TECHNICAL FIELD

[0001] The present application relates to the field of connectors, in particular to a multifunctional engineering connector and an engineering system thereof. BACKGROUND

[0002] As a core basic component in the field of building structure, equipment assembly, etc., the engineering connector needs to consider the stability and fixation of the connection part and the practical function in different scenarios, and the pressing block accessory, installation process and structural design of the connector directly determine the installation efficiency, operation and maintenance cost and service life of the whole project. In the actual application of the current engineering connector, there are still the following outstanding problems around the pressing block accessory, installation process and function adaptability. The existing engineering connector is exposed to outdoor or humid environment for a long time (such as building outer wall connection, outdoor equipment fixation), and needs to frequently deal with liquid erosion such as rain and dew, and the existing pressing block accessory is not specially designed for sealing and drainage demand: the fitting surface of the pressing block, the water guide groove and the connecting branch plate lacks special sealing structure and flow guide channel, liquid is easy to penetrate into the gap between the pressing block and the water guide groove, forming local water accumulation; long-term retention of water accumulation can accelerate the corrosion of the metal parts of the connector, leading to a decrease in connection strength, increasing the frequency and cost of later maintenance. The existing engineering connector does not design a reinforcing structure according to the stress characteristics of different scenarios (such as vibration caused by equipment operation, outdoor strong wind load, bearing pressure of building structure): part of the main body of the connector is not provided with reinforcing ribs, leading to weak stress in the middle part, which is easy to appear deformation such as middle part depression and edge warping when long-term bearing the self-weight of the connecting branch plate or external force; even at the installation stage, the deformation is caused by insufficient structural strength when tightening the fastener (such as bolt), at this time, the new connector needs to be replaced or corrected by pulling, hammering, etc., which not only reduces the structural strength of the connector itself, but also greatly prolongs the installation time, affecting the overall project progress. The installation of the existing engineering connector needs to follow the fixing sequence of "water guide groove → connecting branch plate → pressing block accessory → fastener", but the design defects of the key components lead to complicated processing and installation process: the nut of the connector is often fixed on the bracket by welding process, and each bracket needs to be welded with a nut separately, which is redundant and easy to cause deformation of the bracket due to welding temperature and precision error; at the same time, the nut lacks positioning and limiting structure after pressing, which is easy to deviate in subsequent operation, and when installing the bolt, the coaxiality of the bolt and the nut needs to be adjusted repeatedly, even if the electric tool is used to tighten, the tool is often idle or the bolt is loose due to misalignment, which significantly prolongs the installation time of a single set of connector and reduces the overall construction efficiency.

[0007] Preferably, the buckle cover plate is in a π-shaped structure, and elastic pads are arranged at the ends of the buckle cover plate extending outward on both sides, when the buckle cover plate is covered on the middle pressing cover plate, the elastic pads are extruded and sealed at the connecting position of the middle pressing cover plate.

[0008] Preferably, the bolt is fixed into the inside of the second connecting piece from the top of the support assembly, instead of the conventional installation mode from the side.

[0009] Preferably, the bracket assembly has a positioning groove for positioning the bolt, and the positioning groove can be aligned with the nut during installation.

[0010] Preferably, the nut can be pushed into the indwelling groove from the side of the bracket assembly along the position of the guide rib, the indwelling groove being formed by the sides of four elastic plates.

[0017] An engineering system comprising the multifunctional engineering connector described in any one of the above claims.

[0018] Beneficial effects: In existing technologies, screws are typically fixed into the second connector from the side of the bracket assembly. Due to the limited operating space on the side, installers find it difficult to accurately align the screws, resulting in low installation efficiency and a high risk of misalignment. This design adjusts the screw installation position to be fixed into the second connector from the top of the bracket assembly, significantly increasing the operating space. Installers can easily align the screws and fix them in place, significantly reducing installation difficulty and improving efficiency. The nut is pushed from the side of the bracket assembly along the guide rib into the groove formed by the surfaces of four elastic plates. The groove effectively limits the nut's position, while the inner wall of the groove restricts its rotation. Even when the elastic plates are deformed during bolt tightening, the nut's sides still abut against the inner wall of the groove, ensuring the nut does not rotate with the bolt. This eliminates the need for additional positioning by the installer, allowing for smooth bolt tightening and significantly improving installation efficiency and fixation effectiveness.

