Description

Technical Field

[0001] This application relates to the field of tooling technology, and more particularly to a fixing tool for a steering wheel. Background Technology

[0002] During the automobile manufacturing process, when tightening the steering wheel on the final assembly line, the worker stands outside the car, holding the tightening tool in one hand and tightening it against the large nut on the steering wheel while holding the steering wheel in place with the other hand. Due to excessive torque, the worker's strength with one hand is insufficient to hold the steering wheel in place, resulting in tightening failure or inability to tighten.

[0003] In related technologies, workers use their knees to brace the steering wheel to fix it in place when they get on the vehicle, or they stand outside the vehicle and use one hand to fix the steering wheel. This is inconvenient. Therefore, how to improve the convenience of fastening the steering wheel is a technical problem that urgently needs to be solved. Utility Model Content

[0004] This application provides a fixing fixture for a steering wheel, which improves the convenience of fastening the steering wheel.

[0005] To achieve the above objectives, the main technical solutions adopted in this application include:

[0006] In a first aspect, embodiments of this application provide a fixing fixture for a steering wheel, including a first rod portion, a first stop lever, a second stop lever, and a fixing bracket; both the first stop lever and the second stop lever are disposed on the first rod portion, and are spaced apart along the length direction of the first rod portion to abut against both sides of the steering wheel's stop arm; the fixing bracket is disposed on the first rod portion, and is located between the first stop lever and the second stop lever along the length direction of the first rod portion, and is used to fix a power tool for mounting the steering wheel to a vehicle.

[0007] According to the first aspect of the present application, the fixing fixture for the steering wheel has a first stop lever and a second stop lever respectively abutting against both sides of the steering wheel stop arm through a spaced interval. This provides a stable limit on the steering wheel from the lateral side, effectively preventing the steering wheel from shaking, shifting, or rotating during the tightening process, and providing a precise positional reference for subsequent tightening operations. At the same time, the fixing bracket is set at the first rod and located between the first stop lever and the second stop lever, which can reliably fix the power tool used to install the steering wheel. This allows the power tool to maintain a stable posture without additional manual support during the tightening process. This not only eliminates the tedious steps of manually fixing the steering wheel and power tool, but also avoids problems such as incomplete tightening or misalignment caused by manual operation deviations, greatly improving the convenience, efficiency, and installation accuracy of the steering wheel tightening operation.

[0008] Optionally, along the length of the first rod, the first stop and the second stop are located at the two ends of the first rod, and the fixed bracket is located in the middle area of ​​the first rod.

[0009] In the above solution, the first and second levers are located at both ends of the first lever, which is compatible with steering wheel arms of different widths. It can adapt to various vehicle models without frequent adjustment of the lever position, greatly improving the versatility of the tooling. The first and second levers at both ends of the first lever can form a clamping limit on the steering wheel arm, making the force points more dispersed and symmetrical, which can avoid excessive local force on the arm and deformation. At the same time, the force is balanced at both ends of the first lever, which can reduce the bending of the lever body caused by unilateral force and extend the service life of the tooling. The fixed bracket is located in the middle area, which is exactly within the stable limit range formed by the two levers. The power tool is fixed here, and the torque reaction force generated during operation can be evenly canceled by the two levers, effectively reducing tool vibration and deviation, ensuring that the bolts are accurately aligned with the mounting holes, and avoiding misalignment or uneven torque.

[0010] Optionally, the positions of both the first stop and the second stop are adjustable along the length of the first rod.

[0011] In the above solution, both the first and second levers are positionally adjustable along the length of the first lever, which significantly improves the adaptability and flexibility of the tooling. On the one hand, the distance and relative position of the two levers can be flexibly adjusted to accommodate the differences in the specifications of the steering wheel arm of different car models. This facilitates operation when the arm width and the mounting position of the arm on the steering wheel are different, avoiding tooling unusable or loosening due to mismatched arm specifications. This greatly expands the adaptability of the tooling to different car models. On the other hand, it allows for fine-tuning of the lever position based on the surrounding space of the steering wheel or the arm's own structure to avoid interference, ensuring that the lever can effectively contact the arm without damaging surrounding components, further improving ease of use.

