[0060] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0061] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0062] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0063] The wind turbine hybrid tower is assembled from multiple prefabricated segments. In actual operation, the wind pressure load, wind shear stress, overturning moment, and self-weight load at different heights (bottom, middle, and top) of the wind turbine hybrid tower vary significantly. To meet the overall structural strength, stiffness, and stability design standards, avoid safety hazards such as localized stress concentration and structural deformation, and ensure the long-term safety and durability of the wind turbine hybrid tower, it is necessary to differentiate the prefabricated segments with different wall thicknesses according to the actual stress conditions of each tower segment. This optimizes the adaptation of the wind turbine hybrid tower structure. Therefore, to adapt to the wind load and structural requirements of different tower segments, segments of various thicknesses need to be produced during the manufacturing of wind turbine hybrid towers.

[0064] Segment forming can be made using segment forming molds. The segment forming mold includes a frame bottom mold, on which are set a fixed inner mold, an end mold, and a slidable outer mold. The frame bottom mold, the fixed inner mold, the outer mold, and the end mold together form a forming cavity. The thickness of the forming cavity in each set of segment forming molds is fixed.

[0065] A single set of forming molds can produce segments of a specific thickness, but multiple sets of forming molds are needed to manufacture segments of different thicknesses. Since the production of wind turbine hybrid towers requires segments of various thicknesses, each thickness specification requires a separate forming mold with corresponding parameters. It is impossible for a single set of molds to be compatible with the production of segments of multiple thicknesses. Therefore, manufacturers need to stock a large number of forming molds of different specifications, which not only significantly increases the production costs of mold procurement, processing, maintenance, and warehousing, but also complicates the process of alternating and changing multiple sets of molds, thus reducing the production efficiency of segments.

[0066] In view of this, this application provides a tube sheet forming mold, comprising: a base; a first tube sheet mold disposed on the base; a second tube sheet mold disposed on the base and connected to the first tube sheet mold at the same end in its extending direction; the base, the first tube sheet mold, and the second tube sheet mold together forming a tube sheet forming cavity; and an adjusting mold assembly located within the tube sheet forming cavity, used to adjust the distance between the first and second tube sheet molds, so that the thickness of the tube sheet formed within the tube sheet forming cavity is adjustable. This application embodiment uses a base, the first tube sheet mold, and the second tube sheet mold to jointly form a tube sheet forming cavity, and provides an adjusting mold assembly within the tube sheet forming cavity for adjusting the distance between the first and second tube sheet molds. The thickness of the tube sheet forming cavity can be changed by adjusting the distance between the first and second tube sheet molds using the adjusting mold assembly, allowing tube sheets of different thicknesses to be produced as needed using only one set of tube sheet forming molds.

[0067] The following describes an optional technical solution for a segment forming mold in this embodiment, with reference to the accompanying drawings.

[0068] like Figure 1 and Figure 2 As shown, this embodiment provides a tube segment forming mold, which includes a base 100.

[0069] The first segment mold 200 is set on the base 100.

[0070] The second segment mold 300 is mounted on the base 100 and is connected to the same end of the first segment mold 200 in the same extension direction.

[0071] The base 100, the first segment mold 200, and the second segment mold 300 together form the segment forming cavity 800.

[0072] Adjustable mold assembly 400 is located inside the tube forming cavity 800. Adjustable mold assembly 400 is used to adjust the distance between the first tube forming mold 200 and the second tube forming mold 300 so that the thickness of the tube forming inside the tube forming cavity 800 is adjustable.

[0073] The base 100 serves as the basic load-bearing body of the entire segment forming mold, possessing high structural strength, overall rigidity, and flatness. It provides stable installation support and positioning benchmarks for various components on the base 100, avoiding structural deformation and displacement during mold assembly and concrete pouring. It also provides ample arrangement space and load-bearing foundation for the first segment mold 200, the second segment mold 300, and the segment forming cavity 800.

[0074] The first segment mold 200 is a one-sided forming mold body set on the base 100. The first segment mold 200 is used together with the second segment mold 300 to define the outer boundary of the target segment and to serve as a relative reference mold body when adjusting the segment thickness. The first segment mold 200 is installed at a predetermined position on the base 100 and can be connected to the base 100 by welding, detachable screw connection or snap-fit, and is arranged along the segment extension direction so that its forming surface forms a contour surface that matches the shape of the target segment.

