases. Under the action of the lever principle, the distance between the pressing part 21 and the fixing part 11 decreases, so that the pressing part 21 exerts a force on the swing arm ball joint 502 to move relative to the steering knuckle 503, causing the swing arm ball joint 502 and the steering knuckle 503 to generate relative displacement along the axial direction of the receiving hole 400, and then a gap is formed between the swing arm ball joint 502 and the hole surface of the receiving hole 400. After that, the swing arm ball joint 502 can be removed from the steering knuckle 503. In this way, the disassembly of the swing arm ball joint 502 and the steering knuckle 503 can be realized in a state where the structures of the swing arm ball joint 502 and the steering knuckle 503 are intact.

[0082] In some embodiments, refer to Figure 2The suspension assembly 500 further includes a tapered sleeve 504, which is disposed in the receiving hole 400, and the swing arm ball pin 502 is passed through the tapered sleeve 504. The suspension assembly 500 of this embodiment can further improve the axial load bearing capacity of the suspension assembly 500. However, after long-term use, the tapered sleeve 504 and the swing arm ball pin 502 of the suspension assembly 500 of this embodiment are tightly matched. If the ordinary disassembly method is used, the tapered sleeve 504 is easily separated from the steering knuckle 503, and the tapered sleeve 504 and the swing arm ball pin 502 remain in a matched state, so that the disassembly of the tapered sleeve 504 and the swing arm ball pin 502 is more difficult, and the tapered sleeve 504 and the swing arm ball pin 502 are easily damaged or even scrapped. When disassembling the suspension assembly 500 , the disassembly device 100 of this embodiment can ensure that the swing arm ball pin 502 is separated from the tapered sleeve 504 , and the tapered sleeve 504 remains in the steering knuckle 503 .

[0083] In some embodiments, see Figure 2 , a positioning groove C2 is provided on the surface of the pressing portion 21 facing the fixing portion 11. The positioning groove C2 is concavely arranged in a direction away from the fixing portion 11, and the positioning groove C2 is used to limit the first target part 200. During the use of the disassembly device 100, the pressing portion 21 will also rotate relative to the first target part 200. By allowing the first target part 200 to extend into the positioning groove C2, the first target part 200 can be prevented from being separated from the pressing portion 21, so as to ensure that the first target part 200 is subjected to a stable force, thereby improving the reliability of the disassembly operation.

[0084] In some embodiments, see Figure 2 The fixing portion 11 has a fixing groove C3 formed concavely toward the first end portion 13 on one side thereof away from the first end portion 13. The fixing groove C3 is matched with the side of the swing arm ball pin 502 and supported at the lower end of the steering knuckle 503. The shape of the fixing groove C3 can increase the contact area between the fixing portion 11 and the steering knuckle 503, thereby improving the supporting effect on the steering knuckle 503. At the same time, the fixing groove C3 can also avoid the swing arm ball pin 502 and the swing arm 501 from being dislodged, so that the swing arm ball pin 502 and the swing arm 501 can be smoothly separated from the steering knuckle 503.

[0085] In some embodiments, see Figure 2 A protrusion 14 is provided on the surface of the fixing portion 11 protruding toward the pressing portion 21. The protrusion 14 can strengthen the portion of the fixing portion 11 where the fixing groove C3 is provided, and improve the supporting effect of the fixing portion 11 on the steering knuckle 503, so that the disassembly device 100 remains stably arranged on the suspension assembly 500.

[0086] In some embodiments, see Figure 2, in the third direction Z, the thickness of the pressing portion 21 along the first direction X gradually decreases in the direction away from the second connecting portion 22. And the thickness of the pressing portion 21 is less than the thickness of the second connecting portion 22.

[0087] In some embodiments, referring to Figure 2 and Figure 3 , a through first threaded hole K1 is provided in the second end portion 23. One end of the lifting member 40 abuts against the first end portion 13, and the other end of the lifting member 40 is threadedly connected to the first threaded hole K1. The lifting member 40 is configured to rotate relative to the second end portion 23 to drive the second end portion 23 to approach or move away from the first end portion 13, thereby driving the pressing member 20 to rotate relative to the adjusting assembly 30.

