[0008] Preferably, a first clamping structure and a second clamping structure are respectively provided at both ends of the supporting member in the length direction, and the first clamping structure and the second clamping structure respectively abut against the gear shaft in different directions.

[0009] Preferably, the supporting member is provided with a first limiting groove and a second limiting groove on one side close to the elastic member, and when the first limiting groove cooperates with the elastic member, the first clamping structure resists the gear shaft, and when the second limiting groove cooperates with the elastic member, the second clamping structure resists the gear shaft.

[0010] Preferably, a first limiting hole communicating with the outside is provided at the upper end of the shell, and a limiting column rotatably matched with the first limiting hole is provided on the upper end surface of the supporting member, and when the limiting column rotates to abut against the first limiting hole, the elastic member cooperates with the first limiting groove or the second limiting groove.

[0011] Preferably, the housing is provided with a second limiting hole at at least one end along the axial direction of the gear shaft, and the gear shaft is rotatably engaged with the housing through the second limiting hole.

[0012] Preferably, the gear shaft has a hollow channel, the fastener is partially accommodated in the hollow channel, the hollow channel is at least partially provided with an internal thread, and the fastener is provided with an external thread matching the internal thread in the length direction.

[0013] Preferably, a strip-shaped avoidance hole is provided in the length direction of the fixing clamp, and the fastener is movably matched with the avoidance hole.

[0014] Preferably, a clearance groove is provided at the connecting end of the fixed clamp and the movable clamp, and a clamping groove is provided at one end of the clearance groove away from the movable clamp;

[0015] The fixed clamp includes a rotating rod and an elastic element. The rotating rod is arranged in the giving way groove. The elastic element is sleeved on the rotating rod and located in the clamping groove. One end of the movable clamp extends into the giving way groove and is rotatably connected to the rotating rod.

[0016] In order to solve the above technical problems, the present invention provides another technical solution as follows: an electronic equipment bracket for placing electronic equipment, the electronic equipment bracket comprising the clamping device as described in any one of the above items.

[0017] Compared with the prior art, the clamping device and electronic equipment bracket provided by the present invention have the following beneficial effects:

[0018] 1. In a clamping device provided in an embodiment of the present invention, the clamping device includes a fixed clamp and a movable clamp that are rotatably connected. The fixed clamp and the movable clamp can cooperate to clamp the clamping device in locations such as a vehicle, an edge of a desktop, and a top of a TV. The relative positions of the fixed clamp and the movable clamp are fixed by a locking module, thereby fixing the clamping device on related equipment.

[0019] It can be understood that the elastic member enables the abutment member to abut and cooperate with the gear shaft in a specific direction, so that when the abutment member rotates along the abutment direction, the gear shaft is driven to rotate synchronously through the abutment cooperation with the gear shaft, and when the abutment member rotates along the non-abutment direction, the gear shaft drives the abutment member to deflect so that the abutment member slides along the outer periphery of the gear shaft, and the abutment member idles relative to the gear shaft, that is, the abutment member cannot drive the gear shaft to rotate in the non-abutment direction. Through this design, it can be prevented that outsiders can twist the locking module out of the external device through the shell, and then steal or destroy the related equipment, causing property loss to the user.

[0020] 2. In the clamping device provided in the embodiment of the present invention, the movable connecting section is rotatably connected to the fixed clamp, so that the size of the clamping gap between the movable clamp and the fixed clamp can be adjusted to accommodate devices of different sizes to be clamped; one end of the shell of the locking assembly is located at the end of the fixed clamp away from the movable clamp, and the fastener passes through the fixed clamp and is connected to the movable clamp. The fastener is driven to rotate through the shell, thereby driving the movable clamp to rotate relative to the fixed clamp to clamp the external device.

[0021] 3. In the clamping device provided in the embodiment of the present invention, the first clamping structure and the second clamping structure are abutted against the gear shaft in different directions, so that when different clamping structures cooperate with the gear shaft, the gear shaft is driven to rotate in different directions and cannot rotate in the opposite direction, thereby realizing that the fastener and the external device have two cooperation modes, namely, locking and detachable. While ensuring a good anti-theft effect of the locking module, the locking module can be removed from the relevant equipment when necessary.

