[0006] The first clamping arm, the transmission block, and the second clamping arm are stacked sequentially within the housing, and the transmission block is engaged with the second clamping arm; the transmission block is symmetrically provided with a first rack and a second rack extending along the length direction on one side facing the first clamping arm, and the first clamping arm is provided with a third rack and a fourth rack respectively corresponding to the first rack and the second rack; a first transmission gear meshes between the first rack and the third rack, and a second transmission gear meshes between the second rack and the fourth rack.

[0007] Preferably, a first groove is formed on the first clamping arm corresponding to the transmission block, and a second groove is formed on the second clamping arm corresponding to the transmission block. The first groove and the second groove together form a receiving cavity, and the transmission block is disposed in the receiving cavity.

[0008] Preferably, the transmission assembly further includes an adjustment knob and a threaded rod. The transmission block has a strip groove along its length, and a threaded component is embedded in the strip groove. One end of the threaded rod is placed in the strip groove and threadedly connected to the threaded component, while the other end extends out of the housing and is connected to the adjustment knob.

[0009] Preferably, the transmission assembly further includes a locking member, the second clamping arm has a slot, the transmission block passes through the slot out of the housing and is rotatably connected to the locking member; the transmission block has a limiting step in the housing near the slot, the width of the limiting step is greater than the width of the slot.

[0010] Preferably, the locking component includes an eccentric wheel and a lever, the eccentric wheel has a first through hole, the end of the transmission block has a second through hole, and a rotating shaft is provided in the first through hole and the second through hole.

[0011] Preferably, the housing includes a detachably connected upper housing and a lower housing. A first fixing post and a second fixing post are provided on the inner wall of the lower housing. A first clearance groove and a second clearance groove are provided on the second clamping arm. The first fixing post passes through the first clearance groove and is rotatably connected to the first transmission gear. The second fixing post passes through the second clearance groove and is rotatably connected to the second transmission gear.

[0012] Preferably, the top surface of the transmission block is provided with at least one sliding block, and the first clamping arm is provided with at least one sliding groove corresponding to the sliding block, and the sliding block extends into the sliding groove.

[0013] Preferably, an elastic element is provided between the first clamping arm and the second clamping arm, and the two ends of the elastic element abut against the first clamping arm and the second clamping arm, respectively.

[0014] Preferably, there are two elastic elements. Two positioning blind holes are symmetrically arranged on the second clamping arm along the width direction. One end of the elastic element is located in the positioning blind hole, and the other end abuts against the second clamping arm.

[0015] To solve the above-mentioned technical problems, this utility model provides another technical solution as follows: a bracket, including a support structure and the above-mentioned clamping assembly, wherein the clamping assembly and the support structure are fixedly connected or movably connected.

[0016] Compared with the prior art, the clamping assembly and bracket provided by this utility model have the following beneficial effects:

[0017] 1. The clamping assembly provided in this embodiment of the present invention, in which the first clamping arm, the transmission block, and the second clamping arm are stacked sequentially within the housing, effectively saves space and improves the compactness of the assembly. The first and second racks are symmetrically arranged on both sides of the transmission block. The first transmission gear meshes between the first and third racks, and the second transmission gear meshes between the second and fourth racks. When the transmission block slides along its length, the first clamping arm moves in the opposite direction to the transmission block. Simultaneously, because the transmission block engages with the second clamping arm, it can directly drive the second clamping arm to move, achieving synchronous opening and closing of the first and second clamping arms. This design ensures that the transmission of the first clamping arm is achieved through the combined action of two sets of symmetrical racks and transmission gears, guaranteeing uniform force on both sides of the first clamping arm and reducing errors and uneven friction caused by unilateral transmission. This makes the first clamping arm more stable, smooth, and precise during operation, avoiding deviation or jamming.

[0018] 2. In the clamping assembly provided in this embodiment of the present invention, a first groove is formed on the first clamping arm corresponding to the transmission block, and a second groove is formed on the second clamping arm corresponding to the transmission block. The first and second grooves together form a receiving cavity, and the transmission block is disposed within the receiving cavity. The first and second grooves are used to limit and guide the transmission block, ensuring that the transmission block can only slide along its length direction. This makes the force on the transmission block more uniform, enabling it to move more stably and avoiding jamming.

