Description

Technical Field

[0001] This application relates to the field of electronic device accessories technology, and in particular to a clamping bracket. Background Technology

[0002] In related technologies, clamping brackets are commonly used to hold and fix electronic devices to increase the application scenarios of electronic devices. However, the movable arm of the clamping bracket is prone to wobbling, which affects the user experience. Utility Model Content

[0003] In view of this, the present application aims to provide a clamping bracket to solve the problem that the movable arm of the clamping bracket is prone to wobbling.

[0004] To achieve the above objectives, embodiments of this application provide a clamping bracket, comprising:

[0005] The housing is provided with a first contact portion;

[0006] At least one movable arm, the movable arm including a sliding part and a clamping part, the sliding part being connected to the clamping part, the sliding part being slidably disposed within the housing, the movable arm having a clamping state and an idle state along the sliding direction of the sliding part, the sliding part being provided with a second contact part, in the idle state, the second contact part abutting against the first contact part, in the clamping state, the second contact part avoiding the first contact part.

[0007] In some embodiments, the sliding portion is formed with a clearance groove extending along a first direction, one end of the second contact portion is disposed on the groove wall of the clearance groove, and the other end of the second contact portion extends freely, wherein the first direction intersects with the sliding direction of the sliding portion.

[0008] In some embodiments, the extending direction of the second contact portion is the same as the sliding direction of the sliding portion.

[0009] In some embodiments, the second contact portion includes a free segment and a connecting segment, the connecting segment connecting the free segment between the free segment and the groove wall of the clearance groove, the free segment protruding from the clearance groove along the first direction toward the first contact portion.

[0010] In some embodiments, a groove is formed on the side of the second contact portion opposite to the first contact portion.

[0011] In some embodiments, the free segment includes a guide unit and an abutment unit, the guide unit being smoothly connected between the abutment unit and the connecting segment.

[0012] In some embodiments, the housing has a telescopic cavity and an extension communicating with the telescopic cavity, the sliding part can extend out of the telescopic cavity or retract into the telescopic cavity through the extension, and the first contact part is disposed in the telescopic cavity and located at the edge of the extension.

[0013] In some embodiments, in the idle state, the movable arm slides along the sliding direction of the sliding portion to the maximum stroke position, and the second contact portion abuts against the first contact portion. In the clamping state, the movable arm slides along the sliding direction of the sliding portion to the minimum stroke position or any position between the maximum stroke position and the minimum stroke position, and the second contact portion avoids the first contact portion.

[0014] In some embodiments, in the idle state, the movable arm slides along the sliding direction of the sliding portion to the minimum stroke position, and the second contact portion abuts against the first contact portion. In the clamping state, the movable arm slides along the sliding direction of the sliding portion to the maximum stroke position or any position between the maximum stroke position and the minimum stroke position, and the second contact portion avoids the first contact portion.

[0015] In some embodiments, at least a portion of the inner wall of the housing extends toward the second contact portion along the first direction to form the first contact portion.

[0016] In some embodiments, the second contact portion is integrally formed with the sliding portion.

[0017] The clamping bracket provided in this application embodiment has a first contact portion and a second contact portion respectively provided on the housing and the movable arm. In the unloaded state, the second contact portion abuts against the first contact portion. At this time, when the movable arm slides to the minimum or maximum stroke position, one of the first and second contact portions undergoes elastic deformation, or both undergo elastic deformation simultaneously. A contact force perpendicular to the sliding direction is generated between the second and first contact portions, resulting in increased friction between them. This improves the stability of the movable arm when no electronic device is clamped, reduces the likelihood of the movable arm wobbling relative to the housing when no electronic device is clamped, and decreases the probability of abnormal noise during wobbling, thus improving the user experience. In addition, in the clamping state, the second contact portion avoids the first contact portion, which reduces the stroke of the first and second contact portions abutting against each other, increases the durability of the first and second contact portions, and also facilitates the extension and sliding of the movable arm.

Detailed Implementation

[0029] The embodiments of this application will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this application, but should not be used to limit the scope of this application.

[0030] In the description of the embodiments of this application, it should be noted that the terms "upper," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the embodiments of this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0031] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "connection" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application based on the specific circumstances.

