When the fixing sleeve 31 is screwed inward to the outer wall of the screw 11, the threaded sleeve 21 moves inward synchronously, and the inner side of the limiting plate 22 is pressed against the outer wall of the object to be fixed 4.

[0028] In this embodiment, the U-shaped stud 1 has external threaded screws 11 at both ends for connecting the limiting component 2 and the fixing component 3.

[0029] Specifically, the inner side of the limiting plate 22 is provided with an arc-shaped groove 23 that matches the outer wall of the object to be fixed 4, and an elastic pad 24 is installed inside the arc-shaped groove 23. The shape of the elastic pad 24 matches the arc-shaped groove 23, and both are smaller than the inner dimension of the limiting plate 22. The end of the threaded sleeve 21 extends beyond one side of the limiting plate 22. The inner thread of the threaded sleeve 21 matches the outer thread of the fixing sleeve 31, and the inner diameter of the threaded sleeve 21 matches the outer diameter of the fixing sleeve 31.

[0030] In this embodiment, the limiting component 2 includes a threaded sleeve 21 and a limiting plate 22. The threaded sleeve 21 is fitted onto the screw 11 and engages with the fixing sleeve 31 via threads. The limiting plate 22 is fixed between the two threaded sleeves 21, and its inner side is provided with an arc-shaped groove 23 and an elastic pad 24 for conforming to the outer wall of the object 4 being fixed.

[0031] Specifically, the inner wall thread of the fixed sleeve 31 matches the outer wall thread of the screw 11. A rotating positioning disk 32 is fixed to the outside of the fixed sleeve 31. The size of the rotating positioning disk 32 is larger than that of the fixed sleeve 31. A positioning ring 33 extends from one side of the rotating positioning disk 32. The positioning ring 33 is sleeved on the outside of the extension of the threaded sleeve 21. The edges of the positioning ring 33 and the rotating positioning disk 32 are provided with multiple anti-slip grooves 34. The multiple anti-slip grooves 34 are evenly spaced on the outer wall of the rotating positioning disk 32. An adjustment part 35 is also provided on the fixed sleeve 31 on the other side of the rotating positioning disk 32.

[0032] Specifically, the adjustment part 35 and the fixed sleeve 31 have the same overall size, and the outer wall of the adjustment part 35 is provided with a plurality of evenly spaced strip grooves 36, the density of the plurality of strip grooves 36 being greater than that of the anti-slip grooves 34.

[0036] Specifically, manually rotating the rotating positioning disk 32 causes the fixed sleeve 31 to move inward along the screw 11.

[0037] Specifically, since the threaded sleeve 21 is threadedly engaged with the fixed sleeve 31, when tightened, the threaded sleeve 21 moves inward synchronously, pushing the limiting plate 22 to press the fixed object 4.

[0038] Specifically, if fine adjustments to the tightness are required, they can be made through the groove 36 of the adjustment section 35 to avoid being too tight or too loose.

[0039] Specifically, when the fixed sleeve 31 is fully tightened, the positioning ring 33 locks the extension of the threaded sleeve 21 to prevent it from rotating in the opposite direction and loosening.

[0040] In this embodiment, fixing can be completed simply by manually rotating the rotating positioning disc 32, making it suitable for confined spaces or emergency installation scenarios. The fixing sleeve 31 and the threaded sleeve 21 work together to ensure that the limiting plate 22 evenly presses against the object being fixed 4. It can adapt to objects 4 of different diameters or with uneven surfaces, such as pipes and cables, avoiding damage caused by hard contact. The elastic pad 24 absorbs vibration, and the positioning ring 33 prevents the threaded sleeve 21 from retracting, making it suitable for dynamic load environments such as vehicles and mechanical equipment. Different adjustment methods are provided: coarse adjustment using the rotating positioning disc 32 and fine adjustment using the adjustment part 35. This reduces stress concentration, extends service life, and facilitates smooth movement of the threaded sleeve 21.
