[0020] The working principle and beneficial effects of the utility model are as follows:

[0021] In the utility model, the base is provided with a mounting cavity, and sliding rails are mounted on both sides of the base, and the fixing seat can be slidingly arranged on the two sliding rails at the same time, and the design provides extremely smooth sliding conditions for the movement of the fixing seat. In building construction, when the reinforcing steel bars at the end of the precast pile are adjusted, the position of the fixing seat needs to be accurately controlled to ensure that the end of the reinforcing steel bar can accurately reach the required adjustment position. When the end of the reinforcing steel bar needs to be extended outward by a certain length to meet the lapping requirement of the pile cap reinforcing steel bar, the smooth sliding of the fixing seat on the sliding rail can accurately move the fixing seat to the corresponding position, so that the adjustment error of the end of the reinforcing steel bar can be controlled within a very small range, effectively ensuring the quality of the connection between the precast pile and the pile cap, and improving the integrity and stability of the building foundation structure.

[0022] The adjusting component, mounted on a fixed base, drives the sliding component to slide, enabling precise control of the rebar end position. In building construction, the positional accuracy of the precast pile rebar ends is crucial. During the connection between the precast pile and the foundation cap, the rebar ends need to be accurately inserted into the pre-drilled holes in the cap or precisely overlapped with the cap rebar. By precisely driving the sliding component within the groove through the adjusting component, the rebar end, housed in the fixed cavity, can be moved to a specified precise position. For example, when a rebar end needs to be extended outwards by a certain length to meet the overlap requirements with the cap rebar, the adjusting component can smoothly push the sliding component within the groove according to the set displacement, ensuring the rebar end accurately reaches the required position. This ensures the quality of the connection between the precast pile and the cap, improving the overall integrity and stability of the building's foundation structure.

[0023] The operation of this rebar adjustment fixture is simple and intuitive, allowing construction workers to quickly learn how to use it. First, the ends of the precast pile's rebars are inserted sequentially into the corresponding fixed cavities of the sliding components. Then, according to the specific requirements of the precast pile and subsequent construction stages, such as connection to the pile cap, the adjusting components drive the sliding components to slide within the groove, adjusting the position of the rebar ends. Finally, after adjustment, the rebars are removed from the fixed cavities. The entire operation process is clear and easy to understand, requiring no advanced professional skills from construction workers, reducing training costs and improving the overall work efficiency of the construction team.

DETAILED DESCRIPTION

[0030] In order to more clearly illustrate the technical solutions of the embodiments of the present application or the prior art, specific embodiments of the present application will be described below with reference to the drawings. Obviously, the drawings described below are only some embodiments of the present application, and for those skilled in the art, other drawings can be obtained from these drawings without creative labor, and other embodiments can also be obtained.

[0031] In order to make the drawing simple, only the parts related to the present application are shown in each drawing, which does not represent the actual structure of the product. In addition, in order to make the drawing simple and easy to understand, in some drawings, only one of the components with the same structure or function is shown, or only one of them is marked. In this paper, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0032] In this paper, it should be noted that, unless otherwise specified and limited, the terms "mounting", "connection" and "connection" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium, or it can be connected inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0033] In addition, in the description of the present application, the terms "first", "second" and the like are only used for differentiation and description, and cannot be understood as indicating or implying relative importance.

[0034] Reference Figures 1-4 For the first embodiment of the present application, a multipurpose prefabricated pile end reinforcement adjusting tool is proposed, which comprises a base 6, the base 6 has a mounting cavity 601, the slide rails 602 are two, respectively arranged on both sides of the mounting cavity 601, the fixed seat 1 has a sliding groove 101, the fixed seat 1 is simultaneously slidably arranged on the two slide rails 602, the sliding part 2 is slidably arranged in the sliding groove, the sliding part 2 has a fixing cavity 201, the fixing cavity 201 is used for accommodating the end of the reinforcing steel bar, the adjusting part 3 is arranged on the fixed seat 1, and is used for driving the sliding part 2 to slide.

