[0002] During the maintenance of municipal pipelines, according to requirements, it may be necessary to fabricate and place a steel reinforcement cage, and then insert a grouting pipe into the steel reinforcement cage for grouting.

[0003] For example, the patent with the publication number CN216520287U provides a grouting pipe threading tool for the maintenance of municipal pipelines, belonging to the technical field of pipe threading tools, including a grouting pipe, a receiving pipe, a thin pipe, and a sliding ring. The receiving pipe is threadedly connected to the bottom of the grouting pipe, the thin pipe is threadedly connected to the bottom of the receiving pipe, and the sliding ring is movably connected to the outer side of the top of the grouting pipe. By setting a lower movable block, a sliding ring, and an upper movable block, the lower movable block and the upper movable block have good limiting and fixing effects, can limit the lower limiting rod and the upper limiting rod, and make them rotate along the rotating shaft for supporting work. When in use, the upper movable block is pushed downward to be clamped and fixed with the clamping block, so that the lower limiting rod and the upper limiting rod incline outward, bulging the limiting block, enabling the grouting pipe to be clamped on the outer side or inner wall of the municipal pipeline to be repaired, making the grouting more stable and labor-saving, without the need for the user to always hold the grouting pipe, and facilitating the pipe threading and grouting operation.

[0004] During the use of the above device, due to the structural relationship between the two limiting rods, its supporting effect on the vertical gravity is poor, and all the gravity is applied to the clamping block. This form will cause the force on the clamping block to exceed the load, resulting in damage to the clamping block and displacement of the limiting rod, leading to construction accidents. Therefore, a grouting pipe threading tool is proposed to solve the above problems. Content of the Utility Model
