Problems solved by technology

However, since the installation part of the adjustment arm is located close to the hub and is external, its adjustment end is often easily eroded by muddy water. After a long time, the worm is often difficult to rotate due to rust
If rubber sleeves and rubber caps are added, they tend to fall off easily due to aging, high temperature and other reasons, resulting in high instability.