[0019] 3. The clamping assembly provided in this embodiment of the present invention includes an adjustment knob and a threaded rod. The transmission block has a strip-shaped groove along its length, and a threaded component is embedded within the groove. One end of the threaded rod is placed in the strip-shaped groove and threadedly connected to the threaded component, while the other end extends out of the housing and is connected to the adjustment knob. By rotating the adjustment knob, the threaded rod and the threaded component can be moved relative to each other. The threaded component, embedded in the strip-shaped groove, further drives the entire transmission block and the threaded rod to move relative to each other, achieving synchronous opening and closing of the first and second clamping arms. Through the threaded rotational connection, the degree of opening and closing between the first and second clamping arms can be precisely adjusted, ensuring that the clamping assembly is suitable for electronic products of various sizes. Placing the threaded rod in the strip-shaped groove guides and limits its movement. The threaded rod moves smoothly along the strip-shaped groove, effectively limiting its degree of freedom and preventing unnecessary offset or shaking, further ensuring the stability of the opening and closing of the first and second clamping arms.

[0020] 4. The clamping assembly provided in this embodiment of the present invention includes a locking component in the transmission assembly. The second clamping arm has a slot, through which the transmission block passes through the slot and is rotatably connected to the locking component. A limiting step is provided on the transmission block inside the housing near the slot, the width of which is greater than the width of the slot. The locking component securely locks the transmission block in its current state, preventing accidental loosening or displacement. The design of the limiting step not only allows the second clamping arm to open outwards but also limits the range of motion of the transmission block when locked by the locking component, preventing the transmission block from dislodging or becoming misaligned.

[0021] 5. The clamping assembly provided in this embodiment of the present invention includes an eccentric wheel and a lever. The eccentric wheel has a first through hole, and the end of the transmission block has a second through hole. A rotating shaft is disposed within the first and second through holes. The eccentric wheel and the transmission block are rotatably connected via the rotating shaft. The rotation of the eccentric wheel causes its center position to shift, thereby generating a large torque between the rotating shaft and the transmission block. This allows for precise locking and adjustment of the clamping arm through adjustment of the eccentric wheel. The lever further simplifies operation, allowing for quick unlocking or locking when needed, thus facilitating adjustment and operation.

[0022] 6. The clamping assembly provided in this embodiment of the present invention includes a detachably connected upper housing and a lower housing. A first fixing post and a second fixing post are provided on the inner wall of the lower housing. A first clearance groove and a second clearance groove are provided on the second clamping arm. The first fixing post passes through the first clearance groove and is rotatably connected to the first transmission gear, and the second fixing post passes through the second clearance groove and is rotatably connected to the second transmission gear. The design of the first and second fixing posts ensures that the transmission gear rotates only relative to the fixing posts during transmission, without displacement, thus ensuring the stability of the transmission gear's position during operation and preventing transmission failure due to loosening or displacement of the transmission gear.

[0023] 7. In the clamping assembly provided in this embodiment of the present invention, at least one sliding block is protruding from the top surface of the transmission block, and at least one sliding groove is provided on the first clamping arm corresponding to the sliding block, with the sliding block extending into the sliding groove. The cooperative design of the sliding block and the sliding groove enables the transmission block to slide smoothly and steadily during operation, ensuring that it always remains in the correct position and avoiding transmission errors or poor gear meshing caused by component misalignment.

[0024] 8. In the clamping assembly provided in this embodiment of the present invention, an elastic element is provided between the first clamping arm and the second clamping arm, with both ends of the elastic element abutting against the first clamping arm and the second clamping arm, respectively. When the locking member locks, the force is first applied to the second clamping arm. Because of the elastic deformation of the elastic element, this force is concentrated on the second clamping arm, thereby achieving the locking of the second clamping arm. The first clamping arm, because it abuts against the elastic element, is not directly subjected to the locking force and therefore does not move synchronously, allowing the locking member to achieve more precise locking and maintaining clamping stability.

[0025] 9. In the clamping assembly provided in this embodiment of the present invention, two elastic elements are provided. Two positioning blind holes are symmetrically arranged along the width direction on the second clamping arm. One end of each elastic element is located within a positioning blind hole, and the other end abuts against the second clamping arm. This design allows the force generated when the locking element is engaged to be evenly distributed between the two elastic elements, preventing the first clamping arm from shifting to one side due to uneven force distribution, thus improving overall stability. The design of one end of the elastic element being located within a positioning blind hole and the other end abutting against the second clamping arm effectively limits excessive displacement and deformation of the elastic element, increasing its reliability and lifespan.

