[0002] A hinge structure is used to connect multiple parts, allowing the parts to rotate relative to each other.

[0003] However, in the production of hinges in related technologies, it is difficult to align the hinge joints with the locking pins, which makes the hinges prone to damage. Utility Model Content

[0004] The purpose of this application is to at least solve the problem of the difficulty in aligning and locking the hinge joint in related technologies. This purpose is achieved through the following means: The first aspect of this application provides a hinge mounting fixture, including a first positioning member and a second positioning member. The second positioning member is movably disposed on the first positioning member and has a pressing position and a releasing position relative to the first positioning member. At least a portion of the second positioning member in the pressing position is opposite to the first positioning member and is configured to press the hinge with the first positioning member. The second positioning member in the releasing position is configured to be detached from the hinge.

[0005] The hinge mounting fixture of this application, when locking the hinge, pre-shapes the hinge and places it in a suitable position on the first positioning member, drives the second positioning member to move to the pressing position, and at least a portion of the second positioning member presses the hinge against the first positioning member, thereby pre-shaping the hinge and reducing the difficulty of locking the hinge joint. During the hinge locking process, the pressing action of the first and second positioning members can partially or completely offset the force of the pin on the hinge, making the hinge joint less prone to misalignment, thereby further reducing the difficulty of locking the hinge joint.

[0006] In some embodiments, the first positioning member includes a first abutment portion for abutting against one end of the hinge, and the second positioning member includes a second abutment portion. When the second positioning member is in the pressed position, the second abutment portion is opposite to the first abutment portion in a first direction and is configured to press against the hinge from the other end of the hinge.

Both the first clearance hole and the second clearance hole are used to avoid the second closing joint of the hinge. The second closing joint is formed by connecting the end of at least one hinge arm and the middle portion of at least another hinge arm in the hinge. The first clearance hole and the second clearance hole penetrate the second abutment portion along the first direction. Along the third direction, the end of the first clearance hole and the second clearance hole away from the moving portion is open, and the inner wall of the end of the first clearance hole and the second clearance hole near the moving portion extends around the first direction.

[0012] In some embodiments, the first abutment portion is provided with a first mounting groove, a second mounting groove, a third clearance hole, and a fourth clearance hole.

[0019] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “described” as used herein may also include the plural forms. The terms “comprising,” “including,” “containing,” and “having” are inclusive and therefore indicate the presence of the stated features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0024] A hinge structure is used to connect multiple parts, allowing the parts to rotate relative to each other.

[0025] However, in the production of hinges in related technologies, it is difficult to align the hinge joints with the locking pins, which makes the hinges prone to damage.

[0026] In order to at least solve the problem of the difficulty in aligning and locking the hinge joint in the related technology, the embodiments of this application propose a hinge mounting fixture 100, which can press the pre-assembled hinge together, thereby reducing the difficulty of locking the hinge joint.

[0027] Embodiments of this application also propose a pinning device including the hinge mounting fixture 100 as described above.

[0028] The hinge mounting fixture 100 and the pinning device according to embodiments of this application are described below with reference to the accompanying drawings.

[0029] Combination Figures 1 to 7 As shown, the hinge mounting fixture 100 of this application embodiment includes a first positioning member 10 and a second positioning member 20. The second positioning member 20 is movably disposed on the first positioning member 10 and has a pressing position and a releasing position relative to the first positioning member 10. At least a portion of the second positioning member 20 in the pressing position is opposite to the first positioning member 10 and is configured to press the hinge 200 with the first positioning member 10. The second positioning member 20 in the releasing position is configured to be able to separate from the hinge 200.

[0030] It should be noted that the pressing position can be one location or multiple locations. The releasing position can also be one location or multiple locations.

[0031] When locking the hinge 200, the hinge 200 is pre-shaped and placed in a suitable position on the first positioning member 10. The second positioning member 20 is then driven to move to the pressing position, where at least a portion of the second positioning member 200 presses against the first positioning member 10, thus pre-shaping the hinge 200 and reducing the difficulty of locking the hinge 200's closing joint. During the locking process, the pressing action of the first positioning member 10 and the second positioning member 20 can partially or completely offset the force of the pin on the hinge 200, making the hinge 200's closing joint less prone to misalignment, thereby further reducing the difficulty of locking the hinge 200's closing joint.