[0022] 4. In the clamping device provided in the embodiment of the present invention, the abutting member, under the action of the elastic member, enables the first clamping structure or the second clamping structure to maintain an engagement state with the gear shaft, thereby preventing the abutting member from being disengaged from the gear shaft under the influence of external force, thereby causing the abutting member to be unable to drive the gear shaft to rotate; secondly, the elastic member and the abutting member are elastically matched, so that after the abutting member idles relative to the gear shaft, it can be reset to the abutting state with the gear shaft, so that the abutting member can continue to drive the gear shaft to rotate.

[0023] 5. In the clamping device provided in the embodiment of the present invention, the limiting column is partially accommodated in the first limiting hole connected to the outside world. The user can operate the limiting column through the first limiting hole, thereby controlling the first clamping structure or the second clamping structure to cooperate with the gear shaft, so that the abutting member can drive the gear shaft to rotate along a preset direction, thereby realizing the disassembly or locking of the fastener; when the limiting column is rotated to abut against the first limiting hole, the elastic member just cooperates with the first limiting groove or the second limiting groove. Through this design, the user can quickly and accurately rotate the abutting member to a state of cooperation with the elastic member, thereby improving the user's usage experience.

[0024] 6. In the clamping device provided in the embodiment of the present invention, the horizontal and vertical movements of the gear shaft are restricted by the second limiting hole, so that the gear shaft can only rotate along the predetermined center axis, thereby ensuring that the abutting member can always maintain an abutting state with the gear shaft when rotating, thereby improving the stability of the cooperation between the abutting member and the gear shaft.

[0025] 7. In the clamping device provided in the embodiment of the present invention, the fastener is threadedly matched with the gear shaft, so that when the gear shaft rotates, the fastener can be driven to rotate, so that the part of the fastener exposed in the hollow channel can be locked with or disengaged from the external device.

[0026] 8. In the clamping device provided in the embodiment of the present invention, a strip-shaped avoidance hole that cooperates with the fastener is provided in the length direction of the fixed clamp. It can be understood that when the movable clamp rotates relative to the fixed clamp, the corresponding point of the connection point between the movable clamp and the fastener relative to the fixed clamp will also change, thereby driving the fastener thereon to move. Through the design of the avoidance hole, when the movable clamp rotates, the fastener has space to move, thereby avoiding the rotation of the movable clamp being affected by the limited movement of the fastener.

[0027] 9. In the clamping device provided in the embodiment of the present invention, the movable clamp and the fixed clamp are rotatably connected via a rotating rod, so that the movable clamp can be rotated relative to the fixed clamp to adjust the size of the clamping opening between the movable clamp and the fixed clamp, thereby allowing the clamping device to be clamped on equipment of different sizes, thereby improving the applicability of the clamping device; the elastic element sleeved on the rotating rod can provide rotational tension for the movable clamp, so that the fixed clamp and the movable clamp can maintain the current clamping state.

[0028] 10. An electronic device bracket provided in an embodiment of the present invention is used for placing electronic devices, and the electronic device bracket comprises the clamping device as described in any one of the above items.

[0029] It can be understood that the electronic device bracket provided by the embodiment of the present invention has the same beneficial effects as the clamping device described in any one of the above items, which will not be described in detail here.

It should be particularly noted that each box in the block diagram and / or flow chart, and the combination of the boxes in the block diagram and / or flow chart can be implemented by a dedicated hardware-based system that performs a specified function or operation, or can be implemented by a combination of dedicated hardware and computer instructions.

[0056] See also Figure 1-6 The first embodiment of the present invention provides a clamping device 100, comprising a fixed clamp 20, a movable clamp 30 and a locking module 10; the fixed clamp 20 and the movable clamp 30 are rotatably connected, and the locking module 10 can movably penetrate the fixed clamp 20 on one side of the fixed clamp 20 and then be connected to the movable clamp 30; the locking module 10 comprises a housing 1, a locking assembly 2 and a fastener 3; the housing 1 has an accommodating cavity 11 inside, and the locking assembly 2 comprises a gear shaft 21, a holding member 22 and an elastic member arranged in the accommodating cavity 11 23, the gear shaft 21 and the supporting member 22 are rotatably matched with the housing 1, and the supporting member 22 is supported and matched with the gear shaft 21 through the elastic member 23; when the supporting member 22 is against the gear shaft 21, the housing 1 can only drive the gear shaft 21 to rotate along the supporting direction, and when the housing 1 is rotated along the non-supporting direction, the housing 1 is idle relative to the gear shaft 21; the supporting direction and the non-supporting direction are clockwise and the other is counterclockwise; one end of the fastener 3 is connected to the gear shaft 21, and the other end extends out of the accommodating cavity 11 and is connected to the movable clamp 30.

