[0015] Another technical solution to the technical problem solved by the present invention is to provide an electronic equipment bracket for placing electronic equipment, wherein the electronic equipment bracket comprises the above-mentioned clamping device.

[0016] Compared with the prior art, the clamping device and electronic equipment bracket provided by the present invention have the following advantages:

[0017] 1. An embodiment of the present invention provides a clamping device, which includes a clamping module, a bracket module and a locking module connected in sequence, and the locking module is used to lock the clamping module after the bracket module is connected. By arranging a ratchet structure on the circumferential outer surface of the nut, the rotation of the nut can be limited by the transmission structure after the nut is tightened. The transmission structure can only drive the ratchet to rotate in a specific direction, so that the nut can only rotate in a specific direction. Through this design, it can be prevented that outsiders can easily unscrew the nut, and then steal or destroy related equipment, thereby avoiding property losses.

[0018] 2. In the clamping device provided in the embodiment of the present invention, through the meshing state between the ratchet and the first limit member or the second limit member, the ratchet is driven by the first limit member or the second limit member when the shell structure is rotated, so that the nut rotates in a clockwise or counterclockwise direction to achieve the locking or disassembly of the nut. The ratchet structure ensures that the nut has a good anti-theft function.

[0019] 3. In the clamping device provided in the embodiment of the present invention, the meshing between the supporting member and the ratchet is achieved through the cooperation between the supporting member, the elastic member and the rotating shaft. One end of the rotating shaft on the limiting member serves as a rotating section, driving the supporting member to rotate relative to the rotating shaft. One end of the supporting member serves as a working section. The elastic member is located on the side away from the locking assembly, which can ensure that the ratchet can only rotate in a specific direction under different locking modes, and ensure that after the nut is rotated in one direction to achieve locking, it cannot be rotated in another direction to achieve disassembly, thereby improving the user experience of the clamping device.

[0020] 4. In the clamping device provided in the embodiment of the present invention, when the shell structure rotates in a specific direction, since the rotating shaft is fixedly arranged inside the shell structure, the abutting surface of the abutting member away from the rotating shaft can abut the ratchet, thereby driving the nut to rotate; since the elastic member is movably deformable, the abutting surface of the abutting member away from the elastic member cannot drive the nut to rotate, which will cause the shell structure to rotate idly relative to the nut.

[0021] 5. In the clamping device provided in the embodiment of the present invention, the locking assembly can be rotated to control the engagement of the abutment member and the ratchet. At this time, the ratchet is in contact with the abutment surface on the abutment member. When the nut can be rotated in a specific direction, the abutment surface on the abutment member away from the end of the rotating shaft is pushed by the rotating shaft to contact the ratchet, thereby driving the ratchet to rotate. The nut can be rotated in opposite directions through the two abutment members.

[0022] 6. In the clamping device provided by the embodiment of the present invention, when the locking assembly rotates, the first rotating member drives the second rotating member to rotate, and the second rotating member abuts against the abutting member on one side, so that the abutting member on the other side engages with the ratchet; by providing a boss on the side of the first rotating member and providing a through groove on the shell structure to expose the boss, the boss slides in the through groove to abut against the inner side wall of the through groove, thereby realizing the limited fit between the locking assembly and the shell structure. In addition, the first rotating member and the boss are exposed after being inserted into the through groove, so that the user can know the locking mode currently in which the locking module in the clamping device is.

[0023] 7. In the clamping device provided in the embodiment of the present invention, the inner surface of the locking groove needs to cooperate with a specific external locking device, and the first rotating member is driven by the external locking device to change the locking mode of the nut. Through this design, it can be prevented that outsiders drive the holding member to rotate by using tools collected at hand, thereby achieving a good anti-theft effect.

[0024] 8. In the clamping device provided in the embodiment of the present invention, by limiting the movement of the ratchet and the nut in the horizontal and vertical directions, the overall structural stability of the ratchet and the nut can be ensured, and the stability of the fixed connection between the ratchet and the nut and the shell structure can be ensured, so that the limit member can smoothly engage with the ratchet and drive the ratchet and the nut to rotate together when the shell rotates in a specific direction.

