Problems solved by technology

[0002]At present, due to the harsh site environment and frequent movements, the friction is concentrated at the two forks of the fork, which may easily cause the gap between the contact points to increase due to wear, resulting in poor linearity. Sometimes it will cause the contact point of the fork to break, and eventually lose its positioning effect
