Description

Technical Field

[0001] This invention relates to clamping devices, and more particularly to a clamping mechanism and an electronic device bracket having the same. Background Technology

[0002] With the development of electronic technology, electronic devices such as smartphones and tablets have become indispensable personal items for people's lives, work, and entertainment. To facilitate the use of these devices, people use electronic device stands to support and secure them. An electronic device stand generally includes a clamp, a support component, and a fixing device. The clamp is connected to the bottom of the support component, and the fixing device is connected to the top of the support component. In use, the entire electronic device stand is first secured to the support using the clamp, and then the electronic device is installed on the fixing device.

[0003] In related technologies, the clamping seat, as a clamping component, has poor clamping reliability. Furthermore, whether it is a threaded locking method or a press-locking method, it is difficult to achieve both easy operation and reliable clamping and locking. Summary of the Invention

[0004] This invention aims to at least partially solve one of the technical problems in the related art. Therefore, the object of this invention is to provide a clamping mechanism and an electronic device bracket having the same.

[0005] To achieve the above objectives, in one aspect, the clamping mechanism according to an embodiment of the present invention includes:

[0006] A guide rod having a toothed surface comprising a plurality of toothed grooves spaced apart along the axial direction of the guide rod;

[0007] The first clamping plate is fixed to the guide rod;

[0008] The second clamping plate is slidably disposed on the guide rod, and the second clamping plate and the first clamping plate are arranged opposite to each other in the axial direction of the guide rod.

[0009] A lever locking member having a pivot end and a pressing end, the pivot end being pivotally connected to the second clamping plate and pivotable about an axis perpendicular to the guide rod, the pivot end having a first tooth that engages with the toothed groove; the pressing end being adapted for user operation to drive the pivot end to rotate between an unlocked position and a locked position;

[0010] An elastic self-locking member is disposed on the second clamping plate member, and the elastic self-locking member has a second tooth that mates with the tooth groove;

[0011] The pivot end and the elastic self-locking member form a linkage structure. When the pressing end is pressed, causing the pivot end to rotate from the unlocked position to the locked position, the first tooth and the second tooth are respectively inserted into the tooth groove, and the second clamping plate and the first clamping plate are relatively close to each other and clamped together. When the pivot end rotates from the locked position to the unlocked position, the first tooth exits the tooth groove, and the pivot end, in conjunction with the elastic self-locking member, causes the second tooth to exit the tooth groove.

[0012] In addition, the clamping mechanism according to the above embodiments of the present invention may also have the following additional technical features:

[0013] According to one embodiment of the present invention, one of the pivot end and the resilient self-locking member has an actuating groove, and the other of the pivot end and the resilient self-locking member has a pressure-receiving boss extending into the actuating groove;

[0014] When the pivot end rotates from the locked position to the unlocked position, the actuating groove drives the pressure boss, and the elastic self-locking member moves away from the tooth surface, so that the second tooth exits the tooth groove.

[0015] According to one embodiment of the present invention, the lever locking member includes:

[0016] An unlocking lever, wherein the first end of the unlocking lever serves as the pressing end, and the second end of the unlocking lever is pivotally connected to the second clamping plate and is pivotable about the axis;

[0017] A locking wheel is provided at the second end of the unlocking lever and is rotatable about the axis relative to the unlocking lever. One of the locking wheel and the second end is provided with a delay groove, and the other of the locking wheel and the second end is provided with a toggle part, which is located in the delay groove.

[0018] The actuating groove is located at the second end, the first tooth is located on the surface of the locking wheel, and the width of the delay groove is greater than the width of the actuating part, so that when the second end rotates from the locked position to the unlocked position, the second tooth exits the groove first, and the first tooth exits the groove later.

[0019] According to one embodiment of the present invention, there is an intermediate position between the locking position and the unlocking position, and when the second end is located in the intermediate position, the toggle part abuts against one side wall of the delay groove;

[0020] When the second end rotates from the locked position to the intermediate position, the actuating groove drives the pressure boss to at least partially disengage the second tooth from the tooth groove; when the second end rotates from the intermediate position to the unlocked position, the actuating part drives the locking wheel to rotate to disengage the first tooth from the tooth groove.

