Spiral Spring

A spiral spring is commonly installed between the two handles of gardening shears or hand-operated cutting tools, and serves the following functions :
• Provides an "automatic rebound" force, allowing the scissors to reopen after cutting.
• Improves operating efficiency and reduces hand fatigue.
• Enables precise control of opening and closing force.

Structural Features :
• Usually made of steel strip ( flat steel bar ), wound into a spiral structure.
• Compared to round wire springs, it provides more stable and evenly distributed torque.
