[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figure 1-4A bolt fastening and loosening mechanism is provided, comprising a mounting box 1. The mounting box 1 has an open top to support the rotation of a shaft 6. The shaft 6 is rotatably connected to the inner wall of the mounting box 1 via bearings. The bottom end of the shaft 6 penetrates the mounting box 1 and supports the installation of a screw 4. The screw 4 is fixedly mounted on the bottom end of the shaft 6. A loosening mechanism is installed on the shaft 6 to facilitate bolt loosening and fastening from the side, improving the versatility of bolt installation and loosening. An anti-slip pad 5 is fixedly installed on the bottom end of the mounting box 1. The anti-slip pad 5 is annular in shape and serves to protect the mounting surface during bolt installation, while also preventing slippage and ensuring stable bolt installation. A covering mechanism is installed on the mounting box 1 to cover the top of the bolt, improving its aesthetics.

[0021] In detail, a first disassembly block 7 is fixedly installed at the top of the shaft 6. The first disassembly block 7 is in the shape of a regular hexagon. By setting the regular hexagonal first disassembly block 7, it is convenient to use a wrench to disassemble the bolt.

[0022] Furthermore, the first disassembly block 7 is provided with a first disassembly groove 8, which is shaped like a cross groove. By providing the first disassembly groove 8 in the shape of a cross groove, it is convenient to use a screwdriver to disassemble the bolt.

[0023] Furthermore, the disassembly mechanism includes a gear ring 25, which is fixedly mounted on the shaft 6. The gear ring 25 is shaped like a frustum and is designed to mesh with the gear 24.

[0024] More specifically, the inner wall of the mounting box 1 is rotatably connected to a rotating rod 23 via bearings. The rotating rod 23 is used to support the installation of the gear 24. One end of the rotating rod 23 is fixedly mounted with the gear 24, which is frustum-shaped and meshes with a gear ring 25. The other end of the rotating rod 23 penetrates the surface of the mounting box 1, and a second disassembly block 21 is fixedly mounted on the other end. The second disassembly block 21 is hexagonal in shape, which facilitates the rotation of the rotating rod 23 using a wrench. The second disassembly block 21 has openings... There is a second disassembly groove 22, which is shaped like a cross groove. By setting the second disassembly groove 22 in the shape of a cross groove, it is easy to use a screwdriver to rotate the rotating rod 23. When it is necessary to disassemble the bolt from the side, hold the mounting box 1 and then use a wrench and screwdriver to rotate the second disassembly block 21. The second disassembly block 21 drives the rotating rod 23 to rotate, and the rotating rod 23 drives the gear 24 to rotate. The gear 24 meshes with the gear ring 25, which will drive the shaft 6 to rotate. During the rotation of the shaft 6, it will drive the screw 4 to rotate, making it easy for the screw 4 to be taken out of the threaded hole, thereby achieving the purpose of disassembling the bolt from the side and improving the diversity of bolt disassembly.

[0025] In general, the covering mechanism includes an annular groove 32, which is formed on the mounting box 1. The annular groove 32 is an annular groove, and the inner wall of the annular groove 32 is threaded. By setting the annular groove 32 with threads, it is convenient to receive the installation of the box cover 31. The inner wall of the annular groove 32 is threaded to the box cover 31. The box cover 31 is set to close the internal components of the mounting box 1, which helps to improve the aesthetics of the bolts.

[0026] Finally, the anti-slip mat 5 is made of rubber with anti-slip texture. Rubber is a highly elastic polymer material with reversible deformation. In terms of anti-slip performance, rubber has a high coefficient of friction, which can effectively increase the friction between contact surfaces and reduce slippage. Especially in wet or oily environments, its anti-slip effect is more significant. In terms of cushioning performance, due to its good elasticity, rubber can effectively absorb and disperse impact force, protecting equipment from damage. In terms of wear resistance, rubber has high wear resistance. Its flexible molecular chain structure can absorb and disperse external force, reduce wear, and extend service life. By setting the anti-slip mat 5, it serves to protect the installation surface during bolt installation and also plays an anti-slip role, which is conducive to the stable installation of bolts.

[0027] Working method: When it is necessary to remove the bolt, the cover 31 can be rotated to remove it from the annular groove 32. Then, the first disassembly block 7 can be rotated with a wrench or screwdriver. The first disassembly block 7 will drive the shaft 6 to rotate. When the shaft 6 rotates, it will drive the screw 4 to rotate, making it easier for the screw 4 to be removed from the threaded hole. When it is necessary to remove the bolt from the side, hold the mounting box 1 and then use a wrench and screwdriver to rotate the second disassembly block 21. The second disassembly block 21 will drive the rotating rod 23 to rotate. The rotating rod 23 will drive the gear 24 to rotate. The gear 24 meshes with the gear ring 25, which will drive the shaft 6 to rotate. During the rotation of the shaft 6, the screw 4 will rotate, making it easier for the screw 4 to be removed from the threaded hole. This achieves the purpose of removing the bolt from the side and improves the versatility of bolt disassembly.

[0028] Furthermore, by providing a cover 31, after the bolts are installed, the cover 31 is used to close the internal components of the installation box 1, which helps to improve the aesthetics of the bolts. At the same time, by providing an anti-slip pad 5 made of rubber with anti-slip texture, the rubber has a high coefficient of friction, which can effectively increase the friction between the contact surfaces and reduce slippage. During bolt installation, the rubber also has high wear resistance, and its flexible molecular chain structure can absorb and disperse external forces, reduce wear, and extend service life. By providing an anti-slip pad 5, the installation surface is protected, and it also plays a role in preventing slippage, which is conducive to the stable installation of the bolts.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