[0026] 10. This utility model embodiment also provides a bracket, which has the same beneficial effects as the clamping component described above, and will not be described in detail here. Attached Figure Description

[0046] Furthermore, in addition to indicating direction or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this utility model according to the specific circumstances.

[0047] Furthermore, the terms "installation," "setup," "equipped with," "connection," and "linked" should be interpreted broadly.

Those skilled in the art can understand the specific meaning of these terms in this utility model based on the specific circumstances.

[0048] Please see Figures 1 to 5 The first embodiment of this utility model provides a clamping assembly 1, including a housing 10, a transmission assembly 20, a first clamping arm 30, and a second clamping arm 40, with the first clamping arm 30 and the second clamping arm 40 partially disposed within the housing 10. The transmission assembly 20 includes a transmission block 200 and a first transmission gear 201 and a second transmission gear 202 disposed on both sides of the transmission block 200. The first clamping arm 30, the transmission block 200, and the second clamping arm 40 are sequentially stacked within the housing 10, and the transmission block 200 is engaged with the second clamping arm 40.

[0049] Understandably, the first clamping arm 30, the transmission block 200, and the second clamping arm 40 are stacked within the housing 10, which can effectively save space and improve the compactness of the components.

[0050] Specifically, the first clamping arm 30 includes a first clamping portion 300 and a first transmission portion 301 connected to the first clamping portion 300, and the second clamping arm 40 includes a second clamping portion 400 and a second transmission portion 401 connected to the second clamping portion 400. The first clamping portion 300 and the second clamping portion 400 cooperate to clamp electronic devices. The first transmission portion 301 includes a first part 302 connected to the first clamping portion 300 and a second part 303 arranged perpendicularly to the first part 302; the second transmission portion 401 includes a third part 402 connected to the second clamping portion 400 and a fourth part 403 arranged perpendicularly to the third part 402. Openings 102 are correspondingly provided on the two side walls of the housing 10, and the second part 303 and the fourth part 403 extend into the interior of the housing 10 through the openings 102, and the second part 303, the transmission block 200 and the fourth part 403 are arranged in a stacked manner. The first clamping part 300 and the second clamping part 400 are also provided with an anti-slip structure 304 to increase the friction between the clamping part and the clamped electronic device, prevent the clamped object from sliding or loosening during the clamping process, and ensure a more secure and reliable clamping effect. The anti-slip structure 304 can be an independent elastic anti-slip component, or it can be a textured surface integrally formed with the first clamping part 300 and the second clamping part 400.

[0051] Understandably, the transmission block 200 engages with the second clamping arm 40. Specifically, matching engagement structures can be provided on the transmission block 200 and the second clamping arm 40 to ensure that the transmission block 200 can drive the second clamping arm 40 to move synchronously. In this embodiment, the specific shape of the engagement structure is not limited.

[0052] Furthermore, the transmission block 200 has a first rack 203 and a second rack 204 symmetrically arranged on adjacent side surfaces facing the first clamping arm 30, extending along the length direction. The first clamping arm 30 has a third rack 305 and a fourth rack 306 respectively corresponding to the first rack 203 and the second rack 204. The first transmission gear 201 meshes between the first rack 203 and the third rack 305, and the second transmission gear 202 meshes between the second rack 204 and the fourth rack 306.

[0053] Understandably, when the transmission block 200 slides along its length, the first clamping arm 30 and the transmission block 200 can move in opposite directions due to the transmission of the first transmission gear 201 and the second transmission gear 202; at the same time, since the transmission block 200 is engaged with the second clamping arm 40, it can directly drive the second clamping arm 40 to move, so the first clamping arm 30 and the second clamping arm 40 can achieve synchronous opening and closing.