[0012] Optionally, the fixing bracket includes a plate body and a first hoop, the plate body is fixed to the first rod, and the first hoop is disposed on the plate body and encloses a first limiting space for installing power tools.

[0013] In the above solution, the plate body can form a rigid connection with the first rod by increasing the contact area with the first rod. This not only prevents the fixed bracket from loosening or shifting when the power tool is working, providing a stable support foundation for the power tool, but also evenly transmits the reaction force of the power tool to the first rod, reducing deformation of the first rod caused by localized stress concentration and extending the overall service life of the tooling. The first limiting space enclosed by the first hoop can conform to the conventional shape of the power tool, such as a cylindrical body, forming a precise wrapping constraint. This ensures that the power tool is always aligned with the axis of the steering wheel fixing bolt after installation, preventing the bolt from being misaligned or not properly tightened due to tool tilting, and also prevents the power tool from accidentally falling off during high-frequency vibration, improving operational safety.

[0014] Optionally, the first hoop is constructed in an arc shape, and both ends of the first hoop are fixed to the plate body by the first fastener.

[0015] In the above solution, the arc-shaped structure can precisely fit the cylindrical body of common power tools. Compared with planar or zigzag constraints, it increases the contact area with the tool body, forming a tighter wrapping constraint. This effectively reduces high-frequency vibrations during power tool operation, prevents radial displacement of the tool during tightening, and ensures that the tool is always aligned with the axis of the steering wheel fixing bolt, improving tightening accuracy. It also allows for adjustment of the tightness of the arc-shaped clamp by adjusting the fastener's position, adapting to power tool bodies of different diameters. This eliminates the need to design separate clamps for single-size tools, broadening the tool compatibility range of the mounting bracket. Furthermore, the fastener connection is detachable. When the power tool needs maintenance, replacement, or tooling needs storage, the first clamp can be easily removed, facilitating tool access and disassembly for storage, reducing space occupancy.

[0016] Optionally, the first fastener passes through the first hoop, the plate body, and the first rod.

[0017] In the above solution, the fasteners penetrate through the first hoop, plate body, and first rod to form a rigid connection, rather than fixing the three separately. This completely eliminates the gaps between the components, preventing the fixing bracket from shifting or the first hoop from misaligning due to loosening of the components during the operation of the power tool. At the same time, the reaction force of the power tool can be directly transmitted to the entire tooling frame, dispersing the local stress and reducing the risk of deformation of the first rod or plate body. This significantly improves the constraint stability of the fixing bracket on the power tool, ensuring that the tool is always aligned with the axis of the steering wheel fixing bolt. On the other hand, the through-type fixing can force the precise alignment of the relative positions of the first hoop, plate body, and first rod, ensuring that the first limit space of the first hoop is always in the preset fastening position. This prevents the power tool from being unable to accurately align with the bolts due to misalignment of the three components, further ensuring the fastening accuracy of the steering wheel installation.

[0018] Optionally, the fixing bracket also includes a second hoop, which is disposed on the plate body and encloses a second limiting space for installing power tools.

[0019] In the above solution, the second limiting space can work together with the first limiting space to accommodate the power tool. It can provide a suitable limiting space for power tools of different specifications, improving the installation convenience for power wrenches and screwdrivers with large diameter differences, as well as tools with handles and pure body tools. It eliminates the need for frequent replacement or adjustment of individual clamps, greatly expanding the compatibility range of the fixing bracket with power tools. It can also fix different parts of the same power tool at two points, such as fixing the middle of the tool body and the grip section near the head. Compared with the single-point constraint of a single clamp, two-point limiting can more accurately restrict the radial wobble and circumferential rotation of the power tool. Especially when the power tool outputs high torque to tighten bolts, it can effectively reduce the offset of the power tool, ensuring that the tool is always aligned with the axis of the steering wheel fixing bolt, improving tightening accuracy and operational safety.