[0022] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0023] In one embodiment, please refer to the appendix to the specification. Figures 1-4As shown in Figures 9-10, the multifunctional engineering connector of the present invention includes multiple connecting support plates 1, a first connector 2 and a second connector 3 for supporting the connecting support plates 1, a cover plate 4 is provided at the connection of the connecting support plates 1, the cover plate 4 is used to seal the gap between the connecting support plates 1; a bracket assembly 6 is provided above the second connector 3, the bracket assembly 6 is used to connect the second connector 3, a medium pressure cover plate 5 is provided above the bracket assembly 6, the medium pressure cover plate 5 is used to press the connecting support plates 1, a bolt 7 is provided on the medium pressure cover plate 5, a nut 8 is installed on the bracket assembly 6, the bolt 7 and the nut 8 are connected by threads; the cover plate 4 covers the middle pressure cover plate 5.

[0024] This multifunctional connector is a new type of connector device that integrates efficient support, sealing protection, and convenient installation. Its core structure revolves around the stable fixing and efficient operation and maintenance of the connecting support plate. It is mainly composed of multiple connecting support plates 1, first connecting piece 2, second connecting piece 3, cover plate 4, medium pressure cover plate 5, bracket assembly 6, bolts 7, nuts 8, and purlins 10. All components work together to ensure the stable operation and efficient power generation of the connector. The first connecting piece 2 and the second connecting piece 3 are both water guide channels for drainage. The connecting support plate 1 is connected by multiple plates. The two ends of the connecting support plate 1 are provided with edge pressure square tubes 101, which are connected to the carport or wall. The connecting support plate 1 is existing technology and will not be described in detail here.

[0025] Please refer to the instruction manual appendix. Figures 1-8 As shown, the connecting support plate 1, as a core component of power generation, directly affects the overall power generation efficiency due to the stability of its arrangement and connection. To ensure reliable support for the connecting support plate 1, the support assembly 6 is positioned above the first connector 2 and the second connector 3. These components not only bear the weight of the connecting support plate 1 but also quickly drain rainwater during rainfall, preventing water accumulation from causing corrosion and damage to the connecting support plate 1 and the support components. The second connector 3, with its unique cross-sectional structure, possesses a larger drainage capacity and stronger structural strength compared to traditional drainage channels, enabling it to adapt to varying rainfall intensities and wind loads in different regions.

[0026] At the connection of the connecting support plate 1, a cover plate 4 is specially set. In order to prevent excessive water from flowing into the interior of the second connector 3, the drainage volume is reduced during the pressing of the connecting support plate 1, ensuring that the drainage volume of the second connector 3 is sufficient to completely drain the water that has entered its interior. By setting the cover plate 4 to seal the edge of the battery plate on the connecting support plate 1, the amount of water entering the interior of the second connector 3 is significantly reduced.

[0027] The cover plate 4 is made of aluminum alloy and its shape is perfectly matched with the connection gap of the connecting support plate 1. It can not only effectively seal the gap between the connecting support plates 1 to prevent rainwater, dust and other impurities from entering the gap and corroding the module frame and wiring terminals, but also play a certain buffering role, reducing the mutual squeezing damage of the connecting support plates 1 caused by thermal expansion and contraction or vibration under temperature changes or external forces, while improving the appearance of the entire array of connecting support plates 1.

[0028] Please refer to the instruction manual appendix. Figure 3 , 5 As shown, the middle pressure cover plate 5 includes a pressing block 51, with a bolt hole in the middle for the bolt 7 to pass through; pressure plates 52 are provided on both sides of the pressing block 51, the pressure plates 52 are used to fit against the frame of the connecting support plate 1, and multiple friction strips 53 are provided on the lower surface of the pressure plates 52; the pressure plates 52 have a U-shaped groove structure, and two inwardly protruding locking strips 54 are provided on the inner wall of the pressure plates 52, the locking strips 54 engage with the locking blocks on the cover plate 4, so that the cover plate 4 is fixed.