[0032] In related technologies, clamping brackets are commonly used to hold and fix electronic devices to increase the application scenarios of electronic devices. However, the movable arm of the clamping bracket is prone to shaking. For example, when in a vehicle, it is easily affected by vehicle bumps, causing the clamping bracket to shake, resulting in the movable arm shaking relative to the housing, which in turn produces abnormal noise and affects the user experience.

[0033] Based on the above, this application provides a clamping bracket 10. Please refer to [link / reference]. Figures 1 to 9 The clamping bracket 10 includes a housing 11 and at least one movable arm 12. The housing 11 has a first contact portion 11a. The movable arm 12 includes a sliding portion 121 and a clamping portion 122. The sliding portion 121 is connected to the clamping portion 122. The sliding portion 121 is slidably disposed within the housing 11. The movable arm 12 has a clamping state and an idle state along the sliding direction of the sliding portion 121. The sliding portion 121 has a second contact portion 1211. In the idle state, the second contact portion 1211 abuts against the first contact portion 11a. In the clamping state, the second contact portion 1211 avoids the first contact portion 11a.

[0034] The clamping bracket 10 in this application can be a gravity bracket, a single-sided magnetic bracket, a wireless charging bracket, etc., and there is no limitation here.

[0035] Furthermore, the clamping bracket 10 in this application can be applied to any means of transportation, such as vehicles, bicycles, and two-wheeled electric vehicles. The application scenarios of the clamping bracket 10 in this application are not limited to these.

[0036] The clamping bracket 10 may also include a fixing arm, and the number of fixing arms is unlimited.

[0037] For example, the clamping bracket 10 includes a housing 11 and a movable arm 12, as well as a fixed arm, which is fixed relative to the housing 11, and the movable arm 12 is telescopically slidable relative to the housing 11. A clamping space is defined between the fixed arm and the movable arm 12 to clamp and fix an electronic device.

[0038] The electronic device mentioned in this application can be a mobile phone, tablet computer, etc., and there are no restrictions.

[0039] The number of movable arms 12 is unlimited; it can be one, two, three, four, or five, etc.

[0040] The housing 11 is provided with a first contact portion 11a, wherein the first contact portion 11a can be provided in the housing 11, the housing 11, or other locations, and there is no limitation on this.

[0041] The clamping portion 122 of the movable arm 12 is used to contact the electronic device and can apply a unidirectional force to the electronic device. At least two clamping portions 122 clamp each other to fix the electronic device. One clamping portion 122 belongs to the movable arm 12, and the other clamping portion 122 may belong to another movable arm 12 or a fixed arm.

[0042] The sliding portion 121 of the movable arm 12 is used to form a sliding engagement with the housing 11. For example, along the sliding direction, one end of the sliding portion 121 is slidably engaged with the housing 11, and the other end is connected to the clamping portion 122.

[0043] The second contact portion 1211 can be provided in the portion of the sliding portion 121 located inside the housing 11, or it can be provided in the portion of the sliding portion 121 located outside the housing 11, and there is no limitation on this.

[0044] The movable arm 12 has a clamping state and an idle state along the sliding direction of the sliding part 121. Here, the clamping state refers to the state in which the movable arm 12 clamps the electronic device, and the idle state refers to the state in which the movable arm 12 does not clamp the electronic device, which can be the natural state of the clamping bracket 10. It is understandable that when the clamping bracket 10 is not clamping any electronic device, the movable arm 12 is easily affected by the bumps during the movement of the vehicle, which makes the movable arm 12 prone to shaking relative to the housing 11, thereby producing abnormal noise.

[0045] It should be noted that, along the sliding direction of the sliding part 121, the movable arm 12 has a maximum stroke position extending out of the housing 11, and a minimum stroke position retracting into the housing 11 along the sliding direction.

[0046] Because the sliding positions of the movable arm 12 of the gravity support and the non-gravity support differ in the unloaded state, for example, the movable arm 12 of the gravity support is usually extended to its maximum stroke position in the unloaded state, while the movable arm 12 of the non-gravity support is usually retracted to its minimum stroke position in the unloaded state. Therefore, the unloaded state of the clamping bracket 10 can be either the movable arm 12 sliding to its minimum stroke position or its maximum stroke position, without any limitation.

