AI Technical Summary
Existing pull-out shelves require manual charging of the torsion spring during assembly, which slows down the assembly process and increases hand fatigue.
The design employs a combination of torsion body and anti-rotation teeth. The torsion spring is charged and reversed through a one-way ratchet mechanism, avoiding manual charging during assembly. The one-way rotation of the torsion spring is achieved by utilizing the engagement/disengagement state of the anti-rotation teeth and ratchet.
It simplifies the installation process of torsion springs, improves assembly efficiency, reduces hand fatigue, and ensures the stability and smoothness of torsion springs during use.
