Description

Technical Field

[0001] This utility model belongs to the field of motorcycle parts technology, and in particular relates to an adjustable motorcycle windshield mounting bracket. Background Technology

[0002] In traditional motorcycle windshield bracket structures, the fixed structure cannot be adjusted in height according to rider height differences, riding posture changes, or different usage scenarios. This results in a fixed relative position between the windshield and the rider, and the fixed design means the frontal area cannot dynamically adapt to changes in riding posture. Secondly, while existing adjustable brackets offer some adjustment capabilities, they generally suffer from limited adjustment range and high tool dependence, making it impossible to quickly respond to wind resistance adjustment needs under different conditions during riding. For example, in high-speed motorcycle cruising scenarios, riders need to adjust the windshield height in real time according to road undulations or crosswind intensity to reduce the drag coefficient. Existing adjustment mechanisms, due to the limited length of the sliding rail, cannot cover the entire posture range from upright riding to leaning forward for acceleration. At the same time, the rigid connection between the adjustment handle and the bracket requires tools such as hex wrenches for unlocking, forcing the rider to stop and perform multiple disassembly and assembly steps. This process not only interrupts the continuity of riding but also causes stress concentration in the locking mechanism due to insufficient tool operation precision, resulting in micro-deformation of the guide rail surface.

[0003] If the above issues are not addressed, the insufficient degree of freedom in adjusting the mechanical structure will directly limit the boundary conditions for aerodynamic optimization, resulting in an ineffective balance between wind resistance and torque at high speeds, increasing the handling load on the handlebars. Tool-dependent operating modes will prolong adjustment response time; in emergency lane changes or sudden crosswinds, riders will be unable to adjust their windshield posture in time, leading to reduced vehicle stability margin. Frequent disassembly and assembly operations will also accelerate the wear of the locking thread pairs, shortening the fatigue life of the bracket components.

[0004] To address the aforementioned issues, existing technologies urgently need improvement. Utility Model Content

[0005] The purpose of this utility model is to provide an adjustable motorcycle windshield mounting bracket, which has the advantages of convenient operation, quick adjustment and reliable fixation without tools, and effectively improves the adaptability of the windshield position and riding safety, so as to solve the problem that traditional motorcycle windshield brackets cannot be adjusted or are inconvenient to adjust.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows: an adjustable motorcycle windshield mounting bracket, comprising an upper bracket, a lower bracket, and an adjustment assembly, wherein the upper bracket is mounted on the lower bracket in a controllable manner that slides relative to the lower bracket along the X direction; the adjustment assembly includes an adjustment handle disposed on the upper bracket, the adjustment handle being driven to approach and connect to the lower bracket, so that the upper bracket is locked and limited to the lower bracket; or, the adjustment handle being driven away from the lower bracket to release the limitation on the upper bracket.

[0007] Furthermore, the upper bracket is provided with an adjusting support plate, the adjusting support plate is provided with an installation cavity, the lower bracket is provided with an adjusting support, the adjusting support is provided with a receiving groove extending along the X direction, and an adjusting slot is provided in the receiving groove. The adjusting handle has an adjusting end and a limiting end. The adjusting end of the adjusting handle is located in the installation cavity, and the limiting end of the adjusting handle is connected to the receiving groove in a drivable sliding manner along the receiving groove. The upper bracket and the lower bracket are slidably connected through the adjusting handle, and the adjusting end of the adjusting handle can be driven to move in a single degree of freedom along the Y direction. The limiting end of the adjusting handle moves accordingly to be inserted into the adjusting slot or away from the adjusting slot.

[0008] Furthermore, the upper support is also provided with a connecting plate, and the connecting plate is detachably equipped with a support slider. The support slider is slidably disposed in the receiving groove, and the upper support is slidably connected to the lower support through the support slider.

[0009] Furthermore, the adjusting slot is provided with multiple limiting holes. The limiting holes are funnel-shaped structures with radial dimensions gradually increasing from the inside to the outside along the Y direction. The limiting end of the adjusting handle is a funnel-shaped structure that conforms to the limiting holes. The limiting end of the adjusting handle can be manipulated to be inserted into any limiting hole to limit the relative sliding between the upper and lower supports.