[0075] The second segment mold 300 is a forming mold body on the other side of the base 100. The second segment mold 300 is connected to the first segment mold 200 at the same end in the extension direction, so that together with the first segment mold 200, they form the relative boundary of the segment forming cavity 800. The second segment mold 300 is also mounted on the base 100, and its forming surface is opposite to the first segment mold 200 to define the spatial boundary in the thickness direction of the segment.

[0076] The segment forming cavity 800 is a semi-enclosed space formed by the base 100, the first segment mold 200 and the second segment mold 300, used for pouring concrete and forming the segment entity. The internal space contour of the segment forming cavity 800 is consistent with the shape of the target segment, and its thickness dimension can change with the arrangement of the adjusting mold assembly 400.

[0077] The adjusting mold assembly 400 is assembled and arranged in the internal space of the tube forming cavity 800. It is an independent thickness adjustment structure that can be stably assembled and flexibly adapted to the installation position inside the tube forming cavity 800. By changing its own thickness or moving its position, it can adjust the effective distance between the first tube forming mold 200 and the second tube forming mold 300, thereby changing the thickness of the tube forming cavity 800.

[0078] In the process of producing tunnel segments, this segment forming mold first uses a base 100 to precisely position and stably fix the first segment mold 200 and the second segment mold 300, ensuring that the first segment mold 200 and the second segment mold 300 are in a standard alignment state and together with the base 100, form a basic segment forming cavity 800. When production requires the preparation of segments of different thicknesses, there is no need to replace the entire segment forming mold. The effective distance between the first segment mold 200 and the second segment mold 300 can be precisely adjusted by changing the thickness or moving the position of the mold assembly 400. The effective distance between the first segment mold 200 and the second segment mold 300 directly determines the effective forming thickness of the segment forming cavity 800. After adjusting the distance and fixing the positioning by adjusting the mold assembly 400, the forming thickness of the segment forming cavity 800 can be changed accordingly. Subsequently, concrete raw materials are poured into the segment forming cavity 800, and after curing, segments of the corresponding thickness specifications are obtained, realizing the prefabrication production needs of multiple thickness segments with a single mold.

[0079] This embodiment changes the fixed thickness of the segment forming cavity 800 in the segment forming mold and the production method where a single segment forming mold can only produce segments of a single thickness. By installing an adjustable mold assembly 400 inside the segment forming cavity 800, the forming thickness of the segment forming cavity 800 can be flexibly and precisely adjusted. There is no need to separately equip or replace the entire forming mold for different thicknesses; a single segment forming mold can produce segments of multiple thicknesses. Therefore, using this segment forming mold for multi-thickness segment production can reduce the number of molds required for segment production, lower production costs such as mold procurement, site storage, and equipment maintenance. It also eliminates the tedious processes of frequent mold changes, re-hoisting and re-aligning, and debugging and calibration, shortening mold changeover time, improving operational continuity, and increasing segment production efficiency.

[0080] See Figure 1 , Figure 2 and Figure 6 In some embodiments, the adjusting mold assembly 400 includes a plurality of tube sheet adjusting molds 410 located in the tube sheet forming cavity 800. The plurality of tube sheet adjusting molds 410 are stacked sequentially along the direction from the second tube sheet mold 300 to the first tube sheet mold 200. Each tube sheet adjusting mold 410 is detachably connected to the second tube sheet mold 300, and the tube sheet adjusting mold 410 adjacent to the second tube sheet mold 300 abuts against the second tube sheet mold 300.

[0081] The segment forming cavity 800 is the space for casting and forming segments, and all segment adjustment molds 410 are arranged inside the segment forming cavity 800. Multiple segment adjustment molds 410 are assembled in a uniform arrangement direction, extending from the second segment mold 300 towards the first segment mold 200. The segment adjustment molds 410 are fitted together and stacked in sequence, with a neat overall arrangement and tight fit.

[0082] Each segment adjustment mold 410 can be independently assembled and disassembled. All segment adjustment molds 410 are detachably connected to the second segment mold 300. Operators can disassemble, add, or replace any segment adjustment mold 410 individually according to production needs without altering the overall installation of the second segment mold 300 and the base 100. The segment adjustment mold 410 closest to the second segment mold 300 directly abuts against the inner surface of the second segment mold 300. The segment adjustment molds 410 in each layer are also tightly abutted against each other. After assembly, the overall structure is stable, preventing loosening or displacement during operation.

