Claim 0:
1. A volute rotary resetting mechanism, comprising a rotating wheel (100) and a main shaft (200), wherein the main shaft (200) is arranged on the rotating wheel (100) in a penetrating manner;
a turntable part (110) and a resilience part (120) are axially distributed on the rotating wheel (100); the turntable part (110) is connected to the main shaft (200) through a one-way bearing (111), so that the rotating wheel (100) drives the main shaft (200) to rotate in one way;
a volute spring (121) is arranged on the resilience part (120); an inner end of the volute spring (121) is fixed on the resilience part (120), and an outer end is fixed on a volute reel (122); and the rotating wheel (100) and the volute reel (122) are relatively rotatable, so that the volute spring (121) is tightened to generate a resilience force for rotary resetting of the rotating wheel (100).
