[0027] The use of fasteners is indispensable in construction projects, as they facilitate the installation and combination of different components and are easy to operate. When the main body is a large-scale equipment and accessories need to be installed or the thickness of the connector is very large and the bolt length is very long, stud bolts are usually used for fixed installation. However, traditional stud bolts may become detached after installation due to thermal expansion and contraction and vibration during use, making it difficult to meet actual use requirements. By providing a fastening structure 4, the installation of the stud bolts is strengthened to meet actual use requirements.

[0028] Reference Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, the outer wall of the connecting block 1 is evenly provided with anti-skid grooves 5, the outer wall of the connecting block 1 is provided with a lubrication structure 6, the lubrication structure 6 includes an oil inlet 601 and a threaded plug 602, the oil inlet 601 is provided on the outer wall of the connecting block 1, the inside of the oil inlet 601 is provided with a threaded plug 602, the inside of the connecting block 1 is provided with guide grooves 603 on both sides of one end of the oil inlet 601, the middle position of the inside of the threaded rod 2 is provided with a guide groove 604, and the threaded rod on one side of the guide groove 604 is provided with a guide groove 604. 2 is evenly provided with oil outlets 605, an inner wall on one side of the oil inlet 601 is provided with an internal thread, the oil inlet 601 and the threaded plug 602 are threadedly connected, the guide groove 603 and the guide groove 604 conflict with each other, the oil inlet 601 and the guide groove 604 are connected with each other through the guide groove 603, the side of the oil outlet 605 away from the guide groove 604 extends to the outside of the threaded rod 2, and the oil outlets 605 are evenly distributed on the outside of the guide groove 604 inside the threaded rod 2.

[0029] During the use of the stud bolts, they may need to be disassembled and assembled during subsequent use. However, traditional stud bolts are difficult to rotate easily after long-term use, and thus have certain inconveniences during the disassembly process, making it difficult to meet actual use needs. By providing a lubrication structure 6, it is easy to operate during the disassembly process, which greatly increases the practicality of the device.
