Since the adjusting bolt 9 is threadedly connected to the threaded hole on the adjusting plate 7, the rotation of the adjusting bolt 9 can make the adjusting plate 7 move along the axial direction of the limiting slide rod 8, and then can pull one end of the steel cable 5 to move, thereby realizing the adjustment operation of the prestressed tendon, and the entire adjustment operation is flexible and convenient.
[0027] Reference Figure 1 , Figure 3 The outer cover of the anchor block 6 is buckled with an inner cover 11, and a sealing ring 10 is fitted at the port of the inner cover 11. The inner cover 11 is fixedly connected to the outer surface of the substrate 1 by bolts, and the outer sleeve of the base 2 is sleeved with a plastic steel sleeve 12. The substrate 1 and the inner cover 11 are both located inside the plastic steel sleeve 12. The port of the plastic steel sleeve 12 is buckled with an end cover 13, and the end cover 13 is snap-fitted and installed with the plastic steel sleeve 12. The inner cover 11 can be buckled on the outside of the anchor block 6 to seal and protect the anchor block 6 and the structure on the anchor block 6.

[0028] Working principle: When in use, first pass the steel cable 5 through the inside of the substrate 1 and the base 2, then install the substrate 1 and the base 2 at the specified position, and then adjust the position of the two ends of the steel cable 5 as needed. When adjusting, use an external tool to twist the adjusting bolt 9 to rotate. Since the adjusting bolt 9 is threadedly connected to the adjusting plate 7, the adjusting plate 7 can slide along the axial direction of the limiting slide rod 8. Since one end of the steel cable 5 is fixedly connected to the adjusting plate 7, the movement of the adjusting plate 7 can effectively pull one end of the steel cable 5 to achieve the adjustment operation of the prestressed tendons. After the adjustment is completed, the inner cover 11 is buckled on, and then the end cover 13 is buckled on the port of the plastic steel sleeve 12 to achieve double sealing operation.