[0020] Optionally, along the first direction, the first hoop and the second hoop are opposite to each other and spaced apart, and the first direction is perpendicular to the thickness direction of the plate body.

[0021] In the above scheme, on the one hand, the first and second hoops are set opposite each other in a plane perpendicular to the thickness of the plate body, fixing the power tool at different positions. This avoids the tooling being too heavy and occupying the space around the steering wheel. This layout can firmly limit the radial sway and circumferential rotation of the tool through two-point spacing constraints without increasing the volume in the thickness direction of the plate body. It prevents the bolt from being twisted due to the tool being offset by a single point of force, greatly improving the fastening accuracy and operational safety. On the other hand, the spaced first and second hoops can be flexibly adapted according to the length of the power tool. For example, for long-bodied tools, both hoops can be used at the same time to achieve full-section stable constraint. For short-bodied tools, either hoop can be selected for individual fixing without changing the hoop or adjusting the tooling, thus broadening the compatibility range for power tools of different lengths.

[0022] Optionally, along the first direction, the projected area of ​​the first limiting space is smaller than the projected area of ​​the second limiting space.

[0023] The above solution can specifically improve the compatibility and stability of the fixed bracket for different sizes of power tools, while optimizing the ease of operation. On the one hand, the smaller first limiting space can accurately fit the body of small power tools, such as thin-barreled electric screwdrivers and mini torque wrenches. The tight fit reduces tool shaking and avoids positioning deviation caused by excessive space. The larger second limiting space is suitable for large power tools, such as thick-barreled impact wrenches and rechargeable wrenches with anti-slip rubber sleeves. This ensures that the tools can be installed smoothly, and the appropriate gap prevents difficulties in installation and disassembly or wear on the tool surface caused by excessive tightness. There is no need to frequently replace the clamps for tools of different sizes, which greatly expands the tool compatibility range of the fixture.

[0024] Optionally, at least one of the first rod, the first stop, the second stop, the plate body, the first hoop, and the second hoop is covered with a flexible material layer.

[0025] In the above solution, for the first and second gear levers that directly contact the steering wheel, the flexible material layer can replace the hard metal contact, preventing the gear levers from scratching the paint, plastic trim, or leather wrapping of the steering wheel when they abut against the steering wheel arm. For the first and second clamps that cooperate with the power tool, the flexible material layer can increase the friction with the tool body, reducing slippage and offset during operation. At the same time, by adapting the material elasticity to the slight dimensional errors or surface texture of the tool body, a tighter fit and constraint are formed, further improving the tool's fixation stability. Meanwhile, the flexible material layer can buffer the vibration and impact transmitted by the power tool, reduce collision and wear between metal parts, extend the tool's service life, and prevent the tool from damaging the vehicle's interior due to accidental bumps during handling or operation, protecting the components below the dashboard and around the steering column.

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0036] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used in the description of this application is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms "comprising" and "having," and any variations thereof, in the description, claims, and accompanying drawings of this application are intended to cover non-exclusive inclusion.

[0037] In this application, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.

[0038] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "attachment" 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 direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0039] In this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, in this application, the character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0040] In this application, "multiple" refers to two or more (including two), and similarly, "multiple groups" refers to two or more (including two), and "multiple pieces" refers to two or more (including two).

[0041] During the automobile manufacturing process, when tightening the steering wheel on the final assembly line, the worker stands outside the car, holding the tightening tool in one hand and pointing it at the large nut on the steering wheel, while using the other hand to hold the steering wheel in place to tighten it. Because the torque for tightening the steering wheel is too large, the strength of one hand is insufficient to hold the steering wheel in place, resulting in tightening failure / inability to tighten.

