The rotating block 10 is located at one end of the two groups of rotating rods 9 away from the moving block 8. The limiting plate 11 is located on the top of the rotating block 10. When the PT trolley is placed on the top of the moving plate 2, the PT trolley can be limited by the limiting assembly 4. When the moving plate 2 is displaced, it can be prevented from being offset and causing damage.

[0028] Among them, a first thread groove is opened inside the moving block 8, and the internal structure size of the first thread groove is designed to correspond to the external structure size of the forward and reverse screw rods 7. The moving block 8 is connected to the forward and reverse screw rods 7 through the first thread groove, and the first thread groove is threadedly connected to the forward and reverse screw rods 7, so that the moving block 8 can be threadedly connected to the forward and reverse screw rods 7.
