Description

Technical Field

[0001] This utility model relates to the field of mobile phone holder technology, and in particular to a mobile phone holder. Background Technology

[0002] A press-type phone holder is a device that uses a mechanical pressing action to clamp and release a phone. The user presses a trigger block on the holder, which retracts into the housing, releasing the clamping arms. Simultaneously, the clamping arms open or close, allowing for quick clamping and release of the phone. The trigger block of the press-type phone holder is exposed on the front housing, and a return spring is located between the trigger block and the rear housing. During triggering, the trigger block needs to completely separate from the clamping arms, requiring a certain longitudinal travel space. This necessitates sufficient thickness between the front and rear housings to accommodate its movement, resulting in existing press-type phone holders being excessively thick. Utility Model Content

The side of the first clamping component and the second clamping component away from the triggering component is provided with a receiving groove corresponding to the limiting block. When the triggering component drives the limiting block to slide relative to the first clamping component and the second clamping component, the limiting block slides into the receiving groove and cancels the limiting of the first clamping component and the second clamping component.

[0007] Preferably, the first clamping arm has at least one first clearance groove away from the triggering component, and the second clamping arm has a second clearance groove corresponding to the first clearance groove. The openings of the first clearance groove and the second clearance groove are opposite each other. A first positioning post is provided at the end of the first clearance groove away from the opening, and a second positioning post is provided at the end of the second clearance groove away from the opening. One end of the clamping spring is connected to the first positioning post, and the other end is connected to the second positioning post. When the first driving block and the second driving block approach each other, the first clamping arm and the second clamping arm move away from each other.

[0008] Preferably, the phone holder further includes a transmission gear, which is disposed within the housing and rotatably connected to the housing. The first clamping arm and the second clamping arm approach each other in the clamping direction. The first driving block includes a first pressing part and a first connecting part.

[0013] Preferably, the second housing has a quick-release interface on the side away from the first housing.

[0014] Compared with the prior art, the mobile phone holder provided by this utility model has the following beneficial effects: 1. A mobile phone holder provided in this embodiment of the present invention includes a housing, a first clamping assembly, a second clamping assembly, a clamping spring, and a triggering device; the first clamping assembly and the second clamping assembly are convexly connected; the triggering device includes a return spring, a triggering assembly, and a limiting block, the limiting block being disposed between the first clamping assembly and the second clamping assembly, one end of the triggering assembly being connected to the limiting block, and the other end passing through the housing and exposed, the return spring being disposed on the side of the limiting block away from the triggering assembly and connected to the inner wall of the housing, the triggering device driving the limiting block to move along the axial direction of the return spring, and one end of the clamping spring being connected to the first clamping assembly and the second clamping assembly. A clamping component is provided at one end, and a second clamping component is connected at the other end, allowing the first and second clamping components to move closer together. A receiving groove is provided on the side of the first and second clamping components away from the trigger component, corresponding to a limiting block. When the trigger component causes the limiting block to slide relative to the first and second clamping components, the limiting block slides into the receiving groove and releases its limiting effect on the first and second clamping components. When the first and second clamping components move away from each other, a return spring causes the limiting block to return to the position between the first and second clamping components, thus limiting their movement. This embodiment cleverly integrates the movement trajectory of the limiting block, which would otherwise require additional housing space, into the structure of the clamping component itself. The receiving groove is directly machined into the inner side of the clamping component, providing embedding space for the limiting block when it needs to retract, thereby avoiding the need to create a separate chamber inside the housing or thicken the housing wall to accommodate the limiting block.