[0042] In related technologies, the methods of workers using their knees to hold the steering wheel in place or workers standing outside the vehicle using one hand to hold the steering wheel have the following disadvantages: 1. Workers working on the vehicle are prone to soiling interior parts, affecting product quality; 2. Workers standing outside the vehicle do not have enough strength with one hand to hold the steering wheel and fastening tools, posing a risk of injury to personnel or parts.

[0043] In view of this, to improve the convenience of fastening the steering wheel, this application proposes a fastening fixture for the steering wheel. A first stop lever 200 and a second stop lever 300 are spaced apart to abut against both sides of the steering wheel's retaining arm, respectively. A fixing bracket 400 is disposed on the first lever portion 100, along the length of the first lever portion 100, between the first stop lever 200 and the second stop lever 300. The fixing bracket 400 is used to fix the power tool used to install the steering wheel onto the vehicle. The first stop lever 200 and the second stop lever 300, spaced apart, abut against both sides of the steering wheel retaining arm, providing a stable lateral limit on the steering wheel and effectively preventing the steering wheel from shaking or shifting during the fastening process. The steering wheel can be rotated to ensure it remains in the preset installation position, providing a precise positional reference for subsequent tightening operations. Simultaneously, the fixing bracket 400 is positioned on the first lever 100 and between the first stop lever 200 and the second stop lever 300. This arrangement not only provides a stable support base based on the limiting structure of the two stop levers but also reliably secures the power tool used to install the steering wheel. This allows the power tool to maintain a stable posture without additional manual support during tightening, eliminating the tedious steps of manually fixing the steering wheel and power tool. It also avoids incomplete tightening or misalignment caused by manual operation deviations, significantly improving the convenience, efficiency, and installation accuracy of the steering wheel tightening operation.

[0044] When using the steering wheel fixing fixture, the operator will clamp the first stop lever 200 and the second stop lever 300 on the left and right sides of the stop arm in the direction of steering wheel rotation, respectively. When tightening, the steering wheel stop arm rotates in the opposite direction to the first stop lever 200 and the second stop lever 300 of the fixing fixture, which effectively solves the problem of the steering wheel following the rotation.

[0045] The fastening fixture for a steering wheel proposed in this application is described below with reference to the accompanying drawings.

[0046] Please refer to Figures 1-2According to an embodiment of the first aspect of this application, a fastening fixture for a steering wheel includes a first lever 100, a first stop lever 200, a second stop lever 300, and a fixed bracket 400.

[0047] Both the first stop lever 200 and the second stop lever 300 are located on the first lever portion 100. It can be understood that the first stop lever 200 and the second stop lever 300 can respectively abut against the steering wheel, thereby preventing the steering wheel from rotating. This reduces the possibility of synchronous rotation of the steering wheel during the tightening process, which could lead to installation misalignment or incomplete tightening. In other words, the abutting effect of the first stop lever 200 and the second stop lever 300 can directly limit the circumferential rotation of the steering wheel, eliminating the need for manual hand support. This frees up manpower and avoids positioning deviations caused by manual gripping, providing a stable benchmark for subsequent precise tightening.

[0048] Along the length of the first lever portion 100, the first stop lever 200 and the second stop lever 300 are spaced apart to abut against both sides of the steering wheel's stop arm, respectively. This arrangement allows for a suitable spacing based on the actual width of the steering wheel stop arm, ensuring that the first stop lever 200 and the second stop lever 300 can be precisely engaged on both sides of the stop arm. This avoids the stop arm not fitting due to insufficient spacing or wobbling due to excessive spacing, thus improving the tooling's adaptability to steering wheel stop arms of different specifications. At the same time, it helps to further reduce the possibility of the stop arm moving laterally or detaching from the stop lever constraint during the tightening process, further enhancing the circumferential limiting stability of the steering wheel, and also helps to prevent excessive force on one side from causing deformation of the stop arm or stop lever.

[0049] A fixing bracket 400 is disposed on the first rod portion 100. Along the length direction of the first rod portion 100, the fixing bracket 400 is located between the first stop lever 200 and the second stop lever 300. The fixing bracket 400 is used to fix the power tool for mounting the steering wheel to the vehicle.