[0029] The intermediate pressure cover plate 5 is a key component for ensuring the stable fixation of the connecting support plate 1. Its structural design fully considers the reliability of fixation, ease of installation, and protection of the connecting support plate 1. It mainly consists of a clamping block 51, a pressure plate 52, a friction strip 53, and a retaining strip 54. Since the intermediate pressure cover plate 5 is placed on the connecting support plate 1, without the cooperation of the cover plate 4 and the intermediate pressure cover plate 5, water will overflow from both sides of the second connecting member 3 when there is too much water inside. The clamping block 51, as the main structure of the intermediate pressure cover plate 5, is integrally formed from high-strength aluminum alloy material, possessing excellent load-bearing capacity and corrosion resistance. In the center of the clamping block 51, a bolt hole matching the size of the bolt 7 is precisely opened. The inner wall of the bolt hole is precision machined to ensure the smooth passage of the bolt 7 and to prevent installation shaking caused by excessive gap between the bolt 7 and the hole wall. A pressure plate 52 is symmetrically arranged on both sides of the clamping block 51. The pressure plate 52 and the clamping block 51 are an integral structure, and their length is adapted to the width of the frame of the connecting support plate 1, ensuring that the pressure plate 52 can completely fit against the frame of the connecting support plate 1. To further improve the fixing stability between the pressure plate 52 and the frame of the connecting support plate 1, multiple friction strips 53 are evenly arranged on the lower surface of the pressure plate 52. These friction strips 53 are elongated protrusions, integrally formed with the pressure plate 52, and their surfaces have anti-slip textures. When the pressure plate 52 presses against the frame of the connecting support plate 1, the friction strips 53 can fit tightly against the surface of the frame of the connecting support plate 1, greatly increasing the friction between the two, effectively preventing the connecting support plate 1 from shifting under the action of external forces such as wind and earthquakes. At the same time, the elastic material can also prevent the pressure plate 52 from causing hard compression damage to the frame of the connecting support plate 1. Furthermore, the pressure plate 52 is designed with a U-shaped groove structure. This structure not only reduces the overall weight of the pressure plate 52 and the load on the support assembly 6, but also allows for convenient installation of functional structures on the inner wall of the U-shaped groove. Two inwardly protruding retaining strips 54 are symmetrically arranged on the inner wall of the U-shaped groove of the pressure plate 52. The retaining strips 54 are integrally formed with the pressure plate 52, and their protrusion height precisely matches the size of the retaining blocks on the cover plate 4. When the cover plate 4 is closed on top of the intermediate pressure cover plate 5, the retaining blocks on the cover plate 4 can perfectly engage with the retaining strips 54 on the inner wall of the pressure plate 52. Through the limiting effect of the retaining strips 54 on the retaining blocks, the cover plate 4 is firmly fixed, preventing it from falling off or shifting under the influence of external environmental factors, ensuring the long-term stability of the sealing effect.

[0030] Please refer to the instruction manual appendix. Figure 3 and 5 As shown in Figure 9, the bracket assembly 6 is provided with a through groove 61 and blocking blocks 62 on both sides of the through groove 61. The through groove 61 is used to install nuts 8. When the bolts 7 are tightened, the nuts 8 are stuck on the inner wall of the through groove 61. The bracket assembly 6 is provided with a positioning hole 67 in the middle, which is used for the bolts 7 to pass through. The bracket assembly 6 is provided with clamping plates 63 on both sides. The clamping plates 63 are engaged with the second connecting member 3. The clamping plates 63 are provided with mounting holes 64, and screws connected to the second connecting member 3 are installed in the mounting holes 64.

[0031] The support assembly 6 also includes guide ribs 65 disposed on the inner wall of the through groove 61. The nut 8 slides along the guide ribs 65 inside the through groove 61. An elastic piece 66 is disposed at the end of the guide rib 65. The elastic piece 66 has an arc-shaped structure. When the nut 8 slides from the guide rib 65 to the arc-shaped surface of the elastic piece 66, multiple elastic pieces 66 jointly support the nut 8. A support block 68 is disposed below the elastic piece 66. The end of the support block 68 is connected to the inner wall of the support assembly 6. The inclined side of the elastic piece 66 is parallel to the side of the nut 8, and two sides of the nut 8 are parallel to the inner wall of the through groove 61. Multiple elastic pieces 66 are used to abut against the nut 8 to position it. The axis of the nut 8 is coaxial with the axis of the bolt 7, making it easy for the bolt 7 to be screwed into the nut 8.