[0015] 2. The first clamping assembly provided in this embodiment of the present invention includes a first driving block and a first clamping arm connected to each other. Both the first driving block and the first clamping arm are partially housed within the housing, with the end of the first driving block away from the first clamping arm exposed on one side of the housing, and the end of the first clamping arm away from the first driving block exposed on the other side of the housing. The second clamping assembly includes a second driving block and a second clamping arm connected to each other. Both the first driving block and the first clamping arm are partially housed within the housing, and the first driving block and the second driving block are arranged opposite to each other. The first clamping arm includes a first main body segment, a first contact segment, and a second... The first main body segment has a first contact segment corresponding to the limiting block on the side near the second clamping arm. The side away from the second clamping arm is bent towards the second clamping arm to form the first limiting segment. The second clamping arm includes a second main body segment, a second contact segment, and a second limiting segment. The second main body segment has a second contact segment corresponding to the limiting block on the side near the second clamping arm. The side away from the second clamping arm is bent towards the second clamping arm to form the second limiting segment. Partial areas of the first and second contact segments are recessed to form receiving grooves. The limiting block is disposed between the first and second contact segments to limit the movement of the first and second clamping arms. The receiving groove is directly part of the contact segment of the clamping arm body, rather than an additional component, reducing the number of parts and simplifying the assembly process. During manufacturing, materials or processes more suitable for its function can be adopted. For example, materials with a lower coefficient of friction can be used for the contact section, while elasticity or anti-slip treatment can be added to the limiting section. This allows a single clamping arm assembly to efficiently and reliably complete the functions of power transmission, limiting interaction, and terminal clamping simultaneously, achieving the optimal layout of the structure within a limited space and improving the overall performance and durability of the phone holder.

[0016] 3. In this embodiment of the invention, the thickness of the limiting block along the axial direction of the reset spring is less than or equal to the depth of the receiving groove. The limiting block can be completely embedded into the groove-shaped space formed by the recessed portions of the two contact sections. Its outer surface can be completely sunk into the groove, thereby ensuring that its overall contour is completely freed from the clamping of the limiting member by the two clamping arms.

[0017] 4. The first clamping arm provided in this embodiment of the utility model has at least one first clearance groove away from the triggering component, and the second clamping arm has a second clearance groove corresponding to the first clearance groove. The openings of the first clearance groove and the second clearance groove are opposite each other. A first positioning post is provided at the end of the first clearance groove away from the opening, and a second positioning post is provided at the end of the second clearance groove away from the opening. One end of the clamping spring is connected to the first positioning post, and the other end is connected to the second positioning post. When the first driving block and the second driving block approach each other, the first clamping arm and the second clamping arm move away from each other; when the first clamping arm and the second clamping arm approach each other, the first driving block and the second driving block move away from each other. During assembly, it is only necessary to put the two ends of the clamping spring into or hang them on the two positioning posts respectively, which is intuitive and simple to operate. Since the spring is restricted to move within the range of the clearance groove, its entire working stroke will not encroach on the space of the clamping arm used to arrange the driving block, triggering device and other key components.

[0018] 5. The mobile phone holder provided in this embodiment of the utility model also includes a transmission gear, which is rotatably connected to the housing. The first clamping arm and the second clamping arm approach each other in the clamping direction. The first driving block includes a first pressing part and a first connecting part. The first connecting part is connected to the first clamping arm and extends along the clamping direction to form a first pressing part exposed outside the housing. A first transmission groove is formed on the first connecting part. The second driving block includes a second pressing part and a second connecting part. The second connecting part is connected to the second clamping arm and extends along the clamping direction to form a second pressing part exposed outside the housing. A second transmission groove is formed on the second connecting part. One end of the transmission gear is set in the first transmission groove, and the other end of the transmission gear is set in the second transmission groove. The transmission gear is respectively connected to the first driving block and the second driving block. The user only needs to press either driving block with one finger to automatically drive the other driving block to move synchronously in the opposite direction through gear transmission, thereby driving the clamping arms on both sides to achieve symmetrical opening. This makes the operation of placing the mobile phone with one hand very simple and reliable, and lowers the operation threshold. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0029] It should be noted that the terms "first" and "second" in the specification and claims of this utility model are used to distinguish different objects, rather than to describe a specific order.

[0030] It should be noted that when an element is said to be "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is said to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "first," "second," and similar expressions used in this document are for illustrative purposes only.

