Description

Technical Field

[0001] The utility model relates to the technical field of vehicle-mounted article brackets, in particular to an article clamping mechanism. Background Art

[0002] At present, mobile phone wireless charging technology has been widely used in vehicles. Since vehicles are in motion most of the time, it is easy for the mobile phone to detach from the wireless charging module, affecting the charging efficiency. A clamping mechanism is needed to clamp and fix the mobile phone.

[0003] Chinese utility model patent CN220701032U discloses a vehicle-mounted clamping device, including: a container box for embedding in the interior structure of an automobile, the top of the container box is open to form an opening for inserting objects to be placed, the opening is exposed to the surface of the interior structure of the automobile when the container box is embedded, and the front wall of the container box is provided with a movable opening; a clamping member, which is inserted into the container box through the movable opening and cooperates with the rear wall of the container box to form a clamping channel for clamping objects. The first arm and the second arm of the device form a two-link rod. If the raised structures such as the camera and the step surface of the protective shell on the mobile phone are located at the bottom and inserted downward into the container box, when the mobile phone is taken out, the force direction at the intersection of the raised structure of the mobile phone and the clamping member of the two-link rod is opposite to the rotation direction of the clamping member, which easily causes the clamping member to enter a self-locking state, thereby causing the mobile phone to get stuck when it is taken out, and the use scenario is limited.

[0004] In addition to wireless charging of mobile phones, there are also other object clamping requirements, such as pads, books, medicine boxes, wallets, etc. The existing vehicle-mounted clamping device cannot meet the requirements of clamping other objects except mobile phones. Therefore, it is necessary to provide an object clamping mechanism that can solve the problem that the clamping mechanism in the existing technology is easy to get stuck during the object removal process. Utility Model Content

[0005] In view of the above situation, the utility model provides an article clamping mechanism, which can solve the problem in the prior art that the clamping mechanism is easily stuck during the process of taking out the article.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is: an article clamping mechanism, comprising:

[0007] A shell, the side wall of the shell surrounds a cavity for accommodating the article, and an opening is formed on the side wall; and

[0008] A three-link structure movably mounted on the opening;

[0009] The three-link structure comprises an upper link and a lower link movably connected to the housing, and a synchronization rod movably connected to the upper link and the lower link respectively;

[0010] The synchronization rod is configured to move synchronously with the upper connecting rod when the object is inserted into the cavity, and to rotate relative to the upper connecting rod when the object is taken out of the cavity.

[0011] In an embodiment of the utility model, a first rotating part and a second rotating part are formed on the upper connecting rod, a third rotating part is formed on the synchronization rod, the upper connecting rod is rotatably connected to the shell through the first rotating part via the first rotating member, and the upper connecting rod is rotatably connected to the third rotating part through the second rotating part via the second rotating member.

[0012] In an embodiment of the utility model, a second limiting surface is formed on the upper connecting rod, and a third limiting surface is formed on the third rotating part; when the object is inserted into the cavity, the second limiting surface and the third limiting surface fit together, so that the synchronization rod and the upper connecting rod rotate synchronously; when the object is taken out of the cavity, the second limiting surface and the third limiting surface separate from each other, so that the upper connecting rod and the synchronization rod rotate relative to each other.

[0013] In an embodiment of the utility model, a rotating surface is formed on the third rotating portion adjacent to the third limiting surface. When the object is taken out of the cavity, the rotating surface rotates relative to the second limiting surface, causing the synchronization rod and the upper connecting rod to rotate relatively.

[0014] In an embodiment of the utility model, a channel is formed between the first rotating part and the second rotating part of the upper connecting rod, and a flange portion is formed on the synchronization rod. When the synchronization rod and the upper connecting rod rotate relative to each other, the flange portion can extend into the channel.

[0015] In an embodiment of the utility model, a first limiting surface is formed on the upper connecting rod; when the object is inserted into the cavity, the upper connecting rod rotates relative to the shell so that the first limiting surface is away from the side wall of the shell; when the object is taken out of the cavity, the first limiting surface abuts against the side wall of the shell to limit the upper connecting rod.

