AI Technical Summary
The existing manufacturing process for lamp hooks is costly, resulting in a high overall cost for the lamps and low utilization of metal materials.
The hook is designed as a split structure, with the hook body and nut machined separately and connected by threads to avoid welding and overall cutting. It is assembled using a special fixture.
It reduces the manufacturing cost of hooks, increases the utilization rate of metal materials, reduces raw material and process costs, and simplifies the assembly process.
