Description

Technical Field

[0001] This invention relates to the field of wind turbine foundation construction technology, specifically to a wind turbine foundation pouring formwork system that is easy to assemble and disassemble for wind turbine foundation construction. Background Technology

[0002] The wind turbine foundation is the fixed end of the wind turbine generator set and an important component to ensure that the wind turbine can generate electricity normally. The wind turbine foundation is generally made of reinforced concrete and is designed in different forms according to the local geological conditions during actual construction. It is mainly constructed in accordance with the load of the tower and the climate environment where the unit is located, combined with the construction specifications for high-rise buildings.

[0003] Because wind turbine foundations are made of poured concrete, specific formwork components are typically installed before pouring. Existing wind turbine foundations are generally cylindrical structures, so the formwork used is mostly curved to form a circular formwork system. However, correspondingly, most existing formwork uses bolts and nuts for installation, making manual assembly and disassembly extremely time-consuming. Furthermore, since the formwork pieces need to be aligned and are not directly connected, installation requires manual handling of the formwork pieces, and even simple vertical or horizontal alignment requires multiple people to assist. This significant waste of manpower greatly impacts installation efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a wind turbine foundation casting formwork system that is easy to assemble and disassemble, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a wind turbine foundation casting template system that is easy to assemble and disassemble, comprising a lower template and an upper template, both of which are composed of several templates. Each template has an end plate at its top and bottom. A rail is installed at the middle of the outer surface of the template, with the rail protruding outwards. An outer guide groove is provided on the inner surface of the template, which engages with the rail for limiting. An inner guide groove is provided inside the template on the inner side of the outer guide groove. An elastic connection mechanism is installed between the inner guide groove of any template and the side of an adjacent template. The elastic connection mechanism is used to achieve a limiting connection between two adjacent templates. A first screw is installed between the two templates outside the elastic connection mechanism. A track robot is mounted on the surface of the track. A sleeve is mounted on the top of the track robot. Telescopic mechanisms are mounted on both sides of the sleeve, and rotating sleeve mechanisms are mounted on the sides of the telescopic mechanisms. The rotating sleeve mechanisms are engaged with the first screw. Both the surface of the end plate and the surface of the track are provided with screw holes, and the lower module is provided with at least two sets of templates from top to bottom. The screw holes of the upper and lower templates are aligned with each other. A connecting rod is installed inside the screw hole, and a sliding sleeve mechanism for connection and limitation is installed between the top of the connecting rod and the lower part of the upper module.

[0006] Preferably, the elastic connection mechanism includes an elastic element, a guide rod, a magnetic block, a top block, and a connecting block. A top block is installed at the end of the inner guide groove of any template, and a connecting block is installed on the side surface of the template adjacent to the top block. The guide rod is movably limited inside the inner guide groove, and a magnetic block is installed on the surface of the guide rod. An elastic element is installed between the magnetic block and the connecting block.

[0007] Preferably, the telescopic mechanism includes a first electric push rod and a sliding rod. Both sides of the sleeve column are provided with openings, and the sliding rod is movably sleeved inside the openings. The first electric push rod is installed between the end of the sliding rod and the sleeve column.

[0008] Preferably, the rotating sleeve mechanism includes a second electric push rod, a ranging component, and a rotating screw sleeve. The second electric push rod is installed at the bottom of the slide rod, the ranging component is installed on the surface of the second electric push rod, and the rotating screw sleeve is installed at the end of the output rod of the second electric push rod.

[0009] Preferably, the surface of the rotating screw sleeve is provided with a square hole, and the square hole is arranged facing the first screw. A rotary motor is installed between the rotating screw sleeve and the output rod end of the second electric push rod, and a rotating seat is installed between the top of the track robot and the sleeve column.

[0010] Preferably, the surface of the connecting rod is provided with several sets of threaded areas, and connecting rings are installed on the top end of the connecting rod and the lower surface of the upper module.

[0011] Preferably, the sliding sleeve mechanism includes a telescopic rod and a bearing member. Both ends of the telescopic rod are equipped with bearing members, and the two bearing members are respectively connected to the connecting ring of the connecting rod and the lower connecting ring of the upper module through pins.