[0034] Please combine Figure 1 and Figure 2The first embodiment of this utility model provides a mobile phone holder 10, which includes a housing 1, a first clamping assembly 2, a second clamping assembly 3, a clamping spring 4, and a triggering device 5. The first clamping assembly 2 and the second clamping assembly 3 are connected by a drive. The triggering device 5 includes a return spring 51, a triggering assembly 52, and a limiting block 53. The limiting block 53 is disposed between the first clamping assembly 2 and the second clamping assembly 3. One end of the triggering assembly 52 is connected to the limiting block 53, and the other end is exposed through the housing 1. The return spring 51 is disposed on the side of the limiting block 53 away from the triggering assembly 52 and is connected to the inner wall of the housing 1. The triggering device 5 and the return spring 51 respectively abut against the opposite sides of the limiting block 53. One end of the clamping spring 4 is connected to the first clamping assembly 2, and the other end is connected to the second clamping assembly 3, so that the first clamping assembly 1... 2. The first clamping component 2 and the second clamping component 3 move closer to each other. The side of the first clamping component 2 and the second clamping component 3 away from the triggering component 52 is provided with a receiving groove 6 corresponding to the limiting block 53. When the first clamping component 2 and the second clamping component 3 are moved away from each other by external force, a gap is formed between the first clamping component 2 and the second clamping component 3. The reset spring 51 drives the limiting block 53 to move to the gap between the first clamping component 2 and the second clamping component 3, thereby limiting the first clamping component 2 and the second clamping component 3. When the triggering component is pressed by the triggering component 52 and drives the limiting block 53 to slide relative to the first clamping component 2 and the second clamping component 3, the limiting block 53 slides into the receiving groove 6 and cancels the limitation on the first clamping component 2 and the second clamping component 3. The first clamping component 2 and the second clamping component 3 move closer to each other under the tension of the clamping spring 4.

[0035] Understandably, in the layout of the clamping mechanism and triggering device 5, traditional mobile phone holders 10 usually require a separate space to accommodate the triggering limiting component. This often leads to an increase in the overall thickness of the housing 1, which is not conducive to the design of a thin and portable holder. Especially in usage scenarios that pursue miniaturization and easy storage, an excessively thick housing 1 not only affects aesthetics but also increases the inconvenience of carrying and storing. Specifically, in this embodiment, a receiving groove 6 is provided on the first clamping component 2 and the second clamping component 3, and the receiving groove 6 is used as the moving space for the limiting block 53. When the holder is in the open standby state, the limiting block 53 is located between the two clamping components, preventing them from moving closer to each other. When the user places a mobile phone or electronic device on it and presses the triggering component 52, the triggering component 52 drives the limiting block 53 to move axially along the return spring 51 until the limiting block 53 slides into the preset receiving groove 6 on the clamping component. At this point, the limiting block 53 disengages from the clamping assembly, and the clamping spring 4 then drives the first clamping assembly 2 and the second clamping assembly 3 to close together, completing the clamping of the mobile phone. This embodiment cleverly integrates the movement trajectory of the limiting block 53, which originally required additional space in the housing 1, into the structure of the clamping assembly itself. The receiving groove 6 is directly machined into the inner side of the clamping assembly, providing embedding space for the limiting block 53 when it needs to retract, thus avoiding the need to separately create a cavity inside the housing 1 or thicken the walls of the housing 1 to accommodate the limiting block 53. For example, in the thickness direction of the bracket, since there is no need to reserve a dedicated thickness space for the full movement of the limiting block 53, the distance between the front and rear covers of the housing 1 is significantly reduced. This not only makes the overall shape of the mobile phone bracket 10 thinner and lighter.

[0036] Furthermore, since the receiving groove 6 moves along with the clamping assembly, it maintains a compatible relative position with the limiting block 53 throughout the bracket's operation, ensuring that the limiting block 53 can slide in and out accurately and smoothly, thus maintaining the reliability of the triggering and resetting actions. This embodiment employs an integrated space utilization method, effectively optimizing the internal space layout of the bracket while ensuring the complete realization of the clamping and releasing functions.