[0057] As a clamp for assisting in fixing electronic equipment, the clamping device 100 includes a fixed clamp 20 and a movable clamp 30 that are rotatably connected. The fixed clamp 20 and the movable clamp 30 can cooperate to clamp the clamping device 100 in locations such as vehicles, desktop edges, and the top of a television. The relative positions of the clamp 20 and the movable clamp 30 are fixed by a locking module 10, thereby fixing the clamping device 100 on the relevant equipment.

[0058] The clamping device 100 provided in this embodiment solves the problem of poor anti-theft effect of the existing clamping device 100 by connecting the fixed clamp 20 and the movable clamp 30 with a locking module 10 having an anti-theft function.

[0059] Specifically, the maximum rotation radius of the abutment 22 is greater than the minimum distance from the rotation axis of the abutment 22 to the outer circumference of the gear shaft 21. Therefore, when the abutment 22 rotates in the abutting direction, the abutment 22 is acted upon by the gear shaft 21, thereby clamping with the gear shaft 21, so that the abutment 22 can smoothly drive the gear shaft 21 to rotate; and when the abutment 22 rotates in the non-abutting reverse direction, the abutment 22 is disengaged from the gear shaft 21 under the action of the gear shaft 21, so that the abutment 22 cannot drive the gear shaft 21 to rotate in this direction.

[0060] It should be noted that the abutting direction of this embodiment refers to the direction of rotation from the line connecting the rotation axes of the gear shaft 21 and the abutting member 22 to the abutting position of the gear shaft 21 and the abutting member 22; the non-abutting direction refers to the direction opposite to the abutting direction.

[0061] It can be understood that the elastic member 23 enables the abutment member 22 to abut against the gear shaft 21 in a specific direction, so that when the abutment member 22 rotates in the abutting direction, the abutment member 22 and the gear shaft 21 drive the gear shaft 21 to rotate synchronously, and when the abutment member 22 rotates in the non-abutting direction, the gear shaft 21 drives the abutment member 22 to deflect so that the abutment member 22 slides along the outer periphery of the gear shaft 21, and the abutment member 22 idles relative to the gear shaft 21, that is, the abutment member 22 cannot drive the gear shaft 21 to rotate in the non-abutting direction.

[0062] It should be noted that the fastener 3 is connected to the gear shaft 21 , that is, when the gear shaft 21 rotates, the fastener 3 is driven to rotate, so that the fastener 3 and the movable clamp 30 are locked or disassembled.

[0063] The above design can prevent an outsider from screwing the locking module 10 out of the movable clamp 30 through the housing 1 and then stealing or destroying the clamping device 100 , thereby causing property loss to the user.

[0064] Optionally, the fastener 3 may be a bolt, a screw, a stud, or other mechanical connection structure that is fastened or disassembled by rotation, and no further limitation is given herein.

[0065] Furthermore, the movable clamp 30 includes a connected movable clamping section 301 and a movable connecting section 302, the movable connecting section 302 is rotatably connected to the fixed clamp 20, a limiting groove 303 is provided on the movable connecting section 302, a limiting member 304 is provided in the limiting groove 303, and the end of the fastener 3 away from the shell 1 is fixedly connected to the limiting member 304.

[0066] As a feasible implementation mode, after the fastener 3 passes through the fixed clamp 20 at one end away from the shell 1, it extends toward the movable connection section 302 and is connected to the limit member 304. By rotating the shell 1 to drive the fastener 3 to rotate, the movable clamp 30 is driven to rotate relative to the fixed clamp 20 to adjust the size of the clamp between the fixed clamp 20 and the movable clamp 30.

[0067] It can be understood that the movable connecting section 302 is rotatably connected to the fixed clamp 20, so that the size of the clamping gap between the movable clamp 30 and the fixed clamp 20 can be realized, so that the clamping device 100 can clamp devices of different sizes; one end of the shell 1 provided with the locking assembly 2 is located at the end of the fixed clamp 20 away from the movable clamp 30, the fastener 3 passes through the fixed clamp 20 and is connected to the movable clamp 30, and the fastener 3 is driven to rotate through the shell 1, thereby driving the movable clamp 30 to rotate relative to the fixed clamp 20 so that the clamping device 100 clamps the external device.