[0010] Furthermore, the adjusting end of the adjusting handle is integrally formed with a limiting cap, and the radial gap between the limiting cap and the adjusting handle forms a limiting ring groove. The mounting cavity is a hollow columnar structure, and the adjusting handle is inserted into the mounting cavity. The adjusting handle is limited to the upper bracket by inserting the mounting cavity into the limiting ring groove.

[0011] Furthermore, the adjustment assembly also includes an adjustment link, an elastic clamping member, and a limiting member. The adjustment link passes through the adjustment slot and the adjustment handle sequentially from the inside to the outside. The limiting member includes a stop ring and a limiting clip. The stop ring is detachably installed on the adjustment link and located near the adjustment handle. The limiting clip is detachably installed on the adjustment link and located near the adjustment support. The limiting member limits the adjustment support and the adjustment handle in the axial direction of the adjustment link. The elastic clamping member is sleeved on the adjustment link and located between the adjustment handle and the limiting clip. The adjustment handle is pressed into the mounting cavity by the elastic clamping member.

[0012] Furthermore, there are two symmetrically arranged adjustment supports, and two adjustment handles, two adjustment plates, and two elastic clamping components are arranged correspondingly. The adjustment connecting rod is located between the two adjustment supports. The two ends of the adjustment connecting rod extend outward along the Y direction and pass through the adjustment slots and adjustment handles on both sides respectively. Two sets of limiting components are arranged accordingly. The two sets of limiting components respectively limit the adjustment supports and adjustment handles on both sides to the adjustment connecting rod simultaneously.

[0026] The reference numerals in the accompanying drawings include: upper bracket 1, lower bracket 2, adjusting support 3, adjusting handle 4, limit cap 401, limit end 402, limit ring groove 403, receiving groove 5, adjusting connecting rod 6, limit slot 601, bracket slider 7, guide block 701, adjusting support plate 8, connecting support plate 9, adjusting slot 10, limit hole 11, guide groove 12, elastic clamping part 13, stop ring 14, limit clip 15, extension bracket 16, bushing 17, bolt 18, washer 19, nut 20, set screw 21.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] The basic implementation examples are as follows: Figure 1-7As shown: An adjustable motorcycle windshield mounting bracket includes an upper bracket 1, a lower bracket 2, and an adjustment assembly. The upper bracket 1 is mounted on the lower bracket 2 in a controllable manner relative to the lower bracket 2 along the X direction. The adjustment assembly includes an adjustment handle 4 disposed on the upper bracket 1. The adjustment handle 4 can be driven to approach and connect to the lower bracket 2, so that the upper bracket 1 is locked and limited to the lower bracket 2; or, the adjustment handle 4 can be driven away from the lower bracket 2 to release the limitation on the upper bracket 1. Specifically, a linear motion pair structure, such as a slide rail and guide groove, is used between the upper bracket 1 and the lower bracket 2 to allow the upper bracket 1 to move freely in the X-axis direction, thus adjusting the windshield height. The adjustment handle 4 is used for manual operation to control the overall locking state of the mounting bracket. Specifically, a threaded knob or snap-fit ​​structure can be used, allowing the adjustment handle 4 to directly act on the lower bracket 2, eliminating the need for tools. Furthermore, by changing the spatial position of the adjustment handle 4 through external force, such as using an elastic reset mechanism or mechanical linkage device, friction or locking force is generated when the adjustment handle 4 contacts the lower bracket 2, thus fixing the upper bracket 1. Releasing the restriction on the upper bracket 1 is achieved by separating the adjustment handle 4 from the lower bracket 2, specifically by releasing the snap-fit ​​or releasing the friction constraint, allowing the upper bracket 1 to regain its sliding freedom. This embodiment achieves tool-free, quick adjustment of the motorcycle windshield bracket through the direct linkage design of the sliding structure and the adjustment handle 4. This method breaks through the rigid connection of traditional fixed brackets, utilizing the synergistic effect of a handle-driven locking mechanism and a sliding mechanism to expand the adjustment range and simplify the operation process, effectively solving the problems of limited adjustment and reliance on tools in existing technologies. Compared with fixed brackets, the windshield position can be flexibly adjusted according to the rider's height and usage scenario, thereby optimizing wind resistance protection. Through the above solution, this application achieves quick and convenient adjustment of the motorcycle front windshield bracket. Riders can adjust the windshield height at any time according to their height, sitting posture, or usage scenario, without stopping or using tools. The adjustment range is greatly increased, covering the entire posture range from upright riding to leaning forward for acceleration. The operation is simple and intuitive, improving the user experience. At the same time, the traditional threaded locking structure is eliminated, and a surface contact clamping method is adopted, reducing the requirements for operational precision and improving locking reliability and service life. This design effectively solves the problems of the inability to adjust traditional fixed brackets and the inconvenience of adjusting existing adjustable brackets, meeting the dynamic adjustment needs of different riding scenarios.