[0025] 9. In the clamping device provided in the embodiment of the present invention, the first connecting member and the second connecting member are respectively a ball head bracket and a screw thread bracket, and the ball head bracket can be engaged with the screw thread bracket; since the circumferential outer surface of the second connecting member is provided with an external thread, and the circumferential inner surface of the nut is provided with an internal thread, that is, the nut and the second connecting member are threadedly connected, when the ratchet structure rotates, the nut can lock or disassemble the second connecting member, thereby realizing the locking and fixing of the first connecting member, so that the first connecting member cannot be separated from the second connecting member, thereby extending the service life of the clamping device and improving the user experience.

[0026] 10. An embodiment of the present invention further provides an electronic device bracket for placing electronic devices, and the electronic device bracket includes the above-mentioned clamping device.

[0027] It should be noted that the electronic equipment bracket of the embodiment of the present invention has the same beneficial effects as the above-mentioned clamping device, which will not be described in detail here.

[0049] See also Figure 1 , Figure 2 and Figure 3 The embodiment of the present invention provides a clamping device 100, which includes a clamping module 20, a bracket module 30 and a locking module 10 connected in sequence; the clamping module 20 is provided with a first connecting member 201, the bracket module 30 is provided with a second connecting member 301 connected to the first connecting member 201, and the locking module 10 includes a shell structure 1, a nut 2 and a transmission structure 3, the shell structure 1 is provided with a hollow channel 11 for fixing the nut 2, and the shell structure 1 and the transmission structure 3 cooperate to drive the nut 2 to rotate, so as to lock the first connecting member 201 and the second connecting member 301;

[0050] The housing structure 1 has an accommodating chamber inside, and the transmission structure 3 includes a ratchet 31, a locking assembly 32, a first limiting assembly 33 and a second limiting assembly 34 arranged in the accommodating chamber, the ratchet 31 is arranged on the circumferential outer surface of the nut 2, and the locking assembly 32 is located between the first limiting assembly 33 and the second limiting assembly 34;

[0051] The nut 2 is rotatably matched with the housing structure 1, and the locking assembly 32 drives the first limiting assembly 33 or the second limiting assembly 34 to elastically resist the ratchet 31;

[0052] When the first limiting assembly 33 abuts against the ratchet 31, the housing structure 1 drives the nut 2 to rotate in the first direction and idles relative to the nut 2 in the second direction; when the second limiting assembly 34 abuts against the ratchet 31, the housing structure 1 drives the nut 2 to rotate in the second direction and idles relative to the nut 2 in the first direction;

[0053] One of the first direction and the second direction is clockwise, and the other is counterclockwise.

[0054] As a clamp for assisting in fixing electronic devices, the clamping device 100 includes a clamping module 20, a bracket module 30 and a locking module 10 which are connected in sequence; the clamping module 20 can be fixed on a vehicle, or can be fixedly clamped on the edge of a desktop, the top of a TV, etc. The bracket module 30 is mainly used to be connected to different external bracket components, and these external bracket components are used to fix electronic devices such as microphones, cameras, mobile phones or tablets. The locking module 10 is used to lock the clamping module 20 after it is connected to the bracket module 30.

[0055] Specifically, in the embodiment of the present invention, the first connecting member 201 on the clamping module 20 can be detachably connected to the second connecting member 301 on the bracket module 30, and the nut 2 is rotated to lock the first connecting member 201 and the second connecting member 301.

[0056] For the locking module 10 in the clamping device 100, a ratchet structure is provided on the circumferential outer surface of the nut 2, and the ratchet 31 is integrally formed with the nut 2. The rotation of the nut 2 can be limited by the transmission structure 3 after the nut 2 is tightened. The transmission structure 3 can only drive the ratchet 31 to rotate in a specific direction, so that the nut 2 can only rotate in a specific direction. Through this design, the technical problem that the existing clamping device does not have an anti-theft function is solved, which prevents outsiders from easily unscrewing the nut and then stealing or destroying related equipment to cause property loss.

[0057] Specifically, the locking module 10 takes the nut 2 as the main body, and the transmission structure 3 realizes the detachable connection between the nut 2 and the second connecting member 301, wherein the detachable connection is a threaded connection, and the nut 2 can be fixedly placed on the shell structure 1, and the ratchet 31, the locking assembly 32, the first limit assembly 33 and the second limit assembly 34 of the transmission structure 3 are placed in the accommodating cavity inside the shell structure 1. By setting the shell structure 1, the various components of the transmission structure 3 can be protected.