[0050] Understandably, the fixed bracket 400, the first stop 200, and the second stop 300 are all located on the first rod portion 100, which helps to ensure the stability of the fixed bracket 400 itself and avoids shaking caused by the independent installation of the fixed bracket 400, thus helping to improve the fixing firmness of the power tool.

[0051] At the same time, it helps to offset the reaction force generated when the power tool is working (such as the torque backlash when tightening bolts) by the limiting structure of the stop bars on both sides, reducing the vibration and deviation of the power tool and avoiding problems such as bolt misalignment and uneven tightening torque caused by tool shaking.

[0052] Finally, fixed power tools directly solve the cumbersome process of holding the steering wheel with one hand and the power tool with the other in traditional operation. While freeing up both hands, the power tool always maintains the preset tightness angle and force, which greatly improves operating efficiency and reduces installation deviations caused by manual operation.

[0053] As an example, the power tool can be an electric wrench, a torque electric wrench, an electric screwdriver (impact type), or a cordless electric screwdriver, and this application does not limit it.

[0054] In other embodiments, please refer to Figure 1 and Figure 2 Along the length of the first rod portion 100, the first stop 200 and the second stop 300 are located at the two ends of the first rod portion 100, and the fixed bracket 400 is disposed in the middle area of ​​the first rod portion 100.

[0055] In the above solution, the first lever 200 and the second lever 300 are respectively located at both ends of the first lever 100, which can be compatible with steering wheel shift arms of different widths. They can be adapted to various vehicle models without frequent adjustment of the lever position, greatly improving the versatility of the tooling.

[0056] In terms of structural stability, the first stop 200 and the second stop 300 at both ends of the first rod 100 can form a clamping limit on the steering wheel arm, making the force points more dispersed and symmetrical, which can avoid excessive local force on the arm and deformation. At the same time, the force at both ends of the first rod 100 is balanced, which can reduce the bending of the rod caused by unilateral force and extend the service life of the tooling.

[0057] In terms of operational precision and convenience, the fixed bracket 400 is located in the middle area, which is exactly within the stable limit range formed by the two stop levers. When the power tool is fixed here, the torque reaction force generated during operation can be evenly offset by the stop levers at both ends, effectively reducing tool vibration and deviation, ensuring that the bolts are accurately aligned with the mounting holes, and avoiding misalignment or uneven torque.

[0058] In addition, the fixed bracket 400 in the middle position does not interfere with the stop levers at both ends, which not only provides ample operating space for power tools, but also makes it convenient for operators to observe the tightening process, further improving the efficiency and reliability of steering wheel installation.

[0059] In other embodiments, the first stop 200 and the second stop 300 are both adjustable in position along the length of the first rod portion 100. It is understood that the adjustable position of both the first stop 200 and the second stop 300 along the length of the first rod portion 100 significantly improves the adaptability and flexibility of the tooling.

[0060] On the one hand, the distance and relative position of the two levers can be flexibly adjusted according to the differences in the specifications of the steering wheel levers of different car models. This facilitates the operation when the width of the levers and the installation position of the levers on the steering wheel are different. It ensures that no matter the width or position of the levers, they can be accurately engaged on both sides of the levers to form a stable stop. This avoids the tooling being unusable or the limit being loose due to mismatched lever specifications. It greatly expands the applicability range of the tooling to different car models, eliminating the need to design special tooling for each car model.

[0061] On the other hand, in actual operation, the position of the shift lever can be finely adjusted according to the spatial environment around the steering wheel or the structure of the shift arm itself to avoid interference, ensuring that the shift lever can effectively contact the shift arm without damaging surrounding components. For example, it helps to reduce interference with obstacles such as steering column protrusions, wiring harnesses, reserved holes on the shift arm, and protruding components, further improving ease of use.