[0029] In this embodiment, the upper support 1 is provided with an adjusting support plate 8, which has a mounting cavity. The lower support 2 is provided with an adjusting support 3, which has a receiving groove 5 extending along the X direction. An adjusting slot 10 is formed in the receiving groove 5. The adjusting handle 4 has an adjusting end and a limiting end 402. The adjusting end of the adjusting handle 4 is located in the mounting cavity, and the limiting end 402 of the adjusting handle 4 is connected to the receiving groove 5 in a drivable sliding manner. The upper support 1 and the lower support 2 are slidably connected by the adjusting handle 4, and the adjusting end of the adjusting handle 4 can be driven to move with a single degree of freedom along the Y direction. The limiting end 402 of the adjusting handle 4 moves accordingly to be inserted into or away from the adjusting slot 10. Specifically, the mounting cavity of the adjusting support plate 8 is a hollow columnar structure used to accommodate the adjusting end of the adjusting handle 4. The receiving groove 5 of the adjusting support 3 extends along the X direction to form a continuous sliding track, and the adjusting slot 10 forms multiple positioning points in the receiving groove 5. The limiting end 402 of the adjusting handle 4 is configured with a geometry that matches the adjusting slot 10. The adjusting end and the limiting end 402 of the adjusting handle 4 are rigidly connected to form synchronous movement. During operation, the adjusting end of the adjusting handle 4 is inserted into the mounting cavity, and the limiting end 402 is inserted into the receiving slot 5. During operation, the adjusting handle 4 is pulled outward to disengage the limiting end 402 from the adjusting slot 10, and then the upper bracket 1 is slid along the X direction to the appropriate position. The adjusting handle 4 is then released to allow the limiting end 402 to re-insert into the corresponding adjusting slot 10 to complete the adjustment. The design of the adjusting handle 4 makes operation simple and intuitive, requiring no tools. The adjusting slot 10 provides a limit for adjustment to accommodate different rider needs. The limiting end 402 of the adjusting handle 4 cooperates with the adjusting slot 10 to reliably lock the relative positions of the upper and lower brackets 2, ensuring driving safety. The overall structure is simple and compact, easy to manufacture and maintain.

[0030] In this embodiment, the upper support 1 is further provided with a connecting support plate 9, and a support slider 7 is detachably mounted on the connecting support plate 9. The support slider 7 is slidably disposed in the receiving groove 5, and the upper support 1 is slidably connected to the lower support 2 through the support slider 7. Specifically, the support slider 7 is installed and fixed by bolts 18 and nuts 20. When fixing, the bolts 18 simultaneously pass through the receiving groove 5 (i.e., the adjusting support 3) and then connect with the nuts 20. This not only realizes the installation of the support slider 7 on the connecting support plate 9, but also further improves the connection reliability between the lower support 2 and the upper support 1. At the same time, a gasket 19 is provided on the contact surface between the nut 20 and the adjusting support 3, and a bushing 17 is provided at the contact surface between the bolt 18 and the support slider to improve the service life of the device. It should be noted that when using bolts 18 and nuts 20 for connection, they do not need to be fully tightened to avoid affecting the movement of the upper support 1 in the X direction. In order to prevent the connection from loosening, an anti-loosening nut 20 or a double nut 20 structure can be used. Thus, the detachable design of the support slider 7 facilitates maintenance and replacement and extends the service life of the support. The sliding structure is simple, reliable, and easy to operate, allowing for quick adjustment of the bracket height without tools, thus improving the user experience. At the same time, the sliding connection structure offers good stability, effectively preventing the upper bracket 1 from wobbling and ensuring driving safety.