[0058] In particular, the adjustment end of the locking component 32 is relatively arranged inside the outer surface of the shell structure 1, and cannot be adjusted by ordinary unlocking tools (such as wrenches, screwdrivers, etc.), and requires the use of a specific polygonal wrench to adjust it. This design can prevent others from arbitrarily adjusting the locking component 32, thereby improving the anti-theft performance of the locking device 10.

[0059] It can be understood that the internal thread of the nut 2 is located in the hollow channel 11, the two ends of the nut 2 are fixed by the shell structure 1, the ratchet 31 is arranged on the circumferential outer surface of the nut 2, and the locking component 32 drives the first limiting component 33 or the second limiting component 34 to elastically abut the ratchet 31. Since the first limiting component 33 and the second limiting component 34 are respectively located on both sides of the locking component 32, when the locking component 32 drives the first limiting component 33 to elastically abut the ratchet 31, the locking component 32 abuts the second limiting component 34; when the locking component 32 drives the second limiting component 34 to elastically abut the ratchet 31, the locking component 32 abuts the first limiting component 33.

[0060] It should be noted that the nut 2 is rotationally coordinated with the shell structure 1. When the first limit component 33 or the second limit component 34 elastically resists the ratchet 31, a clockwise or counterclockwise force is applied to rotate the shell structure 1 to drive the nut 2 to rotate; it can be understood that since the resistance to the ratchet 31 is achieved by applying an elastic force by the first limit component 33 or the second limit component 34, when the rotation direction of the shell structure 1 corresponds to the direction of applying the elastic force, the first limit component 33 or the second limit component 34 will compress the elastic structure, so that the first limit component 33 or the second limit component 34 cannot drive the ratchet 31 to rotate, and thus the nut 2 cannot be rotated.

[0061] Furthermore, when the first limiting component 33 abuts against the ratchet 31, the shell structure 1 can only drive the nut 2 to rotate from the first direction, and when the shell structure 1 rotates along the second direction, the shell structure 1 idles relative to the nut 2; when the second limiting component 34 abuts against the ratchet 31, the shell structure 1 can only drive the nut 2 to rotate from the second direction, and when the shell structure 1 rotates along the first direction, the shell structure 1 idles relative to the nut 2; the first direction and the second direction are one clockwise and the other counterclockwise.

[0062] In the embodiment of the present invention, the first direction is clockwise, and the second direction is counterclockwise. When the first limiting assembly 33 abuts against the ratchet 31, the housing structure 1 can only drive the nut 2 to rotate in the clockwise direction, and when the housing structure 1 rotates in the counterclockwise direction, the housing structure 1 will idle relative to the nut 2; in contrast to when the first limiting assembly 33 abuts against the ratchet 31, when the second limiting assembly 34 abuts against the ratchet 31, the housing structure 1 can only drive the nut 2 to rotate in the counterclockwise direction, and when the housing structure 1 rotates in the clockwise direction, the housing structure 1 will idle relative to the nut 2.

[0063] In some embodiments, the first limiting component 33 includes a first limiting member 331 and a first elastic member 332, and the second limiting component 34 includes a second limiting member 341 and a second elastic member 342; the first limiting member 331 can rotate relative to the shell structure 1, one end of the first elastic member 332 abuts against the inner wall of the shell structure 1, and the other end contacts the first limiting member 331; the second limiting member 341 can rotate relative to the shell structure 1, one end of the second elastic member 342 abuts against the inner wall of the shell structure 1, and the other end contacts the second limiting member 341.

[0064] In the embodiment of the present invention, the locking assembly 32 can rotate relative to the housing structure 1 to abut against the first limiting member 331 or the second limiting member 341 , and respectively make the second limiting member 341 or the first limiting member 331 engage with the ratchet 31 .

[0065] In the clamping device 100 provided by the present invention, the locking module 10 is in meshing state between the ratchet 31 and the first limit member 331 or the second limit member 341. When the shell structure 1 is rotated, the ratchet 31 is driven by the first limit member 331 or the second limit member 341 to make the nut 2 rotate in a clockwise or counterclockwise direction, thereby realizing the locking or disassembly of the nut 2. The ratchet structure ensures that the nut 2 has a good anti-theft function.