[0062] At the same time, it can also work with the position of the fixed bracket 400 to keep the relative positions of the first stop 200 and the second stop 300 with the fixed bracket 400 unchanged, which helps to counteract the reaction force when the power tool is working and further ensures the reliability of the fastening.

[0063] In addition, this adjustable design also facilitates the subsequent maintenance and reuse of the tooling. Even if the specifications of the shift lever change due to subsequent model updates, there is no need to replace the entire tooling. Only the position of the shift lever needs to be adjusted to continue using it, reducing usage costs and extending the service life of the tooling.

[0064] In other embodiments, please refer to Figure 1 and Figure 2 The fixed bracket 400 includes a plate body 410 and a first hoop 420. The plate body 410 is fixed to the first rod portion 100, and the first hoop 420 is disposed on the plate body 410 and encloses a first limiting space 421 for mounting power tools. It is understood that the plate body 410 can form a rigid connection with the first rod portion 100 by increasing the contact area with it. This not only prevents the fixed bracket 400 from loosening or shifting when the power tool is working (such as when tightening bolts and generating torque backlash), providing a stable support foundation for the power tool, but also evenly transmits the reaction force of the power tool to the first rod portion 100, reducing deformation of the first rod portion 100 caused by localized stress concentration and extending the overall service life of the tooling.

[0065] The first limiting space 421 enclosed by the first hoop 420 can conform to the conventional shape of the power tool, such as a cylindrical body, forming a precise wrapping constraint. This ensures that the power tool is always aligned with the axis of the steering wheel fixing bolt after installation, preventing the bolt from being misaligned or not properly tightened due to tool tilting. It also prevents the power tool from accidentally falling off during high-frequency vibration, thus improving operational safety.

[0066] Meanwhile, the hoop structure usually has a certain degree of flexibility in opening and closing, such as a detachable or elastic closing design. This application does not limit this, and the installation and removal of power tools can be completed quickly without complicated disassembly steps, which greatly simplifies the operation process and further adapts to the needs of efficient operation in the steering wheel installation scenario.

[0067] As an example, the plate body 410 is detachably connected to the first rod portion 100, including bolted connection, snap-fit ​​or hinged connection, which is not limited in this application.

[0068] In other embodiments, please refer to Figure 1 and Figure 2 The first hoop 420 has an arc-shaped structure, and both ends of the first hoop 420 are fixed to the plate body 410 by the first fastener 440. It is understandable that the arc-shaped structure can precisely fit the cylindrical body of common power tools, such as electric wrenches and screwdrivers. Compared to planar or zigzag constraints, it can increase the contact area with the tool body, forming a tighter wrapping limit, effectively reducing high-frequency vibrations during power tool operation, preventing radial displacement of the tool during tightening, ensuring that the tool is always aligned with the axis of the steering wheel fixing bolt, and improving tightening accuracy.

[0069] The two ends of the first hoop 420 are fixed to the plate body 410 by the first fastener 440. On the one hand, the size of the enclosed space of the arc hoop can be adjusted by adjusting the fastening position of the fastener, so as to adapt to the body of power tools of different diameters. There is no need to design a hoop separately for tools of a single size, thus expanding the tool compatibility range of the fixed bracket 400.

[0070] On the other hand, the fastener connection is detachable. When the power tool needs maintenance, replacement or the tooling needs to be stored, the first hoop 420 can be easily removed, which is convenient for tooling to be picked up and put away, and also facilitates the disassembly and storage of the tooling, reducing space occupation.

[0071] Meanwhile, this split-type fixing structure can reduce the processing difficulty. The arc-shaped hoop and the plate body 410 can be processed separately and then assembled without integral molding, which reduces the impact of manufacturing errors on the tool fixing accuracy. Furthermore, if the hoop wears or deforms later, only the hoop needs to be replaced, without replacing the entire fixing bracket 400, thus reducing maintenance costs.

