Embodiment
Below in conjunction with concrete drawings and Examples, the utility model is described in further detail.
As shown in the figure: the motor-operating mechanism in embodiment uses two ratchet epicyclic gearing primarily of compositions such as ratchets 1, initiatively duplicate gear 2, limit shaft 3, two ratchet 4, leaf spring 5, back shaft 6, planet duplicate gear 7, gear shaft 8, internal gear 9 and shifting block 10.
As shown in Fig. 1 ~ Fig. 3, described ratchet 1 is coaxially assemblied on active duplicate gear 2 and also can relatively rotates, and ratchet 1 is installed with several circumferentially uniform planet duplicate gears 7 by some rooted tooth wheel shafts 8, and ratchet 1 plays planet carrier simultaneously; Gear wheel in each planet duplicate gear 7 is meshed with the pinion in described active duplicate gear 2; Described internal gear 9 is enclosed within the pinion in several described planet duplicate gears 7, and internal gear 9 is meshed with the pinion in planet duplicate gear 7; Described shifting block 10 is installed on internal gear 9 outer wall, and shifting block 10 outer wall is provided with boss 10a; Described ratchet 1 periphery is provided with the two ratchets 4 its part encircled, and the center of two ratchet 4 is arranged on back shaft 6, and the merging that matches of two ratchet 4 and back shaft 6 can swing around back shaft 6; Described shifting block 10 periphery is provided with the leaf spring 5 its part encircled, and described leaf spring 5 is corresponding with the boss 10a position on shifting block 10, and the middle part of leaf spring 5 curves inwardly, two ends outwards tilt, and leaf spring 5 connects also same can swing around back shaft 6 with two ratchet 4; Described internal gear 9 rotates and drives shifting block 10 to move, and drives boss 10a to contact with leaf spring 5 when shifting block 10 moves, and stirs leaf spring 5 and swings back and forth around back shaft 6 with two ratchet 4.Described boss is preferably set to triangle, can stir leaf spring 5 easily.