[0012] Preferably, the telescopic rod is formed by connecting an outer rod and an inner rod from the outside to the inside. The bottom surface of the outer rod and the top surface of the inner rod are respectively provided with several screw holes and one screw hole, and a positioning screw is provided inside the screw hole.

[0013] Preferably, the end plate surface on one side of the screw hole is provided with an insertion hole, the insertion holes of the end plates of the two templates at the upper and lower positions are aligned with each other, and the second screw is installed inside the insertion hole together.

[0014] Preferably, the inner surface of any one of the templates contacts the outer surface of another template and forms a stacked effect of the two templates, and the track is limited and assembled inside the outer guide groove. A connecting block is installed on the upper part of one side surface of the upper template, and a magnetic block is magnetically attracted to the end of the track of the upper template. A guide rod is installed on the surface of the magnetic block, and an elastic element is installed between the magnetic block and the connecting block.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This wind turbine foundation casting template system, which facilitates assembly and disassembly, features a structurally designed individual template. With the cooperation of external guide channels, internal guide channels, and tracks, it forms a continuous circular track structure throughout the entire wind turbine foundation casting template installation process. This allows a track-guided robot to move along the track, enabling the robot to assemble and disassemble the first screws on the left and right templates. This avoids the tedious process of manual assembly and disassembly. During subsequent stacking, the track allows for insertion into the external guide channels, creating a limiting stack between the upper and lower templates. During subsequent unfolding, the templates slide to one side using the track, achieving an arc-shaped unfolding effect under a uniform force, facilitating subsequent connection and installation. It also provides unified initial positioning for the upper and lower templates, facilitating the installation of the second screw. The overall assembly and disassembly process achieves the connection between the upper and lower modules. The combination of robotic and manual assistance in assembly and disassembly significantly improves efficiency and facilitates storage.

[0016] 2. This wind turbine foundation casting formwork system, which is easy to assemble and disassemble, uses screw holes. When the upper and lower formworks are assembled, the screw holes are aligned vertically. This allows for easy connection of a single connecting rod to multiple formworks in a vertically aligned manner. The connecting rod is used as a structural reinforcement. The connecting rod is directly inserted into the soil below to limit the bottom of the formwork. At the same time, the connecting ring on the connecting rod facilitates the installation of the telescopic rod. When the telescopic rod is in action, it facilitates the transmission of the tension of the upper module from top to bottom through the connecting rod. This allows each formwork to be subjected to torque in multiple directions, avoiding adverse phenomena such as concentrated force or tilted force that could lead to instability of the lower module structure. This achieves the multi-functional use of the connecting rod.

[0017] 3. This wind turbine foundation casting formwork system, which facilitates assembly and disassembly, utilizes the structural effect of the track limiting the upper formwork to move towards the top block along the outer guide channel when the formwork is stacked or about to be unfolded. This facilitates the smooth insertion of the guide rod into the inner guide channel. When the upper and lower formworks are separated, the guide rod and the inner guide channel limit the connection between the two formworks. Even after separation, the upper formwork can rebound partially with the help of elastic components, facilitating the mating of the two formwork surfaces. This eliminates the need for manual assistance on one side and facilitates the installation operation after mating. Furthermore, the inner and outer guide channels are relatively small in size and the structure is complex, making it difficult for concrete to enter the channel. During subsequent formwork disassembly, a pry bar can be inserted into the channel to apply force to the formwork, thus facilitating the disassembly process.

[0018] 4. This wind turbine foundation casting formwork system, which is easy to assemble and disassemble, has a telescopic function through the telescopic rod, which forms a connection between the upper and lower formwork. Even when the lower formwork lacks a limiting torque in the direction of the center, the tension of the telescopic rod can make the lower formwork bear the force in the direction of the center. This can prevent the lower formwork from being squeezed outward by concrete during subsequent pouring and avoid adverse phenomena such as expansion. When not in use, the telescopic rod can be extended or retracted, and the actual size is small and easy to store. Attached Figure Description