[0032] When hinge 200 finishes locking, it drives the second positioning member 20 to move to the release position, and the second positioning member 20 separates from hinge 200, so that hinge 200 can be removed.

[0033] In some specific embodiments, the hinge 200 is connected by knurled pins.

[0034] The knurling of the knurled pin can create a tightening effect with the hole wall of the hinge 200's retractable joint, allowing the hinge 200 to be connected more stably.

[0035] During the pinning process of hinge 200, the pressing action of the first positioning member 10 and the second positioning member 20 can partially or completely offset the force of the knurled pin on hinge 200, making it less likely for the hinge 200 to misalign, thereby further reducing the difficulty of pinning hinge 200.

[0036] Combination Figures 1 to 6 As shown, in some embodiments, the first positioning member 10 includes a first abutting portion 11 for abutting one end of the hinge 200, and the second positioning member 20 includes a second abutting portion 21. When the second positioning member 20 is in the pressed position, the second abutting portion 21 is opposite to the first abutting portion 11 along a first direction a and is configured to press against the hinge 200 from the other end of the hinge 200. When the second positioning member 20 is in the released position, the second abutting portion 21 is offset from the first abutting portion 11 and is configured to be able to separate from the hinge 200.

[0037] As an example, in the first direction a, such as Figure 1 , Figure 2 and Figure 4 As indicated by the arrow at point a. As some preferred examples, the first direction a is the thickness direction of the first abutment portion 11. As other preferred examples, the first direction a is the thickness direction of the second abutment portion 21.

[0038] The first abutting part 11 abuts against one end of the hinge 200. When the second positioning member 20 is in the pressed position, the second abutting part 21 presses against the hinge 200 from the other end of the hinge 200. The hinge 200 is pressed together by the combined action of the first abutting part 11 and the second abutting part 21. Through the opposing cooperation of the first abutting part 11 and the second abutting part 21, the hinge 200 can be restricted, thereby reducing the difficulty of locking the hinge 200's closing joint.

[0039] The second abutting part 21 is misaligned with the first abutting part 11. This means that the second abutting part 21 and the first abutting part 11 are misaligned. It can be that a part of the second abutting part 21 is opposite to the first abutting part 11, while another part of the second abutting part 21 is misaligned with the first abutting part 11. Alternatively, the second abutting part 21 and the first abutting part 11 are not opposite to each other at all.

[0040] When the second positioning member 20 is in the released position, the second abutment part 21 is offset from the first abutment part 11, so that the second abutment part 21 can be separated from the hinge 200, thereby making enough space for the removal and placement of the hinge 200.

[0041] In some optional embodiments, the second positioning member 20 is movably disposed on the first positioning member 10 along the first direction a, at least a portion of the second positioning member 20 is disposed opposite to the first positioning member 10 along the first direction a, at least a portion of the second positioning member 20 in the pressing position abuts against the first positioning member 10 together and presses the hinge 200 along the first direction a, and the second positioning member 20 in the releasing position is separated from the hinge 200.

[0042] When in the pressed position, the second positioning member 20 is positioned relatively close to the first positioning member 10 along the first direction a. At least a portion of the second positioning member 20 and the first positioning member 10 abut against the hinge 200, forming a pressing effect on the hinge 200. When in the released position, the second positioning member 20 separates from the hinge 200.

[0043] By movably positioning the second positioning member 20 on the first positioning member 10 along the first direction a, the pressing force can be concentrated in the first direction a, thereby improving the pressing effect on the hinge 200.

[0044] When the hinge arm is being engaged, the end of the hinge arm is not very stable, which makes the retraction joint formed at the end of the hinge arm prone to misalignment, thus making it more difficult to engage the hinge arm.

[0045] Therefore, in combination Figure 1 , Figure 6 and Figure 7As shown, in some embodiments, the second abutment portion 21 is provided with a first clearance groove 211, which extends through the second abutment portion 21 along a first direction a. The first clearance groove 211 is located between the two ends of the second abutment portion 21 along a second direction b, where the first direction a and the second direction b are perpendicular. The first clearance groove 211 is used to avoid the first retraction joint 210 of the hinge 200, which is formed by connecting the ends of at least two hinge arms in the hinge 200. The hinge 200 may have one first retraction joint 210 or multiple second retraction joints 220.

