The beneficial effects of the utility model are:
1. two compound gears that have circular cone tooth and ratchet of the present utility model act on output shaft by ratchet respectively, this two gear is meshed with the cone gear that the fixed position is arranged in both sides, during bi-directional drive, they alternately act on output shaft in the same way, the driver part twocouese moves or can make output terminal do continuous orientation rotation by less round trip, need not manual switchover.
2. the utility model has application more widely in all kinds of machinery, can be made as multiple moving runner spare according to the difference setting of wheel body, and as gear, roller, sprocket wheel etc., corresponding higher level's actuator can be gear, tooth bar, driving belt, chain etc.
3. the utility model can replace the standard bicycle flywheel, can realize the function that positive and negative driving all moves ahead (add put on-of pin and can retreat at fixed position), thereby waist and following position muscle, bone are obtained comprehensively and balanced motion and exercise, and relieving fatigue and certain brain tonic effect are arranged.
4. the utility model is used for some hand-operated tools, operating end back and forth movement in the minizone can make output terminal do directed the rotation, thereby instrument can be operated in narrow operating space, make more convenient maybe can the making of operation be operated machinery and may design compactlyer like this.