[0031] In this embodiment, the adjusting slot 10 is provided with multiple limiting card holes 15 11. The limiting card holes 15 11 are trumpet-shaped structures with their radial dimensions gradually increasing from the inside to the outside along the Y direction. The limiting end 402 of the adjusting handle 4 is a trumpet-shaped structure adapted to the limiting card holes 15 11. The limiting end 402 of the adjusting handle 4 can be manipulated to be inserted into any of the limiting card holes 15 11 to limit the relative sliding between the upper support 1 and the lower support 2. Specifically, the trumpet-shaped structure design of the limiting card holes 15 11 makes its inner diameter gradually increase along the Y direction. This tapered structure can form a progressive fit with the limiting end 402 of the adjusting handle 4. The limiting end 402 of the adjusting handle 4 adopts a trumpet-shaped structure with the same taper. When the limiting end 402 is inserted into the limiting card hole 15 11, the two achieve self-centering and alignment through the contact of the tapered surfaces. As a preferred embodiment, the limiting card holes 15 11 can be arranged at equal intervals along the extension direction of the receiving slot 5 to form multiple fixed positions. The limiting end 402 of the adjusting handle 4 can selectively engage with the limiting clip 15 holes 11 at different positions via Y-axis movement, thereby achieving reliable locking of the upper bracket 1 at different positions. Thus, multi-position precise positioning is achieved through the flared engagement structure. The conical engagement between the limiting clip 15 holes 11 and the limiting end 402 effectively eliminates assembly gaps and improves connection rigidity. Compared with the traditional cylindrical hole engagement method, the flared structure has better guiding and self-locking properties, effectively preventing accidental loosening due to vibration during motorcycle operation. Simultaneously, this design makes adjustment operations smoother, requiring only a small axial force to lock or unlock, significantly improving adjustment convenience.

[0032] In this embodiment, the adjusting end of the adjusting handle 4 is integrally formed with a limiting cap 401. The radial gap between the limiting cap 401 and the adjusting handle 4 forms a limiting annular groove 403. The mounting cavity is a hollow cylindrical structure. The adjusting handle 4 passes through the mounting cavity and is limited in position on the upper bracket 1 by inserting the mounting cavity into the limiting annular groove 403. Specifically, the limiting cap 401 and the adjusting handle 4 are manufactured using an integral molding process to ensure structural strength and assembly accuracy. The width of the limiting annular groove 403 is slightly larger than the wall thickness of the mounting cavity, allowing the adjusting handle 4 to move axially within the mounting cavity while achieving radial limitation. The cylindrical structure of the mounting cavity is preferably a circular cross-section, with its inner diameter forming a clearance fit with the outer diameter of the adjusting handle 4. As a preferred embodiment, the diameter of the limiting cap 401 is larger than the opening diameter of the mounting cavity, forming a mechanical stop. The outer surface of the limiting cap 401 is provided with raised textures to facilitate operation. Thus, through the mating structure of the limiting cap 401 and the limiting annular groove 403, the precise positioning and reliable limitation of the adjusting handle 4 in the upper bracket 1 are achieved. The one-piece molded structure avoids assembly errors, and the columnar mounting cavity provides stable guidance. Compared with traditional solutions that require additional fasteners, this structure simplifies the assembly process, improves the movement accuracy of the adjusting handle 4, and ensures that there will be no skewing or loosening during frequent adjustments. Specifically, when the operator drives the adjusting handle 4 to move in the Y direction, the mating surface between the limiting ring groove 403 and the mounting cavity can effectively prevent the handle from shaking, ensuring that the limiting end 402 can be accurately aligned with the adjusting slot 10.