[0066] It can be understood that when the first limit member 331 is engaged with the ratchet 31, the locking assembly 32 is rotated to abut against the second limit member 341. At this time, the shell structure 1 can only drive the nut 2 to rotate in the clockwise direction. When the shell structure 1 rotates in the counterclockwise direction, the shell structure 1 idles relative to the nut 2; when the second limit member 341 is engaged with the ratchet 31, it is just the opposite. Through this design, when the shell structure 1 can drive the nut 2 in the clockwise direction, the internal thread of the nut 2 and the external thread of the external structure rotate relative to each other to achieve the locking of the nut 2. When the shell structure 1 drives the nut 2 in the counterclockwise direction, the separation and disassembly between the nut 2 and the external structure is achieved.

[0067] It should be noted that the locking assembly 32 drives the first limiting member 331 or the second limiting member 341 to elastically resist the ratchet 31 through the elastic deformation of the first elastic member 332 or the second elastic member 342 . When the locking assembly 32 rotates to abut against the first limit member 331, the first limit member 331 will apply a thrust to the first elastic member 332 to compress the first elastic member 332. At this time, one end of the second limit member 341 is not abutted by the locking assembly 32, and the second elastic member 342 restores its elastic deformation to elastically abut the second limit member 341, so that the second limit member 341 engages with the ratchet 31; when the locking assembly 32 rotates to abut against the second limit member 341, the second limit member 341 will apply a thrust to the second elastic member 342 to compress the second elastic member 342. At this time, one end of the first limit member 331 is not abutted by the locking assembly 32, and the first elastic member 332 restores its elastic deformation to elastically abut the first limit member 331, so that the first limit member 331 engages with the ratchet 31.

[0068] See also Figure 3 and Figure 4 The first limiting member 331 includes a first rotating shaft 3311 and a first resisting member 3312 which are connected to each other. The first resisting member 3312 can rotate relative to the first rotating shaft 3311 , and a side of the first resisting member 3312 away from the locking assembly 32 contacts the first elastic member 332 .

[0069] It can be understood that the locking module 10 realizes the engagement between the supporting member and the ratchet 31 through the cooperation between the supporting member, the elastic member and the rotating shaft, wherein the first rotating shaft 3311 itself is rotatable, and in the process of rotating the locking assembly 32 to resist the first limit member 331, the first supporting member 3312 realizes rotation with the first rotating shaft 3311 as the rotating axis.

[0070] Similarly, the second limiting member 341 includes a connected second rotating shaft 3411 and a second supporting member 3412. The second supporting member 3412 can rotate relative to the second rotating shaft 3411, and the side of the second supporting member 3412 away from the locking assembly 32 is in contact with the second elastic member 342; wherein the second rotating shaft 3411 itself can rotate, and in the process of rotating the locking assembly 32 to support the second limiting member 341, the second supporting member 3412 rotates with the second rotating shaft 3411 as the rotation axis.

[0071] In some embodiments, one end of the first limiting member 331 close to the first rotating shaft 3311 serves as a rotating section, which can drive the first supporting member 3312 to rotate relative to the first rotating shaft 3311, and the end close to the first supporting member 3312 serves as a working section, and the first elastic member 332 is located on a side away from the locking assembly 32; one end of the second limiting member 341 close to the second rotating shaft 3411 serves as a rotating section, which can drive the second supporting member 3412 to rotate relative to the second rotating shaft 3411, and the end close to the second supporting member 3412 serves as a working section, and the second elastic member 342 is located on a side away from the locking assembly 32.

[0072] It should be noted that, by providing a relatively rotatable rotating shaft and a supporting member, as well as the matching relationship between the rotating shaft, the supporting member and the elastic member, it can be ensured that the ratchet 31 can only rotate in a specific direction under different locking modes, that is, the nut 2 is driven to rotate to achieve one of the locking or disassembly actions, ensuring that after the nut 2 is rotated in one direction to achieve locking, it cannot be simply disassembled by rotating in another direction.