[0035] In this embodiment, the base 6 is provided with a mounting cavity 601, and slide rails 602 are mounted on both sides thereof. The fixed seat 1 can be simultaneously slidably arranged on the two slide rails 602, and this design provides extremely smooth sliding conditions for the movement of the fixed seat 1. In building construction, when the reinforcement at the end of the precast pile is adjusted, it is often necessary to accurately control the position of the fixed seat 1 to ensure that the end of the reinforcement can accurately reach the required adjustment position. When it is necessary to extend the end of the reinforcement by a certain length to meet the lapping requirements with the reinforcement of the pile cap, the smooth sliding of the fixed seat 1 on the slide rails 602 can accurately move the fixed seat 1 to the corresponding position, so that the adjustment error of the end of the reinforcement can be controlled within a very small range, effectively ensuring the quality of the connection between the precast pile and the pile cap, and improving the integrity and stability of the building foundation structure.

[0036] Moreover, this smooth sliding mechanism can also adapt to different speed adjustment requirements. Whether in the case of rapid adjustment of the positions of a large number of precast pile reinforcement ends or in the case of fine and slow adjustment operations, the fixed seat 1 can quickly and smoothly slide on the slide rails 602, meeting the accuracy and speed requirements of reinforcement end adjustment in various construction scenarios and greatly improving the work efficiency of reinforcement adjustment.

[0037] The base 6, as the supporting foundation of the entire tooling, has sufficient strength and stability. It can withstand various forces generated during the adjustment of the end of the reinforcement, such as friction when the fixed seat 1 slides, the weight of the reinforcement, and impact forces that may be generated due to improper operation. At the same time, the sliding fit between the slide rails 602 and the fixed seat 1 is very tight and stable. The slide rails 602 can effectively prevent the fixed seat 1 from loosening or deviating during sliding, ensuring that the fixed seat 1 always moves accurately along the predetermined track and ensuring the accuracy of the adjustment of the end of the reinforcement.

[0038] The design of the sliding groove 101 provided on the fixed seat 1 and the slidable sliding member 2 in the sliding groove 101 enables the tooling to flexibly adapt to different reinforcement end layouts in the precast pile. In actual building engineering, the specifications and sizes of precast piles are various, and the arrangement and number of internal reinforcement are also different. For example, some precast piles may have a circular cross-section with reinforcement uniformly distributed in a ring shape, and some may have a square cross-section with reinforcement arranged in a square grid. This structure of the tooling can be used to easily accommodate and position the end of each reinforcement by sliding the sliding member 2 in the sliding groove 101 to the appropriate position, through the use of multiple fixed seats 1 and sliding members 2, effectively solving the adjustment problems caused by differences in reinforcement layout in precast piles and improving the versatility and applicability of the tooling.

[0039] The adjusting member 3 is arranged on the fixed base 1 to drive the sliding member 2 to slide, which realizes the accurate control of the position of the reinforcing steel bar end. In the construction of the building, the position accuracy of the reinforcing steel bar end of the precast pile is required to be high. When the precast pile and the foundation slab are connected, the reinforcing steel bar end needs to be accurately inserted into the reserved hole of the foundation slab or accurately overlapped with the reinforcing steel bars of the foundation slab. The reinforcing steel bar end accommodated in the fixed cavity 201 can be moved to the specified accurate position by accurately driving the sliding member 2 to slide in the sliding groove 101 by the adjusting member 3. For example, when the reinforcing steel bar end needs to be extended outward by a certain length to meet the overlapping requirement with the reinforcing steel bars of the foundation slab, the adjusting member 3 can smoothly push the sliding member 2 to slide in the sliding groove 101 according to the set displacement, so that the reinforcing steel bar end accurately reaches the required position, ensuring the quality of the connection between the precast pile and the foundation slab, and improving the integrity and stability of the building foundation structure.