[0068] Please also refer to Figure 7 A first clamping structure 221 and a second clamping structure 222 are respectively provided at both ends of the supporting member 22 in the length direction. The first clamping structure 221 and the second clamping structure 222 respectively abut against the gear shaft 21 in different directions.

[0069] It should be noted that when the first clamping structure 221 and the second clamping structure 222 abut against the gear shaft 21, their contact points are respectively located on both sides of the line connecting the gear shaft 21 and the rotating axis of the abutting member 22, that is, when the first clamping structure 221 abuts against the gear shaft 21, the abutting direction defined in this embodiment is opposite to the abutting direction when the second clamping structure 222 abuts against the gear shaft 21.

[0070] As a feasible implementation, the first clamping structure 221 and the second clamping structure 222 are toothed structures that can mesh with the gear shaft 21 .

[0071] It can be understood that the first clamping structure 221 and the second clamping structure 222 abut against the gear shaft 21 in different directions, so that when different clamping structures cooperate with the gear shaft 21, the gear shaft 21 can be driven to rotate in different directions, and it cannot rotate in the opposite direction, thereby realizing that the fastener 3 and the movable clamp 30 have two cooperation modes, namely locking and detachable. While ensuring the good anti-theft effect of the locking module 10, the locking module 10 can also be removed from the movable clamp 30 when necessary.

[0072] Further, please refer to Figure 6 , Figure 7A first limiting groove 223 and a second limiting groove 224 are provided on the side of the supporting member 22 close to the elastic member 23. When the first limiting groove 223 cooperates with the elastic member 23, the first clamping structure 221 resists the gear shaft 21. When the second limiting groove 224 cooperates with the elastic member 23, the second clamping structure 222 resists the gear shaft 21.

[0073] Optionally, the abutting ends of the elastic member 23 and the abutting member 22 are spherical.

[0074] It should be noted that the first limiting groove 223 and the second limiting groove 224 are arranged in parallel on the side of the supporting member 22 close to the elastic member 23. When the first limiting groove 223 cooperates with the elastic member 23, the elastic member 23 supports the end of the first limiting groove 223 away from the second limiting groove 224, and there is a gap between the first limiting groove 223 and the end of the first limiting groove 223 close to the second limiting groove 224.

[0075] It can be understood that when the supporting member 22 rotates in the supporting direction, the first limiting groove 223 of the supporting member 22, under the action of the gear shaft 21, is away from the second limiting groove 224 and has a tendency to rotate toward the elastic member 23. Through this design, the supporting member 22 can more stably drive the gear shaft 21 to rotate; conversely, when the supporting member 22 rotates in the non-supporting direction, the first limiting groove 223 of the supporting member 22, under the action of the gear shaft 21, is close to the second limiting groove 224 and rotates toward the elastic member 23 to disengage the supporting member 22 from the gear shaft 21. Through this design, the supporting member 22 can rotate more smoothly to disengage the supporting member 22 from the gear shaft 21.

[0076] As an implementation manner, when the second limiting groove 224 cooperates with the elastic member 23 , the elastic member 23 presses against an end of the second limiting groove 224 away from the first limiting groove 223 , and a gap exists between the end of the second limiting groove 224 close to the first limiting groove 223 .

[0077] It can be understood that the cooperation mode between the second limiting groove 224 and the elastic member 23 is the same as the cooperation mode between the first limiting groove 223 and the elastic member 23, and the corresponding beneficial effects are also the same.

[0078] It can be understood that, under the action of the elastic member 23, the supporting member 22 keeps the first clamping structure 221 or the second clamping structure 222 in a meshing state with the gear shaft 21, thereby preventing the supporting member 22 from being disengaged from the gear shaft 21 under the influence of external force, thereby causing the supporting member 22 to be unable to drive the gear shaft 21 to rotate; secondly, the elastic member 23 and the supporting member 22 are elastically matched, so that the supporting member 22 can be reset to the abutting state with the gear shaft 21 after idling relative to the gear shaft 21, so that the supporting member 22 can continue to drive the gear shaft 21 to rotate.

[0079] For further information, please also refer to Figure 8A first limiting hole 12 communicating with the outside is provided at the upper end of the shell 1, and a limiting column 225 rotatably matched with the first limiting hole 12 is provided on the upper end surface of the abutting member 22. When the limiting column 225 rotates to abut against the first limiting hole 12, the elastic member 23 cooperates with the first limiting groove 223 or the second limiting groove 224.