[0054] Understandably, this design ensures that the transmission of the first clamping arm 30 is achieved through the combined action of two sets of symmetrical racks and transmission gears. This guarantees uniform force distribution on both sides of the first clamping arm 30, reducing errors and uneven friction caused by unilateral transmission. This makes the first clamping arm 30 operate more smoothly, steadily, and precisely, preventing deviation or jamming. The second clamping arm 40 engages with the transmission block 200, moving synchronously with it, further ensuring the stability of the movement during transmission and preventing loosening or misalignment.

[0055] Furthermore, a first groove 307 is provided on the first clamping arm 30 corresponding to the transmission block 200, and a second groove 404 is provided on the second clamping arm 40 corresponding to the transmission block 200. The first groove 307 and the second groove 404 enclose a receiving cavity, and the transmission block 200 is disposed in the receiving cavity.

[0056] Understandably, the first groove 307 and the second groove 404 are used to limit and guide the transmission block 200, ensuring that the transmission block 200 can only slide along its length. This makes the force on the transmission block 200 more even, enabling it to move more stably and avoiding jamming. It also allows for the efficient use of the space between the transmission block 200 and the clamping arm, avoiding unnecessary gaps and making the entire structure more compact.

[0057] Specifically, the third rack 305 and the fourth rack 306 on the first clamping arm 30 are disposed on the inner wall of the first groove 307 along its length. When the transmission block 200 engages with the first groove 307, the first rack 203 is opposite to the third rack 305, and the second rack 204 is opposite to the fourth rack 306. The first transmission gear 201 and the second transmission gear 202 are also disposed within the first groove 307, stably transmitting power to the transmission block 200 and the first clamping arm 30.

[0058] Please combine Figure 5 and Figure 6 Furthermore, the transmission assembly 20 also includes an adjustment knob 205 and a threaded rod 206. The transmission block 200 has a strip groove 207 along its length. A threaded component 209 is embedded in the strip groove 207. One end of the threaded rod 206 is placed in the strip groove 207 and threadedly connected to the threaded component 209. The other end extends out of the housing 10 and is connected to the adjustment knob 205.

[0059] Understandably, the threaded part 209 has a threaded hole, and the threaded rod 206 extends into the threaded hole and is threadedly connected to the threaded part 209. By rotating the adjustment knob 205, the threaded rod 206 can be rotated to generate relative displacement with the threaded part 209. Since the threaded part 209 is embedded in the strip groove 207, the threaded part 209 can drive the entire transmission block 200 to generate relative displacement with the screw. The transmission block 200 further drives the first clamping arm 30 and the second clamping arm 40 to open and close synchronously.

[0060] Understandably, the opening and closing degree between the first clamping arm 30 and the second clamping arm 40 can be precisely adjusted through the threaded rotation connection, ensuring that the clamping assembly 1 can be used for electronic products of various sizes. The strip groove 207 can guide and limit the threaded rod 206. The threaded rod 206 moves smoothly along the strip groove 207, effectively restricting the degree of freedom of the threaded rod 206, preventing unnecessary offset or shaking, and further ensuring the stability of the opening and closing of the first clamping arm 30 and the second clamping arm 40.

[0061] Understandably, in this embodiment, the position of the slot 207 is not limited, as long as it does not interfere with other components. The shape of the threaded component 209 is also not limited; it can be a separate component embedded in the slot 207 or integrally formed with the transmission block 200. As a specific example, the slot 207 is located on the side of the transmission block 200 facing the second clamping arm 40, along the length of the transmission block 200, and the central axis of the slot 207 coincides with the central axis of the transmission block 200. The threaded component 209 is a standard square nut, and a slot 208 is provided in the slot 207 near the first end of the threaded knob, in which the threaded component 209 is engaged.

[0062] Please combine Figure 2 , Figure 6 and Figure 7 Furthermore, the transmission assembly 20 also includes a locking member 210. The second clamping arm 40 has a slot 405. The transmission block 200 passes through the slot 405 and extends out of the housing 10 and is rotatably connected to the locking member 210. The transmission block 200 has a limiting step 211 in the housing 10 near the slot 405. The width of the limiting step 211 is greater than the width of the slot 405.

[0063] Understandably, the locking element 210 is used to securely lock the transmission block 200 in its current state, preventing accidental loosening or displacement of the transmission block 200. The design of the limiting step 211 not only allows the second clamping arm 40 to open outward away from the first clamping arm 30, but also limits the range of motion of the transmission block 200 when locking with the locking element 210, preventing the transmission block 200 from coming off or becoming misaligned.