[0037] Specifically, please combine Figure 2 , Figure 3 , Figure 4 and Figure 7The first clamping assembly 2 includes a first driving block 21 and a first clamping arm 22 connected to each other. Both the first driving block 21 and the first clamping arm 22 are partially housed within the housing 1. The end of the first driving block 21 away from the first clamping arm 22 protrudes from one side of the housing 1, and the end of the first clamping arm 22 away from the first driving block 21 protrudes from the other side of the housing 1. The second clamping assembly 3 includes a second driving block 31 and a second clamping arm 32 connected to each other. Both the first driving block 21 and the first clamping arm 22 are partially housed within the housing 1. The first driving block 21 and the second driving block 31 are arranged opposite to each other, as are the first clamping arm 22 and the second clamping arm 32. The first clamping arm 22 includes a first main body segment 221, a first contact segment 222, and a first limiting segment 223. A first contact segment 222 is provided on the side near the second clamping arm 32 corresponding to the limiting block 53, and the side away from the second clamping arm 32 is bent towards the direction of the second clamping arm 32 to form a first limiting segment 223. The second clamping arm 32 includes a second main body segment 321, a second contact segment 322 and a second limiting segment 323. The second main body segment 321 is provided on the side near the second clamping arm 32 corresponding to the limiting block 53, and the side away from the second clamping arm 32 is bent towards the direction of the second clamping arm 32 to form a second limiting segment 323. Partial areas of the first contact segment 222 and the second contact segment 322 are recessed to form a receiving groove 6. The limiting block 53 is disposed between the first contact segment 222 and the second contact segment 322 to limit the first clamping arm 22 and the second clamping arm 32.

[0038] Understandably, the main body segment, as the core skeleton of the clamping arm, is responsible for connecting with the first drive block 21 or the second drive block 31, and effectively transmitting the thrust from the drive block or the tension from the clamping spring 4 to the entire clamping arm. A contact segment is specifically located on the side of the main body segment closest to the other clamping arm, with a portion of its area recessed inwards, forming a receiving groove 6 for accommodating the limiting block 53. The contact segment can be locally reinforced or lubricated for the sliding engagement with the limiting block 53, reducing wear. The limiting segment is formed by bending the side of the main body segment away from the other clamping arm inwards, and its bending shape directly constitutes the clamping surface that contacts the side of the phone. Taking the first clamping arm 22 as an example, the bending design of its first limiting segment 223 makes the point of application of the clamping force closer to the center of the phone, helping to form a more stable torque and preventing the phone from shaking or rotating in the bracket. Meanwhile, the first contact section 222 and the receiving groove 6 formed thereon ensure that the limiting block 53 can move within a precisely defined track, avoiding interference between the limiting block 53 and other parts of the clamping arm during operation, thereby improving the smoothness and reliability of the triggering and resetting actions. The second clamping arm 32 has the same advantages and will not be elaborated further here.

[0039] Furthermore, since the receiving groove 6 is directly part of the contact section of the clamping arm body rather than an additional component, the number of parts is reduced, simplifying the assembly process. During manufacturing, materials or processes more suitable for its function can be used; for example, a material with a lower coefficient of friction can be considered for the contact section, while elasticity or anti-slip treatment can be added to the limiting section. This allows a single clamping arm assembly to efficiently and reliably perform power transmission, limiting interaction, and terminal clamping functions simultaneously, achieving an optimized structural layout within a limited space and improving the overall performance and durability of the phone holder 10.

[0040] Specifically, the thickness of the limiting block 53 along the axial direction of the return spring 51 is less than or equal to the depth of the receiving groove 6. Understandably, when the user presses the trigger assembly 52 into the housing 1, the limiting block 53 connected to it is pushed and moves along the compression direction of the return spring 51. At this time, the first contact segment 222 and the second contact segment 322 on the first clamping arm 22 and the second clamping arm 32 are relatively stationary or in an initial separated state, and the receiving groove 6 on them is directly opposite the movement trajectory of the limiting block 53. Since the maximum thickness of the limiting block 53 is not greater than the depth of the receiving groove 6 in that direction, the limiting block 53 can be completely embedded into the groove-shaped space formed by the recessed portions of the two contact segments. Its outer surface can be completely sunk into the groove, thereby ensuring that its overall contour is completely freed from the clamping of the limiting member by the two clamping arms.

[0041] Furthermore, once the limiting block 53 is fully retracted into the receiving groove 6, it no longer constitutes a physical obstruction to any part of the first clamping arm 22 and the second clamping arm 32. Subsequently, under the restoring force of the clamping spring 4, the first clamping arm 22 and the second clamping arm 32 can move towards the center until the first limiting segment 223 and the second limiting segment 323 are firmly in contact and clamp the two sides of the phone. The clamping force is provided by the clamping spring 4. Conversely, when it is necessary to remove the phone, the user pushes the drive block outward to separate the clamping arms. When the separation is such that the receiving groove 6 is aligned with the limiting block 53 again, under the action of the return spring 51, the limiting block 53 is pushed out of the groove and reset to between the two clamping arms. With the solid obstruction formed by its thickness, the clamping arms are in an open state, ready for the next clamping operation.