[0016] In an embodiment of the utility model, a first elastic member is provided between the upper connecting rod and the shell. When the object is inserted into the cavity, the object pushes the upper connecting rod and the synchronization rod to rotate synchronously, and the first elastic member is compressed to apply a clamping force to the object.

[0017] In an embodiment of the utility model, the first elastic member is configured as a first torsion spring sleeved on the first rotating member, one end of the first torsion spring abuts against the side wall of the shell, and the other end of the first torsion spring abuts against the upper connecting rod, so that the upper connecting rod can abut against the shell through the first torsion spring.

[0018] In an embodiment of the utility model, a second elastic member is provided between the upper connecting rod and the synchronization rod. When the object is inserted into the cavity, the second elastic member causes the synchronization rod to rotate synchronously with the upper connecting rod.

[0019] In an embodiment of the utility model, the second elastic member is configured as a second torsion spring sleeved on the second rotating member, and two ends of the second torsion spring are respectively abutted against the upper connecting rod and the synchronous rod.

[0020] In an embodiment of the utility model, the synchronization rod is pivotally connected to the lower connecting rod. After the object is inserted into the cavity, the pivot center of the synchronization rod and the lower connecting rod is not higher than the axis of the second rotating member.

[0021] In an embodiment of the utility model, a limiting portion is formed at the other end of the lower connecting rod, and a limiting sliding groove is formed on the side wall of the shell. The limiting portion can be slidably inserted in the limiting sliding groove, so that the other end of the lower connecting rod is movably connected to the shell.

[0022] The utility model adopts the above technical solution, so that it has the following beneficial effects:

[0023] (1) The utility model is provided with a three-link structure formed by an upper link, a synchronization rod and a lower link. During the stage of inserting an item, the synchronization rod and the upper link are kept relatively still and move synchronously through the fit of the second limit surface and the third limit surface. The first elastic member is transmitted to the item through the upper link and the synchronization rod to provide a clamping force for the item. During the stage of removing the item, the upper link is pressed against the shell through the first limit surface, the first elastic member unloads the force, and the synchronization rod rotates relative to the upper link through the rotational contact between the rotational surface and the second limit surface. During the rotation of the synchronization rod relative to the upper link, the second elastic member is compressed and provides a force to the item. Since the force provided by the second elastic member is smaller than the clamping force provided by the first elastic member, the item and its protruding structure can pass through the three-link structure smoothly. The rotation direction of the three-link structure is consistent with the movement direction of the item, and no obstruction is caused to the item, thereby ensuring the smooth removal of the item. The utility model has good adaptability to items of different models and specifications, and is not limited in usage scenarios.

[0024] (2) The utility model is provided with a synchronization rod and a lower connecting rod with an arc structure. The synchronization rod provides a first guiding arc surface when an object is inserted, and the lower connecting rod provides a second guiding arc surface when an object is taken out, thereby further ensuring that the insertion and removal of the object are easier and more labor-saving, and will not get stuck or scratch the object.

[0025] (3) The utility model provides a certain pressing force for the object through the first elastic member via the three-link structure, so that the object can be tightly attached to the inner wall of the shell and will not shake inside the shell or even fly out of the shell. It can be used in conjunction with the wireless charging module to ensure the effective charging of the object and its charging efficiency. It can also be expanded to various functional modules and can be flexibly installed in different positions in the car. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0042] To facilitate understanding of the present invention, the following description is provided in conjunction with the accompanying drawings and embodiments.

[0043] Please see attached Figure 1 To Attachment Figure 5 , an article clamping mechanism 100, comprising:

[0044] A housing 1, wherein the side wall of the housing 1 surrounds a cavity for accommodating the object 9, and an opening 11 is formed on the side wall; and

[0045] A three-link structure movably mounted on the opening 11;

[0046] The three-link structure comprises an upper link 2 and a lower link 4 movably connected to the housing 1, and a synchronization rod 3 movably connected to the upper link 2 and the lower link 4 respectively;

[0047] The synchronization rod 3 is configured to move synchronously with the upper connecting rod 2 when the object 9 is inserted into the cavity, and to rotate relative to the upper connecting rod 2 when the object 9 is taken out of the cavity.

