1. Support and positioning function:
The fulcrum pin can be used as a support point in the mechanical structure to ensure the relative position of the parts is stable.
Through precise design and manufacturing, fulcrum pins can achieve accurate positioning of parts, improve assembly accuracy and mechanical properties.
2. Enhanced connection stability:
Through its unique structure, the fulcrum pin can form a stable connection between the mechanical parts to prevent loosening or falling off due to vibration or external force.
Under heavy load or high-speed operating conditions, the fulcrum pin can provide reliable connection protection to ensure the stability and safety of the mechanical system.