[0042] Furthermore, please combine Figure 3 and Figure 4The first clamping arm 22 has at least one first clearance groove 73 away from the trigger component 52, and the second clamping arm 32 has a second clearance groove 74 corresponding to the first clearance groove. The openings of the first clearance groove 73 and the second clearance groove 74 are opposite each other. A first positioning post 71 is provided at the end of the first clearance groove 73 away from the opening, and a second positioning post 72 is provided at the end of the second clearance groove 74 away from the opening. One end of the clamping spring 4 is connected to the first positioning post 71, and the other end is connected to the second positioning post 72. When the first driving block 21 and the second driving block 31 move closer to each other, the first clamping arm 22 and the second clamping arm 32 move away from each other.

[0043] It should be understood that by creating clearance grooves 7 on the first clamping arm 22 and the second clamping arm 32, and setting first positioning posts 71 and second positioning posts 72 at both ends of the groove to connect the clamping spring 4, the clearance groove 7 is a recessed area on the main body of the clamping arm. Its primary function is to provide dedicated space for the clamping spring 4 to accommodate and move. Placing the spring in this groove can limit the lateral swing or twisting that may occur during the compression and extension of the spring, ensuring that its force line always acts in the expected direction, that is, always causing the first positioning post 71 and the second positioning post 72 to move closer to each other. The first positioning post 71 and the second positioning post 72 are respectively fixed at opposite ends of the clearance groove 7, serving as reliable anchor points at both ends of the spring. Integrating the connection point of the spring into the clamping arm body structure simplifies the assembly process. During assembly, simply slip or hang the two ends of the clamping spring 4 onto the two positioning posts, making the operation intuitive and simple. Since the spring is restricted to move within the range of the clearance groove 7, its entire working stroke will not encroach on the space of the clamping arm used to arrange other key components such as the drive block and the triggering device 5.

[0044] Furthermore, the phone holder 10 also includes a transmission gear 8, which is rotatably connected to the housing 1. The first clamping arm 22 and the second clamping arm 32 approach each other in the clamping direction. The first driving block 21 includes a first pressing part 211 and a first connecting part 212. The first connecting part 212 is connected to the first clamping arm 22. The first connecting part 212 extends along the clamping direction to form the first pressing part 211 exposed outside the housing 1. A first transmission groove 213 is formed on the first connecting part 212. The second driving block 31 includes... It includes a second pressing part 311 and a second connecting rod 522312. The second connecting rod 522312 is connected to the second clamping arm 32. The second connecting rod 522312 extends along the clamping direction to form the second pressing part 311 exposed outside the housing 1. A second transmission groove 313 is provided on the second connecting rod 522312. One end of the transmission gear 8 is set in the first transmission groove 213, and the other end of the transmission gear 8 is set in the second transmission groove 313. The transmission gear 8 is connected to the first driving block 21 and the second driving block 31 respectively.

[0045] Understandably, the first drive block 21 consists of an exposed first pressing part 211 and a first connecting part 212 extending into the housing 1, and the structure of the second drive block 31 is symmetrical to that of the first drive block 21. A first transmission groove 213 and a second transmission groove 313 are formed on the connecting rod 522 of the two drive blocks along their direction of movement. One end of the transmission gear 8 meshes in the first transmission groove 213, and the other end meshes in the second transmission groove 313. For example, when the user applies force to the second pressing part 311, causing it to move inward, the second transmission groove 313 on the second connecting rod 522 312 will drive the meshing transmission gear 8 to rotate. Since the transmission gear 8 is a rigidly connected single part, its rotational motion is transmitted to the other end meshing with the first transmission groove 213, thereby pushing the first drive block 21 to move at the same speed but in the opposite direction. The user only needs to press either drive block with a single finger to automatically drive the other drive block to move synchronously in the opposite direction through gear transmission, thereby driving the two clamping arms to achieve a symmetrical opening action. This makes it very simple and reliable to place the phone with one hand, lowering the barrier to entry.