[0073] See also Figure 3 and Figure 5 The first supporting member 3312 is provided with a first supporting surface 3313 and a second supporting surface 3314, the first supporting surface 3313 is located on a side of the first supporting member 3312 away from the first rotating shaft 3311, and the second supporting surface 3314 is located on a side of the first supporting member 3312 away from the first elastic member 332; the second supporting member 3412 is provided with a third supporting surface 3413 and a fourth supporting surface 3414, the third supporting surface 3413 is located on a side of the second supporting member 3412 away from the second rotating shaft 3411, and the fourth supporting surface 3414 is located on a side of the second supporting member 3412 away from the second elastic member 342.

[0074] In the embodiment of the present invention, when the shell structure 1 rotates in a specific direction, since the rotating shaft is fixedly arranged inside the shell structure 1, the abutting surface of the abutting member away from the rotating shaft can abut the ratchet 31, thereby driving the nut 2 to rotate.

[0075] It can be understood that the side of the first supporting member 3312 away from the first rotating shaft 3311 is the first supporting surface 3313, and the side of the first supporting member 3312 away from the first elastic member 332 is the second supporting surface 3314; when the locking assembly 32 drives the first supporting member 3312 to elastically resist the ratchet 31, the shell structure 1 is rotated in the clockwise direction, and the first rotating shaft 3311 can drive the first supporting member 3312 to rotate the ratchet 31, thereby driving the rotation of the nut 2 to achieve the locking of the nut 2.

[0076] The side of the second supporting member 3412 away from the second rotating shaft 3411 is the third supporting surface 3413, and the side of the second supporting member 3412 away from the second elastic member 342 is the fourth supporting surface 3414; when the locking assembly 32 drives the second supporting member 3412 to elastically resist the ratchet 31, the shell structure 1 is rotated counterclockwise, and the second rotating shaft 3411 can drive the second supporting member 3412 to rotate the ratchet 31, thereby driving the rotation of the nut 2 to achieve the removal of the nut 2.

[0077] It should be noted that, since the first elastic member 332 and the second elastic member 342 are movable and deformable, the second abutting surface 3314 on the first abutting member 3312 that is away from the first elastic member 332 and the fourth abutting surface 3414 on the second abutting member 3412 that is away from the second elastic member 342 cannot drive the nut 2 to rotate. In other words, when the first abutting member 3312 abuts against the ratchet 31, rotating the housing structure 1 in the counterclockwise direction will cause the housing structure 1 to rotate idly relative to the nut 2; when the second abutting member 3412 abuts against the ratchet 31, rotating the housing structure 1 in the clockwise direction will cause the housing structure 1 to rotate idly relative to the nut 2; it can be seen that the ratchet structure can realize the switching back and forth of the nut 2 between the two working modes of the disassembly mode and the anti-theft mode.

[0078] Please continue reading Figure 3 and Figure 4 The locking assembly 32 can rotate relative to the housing structure 1 to abut against the first abutting member 3312 or the second abutting member 3412 , and respectively make the second abutting member 3412 or the first abutting member 3312 engage with the ratchet 31 .

[0079] In the embodiment of the present invention, the locking component 32 is rotated to control the engagement of the abutment and the ratchet 31. At this time, the ratchet 31 contacts the abutment surface on the abutment. When the nut 2 can be rotated in a specific direction, the abutment surface on the abutment away from the end of the rotating shaft is pushed by the rotating shaft to contact the ratchet 31, thereby driving the ratchet 31 to rotate. The nut 2 can be rotated in opposite directions through the two abutments.

[0080] Furthermore, when the first abutting member 3312 is engaged with the ratchet 31, the ratchet 31 contacts the first abutting surface 3313 and the second abutting surface 3314 respectively; when the second abutting member 3412 is engaged with the ratchet 31, the ratchet 31 contacts the third abutting surface 3413 and the fourth abutting surface 3414 respectively.

[0081] It can be understood that the first supporting surface 3313 and the second supporting surface 3314 on the first supporting member 3312 are adjacent to each other, and the third supporting surface 3413 and the fourth supporting surface 3414 on the second supporting member 3412 are adjacent to each other.