[0021] According to one embodiment of the present invention, the second clamping member includes:

[0022] plywood;

[0023] A sliding sleeve is fixed to one side of the clamping plate and slidably sleeved on the guide rod. The side wall of the sliding sleeve opposite to the tooth surface is provided with an opening, and the first tooth and the second tooth are inserted into the corresponding tooth groove through the opening.

[0024] According to one embodiment of the present invention, the second end is provided with two opposing pivot portions, and the locking wheel is located between the two pivot portions;

[0025] The second clamping plate is provided with a pivot shaft, which passes through the two pivoting parts and the locking wheel, so that the pivoting parts can pivot between the second clamping plate and the locking wheel and the pivoting parts.

[0026] According to one embodiment of the present invention, the connection between the sliding sleeve and the clamping plate has two opposing stiffeners, the second end is located between the two stiffeners, and one end of the pivot shaft passes through one of the two stiffeners, and the other end of the pivot shaft passes through the other of the two stiffeners.

[0027] According to one embodiment of the present invention, the width of the actuating groove is slightly larger than the width of the pressure boss.

[0028] According to one embodiment of the present invention, the elastic self-locking member is an elastic plastic member that is integrally formed with the second clamping plate member.

[0029] According to one embodiment of the present invention, a mounting groove is provided on the side of the clamp plate adjacent to the sliding sleeve, and the elastic self-locking member is installed in the mounting groove and can slide elastically in a predetermined direction, the predetermined direction being perpendicular to the axis and the guide rod.

[0030] According to one embodiment of the present invention, the end of the elastic self-locking member away from the sliding sleeve has an elastic structure, and the elastic structure abuts against the side wall of the mounting groove;

[0031] The elastic structure is an elastic plastic part integrally formed with the elastic self-locking component;

[0032] Alternatively, the elastic structure may be an independently installed metal elastic element.

[0033] According to one embodiment of the present invention, the elastic self-locking member has a supporting surface that is close to or in contact with the wheel surface of the locking wheel.

[0034] According to one embodiment of the present invention, a backstop structure is provided between the lever locking member and the elastic self-locking member to prevent the elastic self-locking member from retracting away from the tooth surface after the second tooth is inserted into the tooth groove.

[0035] On the other hand, the electronic device bracket according to an embodiment of the present invention includes:

[0036] The clamping mechanism as described above;

[0037] A fastener is mounted on the guide rod to secure electronic equipment.

[0038] The clamping mechanism and electronic device bracket having it provided according to embodiments of the present invention have a lever locking member and an elastic self-locking member. The pivot end of the elastic self-locking member and the lever locking member form a linkage structure. When the pressing end of the lever locking member is pressed, the first tooth of the pivot end can be inserted into the tooth groove on the tooth surface of the guide rod. At the same time, under the elastic action, the second tooth of the elastic self-locking member can be inserted into the tooth groove on the tooth surface of the guide rod. The second clamping plate and the first clamping plate are relatively close and clamped together. In this way, it can be quickly locked by pressing. The double locking action of the elastic self-locking member and the lever locking member ensures the locking reliability of the second clamping plate. In addition, when unlocking, it is only necessary to rotate the pressing end upward, and the first tooth of the pivot end can be disengaged from the tooth groove. At the same time, the linkage function of the elastic self-locking member causes the second tooth to also disengage from the tooth groove, making the operation extremely convenient. Thus, while ensuring the locking reliability, it also achieves operational convenience.

[0039] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

"Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0080] The clamping mechanism and the electronic device bracket having the same are described in detail below with reference to the accompanying drawings.

[0081] Reference Figures 1 to 8 As shown, the clamping mechanism provided according to an embodiment of the present invention includes a guide rod 10, a first clamping plate 20, a second clamping plate 30, a lever locking member 40, and an elastic self-locking member 50.

[0082] Specifically, the guide rod 10 has a toothed surface, the toothed surface comprising a plurality of toothed grooves H10 spaced apart along the axial direction of the guide rod 10. Figure 1 In the example, the guide rod 10 extends in the vertical direction and is generally a quadrangular prism structure, with the toothed surface located on one side of the guide rod 10.