[0048] The upper connecting rod 2, the synchronous rod 3 and the lower connecting rod 4 form a three-link structure. The synchronous rod 3 can move synchronously with the upper connecting rod 2 and move relative to the lower connecting rod 4 during the insertion stage of the object 9. The relative rotation of the synchronous rod 3 and the lower connecting rod 4 ensures that the object 9 is smoothly inserted into the cavity of the shell 1. At the same time, the synchronous rod 3 can rotate relative to the upper connecting rod 2 during the removal stage of the object 9, so that the lower connecting rod 4 has a larger range of motion relative to the two-link structure under the drive of the synchronous rod 3, avoiding interference with the object 9 and its protruding structures 901 such as the camera and the protective shell step, and ensuring that the object 9 is smoothly removed from the cavity.

[0049] According to usage requirements, the object 9 can be a mobile phone, a pad, a book, a medicine box, a wallet, etc. The shell 1 can be made according to the size adaptability of the object 9 so that it has a cavity that can accommodate the corresponding object 9.

[0050] Please see attached Figure 6 , Attachment Figure 8 and attached Fig. 9 The upper connecting rod 2 is formed with a first rotating portion 201 and a second rotating portion 202, and the synchronous rod 3 is formed with a third rotating portion 301. The upper connecting rod 2 is rotatably connected to the housing 1 via the first rotating portion 201 via the first rotating member 6, and the upper connecting rod 2 is rotatably connected to the third rotating portion 301 via the second rotating member 8 via the second rotating portion 202.

[0051] Preferably, both the first rotating member 6 and the second rotating member 8 can adopt rotating shafts, and the size of the rotating shafts can be adaptively selected according to actual installation requirements. The first rotating part 201 can adopt a perforated ear plate that matches the first rotating member 6, and the second rotating part 202 and the third rotating part 301 can adopt a perforated ear plate that matches the second rotating member 8, so that the rotation function of the upper connecting rod 2 relative to the shell 1 is guaranteed by the first rotating member 6, and the rotation function of the synchronization rod 3 relative to the upper connecting rod 2 is guaranteed by the second rotating member 8.

[0052] Preferably, the ear plates of the first rotating part 201, the second rotating part 202 and the third rotating part 301 are symmetrically arranged in pairs to ensure a smooth rotation process and uniform force.

[0053] Please see attached Figure 6 , Attachment Figure 8 and attached Fig. 9 The upper connecting rod 2 is formed with a second limiting surface 22, and the third rotating portion 301 is formed with a third limiting surface 31. The second limiting surface 22 and the third limiting surface 31 are both planar structures; the second limiting surface 22 and the third limiting surface 31 fit each other when the object 9 is inserted into the cavity, so that the upper connecting rod 2 and the synchronous rod 3 rotate synchronously, as shown in the attached Fig.10 and attached Fig.11 As shown in the figure, the second limiting surface 22 and the third limiting surface 31 separate from each other when the object 9 is taken out of the cavity, so that the upper connecting rod 2 and the synchronous rod 3 rotate relative to each other. Fig.12 To Attachment Fig.14 shown.

[0054] The second limiting surface 22 and the third limiting surface 31 can adopt an inclined surface structure, which can extend obliquely downward inside the shell 1. The inclined surface structure is used to limit the counterclockwise rotation of the second rotating member 8, so that the synchronization rod 3 and the upper connecting rod 2 only have a one-way relative rotation function.

[0055] As the object 9 is inserted downward, downward pressure is applied to the synchronization rod 3 and the counterclockwise rotation of the second rotating member 8 is restricted, the synchronization rod 3 is ensured to remain relatively stationary and move synchronously with the upper connecting rod 2 after being subjected to force during the insertion stage of the object 9.