[0083] During normal production of tube segments, the effective distance is the distance between the first tube segment mold 200 and the second tube segment mold 300 minus the portion occupied by the adjusting mold assembly 400. This is the actual thickness of the tube segment forming cavity 800, and the thickness of the produced tube segment is the actual thickness of the tube segment forming cavity 800.

[0084] When producing segments of different thicknesses, the thickness of the adjusting mold assembly 400 itself can be changed by altering the number of segments adjusting molds 410 assembled, thereby adjusting the effective forming distance between the first segment mold 200 and the second segment mold 300. Increasing the number of segments adjusting molds 410 increases the space occupied inside the segment forming cavity 800, decreases the effective forming distance between the first segment mold 200 and the second segment mold 300, and correspondingly reduces the forming thickness of the segment forming cavity 800; conversely, decreasing the number of segments adjusting molds 410 decreases the space occupied inside the segment forming cavity 800, increases the effective forming distance between the first segment mold 200 and the second segment mold 300, and simultaneously increases the forming thickness of the segment forming cavity 800.

[0085] Throughout the adjustment process, the installation positions of the second segment mold 300, the first segment mold 200, and the base 100 remain fixed. Thickness adjustment can be completed by simply disassembling and assembling the segment adjustment mold 410. After the adjustment is completed, raw materials can be poured into the segment forming cavity 800 to produce segments of the corresponding specifications.

[0086] This embodiment allows for graded adjustment of the thickness of the mold adjustment component, thereby achieving graded adjustment of the thickness of the segment forming cavity 800, which can adapt to the production requirements of precast segments with various wall thicknesses. The segment adjustment mold 410 has a simple assembly and disassembly process, eliminating the need for relocation, hoisting, and calibration of the entire segment forming mold, significantly simplifying the thickness adjustment operation steps.

[0087] The segment adjustment mold 410 in this embodiment can be repeatedly disassembled and reused, eliminating the need to equip a complete set of molding equipment for segments of different thicknesses. This reduces the costs associated with mold procurement, storage, and maintenance, and improves the applicability of the segment forming mold.

[0088] See Figure 1 and Figure 2 In other embodiments, an installation assembly is also included, which is connected to the second segment mold 300, and each segment adjustment mold 410 is detachably connected to the installation assembly.

[0089] The mounting assembly is uniformly assembled onto the second segment mold 300, forming a stable mounting carrier. All segment adjustment molds 410 no longer directly connect to the second segment mold 300, but are instead uniformly assembled onto the mounting assembly. The mounting assembly can individually position and fix each segment adjustment mold 410. Each segment adjustment mold 410 and the mounting assembly are detachably assembled, allowing for the individual assembly and disassembly of one or more segment adjustment molds 410 according to production needs. The assembly structure is neat, and the connection points are evenly stressed.

[0090] During the production of tube segments, the mounting assembly is first fixed onto the second tube segment mold 300. Then, according to the required tube segment thickness, the corresponding number of tube segment adjustment molds 410 are sequentially installed on the surface of the mounting assembly. When it is necessary to adjust the thickness of the tube segment forming cavity 800, the tube segment adjustment mold 410 can be directly added to or removed from the mounting assembly to change the overall arrangement length of the tube segment adjustment molds 410, thereby adjusting the internal space dimensions of the tube segment forming cavity 800 and completing the adjustment of the tube segment thickness.

[0091] By using the installation components to transfer and fix the segment adjustment mold 410, the installation benchmark of all segment adjustment molds 410 can be unified, improving the overall flatness and positional accuracy of the segment adjustment mold 410 after assembly, and making the disassembly and assembly of the segment adjustment mold 410 more orderly and convenient.

[0092] See Figure 1 , Figure 2 , Figure 3 and Figure 6 Specifically, the mounting components include mounting plate 510 and multiple mounting bolts 520.

[0093] The mounting plate 510 is provided with multiple mounting holes 511. One mounting bolt 520 is connected to the second segment mold 300 through one mounting hole 511, and the remaining mounting bolts 520 are connected to the segment adjustment mold 410 through the mounting holes 511.