[0080] Optionally, the supporting member 22 and the limiting column 225 are integrally formed.

[0081] As a feasible implementation mode, the first limiting hole 12 matches the shape of the limiting column 225, and it is not circular. The rotatable angle between the limiting column 225 and the first limiting hole 12 is less than 360 degrees. That is, when the limiting column 225 rotates clockwise or counterclockwise to a certain angle in the first limiting hole 12, it will abut against the inner wall of the first limiting hole 12 and cannot continue to rotate.

[0082] Specifically, when the limiting column 225 rotates clockwise to abut against the first limiting hole 12, the elastic member 23 is just in a state of abutting and cooperating with the first limiting groove 223, so that the first clamping structure 221 is engaged with the gear shaft 21, and the abutting member 22 can stably drive the gear shaft 21 to rotate along the preset direction.

[0083] It should be understood that when the limiting column 225 rotates counterclockwise to abut against the first limiting hole 12, the elastic member 23 is just in a state of abutting and cooperating with the second limiting groove 224, so that the second clamping structure 222 is engaged with the gear shaft 21, and then the abutting member 22 can stably drive the gear shaft 21 to rotate along another preset direction.

[0084] With this design, the user can precisely adjust the rotation angle of the abutment 22 without observing the rotation state of the abutment 22 , so that the abutment 22 can mesh with the gear shaft 21 , thereby smoothly driving the gear shaft 21 to rotate.

[0085] Specifically, the locking module 10 is placed in the disassembly mode or the anti-theft mode by the abutment between the limiting column 225 and the first limiting hole 12 in different directions.

[0086] It can be understood that the limiting column 225 is partially accommodated in the first limiting hole 12 connected to the outside world. The user can operate the limiting column 225 through the first limiting hole 12, thereby controlling the first clamping structure 221 or the second clamping structure 222 to cooperate with the gear shaft 21, so that the supporting member 22 can drive the gear shaft 21 to rotate along a preset direction, thereby realizing the disassembly or locking of the fastener 3.

[0087] Specifically, when the limiting column 225 rotates to abut against the first limiting hole 12, the elastic member 23 just cooperates with the first limiting groove 223 or the second limiting groove 224. Through this design, the user can quickly and accurately rotate the abutting member 22 to a state of cooperation with the elastic member 23, thereby improving the user's experience.

[0088] Further, please refer to Figure 3 The upper surface of the first limiting hole 12 is higher than the upper surface of the limiting column 225 , and a polygonal rotating structure 226 is provided on the upper surface of the limiting column 225 .

[0089] It should be noted that the upper surface of the first limiting hole 12 is higher than the upper surface of the limiting column 225 , that is, the limiting column 225 is completely received in the first limiting hole 12 without any part exposed to the outside.

[0090] This design makes it impossible for outsiders to operate the limiting column 225 without damaging the housing 1 , thereby switching the locking module 10 between the disassembly mode and the anti-theft mode, thereby improving the anti-theft effect of the locking module 10 .

[0091] It should be further explained that the rotating structure 226 can be a polygonal protrusion or groove provided on the upper surface of the limiting column 225 .

[0092] Optionally, the rotating structure 226 can be configured as a triangle, a quadrilateral, a hexagon, or other irregular shapes, which can be configured according to actual conditions.

[0093] As a feasible implementation, the rotating structure 226 is a hexagonal groove that cooperates with an Allen wrench, that is, a corresponding model of Allen wrench is required to operate the rotating structure 226, so that the supporting member 22 rotates a corresponding angle to put the locking module 10 in a disassembly mode or an anti-theft mode.

[0094] It can be understood that the rotating structure 226 on the limiting column 225 is a polygon, which requires a specific tool that matches the shape of the rotating structure 226 to cooperate with the rotating structure 226 to rotate the supporting member 22, thereby putting the locking module 10 in disassembly mode or anti-theft mode.

[0095] This design can effectively prevent outsiders from rotating the limit column 225 to switch the disassembly mode or anti-theft mode of the locking module 10 without using tools or only using tools collected at hand, thereby ensuring a good anti-theft effect.