[0040] The fixed base 1 has sufficient strength and stability as the basic support structure of the tooling. It can withstand various forces generated during the adjustment of the reinforcing steel bar end, such as friction when the sliding member 2 slides, the weight of the reinforcing steel bar, and impact forces that may be generated due to improper operation, etc. In the construction site, when the workers use the adjusting tooling to adjust the reinforcing steel bars of the heavy and long precast pile, the fixed base 1 can still be stably placed on the workbench or the ground without shaking or deforming, providing a reliable installation foundation for the sliding member 2 and the adjusting member 3, ensuring the normal operation of the entire tooling, and ensuring that the adjustment of the reinforcing steel bar end can be smoothly carried out.

[0041] Meanwhile, the fixed cavity 201 of the sliding member 2 has a good fixing effect on the reinforcing steel bar end. After the reinforcing steel bar end is inserted into the fixed cavity 201, its shape and size design can prevent the reinforcing steel bar from shaking or deviating during the adjustment. For example, for reinforcing steel bars of different diameters, the fixed cavity 201 can be designed with an adjustable inner diameter to ensure that the reinforcing steel bar can be stably fixed in the fixed cavity 201 regardless of its thickness, further ensuring the accuracy and stability of the adjustment of the reinforcing steel bar end.

[0042] The sliding cooperation between the sliding groove 101 and the sliding member 2 is very smooth, which is beneficial to improve the work efficiency and reduce the wear of the parts. In the daily use of the adjusting tooling, the sliding member 2 needs to frequently slide in the sliding groove 101. The smooth sliding cooperation enables the sliding member 2 to quickly respond to the driving instructions of the adjusting member 3 and quickly move to the specified position, greatly shortening the adjustment time of each reinforcing steel bar end and improving the overall work efficiency. Moreover, the smooth sliding cooperation reduces the friction between the sliding member 2 and the sliding groove 101, prolongs the service life of the parts, reduces the maintenance cost of the tooling, and ensures the reliability and usability of the tooling in the long-term construction process.

[0043] The operation process of the reinforcing steel bar adjusting tool is simple and intuitive, and construction personnel can quickly get started. First, the end of the reinforcing steel bar of the precast pile is inserted into the fixed cavity 201 of the corresponding sliding member 2 in sequence; then, according to the specific requirements of the precast pile and the subsequent construction links such as connection with the pile cap, the sliding member 2 is driven to slide in the sliding groove 101 by the adjusting member 3 to adjust the position of the end of the reinforcing steel bar; finally, after the adjustment is completed, the reinforcing steel bar is taken out from the fixed cavity 201. The whole operation process is clear and easy to understand, and construction personnel do not need to have too high professional skills, which reduces the training cost of construction personnel and improves the overall work efficiency of the construction team.

[0044] Further, the sliding member 2 has a fixed hole 202, the adjusting member 3 is a lead screw, the adjusting member 3 is rotationally arranged on the fixed seat 1 and located in the sliding groove 101, and the adjusting member 3 is arranged in the fixed hole 202 for driving the sliding member 2 to slide.

[0045] In this embodiment, the adjusting member 3 adopts the design of a lead screw, which is rotationally arranged on the fixed seat 1 and located in the sliding groove 101, and drives the sliding member 2 to slide by cooperating with the fixed hole 202 of the sliding member 2. This structure brings very high precision to the adjustment of the position of the end of the reinforcing steel bar. The lead screw has good transmission precision. When the lead screw is rotated, the threads of the lead screw and the threads in the fixed hole 202 of the sliding member 2 interact with each other, and the rotational motion of the lead screw can be accurately converted into the linear sliding motion of the sliding member 2. Moreover, the lead screw driving mode can realize fine adjustment and meet the fine adjustment requirements of the position of the end of the reinforcing steel bar in different construction scenes. For example, in some special building projects such as large bridge foundation precast pile construction, which have very high requirements for the position of the end of the reinforcing steel bar, it may be necessary to fine-tune the position of the end of the reinforcing steel bar by 0.1 millimeter. The precise transmission characteristics of the lead screw make it easy to realize such fine-tuning operation, and ensure that the position of the end of the reinforcing steel bar always meets the strict construction standards.

