[0019] Please see Figure 1-2 A prefabricated house wall connection device includes a connecting cylinder 1. Two adjusting components 2 are movably connected to the inner wall of the connecting cylinder 1 and are symmetrically distributed vertically. The opposing sides of the two adjusting components 2 extend to the top and bottom of the connecting cylinder 1, respectively. Positioning rings 3 are fixedly connected to the exterior of each adjusting component 2. Each adjusting component 2 includes a connecting frame 21. Two connecting frames 21 are slidably connected to the inner wall of the connecting cylinder 1 and are symmetrically distributed vertically. The opposing sides of the two connecting frames 21 extend to the top and bottom of the connecting cylinder 1, respectively. Two limiting bolts 22 are threadedly connected to the left side wall of the connecting cylinder 1 and are threadedly connected to the inner walls of the two connecting frames 21, respectively. A number of threaded holes, evenly distributed vertically, are opened inside each of the two connecting frames 21. The threaded holes are adapted to the limiting bolts 22. The interior of the connecting cylinder 1 is hollow, and its top and bottom are both open. Two circular grooves, symmetrically distributed vertically, are opened on the left side wall of the connecting cylinder 1 and are adapted to the limiting bolts 22.

[0020] The left side walls of both positioning rings 3 are fixedly connected to a first connecting plate 4. The opposite sides of both positioning rings 3 are movably connected to a rotating assembly 5, which includes a rotating ring 51. The opposite sides of both positioning rings 3 are rotatably connected to the rotating ring 51. The two rotating rings 51 are respectively sleeved on the outside of the two connecting frames 21. The right side walls of both rotating rings 51 are fixedly connected to a second connecting plate 52. The outer sides of the first connecting plate 4 and the second connecting plate 52 are each provided with two bolt connection holes that are symmetrically distributed from left to right. The opposite sides of the upper and lower rotating rings 51 are each threadedly connected to positioning bolts 53 that are threadedly connected to the opposite sides of the two positioning rings 3.
