The grouting pipe 3 is provided on the side of the sleeve 1. The grouting pipe 3 allows the discharge of excess grouting material or gas during the grouting process to ensure the integrity and uniformity of the grouting. The interior of the sleeve 1 is provided with a steel bar 4. The interior of the sleeve 1 is provided with a fixing assembly 5, which includes a spring 501 and a fixing block 502. The end of the spring 501 is provided with a fixing block 502. The spring 501 provides elastic restoring force, so that the fixing block 502 can automatically adjust the clamping force according to the diameter of the steel bar 4. The fixing block 502 is in direct contact with the steel bar 4 and is tightly clamped by the action of the spring 501 to prevent it from moving or shaking. The fixing assembly 5 is arranged in a circular array with multiple groups. The shape and position of the fixing block 502 are adapted to the steel bar 4. The multiple groups of fixing assemblies 5 arranged in a circular array can ensure that the steel bar 4 is fixed in all directions within the sleeve 1.

[0027] The interior of the sleeve 1 is provided with a positioning assembly 6, and the positioning assembly 6 is axially symmetrically arranged inside the sleeve 1. The positioning assembly 6 includes a first positioning block 601, a second positioning block 602, a third positioning block 603 and a support plate 604. The side of the first positioning block 601 is provided with a second positioning block 602, the side of the second positioning block 602 is provided with a third positioning block 603, and the side of the third positioning block 603 is provided with a support plate 604. The setting of the support plate 604 provides support for the placement of the steel bar 4 with the smallest diameter. A grouting groove 7 is provided on the surface, and the grouting groove 7 passes through the positioning component 6 to guide the flow of the grouting material, ensuring that the grouting material can evenly cover the gap between the steel bar 4 and the sleeve 1. A guide groove 8 is provided on the surface of the positioning component 6, and the guide groove 8 corresponds to the grouting groove 7, and is used to guide the grouting material to flow through the guide groove 8 and the grouting groove 7 in the positioning component 6, ensuring that the grouting material can flow to the bottom position of the connection between the steel bar 4 and the positioning component 6, and avoid the steel bar 4 blocking the grouting groove 7 and the grouting hole 9, so that the grouting material cannot flow into the steel bar The bottom part of the reinforcement 4 ensures that the grouting material can be fully filled into each gap, ensuring the smooth grouting process of the reinforcement 4. The surface of the positioning component 6 is provided with a grouting hole 9, which allows the grouting material to smoothly enter the interior of the sleeve 1, and works together with the grouting groove 7 and the guide groove 8 to ensure that the grouting material is fully filled. The first positioning block 601, the second positioning block 602 and the third positioning block 603 are arranged in a stepped manner. The stepped arrangement can adapt to reinforcement 4 of different diameters and enable the reinforcement 4 to be inserted step by step. The steel bar 4 is guided to the center position step by step to reduce eccentricity, ensure the center position of the steel bar 4 in the sleeve 1, and realize accurate positioning of the steel bar 4. The grouting groove 7 and the grouting hole 9 are arranged in a circular array on the surface of the first positioning block 601, the second positioning block 602 and the third positioning block 603. The circumferential array arrangement further improves the uniformity and efficiency of grouting. The guide groove 8 is arranged in a circular array on the surface of the first positioning block 601, the second positioning block 602 and the third positioning block 603, and the position of the guide groove 8 corresponds to the grouting groove 7.

[0028] When the steel bar 4 is inserted into the sleeve 1, once it contacts the fixing block 502, it will push the fixing block 502 to expand outward, compressing the spring 501. The spring 501 then generates a reaction force, driving the fixing block 502 to tightly clamp the steel bar 4, achieving adaptive positioning. Steel bars 4 of different diameters will produce different degrees of compression effects on the spring 501, and then automatically adjust its clamping force to ensure the stability of the clamping effect. In addition, the first positioning block 601, the second positioning block 602 and the third positioning block 603 are arranged in a stepped shape. This design can perfectly adapt to steel bars 4 of various diameters, broadening the application range of the sleeve 1. When steel bars 4 of various sizes are inserted into the sleeve 1, the positioning blocks of corresponding sizes can be used to ensure The steel bar 4 is always in the center of the sleeve 1, and the steel bar 4 is accurately positioned, which effectively prevents it from shifting inside the sleeve 1, avoids the stress concentration problem caused by eccentricity, prevents the reduction of connection strength, and improves the safety of the overall structure. At the same time, it significantly reduces the shaking of the steel bar 4 during use, enhances the stability of the connection, and injects grouting material into the sleeve 1 through the grouting pipe 2, and realizes the circulation of grouting material through the grouting groove 7 and the grouting hole 9. At the same time, through the cooperation of the grouting groove 7 and the guide groove 8, the grouting material can be fully and comprehensively filled into the sleeve 1, and then the excess grouting material or gas in the grouting process is discharged through the slurry outlet pipe 3 to ensure the integrity and uniformity of the grouting. Specific embodiment two:

[0030] Reference Figure 7 , a precise positioning full grouting sleeve, based on the basic structure of a specific embodiment, further discloses the following content. When the steel bar 4 of larger diameter is inserted into the sleeve 1, precise positioning is achieved through the fixing assembly 5 and the positioning assembly 6, and the end of the steel bar 4 is positioned against the surface of the third positioning block 603. Subsequently, in the grouting link, the grouting material flows smoothly through the grouting groove 7 and the grouting hole 9. At the same time, since the positions of the grouting groove 7 and the guide groove 8 correspond to those of the guide groove 8, even if the steel bar 4 blocks the grouting groove 7 and the grouting hole 9 on the third positioning block 603, the grouting material can still continue to flow with the help of the grouting groove 7 on the second positioning block 602, and guide the grouting material flowing through the grouting groove 7 through the guide groove 8 on the third positioning block 603 where the steel bar 4 is inserted, and introduce it into the gap at the bottom of the steel bar 4, thereby ensuring comprehensive and sufficient filling between the steel bar 4, the sleeve 1 and the grouting material, and ensuring the smooth progress of the grouting process.

[0031] In summary:

[0032] 1. The fixing assembly 5 and the positioning assembly 6 are used to realize that when the steel bar 4 is inserted into the sleeve 1, once it contacts the fixing block 502, it will push the fixing block 502 to expand outward, compressing the spring 501. The spring 501 then generates a reaction force, driving the fixing block 502 to tightly clamp the steel bar 4, realizing adaptive positioning. Steel bars 4 of different diameters will produce different degrees of compression effect on the spring 501, and then automatically adjust its clamping force to ensure the stability of the clamping effect. In addition, the first positioning block 601, the second positioning block 602 and the third positioning block 603 is arranged in a stepped manner. This design can perfectly adapt to steel bars 4 of various diameters, broadening the application range of the sleeve 1. When steel bars 4 of various sizes are inserted into the sleeve 1, the positioning blocks of corresponding sizes can ensure that the steel bars 4 are always in the center of the sleeve 1, and accurately position the steel bars 4, effectively preventing them from shifting inside the sleeve 1, avoiding stress concentration problems caused by eccentricity, preventing the decrease in connection strength, and improving the safety of the overall structure. At the same time, it significantly reduces the shaking of the steel bars 4 during use and enhances the stability of the connection.