[0096] For further information, see Figure 6 and Fig. 9 The housing 1 is provided with a second limiting hole 13 at least at one end along the axial direction of the gear shaft 21 , and the gear shaft 21 is rotatably matched with the housing 1 through the second limiting hole 13 .

[0097] As a feasible implementation mode, the shell 1 is provided with a second limiting hole 13 connected to the outside world at both axial ends of the gear shaft 21. The gear shaft 21 includes a connected gear part 214 and a rotating part 215. The rotating part 215 is located at both axial ends of the gear part 214, and the second limiting hole 13 is rotatably matched with the rotating part 215.

[0098] Specifically, the size of the second limiting hole 13 matches the rotating part 215 , the rotating part 215 is sleeved in the second limiting hole 13 , and the end surface of the gear part 214 abuts against the end surface of the second limiting hole 13 close to the gear part 214 .

[0099] The second limiting hole 13 is designed to restrict the horizontal and vertical movement of the gear shaft 21, so that the gear shaft 21 can only rotate along a predetermined center axis, thereby ensuring that the abutting member 22 can always maintain an abutting state with the gear shaft 21 when rotating, thereby improving the stability of the cooperation between the abutting member 22 and the gear shaft 21.

[0100] In a specific embodiment, a baffle 15 is provided on the second limiting hole 13 arranged at one end of the shell 1 away from the fastener 3, and the baffle 15 is used to cover the second limiting hole 13 at that location, thereby preventing the fastener 3 from detaching from the gear shaft 21 at the second limiting hole 13.

[0101] Optionally, the second limiting hole 13 on the end of the housing 1 away from the fastener 3 can be configured not to communicate with the outside.

[0102] As another feasible embodiment, a second limiting hole 13 connected to the outside is provided at one end of the shell 1 close to the fastener 3, the end of the gear shaft 21 close to the second limiting hole 13 is a rotating part 215, and the end away from the second limiting hole 13 is a gear part 214, and the fastener 3 extends from the second limiting hole 13 to the outside of the shell 1.

[0103] For further information, see Fig.10 and Fig.11 The gear shaft 21 has a hollow channel 211 , at least part of the hollow channel 211 is provided with an internal thread 213 , and the fastener 3 is provided with an external thread 31 matching the internal thread 213 in the length direction.

[0104] It should be noted that the fastener 3 passes through the gear shaft 21 through the hollow channel 211 and is threadedly connected to the gear shaft 21 on the inner wall of the hollow channel 211, so that when the gear shaft 21 rotates, the fastener 3 can be driven to rotate, and the part of the fastener 3 exposed in the hollow channel 211 can be locked or disengaged with the movable clamp 30.

[0105] Furthermore, the fastener 3 is partially accommodated in the hollow channel 211 , a first limiting structure 212 is provided on the inner wall of the hollow channel 211 , and a second limiting structure 32 cooperating with the first limiting structure 212 is provided at one end of the hollow channel 211 where the fastener 3 is accommodated.

[0106] As a feasible implementation, the first limiting structure 212 is an annular protrusion arranged on the inner wall of the hollow channel 211, and the internal thread 213 is arranged on the inner wall of the first limiting structure 212. The fastener 3 is threadedly matched with the internal thread 213 on the first limiting structure 212 through the external thread 31 thereon, so that the fastener 3 is connected to the gear shaft 21.

[0107] The fastener 3 is accommodated in a second limiting structure 32 at one end of the hollow channel 211. When the fastener 3 and the gear shaft 21 rotate relative to each other, the second limiting structure 32 approaches or moves away from the first limiting structure 212. When the fastener 3 rotates to the point where the second limiting structure 32 conflicts with the first limiting structure 212, the first limiting structure 212 restricts the fastener 3 from continuing to rotate in this direction, thereby preventing the gear shaft 21 from excessively rotating and causing the fastener 3 to disengage from the gear shaft 21.

[0108] Furthermore, a third limiting groove 14 is provided on the inner wall of the housing 1 , and the elastic member 23 is fixedly matched with the housing 1 through the third limiting groove 14 .

[0109] It can be understood that the elastic member 23 is partially accommodated in the third limiting groove 14, and the movement of the elastic member 23 in the shell 1 is limited by the third limiting groove 14, so that the elastic member 23 and the shell 1 are relatively fixed, and then when the elastic member 23 cooperates with the supporting member 22, the supporting member 22 can also maintain a corresponding positioning state, so that it can better drive the gear shaft 21 to rotate.