[0047] Accordingly, the clamping state of the clamping bracket 10 can be any position where the movable arm 12 slides to the maximum stroke position, the minimum stroke position, or any position between the maximum stroke position and the minimum stroke position, without any restrictions.

[0048] In the idle state, the second contact portion 1211 abuts against the first contact portion 11a. At this time, the movable arm 12 slides to the minimum stroke position or the maximum stroke position. One of the first contact portion 11a and the second contact portion 1211 undergoes elastic deformation, or both undergo elastic deformation simultaneously. A contact force perpendicular to the sliding direction is generated between the second contact portion 1211 and the first contact portion 11a, which increases the friction between the second contact portion 1211 and the first contact portion 11a. This can improve the stability of the movable arm 12 when no electronic device is clamped, improve the situation where the movable arm 12 is prone to shaking relative to the housing 11 when no electronic device is clamped, and reduce the probability of abnormal noise during shaking.

[0049] In the clamping state, the second contact portion 1211 avoids the first contact portion 11a. At this time, the movable arm 12 slides to the maximum stroke position, the minimum stroke position, or any position between the maximum stroke position and the minimum stroke position, and the second contact portion 1211 and the first contact portion 11a do not come into contact. This reduces the stroke during which the first contact portion 11a and the second contact portion 1211 abut, increases the durability of the first contact portion 11a and the second contact portion 1211, and also facilitates the extension and retraction of the movable arm 12.

[0050] For example, during the transition from the clamping state to the idle state, and during the transition from the idle state to the clamping state, the second contact portion 1211 avoids the first contact portion 11a. That is, the second contact portion 1211 only comes into contact with the first contact portion 11a in the idle state, so that the movable arm 12 will not experience frictional resistance from the first contact portion 11a during the extension to the maximum stroke position and retraction to the minimum stroke position, which further facilitates the extension and retraction of the movable arm 12.

[0051] The clamping bracket 10 provided in this application embodiment provides a first contact portion 11a and a second contact portion 1211 on the housing 11 and the movable arm 12, respectively. In the unattended state, the second contact portion 1211 abuts against the first contact portion 11a. At this time, the movable arm 12 slides to the minimum stroke position or the maximum stroke position. One of the first contact portion 11a and the second contact portion 1211 undergoes elastic deformation, or both undergo elastic deformation simultaneously. An abutting force perpendicular to the sliding direction is generated between the second contact portion 1211 and the first contact portion 11a, which increases the friction between the second contact portion 1211 and the first contact portion 11a. This can improve the stability of the movable arm 12 when no electronic device is clamped, improve the situation where the movable arm 12 is prone to shaking relative to the housing 11 when no electronic device is clamped, reduce the probability of abnormal noise during shaking, and improve the user experience of the product. Furthermore, in the clamping state, the second contact portion 1211 avoids the first contact portion 11a, which can reduce the travel of the first contact portion 11a and the second contact portion 1211 abutting each other, increase the durability of the first contact portion 11a and the second contact portion 1211, and also facilitate the extension and retraction of the movable arm 12.

[0052] For example, the housing 11 is a plastic part or a plastic component.

[0053] In some embodiments, please refer to Figures 3 to 5 , Figures 8 to 9 The sliding portion 121 has a clearance groove 121a extending along a first direction. One end of the second contact portion 1211 is disposed on the groove wall of the clearance groove 121a, and the other end of the second contact portion 1211 extends freely. The first direction intersects with the sliding direction of the sliding portion 121.

[0054] By setting one end of the second contact portion 1211 on the groove wall of the clearance groove 121a and allowing the other end of the second contact portion 1211 to extend freely, the second contact portion 1211 is equivalent to a cantilever. The free extension end of the second contact portion 1211 can abut against the first contact portion 11a along the first direction, making the second contact portion 1211 easier to deform and reducing the deformation of the first contact portion 11a on the housing 11, thereby improving the stress concentration of the housing 11.

[0055] For example, the first direction can be perpendicular to the sliding direction of the sliding part 121.

[0056] In some embodiments, please refer to Figures 3 to 5 , Figures 8 to 9 The extension direction of the second contact portion 1211 is the same as the sliding direction of the sliding portion 121.

