[0002] The sun visor is a component inside a car that provides shade for the driver and passengers. It is generally connected to the car roof through a sun visor bracket assembly. To facilitate the rotation of the sun visor, the sun visor bracket assembly usually includes an L-shaped support rod and a base for fixing the support rod to the car roof. The support rod is inserted into the mounting hole on the base and can rotate relative to the base.

[0003] To prevent the support rod from falling off, an annular flange is usually provided at the end of the support rod inserted into the mounting hole, and the size of the mounting hole is tightly matched with the size of the insertion end of the support rod. When assembling the sun visor bracket, the small end of the L-shaped support rod needs to be forced into the mounting hole on the base. The traditional assembly method is manual pressing, which is labor-intensive, time-consuming, labor-intensive and inefficient. It is easy to cause damage to the material texture due to insufficient pressing or over-pressing, and the consistency of the product is difficult to guarantee. At the same time, since the rotation directions of the sun visors corresponding to the driver and passengers are different, there is a lack of anti-mistake measures during manual pressing, and it is easy for the left and right sun visor bracket assemblies to be mixed, and there is a certain chance of scrap.