[0046] When the lead screw as the adjusting member 3 drives the sliding member 2 to slide, it has high transmission efficiency and can quickly realize the adjustment of the position of the end of the reinforcing steel bar. In the construction site, a large number of precast piles need to be adjusted, and time is a key factor of efficiency. When the lead screw is rotated, the sliding member 2 will quickly slide in the sliding groove 101. Compared with some traditional manual adjustment methods such as manually pushing and pulling the sliding member, the lead screw driving can adjust the end of the reinforcing steel bar to the required position in a shorter time. This greatly improves the overall construction efficiency, ensures that the project can be completed on time, and reduces the risk of construction progress lag caused by the delay of the reinforcing steel bar adjustment process.

[0047] The screw rod is rotatably arranged on the fixed base 1, and the fixed base 1 serves as a support base of the whole tooling and provides a stable rotating environment for the screw rod, thereby ensuring that the adjusting part 3 can continuously and stably drive the sliding part 2 to slide. At the same time, the cooperation between the screw rod and the fixing hole 202 of the sliding part 2 is tight and stable. The threads of the screw rod and the threads in the fixing hole 202 are finely processed, and the engagement precision between them is high, which can effectively prevent slipping, loosening and other phenomena during transmission, ensure reliable power transmission, guarantee the accuracy and stability of the reinforcement end adjustment, and improve the construction safety factor.

[0048] The fixing hole 202 of the sliding part 2 not only serves to cooperate with the screw rod to realize transmission, but also serves to further fix the reinforcement end. When the reinforcement end is inserted into the fixing cavity 201 of the sliding part 2, the presence of the fixing hole 202 increases the constraint ability of the sliding part 2 on the reinforcement end, so that the reinforcement is more stable during adjustment and is not prone to shaking, deviation and other situations. In addition, the screw rod is located in the sliding groove 101, and the design of the sliding groove 101 provides a certain protection for the screw rod and the sliding part 2, preventing external objects such as tools, debris and the like from causing impact, damage and the like to the screw rod and the sliding part 2 during construction.

[0049] The structural design of the tooling can flexibly adapt to different reinforcement end layouts and specifications in the precast pile. Since the screw rod can independently drive each sliding part 2 to slide in the sliding groove 101, whether the reinforcement of the precast pile is distributed in a ring shape, a square shape or other irregular shapes, the positions of the sliding parts 2 can be adjusted to adapt to different reinforcement end adjustment requirements of different precast piles, thereby improving the versatility and adaptability of the tooling.

[0050] The operation process of the tooling remains simple and intuitive. The construction personnel only need to rotate the screw rod to adjust the position of the reinforcement end, without the need for complex operation skills or professional equipment. For example, at the construction site, the construction personnel can use ordinary wrenches and the like to rotate the screw rod, and gradually adjust the position of the reinforcement end according to the specific requirements of the precast pile and the subsequent construction links such as connection with the pile cap. The operation process is simple and easy to implement, reduces the training cost of the construction personnel, and improves the overall work efficiency of the construction team.

[0051] Further, the adjusting part 3 has an extending end 301 extending out of the fixed base 1 from the sliding groove 101, and the extending end 301 has a hexagonal protrusion 302.

[0052] In this embodiment, the extension end 301 of the adjusting member 3 is extended outside the fixed seat 1 by the sliding groove 101, and a hexagonal protrusion 302 is arranged at the extension end 301. This design greatly facilitates the operation of the adjusting member 3 by the construction personnel. On the construction site, the construction personnel usually uses various tools to complete the work tasks. The shape of the hexagonal protrusion 302 perfectly matches the common hexagonal wrench, and the construction personnel only needs to use the hexagonal wrench to clamp the hexagonal protrusion 302 to easily rotate the adjusting member 3, thereby driving the sliding member 2 to slide to adjust the position of the reinforcing bar end. This convenient operation mode enables the construction personnel to quickly move from one precast pile to another precast pile for operation, without the need to frequently change or search for special operation tools, greatly improving the adjustment work efficiency, shortening the adjustment time of the reinforcing bar end of each precast pile, ensuring that the entire precast pile reinforcing bar adjustment process can be efficiently completed, and reducing the risk of construction progress lag caused by the delay of reinforcing bar end adjustment.