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

They are used only for the convenience of describing this invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] like Figures 1 to 8As shown, the wind turbine foundation casting formwork system of this embodiment, which is easy to assemble and disassemble, includes a lower formwork 1 and an upper formwork 4. Both the upper formwork 1 and the lower formwork 4 are composed of several templates 32. Both the lower formwork 1 and the upper formwork 4 have a near-circular structure, which is conducive to forming a cylindrical wind turbine foundation after concrete pouring. The actual size of the lower formwork 1 is larger than that of the upper formwork 4. The upper formwork 4 is used for the construction of the concrete base at the bottom of the wind turbine beams and columns. The overall structure of the template 32 is arc-shaped, which is conducive to forming a circular module. End plates are provided at the top and bottom of the template 32. 19. End plate 19 serves as support and connects the upper and lower parts. A track 10 is installed at the middle of the outer surface of template 32. Unlike the ribs of template 32 itself, track 10 is convex and has a T-shaped cross-section. An outer guide groove 12 is provided on the inner surface of template 32. The outer guide groove 12 is matched with the track 10 for limiting. It should be noted that the depth and actual width of the outer guide groove 12 are moderate to prevent large particles of concrete from entering during subsequent pouring. After actual pouring, the poured cylindrical surface and the outer guide groove are aligned. There is a large gap between the templates 12 and 12. The template 32 can be pried open through the outer guide groove 12 with the help of an external pry bar, which is conducive to subsequent normal disassembly and reuse. The track 10 itself can be limited by the outer guide groove 12. Under force, the track 10 can move within the outer guide groove 12. The template 32 inside the outer guide groove 12 is provided with an inner guide groove 13. The width of the inner guide groove 13 is smaller than that of the outer guide groove 12. Thus, in the side view, both the inner guide groove 13 and the outer guide groove 12 are T-shaped grooves. An elastic connection mechanism is installed between the inner guide groove 13 of any template 32 and the side of the adjacent template 32. The elastic connection mechanism is used to realize the limiting connection of two adjacent templates 32 and can be used for auxiliary connection in the disassembly and assembly of templates 32. A second screw 20 is installed between the two templates 32 outside the elastic connection mechanism. That is, the two templates 32 in the left and right positions are connected by a first screw 6. The first screw 6 is actually a combination of bolt and nut. Therefore, corresponding through holes need to be set between the sides of the two templates 32 for use. A track robot 22 is mounted on the surface of track 10. Since track 10 is a T-shaped track, the bottom of track robot 22 forms a limiting form with track 10. Its bottom is equipped with a walking mechanism and is loaded with conventional mobile power supply, processor and other components. It can walk on track 10. When multiple templates 32 are combined together, the tracks 10 can be connected front and back, which is conducive to track robot 22 normally circling the upper module 4 or the lower module 1 to complete walking and other operations. The top of track robot 22 is equipped with a sleeve post 21. The left and right surfaces of sleeve post 21 are open and the inner cavity is hollow. The two sides of sleeve post 21 are equipped with telescopic mechanisms, and the sides of telescopic mechanisms are equipped with rotating sleeve mechanisms. The rotating sleeve mechanism is engaged with the first screw 6, which can be disassembled and assembled. Both the surface of the end plate 19 and the surface of the track 10 are provided with screw holes 11. The screw holes 11 are arranged vertically and have internal threads. The lower module 1 is provided with at least two sets of templates 32 from top to bottom. Because the concrete foundation pit of the wind turbine foundation used by the lower module 1 is deep or high, multiple sets of templates 32 are required. The screw holes 11 of the upper and lower templates 32 are aligned with each other. A connecting rod 5 is installed inside the screw hole 11. The actual length of the connecting rod 5 is large and can be directly inserted into the different screw holes 11 aligned below from top to bottom, thus forming a vertical and horizontal limiting effect for each template 32. In the initial assembly of the template 32, while forming vertical and horizontal limiting, it can prevent the templates 32 from moving in the left and right directions, thus forming a preliminary limiting effect, which is convenient for subsequent assembly of bolts, nuts and other components. A sliding sleeve mechanism for connecting and limiting is installed between the top of the connecting rod 5 and the lower part of the upper module 4, forming a connection effect between the upper module 4 and the lower module 1.