[0083] The first clamping plate 20 is fixed to the guide rod 10. Preferably, the lower end of the guide rod 10 and the first clamping plate 20 are integrally formed, thus ensuring a reliable connection between the first clamping plate 20 and the guide rod 10.

[0084] The second clamping plate 30 is slidably disposed on the guide rod 10, and the second clamping plate 30 and the first clamping plate 30 are arranged opposite each other in the axial direction of the guide rod 10. That is, the first clamping plate 20 and the second clamping plate 30 are arranged opposite each other and define the clamping gap. By sliding the second clamping plate 30 along the guide rod 10, the clamping gap between the second clamping plate 30 and the first clamping plate 20 can be adjusted, thereby making it easier to accommodate objects of various thicknesses during use.

[0085] The lever locking member 40 has a pivot end and a pressing end. The pivot end is pivotally connected to the second clamping plate member 30 and pivotable about an axis perpendicular to the guide rod 10. The pivot end has a first tooth 4021 that mates with the toothed groove H10. The pressing end is adapted for user operation to drive the pivot end to rotate between an unlocked position and a locked position. Figure 1 In the example, the axis extends horizontally.

[0086] In other words, the lever locking member 40 is pivotally connected to the second clamping plate member 30 via a pivot end. This lever locking member 40 can rotate about an axis perpendicular to the guide rod 10. Specifically, during operation, the lever locking member 40 can be rotated by pressing clockwise with the pressing end or by pulling counterclockwise upwards. Correspondingly, the pivot end can rotate between the unlocked and locked positions. Furthermore, the pivot end has a first tooth 4021. When the pivot end rotates between the unlocked and locked positions, the first tooth 4021 can insert into or retract from the toothed groove H10 on the guide rod 10.

[0087] An elastic self-locking member 50 is disposed on the second clamping plate member 30, and the elastic self-locking member 50 has a second tooth 501 that mates with the tooth groove H10. Preferably, the elastic self-locking member 50 is located below the lever locking member 40, and the second tooth 501 is located below the first tooth 4021. The pivot end forms a linkage structure with the elastic self-locking member 50.

[0088] When the pressing end is pressed, causing the pivot end to rotate from the unlocked position to the locked position, the first tooth 4021 and the second tooth 501 are respectively inserted into the tooth groove H10, and the second clamping plate 30 and the first clamping plate 20 are brought close together and clamped. When the pivot end rotates from the locked position to the unlocked position, the first tooth 4021 exits the tooth groove H10, and the pivot end, in conjunction with the elastic self-locking member 50, causes the second tooth 501 to exit the tooth groove H10.

[0089] In other words, the elastic self-locking member 50 has a second tooth 501 that can be inserted into or withdrawn from the toothed groove H10 on the guide rod 10. By utilizing the engagement of the second tooth 501 on the elastic self-locking member 50 with the toothed groove H10 on the guide rod 10, and the engagement of the first tooth 4021 on the pivot end of the lever locking member 40 with the toothed groove H10 on the guide rod 10, reliable locking between the second clamping plate 30 and the guide rod 10 can be ensured. Furthermore, since a linkage structure is formed between the elastic self-locking member 50 and the pivot end of the lever locking member 40, when the pivot end rotates, it can move the elastic self-locking member 50 closer to or further away from the toothed surface, thereby enabling the second tooth 501 to be inserted into or withdrawn from the toothed groove H10 on the guide rod 10.

[0090] In practical use, first slide the second clamping plate 30 up and down to a suitable position to ensure that the clamping gap between the first clamping plate 20 and the second clamping plate 30 is just right to match the object being clamped. Then, press down on the pressing end of the lever locking member 40, so that the pivot end of the lever locking member 40 rotates from the unlocked position to the locked position. During this process, the first tooth 4021 on the pivot end inserts into the tooth groove H10 on the guide rod 10. At the same time, the pivot end can be linked with the elastic self-locking member 50, and the elastic self-locking member 50 can, through its own elasticity, make it... The second tooth 501 on the guide rod 10 is inserted into the other tooth grooves H10 on the guide rod 10. As the pressing end is pressed, the first tooth 4021 cooperates with the tooth grooves H10, and the lever action forces the guide rod 10 to move upward. Then the first clamping plate 20 moves upward and the second clamping plate 30 moves downward. The second clamping plate 30 and the first clamping plate 20 can then come closer to each other and clamp the object being clamped. In this way, by using the first tooth 4021 and the second tooth 501 to cooperate with the tooth grooves H10 on the guide rod 10 respectively, the second clamping plate 30 is locked and fixed.