[0033] In this embodiment, the adjustment assembly further includes an adjustment link 6, an elastic clamping member 13, and a limiting member. The adjustment link 6 passes through the adjustment slot 10 and the adjustment handle 4 sequentially from the inside to the outside. The limiting member includes a stop ring 14 and a limiting clip 15. The stop ring 14 is detachably installed on the adjustment link 6 and located near the adjustment handle 4. The limiting clip 15 is detachably installed on the adjustment link 6 and located near the adjustment support 3. The limiting member limits the adjustment support 3 and the adjustment handle 4 in the axial direction of the adjustment link 6. The elastic clamping member 13 is sleeved on the adjustment link 6 and located between the adjustment handle 4 and the limiting clip 15. The adjustment handle 4 is pressed into the mounting cavity by the elastic clamping member 13. Specifically, the adjustment link 6 can be a metal rod or a high-strength plastic rod, and its diameter matches the inner diameter of the adjustment slot 10 and the adjustment handle 4 to ensure stability during insertion and not affect the relative movement of the upper and lower supports 2. The elastic clamping element 13 is preferably a helical spring, and its elastic coefficient is selected according to the clamping force required by the adjusting handle 4. The stop ring 14 is provided with a non-through channel for snap-fitting and is installed from the end of the adjusting handle 4. The limiting clip 15 is a C-type clip for easy disassembly and assembly. The adjusting handle 4 is also provided with a radially through channel through which the adjusting rod 6 passes, while accommodating the stop ring 14 and the elastic clamping element 13. In order to ensure that the elastic clamping element 13 can apply clamping force normally, a baffle structure is provided in the channel of the adjusting handle 4, or the channel of the adjusting handle 4 is set as a funnel-shaped structure that narrows from the outside to the inside, so that after the stop ring 14 and the elastic clamping element 13 are installed, they are held against the channel of the adjusting handle 4, preventing the adjusting handle 4 from being directly pulled out of the adjusting rod 6. Thus, through the cooperation of the adjusting rod 6, the elastic clamping element 13 and the limiting component, the relative position of the upper bracket 1 and the lower bracket 2 is stably limited. The elastic clamping member 13 continuously applies clamping force to ensure tight contact between the adjusting handle 4 and the mounting cavity, preventing accidental displacement due to vibration and further ensuring the reliability of the adjusting handle 4's positioning. The limiting component, through axial constraint, prevents the adjusting linkage 6 from axially shifting under force, thereby improving the overall structural reliability. Compared with existing technologies, this solution allows for adjustment without tools, and the limiting structure is more robust, adapting to vibrations and impacts under different riding conditions.

[0034] In this embodiment, there are two symmetrically arranged adjusting supports 3, two corresponding adjusting handles 4, two corresponding adjusting support plates 8, and two corresponding elastic pressing members 13. The adjusting link 6 is arranged at the position between the two adjusting supports 3. The two ends of the adjusting link 6 respectively extend outward along the Y direction and are respectively sequentially inserted through the adjusting slots 10 and the adjusting handles 4 on both sides. There are two corresponding sets of limiting components. The two sets of limiting components respectively limit the adjusting supports 3 and the adjusting handles on both sides to the adjusting link 6 synchronously. The two elastic pressing members 13 respectively press on the two adjusting handles. Specifically, the symmetrical arrangement of the adjusting supports 3 can improve the overall stability of the bracket and avoid deformation or loosening caused by uneven force on one side. The design that the adjusting link 6 penetrates through the adjusting supports 3 on both sides enables the adjusting mechanisms on both sides to act synchronously, ensuring that the upper bracket 1 moves horizontally during the adjustment process. The setting of the two sets of limiting components can respectively control the locking states on both sides and ensure uniform distribution of the locking force. The elastic pressing member 13 is a spring or other elastic element, which can provide continuous pressing force to ensure reliable cooperation between the adjusting handle 4 and the adjusting slot 10. The adjusting link 6 can adopt structures such as threaded rods and optical axes, and threads or slots are provided at both ends for installing the limiting components. The limiting components can be in the form of nuts 20, retaining rings, etc., which are convenient for adjustment and fixation. Thus, through the design of the double-adjusting mechanism with symmetrical arrangement, the problems of uneven force and asynchronous adjustment existing in the traditional single-side adjusting mechanism are solved. Among them, the through-type design of the adjusting link 6 realizes the linkage control of the mechanisms on both sides, ensuring the smoothness and reliability of the adjustment process. The two independent sets of limiting components and the elastic pressing members 13 can respectively control the locking states on both sides, which not only ensures uniform distribution of the locking force but also facilitates individual adjustment. Compared with the prior art, this solution significantly improves the stability and adjustment accuracy of the bracket, simplifies the operation process at the same time, and the height adjustment can be completed without tools, greatly enhancing the user experience.