[0064] As a specific example, the transmission block 200 is also provided with a first step 212, and the second groove 404 of the second clamping arm 40 is correspondingly provided with a second step 406. The first step 212 and the second step 406 cooperate to enable the transmission block 200 to drive the second clamping arm 40 to move closer to the first clamping arm 30 and lock it inward.

[0065] Furthermore, the locking member 210 includes an eccentric wheel 213 and a lever part 214. The eccentric wheel 213 has a first through hole 215, and the end of the transmission block 200 has a second through hole 216. A rotating shaft 217 is provided in the first through hole 215 and the second through hole 216.

[0066] Understandably, the eccentric wheel 213 and the transmission block 200 are rotatably connected via the rotating shaft 217. The rotation of the eccentric wheel 213 causes its center position to shift, thereby generating a large torque between the rotating shaft 217 and the transmission block 200. This allows for precise locking and adjustment of the clamping arm through adjustment of the eccentric wheel 213, ensuring that the electronic equipment is reliably clamped.

[0067] Understandably, the cooperation of the actuating part 214 makes operation simpler, allowing for quick unlocking or locking when needed, thus facilitating adjustment and operation. In this embodiment, the specific shape of the actuating part 214 is not limited, as long as it is convenient for the user to actuate, driving the eccentric wheel 213 to rotate to achieve locking and unlocking.

[0068] Furthermore, an elastic element 103 is provided between the first clamping arm 30 and the second clamping arm 40, and the two ends of the elastic element 103 abut against the first clamping arm 30 and the second clamping arm 40 respectively.

[0069] Understandably, when the locking member 210 locks, the force first acts on the second clamping arm 40. The elastic deformation of the elastic member 103 concentrates this force on the second clamping arm 40, thus locking it. The first clamping arm 30, while in contact with the elastic member 103, is not directly subjected to the locking force and therefore does not move synchronously. This allows the locking member 210 to achieve more precise locking and maintain clamping stability.

[0070] Furthermore, there are two elastic elements 103. Two positioning blind holes 407 are symmetrically arranged on the second clamping arm 40 along the width direction. One end of the elastic element 103 is located in the positioning blind hole 407, and the other end abuts against the second clamping arm 40.

[0071] Understandably, the two elastic elements 103 are symmetrically arranged on both sides of the second clamping arm 40, which enables the force generated when the locking member 210 locks to be evenly distributed between the two elastic elements 103, avoiding the first clamping arm 30 from shifting to one side due to uneven force, thus improving overall stability. The design of the positioning blind hole 407 can effectively limit the excessive displacement and deformation of the elastic element 103, increasing the reliability and lifespan of the elastic element 103.

[0072] Please continue to combine Figure 2 and Figure 7The housing 10 includes a detachably connected upper housing 100 and a lower housing 101. A first fixing post 104 and a second fixing post 105 are provided on the inner wall of the lower housing 101. A first clearance groove 408 is provided on the second clamping arm 40 corresponding to the first fixing post 104, and a second clearance groove 409 is provided on the second fixing post 105. The first fixing post 104 passes through the first clearance groove 408 and is rotatably connected to the first transmission gear 201. The second fixing post 105 passes through the second clearance groove 409 and is rotatably connected to the second transmission gear 202.

[0073] Understandably, in this embodiment, the shape of the upper housing 100 and the lower housing 101 and the method of detachable connection are not limited. For example, the upper housing 100 and the lower housing 101 can be detachably connected by screws or by a snap-fit ​​structure.

[0074] Understandably, the design of the first fixed post 104 and the second fixed post 105 ensures that the first transmission gear 201 and the second transmission gear 202 rotate only relative to the first fixed post 104 and the second fixed post 105 during transmission, without displacement. This ensures the stable position of the first transmission gear 201 and the second transmission gear 202 during operation and avoids transmission failure caused by loosening or displacement.

[0075] Understandably, the first clearance groove 408 and the second clearance groove 409 are strip-shaped grooves extending along the opening and closing direction of the second clamping arm 40, and their length should not be less than their maximum opening and closing distance to avoid affecting the opening and closing of the second clamping arm 40. The cooperation between the clearance groove and the fixing post can also guide the second clamping arm 40, further ensuring its opening and closing stability.