[0056] Preferably, the second limiting surface 22 and the third limiting surface 31 are symmetrically arranged in pairs to ensure the abutment stability and movement synchronization of the upper connecting rod 2 and the synchronization rod 3.

[0057] Please see attached Figure 6 , Attachment Figure 8 and attached Fig. 9 The third rotating part 301 is formed with a rotating surface 32, which is an arc surface structure and is adjacent to the third limiting surface 31. The rotating surface 32 can rotate against the second limiting surface 22 when the object 9 is taken out of the cavity, so that the synchronization rod 3 rotates relative to the upper connecting rod 2 through the second rotating member 8 during the object 9 removal stage. Fig.12 To Attachment Fig.14 shown.

[0058] Preferably, along the clockwise rotation direction of the second rotating member 8, the rotating surface 32 is adjacent to the rear end of the third rotating portion 301 in the rotation direction, and the rotating surface 32 with an arc surface structure can play a guiding role, so that the synchronization rod 3 rotates clockwise relative to the upper connecting rod 2 through the second rotating member 8.

[0059] When the object 9 is taken out, an upward force is generated on the lower connecting rod 4 and transmitted to the synchronous rod 3, which can push the synchronous rod 3 to rotate clockwise relative to the upper connecting rod 2, thereby ensuring that the object 9 is smoothly taken out of the cavity.

[0060] Preferably, the rotating surfaces 32 are symmetrically arranged in pairs, so that the force during the relative rotation process of the synchronization rod 3 and the upper connecting rod 2 is balanced and stable; the length of the second limiting surface 22 can be consistent with the total length of the arc surface of the third limiting surface 31 and the rotating surface 32, ensuring the relative stillness and relative rotation of the synchronization rod 3 and the upper connecting rod 2.

[0061] Please see attached Figure 6 , Attachment Figure 8 and attached Fig. 9 A channel 23 is formed on the upper connecting rod 2 between the first rotating part 201 and the second rotating part 202, and a flange 33 is formed on the synchronization rod 3. When the synchronization rod 3 rotates relative to the upper connecting rod 2 through the second rotating member 8, the flange 33 can extend into the channel 23.

[0062] Through the provision of the channel 23, a gap is created between the synchronization rod 3 and the upper connecting rod 2, which affects the aesthetics of the structure; the channel 23 and the eaves 33 can be provided or cancelled according to actual needs.

[0063] Preferably, the width of the upper connecting rod 2 is slightly larger than the width of the opening 11, the width of the channel 23 is smaller than the width of the upper connecting rod 2, and the width of the synchronization rod 3 is slightly smaller than the width of the channel 23, ensuring that the abutment between the upper connecting rod 2 and the housing 1 and the rotation of the synchronization rod 3 are not hindered.

[0064] Please see attached Figure 1 , Attachment Figure 2 and attached Figure 6 A first limiting surface 21 is formed on the upper connecting rod 2; when the object 9 is inserted into the cavity, the upper connecting rod 2 rotates relative to the shell 1 so that the first limiting surface 21 is away from the side wall of the shell 1; when the object 9 is taken out of the cavity, the first limiting surface 21 abuts against the side wall of the shell 1 to limit the upper connecting rod 2.

[0065] Preferably, the first limiting surfaces 21 are symmetrically arranged in pairs, so that a pair of first limiting surfaces 21 abut against the outer wall of the shell 1 on both sides of the opening 11 to limit the rotation range of the upper connecting rod 2.

[0066] Please see attached Figure 1 , Attachment Figure 2 and attached Figure 6 A first elastic member is provided between the upper connecting rod 2 and the shell 1. When the object 9 is inserted into the cavity, the object 9 pushes the upper connecting rod 2 and the synchronization rod 3 to rotate synchronously, and the first elastic member is compressed to apply a clamping force to the object 9.