[0035] In this embodiment, the connecting support plate 9 corresponds to two adjusting supports 3. Each adjusting support 3 has a receiving groove 5 with a guide groove 12 extending in the X direction. Each connecting plate has a bracket slider 7 integrally formed with a guide block 701. The two guide blocks 701 are slidably disposed within the two guide grooves 12. Specifically, the guide groove 12 is a through-slot structure extending in the X direction, used to accommodate the guide block 701 and restrict its movement direction. The guide block 701 is integrally formed with the bracket slider 7 and can be manufactured by casting, stamping, or machining. The shape of the guide block 701 matches the guide groove 12 to ensure smooth sliding. The cooperation between the guide groove 12 and the guide block 701 further restricts the movement direction of the bracket slider 7, preventing it from deflecting or jamming during sliding. As a preferred embodiment, a lubricating coating or ball bearing structure can be provided between the guide groove 12 and the guide block 701 to reduce frictional resistance and improve sliding smoothness. Therefore, by setting the guide groove 12 and the guide block 701, the sliding between the connecting support plate 9 and the adjusting support 3 can be ensured to be more stable and precise, avoiding the offset or jamming of the support slider 7 due to uneven force or vibration. Furthermore, the cooperation of the guide groove 12 and the guide block 701 can also improve the overall rigidity and stability of the support, making the relative sliding between the upper support 1 and the lower support 2 smoother, thereby improving the convenience of adjustment operation and user experience.

[0036] This embodiment also includes an extension bracket 16, which is installed on the lower bracket 2 and located at the X-direction end of the lower bracket 2. Both ends of the extension bracket 16 are detachably connected to two adjusting supports 3. The extension bracket 16 can be made of stamped metal sheet or cast aluminum alloy, and its ends are provided with threaded holes or snap-fit ​​structures to achieve a detachable connection with the adjusting supports 3. As a preferred embodiment, the extension bracket 16 is fixed to the adjusting supports 3 by set screws 21; the threaded connection facilitates disassembly and assembly and ensures a stable connection. The shape of the extension bracket 16 can be straight, L-shaped, or U-shaped to adapt to the needs of different installation scenarios. By adding the extension bracket 16, the installation space and load-bearing capacity of the lower bracket 2 can be effectively expanded. The extension bracket 16, installed at the X-direction end of the lower bracket 2, can form a stable connection with the adjusting supports 3, thereby enhancing the rigidity of the overall structure. Furthermore, the extension bracket 16 provides an installation base for subsequent installation of other functional components, such as lighting fixtures, navigation equipment, and other accessories. Therefore, this solution, while maintaining the original adjustable function of the bracket, expands its functionality through modular design, solving the problem of insufficient expandability of traditional brackets. Compared with existing technologies, this solution does not require modification to the main structure of the bracket; functional expansion can be achieved simply by adding an expansion bracket 16, offering advantages such as simple structure and convenient installation.

[0037] In this embodiment, the adjusting rod 6 is provided with multiple limiting slots 601, and the stop ring 14 and the limiting slots 601 are respectively snapped into the limiting slots 601 of the adjusting rod 6. Specifically, the limiting slots 601 are arranged at intervals along the axial direction of the adjusting rod 6 to form multiple fixed positions. The stop ring 14 and the limiting slots 15 can adopt an elastic snap-fit ​​structure, and achieve snap-fit ​​with the limiting slots 601 through radial elastic deformation. As a preferred embodiment, the limiting slots 601 are annular grooves, and the inner walls of the stop ring 14 and the limiting slots 15 are provided with protrusions that match the grooves. Furthermore, the spacing of the limiting slots 601 can be set to equidistant or non-equidistant arrangement according to the adjustment accuracy requirements. Thus, this technical solution achieves precise locking of the axial position of the adjusting rod 6 by setting a multi-level limiting slot structure 601. Among them, the stop ring 14 and the limiting slots 15 work together to ensure the stable connection of the adjusting components.

[0038] The specific implementation process is as follows:

[0039] When the operator pulls the adjusting end of the adjusting handle along the Y direction, the limiting end moves synchronously along the Y direction within the receiving groove. After the limiting end disengages from the current limiting hole, the upper bracket can slide freely along the X direction to the target position. When the adjusting handle is released, the elastic clamping element pushes the limiting end back into the corresponding limiting hole of the adjusting slot, forming a self-locking mechanism through the contact surface between the side wall of the limiting hole and the limiting end.