[0091] When unlocking is required, simply pull the pressing end of the lever self-locking member upwards, causing the pivot end of the lever locking member 40 to rotate from the locked position to the unlocked position. During this process, the first tooth 4021 on the pivot end disengages from the tooth groove H10 on the guide rod 10. At the same time, the pivot end can be linked with the elastic self-locking member 50, which moves away from the tooth surface, causing the second tooth 501 on it to disengage from the tooth groove H10 on the guide rod 10. In this way, the locking state of the lever locking member 40 and the elastic self-locking member 50 can be released in a coordinated manner.

[0092] The clamping mechanism provided in this embodiment of the invention includes a lever locking member 40 and an elastic self-locking member 50. The elastic self-locking member 50 and the pivot end of the lever locking member 40 form a linkage structure. When the pressing end of the lever locking member 40 is pressed, the first tooth 4021 of the pivot end can be inserted into the tooth groove H10 on the tooth surface of the guide rod 10. At the same time, under the elastic action, the second tooth 501 of the elastic self-locking member 50 can be inserted into the tooth groove H10 on the tooth surface of the guide rod 10. Thus, the double locking action of the elastic self-locking member 50 and the lever locking member 40 ensures the locking reliability of the second clamping plate 30. In addition, when unlocking, it is only necessary to rotate the pressing end upward, and the first tooth 4021 of the pivot end can be disengaged from the tooth groove H10. At the same time, the linkage function of the elastic self-locking member 50 causes the second tooth 501 to also disengage from the tooth groove H10, making the operation extremely convenient. Thus, while ensuring the locking reliability, operational convenience is also achieved.

[0093] Reference Figures 3 to 8As shown, in some embodiments of the present invention, one of the pivot end and the resilient self-locking member 50 has an actuating groove H40, and the other of the pivot end and the resilient self-locking member 50 has a pressure-receiving boss 502 extending into the actuating groove H40. Exemplarily, the actuating groove H40 is provided on the circumferential surface of the pivot end, and the pressure-receiving boss 502 is provided on the resilient self-locking member 50 and protrudes upward.

[0094] When the pivot end rotates from the locked position to the unlocked position, the actuating groove H40 drives the pressure boss 502, and the elastic self-locking member 50 moves away from the tooth surface, so that the second tooth 501 exits the tooth groove H10.

[0095] In other words, in this embodiment, the pivot end and the elastic self-locking member 50 are linked by the cooperation of the actuating groove H40 and the pressure-receiving boss 502. The pressure-receiving boss 502 on the elastic self-locking member 50 extends into the actuating groove H40 on the pivot end. When the pivot end rotates, the actuating groove H40 rotates accordingly, and the actuating groove H40 can push the pressure-receiving boss 502, so that the pressure-receiving boss 502 and the elastic self-locking member 50 move towards or away from the tooth surface of the guide rod 10, thereby realizing the linkage between the pivot end and the elastic self-locking member 50. Moreover, the rotational motion of the pivot end can be converted into the linear motion of the elastic self-locking member 50. This linkage structure is simple in structure, reliable in linkage, and convenient in assembly.

[0096] It is understood that in other embodiments of the present invention, the linkage structure between the pivot end and the elastic self-locking member 50 can also be implemented in other ways. For example, the pivot end and the elastic self-locking member 50 can be pivotally connected by an eccentric shaft, and the eccentric shaft can be eccentrically connected to the pivot end. In this way, the linkage between the pivot end and the elastic self-locking member 50 can also be realized.

[0097] Reference Figures 1 to 8 As shown, in some embodiments of the present invention, the lever locking member 40 includes an unlocking lever 401 and a locking wheel 402. The first end D4a of the unlocking lever 401 serves as the pressing end, and the second end D4b of the unlocking lever 401 is pivotally connected to the second clamping plate member 30 and is pivotable about the axis. When the first end D4a of the unlocking lever 401 is operated, the unlocking lever 401 can be driven to rotate, and the second end D4b of the unlocking lever 401 can rotate about the axis between the unlocked position and the locked position.