[0088] Since one end of the lifting member 40 remains in abutment with the first end portion 13, during the rotation of the lifting member 40 relative to the second end portion 23, the second end portion 23 moves along the length direction of the lifting member 40, so as to realize the change in the distance between the second end portion 23 and the first end portion 13. Furthermore, the pressing member 20 rotates relative to the adjusting assembly 30, and the pressing portion 21 applies a force to the first target member 200.

[0089] In other embodiments, the lifting member 40 can also be rotatably connected to the first end portion 13. For example, the lifting member 40 and the first end portion 13 can be connected by means of a ball hinge fit.

[0090] In other embodiments, the lifting member 40 can also be configured such that one end is threadedly connected to the first end portion 13 and the other end abuts against the second end portion 23. Therefore, the cooperation relationship among the base member 10, the pressing member 20, and the lifting member 40 can be adjusted according to actual needs, and the present application does not make specific limitations thereto.

[0091] In some embodiments, referring to Figure 2 and Figure 4 , the lifting member 40 includes an abutting end portion 41. The surface of the first end portion 13 facing the second end portion 23 is provided with a limiting groove C1 that is recessed inward in the direction away from the second end portion 23, and the abutting end portion 41 abuts against the groove surface of the limiting groove C1. During the rotation of the lifting member 40 relative to the second end portion 23 under force and driving the pressing member 20 to rotate, the pressing member 20 drives the lifting member 40 to rotate relative to the base member 10 and generates an offset in the direction close to the fixing portion 11 along the length direction of the base member 10, making it possible for the lifting member 40 to disengage from the first end portion 13. In this embodiment, the limiting groove C1 can play a limiting role on the abutting end portion 41, keeping the abutting end portion 41 within the limiting groove C1, thereby reducing the possibility of the abutting end portion 41 disengaging from the first end portion 13, ensuring that the lifting member 40 can be stably supported on the first end portion 13, and improving the use reliability of the disassembly device 100.

[0092] In some embodiments, referring toFigure 2 , the abutting end portion 41 has an abutting surface P1, the abutting surface P1 abuts against the first end portion 13, and the structure between the abutting surface P1 and the first end portion 13 is a line contact or a point contact. In this way, during the rotation of the lifting member 40 relative to the second end portion 23, the lifting member 40 simultaneously moves offset relative to the first end portion 13, and the frictional force between the abutting surface P1 and the first end portion 13 is small, so that the force transmission efficiency can be improved, and then the disassembly efficiency can be improved.

[0093] In some embodiments, refer to Figure 2 , the abutting surface P1 can be configured as a spherical surface to form a point contact between the abutting end portion 41 and the surface of the first end portion 13. The abutting surface P1 can also be configured as an arc surface to form a line contact between the abutting end portion 41 and the surface of the first end portion 13.

[0094] In some embodiments, refer to Figure 2 and Figure 3 , the lifting member 40 further includes a threaded portion 42 and a force-receiving portion 43. The threaded portion 42 is threadedly connected to the first threaded hole K1, and the force-receiving portion 43 is connected between the abutting end portion 41 and the threaded portion 42. The force-receiving portion 43 is configured to drive the threaded portion 42 to rotate relative to the second end portion 23 after receiving a force.

[0095] In addition, since the force-receiving portion 43 is located between the abutting end portion 41 and the threaded portion 42, the driving tool of the force-receiving portion 43 does not need to occupy the space on both sides of the disassembly device 100 along the first direction X, reducing the space requirement for the disassembly device 100. In addition, by applying a force to the force-receiving portion 43 to drive the rotation of the lifting member 40, the force arm of the lifting member 40 is short, which can greatly reduce the possibility of deformation of the lifting member 40 and improve the rotational stability of the lifting member 40.