[0094] The mounting plate 510 is a single rigid plate structure with several through mounting holes 511 evenly distributed on its surface. All mounting holes 511 are arranged in an orderly manner along the length of the mounting plate 510. Multiple mounting bolts 520 are matched with the diameter specifications of each mounting hole 511. Some mounting bolts 520 pass through the corresponding mounting holes 511 to lock and fix the mounting plate 510 to the second segment mold 300. The remaining mounting bolts 520 pass through the other mounting holes 511 to achieve the assembly connection between the mounting plate 510 and each segment adjustment mold 410. All connection points are reasonably distributed to ensure that the mounting plate 510 and the segment adjustment mold 410 are subjected to balanced stress after assembly.

[0095] During assembly, first, select the corresponding mounting bolts 520 and pass them through the mounting holes 511 on the mounting plate 510 to firmly fix the mounting plate 510 to the surface of the second segment mold 300. Then, determine the number of segment adjustment molds 410 to assemble according to the required segment thickness. Place the segment adjustment molds 410 onto the designated positions on the mounting plate 510 in sequence, and use the remaining mounting bolts 520 to pass through the corresponding mounting holes 511 to lock the segment adjustment molds 410 onto the mounting plate 510. To add or remove segment adjustment molds 410, simply loosen the mounting bolts 520 at the corresponding positions to disassemble or add the segment adjustment molds 410, thereby changing the arrangement length of the segment adjustment molds 410 and adjusting the thickness of the segment forming cavity 800.

[0096] The assembly structure, consisting of a mounting plate 510 and mounting bolts 520, is simple and reliable, and the disassembly and assembly operations are convenient and efficient. Multiple mounting holes 511 can flexibly adapt to the installation requirements of different numbers of segment adjustment molds 410. Simultaneously, the multi-point bolt locking method improves the stability of the segment adjustment mold 410 during operation, effectively preventing loosening or displacement during the casting process, ensuring accurate segment forming dimensions, and facilitating later maintenance and replacement of components.

[0097] See Figure 1 and Figure 2In some embodiments, both the first segment mold 200 and the second segment mold 300 are arc-shaped, the second segment mold 300 is located inside the first segment mold 200, and the arc of the second segment mold 300 is the same as that of the first segment mold 200. The first segment mold 200 and the second segment mold 300 are parallel.

[0098] The first segment mold 200 and the second segment mold 300 adopt the same arc-shaped structure. When arranged in parallel, the resulting cavity contour perfectly matches the arc-shaped segment shape of the wind turbine hybrid tower, enabling the one-time casting of segment products conforming to the designed arc. This embodiment ensures uniform wall thickness throughout the segment, allowing the formed segment to directly adapt to the assembly requirements of the wind turbine hybrid tower body. Simultaneously, the symmetrical arc structure allows for smoother flow of the castable material within the cavity, effectively reducing molding defects and improving the overall molding quality of the segment.

[0099] See also Figure 1 and Figure 2 In other embodiments, the segment adjustment mold 410 is an arc-shaped adjustment plate, and the arc of the adjustment plate is the same as that of the second segment mold 300.

[0100] The segment adjustment mold 410 is configured as an arc-shaped adjustment plate, and the arc-shaped adjustment plate maintains the same curvature as the second segment mold 300. The arc-shaped adjustment plate can completely fit the inner surface of the second segment mold 300, and there will be no problems such as local warping or gaps after stacking and assembly. This embodiment can maintain the overall curvature of the segment forming cavity 800, ensure that the segment thickness remains uniform along the arc direction, further ensure that the segment's external dimensions and mechanical properties meet the standards, and at the same time, the arc-shaped adjustment plate has a more reasonable stress distribution, which can improve its own structural durability.

[0101] See Figure 1 Figure 2 and Figure 4 In some possible embodiments, a first mounting bracket 210 is also included. The first mounting bracket 210 is detachably connected to the base 100 and is connected to the first segment mold 200. The first mounting bracket 210 is used to mount the first segment mold 200 on the base 100.