[0024] Specifically, the elastic connection mechanism includes an elastic element 14, a guide rod 15, a magnetic block 16, a top block 17, and a connecting block 18. A top block 17 is installed at the end of the inner guide groove 13 of any template 32. The top block 17 effectively blocks the inner end of the inner guide groove 13, allowing the inner guide groove 13 to be used as a groove structure with only one side opening. A connecting block 18 is installed on the side surface of the adjacent template 32 near the top block 17. That is, when two adjacent templates 32 are used together, a connecting block 18 is installed on the side surface of the template 32. The connecting block 18 is positioned close to the top block 17 during use. The guide rod 15 is movably limited inside the inner guide groove 13, and its surface is equipped with... There is a magnetic block 16, and an elastic element 14 is installed between the magnetic block 16 and the connecting block 18. Under normal use, because the entire inner guide groove 13 is a T-shaped groove structure, the two ends of the guide rod 15 can be limited in the inner guide groove 13. The magnetic block 16 itself is a flat structure and is small in size. Under the limiting action of the guide rod 15, the magnetic block 16 can pass through the inner guide groove 13. The elastic element 14 itself is an elastic rope structure with good physical strength. The connection effect between the magnetic block 16 and the connecting block 18 can be tested. When the two templates 32 are adjacent and assembled with each other, the elastic element 14 can generate a limiting elastic force, so that the inner sides of the two adjacent templates 32 are limited and connected, and a preliminary limiting effect is achieved again, which facilitates the subsequent assembly between adjacent templates 32.

[0025] Furthermore, the telescopic mechanism includes a first electric push rod 23 and a slide rod 25. Both sides of the sleeve column 21 are provided with openings, and the slide rod 25 is movably sleeved inside the openings. The slide rod 25 can enter the inner cavity of the sleeve column 21, thereby completing the telescopic storage operation. The first electric push rod 23 is installed between the end of the slide rod 25 and the sleeve column 21. The first electric push rod 23 is an electric telescopic push rod, which can be programmed to control the motor to perform telescopic movement. The fixed part is installed on the top of the sleeve column 21, and its output rod part is hinged to the end surface of the slide rod 25. When the first electric push rod 23 telescopically extends or retracts, it can drive the slide rod 25 to perform inward and outward telescopic movement.

[0026] Furthermore, the rotating sleeve mechanism includes a second electric push rod 24, a ranging component 26, and a rotating screw sleeve 27. The second electric push rod 24 is installed at the bottom of the slide rod 25 and offset to one side so as not to affect the telescopic movement of the slide rod 25. The models of the second electric push rod 24 and the first electric push rod 23 are selected according to the actual size of the template 32 or the position of the first screw 6. The second electric push rod 24 telescopically moves in the vertical direction. The ranging component 26 is installed on the surface of the second electric push rod 24. The ranging component 26 can be a laser ranging device, which can detect the actual position of the first screw 6. The rotating screw sleeve 27 is installed at the end of the output rod of the second electric push rod 24. When the actual position of the first screw 6 is detected by the ranging component 26, the actual positions of the first electric push rod 23 and even the second electric push rod 24 are adjusted to ensure that the rotating screw sleeve 27 is properly sleeved on the first screw 6.

[0027] Furthermore, the surface of the rotating sleeve 27 is provided with a square hole, which faces the first screw 6. Therefore, when the entire track robot 22 is in use, the combination of all the first screws 6 needs to be uniformly designed. For example, the nut is fixedly welded to the template 32, and the square head of the bolt faces the square hole. The square hole directly causes the entire rotating sleeve 27 to be sleeved on the bolt head. A rotary motor is installed between the rotating sleeve 27 and the output rod end of the second electric push rod 24. After the rotary motor is started, it directly rotates the rotating sleeve 27, thereby realizing the rotation of the bolt. While rotating, the track robot 22 moves slightly backward to meet the disassembly requirements. A rotating seat is installed between the top of the track robot 22 and the sleeve post 21. The rotating seat is equipped with a motor, which allows the sleeve post 21 and even the entire rotating sleeve mechanism on it to have a certain rotation, realizing the angle adjustment function and facilitating the sleeve of the bolt head.