[0053] Compared with some other shapes or designs that need special tools for operation, the hexagonal protrusion 302 is more versatile, and the construction personnel can more easily obtain and use the hexagonal wrench on the construction site. Even new employees can quickly get started, familiarize and master this operation mode, reducing the learning cost of the construction personnel for tool operation and improving the overall operation proficiency and work efficiency of the construction team.

[0054] Using the hexagonal wrench to rotate the adjusting member 3 through the hexagonal protrusion 302 can achieve more accurate control of the rotation angle of the adjusting member 3. In building construction, the adjustment of the reinforcing bar end position of the precast pile often needs to be accurate to the millimeter level to ensure accurate connection with the subsequent foundation structure such as the pile cap. By accurately controlling the rotation angle of the adjusting member 3 through the hexagonal wrench, this rotation angle can be accurately converted into the linear sliding displacement of the sliding member 2, thereby achieving precise adjustment of the reinforcing bar end position. For example, when it is necessary to accurately extend the end of a reinforcing bar by 5 millimeters to achieve perfect lapping with the pile cap reinforcing bar, the construction personnel can use the hexagonal wrench to accurately rotate the adjusting member 3 according to the pre-calculated rotation angle of the adjusting member 3, so that the sliding member 2 accurately moves the reinforcing bar end to the specified position with an error controlled within a very small range, effectively ensuring the quality of the connection between the precast pile and the pile cap, and improving the integrity and stability of the building foundation structure.

[0055] The design of the extension end 301 extending to the outside of the fixed seat 1 optimizes the overall structural layout of the tool to a certain extent. On the construction site, the precast pile steel bar adjustment tool may be disturbed by various external forces, such as vibration of surrounding construction equipment, accidental collision of construction personnel, etc. By setting the extension end 301 on the outside, the construction personnel do not need to excessively approach other components inside the fixed seat 1 when operating, reducing the impact of external forces that may occur during the operation process on the internal structure of the tool, such as the sliding piece 2 and the sliding groove 101, etc., ensuring the stability of the internal structure of the tool, ensuring that the steel bar end adjustment work can be carried out in a relatively stable environment, reducing the occurrence of inaccurate steel bar end position adjustment caused by external interference, and improving the reliability and service life of the tool.

[0056] Further, it further comprises a limiting clamp 7, which is arranged on the fixed seat 1 and is used to fix or cancel the relative position of the fixed seat 1 and the sliding rail 602.

[0057] In this embodiment, the limiting clamp 7 is arranged on the fixed seat 1 and can fix the relative position of the fixed seat 1 and the sliding rail 602, which is crucial in the process of adjusting the precast pile end steel bar. After the fixed seat 1 is moved to the appropriate position on the sliding rail 602 by driving the sliding piece 2 to slide through the adjusting piece 3, the relative position of the fixed seat 1 and the sliding rail 602 is fixed by the limiting clamp 7, which can ensure that the fixed seat 1 will not be displaced due to external interference in the subsequent operation process, thereby ensuring the accuracy of the steel bar end position and laying a solid foundation for the accurate connection of the precast pile and the subsequent structure components such as the pile cap, and improving the integrity and stability of the building foundation structure.

[0058] Moreover, this precise fixing method can also adapt to the construction needs at different stages. In each link of the steel bar end adjustment, such as initially adjusting the steel bar end to a rough position and then finely adjusting it, the relative position of the fixed seat 1 and the sliding rail 602 can be fixed or canceled by the limiting clamp 7 in a timely manner to meet the operation requirements under different precision requirements, making the entire steel bar adjustment process more orderly and accurate, effectively avoiding the accumulation of adjustment errors caused by position changes, and improving the work efficiency and quality of the steel bar adjustment.