[0082] When the first supporting member 3312 is engaged with the ratchet 31, rotating the shell structure 1 in the clockwise direction can make the first supporting surface 3313 of the first supporting member 3312 drive the ratchet 31 to rotate, and when the shell structure 1 is rotated in the counterclockwise direction, the first elastic member 332 will cause the first supporting member 3312 to make a circumferential reciprocating motion relative to the ratchet 31, that is, it cannot drive the ratchet 31 to rotate, and at this time the shell structure 1 rotates idly relative to the ratchet 31; when the second supporting member 3412 is engaged with the ratchet 31, rotating the shell structure 1 in the counterclockwise direction can make the third supporting surface 3413 of the second supporting member 3412 drive the ratchet 31 to rotate, and when the shell structure 1 is rotated in the clockwise direction, the second elastic member 342 will cause the second supporting member 3412 to make a circumferential reciprocating motion relative to the ratchet 31, that is, it cannot drive the ratchet 31 to rotate, and at this time the shell structure 1 rotates idly relative to the ratchet 31.

[0083] See also Figure 3 , Figure 4 and Figure 7 The locking assembly 32 includes a first rotating member 321 and a second rotating member 322 connected to each other. The first rotating member 321 can drive the second rotating member 322 to rotate relative to the shell structure 1, so that the second rotating member 322 abuts against the first abutting member 3312 or the second abutting member 3412.

[0084] The shell structure 1 is provided with a through slot 12 , and a boss 323 is provided on the side of the first rotating member 321 . The first rotating member 321 and the boss 323 are exposed after being penetrated through the through slot 12 . The boss 323 can slide in the through slot 12 to abut against the inner wall of the through slot 12 .

[0085] In the embodiment of the present invention, when the locking assembly 32 rotates, the first rotating member 321 drives the second rotating member 322 to realize the linkage between the second rotating member 322 and the first rotating member 321, and the second rotating member 322 abuts against the abutting member on one side, so that the abutting member on the other side engages with the ratchet 31.

[0086] Specifically, the rotation angle of the first rotating member 321 can be adjusted by the portion of the first rotating member 321 exposed from the through slot 12, so as to drive the second rotating member 322 to elastically abut against the first abutting member 3312 or the second abutting member 3412. When the first rotating member 321 and the first elastic member 332 abut against the first abutting member 3312, the second abutting member 3412 meshes with the ratchet 31; when the second rotating member 322 and the second elastic member 342 elastically abut against the first abutting member 3312, the first abutting member 3312 meshes with the ratchet 31.

[0087] It can be understood that by providing the boss 323 on the side of the first rotating member 321 and providing the through slot 12 on the housing structure 1 to expose the boss 323, the boss 323 can slide in the through slot 12 to abut against the inner wall of the through slot 12, thereby realizing the limited fit between the locking assembly 32 and the housing structure 1. In addition, by providing the through slot 12 to expose the first rotating member 321 and the boss 323 after being penetrated, the user can know the current locking mode of the locking module 10, thereby improving the user's use experience.

[0088] Furthermore, a locking groove 3211 is provided at one end of the first rotating member 321 that is exposed after passing through the slot 12 , and the inner surface of the locking groove 3211 cooperates with an external locking device.

[0089] In an embodiment of the present invention, the inner surface of the locking groove 3211 needs to cooperate with a specific external locking device, and the first rotating member 321 is driven by the external locking device to change the working mode of the nut 2. Through this design, it can be prevented that outsiders use tools collected at hand to drive the supporting member to rotate, thereby achieving a good anti-theft effect.

[0090] It can be understood that the locking groove 3211 set at the end of the first rotating member 321 is a polygonal groove, which requires a specific tool that matches the shape of the locking groove 3211 to cooperate with the locking groove 3211 to control the rotation of the first rotating member 321, thereby switching the working mode of the locking module 10.

[0091] As an optional embodiment, the locking groove 3211 is a hexagonal groove, and the external locking device is an hexagonal wrench, which is inserted into the inner surface of the locking groove 3211 to rotate the first rotating member 321; that is, the locking module 10 in the embodiment of the present invention needs to be operated by an hexagonal wrench of corresponding size model to operate the first rotating member 321, so that the first rotating member 321 rotates a corresponding angle to put the locking module 10 in disassembly mode or anti-theft mode.

[0092] It can be understood that the type and size of the locking groove 3211 and the external locking device can be adjusted according to actual needs. The above description is only one embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the principles of the present invention should be included in the scope of protection of the present invention.