[0072] In other embodiments, please refer to Figure 1 and Figure 2 The first fastener 440 passes through the first hoop 420, the plate body 410, and the first rod portion 100. It can be understood that the fastener passes through the first hoop 420, the plate body 410, and the first rod portion 100 to form a rigid connection, rather than fixing the three separately. This can completely eliminate the gaps between the components and prevent the fixed bracket 400 from shifting or the first hoop 420 from misaligning due to loosening between the components when the power tool is working.

[0073] At the same time, the reaction force of the power tool can be directly transmitted to the entire tooling frame, dispersing the local stress, reducing the risk of deformation of the first rod 100 or the plate body 410, greatly improving the constraint stability of the fixed bracket 400 on the power tool, and ensuring that the tool is always aligned with the axis of the steering wheel fixing bolt.

[0074] On the other hand, the through-type fixing can forcefully ensure that the relative positions of the first hoop 420, the plate body 410 and the first rod 100 are precisely aligned, so that the first limiting space 421 of the first hoop 420 is always in the preset fastening operation position, avoiding the inability of the power tool to accurately connect the bolts due to the misalignment of the three parts, and further ensuring the fastening accuracy of the steering wheel installation.

[0075] Furthermore, this design simplifies the assembly process, requiring only one fastener to secure the three components. This eliminates the need for separate steps to secure the plate body 410 to the first rod 100 and the first hoop 420 to the plate body 410, reducing assembly steps and positioning times and improving the overall assembly efficiency of the tooling. At the same time, the detachable fastener also facilitates subsequent maintenance. If the first hoop 420 wears, the plate body 410 deforms, or a hoop of a different specification needs to be replaced, only one fastener needs to be removed to disassemble the corresponding component without damaging the overall structure of the tooling, reducing maintenance costs and extending the tooling's reuse life.

[0076] In other embodiments, please refer to Figure 1 and Figure 2 The fixed bracket 400 also includes a second hoop 430, which is disposed on the plate body 410 and encloses a second limiting space 431 for installing power tools. It is understood that, on the one hand, the second limiting space 431 can work together with the first limiting space 421 to accommodate power tools, providing suitable limiting spaces for different specifications of power tools. This improves the ease of installation for power wrenches and screwdrivers with large diameter differences, as well as tools with handles and purely machine-type tools, eliminating the need for frequent replacement or adjustment of individual hoop rings and significantly expanding the compatibility range of the fixed bracket 400 with power tools.

[0077] Two-point fixation can also be applied to different parts of the same power tool, such as fixing the middle of the tool body and the grip section near the head. Compared with the single-point constraint of a single hoop, two-point limiting can more accurately restrict the radial wobble and circumferential rotation of the power tool. Especially when the power tool outputs high torque to tighten bolts, it can effectively reduce the offset of the power tool, ensure that the tool is always aligned with the axis of the steering wheel fixing bolt, and improve the tightening accuracy and operational safety.

[0078] On the other hand, the dual-hoop design also provides more flexibility for operating scenarios: if the space around the steering wheel is limited, a more suitable hoop can be selected according to the actual space; if a tool needs to be changed temporarily, the other hoop can be used as a spare work position, reducing the time for tool disassembly and adjustment and improving work efficiency; at the same time, the second hoop 430 and the first hoop 420 share the fixing base of the plate body 410, without the need to add an additional support structure to the first rod 100, which ensures structural compactness and avoids excessive tooling volume or operational interference caused by the addition of new parts, taking into account both practicality and ease of use.

[0079] In other embodiments, please refer to Figure 1 and Figure 2 Along the first direction X, the first hoop 420 and the second hoop 430 are opposite to each other and spaced apart, and the first direction X is perpendicular to the thickness direction of the plate body 410.

[0080] In the above scheme, on the one hand, the first hoop 420 and the second hoop 430 are arranged opposite each other in a plane perpendicular to the thickness of the plate body 410, and the power tool is fixed at different positions. Compared with the hoop arranged in a superimposed manner along the thickness direction, the tooling is not too heavy and occupies the space around the steering wheel. This layout can firmly limit the radial sway and circumferential rotation of the tool by two-point spacing constraint without increasing the volume of the plate body 410 in the thickness direction. It prevents the bolt from being twisted due to the tool being offset by a single point of force, and greatly improves the fastening accuracy and operation safety.