[0076] Optionally, the first fixing post 104 and the second fixing post 105 can also be disposed on the inner wall of the upper housing 100, and correspondingly, the first clearance groove 408 and the second clearance groove 409 are disposed on the first clamping arm 30.

[0077] Please see Figure 4 and Figure 7 Furthermore, at least one sliding block 218 is protruding from the top surface of the transmission block 200, and at least one sliding groove 308 is provided on the first clamping arm 30 corresponding to the sliding block 218, with the sliding block 218 extending into the sliding groove 308.

[0078] Understandably, the sliding groove 308 is a strip-shaped groove extending along the opening and closing direction of the first clamping arm 30, and its length should not be less than its maximum opening and closing distance to avoid affecting the opening and closing of the first clamping arm 30. The cooperative design of the sliding block 218 and the sliding groove 308 enables the transmission block 200 to slide smoothly and steadily during operation, ensuring that it always remains in the correct position, avoiding transmission errors or poor gear meshing caused by component misalignment, and thus ensuring the stability of the opening and closing of the first clamping arm 30 and the second clamping arm 40.

[0079] As a specific example, two transmission blocks 200 are symmetrically arranged on the top surface of the transmission block 200. Correspondingly, two sliding grooves 308 are symmetrically arranged on the first clamping arm 30. A boss is provided at the top of the transmission block 200. The boss engages with the side wall of the sliding groove 308, which makes the sliding engagement between the sliding block 218 and the sliding groove 308 more reliable.

[0080] Please see Figure 8 The second embodiment of this utility model provides a bracket 2, including a support structure 50 and the above-mentioned clamping component 1, wherein the clamping component 1 and the support structure 50 are fixedly connected or movably connected.

[0081] Understandably, the bracket 2 in this embodiment includes, but is not limited to, vehicle brackets, desktop brackets, selfie stick brackets, cycling brackets, etc. Furthermore, a charging ring, circuit board, or other structures can be further incorporated into the housing 10 of the clamping component 1 to meet the specific application requirements of the bracket 2.

[0082] Understandably, the bracket 2 in this embodiment also has the same beneficial effects as the clamping component 1 described above, which will not be repeated here.

[0083] Compared with the prior art, the clamping assembly and bracket provided by this utility model have the following beneficial effects:

[0084] 1. The clamping assembly provided in this embodiment of the present invention, in which the first clamping arm, the transmission block, and the second clamping arm are stacked sequentially within the housing, effectively saves space and improves the compactness of the assembly. The first and second racks are symmetrically arranged on both sides of the transmission block. The first transmission gear meshes between the first and third racks, and the second transmission gear meshes between the second and fourth racks. When the transmission block slides along its length, the first clamping arm moves in the opposite direction to the transmission block. Simultaneously, because the transmission block engages with the second clamping arm, it can directly drive the second clamping arm to move, achieving synchronous opening and closing of the first and second clamping arms. This design ensures that the transmission of the first clamping arm is achieved through the combined action of two sets of symmetrical racks and transmission gears, guaranteeing uniform force on both sides of the first clamping arm and reducing errors and uneven friction caused by unilateral transmission. This makes the first clamping arm more stable, smooth, and precise during operation, avoiding deviation or jamming.

[0085] 2. In the clamping assembly provided in this embodiment of the present invention, a first groove is formed on the first clamping arm corresponding to the transmission block, and a second groove is formed on the second clamping arm corresponding to the transmission block. The first and second grooves together form a receiving cavity, and the transmission block is disposed within the receiving cavity. The first and second grooves are used to limit and guide the transmission block, ensuring that the transmission block can only slide along its length direction. This makes the force on the transmission block more uniform, enabling it to move more stably and avoiding jamming.

[0086] 3. The clamping assembly provided in this embodiment of the present invention includes an adjustment knob and a threaded rod. The transmission block has a strip-shaped groove along its length, and a threaded component is embedded within the groove. One end of the threaded rod is placed in the strip-shaped groove and threadedly connected to the threaded component, while the other end extends out of the housing and is connected to the adjustment knob. By rotating the adjustment knob, the threaded rod and the threaded component can be moved relative to each other. The threaded component, embedded in the strip-shaped groove, further drives the entire transmission block and the threaded rod to move relative to each other, achieving synchronous opening and closing of the first and second clamping arms. Through the threaded rotational connection, the degree of opening and closing between the first and second clamping arms can be precisely adjusted, ensuring that the clamping assembly is suitable for electronic products of various sizes. Placing the threaded rod in the strip-shaped groove guides and limits its movement. The threaded rod moves smoothly along the strip-shaped groove, effectively limiting its degree of freedom and preventing unnecessary offset or shaking, further ensuring the stability of the opening and closing of the first and second clamping arms.