[0098] A locking wheel 402 is disposed at the second end D4b of the unlocking lever 401 and is rotatable about the axis relative to the unlocking lever 401. One of the locking wheel 402 and the second end D4b has a delay groove H41, and the other of the locking wheel 402 and the second end D4b has a toggle part 4012 located within the delay groove H41. Figure 3and Figures 5 to 8 In the example, the delay groove H41 is provided on the locking wheel 402, and the actuating part 4012 is provided on the second end D4b of the unlocking lever 401. That is to say, on the one hand, the unlocking lever 401 can rotate about its axis relative to the second clamping plate 30, and on the other hand, the locking wheel 402 can rotate about its axis relative to the unlocking lever 401. In other words, when the unlocking lever 401 rotates, the locking wheel 402 does not rotate synchronously.

[0099] A toggle groove H40 is provided on the second end D4b, and the first tooth 4021 is provided on the wheel surface of the locking wheel 402. The width of the delay groove H41 is greater than the width of the toggle part 4012, so that when the second end D4b rotates from the locked position to the unlocked position, the second tooth 501 first exits the tooth groove H10, and the first tooth 4021 then exits the tooth groove H10.

[0100] Preferably, there is an intermediate position between the locked position and the unlocked position. When the second end D4b is in the intermediate position, the toggle part 4012 abuts against one side wall of the delay groove H41. That is, the width of the delay groove H41 defines the intermediate position of the rotation of the second end D4b.

[0101] When the second end D4b rotates from the locked position to the intermediate position, the actuating groove H40 drives the pressure boss 502, causing the second tooth 501 to at least partially exit the tooth groove H10; when the second end D4b rotates from the intermediate position to the unlocked position, the actuating part 4012 drives the locking wheel 402 to rotate, causing the first tooth 4021 to exit the tooth groove H10. That is, during the process of the second end D4b rotating from the locked position to the intermediate position, the second tooth 501 first exits or partially exits the tooth groove H10, and during the process of the second end D4b rotating from the intermediate position to the unlocked position, the first tooth 4021 then exits the tooth groove H10.

[0102] In other words, the width of the delay groove H41 is configured to be greater than the width of the actuating part 4012, so that the actuating part 4012 can rotate a certain angle within the delay groove H41. When the second end D4b rotates from the locked position to the unlocked position, the second end D4b first rotates a certain angle to reach the middle position, and the actuating part 4012 of the second end D4b rotates in the delay groove H41 on the locking wheel 402. Within this angle range, the second end D4b rotates, while the locking wheel 402 remains stationary. That is, during the process of the second end D4b rotating from the locked position to the middle position, the second end D4b rotates, while the locking wheel 402 remains stationary. As the second end D4b continues to rotate, the actuating part 4012 of the second end D4b abuts against the side wall of the delay groove, pushing the locking wheel 402 to rotate synchronously. That is, during the process of the second end D4b rotating from the middle position to the unlocked position, the locking wheel 402 rotates synchronously when the second end D4b rotates. Thus, during the process of the second end D4b rotating from the locked position to the unlocked position, the locking wheel 402 does not rotate at first, and then rotates synchronously when the second end D4b rotates to the middle position at a certain angle. This angle is limited by the rotation range of the actuating part 4012 in the delay groove H41.

[0103] The specific unlocking process is as follows: Pull the pressing end of the lever self-locking component upwards, causing the second end D4b of the unlocking lever 401 to rotate from the locked position to the unlocked position. During this process, the second end D4b first rotates to the middle position at a certain angle, and the actuating part 4012 rotates within the delay groove H41. The locking wheel 402 remains stationary. When rotating within this angle, the actuating groove H40 on the second end D4b drives the pressure boss 502, forcing the elastic self-locking component 50 to move away from the tooth surface of the guide rod 10, thereby causing the second tooth 501 to first disengage or partially disengage from the tooth groove H10. Since the locking wheel 402 remains stationary, correspondingly, the first tooth 4021 on the locking wheel 402 remains stationary, that is, the first tooth 4021 still engages with the tooth groove H10. Next, the second end D4b continues to rotate from the middle position to the unlocked position. The actuating part 4012 of the second end D4b abuts against the side wall of the delay groove, pushing the locking wheel 402 to rotate synchronously. During this process, on the one hand, the elastic self-locking member 50 continues to move away from the tooth surface, and the second tooth 501 moves further away from the tooth groove H10. On the other hand, the locking wheel 402 rotates, causing the first tooth 4021 to exit the tooth groove H10 on the guide rod 10. In this way, the locking state of the lever locking member 40 and the elastic self-locking member 50 can be released in a coordinated manner.

