DETAILED DESCRIPTION

[0021] like Figures 1 to 8A dual-fixation heat dissipation fastener is shown. It includes a conical first fastening column 1, with an integrally formed cylindrical second fastening column 2 positioned to the right of the first fastening column 1. Together, they form the main structure of the fastener. A first fastening thread groove is formed on the outer conical surface of the first fastening column 1, serving as the first fastening structure for mating. The outer cylindrical surface of the second fastening column 2 is provided with integrally formed, circumferentially evenly distributed reinforcement safety columns 3. These columns enhance the overall structural strength and serve as a cohesive heat dissipation structure during use, ensuring reliable heat resistance and allowing for hand-held fastening during installation. A cylindrical positioning assembly hole 4 is provided at the center of the left end face of the first fastening column 1 to meet the requirements for positioning and connection. A fastening stopper hole 6 is provided within the positioning assembly hole 4, with its central axis perpendicular to the central axis and extending through the outer side, providing a preventive stopper for the positioning structure. A second fastening connection groove 5 is provided at the center position of the right end face of the second fastening connection column 2, and a second fastening connection thread is provided on the inner cylindrical surface of the second fastening connection groove 5, which is the fastening structure of the second fastening connection position. An integrally formed sealing stabilization combination column 7 is provided at the center position of the left end face of the second fastening connection groove 5, so that the internal structure position has reliable support strength and has a stop function. The left end face of the second fastening connection groove 5 is located on the outside of the sealing stabilization combination column 7 and is provided with a cylindrical sealing matching connection groove 8, which can cooperate with the sealing assembly for a tight fitting connection. A cylindrical safety avoidance matching groove 9 is provided at the center position of the right end face of the sealing stabilization combination column 7, so that the center position has a reliable isolation function and better heat resistance during use. When in use, it can meet the fastening connection of the two-way fastening components on both sides. By setting a reinforcement structure on the main structure, it can not only ensure the strength during fastening, but also play a role in heat dissipation. The internal fastening position is set with a safety avoidance groove, which can make the interior play a role in heat insulation, so that the overall heat resistance during use is better, and can meet the safe use requirements of high-temperature components during fastening connections.
