[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0017] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model.

[0018] As Figure 1 , Figure 2 , Figure 3 shown, the adjustable anti-floating anchor rod positioner includes an upper positioning ring 1 and a lower positioning ring 13. An anchor rod can be arranged in the upper positioning ring 1 and the lower positioning ring 13, and the two position the anchor rod up and down.

[0019] A number of upper fixing plates 2 are fixedly connected to the outer surface of the upper positioning ring 1, and one end of each upper fixing plate 2 is hinged to the first rotating plate 4; a number of lower fixing plates 14 are fixedly connected to the outer surface of the lower positioning ring 13, and one end of each lower fixing plate 14 is hinged to the second rotating plate 15, and the other end of the first rotating plate 4 is hinged to the other end of the second rotating plate 15.

[0020] Specifically, through holes are provided on both the upper fixing plate 2 and the lower fixing plate 14. A first bolt 3 is arranged in the through hole. The first bolt 3 is the hinge shaft, and a first nut 5 is connected to the outer surface of the first bolt 3. A second bolt 6 is arranged at the hinge joint of the first rotating plate 4 and the second rotating plate 15. The second bolt 6 is the hinge shaft of the two, and a second nut 7 is threadedly connected to the outer surface of the second bolt 6.

[0021] Further, three upper fixing plates 2 are provided on the upper positioning ring 1, and three lower fixing plates 14 are provided on the lower positioning ring 13. Each upper fixing plate 2 is connected to the lower fixing plate 14 through a two-link mechanism (the first rotating plate 4 and the second rotating plate 15), thereby forming three auxiliary support structures.

[0022] Further, a through hole is opened on the upper positioning ring 1, and a threaded cylinder 8 is threadedly connected in the through hole. A threaded rod 9 is threadedly connected in the threaded cylinder 8, and the other end of the threaded rod 9 is fixedly connected to the lower positioning ring 13. In this way, the outer surface of the threaded cylinder 8 is provided with an external thread, which is matched with the thread in the through hole of the upper positioning ring 1; the inner surface of the threaded cylinder 8 is provided with an internal thread, which is matched with the threaded rod 9. Preferably, the top of the threaded cylinder 8 extends out of the upper positioning ring 1 and is provided with a turning handle 11, so that it is convenient to rotate the threaded cylinder 8.

[0023] Further, as Figure 3 shown, in order to limit the rotation of the threaded cylinder 8, two annular plates 10 are provided on the outer surface of the threaded cylinder 8; among them, the upper annular plate 10 is located above the upper fixing plate 2, and the lower annular plate 10 is located between the upper positioning ring 1 and the lower positioning ring 13, and the length of the turning handle 11 is greater than the width of the annular plate 10, thereby restricting the downward displacement of the turning handle 11.

[0024] Further, in order to facilitate the limiting and fixing of the anchor rod in the positioning ring, a number of fixing bolts 12 are provided on the inner surfaces of the upper positioning ring 1 and the lower positioning ring 13, and the free ends of the fixing bolts 12 abut against the internal anchor rod.

[0025] The working principle of the present utility model is:

[0026] During use, by rotating the threaded cylinder 8, the threaded cylinder 8 will gradually move upward. At the same time, the threaded cylinder 8 drives the lower annular plate 10 to move upward as well until it reaches the bottom of the upper positioning ring 1. The lower annular plate 10 is limited in position, and during this process, the distance between the upper positioning ring 1 and the lower positioning ring 13 increases.

[0027] Meanwhile, the two positioning rings will drive multiple first rotating plates 4 to rotate, changing the angle between the first rotating plates 4 and the second rotating plates 15. After adjusting the angle of each first rotating plate 4, pass multiple anchor rods through the two positioning rings respectively, and then rotate multiple fixing bolts 12 to make the multiple fixing bolts 12 squeeze and fix the anchor rods.

[0028] The above are only the preferred embodiments of the present utility model. It should be noted that for those skilled in the art, without departing from the overall concept of the present utility model, several changes and improvements can still be made, and these should also be regarded as the protection scope of the present utility model.
