After the position is adjusted, the installation ear plate 103 moves to avoid affecting the installation of the plug-in type welding intersecting node and avoiding unstable installation of the plug-in type welding intersecting node. The moving block 109 drives the convex limiting slider 3 to slide on the limiting slide rod 301 and the limiting slide groove 302, so that the limiting slide rod 301 and the limiting slide groove 302 horizontally limit the convex limiting slider 3, thereby horizontally limiting the moving block 109, avoiding the moving block 109 from rotating when the threaded rod 108 rotates, avoiding affecting the movement of the moving block 109, and reducing the wear of the moving block 109. The moving plate 106 drives the limiting block 4 in the limiting groove 40 2, and horizontally limit the movable plate 106 to prevent the movable plate 106 from being separated from the inserted ear plate 102, thereby preventing the mounting ear plate 103 from being separated and affecting the installation of the plug-in type welding intersecting node. The limit block 4 compresses and buffers the buffer spring 5, so that the buffer spring 5 can buffer between the mounting ear plate 103 and the inserted ear plate 102, reducing damage to the mounting ear plate 103 and the inserted ear plate 102. The threaded rod 108 rotates on the N-shaped connecting rod through the limit bearing 6, reducing the wear of the threaded rod 108 and the N-shaped connecting rod, and extending the service life of the threaded rod 108.