[0046] The first clearance groove 211 can avoid the first retractable joint 210, thereby preventing the second abutment part 21 from interfering with the pin, and thus allowing the pin to be driven into the first retractable joint 210.

[0047] By placing the first clearance groove 211 between the two ends of the second abutment portion 21 along the second direction b, the portions of the second abutment portion 21 on both sides of the first clearance groove 211 can fully contact the hinge portions 200 on both sides of the first retractable joint 210, thereby reducing the probability of misalignment of the first retractable joint 210 and thus reducing the difficulty of disengaging the first retractable joint 210.

[0048] Combination Figure 1 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, in some embodiments, the first abutment portion 11 is provided with a second clearance groove 111. The second clearance groove 111 passes through the first abutment portion 11 along the first direction a and is used to avoid the first closing joint 210 of the hinge 200. The second clearance groove 111 is located between the two ends of the first abutment portion 11 along the second direction b. When the second positioning member 20 is in the pressing position, the first clearance groove 211 and the second clearance groove 111 correspond along the first direction a.

[0049] The second clearance groove 111 can further avoid the first retractable joint 210, thereby preventing the first abutment part 11 from interfering with the pin, and thus reducing the difficulty of removing the pin from the first retractable joint 210.

[0050] By placing the second clearance groove 111 between the two ends of the second abutment portion 21 along the second direction b, the portions of the second abutment portion 21 on both sides of the first clearance groove 211 can fully contact the hinge portions 200 on both sides of the first retractable joint 210, thereby reducing the probability of misalignment of the first retractable joint 210 and thus reducing the difficulty of disengaging the first retractable joint 210.

[0051] Combination Figures 1 to 5As shown, in some embodiments, the first positioning member 10 includes a mounting portion 12 connected to the first abutting portion 11 along a third direction c, and the second positioning member 20 includes a moving portion 22 connected to the second abutting portion 21 along a third direction c. The moving portion 22 is movably disposed on the mounting portion 12 along the third direction c, and the first direction a, the second direction b and the third direction c are perpendicular to each other.

[0052] By movably providing the motion part 22 along the third direction c to the mounting part 12, the ineffective movement of the motion part 22 can be reduced, and the motion part 22 can efficiently drive the second abutment part 21 to switch between the pressing position and the releasing position.

[0053] The first positioning member 10 and the second positioning member 20 are moved by the mounting part 12 and the moving part 22, and the first abutting part 11 and the second abutting part 21 are pressed together by the first positioning member 10 and the second positioning member 20. This avoids interference between the moving and pressing structures of the first positioning member 10 and the second positioning member 20, thereby increasing the structural rationality of the first positioning member 10 and the second positioning member 20.

[0054] In some specific embodiments, the first abutting part 11 and the mounting part 12 are integrally formed and connected.

[0055] The first abutting part 11 and the mounting part 12 are integrally formed and connected, which can eliminate the splicing gap between the first abutting part 11 and the mounting part 12, and reduce the weak position between the first abutting part 11 and the mounting part 12, thereby improving the structural strength of the first positioning member 10 and increasing the service life of the first positioning member 10.

[0056] In some specific embodiments, the second contact portion 21 and the moving portion 22 are integrally formed and connected.

[0057] The second abutment portion 21 and the moving portion 22 are integrally formed and connected, which can eliminate the splicing gap between the second abutment portion 21 and the moving portion 22, and reduce the weak points between the second abutment portion 21 and the moving portion 22, thereby improving the structural strength of the second positioning member 20 and increasing the service life of the second positioning member 20.

[0058] Combination Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, in some embodiments, when the second positioning member 20 is in the pressed position, the second abutting portion 21 is spaced apart from the first abutting portion 11 along the first direction a.

[0059] When the second positioning member 20 moves from the release position to the pressing position, the second abutting part 21 is spaced apart from the first abutting part 11 along the first direction a, which can reduce the resistance when the second abutting part 21 contacts the hinge 200, so that the second abutting part 21 can smoothly contact the hinge 200 and press against the hinge.

[0060] Combination Figure 1 , Figure 6 and Figure 7 As shown, in some embodiments, the first clearance groove 211 extends along a third direction c, and along the third direction c, the end of the first clearance groove 211 away from the moving part 22 is open, and the inner wall of the end of the first clearance groove 211 near the moving part 22 extends around a first direction a.