[0096] In some embodiments, refer to Figure 3 , the outer peripheral side surface of the force-receiving portion 43 is configured as the outer peripheral side surface of a hexagonal nut. In this way, an operator can cooperate a wrench with the force-receiving portion 43 to drive the rotation of the force-receiving portion 43, and then drive the rotation between the threaded portion 42 of the lifting member 40 and the first threaded hole K1, so that the second end portion 23 moves along the length direction of the lifting member 40 and approaches or moves away from the first end portion 13.

[0097] In some embodiments, refer to Figure 5, the distance between the pressing part 21 and the second connecting part 22 is L1, and the distance between the second end part 23 and the second connecting part 22 is L2, where L1 < L2. In this way, a labor-saving lever structure is formed between the pressing member 20 and the adjusting assembly 30. On the premise that the first target member 200 is subjected to the same force, the force that the operator needs to apply to the second end part 23 is reduced, thereby improving the operation convenience of the operator and enhancing the user experience. In other embodiments, when the disassembly and assembly space of the disassembly device 100 is small, the relationship between L1 and L2 can also be set as L1 ≥ L2.

[0098] In some embodiments, referring to Figure 4 and Figure 5 , the adjusting assembly 30 includes an adjusting rod 31 and a pin shaft 32. One end of the adjusting rod 31 is movably connected to the first connecting part 12, and the other end of the adjusting rod 31 is rotatably connected to the second connecting part 22 through the pin shaft 32. In this way, the rotational connection between the adjusting assembly 30 and the second connecting part 22 is realized.

[0099] In some embodiments, referring to Figure 4 , a rotating hole K4 penetrating along the second direction Y is formed in the second connecting part 22. The length direction of the pin shaft 32 is parallel to the second direction Y, and the pin shaft 32 extends into the rotating hole K4 so that the second connecting part 22 can rotate relative to the pin shaft 32.

[0100] In some embodiments, referring to Figure 4 , a second threaded hole K2 is formed in the first connecting part 12, and the adjusting rod 31 is threadedly connected to the second threaded hole K2. In this way, stepless connection between the adjusting rod 31 and the second connecting part 22 can be realized. By screwing the adjusting rod 31 into and out of the second threaded hole K2, the position of the second connecting part 22 on the adjusting rod 31 can be adjusted, thereby adjusting the distance between the second connecting part 22 and the first connecting part 12 to meet the disassembly and assembly requirements of the first target member 200 and the second target member 300 with different sizes. In addition, the threaded connection between the adjusting rod 31 and the second threaded hole K2 also has a self-locking function to ensure that the first connecting part 12 and the second connecting part 22 will not move closer to or away from each other along the first direction under the drive of the lifting member 40 during the use of the disassembly device 100.

[0101] In other embodiments, the second connecting part 22 and the adjusting assembly 30 can also be connected in a position-adjustable manner by other means. For example, a number of fastening holes are provided on the adjusting assembly 30 along its length direction. When the second connecting part 22 is connected to different fastening holes, the distance between the second connecting part 22 and the first connecting part 12 is also different. In this way, the distance between the first connecting part 12 and the second connecting part 22 can be adjusted by adjusting the position of the second connecting part 22.

[0102] In some embodiments, referring to Figure 6, the disassembly device 100 further includes an elastic member 50, and the elastic member 50 elastically abuts between the adjustment assembly 30 and the base member 10. The elastic member 50 can be set as an elastic structure such as a torsion spring, a tension spring, an elastic column, etc. The elastic member 50 can apply an elastic force to the first connection portion 12, so that the second connection portion 22 is not easily rotated relative to the adjustment assembly 30, improving the connection stability between the second connection portion 22 and the adjustment assembly 30. Furthermore, during the disassembly and assembly process of the disassembly device 100, the distance between the first connection portion 12 and the second connection portion 22 can be kept stable and unchanged. In addition, during the position adjustment process of the base member 10 on the adjustment assembly 30, the elastic force (i.e., the damping force) applied by the elastic member 50 can also improve the position adjustment experience of the base member 10.