[0032] The bracket assembly 6 is the core transition component connecting the second connector 3 and the intermediate pressure cover plate 5. Its structural design revolves around convenient installation, precise positioning, and structural reinforcement. It mainly includes a through groove 61, a blocking block 62, a positioning hole 67, a clamping plate 63, a guide rib 65, an elastic sheet 66, and a support block 68. The various structures cooperate with each other to achieve a dual improvement in the installation efficiency and structural stability of the bracket assembly 6. In the middle of the bracket assembly 6, a through groove 61 is provided for installing the nut 8. The cross-sectional dimensions of the through groove 61 are adapted to the shape of the nut 8, ensuring that the nut 8 can be smoothly inserted into the through groove 61. At the same time, when the bolt 7 is tightened, the nut 8 can be tightly locked on the inner wall of the through groove 61, preventing the nut 8 from rotating with the bolt 7. The blocking block 62 is used to limit the position of the connecting support plate 1. A positioning hole 67 is also provided in the middle of the bracket assembly 6. The positioning hole 67 is coaxially aligned with the bolt hole on the clamping block 51. Its diameter is slightly larger than the diameter of the bolt 7, which can ensure that the bolt 7 can pass through smoothly and can also play a precise positioning role for the bolt 7, preventing the bolt 7 from shifting during installation and ensuring that the bolt 7 can accurately mate with the nut 8 in the through groove 61. Please refer to the accompanying drawings in the instruction manual. Figures 5-10 As shown, symmetrical locking plates 63 are arranged on both sides of the bracket assembly 6. The locking plates 63 are integrally formed with the bracket assembly 6, and their shape matches the groove structure of the second connector 3, enabling quick engagement and initial positioning of the bracket assembly 6 on the second connector 3. To further enhance the connection stability between the bracket assembly 6 and the second connector 3, mounting holes 64 are also provided on the locking plates 63. The positions of the mounting holes 64 precisely correspond to the preset mounting positions on the second connector 3. By installing screws in the mounting holes 64, the locking plates 63 and the second connector 3 are firmly connected, thereby achieving stable fixation of the bracket assembly 6 on the second connector 3. Compared with the existing technology where screws are fixed into the second connector 3 from the side of the bracket assembly 6, this design uses screws fixed into the interior of the second connector 3 from the top of the bracket assembly 6. This provides more operating space, eliminating the need for installers to operate in a confined side space, significantly reducing installation difficulty and improving installation efficiency. The cross-sectional opening of the second connector 3 is designed as a drainage groove, and its M-shaped cross-section forms three flow channels. Two water inlets are opened on the bracket assembly 6. The water inlets further improve the drainage effect of the bracket assembly 6. After rainwater falls on the surface of the solar panel of the connecting support plate 1, it flows along the edge of the solar panel into the drainage groove. Through the design of the drainage groove, it flows quickly to the end for drainage without any accumulation. At the same time, several water inlets on the front of the bracket assembly 6 can quickly drain the rainwater falling on the surface of the bracket assembly 6 into the second connector 3 below, avoiding the accumulation of rainwater on the bracket assembly 6. Moreover, the design of the water inlets not only achieves the drainage effect, but also realizes the lightweight design of the bracket assembly 6, reducing the overall weight of the bracket assembly 6.

[0033] The cooperation of the intermediate pressure cover plate 5, nut 8, bolt 7 and bracket assembly 6 achieves the effect of pressing and fixing the connecting support plate 1, making the locking process simpler. The intermediate pressure cover plate 5 also provides protection and waterproofing for the nut 8 and bolt 7.

[0034] This design, by setting through grooves 61, guide ribs 65 and elastic plates 66 on the bracket assembly 6, not only avoids structural defects caused by welding process, but also enhances the overall structural strength of the bracket assembly 6 through guide ribs 65, effectively preventing deformation of the bracket assembly 6 during installation and use, ensuring that the nut 8 is always in a precise positioning state, and ensuring reliable connection between bolt 7 and nut 8.

[0035] A positioning hole 67 is provided on the bracket assembly 6, and the nut 8 is precisely positioned by the guide rib 65 and the elastic plate 66, ensuring that the axis of the nut 8 and the axis of the bolt 7 remain coaxial. The installer only needs to insert the end of the bolt 7 into the corresponding positioning hole 67 to achieve precise docking between the bolt 7 and the nut 8, without the need to search for the nut position, which greatly simplifies the installation operation and improves the positioning accuracy.