[0061] Along the third direction c, the end of the first clearance groove 211 away from the moving part 22 is open. When the second positioning member 20 moves from the release position to the pressing position, it can prevent the end of the first clearance groove 211 away from the moving part 22 from rubbing against the hinge 200, thereby reducing the difficulty of the second positioning member 20 moving from the release position to the pressing position, so that the second abutment part 21 can smoothly contact the hinge 200 and press against the hinge.

[0062] Along the third direction c, the inner wall of the first clearance groove 211 near the moving part 22 extends around the first direction a. That is, along the third direction c, the inner wall surface of the first clearance groove 211 near the moving part 22 is curved. This makes the shape of the end of the first clearance groove 211 near the moving part 22 match the shape of the pin hole of the hinge 200, thereby improving the clearance effect of the first clearance groove 211 on the first retracting joint 210. In addition, by making the inner wall surface of the first clearance groove 211 near the moving part 22 curved, the stress concentration of the inner wall of the first clearance groove 211 can also be reduced, thereby increasing the service life of the second positioning member 20.

[0063] Combination Figure 1 , Figure 6 and Figure 7 As shown, in some embodiments, the second clearance groove 111 extends along a third direction c, and along the third direction c, the end of the second clearance groove 111 away from the mounting portion 12 is open, and the inner wall of the end of the second clearance groove 111 near the mounting portion 12 extends around a first direction a.

[0064] Along the third direction c, the end of the second clearance groove 111 away from the mounting part 12 is open, which can reduce the probability of the end of the second clearance groove 111 away from the mounting part 12 interfering with the hinge 200, thereby increasing the structural rationality of the first abutment part 11.

[0065] Along the third direction c, the inner wall of the second clearance groove 111 near the mounting portion 12 extends around the first direction a. That is, along the third direction c, the inner wall surface of the second clearance groove 111 near the mounting portion 12 is curved. This allows the shape of the end of the second clearance groove 111 near the mounting portion 12 to match the shape of the pin hole of the hinge 200, thereby improving the clearance effect of the second clearance groove 111 on the first retractable joint 210. Furthermore, by making the inner wall surface of the second clearance groove 111 near the moving portion 22 curved, the stress concentration on the inner wall of the second clearance groove 111 can be reduced, thereby increasing the service life of the first positioning member 10.

[0066] Combination Figure 1 , Figure 6 and Figure 7 As shown, in some specific embodiments, along the third direction c, the inner wall of the first clearance groove 211 at the end away from the moving part 22 is provided with a rounded corner.

[0067] By rounding the corners, the inner wall surface of the first clearance groove 211 near the moving part 22 along the third direction c is made curved, so that the shape of the first clearance groove 211 near the moving part 22 is adapted to the shape of the pin hole of the hinge 200, thereby improving the clearance effect of the first clearance groove 211 on the first retracting joint 210. In addition, it can also reduce the stress concentration on the inner wall of the first clearance groove 211, thereby reducing the risk of stress damage to the second positioning member 20.

[0068] Combination Figure 1 , Figure 6 and Figure 7 As shown, in some specific embodiments, along the third direction c, the inner wall of the second clearance groove 111 at the end away from the mounting part 12 is provided with a rounded corner.

[0069] By rounding the corners, the inner wall surface of the second clearance groove 111 near the mounting part 12 along the third direction c is made curved, so that the shape of the end of the second clearance groove 111 near the mounting part 12 is adapted to the shape of the pin hole of the hinge 200, thereby improving the clearance effect of the second clearance groove 111 on the first retractable joint 210. Moreover, by making the inner wall surface of the second clearance groove 111 near the moving part 22 curved, the stress concentration of the inner wall of the second clearance groove 111 can also be reduced, thereby reducing the risk of stress damage to the first positioning member 10.

[0070] Combination Figure 1 , Figure 6 and Figure 7As shown, in some embodiments, the second abutment portion 21 is further provided with a first clearance hole 212 and a second clearance hole 213. The first clearance hole 212 is provided at one end of the second abutment portion 21 along the second direction b, and the second clearance hole 213 is provided at the other end of the second abutment portion 21 along the second direction b. Both the first clearance hole 212 and the second clearance hole 213 are used to avoid the second retraction joint 220 of the hinge 200. The second retraction joint 220 is formed by connecting the end of at least one hinge arm and the middle portion of at least another hinge arm in the hinge 200. The hinge 200 may have one second retraction joint 220 or multiple second retraction joints 220.