[0028] Furthermore, the surface of the connecting rod 5 is provided with several sets of threaded areas 7, which are actually used in conjunction with the screw holes 11. When the entire connecting rod 5 is uniformly inserted into several templates 32 aligned below, the connecting rod 5 needs to rotate in stages to facilitate the threaded connection between the threaded areas 7 and the screw holes 11 in each area, thus meeting the requirements for fixed connection. In addition, the top of the connecting rod 5 and the lower surface of the upper module 4 are both equipped with connecting rings 8. The connecting rings 8 are large in size and have high structural strength.

[0029] Furthermore, the sliding sleeve mechanism includes a telescopic rod 2 and a bearing 3. Both ends of the telescopic rod 2 are equipped with bearings 3. The bearing 3 is similar to a bearing component and has a U-shaped structure. The two bearings 3 are respectively connected to the connecting ring 8 of the connecting rod 5 and the lower connecting ring 8 of the upper module 4 through pins. In actual installation, the bearing 3 is sleeved on both sides of a single connecting ring 8. With pin holes provided on the surface of the bearing 3, the pin is directly inserted to improve the connection between the bearing 3 and the connecting ring 8.

[0030] Furthermore, the telescopic rod 2 is formed by connecting an outer rod 29 and an inner rod 28 from the outside in. The bottom surface of the outer rod 29 and the top surface of the inner rod 28 are respectively provided with several screw holes 30 and one screw hole 30. That is, several screw holes 30 can be evenly distributed on the surface of the outer rod 29, while the top part of the inner rod 28 is provided with one screw hole 30. The screw hole 30 is provided with a positioning screw 31. In actual use, since the length of the telescopic rod 2 needs to be set according to the construction requirements, the inner rod 28 moves inward and outward relative to the outer rod 29. After adjusting the actual length of the entire telescopic rod 2, the screw hole 30 at the top of the inner rod 28 is aligned with the screw hole 30 at the bottom of the adjacent outer rod 29, and then the positioning screw 31 is installed to achieve the overall fixing effect of the telescopic rod 2.

[0031] Furthermore, the end plate 19 on one side of the screw hole 11 is provided with an insertion hole 9. The insertion holes 9 of the end plates 19 of the two templates 32 at the upper and lower positions are aligned with each other. When installing the two templates 32 at the upper and lower positions, the end plates 19 need to be aligned. Thus, with the insertion holes 9 aligned, it is convenient to fix and install the upper and lower templates 32. The second screw 20 is installed inside the insertion hole 9. The first screw 6 and the second screw 20 have the same structure but different actual installation positions. After the entire track robot 22 disassembles the first screw 6, the second screw 20 is still used to connect the upper and lower templates 32, so as to avoid changes in the overall structure of the lower module 1 or the upper module 4 during the disassembly of the robot.

[0032] Furthermore, the inner surface of any template 32 contacts the outer surface of another template 32, forming a stacked effect of two templates 32. In the stacked state, when the templates 32 are not in use, they can be stacked to facilitate storage or transportation. The track 10 is fitted inside the outer guide groove 12 to form a limiting effect. A connecting block 18 is installed on the upper part of one side surface of the upper template 32. That is, from bottom to top, except for the first template 32, all the upper templates 32 need to have a connecting block 18 installed on the upper part of one side surface. A magnetic block 16 is magnetically attracted to the end of the track 10 of the upper template 32. The magnetic block 16 has a small magnetic force and can be moved by a large force. In order to facilitate the sliding of the magnetic block 16 inside the inner guide groove 13 without being affected by the magnetic force, magnetic material can be used. The magnetic block 16 is only installed at the connection between the magnetic block 16 and the template 32. Other parts have no magnetism or poor magnetic adsorption. The end of the track 10 is close to the connecting block 18. The magnetic block 16 itself is a block structure with appropriate magnetic force and can be placed on the end of the track 10. The surface of the magnetic block 16 is equipped with a guide rod 15, and an elastic element 14 is installed between the magnetic block 16 and the connecting block 18. When the magnetic block 16, guide rod 15 and other structures are used here, unlike when two templates 32 are installed, when the templates 32 are stacked, the elastic element 14, magnetic block 16 and connecting block 18 are all on the side of the upper template 32. When each template 32 needs to be used later, only the upper template 32 needs to be pushed on one side. When the track 10 enters the outer guide groove 12, the guide rod 15 enters the inner guide groove 13 and can be used directly.