[0081] On the other hand, the first hoop 420 and the second hoop 430, which are set at intervals, can be flexibly adapted to the body length of the power tool. For example, for long-bodied tools, two hoops can be installed at the same time to achieve stable constraint throughout the entire length. For short-bodied tools, either hoop can be selected for individual fixing without replacing the hoop or adjusting the tooling, thus broadening the compatibility range with power tools of different lengths.

[0082] Meanwhile, when inserting the power tool, it can be aligned with the limiting space of the first hoop 420 and the second hoop 430 without adjusting the angle, simplifying the assembly and disassembly process. In addition, this layout can make full use of the planar space of the plate body 410, making the overall structure of the fixed bracket 400 lighter and more compact, adapting to the narrow operating environment around the steering wheel, and reducing the risk of interference with components such as the steering column and wiring harness.

[0083] In other embodiments, please refer to Figure 1 and Figure 2Along the first direction X, the projected area of ​​the first limiting space 421 is smaller than the projected area of ​​the second limiting space 431. This design can specifically improve the compatibility and stability of the fixed bracket 400 with different specifications of power tools, while optimizing the ease of operation. On the one hand, the difference in projected area can improve the compatibility with power tools of different diameters. The smaller first limiting space 421 can accurately fit the body of small power tools, such as thin-handled electric screwdrivers and miniature torque wrenches. The tight fit reduces tool shaking and avoids positioning deviation caused by excessive space.

[0084] The larger second limiting space 431 is suitable for large power tools, such as thick-bar impact wrenches and rechargeable wrenches with anti-slip rubber sleeves. It ensures that the tools can be installed smoothly, and the appropriate gap is reserved to avoid difficulties in installation and disassembly or wear on the tool surface caused by excessive tightness. There is no need to frequently replace the clamp for tools of different sizes, which greatly expands the tool compatibility range of the tooling.

[0085] On the other hand, this differentiated design can guide users to quickly match tools with the available space, reducing trial and error time. Especially in assembly line operations or scenarios where multiple tools are used alternately, users can directly select the corresponding space based on the size of the tool, thus improving operational efficiency.

[0086] In other embodiments, at least one of the first lever portion 100, the first stop lever 200, the second stop lever 300, the plate body 410, the first hoop 420, and the second hoop 430 is covered with a flexible material layer. It is understood that for the first stop lever 200 and the second stop lever 300, which directly contact the steering wheel, the flexible material layer can replace the hard metal contact, preventing the stop lever from scratching the paint, plastic trim, or leather wrapping of the steering wheel surface when it abuts against the steering wheel arm. This is especially beneficial for the refined interiors of high-end vehicles, effectively protecting the integrity of the workpiece's appearance.

[0087] For the first hoop 420 and the second hoop 430 that cooperate with the power tool, the flexible material layer can increase the friction with the tool body, reduce slippage and offset when the power tool is working, and at the same time, by adapting the material elasticity to the slight dimensional errors or surface texture of the tool body, a tighter fit constraint is formed, further improving the tool's fixation stability.

[0088] For the main components of the tooling, such as the first rod 100 and the plate body 410, the flexible material layer can buffer the vibration and impact transmitted by the power tool, reduce the collision and wear between metal parts, extend the service life of the tooling, and at the same time prevent the tooling from being damaged by accidental bumps during handling or operation, and protect the components below the dashboard and around the steering column.

[0089] In addition, the flexible material layer can improve operational safety by wrapping the metal edges or corners of the tooling, preventing operators from being scratched by sharp parts when adjusting the tooling position, thus combining practicality and human-centered design.

[0090] As an example, the flexible material layer includes at least one of silicone, rubber, ethylene-vinyl acetate copolymer, polyurethane foam, fleece and polytetrafluoroethylene, and this application does not limit this.