[0059] The limiting clamp 7 plays a role of stable support between the fixed seat 1 and the sliding rail 602. In the construction site, the environment is relatively complex, and the tool may be affected by various external forces, such as vibration of surrounding construction equipment, collision of workers working nearby, etc. After the limiting clamp 7 fixes the relative position of the fixed seat 1 and the sliding rail 602, the fixed seat 1 can still be stably maintained at the adjusted position even under these external forces, without shaking, loosening or accidentally sliding along the sliding rail 602, etc.

[0060] The limiting clamp 7 not only can fix the relative position of the fixed seat 1 and the slide rail 602, but also can conveniently cancel the fixation. This ability of flexible switching of the fixation state makes the tooling better adapt to different construction scenes and operation requirements. In the construction process, sometimes the fixed seat 1 needs to be frequently moved to adjust the reinforcement end of different precast piles. At this time, the limiting clamp 7 can be canceled to fix the relative position of the fixed seat 1 and the slide rail 602, so that the fixed seat 1 can freely slide on the slide rail 602 to quickly reach the position of the next precast pile for adjustment operation. When reaching the target precast pile position and completing the preliminary adjustment, the limiting clamp 7 can be used in time to fix the relative position of the fixed seat 1 and the slide rail 602, so as to carry out more detailed reinforcement end adjustment work.

[0061] Further, the slide rail 602 has a first limiting groove 603, the fixed seat 1 has a second limiting groove 604, and the limiting clamp 7 is slidingly arranged in the second limiting groove 604 and slides into or out of the first limiting groove 603 after sliding, for fixing or canceling the fixation of the fixed seat 1.

[0062] In the embodiment, the first limiting groove 603 of the slide rail 602, the second limiting groove 604 of the fixed seat 1, and the limiting clamp 7 which can slide in the second limiting groove 604 together constitute a set of precise fixation and positioning system. In the construction, the adjustment accuracy of the reinforcement end of the precast pile is extremely high. For example, when the precast pile is connected with the pile cap, the reinforcement end needs to be accurately inserted into the reserved hole of the pile cap or accurately overlapped with the reinforcement of the pile cap, and the error usually needs to be controlled within a very small range. When the fixed seat 1 is moved to the appropriate position on the slide rail 602, the limiting clamp 7 is slid from the second limiting groove 604 to slide into the first limiting groove 603, so as to realize the precise fixation of the fixed seat 1, and ensure that the fixed seat 1 will not be displaced due to external interference in the subsequent operation process, thereby ensuring the precision of the position of the reinforcement end, laying a solid foundation for the accurate connection of the precast pile and the pile cap and other subsequent structural components, and improving the integrity and stability of the building foundation structure.

[0063] This precise fixation method can also adapt to the construction requirements at different stages. In each link of the reinforcement end adjustment, such as first adjusting the reinforcement end to the approximate position and then finely adjusting, the limiting clamp 7 can be slid in time to fix or cancel the fixation of the fixed seat 1, so as to meet the operation requirements under different accuracy requirements, make the whole reinforcement adjustment process more orderly and precise, effectively avoid the accumulation of adjustment errors caused by position changes, and improve the work efficiency and quality of the reinforcement adjustment.

[0064] Further, the second limiting groove 604 has a receiving groove 605, the limiting clamping piece 7 has a clamping groove 701, and the fixing seat 1 further comprises an arc-shaped clamping piece 8 arranged in the receiving groove 605 and being a resilient clamping piece. After the limiting clamping piece 7 is slid, the arc-shaped clamping piece 8 acts on the clamping groove 701 to fix the limiting clamping piece 7.

