[0020] like Figures 1 to 7 As shown, a double-sided sealed fastening connector includes a main body isolation stabilizing seat 1 with a central axis in the up and down direction. The main body isolation stabilizing seat 1 is composed of three matching support columns with diameters decreasing from top to bottom, and is used as an isolation structure when in use. The upper and lower sides of the matching support columns are both conical structures, so that they have reliable heat insulation when in use and can play a certain heat dissipation matching effect. The upper end of the main body isolation stabilizing seat 1 is provided with an integrally formed cylindrical fastening safety connection seat 2, which is the tail end when the whole is fastened, ensuring the strength of the main body when fastened. The lower end of the main body isolation stabilizing seat 1 is provided with an integrally formed main body fastening connection column 3, and the outer side of the main body fastening connection column 3 is provided with a fastening connection external thread. Through this structure, the outer side fastening connection is performed, and the fastening matching can be performed like a screw. The interior of the main isolation stabilizing seat 1 is provided with a hollow isolation safety groove 4, the upper end of the fastening safety connection seat 2 is provided with a first fastening combination threaded hole 5 that is in communication with the hollow isolation safety groove 4, and the lower end center position of the main body fastening connection column 3 is provided with a second fastening combination threaded hole 6 that is in communication with the hollow isolation safety groove 4, which can be fastened inside and can meet the fastening fit in the up and down directions.