[0071] The second retractable joint 220 can be avoided by the first clearance hole 212 and the second clearance hole 213, thereby preventing the second abutment part 21 from interfering with the pin, and thus allowing the pin to be driven into the second retractable joint 220.

[0072] The first clearance hole 212 and the second clearance hole 213 penetrate the second abutment portion 21 along the first direction a. Along the third direction c, the ends of the first clearance hole 212 and the second clearance hole 213 away from the moving portion 22 are open. The inner walls of the ends of the first clearance hole 212 and the second clearance hole 213 near the moving portion 22 extend around the first direction a.

[0073] The second retractable joint 220 is formed by connecting the end of at least one hinge arm of the hinge 200 and the middle portion of at least another hinge arm. The middle portion of the hinge arm is located between the two ends of the hinge arm, and is relatively stable compared to the end of the hinge arm. Therefore, the second retractable joint 220 is relatively easy to engage. A first clearance hole 212 is provided at one end of the second abutment portion 21 along the second direction b, and a second clearance hole 213 is provided at the other end of the second abutment portion 21 along the second direction b, which can meet the pressing requirements when the second retractable joint 220 is engaged.

[0074] Along the third direction c, the ends of the first clearance hole 212 and the second clearance hole 213 away from the moving part 22 are open. When the second positioning member 20 moves from the release position to the pressing position, it can prevent the end of the first clearance hole 212 away from the moving part 22 from rubbing against the hinge 200, and it can also prevent the end of the second clearance hole 213 away from the moving part 22 from rubbing against the hinge 200. This reduces the difficulty of the second positioning member 20 moving from the release position to the pressing position, so that the second abutting part 21 can smoothly disengage from the hinge 200 and press against the hinge 200.

[0075] Along the third direction c, the inner walls of the first clearance hole 212 and the second clearance hole 213 near the moving part 22 extend around the first direction a. That is, along the third direction c, the end of the first clearance hole 212 near the moving part 22 is curved, and the end of the second clearance hole 213 near the moving part 22 is also curved. This ensures that the shapes of the ends of the first clearance hole 212 and the second clearance hole 213 near the moving part 22 are adapted to the shape of the pin hole, thereby improving the clearance effect of the first clearance hole 212 and the second clearance hole 213 on the second retractable joint 220. Furthermore, the curved end of the first clearance hole 212 near the moving part 22 reduces stress concentration in the first clearance hole 212, and the curved end of the second clearance hole 213 near the moving part 22 reduces stress concentration in the second clearance hole 213, thereby reducing the risk of stress-induced damage to the first positioning member 10.

[0076] Combination Figure 1 , Figure 6 and Figure 7 As shown, in some specific embodiments, along the second direction b, the end of the first clearance hole 212 facing away from the first clearance groove 211 is open.

[0077] Along the second direction b, the end of the first clearance hole 212 facing away from the first clearance groove 211 is open. When the second positioning member 20 moves from the release position to the pressing position, it can prevent the end of the first clearance hole 212 facing away from the first clearance groove 211 from rubbing against the hinge 200. This reduces the difficulty of the second positioning member 20 moving from the release position to the pressing position, allowing the second abutting part 21 to smoothly disengage from the hinge 200 and press against the hinge 200.

[0078] Combination Figure 1 , Figure 6 and Figure 7 As shown, in some specific embodiments, along the second direction b, the end of the second clearance hole 213 facing away from the first clearance groove 211 is open.

[0079] Along the second direction b, the end of the second clearance hole 213 facing away from the first clearance groove 211 is open. When the second positioning member 20 moves from the release position to the pressing position, it can prevent the end of the second clearance hole 213 facing away from the first clearance groove 211 from rubbing against the hinge 200. This reduces the difficulty of the second positioning member 20 moving from the release position to the pressing position, allowing the second abutment part 21 to smoothly disengage from the hinge 200 and press against the hinge 200.

[0080] Combination Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, in some embodiments, the first abutment portion 11 is provided with a first mounting groove 112, a second mounting groove 113, a third clearance hole 114 and a fourth clearance hole 115. The first mounting groove 112 and the second mounting groove 113 are both used to mount the hinge 200, and the extending directions of the first mounting groove 112 and the second mounting groove 113 intersect.