[0067] As a first preferred embodiment, the first elastic member is configured as a first torsion spring 5 sleeved on the first rotating member 6, one end of the first torsion spring 5 abuts against the side wall of the shell 1, and the other end of the first torsion spring 5 abuts against the upper connecting rod 2, so that the upper connecting rod 2 can abut against the shell 1 through the first torsion spring 5.

[0068] Preferably, the first torsion spring 5 is in a slightly compressed state after installation, so that the elastic force of the first torsion spring 5 can be used to apply a pressure to the upper connecting rod 2 so that its first limiting surface 21 can abut against the outer wall of the shell 1 for rotation limiting of the upper connecting rod 2.

[0069] As a second preferred embodiment, the first elastic member may also be configured as a coil spring, which is fixed to the housing 1, and the free end of which is connected to the upper connecting rod 2. The coil spring is stretched or released by the rotation of the upper connecting rod 2, so that the elastic force of the coil spring acts on the upper connecting rod 2, thereby realizing the rotation limiting function of the upper connecting rod 2. As a third preferred embodiment, the first elastic member may also be configured as a compression spring, and the two ends of the compression spring are respectively connected to the upper connecting rod 2 and the housing 1. The compression spring is compressed or released by the rotation of the upper connecting rod 2, so that the elastic force of the compression spring acts on the upper connecting rod 2, thereby realizing the rotation limiting function of the upper connecting rod 2.

[0070] Please see attached Figure 1 and attached Figure 2 A second elastic member is provided between the upper connecting rod 2 and the synchronization rod 3. When the object 9 is inserted into the cavity, the synchronization rod 3 and the upper connecting rod 2 rotate synchronously through the second elastic member.

[0071] As a first preferred embodiment, the second elastic member is configured as a second torsion spring 7 sleeved on the second rotating member 8, and two ends of the second torsion spring 7 abut against the upper connecting rod 2 and the synchronization rod 3 respectively.

[0072] The installation direction of the second torsion spring 7 is installed according to the rotation direction of the synchronization rod 3 relative to the upper connecting rod 2, so that when the synchronization rod 3 is stationary relative to the upper connecting rod 2, that is, when the third limiting surface 31 abuts against the second limiting surface 22, the second torsion spring 7 is not subjected to force; and when the synchronization rod 3 rotates clockwise relative to the upper connecting rod 2, the second torsion spring 7 is squeezed, so that the second torsion spring 7 accumulates force, which is convenient for the subsequent rotation and reset of the synchronization rod 3.

[0073] The extrusion deformation of the second torsion spring 7 is used to relieve the force of the first torsion spring 5. The upper connecting rod 2 can rotate clockwise to reset during the unloading process of the first torsion spring 5, so that the first limiting surface 21 is attached to the outer wall of the shell 1, and the synchronization rod 3 can rotate clockwise relative to the upper connecting rod 2.

[0074] As a second preferred embodiment, the second elastic member can also be set as a compression spring, the two ends of which are connected to the upper connecting rod 2 and the synchronization rod 3. The synchronization rod 3 rotates relative to the upper connecting rod 2 to compress the compression spring, so that the compression spring accumulates force, which facilitates the subsequent rotation and reset of the synchronization rod 3.

[0075] Please see attached Figure 7 To Attachment Fig. 9 The synchronization rod 3 is pivotally connected to the lower connecting rod 4 . After the object 9 is inserted into the cavity, the pivot center of the synchronization rod 3 and the lower connecting rod 4 is not higher than the axis of the second rotating member 8 .

[0076] As a preferred embodiment, the synchronization rod 3 is formed with a fourth rotating portion 302, and one end of the lower connecting rod 4 is formed with a third rotating member 41, and the third rotating member 41 is rotatably connected to the fourth rotating portion 302, so that the synchronization rod 3 is rotatably connected to one end of the lower connecting rod 4. The third rotating member 41 can be a short shaft and protrudingly arranged on both sides of one end of the lower connecting rod 4, and the fourth rotating portion 302 can be a pair of ear plates with holes matching the short shaft, so as to facilitate the relative rotation between the lower connecting rod 4 and the synchronization rod 3, and realize the pivot connection between the synchronization rod 3 and the lower connecting rod 4.