[0110] Optionally, the elastic member 23 is fixedly disposed on the housing 1 .

[0111] Furthermore, a strip-shaped avoidance hole 201 is provided in the length direction of the fixing clamp 20 , and the fastener 3 is movably matched with the avoidance hole 201 .

[0112] It can be understood that when the movable clamp 30 rotates relative to the fixed clamp 20, the corresponding point of the connection point between the movable clamp 30 and the fastener 3 relative to the fixed clamp 20 will also change, thereby causing the fastener 3 thereon to be displaced. By designing the avoidance hole 201, when the movable clamp 30 rotates, there is space for the fastener 3 to move, thereby preventing the rotation of the movable clamp 30 from being affected by the limited movement of the fastener 3.

[0113] For further information, see Fig.12 A clearance groove 202 is provided at the connection end between the fixed clamp 20 and the movable clamp 30, and a clamping groove 203 is provided at the end of the clearance groove 202 away from the movable clamp 30;

[0114] The fixed clamp 20 includes a rotating rod 204 and an elastic element 205. The rotating rod 204 is arranged in the clearance groove 202. The elastic element 205 is sleeved on the rotating rod 204 and located in the clamping groove 203. One end of the movable clamp 30 extends into the clearance groove 202 and is rotatably connected to the rotating rod 204.

[0115] Optionally, the elastic element 205 is a torsion spring.

[0116] In the clamping device 100 provided in this embodiment, the rotating rod 204 connects the movable chuck 30 with the fixed chuck 20, so that the movable chuck 30 can be rotatably connected with the fixed chuck 20. The elastic element 205 sleeved on the rotating rod 204 can provide steering tension for the movable chuck 30, so that the fixed chuck and the movable chuck can maintain the current clamping state.

[0117] It can be understood that the movable clamp 30 and the fixed clamp 20 are rotatably connected via the rotating rod 204, so that the movable clamp 30 can be rotated relative to the fixed clamp 20 to adjust the size of the clamping opening between the movable clamp 30 and the fixed clamp 20, thereby allowing the clamping device 100 to be clamped on devices of different sizes, thereby improving the applicability of the clamping device 100.

[0118] For further information, see Fig.13 The second embodiment of the present invention further provides an electronic device bracket 200 for placing electronic devices. The electronic device bracket 200 includes the above-mentioned clamping device 100.

[0119] It can be understood that the electronic device bracket 200 of this embodiment has the same beneficial effects as the clamping device 100 of the above-mentioned embodiment, and the electronic devices include but are not limited to microphones, cameras, mobile phones, and tablet computers.

[0120] In some embodiments, the electronic device bracket 200 generally further includes a bracket body 300 , which is detachably or fixedly connected to the clamping device 100 , and the bracket body 300 is used to fix the electronic device.

[0121] It should be noted that the user can use the electronic device holder 200 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 safety during driving and reducing the probability of traffic accidents on the road.

[0122] Compared with the prior art, the clamping device and electronic equipment bracket provided by the present invention have the following beneficial effects:

[0123] 1. In a clamping device provided in an embodiment of the present invention, the clamping device includes a fixed clamp and a movable clamp that are rotatably connected. The fixed clamp and the movable clamp can cooperate to clamp the clamping device in locations such as a vehicle, an edge of a desktop, and a top of a TV. The relative positions of the fixed clamp and the movable clamp are fixed by a locking module, thereby fixing the clamping device on related equipment.

[0124] It can be understood that the elastic member enables the abutment member to abut and cooperate with the gear shaft in a specific direction, so that when the abutment member rotates along the abutment direction, the gear shaft is driven to rotate synchronously through the abutment cooperation with the gear shaft, and when the abutment member rotates along the non-abutment direction, the gear shaft drives the abutment member to deflect so that the abutment member slides along the outer periphery of the gear shaft, and the abutment member idles relative to the gear shaft, that is, the abutment member cannot drive the gear shaft to rotate in the non-abutment direction. Through this design, it can be prevented that outsiders can twist the locking module out of the external device through the shell, and then steal or destroy the related equipment, causing property loss to the user.