[0102] The first mounting bracket 210 serves as an independent connecting component to assemble and connect the first segment mold 200 to the base 100. The detachable connection allows workers to easily disassemble, repair, and fine-tune the position of the first segment mold 200 independently. The first mounting bracket 210 provides multi-point support and positioning for the first segment mold 200, enhancing its structural stability during pouring and vibration, preventing displacement or deformation, and reducing wear caused by direct contact between the first segment mold 200 and the base 100, thus extending the component's service life.

[0103] See Figure 1 and Figure 2 In some possible embodiments, a second mounting bracket 310 is also included. The second mounting bracket 310 is detachably connected to the base 100 and is connected to the second segment mold 300. The second mounting bracket 310 is used to mount the second segment mold 300 on the base 100.

[0104] The second mounting bracket 310 bears the load and positions the second segment mold 300. Its detachable assembly makes disassembly, maintenance, and replacement of the second segment mold 300 more convenient. The second mounting bracket 310 can evenly distribute the load on the second segment mold 300, making the overall stress on the second segment mold 300 more balanced, effectively preventing deformation of the second segment mold 300 during long-term use, ensuring the installation accuracy of the second segment mold 300, thereby stabilizing the overall shape of the segment forming cavity 800 and ensuring stable segment production dimensions.

[0105] See Figure 1 and Figure 2 In some embodiments, two side mold assemblies 600 are also included, which are respectively connected to the same end of the second segment mold 300 and the first segment mold 200 in the extension direction.

[0106] The base 100, the first segment mold 200, the second segment mold 300, and the side mold assembly 600 together form the segment forming cavity 800.

[0107] Two side mold components 600 are respectively arranged at both ends of the overall mold, enclosing the ends of the first segment mold 200 and the second segment mold 300. Together with the base 100, the first segment mold 200, and the second segment mold 300, they form a completely enclosed segment forming cavity 800, which can effectively prevent concrete material from overflowing from the mold ends during pouring and vibration, ensuring the normal progress of the pouring operation. The completely enclosed cavity structure can strictly limit the axial shape and end face dimensions of the segment, ensuring that the various external parameters of the precast segment meet the design standards.

[0108] The addition of a side mold assembly 600 to seal both ends of the cavity makes the overall structure of the tube forming cavity 800 more regular and robust, and the mutual coordination and positioning of each component improves the overall stability of the entire mold during operation.

[0109] See Figure 1 , Figure 2 and Figure 4In another embodiment, the side mold assembly 600 includes a side template 610 and a fixing plate 620. The side template 610 in one side mold assembly 600 is detachably connected to the first segment mold 200, and the side template 610 in the other side mold assembly 600 is rotatably connected to the first segment mold 200.

[0110] The fixing plate 620 is connected to the second segment mold 300, and the side template 610 is detachably connected to the fixing plate 620.

[0111] When demolding the segments, remove the connecting bolts between the first mounting bracket 210 and the base 100, and open the detachable connection between the side template 610 and the first segment mold 200. Then the first segment mold 200 can be rotated open to remove the segments.

[0112] Alternatively, the side templates 610 in the side mold assemblies 600 at both ends are rotatably connected to the first segment mold 200. In this way, during demolding, the connecting bolts of the two side templates 610 and the fixing plate 620 are removed, and the two side templates 610 are rotated open to assist in demolding from this position.

[0113] The side templates 610 employ both detachable and rotatable connection methods, and together with the fixing plate 620 fixed to the second segment mold 300, they enable flexible opening and closing of the end of the segment forming cavity 800. The rotatable side template 610 can quickly open and close the segment molding cavity through a flipping action, meeting the needs of segment demolding, mold cleaning, and material casting. The detachable side template 610 facilitates individual disassembly, maintenance, and replacement of parts. These two connection methods work together to adapt to different operational requirements. After the side template 610 is closed, it is locked and fixed to the fixing plate 620, achieving a reliable seal of the end structure and ensuring the overall sealing of the segment forming cavity 800.

[0114] See Figure 2 , Figure 4 and Figure 5 In some embodiments, a reinforcing component 700 is also included. The reinforcing component 700 includes a fixing block 710 and a pressing block 720. The fixing block 710 is disposed on the side of the first segment mold 200 away from the second segment mold 300. The fixing block 710 has a through-hole groove 711. The pressing block 720 is inserted into the through-hole groove 711 and extends to the outside. The pressing block 720 is used to press the side template 610 against the first segment mold 200.