[0104] In this embodiment, the lever locking member 40 with the above-described structure is used. The locking wheel 402 and the unlocking lever 401 rotate asynchronously, thereby unlocking the second tooth 501 on the elastic self-locking member 50 first, and then unlocking the first tooth 4021 on the locking wheel 402. This sequential unlocking method significantly improves the reliability of unlocking. At the same time, it is not easy for mechanical interference and other problems to occur in the structure.

[0105] Reference Figures 1 to 2 as well as Figures 4 to 5 As shown, in one embodiment of the present invention, the second clamping plate 30 includes a clamping plate 301 and a sliding sleeve 302. The sliding sleeve 302 is fixed to one side of the clamping plate 301 and slidably sleeved on the guide rod 10. Preferably, the sliding sleeve 302 and the clamping plate 301 are integrally formed. An opening H30 is provided on the side wall of the sliding sleeve 302 opposite to the tooth surface. The first tooth 4021 and the second tooth 501 are inserted into the corresponding tooth groove H10 through the opening H30.

[0106] In this embodiment, the second clamping plate 30 is mainly composed of a clamping plate 301 and a sliding sleeve 302. By utilizing the sliding sleeve 302 to slide in cooperation with the guide rod 10, it can be ensured that the clamping plate 301 slides reliably along the guide rod 10, thereby making the adjustment of the clamping gap between the first clamping plate 20 and the second clamping plate 30 more convenient and reliable.

[0107] Reference Figures 4 to 5 As shown, in one embodiment of the present invention, the second end D4b is provided with two opposing pivot portions 4011, and the locking wheel 402 is located between the two pivot portions 4011.

[0108] The second clamping plate 30 is provided with a pivot shaft, which passes through the two pivoting parts 4011 and the locking wheel 402, so that the pivoting parts 4011 and the second clamping plate 30, and the locking wheel 402 and the pivoting parts 4011 can pivot.

[0109] In this embodiment, the locking wheel 402 is positioned between the two pivoting parts 4011 and pivotally connected to the second clamping plate 30 via a pivoting shaft. This allows the second end D4b to pivot relative to the second clamping plate 30, and the locking wheel 402 to pivot relative to the second end D4b. Furthermore, this assembly structure makes the assembly relationship between the locking wheel 402 and the second end D4b more stable and reliable, thus improving the reliability of unlocking and locking operations.

[0110] Preferably, the connection between the sliding sleeve 302 and the clamping plate 301 has two opposing stiffening plates 303, the second end D4b is located between the two stiffening plates 303, and one end of the pivot shaft passes through one of the two stiffening plates 303, while the other end of the pivot shaft passes through the other of the two stiffening plates 303. In this way, the stiffening plates 303 between the sliding sleeve 302 and the clamping plate 301 can not only strengthen the connection between the sliding sleeve 302 and the clamping plate 301, but also facilitate the pivot connection of the second end D4b of the unlocking lever 401 between the two stiffening plates 303, ensuring a more reliable pivot connection.

[0111] Reference Figure 3 As shown, in some embodiments of the present invention, the width of the actuating groove H40 is slightly larger than the width of the pressure boss 502. Thus, the pressure boss 502 can rotate relative to the actuating groove H40 by a certain angle. Correspondingly, the unlocking lever 401 can rotate relative to the elastic self-locking member 50 by a certain angle (e.g., 5°).

