Reinforcing hooks 9 are provided below the bolts 5. These slots provide a convenient channel for the installation of bolts 5. At the same time, each slot is provided with a bolt 5, and a reinforcing hook 9 is cleverly provided below the bolt 5. This not only enhances the connection strength between the bolt 5 and the positioning frame, but also further improves the stability of the bolt 5 during construction processes such as pouring cement through the hooking action of the reinforcing hook 9. In addition, the multiple reserved slots also enable the positioning device to easily meet the installation requirements of bolts 5 in different numbers and positions, improving its applicability and flexibility.

[0035] See Figure 1 , Figure 2 The top of the bolt 5 is threaded with a fastening nut 6. One side of the fastening nut 6 abuts against the top of the second positioning frame 4, which makes the bolt 5 more firmly fixed on the positioning frame during installation. At the same time, the abutment of one side of the fastening nut 6 against the top of the second positioning frame 4 provides additional support and fixation for the bolt 5. This fastening method not only enhances the connection strength between the bolt 5 and the positioning frame, but also further improves the positioning accuracy and stability through the fastening effect of the fastening nut 6.

[0036] The implementation principle of this utility model is as follows: First, the two sets of threaded sleeves 804 are screwed to change the distance between the first screw 803 and the second screw 805, thereby adjusting the height between the first positioning frame 3 and the second positioning frame 4. Then, the limiting screw 7 is inserted through the first positioning frame 3 and the second positioning frame 4 and fixed with a nut. Subsequently, the empty groove on the installed positioning frame is aligned with the bolt and inserted through the first positioning frame 3 and the second positioning frame 4. Then, it is tightened with a fastening nut. After that, the cement is poured. The double-layer positioning frame can further limit the bolt 5, and the first mounting frame 801, the second mounting frame 806, and the limiting screw 7 form a triangular structure, making the structure of the positioning frame more stable and less prone to shaking. During its installation, the possibility of bolt angle displacement when tightening the nut is reduced, improving its positioning accuracy. It also reduces the possibility of screw position displacement caused by the impact force generated when pouring cement, further improving the ease of use and positioning accuracy of the positioning device.