[0046] In one implementation, please refer to Figure 3 and Figure 4 The first transmission groove 213 is provided with a first transmission tooth 214 on the side of the first transmission groove 213 near the second clamping arm 32, and the second transmission groove 313 is provided with a second transmission tooth 314 on the side of the second transmission groove 313 away from the first clamping arm 22, corresponding to the transmission gear 8.

[0047] Understandably, by specifically defining the positions of the first transmission tooth 214 and the second transmission tooth 314 on their respective transmission grooves, design redundancy of the transmission teeth is avoided. When the user intends to open the clamping arm, for example by pressing the first pressing part 211 of the first drive block 21 inward with a finger, the applied thrust is directed to move the first drive block 21 as a whole toward the second clamping arm 32. At this time, the tooth surface of the first transmission tooth 214, located "on the side of the first transmission groove 213 near the second clamping arm 32," faces the thrust from the direction of movement of the first drive block 21. This thrust acts on the teeth of the transmission gear 8 meshing with it through the tooth surface of the first transmission tooth 214. Simultaneously, the gear rotates due to the force from the first transmission tooth 214, and the teeth on its other side drive the second transmission tooth 314. Since the second transmission tooth 314 is located on the side of the second transmission groove 313 away from the first clamping arm 22, when the gear rotates and pushes the tooth, its force direction is exactly to drive the second drive block 31 toward the opposite side of the first clamping arm 22, that is, inward. Regardless of which side of the drive block is pressed, or when the clamping arm resets under the action of the spring and drives the drive block to move outward, the meshing force between the transmission gear 8 and the transmission teeth on both sides is always along the clamping direction of the drive block.

[0048] In another embodiment, transmission teeth are provided on the opposite sides of the first transmission groove 213 and the second transmission groove 313 corresponding to the transmission gear 8. It should be understood that by providing transmission teeth (not shown) on both sides of the first transmission groove 213 and the second transmission groove 313, the force transmission between the transmission gear 8 and the drive block is accomplished through specially designed tooth surface meshing in both directions of the reciprocating motion of the drive block, making the transmission process more stable.

[0049] Specifically, please refer to Figure 2 and Figure 4 The housing 1 includes a first housing 11 and a second housing 12, which are detachably connected and directly define the accommodating space. The trigger assembly 52 includes a trigger part 521 and a connecting rod 522. The trigger part 521 is exposed outside the housing 1. The first housing 11 has an opening corresponding to the trigger part 521. One end of the connecting rod 522 is connected to the limiting block 53, and the other end is connected to the trigger part 521.

[0050] Understandably, housing 1 consists of a detachable first housing 11 and a second housing 12. When the bracket requires internal cleaning or a part needs replacement, maintenance personnel can easily disassemble housing 1 and reassemble it, greatly improving the maintainability of the product and extending its effective service life. The trigger part 521 is the part that the user or mobile phone directly contacts and presses, and it is exposed outside housing 1; the connecting rod 522 is located inside housing 1, with one end connected to the limiting block 53 and the other end connected to the trigger part 521. The first housing 11 has a dedicated opening corresponding to the trigger part 521. The trigger assembly 52, as a whole component, passes through housing 1 through the opening. When the trigger assembly 52 is pressed, at least part of the trigger part 521 can retract into the opening.

[0051] Specifically, the phone holder 10 also includes a base 13, which is located at the end of the housing 1 away from the trigger component 52. When the phone is placed on the holder, and the two clamping arms close to secure the left and right edges of the phone, the bottom edge of the phone rests on the base 13. The base 13 directly bears all or most of the weight of the phone, eliminating the possibility of the phone completely falling off the bottom of the holder.

[0052] Specifically, a quick-release interface 14 is provided on the side of the second housing 12 away from the first housing 11. The quick-release interface 14 can be a standardized mechanical connection structure, such as a dovetail groove, a bayonet type, or a magnetic adsorption locking mechanism. For users, they only need to purchase a phone holder 10 body equipped with this quick-release interface 14, and can select the corresponding fixing accessories with matching interfaces according to different usage scenarios. Users do not need to remove any screws or tools; they only need to operate the release mechanism of the quick-release interface 14 to remove the holder body from the current fixing accessory within seconds and quickly install it onto another accessory that has been pre-fixed in the target position.

[0053] 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.