[0057] Thus, when the movable arm 12 slides along the sliding direction of the sliding part 121 to the maximum stroke position or the minimum stroke position, that is, when it switches to the idle state, since the extension direction of the second contact part 1211 is consistent with the sliding direction of the sliding part 121, the contact path between the first contact part 11a and the second contact part 1211 can be extended, thereby improving the stability and reliability of the contact.

[0058] For example, one end of the second contact portion 1211 is disposed on the groove wall of the relief groove 121a on the side along the sliding direction, and the other end of the second contact portion 1211 extends along the sliding direction. It can be understood that during the process of the second contact portion 1211 gradually coming into contact with the first contact portion 11a, in addition to the contact force, the second contact portion 1211 is also subjected to a force from the first contact portion 11a along the sliding direction. By limiting the connection position between the second contact portion 1211 and the relief groove 121a and the extension direction of the second contact portion 1211 being the same as the sliding direction, the force on the second contact portion 1211 from the first contact portion 11a along the sliding direction is made tensile stress. This can improve the situation where the second contact portion 1211 is subjected to shear stress along the sliding direction during the process of gradually coming into contact with the first contact portion 11a, thereby improving the reliability and stability of the second contact portion 1211.

[0059] In other embodiments, the extending direction of the second contact portion 1211 intersects the sliding direction of the sliding portion 121.

[0060] In some embodiments, please refer to Figures 3 to 5 , Figures 8 to 9 The second contact portion 1211 includes a free section 12111 and a connecting section 12112. The connecting section 12112 connects the free section 12111 to the groove wall of the clearance groove 121a. The free section 12111 protrudes from the clearance groove 121a along a first direction toward the first contact portion 11a.

[0061] The free segment 12111 protrudes from the clearance groove 121a along the first direction toward the first contact portion 11a. In other words, part of the free segment 12111 protrudes from the side wall of the sliding portion 121 along the first direction, which can increase the degree of contact between the second contact portion 1211 and the first contact portion 11a, i.e. the amount of interference, and improve the stability effect on the movable arm 12.

[0062] In some embodiments, please refer to Figure 4 and Figure 9 A groove 1211a is formed on the side of the second contact portion 1211 that is away from the first contact portion 11a.

[0063] In other words, the side of the second contact portion 1211 opposite to the first contact portion 11a is recessed into the side wall of the sliding portion 121 along the first direction, which can reduce the structural strength of the second contact portion 1211 at that location. This is beneficial for the deformation of the free section 12111 of the second contact portion 12111 relative to the connecting section 12112. After deformation, the space of the groove 1211a can also avoid some structures inside the housing 11.

[0064] For example, the smooth transition between the groove walls of the groove 1211a can reduce stress concentration during elastic deformation.

[0065] In some embodiments, please refer to Figure 3 , Figure 4 , Figure 5 and Figure 9 The free segment 12111 includes a guide unit 12111a and an abutment unit 12111b. The guide unit 12111a is smoothly connected between the abutment unit 12111b and the connecting segment 12112.

[0066] The abutment unit 12111b is used to abut against the first contact portion 11a. The smooth transition connection can reduce stress concentration points.

[0067] When the first contact portion 11a and the second contact portion 1211 approach each other, the guide unit 12111a is used to guide the first contact portion 11a along the first direction so as to guide the first contact portion 11a to abut against the abutting unit 12111b.

[0068] For example, the free segment 12111 has a guide surface and an abutment surface on the side of the first contact portion 11a along the first direction, the connecting segment 12112 has a connecting surface on the side of the first contact portion 11a along the first direction, the abutment surface is located between the connecting surface and the first contact portion 11a along the first direction, and the guide surface smoothly connects the guide surface and the connecting surface.

[0069] In some embodiments, please refer to Figures 3 to 6 ,as well as Figure 8 The housing 11 has a telescopic cavity 11b and an extension 11c communicating with the telescopic cavity 11b. The sliding part 121 can extend out of the telescopic cavity 11b or retract into the telescopic cavity 11b through the extension 11c. The first contact part 11a is provided in the telescopic cavity 11b and is located at the edge of the extension 11c.