[0125] 2. In the clamping device provided in the embodiment of the present invention, the movable connecting section is rotatably connected to the fixed clamp, so that the size of the clamping gap between the movable clamp and the fixed clamp can be adjusted to accommodate devices of different sizes to be clamped; one end of the shell of the locking assembly is located at the end of the fixed clamp away from the movable clamp, and the fastener passes through the fixed clamp and is connected to the movable clamp. The fastener is driven to rotate through the shell, thereby driving the movable clamp to rotate relative to the fixed clamp to clamp the external device.

[0126] 3. In the clamping device provided in the embodiment of the present invention, the first clamping structure and the second clamping structure are abutted against the gear shaft in different directions, so that when different clamping structures cooperate with the gear shaft, the gear shaft is driven to rotate in different directions and cannot rotate in the opposite direction, thereby realizing that the fastener and the external device have two cooperation modes, namely, locking and detachable. While ensuring a good anti-theft effect of the locking module, the locking module can be removed from the relevant equipment when necessary.

[0127] 4. In the clamping device provided in the embodiment of the present invention, the abutting member, under the action of the elastic member, enables the first clamping structure or the second clamping structure to maintain an engagement state with the gear shaft, thereby preventing the abutting member from being disengaged from the gear shaft under the influence of external force, thereby causing the abutting member to be unable to drive the gear shaft to rotate; secondly, the elastic member and the abutting member are elastically matched, so that after the abutting member idles relative to the gear shaft, it can be reset to the abutting state with the gear shaft, so that the abutting member can continue to drive the gear shaft to rotate.

[0128] 5. In the clamping device provided in the embodiment of the present invention, the limiting column is partially accommodated in the first limiting hole connected to the outside world. The user can operate the limiting column through the first limiting hole, thereby controlling the first clamping structure or the second clamping structure to cooperate with the gear shaft, so that the abutting member can drive the gear shaft to rotate along a preset direction, thereby realizing the disassembly or locking of the fastener; when the limiting column is rotated to abut against the first limiting hole, the elastic member just cooperates with the first limiting groove or the second limiting groove. Through this design, the user can quickly and accurately rotate the abutting member to a state of cooperation with the elastic member, thereby improving the user's usage experience.

[0129] 6. In the clamping device provided in the embodiment of the present invention, the horizontal and vertical movements of the gear shaft are restricted by the second limiting hole, so that the gear shaft can only rotate along the predetermined center axis, thereby ensuring that the abutting member can always maintain an abutting state with the gear shaft when rotating, thereby improving the stability of the cooperation between the abutting member and the gear shaft.

[0130] 7. In the clamping device provided in the embodiment of the present invention, the fastener is threadedly matched with the gear shaft, so that when the gear shaft rotates, the fastener can be driven to rotate, so that the part of the fastener exposed in the hollow channel can be locked with or disengaged from the external device.

[0131] 8. In the clamping device provided in the embodiment of the present invention, a strip-shaped avoidance hole that cooperates with the fastener is provided in the length direction of the fixed clamp. It can be understood that when the movable clamp rotates relative to the fixed clamp, the corresponding point of the connection point between the movable clamp and the fastener relative to the fixed clamp will also change, thereby driving the fastener thereon to move. Through the design of the avoidance hole, when the movable clamp rotates, the fastener has space to move, thereby avoiding the rotation of the movable clamp being affected by the limited movement of the fastener.

[0132] 9. In the clamping device provided in the embodiment of the present invention, the movable clamp and the fixed clamp are rotatably connected via a rotating rod, so that the movable clamp can be rotated relative to the fixed clamp to adjust the size of the clamping opening between the movable clamp and the fixed clamp, thereby allowing the clamping device to be clamped on equipment of different sizes, thereby improving the applicability of the clamping device; the elastic element sleeved on the rotating rod can provide rotational tension for the movable clamp, so that the fixed clamp and the movable clamp can maintain the current clamping state.

[0133] 10. An electronic device bracket provided in an embodiment of the present invention is used for placing electronic devices, and the electronic device bracket comprises the clamping device as described in any one of the above items.

[0134] It can be understood that the electronic device bracket provided by the embodiment of the present invention has the same beneficial effects as the clamping device described in any one of the above items, which will not be described in detail here.

[0135] The above is a detailed introduction to a clamping device and an electronic device bracket disclosed in an embodiment of the present invention. Specific examples are used in this article to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method of the present invention and its core idea; at the same time, for general technical personnel in this field, according to the idea of ​​the present invention, there will be changes in the specific implementation method and application scope. In summary, the content of this specification should not be understood as a limitation on the present invention.
