Torsion adjustment device

Abstract

The present disclosure provides a torsion adjustment device, including a torsion receiving element, a force transmission module and an elastic force module. The torsion receiving element includes a transmission shaft coupled to a torsion mechanism. The transmission shaft is driven by a torsion applied by the torsion mechanism to rotate. The force transmission module includes a gear set and a gear turntable meshing with the gear set, and the transmission shaft is coupled to the gear set to drive the gear set to rotate by the torsion. The elastic force module includes an elastic element and a plurality of force-bearing balls. The elastic element is configured to generate an elastic force. The force-bearing balls abut between the elastic element and the gear turntable and mesh with the gear turntable. When the torsion is greater than the elastic force, the gear turntable is disengaged from the force-bearing balls and rotated.