[0070] Correspondingly, the second contact portion 1211 is provided in the portion of the sliding portion 121 located in the telescopic cavity 11b. During the process of switching from the clamping state to the idle state, the second contact portion 1211 moves from the inside to the outside towards the extension opening 11c along with the sliding portion 121. When the second contact portion 1211 moves to the inside of the extension opening 11c, it abuts against the first contact portion 11a and generates elastic deformation, and the movable arm 12 becomes idle.

[0071] Thus, the first contact portion 11a and the second contact portion 1211 are both located inside the housing 11 in the clamping state and the unloaded state, which can improve the appearance of the product. At the same time, by placing the first contact portion 11a at the edge of the protrusion 11c, the stability of the movable arm 12 at the protrusion 11c position can be enhanced, and the situation where the movable arm 12 is prone to wobbling relative to the housing 11 at the protrusion 11c position can be improved.

[0072] In some embodiments, in the idle state, the movable arm 12 slides along the sliding direction of the sliding portion 121 to the maximum stroke position, and the second contact portion 1211 abuts against the first contact portion 11a. In the clamping state, the movable arm 12 slides along the sliding direction of the sliding portion 121 to the minimum stroke position or any position between the maximum stroke position and the minimum stroke position, and the second contact portion 1211 avoids the first contact portion 11a.

[0073] For example, the clamping bracket 10 in this embodiment is a gravity bracket. The following description uses the clamping bracket 10 as an example of a gravity bracket.

[0074] Understandably, when the gravity support is not in use (i.e., in an empty state), the movable arm 12 slides to its maximum stroke position along the sliding direction of the sliding part 121. When an electronic device is placed on the gravity support, the movable arm 12 retracts inward along the sliding direction of the sliding part 121 due to the weight of the electronic device, until it clamps the electronic device. At this point, the movable arm 12 switches to the clamping state. Therefore, in the clamping state, the extension and retraction stroke of the movable arm 12 depends on the size of the electronic device. The movable arm 12 can be slid to its minimum stroke position to clamp the electronic device, or it can be slid to any position between the maximum and minimum stroke positions to clamp the electronic device; there are no restrictions on this.

[0075] The clamping bracket 10 in this embodiment can also be other types of clamping brackets in which the movable arm 12 slides to the maximum stroke position along the sliding direction of the sliding part 121 in the idle state, and there is no limitation here.

[0076] In some embodiments, in the idle state, the movable arm 12 slides along the sliding direction of the sliding portion 121 to the minimum stroke position, and the second contact portion 1211 abuts against the first contact portion 11a. In the clamping state, the movable arm 12 slides along the sliding direction of the sliding portion 121 to the maximum stroke position or any position between the maximum stroke position and the minimum stroke position, and the second contact portion 1211 avoids the first contact portion 11a.

[0077] It should be noted that the clamping bracket 10 in this embodiment can be any clamping bracket in which the movable arm 12 slides to the minimum stroke position along the sliding direction of the sliding part 121 in an unattended state.

[0078] For example, the clamping bracket 10 in this embodiment is a non-gravity bracket. A non-gravity bracket refers to a clamping bracket other than a gravity bracket, such as a magnetic bracket, a wireless charging bracket, etc.

[0079] In this embodiment, when the clamping bracket 10 is not in use (i.e., in an empty state), the movable arm 12 slides along the sliding direction of the sliding part 121 to the minimum stroke position. When it is necessary to clamp the electronic device, the user can drive the movable arm 12 to slide along the sliding direction of the sliding part 121 to the maximum stroke position through a button or other feedback element, providing a larger clamping space for the electronic device. After the electronic device is placed, the button or other feedback element is deactivated, the movable arm 12 is in its natural state and retracts into the housing 11 until the clamping part 122 clamps the electronic device. Similarly, the extension and retraction stroke of the movable arm 12 in the clamping state depends on the size of the electronic device. It can clamp the electronic device exactly when the movable arm 12 extends to the maximum stroke position, or it can clamp the electronic device at any position between the maximum stroke position and the minimum stroke position. There is no limitation here.

[0080] In some embodiments, please refer to Figure 8 The clamping bracket 10 includes a gear 13. The gear 13 is rotatably disposed within the housing 11. The sliding portion 121 is formed with a rack structure 121b arranged along the sliding direction. The rack structure 121b of each movable arm 12 is respectively engaged with the gear 13 for transmission.