[0081] The third clearance hole 114 passes through the first abutment portion 11 along the first direction a and communicates with the first mounting groove 112. The fourth clearance hole 115 passes through the second abutment portion 21 along the first direction a and communicates with the second mounting groove 113. Both the third clearance hole 114 and the fourth clearance hole 115 are used to avoid the second retracting joint 220 of the hinge 200. When the second positioning member 20 is in the pressing position, the first clearance hole 212 and the third clearance hole 114 are opposite to each other, and the second clearance hole 213 and the fourth clearance hole 115 are opposite to each other.

[0082] When the first abutting part 11 and the second abutting part 21 press against the hinge 200, both the first mounting groove 112 and the second mounting groove 113 can limit the hinge 200, thereby increasing the pressing effect of the first abutting part 11 and the second abutting part 21 on the hinge 200.

[0083] The first mounting groove 112 and the second mounting groove 113 can also pre-install the hinge 200. When the second positioning member 20 moves from the release position to the pressing position, the first mounting groove 112 and the second mounting groove 113 can reduce the probability of misalignment of the hinge 200.

[0084] The third clearance hole 114 and the fourth clearance hole 115 can further avoid the first retractable joint 210, thereby preventing the first abutment part 11 from interfering with the pin, and thus reducing the difficulty of removing the pin from the first retractable joint 210.

[0085] Combination Figure 4 and Figure 5 As shown, in some embodiments, one of the mounting part 12 and the moving part 22 is provided with a slider 221, and the other of the mounting part 12 and the moving part 22 is provided with a groove 121 extending along a third direction c, and the slider 221 is slidably disposed in the groove 121.

[0086] The slide groove 121 extends along the third direction c, and the slider 221 is disposed in the slide groove 121. Through the cooperation of the slider 221 and the slide groove 121, the movement of the second positioning member 20 can be guided, thereby making the movement of the second positioning member 20 more accurate.

[0087] Combination Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, in some specific embodiments, the slider 221 is provided with a guide groove 222, and a guide member 122 is provided in the groove 121. The guide groove 222 extends along a third direction c, and the guide member 122 is slidably disposed in the guide groove 222.

[0088] The guide groove 222 extends along the third direction c, and the guide member 122 is disposed in the guide groove 222. Through the cooperation of the guide groove 222 and the guide member 122, the movement of the second positioning member 20 can be further guided, thereby further increasing the movement accuracy of the second positioning member 20.

[0089] Combination Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, in some specific embodiments, when the second positioning member 20 is in the pressing position, the inner wall of one end of the guide groove 222 along the third direction c abuts against the guide member 122; when the second positioning member 20 is in the contact position, the inner wall of the other end of the guide groove 222 along the third direction c abuts against the guide member 122.

[0090] The movement of the second positioning member 20 can be restricted by the cooperation of the guide groove 222 and the guide member 122, so as to avoid excessive movement of the second positioning member 20.

[0091] Combination Figures 1 to 7 In some embodiments, the hinge mounting fixture 100 further includes a handle 30, which is located on the side of the moving part 22 away from the second abutment part 21 along the third direction c and is connected to the second abutment part 21.

[0092] The handle 30 provides a direct and convenient point of force application for the drive motion unit 22, thereby reducing the difficulty of driving the handle 30 to move.

[0093] The pin-removing device of this application embodiment includes the hinge mounting fixture 100 as described in the above embodiment. When pinning the hinge 200, the hinge 200 is pre-shaped and placed at a suitable position on the first positioning member 10. The second positioning member 20 is driven to move to the pressing position, where at least a portion of the second positioning member 20 presses against the first positioning member 10 to engage the hinge 200, thereby pre-shaping the hinge 200 and reducing the difficulty of pinning the hinge 200's closing joint. During the pinning process, the pressing action of the first positioning member 10 and the second positioning member 20 can partially or completely offset the force of the pin on the hinge 200, making the hinge 200's closing joint less prone to misalignment, thereby further reducing the difficulty of pinning the hinge 200's closing joint. Therefore, the pin-removing device of this application embodiment can reduce the difficulty of pinning the hinge's closing joint.

[0094] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