[0115] The fixing block 710 is fixedly installed on the outside of the first segment mold 200. The through slot 711 provides passage space for the extrusion block 720 to move in a directional manner. The extrusion block 720 can slide smoothly along the through slot 711 and extend to the outer area. After the side template 610 is closed, the extended extrusion block 720 can apply a pressing force to the side template 610 from the outside, so that the side template 610 fits tightly against the first segment mold 200, eliminating any looseness or gaps between the side template 610 and the first segment mold 200, and achieving reliable positioning of the side template 610.

[0116] The reinforcing component 700 uses the extrusion block 720 to press against the side formwork 610, which can improve the structural strength and locking effect of the side formwork 610 after it is closed, effectively resist the lateral pressure generated during concrete pouring and vibration, and prevent the side formwork 610 from shifting or reversing, which could cause problems such as material leakage and dimensional deviation.

[0117] See Figure 5 In some embodiments, the fixed block 710 is provided with a sliding groove 730, which is connected to the through groove 711. The inner side of the pressing block 720 is connected to a sliding block 740, which is located in the sliding groove 730 and slides in cooperation with the sliding groove 730. The end of the sliding groove 730 away from the through groove 711 is provided with a through hole 731. A threaded rod 750 is threadedly connected inside the through hole 731. The outside of the threaded rod 750 passes through the fixed block 710 and is connected to a knob 760. The sliding block 740 is provided with a threaded hole 741 on the side facing the threaded rod 750. The inner side of the threaded rod 750 is threadedly connected to the threaded hole 741 of the sliding block 740. A fixed bearing 770 is provided on the inner wall of the sliding groove 730, and the threaded rod 750 passes through the fixed bearing 770.

[0118] The sliding groove 730 communicates with the through groove 711, providing a unified movement track for the sliding block 740 and the pressing block 720. The sliding block 740 slides smoothly inside the sliding groove 730 along with the pressing block 720. The threaded rod 750 passes through the through hole 731 and is assembled with the fixed bearing 770. The fixed bearing 770 provides positioning support for the threaded rod 750, which can limit the axial position of the threaded rod 750 while ensuring that the threaded rod 750 can rotate flexibly. The knob 760 connected to one end of the threaded rod 750 is arranged on the outside of the fixed block 710 for easy manual operation. The other end of the threaded rod 750 is screwed into the threaded hole 741 on the surface of the sliding block 740, and the power is transmitted by means of the threaded transmission structure.

[0119] Rotating the outer knob 760 drives the threaded rod 750 to rotate synchronously. Through the threaded engagement, the sliding block 740 reciprocates linearly along the sliding groove 730, thereby causing the pressing block 720 to extend and retract. The overall transmission structure offers smooth transmission and high adjustment precision. The fixed bearing 770 reduces frictional resistance and component wear during the rotation of the threaded rod 750, extending the service life of the entire structure. The entire transmission mechanism is integrated inside the fixed block 710, with a compact layout that is less susceptible to external interference, enabling continuous and stable clamping and releasing operations on the side template 610.

[0120] See also Figure 5 In some other possible implementations, a limiting rod 780 is connected inside the sliding groove 730, and a limiting groove 742 is formed on the sliding block 740. The end of the limiting rod 780 extends into the interior of the limiting groove 742, and the limiting rod 780 is used to limit the sliding block 740.

[0121] The limiting rod 780 is fixedly installed inside the sliding groove 730 along the movement direction of the sliding block 740. The limiting rod 780 extends into the limiting groove 742 of the sliding block 740. The limiting groove 742 and the limiting rod 780 cooperate to form a guiding structure, which can constrain the movement trajectory of the sliding block 740, allowing the sliding block 740 to move back and forth only in a straight line, and preventing the sliding block 740 from deflecting or twisting inside the sliding groove 730. The limiting rod 780 and the limiting groove 742 maintain a cooperative state throughout the entire process, always guiding and constraining the sliding block 740, ensuring that the sliding block 740 and the pressing block 720 move synchronously and maintain a stable posture.

[0122] The limiting structure can effectively prevent the sliding block 740 from deflecting and jamming as the threaded rod 750 rotates, making the threaded transmission smoother, reducing the probability of mechanism failure, and extending the service life of the entire reinforcing assembly 700.
