The S-shaped curtain hook is designed to easily pass through the curtain tape or eyelet, and its curved shape secures the curtain to the curtain track or rod.

[0003] Currently, when producing S-shaped curtain wire hooks, the cut steel wire needs to be fed into a forming device and bent into an S shape by a mold or mechanical pressure. Since there are burrs on the edges of the formed S-shaped hooks, they need to be removed using a grinding device or hand tools to ensure the smoothness and safety of the hooks.

[0004] Due to the special shape of the S-shaped curtain wire hook, when using a grinding device to grind the curved part of the S-shaped curtain wire hook, a worker is required to assist in adjusting the position between the hook and the grinding device. This process can easily cause accidental injury to the worker's hand, which in turn leads to low grinding efficiency of the S-shaped curtain wire hook, and the worker's personal safety cannot be guaranteed.