[0081] The gear 13 is rotatably disposed within the housing 11, meaning that the gear 13 can rotate relative to the housing 11.

[0082] Each movable arm 12 has a rack structure 121b that is driven by a gear 13. The rack structure 121b meshes with the gear 13, so that the gear 13 can drive multiple movable arms 12 to extend and slide along the sliding direction at the same time through its own rotation.

[0083] For example, the clamping bracket 10 also includes a first elastic element 14. The movable arm 12 is provided with a fixing unit 121d. One end of the first elastic element 14 is sleeved on the fixing unit 121d, and the other end abuts against the housing 11 in the sliding direction. In the clamping state, the first elastic element 14 is compressed. In the process of switching from the clamping state to the idle state, the elastic force of the first elastic element 14 drives the movable arm 12 connected to it to extend outward in the sliding direction, and then drives other movable arms 12 to extend outward in the sliding direction through the gear 13.

[0084] In some embodiments, please refer to Figure 5 and Figure 6 At least one sliding portion 121 of the movable arm 12 has a stop protrusion 121c. A stop rib 11d is formed inside the housing 11. The stop protrusion 121c and the stop rib 11d stop and cooperate to limit the movable arm 12 in the sliding direction.

[0085] For example, at least one sliding portion 121 of the movable arm 12 extends along a first direction to form a stop protrusion 121c. A stop rib 11d protruding along the first direction is formed inside the housing 11.

[0086] The stop protrusion 121c and the stop rib 11d cooperate to limit the sliding arm 12 in the sliding direction, at which time the sliding arm 12 can be in an unloaded state. The cooperation between the stop protrusion 121c and the stop rib 11d can improve the situation where the sliding arm 12 disengages from the housing 11.

[0087] In some embodiments, please refer to Figure 5 and Figure 6 The clamping bracket 10 also includes a second elastic element 15, a button 16, and a locking element 17. One end of the second elastic element 15 is connected to the locking element 17, and the other end is connected to the housing 11. The gear 13 has a locked state and a free state. In the free state, the button 16 drives the locking element 17 to compress the second elastic element 15 and avoid the gear 13. In the locked state, the button 16 resets, and the second elastic element 15 drives the locking element 17 to reset and lock the gear 13.

[0088] In this way, the components inside the housing 11 can be limited and fixed, thus improving the situation where the clamping bracket 10 makes abnormal noises during shaking.

[0089] In some embodiments, please refer to Figure 3 , Figure 4 and Figure 6 At least a portion of the inner wall of the housing 11 extends along a first direction toward the second contact portion 1211 to form the first contact portion 11a.

[0090] It should be noted that the first contact portion 11a can be formed on a portion of the inner wall of the housing 11, or the entire inner wall can be formed on the first contact portion 11a; there is no limitation here.

[0091] For example, the first contact portion 11a is integrally formed with the housing 11.

[0092] For example, the first contact portion 11a is a reinforcing rib formed on the edge of the protrusion 11c.

[0093] Thus, the first contact portion 11a is part of the housing 11, making the structure of the housing 11 simpler, reducing production difficulty, and strengthening the connection between the housing 11 and the first contact portion 11a.

[0094] In some embodiments, the second contact portion 1211 is integrally formed with the sliding portion 121.

[0095] This reduces production difficulty and strengthens the connection between the second contact part 1211 and the sliding part 121.

[0096] In some embodiments, please refer to Figure 6 , Figure 7 and Figure 8 The clamping bracket 10 also includes a base 18 and an adjusting member 19. The adjusting member 19 has a positioning protrusion 19a. The base 18 has multiple positioning grooves 18a. The adjusting member 19 is connected to the housing 11. The base 18 is slidable relative to the housing 11 in the top-to-bottom direction. One of the positioning grooves 18a of the base 18 engages with the positioning protrusion 19a to limit the position of the base 18 in the top-to-bottom direction. The user can drive the base 18 to adjust the positioning groove 18a that engages with the positioning protrusion 19a, thereby adjusting the position of the base 18 in the top-to-bottom direction and improving its compatibility with electronic devices.