[0112] In this embodiment, the width of the actuating groove H40 is slightly larger than the width of the pressure-bearing boss 502, which has two effects. First, since the pressure-bearing boss 502 can move a certain distance relative to the actuating groove H40, it can be ensured that in the locked state, the elastic self-locking member 50 can move the tooth surface of the guide rod 10 under the elastic action, ensuring that the second tooth 501 can elastically abut against the tooth groove H10 of the tooth surface, achieving an effective and reliable elastic self-locking effect. Second, when the pressing end of the unlocking lever 401 is accidentally activated, the unlocking lever 401 can be allowed to have a fault tolerance angle. That is, when the rotation angle of the unlocking lever 401 is less than the fault tolerance angle, the actuating groove H40 will not drive the pressure-bearing boss 502. In this way, the unlocking lever 401 can be prevented from being accidentally activated and unlocked.

[0113] It is understandable that the elastic self-locking component 50 can be made into an independent part or into an integral structural component with the second clamping plate component 30.

[0114] In one example, the elastic self-locking member 50 is an elastic plastic part that forms an integral structure with the second clamping plate member 30. The elastic plastic part can be injection molded with the second clamping plate member 30 in one step using an injection molding process, and its own elasticity ensures that the second tooth 501 can elastically engage with the tooth groove H10.

[0115] In another embodiment, the elastic self-locking member 50 can be a separate component. Correspondingly, for ease of installation, a mounting groove H31 is provided on the side of the clamp plate adjacent to the sliding sleeve 302. The elastic self-locking member 50 is installed in the mounting groove H31 and can slide elastically in a predetermined direction, which is perpendicular to both the axis and the guide rod 10. This separate component can provide a relatively more precise and suitable elastic force, and is easy to assemble.

[0116] It should be noted that when the elastic self-locking member 50 is designed as an independent component, the end of the elastic self-locking member 50 away from the sliding sleeve 302 has an elastic structure 503. The elastic structure 503 abuts against the side wall of the mounting groove H31. Thus, when the elastic self-locking member 50 moves away from the tooth surface in the predetermined direction, the elastic structure 503 can be compressed. The elastic structure 503 can provide an elastic force toward the tooth surface.

[0117] Furthermore, the elastic structure 503 can be an elastic plastic part integrally formed with the elastic self-locking member 50, for example... Figures 4 to 5 In this example, the elastic plastic part is formed in a serpentine shape, which provides a relatively reliable elastic force. In other examples, the elastic structure 503 can be a separately mounted metal elastic element, such as a spring, with one end abutting against the elastic self-locking element 50 and the other end abutting against the side wall of the groove. Using a metal elastic element can provide a reliable elastic force and has a long service life.

[0118] In one example of the present invention, the elastic self-locking member 50 has a supporting surface S50, which is close to or in contact with the wheel surface of the locking wheel 402. Thus, during the pressing of the unlocking lever 401, the wheel surface of the locking wheel 402 is supported by the supporting surface S50, and there is a relative force between the two. This ensures that when the unlocking lever 401 is rotated to the locking position, it is not easy to reverse or back, and the overall structural strength is also higher.

[0119] In one embodiment of the present invention, a backstop structure is provided between the lever locking member 40 and the elastic self-locking member 50 to prevent the elastic self-locking member 50 from retracting away from the tooth surface after the second tooth 501 is inserted into the tooth groove H10. Thus, in the locked state, the backstop structure prevents the elastic self-locking member 50 from retracting, ensuring that the second tooth 501 and the tooth groove H10 remain in a mating state, thereby further improving the reliability of locking.

[0120] For example, to simplify the structure, the anti-reverse structure may include a side wall S40 of the actuating groove H40 opposite to the side of the pressure boss 502. The side wall S40 of the actuating groove H40 stops the side of the pressure boss 502 to prevent the elastic self-locking member 50 from moving away from the tooth surface. This structure is simple and can also play an anti-reverse role.

[0121] Understandably, in order to further improve the anti-reverse effect, an anti-reverse structure can also be set on the unlocking lever 401 to prevent the elastic self-locking part 50 from retracting.

[0122] According to an embodiment of the present invention, an electronic device bracket includes a fixing member and a clamping mechanism as described above. The fixing member is mounted on the guide rod 10 for fixing the electronic device.

[0123] The electronic device bracket provided according to the embodiments of the present invention has the above-mentioned clamping mechanism, thus ensuring high locking reliability and achieving operational convenience while ensuring locking reliability.