[0036] To address the problems of difficult nut positioning and easy rotation in existing technologies, guide ribs 65 are provided on the inner wall of the through groove 61 of the bracket assembly 6. The guide ribs 65 are inclined to facilitate the sliding of the nut 8. The guide ribs 65 are integrally formed with the bracket assembly 6, and their height is adapted to the thickness of the nut 8. When installing the nut 8, it can slide smoothly along the guide ribs 65 inside the through groove 61. The guide ribs 65 serve two purposes: firstly, they provide a precise guiding path for the nut 8, preventing it from shifting during installation; secondly, they significantly enhance the overall structural strength of the bracket assembly 6, acting as a reinforcing rib and improving its resistance to bending and deformation. This effectively solves the problem of easy deformation during installation of the existing inverted U-shaped bracket 100. At the end of the guide rib 65, an elastic piece 66 is provided. The elastic piece 66 is made of a metal material with high elasticity and wear resistance and has an arc-shaped structure. The inclined side of the elastic piece 66 is parallel to the side of the nut 8. When the nut 8 slides along the guide rib 65 and passes over the elastic piece 66, the elastic piece 66 will undergo elastic deformation under the compression of the nut 8. After the nut 8 slides from the guide rib 65 to the arc-shaped surface of the elastic piece 66, the elastic piece 66 has an upward elastic force. At this time, multiple elastic pieces 66 together play a role in abutting and positioning the nut 8, ensuring that the axis of the nut 8 and the axis of the bolt 7 remain coaxial. It is easier for the bottom of the bolt 7 to contact, making it easier for the bolt 7 to be screwed into the nut. When the nut 8 is limited on the elastic piece 66, the upward stroke of the bolt 7 is shortened, and there is no sense of sticking during the upward movement of the bolt 7 after it is positioned. A shorter bolt 7 can be used to complete the tightening. During the tightening of the bolt 7, the nut 8 does not need to slowly move upward from the lowest end to the top of the through groove 61. Meanwhile, the inner wall of the through groove 61 restricts the rotation of the nut 8. Even if the elastic plate 66 is compressed and deformed during the tightening of the bolt 7, the two sides of the nut 8 will still abut against the inner wall of the through groove 61, preventing the nut 8 from rotating with the bolt 7. This eliminates the need for installers to use their fingers or tools to position the nut 8, completely solving the problem of the bolt 7 not being tightened due to the rotation of the nut 8, and significantly simplifying the installation process. When the bolt 7 is tightened, it will cause the clamping block 51 to move closer to the bracket assembly 6, further strengthening the fixation of the bracket assembly 6 and improving the stability of the overall structure.

[0037] Nut 8 is pushed from the side of bracket assembly 6 along guide rib 65 into the recess formed by the surfaces of four elastic plates 66. The recess effectively limits the nut 8, while the inner wall of through groove 61 restricts the rotation of nut 8. Even if the elastic plates 66 are compressed and deformed during the tightening of bolt 7, the two sides of nut 8 will still abut against the inner wall of through groove 61, ensuring that nut 8 will not rotate with bolt 7. Bolt 7 can be tightened smoothly without additional positioning by installers, significantly improving installation efficiency and fixing effect.

[0038] Please refer to the instruction manual appendix. Figure 10 As shown, the cover plate 4 has a π-shaped structure, and elastic pads are provided at the outwardly extending ends on both sides of the cover plate 4. When the cover plate 4 is closed on the medium pressure cover plate 5, the connection between the elastic pads and the medium pressure cover plate 5 is squeezed and sealed.

[0039] The two ends of the cover plate 4 extending outward are provided with elastic pads, which can be made of rubber. During the process of the cover plate 4 being snapped down, the elastic pads are squeezed and deformed at the contact point with the middle pressure cover plate 5, and the connection between the cover plate 4 and the middle pressure cover plate 5 is in a sealed state.

[0040] Please refer to the accompanying drawings in the instruction manual. Figure 10As shown, a purlin 10 is provided below the second connector 3. The purlin 10 is fixed to the bottom of the second connector 3 by two sets of screws to support the second connector 3.