[0087] 4. The clamping assembly provided in this embodiment of the present invention includes a locking component in the transmission assembly. The second clamping arm has a slot, through which the transmission block passes through the slot and is rotatably connected to the locking component. A limiting step is provided on the transmission block inside the housing near the slot, the width of which is greater than the width of the slot. The locking component securely locks the transmission block in its current state, preventing accidental loosening or displacement. The design of the limiting step not only allows the second clamping arm to open outwards but also limits the range of motion of the transmission block when locked by the locking component, preventing the transmission block from dislodging or becoming misaligned.

[0088] 5. The clamping assembly provided in this embodiment of the present invention includes an eccentric wheel and a lever. The eccentric wheel has a first through hole, and the end of the transmission block has a second through hole. A rotating shaft is disposed within the first and second through holes. The eccentric wheel and the transmission block are rotatably connected via the rotating shaft. The rotation of the eccentric wheel causes its center position to shift, thereby generating a large torque between the rotating shaft and the transmission block. This allows for precise locking and adjustment of the clamping arm through adjustment of the eccentric wheel. The lever further simplifies operation, allowing for quick unlocking or locking when needed, thus facilitating adjustment and operation.

[0089] 6. The clamping assembly provided in this embodiment of the present invention includes a detachably connected upper housing and a lower housing. A first fixing post and a second fixing post are provided on the inner wall of the lower housing. A first clearance groove and a second clearance groove are provided on the second clamping arm. The first fixing post passes through the first clearance groove and is rotatably connected to the first transmission gear, and the second fixing post passes through the second clearance groove and is rotatably connected to the second transmission gear. The design of the first and second fixing posts ensures that the transmission gear rotates only relative to the fixing posts during transmission, without displacement, thus ensuring the stability of the transmission gear's position during operation and preventing transmission failure due to loosening or displacement of the transmission gear.

[0090] 7. In the clamping assembly provided in this embodiment of the present invention, at least one sliding block is protruding from the top surface of the transmission block, and at least one sliding groove is provided on the first clamping arm corresponding to the sliding block, with the sliding block extending into the sliding groove. The cooperative design of the sliding block and the sliding groove enables the transmission block to slide smoothly and steadily during operation, ensuring that it always remains in the correct position and avoiding transmission errors or poor gear meshing caused by component misalignment.

[0091] 8. In the clamping assembly provided in this embodiment of the present invention, an elastic element is provided between the first clamping arm and the second clamping arm, with both ends of the elastic element abutting against the first clamping arm and the second clamping arm, respectively. When the locking member locks, the force is first applied to the second clamping arm. Because of the elastic deformation of the elastic element, this force is concentrated on the second clamping arm, thereby achieving the locking of the second clamping arm. The first clamping arm, because it abuts against the elastic element, is not directly subjected to the locking force and therefore does not move synchronously, allowing the locking member to achieve more precise locking and maintaining clamping stability.

[0092] 9. In the clamping assembly provided in this embodiment of the present invention, two elastic elements are provided. Two positioning blind holes are symmetrically arranged along the width direction on the second clamping arm. One end of each elastic element is located within a positioning blind hole, and the other end abuts against the second clamping arm. This design allows the force generated when the locking element is engaged to be evenly distributed between the two elastic elements, preventing the first clamping arm from shifting to one side due to uneven force distribution, thus improving overall stability. The design of one end of the elastic element being located within a positioning blind hole and the other end abutting against the second clamping arm effectively limits excessive displacement and deformation of the elastic element, increasing its reliability and lifespan.

[0093] 10. This utility model embodiment also provides a bracket, which has the same beneficial effects as the clamping component described above, and will not be described in detail here.

[0094] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the principles of the present utility model should be included within the protection scope of the present utility model.
