The starting point of rope 20, which, which has, takes in the two-state that the neutralization of reel 2 is pulled up, and is being pulled up shape
State, the anti-reverse part 10 are resisted against the fixed ontology 1, to limit the reversion of reel 2.The structure of the anti-reverse part 10 is as schemed
Described in 7 comprising a small cylinder 101 and a rectangle cylinder 102, rectangle cylinder 102 are arranged in small cylinder 101
Side, and deviate its radial direction, the starting point of tail end, that is, connecting steel wire ropes 20 of the rectangle cylinder 102.The reel 2
Side is equipped with the tolerant slot 22 being adapted to the anti-reverse part 10, is completely pulled out of and (is also wound on reel 2 in wirerope 20
Wirerope) before, anti-reverse part 10 is taken in the tolerant slot 22 of reel；When wirerope 20 is completely pulled out of (i.e. on reel 2 not
It is wound with wirerope), and when reel 2 inverts certain angle, anti-reverse part 10 is pulled up, at this point, only anti-reverse part 10 is small
Cylindrical body 101 is limited in the tolerant slot 22 of reel, and the rectangle cylinder 102 of anti-reverse part 10 is drawn out, and finally against
On the fixed ontology 1, continues to invert to limit reel 2, avoid wirerope reverse-winding.
In the present embodiment, the fixed ontology 1 further includes two axis wheel baffles 12, several fixed links 13, two axis wheel baffles 12
It is fixed in the support shaft 11 in parallel, between the two axis wheel baffle 12, each fixed link 13 is connected for the cooperation of two reel 2
Between two axis wheel baffles 12, and cooperate in 2 periphery of reel.The anti-reverse part 10 is resisted against wherein when being pulled up
One fixed link 13.
In the present embodiment, the fixed ontology 1 further includes the fixation baffle for allowing the shackle member 61 of the pull-push piece 6 to pass through
14, fixed 14 sets of baffle is positioned outside the pull-push piece 6, and through the fixed link 13.Wherein reel cooperation exists
Between the fixation baffle 14 and wherein an axis wheel baffle；The axle sleeve 15 is equipped with stop collar 151, and another reel cooperation is at this
Between stop collar 151 and another axis wheel baffle.In this way, making to maintain prepsetting gap between two reels 2.The fixed link 13
Specifically include first body of rod 131 and second body of rod 132, first body of rod 131 and the coaxial arrangement of second body of rod 132, and first body of rod
131 and second the external opposite ends of the body of rod 132 be connected to the two axis wheel baffle 12, first body of rod 131 and second body of rod 132
One of opposing inner end pass through the fixed baffle 14, and the opposing inner end of first body of rod 131 and second body of rod 132 plugs and matches
It closes.The work of twisted wire occurs for the wirerope that the setting of first body of rod 131 and second body of rod 132 also acts as on two reels 2 of limitation
With.
In the present embodiment, the invention also includes the cup-shaped shell 5 that inner cover 4 and both ends penetrate through, the gearshift fixes this
Body 1 is located in the shell 5, and fixed ontology 1 connects the shell 5, and the cooperation of handle 3 is at one end of shell 5, inner cover
4 are fixed at the other end of shell 5.Specifically, the shell 5 structure as shown in figure 9, its inner wall be equipped with several fixing muscles 51,
Each cooperation of fixing muscle 51 is between the two axis wheel baffle 12, and screw and two axis is respectively adopted in the both ends of each fixing muscle 51
Wheel baffle 12 locks together.For the inner cover 4 for being fixed on metope, which is distributed with several notches 41,
The other end of the shell 5 is correspondingly arranged on several convex blocks 52, and each notch 41 of each convex block 52 and inner cover 4 corresponds, installation
When, each convex block 52 of shell is first directed at corresponding notch on inner cover, and each convex block is made to move to inner cover by the one of wall by notch
Behind side, rotation case certain angle makes each convex block be against the one side that inner cover 4 leans on wall.
A kind of shift hand-operated device of the invention, there are two states for tool, and state one is as shown in figure 11, such as Figure 12 institute of state two
Show.State once, an end of fixed column 111 is located at the inner end of slideway 71, and the shackle member 61 in pull-push piece 6 blocks it
In a reel, when rotational handle 3, pull-push piece 6 drives one of reel rotation, realizes hand clothes hanger wherein
A piece airing rod is gone up and down, and another airing rod is motionless.When turning knob 8, since fixed column 111 cannot move axially,
Actuator 7 is rotating the movement (using the visual angle Figure 11 as reference) to the left under the guiding role of its slideway 71, to push actuator 7
It is moved to the left a certain distance, until the shackle member 61 on actuator 7 is detached from one of reel, and blocks another coiling
Wheel.At this point, an end of fixed column 111 is located at the outer end of slideway 71, as shown in figure 12.When rotational handle 3, pull-push piece 6
It drives another reel to rotate, realizes that another airing rod of hand clothes hanger is gone up and down.
When above-mentioned state one switches with state two, it is only necessary to can be realized by turning knob 8.Since knob 8 is visual, because
This, when user carries out gear shift operation, it is easy to expect realizing gear shift operation by turning knob 8, without seeing hand-operated device
Operation instructions, user experience effect is preferable.
In shift process, the support shaft 11 is used as load-bearing main shaft without movement, but utilizes the axial direction of pull-push piece 6
Mobile to realize gear shift operation, therefore, hand-operated device shift of the invention is steady, and vibration is small, without noise, the service life of hand-operated device
It is longer.Particularly, the present invention is whole is used as main shaft with regard to a support shaft 11, compared with the twin shaft of the prior art shifts gears hand-operated device,
Structure of the invention is simpler, volume is smaller, installation is more convenient, cost is lower.
Above-described embodiment is only used to further illustrate a kind of shift hand-operated device of the invention, but the invention is not limited to realities
Example is applied, according to the technical essence of the invention any simple modification, equivalent change and modification to the above embodiments,
It falls into the protection scope of technical solution of the present invention.
