Be the operation principle of speed-change process more than, the following describes the operation principle of gearshift:

Fig. 1 is two groups of states that the wiring part is worked simultaneously, if will be wherein one group not be worked, then corresponding push-and-pull cap 18 firmly to be pushed away inward, gearshift axle 7 can strut the slip inwards that stops of top spring rod 5 toward both sides under the effect of thrust, when the Baltimore groove that slides into gearshift axle 7 and spring rod 5 during at same position, spring rod 5 will snap in the Baltimore groove under the effect of elastic force, play the effect of location, the retainingf key 24 that meanwhile is positioned on the gearshift axle 7 also can followed at the groove of shift fork 9 endoporus mobile, till retainingf key 24 is run into the inner hole groove bottom, slide inwards process in, being positioned at draw key 14 on the gearshift axle 7 can break away from doubly-linked gear 16 gradually and enter shift fork 9 inner hole grooves, because retainingf key 24 and draw key 14 on the gearshift axle 7 are set at same angle, can enter shift fork 9 inner hole grooves smoothly so draw key 14 need not be withdrawn.At this moment do not have key to be connected between doubly-linked gear 16 and the gearshift axle 7, so the power of wind part 19 just can't pass to the wiring part, wind partly is to dally; If two groups of push-and-pull caps 18 are all advanced according to same way as, partly do not work to two groups of wirings then, but wind can normally shake; Can prevent that the innocent child wind of shaking arbitrarily from damaging clothes hanger; If will allow wherein one group of state of resuming work, then corresponding push-and-pull cap 18 firmly is pulled outwardly, gearshift axle 7 will push the spring rod 5 that is positioned at Baltimore groove makes its flexural deformation disengaging spill troughed belt retainingf key 24 and draw key 14 outwards slides, up to pad 4 come to spring rod 5 draw motionless till, at this moment draw key 14 meetings are withdrawn in the gearshift axle 7 under the guiding of the interior Hole chamfering of doubly-linked gear 16 and enter into doubly-linked gear 16, along with the inner hole groove direction of rotating doubly-linked gear 16 and draw key 14 when consistent, draw key 14 ejections also stick into groove.

In addition, for above preferred embodiment, such as carrying out following distortion, for example only adopt one group of wiring from latching segment and one group of doubly-linked gear and gearshift axle or the like, so just can be applied to the situation of single pole, simplify the structure of hand-operated device, but can realize gearshift or speed changing function equally.

In sum, the hand-operated device of case of the present invention, wind is the duty of low speed when advancing, and is the high speed operation state when wind is pulled out; It is the duty of neutral that the push-and-pull cap advances, and it is the duty that loads that the push-and-pull cap is pulled out, so be a kind of hand-operated device with gear shift function.Wherein two groups of wiring devices can be controlled to be neutral or stress state separately.This hand-operated device has compact conformation, easy to operate (keeping the change direction in the push-and-pull operating process), have more hommization design (can use bottom gear when hanging heavy clothing, laborsaving; Can use top gear when hanging low weight clothing, save time), two groups of wiring device liftings simultaneously, wherein one group of independent lifting, also can two groups do not work (wind idle running), these all are that the product of selling now on the market is not available, are the optimal selections that like product updates.
