The ball head 14 passes through the mounting hole 11 and is rotatably connected to the ball socket insert 3. The fastening spring 5 provides a fastening force for the ball socket insert 3 to reduce the extrusion deformation of the ball head 14 caused by thermal expansion, thereby avoiding the problem of loosening and shaking of the ball head 14. The adjustment block 2 and the ball socket insert 3 are of split design. After the ball head 14 and the ball socket insert 3 are matched, the adjustment block 2 can be adjusted in the X direction. Neither the ball head 14 nor the ball socket insert 3 is in direct contact with the mirror housing 1. The mirror housing 1 will not be subjected to the force generated by the high-temperature deformation of the ball socket insert 3, thereby solving the problem of high-temperature deformation and shaking of the mirror housing 1. The mirror housing 1 is made of PC+ABS plastic, the ball socket insert 3 is made of POM (polyoxymethylene), which improves the wear resistance and high temperature resistance of the ball socket insert 3, and the adjustment block 2 and the adjustment cover plate 4 are made of PA+GF55 (nylon and glass), which has high strength and toughness and low application cost. The adjustment block 2 is processed and formed by nylon reinforced injection molding.
