[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0027] like Figure 1 and Figure 2 As shown, an anti-loosening bolt tightening sleeve device includes: a top plate 20, which is disc-shaped, and the top of the top plate 20 is connected to a corresponding rotating tool. This is existing technology and will not be described in detail here.

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a sleeve structure is installed at the bottom of the top plate 20 for tightening bolts. The sleeve structure includes: a through post 21, a fixed ring 22, a suction plate 24, an adapter cylinder 40, and an adapter plate 43. The through post 21 is fixedly connected to the bottom of the top plate 20, the fixed ring 22 is fixedly connected to the bottom wall of the through post 21, the suction plate 24 is fixedly connected to the top wall of the fixed ring 22, the adapter cylinder 40 is slidably connected to the wall of the fixed ring 22, and the adapter plate 43 is movably connected to the wall of the adapter cylinder 40. The adapter cylinder 40 and the adapter plate 43 can tighten bolts.

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the through-post 21 is cylindrical, the fixed ring 22 is annular, and multiple identical through-posts 21 are evenly arranged at the bottom of the top plate 20. The bottom of each through-post 21 is simultaneously connected to the top of the fixed ring 22. The suction plate 24 is composed of a capsule-shaped plate at the top and symmetrical cylinders at the bottom. The symmetrical cylinders of the suction plate 24 are fixedly connected to the top of the fixed ring 22. The capsule-shaped plate of the suction plate 24 has magnetic force. The adapter cylinder 40 is a hollow annular shape with a hexagonal internal space. The adapter plate 43 is a rectangular plate with a diagonal texture on its wall surface, which faces the inside of the adapter cylinder 40. The cylindrical structure also includes a limiting plate 23, a sliding plate 41, and a slider 42. The limiting plate 23 is symmetrically fixedly connected to the top two sides of the fixed ring 22. The sliding plate 41 is symmetrically fixedly connected to the top of the adapter cylinder 40. The slider 42 is symmetrically fixedly connected to the arc surfaces on both sides of the adapter cylinder 40. The limiting plate 23 is a rectangular plate, and the top of the limiting plate 23 can also be fixedly connected to the bottom of the top plate 20. The sliding plate 41 is an inverted L-shaped plate. The sliding plate 41 on each side can slide along the symmetrical limiting plates 23 on each side. The cavity of the fixed ring 22 is symmetrically provided with rectangular grooves for sliding the slider 42. One of the rectangular grooves in the cavity of the fixed ring 22 is in an open state.

[0030] In practical use, the suction plate 24 and the top of the bolt are attached and adsorbed. Then, the adapter cylinder 40 will move downward due to gravity. When the adapter cylinder 40 moves, it will drive the slide plate 41 to slide between the symmetrical limiting plates 23. The adapter cylinder 40 will also drive the slider 42 to slide in the symmetrical rectangular groove on the wall of the fixed ring 22. When the adapter cylinder 40 slides to the lowest point of the bolt, it can stop sliding. At this time, rotating the top plate 20 can drive the adapter cylinder 40 to tighten or loosen the bolt in the cavity of the adapter cylinder 40. When the diameter of the bolt needs to be matched, the adjusting column 44 is rotated. As the adjusting column 44 rotates, it will drive the adapter plate 43 and the straight plate 45 to move towards the bolt. After the oblique wall of the adapter plate 43 and the bolt wall are attached, the rotation of the adjusting column 44 can be stopped.

[0031] In summary, by setting up a sleeve structure, the tightening points of bolts of different heights can be automatically adapted, and the magnetic suction plate 24 can prevent the bolts from falling off. Therefore, this solution can tighten bolts of different sizes without replacement, thus effectively saving the time required for replacement and installation.

[0032] like Figure 5As shown, the wall surface of the adapter plate 43 is provided with an adjustment structure, which includes an adjustment column 44 and a straight plate 45. The adjustment column 44 is rotatably connected to the flat wall surface of the adapter plate 43, and the straight plate 45 is fixedly connected to the wall surface of the adapter plate 43, which is the same as the adjustment column 44. The adjustment column 44 is a cylindrical shape with an arc surface and threads. The adjustment column 44 can pass through one of the sliders 42 and the adapter cylinder 40 and be threadedly connected to the slider 42. The straight plate 45 is located above the adjustment column 44 and can also pass through the wall surface of the slider 42 and the adapter cylinder 40. The adjustment column 44 is located in the open rectangular groove in the cavity of the fixed ring 22.

[0033] In practical use, when it is necessary to adapt the diameter of the bolt, the adjusting column 44 is rotated. As the adjusting column 44 rotates, the adapter plate 43 and the straight plate 45 will move towards the bolt. After the oblique grooved wall surface of the adapter plate 43 and the bolt wall surface are in contact, the adjusting column 44 is stopped from rotating.

[0034] In summary, by setting up an adjustable structure and utilizing the movable adapter plate 43 to match the inner wall of the adapter cylinder 40, bolts of different diameters can be accommodated, thereby further expanding the applicability of this solution.

[0035] Working principle: The suction plate 24 adheres to the top of the bolt and attracts it. Then, the adapter cylinder 40 moves downward due to gravity. When the adapter cylinder 40 moves, it drives the slide plate 41 to slide between the symmetrical limiting plates 23. The adapter cylinder 40 also drives the slider 42 to slide in the symmetrical rectangular groove on the wall of the fixed ring 22. The sliding stops when the adapter cylinder 40 slides to the lowest point of the bolt. At this time, rotating the top plate 20 can drive the adapter cylinder 40 to tighten or loosen the bolt in the cavity of the adapter cylinder 40. When the diameter of the bolt needs to be matched, the adjusting column 44 is rotated. As the adjusting column 44 rotates, it drives the adapter plate 43 and the straight plate 45 to move towards the bolt. After the oblique wall of the adapter plate 43 and the bolt wall are in contact, the rotation of the adjusting column 44 is stopped.