[0093] The above design can prevent outsiders from driving the first rotating member 321 to rotate and switch the locking module 10 to the disassembly mode or anti-theft mode without using unlocking tools or only using tools collected at hand, thereby ensuring a good anti-theft effect.

[0094] See also Figure 1 , Figure 3 and Figure 6 The shell structure 1 includes a coverable shell 13 and a bottom plate 14. The circumferential outer surface of the nut 2 abuts against the inner wall of the shell 13 on the hollow channel 11, and the top surface of the ratchet 31 abuts against the inner wall of the shell 13 away from the bottom plate 14 to close the accommodating cavity.

[0095] In the clamping device 100 provided in the embodiment of the present invention, the locking module 10 can ensure the overall structural stability of the ratchet 31 and the nut 2 by limiting the movement of the ratchet 31 and the nut 2 in the vertical and horizontal directions, and ensure the stability of the fixed connection between the ratchet 31 and the nut 2 and the shell structure 1, so that the limit member can smoothly engage with the ratchet 31, and drive the ratchet 31 and the nut 2 to rotate together when the shell 13 rotates in a specific direction.

[0096] It can be understood that the ratchet structure is arranged in the accommodating chamber, and the closure of the accommodating chamber is achieved by the ratchet 31 abutting against the inner wall surface of the shell 13, the nut 2 being fixedly placed on the bottom plate 14, and the nut 2 abutting against the inner wall of the shell 13.

[0097] Specifically, when the shell 13 is covered on the base plate 14, the nut 2 is fixedly placed on the base plate 14, and the inner wall surface of the shell 13 and the inner bottom wall of the base plate 14 abut against the upper and lower ends of the ratchet 31, thereby preventing the nut 2 from moving in the vertical direction; the circumferential outer surface of the nut 2 can abut against the inner side wall of the shell 13. Since the ratchet 31 is arranged on the circumferential outer surface of the nut 2, that is, the nut 2 is located on the inner ring of the ratchet 31, the abutment against the inner side wall of the shell 13 can prevent the nut 2 from moving in the horizontal direction, thereby ensuring that the clamping device 100 can be used normally and has an anti-theft effect.

[0098] See also Figure 1 The first connecting member 201 is a ball head bracket, and the second connecting member 301 is a screw thread bracket; the circumferential outer surface of the second connecting member 301 is provided with an external thread 3010, and the circumferential inner surface of the nut 2 is provided with an internal thread 21, and the nut 2 can be rotated relative to the second connecting member 301 to lock the first connecting member 201.

[0099] In the clamping device 100 provided in the embodiment of the present invention, the first connecting member 201 and the second connecting member 301 are respectively a ball head bracket and a screw thread bracket, and the ball head bracket can be engaged with the screw thread bracket.

[0100] It should be noted that since the circumferential outer surface of the second connecting member 301 is provided with an external thread 3010 and the circumferential inner surface of the nut 2 is provided with an internal thread 21, that is, the nut 2 and the second connecting member 301 are threadedly connected, when the ratchet structure rotates, the nut 2 can lock or disassemble the second connecting member 301, thereby realizing the locking and fixing of the first connecting member 201, so that the first connecting member 201 cannot be separated from the second connecting member 301, thereby extending the service life of the clamping device 100 and improving the user experience.

[0101] See also Figure 1 and Figure 8 The embodiment of the present invention further provides an electronic device bracket 101 for placing electronic devices. The electronic device bracket 101 includes the above-mentioned clamping device 100.

[0102] It can be understood that the electronic device bracket 101 of the embodiment of the present invention has the same beneficial effects as the clamping device 100 of the above embodiment, and the electronic devices include but are not limited to microphones, cameras, mobile phones, and tablet computers.

[0103] In some embodiments, the electronic device bracket 101 generally further includes a bracket body 1010 , and the clamping device 100 is detachably connected to the bracket body 1010 via the bracket module 30 , and the bracket body 1010 fixes the electronic device.

[0104] It should be noted that the user can use the electronic device holder 101 on vehicles such as cars, bicycles, electric assisted bicycles and motorcycles, so that the user does not need to hold the electronic device all the time, freeing up both hands, greatly improving the safety during driving and reducing the probability of traffic accidents on the road.

[0105] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the principles of the present invention should be included in the protection scope of the present invention.