[0065] In this embodiment, the arc-shaped clamping piece 8 is arranged in the receiving groove 605 and is a resilient clamping piece. After the limiting clamping piece 7 is slid to the position, the arc-shaped clamping piece 8 acts on the clamping groove 701 to fix the limiting clamping piece 7. This design provides a strong guarantee for the stability of the entire reinforcing steel bar adjusting tool. In building construction, the precision requirement of the reinforcing steel bar adjustment at the end of the precast pile is extremely high, and the stable state of each component of the tool is crucial to achieve accurate adjustment. Through the reliable fixation of the arc-shaped clamping piece 8 to the limiting clamping piece 7, the relative position of the fixing seat 1 and the sliding rail 602 can be accurately locked, thereby ensuring that the fixing seat 1 will not be displaced due to external interference in the subsequent operation process, thereby ensuring the accuracy of the position of the reinforcing steel bar end, laying a solid foundation for the accurate connection of subsequent structural components such as the precast pile and the pile cap, and improving the integrity and stability of the building foundation structure.

[0066] Moreover, this fixing mode can remain stable during long-term construction use. Even in the case of frequent reinforcing steel bar adjustment operations and complex construction site environments, the arc-shaped clamping piece 8 can continuously and tightly clamp in the clamping groove 701 of the limiting clamping piece 7 due to its elastic properties, ensuring that the limiting clamping piece 7 is always in the correct fixed position and maintaining the overall stability of the tool, effectively reducing the accumulation of adjustment errors caused by component loosening and improving the work efficiency and quality of reinforcing steel bar adjustment.

[0067] The fixing mode of the arc-shaped clamping piece 8 to the limiting clamping piece 7 is simple and convenient to operate. When it is necessary to fix the limiting clamping piece 7, the limiting clamping piece 7 is only needed to be slid to the predetermined position, and the arc-shaped clamping piece 8 will automatically clamp into the clamping groove 701 under its own elastic action to complete the fixation of the limiting clamping piece 7. When it is necessary to release the limiting clamping piece 7, only appropriate external force is needed to make the arc-shaped clamping piece 8 disengage from the clamping groove 701 to achieve the release of the limiting clamping piece 7. This convenient and quick operation mode enables the construction personnel to quickly switch between fixing and releasing the limiting clamping piece 7, meeting the flexibility requirements of tool operation in different construction scenarios. For example, when dealing with a large number of precast piles, the construction personnel can quickly fix the limiting clamping piece 7 at the corresponding position of each precast pile for reinforcing steel bar end adjustment, and after completion, the limiting clamping piece 7 can be quickly released to move to the next precast pile position, improving the construction efficiency and meeting the timeliness requirements of reinforcing steel bar end adjustment of precast piles in building construction.

[0068] Further, the limiting clamping piece 7 is rotationally and slidably arranged in the second limiting groove 604, the clamping groove 701 is an arc-shaped groove, the end of the clamping groove 701 is provided with an unlocking guide surface 702 for unlocking the limiting clamping piece 7, and the arc-shaped clamping piece 8 is configured to slide out of the clamping groove 701 under the action of the unlocking guide surface 702 after the rotation of the limiting clamping piece 7.

[0069] In the embodiment, the limiting clamping piece 7 is rotationally and slidably arranged in the second limiting groove 604, and the combined movement mode cooperates with the clamping groove 701 and the arc-shaped clamping piece 8, which brings high precision and flexibility to the operation of the reinforcing steel bar adjusting tool. When the limiting clamping piece 7 needs to be unlocked to move the fixing base 1 for the next adjustment, the unlocking guide surface 702 plays a key role. Only by applying appropriate rotation operation to the limiting clamping piece 7, the end of the arc-shaped clamping piece 8 can smoothly slide out of the clamping groove 701 under the guidance of the unlocking guide surface 702, realizing the quick unlocking of the limiting clamping piece 7, so that the fixing base 1 can be freely slid to a new position for reinforcing steel bar end adjustment. The mechanism of precise fixing and convenient unlocking effectively avoids the accumulation of adjustment errors caused by incoherent fixing or unlocking operation, improves the work efficiency and quality of reinforcing steel bar adjustment, and meets the flexibility requirements of different precast pile reinforcing steel bar end adjustment.