[0103] In some embodiments, referring to Figure 6 , the adjustment assembly 30 further includes a flange 33. The flange 33 protrudes from the outer peripheral surface of the adjustment rod 31. The elastic member 50 elastically abuts between the flange 33 and the first connection portion 12. In this way, the stable installation of the elastic member 50 is realized.

[0104] In some embodiments, referring to Figure 5 and Figure 6 , the second connection portion 22 is provided with a receiving hole K3. The adjustment rod 31 extends into the receiving hole K3, and there is a gap between the circumferential side surface of the adjustment rod 31 and the hole surface of the receiving hole K3, so that the pressing member 20 can rotate relative to the pin shaft 32, and the distance between the fixing portion 11 and the pressing portion 21 can float within a preset range. Among them, the preset range can be set within 10 mm along the first direction X. In other embodiments, the value of the preset range can be adjusted according to the gap size between the receiving hole K3 and the adjustment rod 31. In this way, it can be ensured that the pressing member 20 can rotate relative to the adjustment rod 31 after being stressed, avoiding the pressing member 20 from being stuck and ensuring the normal operation of the disassembly device 100. In some embodiments, the receiving hole K3 penetrates through the second connection portion 22 along the first direction X to facilitate the installation between the adjustment rod 31 and the second connection portion 22.

[0105] In some embodiments, referring to Figure 5, the accommodating hole K3 has a first side surface P2 and a second side surface P3 which are arranged opposite to each other along the third direction Z. When the first side surface P2 abuts against the adjusting rod 31, the pressing member 20 is in the first position; when the second side surface P3 abuts against the adjusting rod 31, the pressing member 20 is in the second position, and the distance between the pressing portion 21 of the pressing member 20 located at the first position and the pressing portion 21 located at the second position is the value of the preset range, which is also the moving stroke of the pressing portion 21. Therefore, the gap between the adjusting rod 31 and the hole surface of the accommodating hole K3 can control the moving stroke of the pressing portion 21, so as to meet different disassembly requirements. For example, when the first target part 200 needs to be completely disengaged from the second target part 300 by the disassembly device 100, the moving stroke of the pressing portion 21 can be increased by increasing the gap, and when the disassembly device 100 only needs to form a gap between the first target part 200 and the receiving hole 400, the moving stroke of the pressing portion 21 can be reduced by reducing the gap.

[0106] In some embodiments, see Figure 5 The cross section of the adjusting rod 31 along the direction perpendicular to the first direction X is circular, and the cross section of the accommodating hole K3 along the direction perpendicular to the first direction X is rectangular. In this way, a gap is ensured between the adjusting rod 31 and the hole surface of the accommodating hole K3, and a larger rotation space can be provided for the second connecting portion 22 to rotate relative to the adjusting rod 31.

[0107] In other embodiments, the shape of the end of the adjusting rod 31 along the cross section perpendicular to the first direction X is circular, and the shape of the accommodating hole K3 along the cross section perpendicular to the first direction X is fan-ring shaped. The fan-ring shaped accommodating hole K3 can provide a larger rotation range for the adjusting rod 31 to further increase the moving stroke of the pressing portion 21 of the disassembly device 100, thereby increasing the applicability of the disassembly device 100.

[0108] In some embodiments, see Figure 5 The pin 32 passes through the second connection part 22 along the second direction Y and passes through the adjustment rod 31 in the accommodation hole K3, so that the pressing member 20 can rotate relative to the adjustment assembly 30 through the pin 32. In other embodiments, the pin 32 can also be fixedly connected to the adjustment rod 31, and a rotation groove formed by a depression is provided on the side of the second connection part 22 away from the first connection part 12, and the pin 32 is matched in the rotation groove, so that the pressing member 20 can also rotate around the pin 32.

Although the present application has been described in detail with reference to the above preferred implementation modes, a person skilled in the art should understand that the technical solutions of the present application may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present application.