[0077] The elastic force of the first torsion spring 5 applies a certain pressure to the upper connecting rod 2. When the pressure is transmitted to the object 9 through the upper connecting rod 2, the synchronization rod 3 and the lower connecting rod 4 in sequence, it passes through the second rotating member 8 and the third rotating member 41. The axial center height of the third rotating member 41, that is, the pivot center of the synchronization rod 3 and the lower connecting rod 4, is lower than or equal to the axial center height of the second rotating member 8, so as to ensure that a slightly downward pressure is applied to the object 9, thereby ensuring the stable placement of the object 9 in the shell 1, and avoiding the problem of reverse self-locking when the object 9 is taken out.

[0078] Please see attached Figure 1 , Attachment Figure 2 and attached Figure 7 The other end of the lower connecting rod 4 forms a limiting portion 42, and a limiting slide groove 12 is formed on the outer wall of the shell 1. The limiting portion 42 can be slidably embedded in the limiting slide groove 12, so that the other end of the lower connecting rod 4 is movably connected to the shell 1.

[0079] Preferably, the limiting grooves 12 and the limiting portions 42 are symmetrically arranged in pairs, and a pair of limiting grooves 12 cooperate with a pair of limiting portions 42 to provide guidance and limitation for the movement of the lower connecting rod 4, ensuring that the lower connecting rod 4 moves in conjunction with the synchronization rod 3 through up and down movement and rotation during the insertion and removal of the object 9.

[0080] Please see attached Figure 8 and attached Fig. 9 The portion between the eaves 33 of the synchronization rod 3 and the fourth rotating portion 302 is a curved surface structure, and when the object 9 is inserted, it slides in contact with the object 9 to form a first guiding curved surface; see the attached Figure 7 The lower connecting rod 4 is an arc surface structure, and when the object 9 is taken out, it slides in contact with the object 9 to form a second guiding arc surface.

[0081] The arc surface structure of the synchronization rod 3 provides a first guiding arc surface for the insertion of the object 9, and the arc surface structure of the lower connecting rod 4 provides a second guiding arc surface for the removal of the object 9. The insertion and removal of the inverted object 9 will not be affected by the presence of raised structures 901 such as the protective shell steps and the camera, and the arc surface structure will not cause wear to the object 9.

[0082] Please see attached Figure 4 and attached Figure 5 , the installation method of the utility model is:

[0083] Taking the wireless charging of a mobile phone as an example, the wireless charging module 101 is fixed to the outer wall of the housing 1 away from the opening 11 by screws, and other functional modules can be expanded to the wireless charging module 101 according to actual use requirements. The housing 1 can be installed on the vehicle body by bolts according to actual use requirements, for example, the housing 1 can be installed on the side panel of the car seat 10, the rear seat armrest, the vehicle console, the door panel storage compartment, etc., which is convenient for the use of the mobile phone, that is, the item 9, and the application scenario is flexible and unlimited.

[0084] Please see attached Figure 1 To Attachment Fig.14 Taking the insertion and removal of a mobile phone as an example, the use method and working principle of the utility model are as follows:

[0085] Please see attached Fig.10 and attached Fig.11 , Insertion phase:

[0086] When the mobile phone is inserted downward into the cavity of the housing 1 , the end of the mobile phone presses downward against the synchronization rod 3 , and the first guiding arc surface of the synchronization rod 3 can ensure that the mobile phone is smoothly inserted downward.

[0087] During the insertion process, the third limiting surface 31 of the synchronization rod 3 abuts against the second limiting surface 22 of the upper connecting rod 2, and the synchronization rod 3 and the upper connecting rod 2 are kept relatively still by plane contact and the upper connecting rod 2 is pushed to rotate synchronously, so that the upper connecting rod 2 rotates counterclockwise around the first rotating member 6. At this time, the first elastic member is squeezed and force is accumulated, and the first limiting surface 21 is separated from the outer wall of the housing 1.