[0041] Purlin 10, serving as the bottom support component of the second connector 3, is made of high-strength steel. Its cross-sectional structure is optimized, providing excellent load-bearing capacity and bending resistance. Purlin 10 is fixed to the bottom of the second connector 3 by two sets of symmetrically distributed screws, ensuring uniform stress distribution on the second connector 3 and preventing deformation of the second connector 3 or purlin 10 due to concentrated stress. Purlin 10 not only provides stable support for the second connector 3, evenly transferring the weight of the second connector 3 and the upper connecting support plate 1 to the foundation structure, but also adjusts the installation height and levelness of the second connector 3 to a certain extent, ensuring the installation accuracy of the entire connecting support plate 1 array and providing reliable assurance for the stability of the connecting support plate 1.

[0042] The landscape guidance ditch 9 can guide vines to climb or arrange decorative light strips according to the installation scene requirements, so as to realize the landscape decoration function of the connector.

[0043] On the other hand, the present invention also provides an engineering system including the multifunctional engineering connector described in any one of the above claims.

[0044] Installation process: Screws are inserted into the interior of the second connector 3 from the top of the bracket assembly 6, making installation easier compared to the side of the existing bracket 100; the existing bracket 100 has nuts 8 welded to the middle (see attached instruction manual). Figure 11As shown, the existing bracket 100 is prone to deformation during installation. A positioning hole 67 is provided on the bracket assembly 6 to facilitate the positioning of the bolt 7. During installation, the nut 8 is aligned with the positioning hole 67, avoiding the need to position the nut 8 during installation. It is only necessary to insert the end of the bolt 7 into the corresponding positioning hole 67. The nut 8 is pushed into the placement groove from the side of the bracket assembly 6 along the position of the guide rib 65. The placement groove is the place where the nut 8 is placed, formed by the surfaces of four elastic plates 66. The four sides of the nut 8 will fit against the corresponding elastic plates 66, thus limiting the nut 8 inside the placement groove. The guide rib 65 not only guides the nut 8 and strengthens the overall strength of the bracket, but also serves as an additional reinforcing rib. The groove supports the nut 8 while preventing the bolt 7 from moving upwards from the bottom of the through groove 61 after entering the nut 8. This shortens the stroke of the bolt 7, avoids wear on the inner wall of the through groove 61 caused by the nut moving inside during installation, and eliminates the need for additional finger or tool positioning of the nut 8. This prevents the nut 8 from rotating with the bolt 7 during tightening, thus making the installation process simpler. If this method is not used, when the nut 8 is at the bottom of the through groove 61, when the bolt 7 is rotated, the bolt 7 aligns with the nut 8. Due to the limiting effect of the through groove 61 on the nut 8, the rotation of the nut 8 is limited to a certain angle, and the nut 8 cannot rotate. When the bolt 7 is continued to be rotated, the corner of the nut 8 is pressed against the inner wall of the through groove 61. Due to the helical action of the bolt 7 and the limiting effect of the through groove 61, the nut 8 will move upward continuously during the tightening of the bolt 7. During the tightening of the bolt 7, there will be a noticeable resistance. The upward movement of the bolt 7 will also wear down the inner wall of the through groove 61. When this method is used, after the nut 8 enters the through groove 61, the through groove 61 will restrict the rotation of the nut 8. Even if the elastic piece 66 is compressed and deformed during the tightening of the bolt 7, neither end of the elastic piece 66 is connected to the through groove 61. When compressed by the nut 8, it bends and deforms downward. Due to the elastic piece 66 A support block 68 is provided below 6. The support block 68 can support the elastic sheet 66 under severe deformation and prevent the nut 8 from excessively squeezing the elastic sheet 66 and falling downwards from between the multiple elastic sheets 66. Since the two sides of the nut 8 abut against the inner wall of the through groove 61, the nut 8 will not rotate or move upwards during the tightening process, and will not cause wear to the inner wall of the through groove 61. This allows the bolt 7 to tighten the nut 8. During the tightening process of the nut 8, the clamping block 51 and the bracket assembly 6 will move closer to each other, thereby achieving the function of restricting the bracket assembly 6. When it is necessary to remove the nut 8, a tool can be inserted through the through groove 61 and pressed against the nut 8 to push the nut 8 onto the guide rib 65, so as to facilitate the removal of the nut 8. Alternatively, according to actual needs, a tool can be inserted through the inside of the positioning hole 67 to push the nut 8 onto the guide rib 65 and slide it downwards to be discharged from the inside of the through groove 61.