[0033] The usage method of this embodiment is as follows: Depending on the actual construction situation or progress, such as when formwork construction is carried out after the steel reinforcement structure construction is completed, several stacked formwork templates 32 can be transported together. Using forklifts or other equipment, the formwork templates 32 can be transported to an area close to the steel reinforcement structure. The stacked formwork templates 32 are placed horizontally with the track 10 facing upwards. Because the formwork template 32 itself is not very thick, the uppermost formwork template 32, with the elastic element 14 on one side, experiences force. The track 10 of the uppermost formwork template 32 slides to one side along the outer guide groove 12 of the lower formwork template 32, causing the magnetic block 16, along with the guide rod 15, to simultaneously enter the inner guide groove 13. The two ends of the guide rod 15 are limited by the T-shaped inner guide groove 13. Before the upper formwork template 32 separates from the lower formwork template 32, the elastic element 14 is stretched and deformed. After the upper formwork template 32 separates from the lower formwork template 32, the magnetic block 16 and the top block 17 are pressed together and limited. While the external force is released, the upper formwork template 32 is moved downwards by gravity. When the elastic element 14 is in motion, it elastically resets, causing the downward template 32 to be subjected to an upward pulling force. The connection between the two templates 32 is still maintained, and the lower template 32 continues to move to one side until all templates are unfolded. Due to the elastic rebound of the elastic element 14, the sides of the adjacent templates 32 are pressed together, which facilitates the manual assembly of the first screw 6. If the lower module 1 or the upper module 4 is multi-layered, before installing the first screw 6, the upper and lower templates 32 need to be limited by the threaded area 7 and the screw hole 11 through the connecting rod 5 to facilitate the docking and installation of the upper and lower templates 32. Depending on the scale of the wind turbine foundation construction and the quality of the formwork 32, if the scale is small, half of the formwork 32 can be stacked together and unfolded on one side to form a semi-circular structure. After installing the first bolt 6, the half of the formwork 32 is placed vertically with the help of lifting components for processing. The other formwork 32 are then processed in sequence to complete the installation of the lower module 1. The upper module 4 needs to be installed on top of the upper steel structure, and the upper module 4 and the lower module 1 are connected by the telescopic rod 2 and the connecting ring 8 to improve the structural stability. At this time, the tracks 10 of each adjacent formwork 32 are connected to form a continuous track structure.External support rods and other components are erected to provide auxiliary support for the template 32. After the concrete is poured, when it is necessary to disassemble the template 32, the track robot 22 can be installed on the track 10. The track robot 22 moves forward along the track 10. With the help of the ranging component 26, the first electric push rod 23 and the second electric push rod 24, the rotating screw sleeve 27 is engaged with the bolt head of the first screw 6. The motor drives the rotating screw sleeve 27 to rotate, thereby disassembling the bolt. Due to the action of the second screw 20 and the connecting rod 5, there will be no large displacement between the templates 32, which allows the track robot 22 to travel continuously on the track 10. After the first screw 6 of one circle of template 32 is disassembled, the track robot 22 is disassembled and installed on the track 10 of another circle of template 32. After all the first screw 6 are disassembled, the reverse can be reversed and the connecting rod 5 can be removed, and then the second screw 20 can be removed. During pouring, some small concrete particles may seep into the outer guide groove 12, but due to the complex structure and large concrete particles, they are difficult to penetrate into the inner guide groove 13. If the formwork 32 is stuck to the concrete structure, a pry bar can be used to directly insert it into the outer guide groove 12 or the inner guide groove 13 to remove the formwork 32 outwards. The pry bar must be ensured not to affect the overall structure of the outer guide groove 12 or the inner guide groove 13. The grooves need to be cleaned before subsequent reuse. The telescopic rod 2 is detachable and can be retracted for easy storage or transportation. Furthermore, it should be noted that when the structural strength requirements of the formwork 32 are not high or the pressure is not significant, the connection of the end plates 19 of the upper and lower formwork 32 can be achieved solely through the threaded area 7 of the connecting rod 5, thus eliminating the need for installing and removing the second screw 20.

[0034] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