[0088] When the synchronization rod 3 rotates synchronously with the upper connecting rod 2, the rotation of the synchronization rod 3 drives the lower connecting rod 4 to move. The linkage process of the lower connecting rod 4 is: the lower connecting rod 4 rotates relative to the synchronization rod 3 through the third rotating member 41. Since the limiting portion 42 is restricted by the limiting slide groove 12, it can only make up and down linear motion along the limiting slide groove 12, so that the lower connecting rod 4 rotates and slides downward along the limiting slide groove 12.

[0089] The motion trajectory of the synchronization rod 3 is a circular motion around the first rotating member 6. The lower connecting rod 4 moves downward under the guidance of the limiting slide groove 12 and rotates relative to the synchronization rod 3, so that the mobile phone can be inserted into the cavity of the housing 1. After the mobile phone is inserted into the cavity, the elastic force formed by the compression of the first elastic member is transmitted to the mobile phone through the upper connecting rod 2, the synchronization rod 3 and the lower connecting rod 4 in sequence, so that the mobile phone is pressed tightly against the inner wall of the housing 1 through the lower connecting rod 4, ensuring the stability of the mobile phone without shaking, and making the mobile phone close to the wireless charging module 101, ensuring the effectiveness and charging efficiency of wireless charging.

[0090] Please see attached Fig.12 To Attachment Fig.14 , removal stage:

[0091] If the raised structure 901 of the mobile phone camera is located at the upper part, as shown in the attached Fig.10 As shown, when the mobile phone is pulled out of the housing 1, since the mobile phone and the lower connecting rod 4 are in abutment state, the friction force is used to form an upward force on the lower connecting rod 4 when the mobile phone is taken out, so that under the action of this force, the limiting portion 42 moves upward along the limiting slide groove 12, and the fourth rotating portion 302 of the synchronization rod 3 is driven by the third rotating member 41 to move upward and rotate relative to the lower connecting rod 4.

[0092] If the raised structure 901 such as the camera of the mobile phone is located at the bottom, as shown in the attached Fig.12 As shown, when the mobile phone is pulled out of the shell 1, the raised structure 901 of the mobile phone's camera etc. pushes the lower connecting rod 4 upward, thereby forming an upward force on the lower connecting rod 4, so that the limiting portion 42 moves upward along the limiting slide groove 12 under the action of this force, and the fourth rotating portion 302 of the synchronization rod 3 is driven to move upward and rotate relative to the lower connecting rod 4 through the third rotating member 41.

[0093] When the fourth rotating part 302 moves upward and rotates, the synchronization rod 3 rotates clockwise around the second rotating member 8. At this time, the third limiting surface 31 is separated from the second limiting surface 22, and the rotating surface 32 slides and fits onto the second limiting surface 22 as the synchronization rod 3 rotates. The rotating surface 32 with the arc surface structure ensures the stable rotation of the synchronization rod 3 relative to the upper connecting rod 2 and squeezes the second elastic member.

[0094] Since the upper connecting rod 2 is pressed against the shell 1 through the first limiting surface 21, the first elastic member is relieved of force, the third limiting surface 31 is separated from the second limiting surface 22, and the synchronization rod 3 rotates relative to the upper connecting rod 2 through the rotational contact between the rotating surface 32 and the second limiting surface 31. During the rotation of the synchronization rod 3 relative to the upper connecting rod 2, the second elastic member is compressed to provide a force on the object. Since the force provided by the second elastic member is smaller than the clamping force provided by the first elastic member, the object and its protruding structure can pass through the three-link structure smoothly.

[0095] After the mobile phone is taken out, the pressure on the synchronization rod 3 is released, the second elastic member unloads the force, and the elastic force of the second elastic member is used to make the synchronization rod 3 rotate counterclockwise around the second rotating member 8 to reset, and the third limiting surface 31 is re-connected to the second limiting surface 22 of the upper connecting rod 2, and the lower connecting rod 41 is reset in conjunction with the synchronization rod 3 through the third rotating member 41 and the limiting portion 42.
